Re: Starfleet Procurement Policy Draft

Another side bar, this time on tactical systems.

Just as speculative as other sections, I'm sure I'll have plenty of disagreement on this one.

Arrayed for Success: The Evolution of Tactical Systems
A starship's mission payload will commonly included a wide variety of devices classified as tactical systems. Ranging from graviton based deflector shields to particle beam weaponry, these systems often have applications outside of combat. Starfleet energy weapons have often been used in secondary functions as scientific instruments, while projectile launchers have a wide set of applications in deploying automated sensor platforms. Consequently, Starfleet designers are encouraged to provide a minimal level of tactical capability to all starships.

At its foundation Starfleet had an eclectic mix of particle and EM based weaponry at its disposal. These ranged from UESF's phased plasma weapons ("Phase Weapons"), Centauran high-energy microwave lasers, Vulcan and Andorian teytron based particle cannons, and Tellarite verteron based heavy particle cannon. Eventually a hybrid weapon was developed on New Montana's Sloane High Energy Physics Institute that combined high-intensity EM pulses with energy phasing techniques from particle cannons. Although it behaved substantially differently from traditional laser weaponry, Starfleet adopted the nomenclature of lasers to this technology and utilized it as its primary shipboard armament until the 2240s.

Energetic particles named nadions were discovered in the 2220s. Experiments conducted at the Supraluminal Linear Collider in the 2230s confirmed that phased nadion particles created an efficient energy transfer effect. Weapons applications of this "rapid nadion effect" were rapidly developed in the 2240s. The resultant phaser has remained the baseline Federation weapon technology despite substantial advancements in the intervening century and a half.

Phasers come in three principle types when utilized aboard starships. The most basic design involves a self-contained emplacement consisting of a high-capacity sarium krellide power cell, target acquisition sensors, and omni-directional phaser emitter assembly. These emplacements are then connected to the ship's primary EPS conduits that are used to feed the power cell. These emplacements are capable of firing variable intensity beams using energy stored in their power cells. Typical starship mountings involve paired emitters sharing an enlarged power cell, cooling equipment, and enhanced targeting sensors.

Modern starships utilize a substantially improved phaser design simply referred to as "arrays". Arrays consist of large connected segments of multiple phaser emitter assemblies linked to provide wide angles of fire. A single array can range from between a few score to several hundred emitter segments. Each emitter segment consists of an energy-storage prefire chamber and a discharge emitter facet. EPS conduits feed the entirety of the array, allowing all of the prefire chambers in a given array to convert plasma to rapid nadions. These prefer chambers then use an annular confinement beam to condense the nadions into a single beam released through a limited number of emitter facets. The resultant is a beam with greater destructive potential and shield penetration characteristics.

In theory longer phaser arrays feature greater power, but array segments also present a vulnerability. Compared to standard duranium/tritanium hull or even transparent duranium windows, the LiCu 518 emitter facets lack structural strength. Further, due to the effects of subspace forcefield effects on beam coherence, emitter arrays do not feature SIF-emitter integration like other parts of the hull. Finally, a phaser array can present a tempting target for threat forces, as the array's contour also corresponds to a ship's major EPS conduit network.

Despite the advantages of larger arrays, a phaser array that covers too much of a starship's surface area represents a significant vulnerability for the ship in question. Unless a starship's structural frame is specifically designed for a large emitter array, most phaser arrays consist of sub-hull segments consisting only of prefire chambers that are channeled into emitter facets with limited exposure on the outer hull. On older starship designs like Miranda or Excelsior most of these exposed emitter elements are placed in locations that once housed phaser emplacements, giving the illusion of starships continuing to use old-style ball emitters.

Greater array surface area remains a powerful advantage for modern starships. Having a greater number of emitter facets allows more flexible fire angles, faster rate of fire, and substantially improved thermal dissipation. While the total number of prefire chambers are roughly equal between a mid-2360s Excelsior (Repulse configuration, 2358) and Intrepid, the substantially greater surface area of an Intrepid main phaser arrays allows for roughly twice the fire rate and three times the thermal endurance. This reality has increased calls to either retire hull designs not optimized for surface array segments or to find practical solutions to refit more surface segments to existing designs.

The final standard variation of phasers are pulse phaser cannons, first deployed on the Defiant-class starship. Pulse phasers require larger prefire chambers than standard starship phasers plus an additional rotary drum consisting of six high density sarium krellide power cells. The combined output allows a single relatively compact 35m long phaser cannon to match the destructive yield of a full power Excelsior-class primary phaser array. Flawless microgravity grown emitter crystals and beam focusing coils layer this energy into a multi-layered pulse. The resultant bolt provides substantially greater shield penetration characteristics than even narrow-band beam blasts.

The system's complexity and fixed emitter requirement makes it a narrow arc weapon. As a result current anti-starship models of pulse phasers are limited in application to a handful of ship designs with optimized hull geometry such as Defiant, Achilles and Vesta-class starships. Substantially smaller models are used as point defense weapons aboard larger starships or tactical fighters, taking advantage of their shield penetration characteristics to shoot down shielded torpedo weapons.

Additional types of nadion-based weaponry are theoretically available for Starfleet use. These include compressed nadion beam cannon (colloiquially known as "phaser lances"), nadion pulse cannon, and photon cannon. All of these technologies remain far too cumbersome for starship use, and only a handful are used for defense of fixed installations and planetary facilities.

Projectile weapon launchers provide substantial flexibility to Starfleet ships. Variable yield warhead packages and precise control software allow torpedo weaponry to be used in everything from combat to seismic engineering projects. A typical starship's torpedo stocks contain at least half a dozen warhead configurations along with various automated scientific probes.

Starfleet torpedo launchers are based on a combination of subspace field coils and a compressed gas acceleration system. Although modern superconductors allow for extremely efficient linear acceleration utilizing magnetic fields, the fact that most antimatter based weaponry utilizes magnetic containment for their payloads precludes their use for torpedo launching. The sacrifice in comparative efficiency and the greater mass of subspace field coils is considered an acceptable trade-off when weighed against the destructive power and flexibility of antimatter munitions.

Torpedo launchers range in size from short-barrel external mount torpedo launchers in Danube-class runabouts to the 12-torpedo capacity Mk.95 burst fire launchers found on Sovereign-class starships. Casing width is standardized across the range of Starfleet torpedo types at 76cm. Other dimensions can be altered to change a torpedo's payload and guidance characteristics, ranging from the standard 25 isoton Mk.IX Photon Torpedo of 210cm x 45cm to the 100 isoton Mk.VI Heavy Torpedo at 350cm x 70cm.

The term "torpedo" has come to be used for warp capable guided smart munitions utilizing sustainer engines. In Starfleet nomenclature a "Missile" refers to a self-accelerating guided warhead equipped with a more robust propulsion system. Missiles tend to be used on craft too small even for microtorpedo launchers, often carried on external hardpoints. "Rocket" is used to describe any warhead that does not have active guidance systems, while anything that does not fit the three previous descriptions is called a "device".

All current Starfleet projectile weapons are equipped with a graviton based penetration shield. These shields are responsible for the characteristic "glow" of a standard torpedo weapon and allow projectiles to survive glancing hits from energy weapon based defenses. Further, these shields serve as a penetrator against deflector shield systems and increase the possibility that a torpedo will detonate inside a threat vessel's shield perimeter.

Found primarily on runabouts, tactical fighters, and point defense systems for fixed installations, microtorpedo launchers are more akin to rapid fire shell guns than anti-shipping torpedoes. Firing quantum, kinetic, or antimatter warheads contained in a 13cm x 3cm x 3cm casing, these weapons are capable of rapid-fire, semi-guided attacks on larger targets. Despite their dimunitive size and limited ammunition capacity, these weapons can provide a sub-1000m vessel with hitting power similar to large, high-energy beam weapons at a fraction of the size.

Re: Starfleet Procurement Policy Draft

Next full chapter. 2370 - 2381...
The Fight for Survival: 2370 - 2381
Despite coming to power as a herald of peace, Jaresh-Inyo's presidency was filled with rapidly building crises. The McAllistair Nebula Crisis of 2369 threatened to plunge the Federation back into full scale war with the Cardassian Union, undoing Amitra's hard-won armistice. A Starfleet task force led by Edward Jellico successfully forced the Cardassians to back down, but revealed the fragility of the Federation's new found peace. Other events during Jaresh-Inyo's first year in office included an incursion by Borg infected by individuality, the end of Cardassian occupation of the Bajor Sector, the discovery of the Bajoran Wormhole, and a diplomatic crisis with the Romulan Star Empire after the defection of Vice Proconsul M'Ret.

The following year, the final Federation-Cardassian Treaty led to widespread dissatisfaction and unrest in the newly established Demilitarized Zone. Groups of Starfleet officers abandoned their posts and even absconded with Starfleet hardware to assist the armed resistance group known as the Maquis. Assymetric warfare between the Maquis and Cardassian regular forces prevented Starfleet from demobilizing its forces along the Demilitarized Zone, negating the "peace dividend" expected when peace with the Cardassian Union was negotiated by the Amitra Administration.

Tensions in the Beta Quadrant direction also remained high. The diplomatic tensions created by the defection of M'Ret were exacerbated when illegal Starfleet research into phase cloaking technology was revealed in 2370. This major breach of the Treaty of Algeron nearly brought the Federation back into conflict with the Romulan Star Empire. Vice Admiral Erik Pressman refused to divulge the identities of his co-conspirators, requiring an extensive investigation of Starfleet's upper echelons by a combined Starfleet Internal Affairs and Federation Security task group. The final results of this investigation resulted in several high level resignations at Starfleet Command and Starfleet R&D, requiring substantial personnel redeployments and setbacks to existing research projects.

The ambitious 2365 Decennial Plan, expected to produce a new generation of anti-Borg optimized starship designs was hopelessly behind schedule by 2370. Admiral Batelle Toh was reassigned from ASDB to heading Starfleet R&D after the Pegasus Purges, resulting in substantial delays in ASDB development projects. Of the major projects initiated under the Shanthi Admiralty, only the Intrepid and Nova class development projects remained on schedule.

Disastrous first contact with the Dominion in 2370 resulted in the loss of USS Odyssey (NCC-71832). Further revelations in the following year led to a substantially elevated perception of danger within Starfleet's upper echelons. Despite this, the Jaresh-Inyo Administration remained steadfast in refusing calls for increased mobilization. Only the loss of Enterprise (NCC-1701-D) allowed Admiral Ruah Brackett to convince the Federation Council to activate the 6 reserve Galaxy class hulls. Authorization for series production of additional Galaxy-class hulls were denied by presidential veto in 2371, however, and Starfleet Command contented itself with procuring additional Nebula-class starships and series production of the brand new Intrepid-class light explorer.

Further conflict came in 2372 when the Klingon Empire invaded the Cardassian Union. The Federation's condemnation of the attack resulted in an abrogation of the Khitomer Accords and a series of border conflicts between the two Great Powers. Directed by a changeling who had replaced General Martok of the KDF, the brief conflict resulted in several high profile losses of isolated Starfleet vessels along the Klingon-Federation border. Already under fire for a lack of preparation in the Cardassian Demilitarized Zone, the Jaresh-Inyo Administration responded by sending Starfleet's remaining core sector fleets to the Beta Quadrant Frontier.

The combination of the Pegasus Purges, the Jaresh-Inyo Administration's production drawdown, and the revelation of the Dominion Threat allowed a small cabal of Starfleet flag officers led by Vice Admiral James Leyton to make secret preparations for a coup d'etat. Rear Admiral Galaen sh'Kelthris took advantage of his posting as chief of staff of the Starfleet Procurement Office to conduct several covert modernization projects of older starship hulls in smaller idled civilian dockyards, while the Vice Commandant of Starfleet Academy siphoned cadet squadrons off for coup preparations. As Chief of Starfleet Operations, Leyton was able to reposition most of Starfleet's assets not involved in his conspiracy outside of the Sol System. With the escalation of the conflict along the Klingon border, Leyton put his planned coup into effect. While the coup attempt was foiled by loyalist Starfleet officers, this final blow to Jaresh-Inyo's credibility effectively ended his chances at reelection.

Elected by a landslide in 2372, President Min Zife initiated a crash escalation program for Starfleet in early 2373. Taela Shanthi once again took the post of Commander in Chief, Federation Starfleet. Revelations that General Martok had been replaced by a changeling infiltrator allowed for rapid rapproachment between the Federation and Klingon Empire. The deescalation of hostilities along the Federation-Klingon border allowed redeployment of forces back to the Federation core worlds. This proved fortuitous when the Borg Collective once again invaded the Alpha Quadrant in 2373.

Unlike the Battle of Wolf 359, the Typhon Sector Task Force led by Vice Admiral Jeremiah Hayes consisted entirely of modernized, fully combat capable starships. Although Starfleet combat losses remained high with 30% of the 120 ship task force either lost or disabled, personnel losses were comparatively much lighter, allowing Starfleet to rapidly remobilize its forces by transferring personnel to newly built starships.

Under the Second Shanthi Admiralty, Starfleet emphasized procurement and modernization of proven starship designs in civilian shipyards, while using Starfleet Shipyards for repairs and construction of experimental ship types. The 2373 Procurement Memo authorized Admiral Theoderich Patterson, Chief of Fleet Yard Operations, to take "all necessary and proper measures" to prepare Starfleet for a potential war with the Dominion or Borg Collective. The Shanthi Admiralty gave Patterson the needed latitude to set production goals, while setting personnel training goals that were ambitious even by the metrics of the 2365 Decennial Plan.

Despite these preparations the start of the Dominion War in 2373 would extensively tax Starfleet resources. Pre-war estimates of both Dominion and Cardassian fleet strength proved to be wildly optimistic. Starfleet's technological edge was substantially smaller than in the Cardassian Wars of the previous decade, and the Dominion Expeditionary Force proved to be nearly equal in total strength as the Klingon Defense Force. Ship losses from early engagements numbered in the hundreds, taxing even the Federation's vast civilian ship building infrastructure's ability to replace war losses. In the year 2374 alone Starfleet lost nearly 1,500 starships (not including non-combatants such as tankers, transports, and tenders) while only managing to produce 437 new starships and repairing or refitting 600 others.

Additional pressures included high personnel losses. By mid-2374, Starfleet Operations issued directives to reduce crew complements by nearly 10% across the board. A further directive in early 2375 reduced crew complements to 80% of pre-war numbers to free up sufficient numbers to crew newly built replacements. Compared to past conflicts where loss rates were in the 10-15% range, the average destroyed starship lost 30% of its complement during the Dominion War. Accelerated officer training programs and 6-month rapid mobilization courses for enlisted crew somewhat alleviated these losses, but the major bottleneck for Starfleet mobilization during this period remained primarily personnel based.

The end of the Dominion War in 2375 resulted in the retirement of Taela Shanthi. Admiral Tujiro Nakamura succeeded Shanthi, while Chief of Starfleet Operations was filled by William Ross. The Nakamura Admiralty initiated the first post-war Decennial Plan in 2376 which sought to restore Starfleet to its pre-war strength. Resource demands required to rebuild Federation member worlds occupied during the war slowed down progress during this period. The new building programs emphasized a diverse mix of next generation starships, including the Luna, Merian, and Vesta class development projects.

Edward Jellico became commander in chief when Nakamura retired in 2380. Starfleet's strength remained about 15% below its pre-Dominion War peak at this time when it faced an unprecedented existential crisis. The final Borg Invasion of 2381 resulted in the loss of nearly 40% of Starfleet's fleet strength. Over 95% of the crew complements died aboard the lost ships, creating a crippling personnel shortage just when the Federation most needed Starfleet crews to deal with mounting humanitarian crises.

Re: Starfleet Procurement Policy Draft

I appreciate your warp nacelle design past tremendously. It very much feels like a genuine engineering introductory text. Very impressive. I see no logical inconsistencies. And I'll be using it as an assumption base from now on. I hope you don't mind.

I'll have to re-read the weapons post to fully understand it. I admit to not paying much attention to the weapons systems in the past.

And the historical overview is a nice touch. Very nice.

Very nice all around.

Re: Starfleet Procurement Policy Draft

Another side bar: Starfleet ship production capabilities and methods.

Starfleet Ship Production Capabilities
The scale of Starfleet operations requires a staggering amount of infrastructure. 75% of Starfleet's personnel requirements come from operating the vast network of starbases, outposts, fleet yards, and planetary facilities. Despite the staggering requirements, this percentage understates the Starfleet personnel dedicated to support functions. Another 10% of all personnel are employed aboard auxiliary starships serving numerous infrastructure needs ranging from fuel tankers, supply transports, and maintenance tenders to the more specialized operations of the SCE. For every crew member serving on a frontline starship, there are ten others working behind the scenes to make that deployment possible.

Filling Starfleet's vast starship production needs entirely with fleet operated facilities would require an unreasonable number of yard personnel. Starfleet demand for ship building and repair are dynamic rather than fixed, from as low as a few score per year to the thousands required during the Dominion War or after the Borg Invasion of 2381. Starfleet has taken a policy of ordering most of its basic hulls and drive systems from civilian dockyards and fitting ships with sensitive technology at fleet yards, spacedocks or starbase facilities.

Fleet Yard Operations divides starship drydock facilities into five classifications depending on the maximum volume of starships supported in each facility. These range from CLass I facilities capable of building ships of up to 10 million m to Class V facilities with a maximum capacity of 250,000 m. Smaller yards exist within the Federation's outer periphery, but Starfleet itself does not operate or contract smaller yards for its own production. Vessels substantially smaller than 50,000 m in Starfleet service are generally mass produced in enclosed planetary or starbase production facilities. Starfleet itself no longer operates dockyards of Class V size and is in the process of transfering its Class IV facilities to civilian control.

Major civilian yards in Federation space include Federation Space Systems, Salazaar Shipyards, Chiokis Starship Construction and Yoyodyne Systems Engineering. Most of these yards are designed for a mix of civilian and Starfleet orders with a heavy emphasis on Class III dockyard facilities of 1.5 million m. Smaller yards often contain a large number of Class IV or Class V facilities acquired from surplus auctions. A handful of civilian yards have Class II facilities, typically occupied by either Starfleet orders or components for orbital habitat construction.

Starfleet operates a number of large orbital fleet yards, with most of the major production focused in the Sol, Proxima, and Tellar systems. A number of Class III facilities are located outside of major population centers, but logistical requirements of fitting out preclude decentralization of Starfleet yard facilities. The largest Starfleet Yard remains Utopia Planitia Fleet Yards in Mars orbit, responsible for construction of Starfleet's largest and most advanced ship classes.

Drydock facilities assemble starship trussed frame components and external stress hulls using a combination of gamma welding and phase-transition bonding. Industrial replicators and fabricators are combined to produce structural components, while the dock enclosures are used to produce microtransporter effects necessary for phase-transition bonding. High mass components constructed of unreplicable materials like warp coils are also installed in this process, along with a temporary bridge module, basic sub-light drive coils, and a single structural integrity field generator.

Once the basic spaceframe is completed the ship is moved to a fitting out facility. These range from integrated facilities like the Class I Dockyards available at Utopia Planitia to pressurized microgravity docking bays at major starbases. A combination of high-fidelity transporters and engineering crews are used to install internal systems modules ranging from habitation units, life support systems, weapons, sensor palettes, and reactors. Fitting out can take anywhere from weeks to several months depending on ship class, payload configuration, and mission requirements..

Minor refits to a starship are conducted in similar facilities. Modular components are removed with industrial transporters or work pods, and specialist teams are called to assist in integrating new technology to the starship. Most fitting out facilities are capable of conducting limited structural repairs such as replacing exterior hull segments.

Major starship repair and refit operations require the use of full scale drydock facilities. Interior sections of a ship undergoing refit are stripped out at a fitting yard before the ship itself is towed to drydock. A combination of micro-scale transporters and work bee mounted gamma welders are used to repair structural frame components and vital systems. Major reconfigurations of external hull and replacement of warp nacelle components are also conducted during such refits. A careful quantum level survey of all ship hull components are also conducted prior to certifying the ship fit for duty.

Starfleet prefers to use their own fleet yard facilities for repairs and refits. The quantum surveys conducted during repairs and refits often reveal additional work requiring specialized expertise. Civilian yard engineers lack the experience needed to repair partially damaged spaceframes or even to spot quantum level damage structural components. As a result, they often underestimate the time and resources required to bring a starship back online. In addition, most civilian dockyards operate on a much tighter schedule for yard occupancy. A delay of as little as a week can disrupt the shipyard's operations and significantly increase the cost to Starfleet.

Starfleet starship manufacturing standards require higher resolution industrial replicators and tight tolerance fabricators than most civilian applications. Once configured for a particular ship type, replicators and fabricators can take a substantial time and resource investment to reconfigure to new designs. Most civilian yard operators will refuse contracts from Starfleet if they require frequent reconfiguration of their facilities. Many smaller operators still use older Starfleet equipment optimized for the production of Miranda or Excelsior class hull components. These yards continue to produce derivatives of older designs with updated technology. Despite the best efforts of Yard Operations Command to phase out production of these designs, the need to keep these yards in business often forces Starfleet to continue production of older hull frames.

Modern Starfleet Fleet Yard replicators and fabricators are designed with substantially greater flexibility. An integrated Class I production facility can switch rapidly between ship types and are therefore used for production of a greater variety of hull configurations and ship designs. For example, yard 37 at Utopia Planitia completed the Sovereign-class USS Gibraltar (NCC-75689) and Defiant-class USS Pactolus (NCC-76722) in 2375 without major retooling.

With the massive damage done to Federation infrastructure during the Borg Invasion of 2381, the Federation Council has requested that Starfleet Fleet Yard Operations assist in the establishing of new civilian yard facilities to support rebuilding efforts. Orders to civilian yards have decreased to free up capacity for civilian demand. Starfleet yards have also donated many of their older fabrication facilities to civilian agencies for reconstruction assistance. The donations aren't entirely driven by altruism, allowing Starfleet to increase its number of better equipped Class I facilities.

Given Starfleet's post-Destiny situation, they'd probably take whatever ship they can get their hands on.

Re: Starfleet Procurement Policy Draft

Bringing the histories up into the current TrekLit "Present".

Crawling Back from the Brink (2382 - 2385)
63 billion dead. The stark brutality of this statistic has shaped Federation and Starfleet economic policy since 2381. Starfleet's personnel losses in the invasion numbered in the millions. The total personnel and ship loss figures surpassed the entirety of Starfleet's losses since its founding in 2161. At a time of unprecedented demand for humanitarian aid and reconstruction assistance, Starfleet faced its greatest labor shortage in its history.

Admiral Edward Jellico resigned shortly after the crisis, succeeded by Admiral Leonard James Akaar. The Akaar Admiralty faced an impossible task. Its priorities included major reconstruction work in Federation space, humanitarian aid to foreign powers, rebuilding Starfleet personnel numbers and Starbase facilities, and resuming exploration missions along the Federation's frontier. The Bacco Administration's decision to maintain the deep space exploration assignments of Luna, Cheyenne, Niagra, and Andromeda class starships caused substantial controversy on the Federation Council. Deep space exploration held significant symbolic importance to the Federation public, but elected officials across the Federation were bombarded by demands for Starfleet support. Polling data on the decision was mixed, with results varying wildly from month to month.

Starfleet's immediate challenge was finding sufficient manpower to rebuild. Labor shortages were acute within Federation space and the trauma of the invasion led to a substantial portion of Starfleet personnel resigning at the end of their enlistment period. The Akaar Admiralty immediately began a program of stop-loss programs for officers and activated reserve clauses for a large number of retired personnel. Age based restrictions on enlistment were relaxed, while training programs were reduced to 3 month basic training for enlisted personnel and 6 months for officer trainees. Existing Starfleet Academy cohorts had their curriculum reduced to three years, effectively serving their senior year in the field. Finally support facility personnel numbers were dramatically downscaled, reduced to 80% of their pre-invasion numbers.

Starship crews were not immune to personnel shuffles. Plans to restore crew complements to pre-Dominion War levels were shelved indefinitely. In some cases crew numbers were reduced through elimination of smallcraft personnel or increased cross-training of enlisted specialists. Most ships were substantially undermanned, particularly in specialist departments. Larger starships were hit hardest; the typical Galaxy, Sovereign, Vesta and Nebula class starship operated at between 90-95% of its establishment in this period. USS Sugihara's experience at Ardana was sadly typical of the costs of reduced crew size. A lack of trained geologists aboard resulted in vital sensor data forecasting an earthquake being overlooked, resulting in the death of 203 Ardanans and 4 Starfleet personnel.

Significant obstacles also stood in the way of rebuilding fleet strength. Sol and Proxima's primary ship building facilities came through the invasion unscathed, but substantial numbers of civilian yards in systems ranging from Aldebaran to Beta Rigel were devastated. Demand for new civilian starships vastly outstripped supply. Further, Starfleet itself had a large number of starships with urgent repair or refit needs. Starfleet facilities were tasked with a dual task of building new shipyard facilities for civilian contractors and restoring Starfleet fleet strength.

Fleet yard commanders interpreted these priorities rather liberally, donating many of their older, smaller facilities in wholesale shipments to their contractors and building brand new Class I facilities with integration facilities and high levels of automation. By the end of the 2381 calendar year, Utopia Planitia alone had doubled its fleet yard capacity while providing nearly 70 new dockyard facilities for Sol System contractors like Baikonur Cosmodome and Copernicus Shipyards. Similar processes played out through the Federation, with an emphasis on building smaller, simpler fabrication facilities.

When Andor and its territories seceded in 2382 they possessed an eighth of Federation dock yard capacity. Substantial numbers of ships under construction were removed from Andorian yards for completion in Proxima and Tellar. With most advanced civilian yards busily producing ships for the private sector, Starfleet began contracting out orders for new hulls to extremely small private yards. Advanced facilities being in short supply, Starfleet began hauling first generation industrial replicators and fabricators out of storage to equip these new operators. Using this antique equipment, series production of Excelsior and Miranda class hulls resumed in small numbers.

Every hull is precious for Starfleet at the present juncture. Hulls once planned for scrapping have been stripped down, refurbished and rebuilt. Surplus depots have been raided for any usable hulls, with substantial upgrades implemented on designs previously slated for phase out. Despite the great challenges facing it, Starfleet remains poised to boldly go forward, a symbol of strength and stability in an uncertain galaxy.

Re: Starfleet Procurement Policy Draft

A side bar trying to explain hull geometry, time barriers, and nacelle numbers.

Geometric Complexity: Warp Nacelle Combinations
Once a starship design team has chosen the specific model of nacelle and general hull proportions based on mission parameters, the next step in design involves choosing the number and orientation of nacelles along with precise hull geometry. Both subspace and normal space physics have conflicting impacts on performance that designers must balance.

Basic structural efficiency favors spherical hull forms, maximizing internal volume while minimizing surface area. However, a true spheroid introduces substantial subspace field distortion, resulting in a phenomenon known as "subspace drag". The drag occurs as the geometric effect of the hull shape on subspace fields force overlapping warp fields to compress. The compression then distorts the field geometry at the trailing edges of the field, disrupting the coherence of the warp field and reducing its overall effect on the hull within.

The subspace drag phenomenon is more pronounced at higher warp factors and field intensities. At a high enough power level, the distortions in the warp field are no longer concentrated on field's edges and instead begin to impact segments of the propulsive bubble. Some parts of the space frame become exposed to normal space physics effects as these "gaps" in the field increase in number. Eventually hull segments begin to dissociate as relativistic effects begin impacting hull materials caught in the compression effect.

The dissociation effect occured at different field intensities depending on hull configuration, but was almost universal at fields past 400 cochrane intensity in 22nd and early 23rd century engine configurations. Originally labelled the Time Dilation Barrier due to the fact that relativistic effects were responsible for asynchronus component dissociation by the 2180s it began to be referred to simply as the "time barrier". It would not be until the 2230s that universal application of duotronic processor technology allowed field control software to compensate for subspace compression effects, effectively breaking the time barrier.

Although time dilation dissociation is no longer a factor with modern nacelle control software and coil designs, subspace drag remains a consideration in ship design. High drag coefficients begin to eat into the effective field strength of a warp field, leading to reduced propulsive performance. Starfleet's favored compromise between lower subspace drag coefficient and structural efficiency remains the saucer shaped primary hull. Greater understanding of subspace field dynamics since the 2340s has led to substantial changes from the basic truncated cylinder popularized in the 23rd century to more ellipsoid hulls.

Warp nacelle orientation and number have several distinct effects on starship performance. A typical Starfleet vessel dedicates roughly 15-30% of its total mass on warp coil. Even modern subspace field coil based impulse engines and RCS assemblies face challenges from the weight distribution of large nacelle structures. Nacelle placement makes an enormous difference in sublight performance. Designs with nacelles closer to the centerline make more maneuverable sublight combatants.

The opposite is true for warp maneuverability. The asymmetry between subspace fields projected by warp nacelles is the primary driver of warp maneverability. The further apart the nacelles, the more flexibility a ship has in adjusting its field intensity to maneuver at warp speeds. Most Starfleet vessels attempt to balance the positioning of warp nacelles to combine acceptable sublight performance with effective warp maneuverability.

The number of warp nacelles impacts the overall mass of a starship and the efficiency of its drive components. A single nacelle greatly decreases the weight distribution problems at sublight velocities and generally helps produce the "cleanest" warp field in terms of hull geometry's influence. The result is a lower subspace drag coefficient and smoother acceleration between peak transitions. Single nacelle configurations however suffer from a crippling lack of maneuverability at warp, and a difficulty with producing more than a small number of field layers.

Horizontal paired nacelles offer the greatest trade-off between warp maneuverability, general propulsive efficiency, and peak performance. Ships with horizontal nacelle pairs tend to have substantially better yaw performance, a trait often making three-dimensional tactical maneuvers at warp more difficult. This partly explains why Starfleet fleet deployments tend to feature formations with ships oriented toward horizontal rather than vertical station keeping.

Tri-nacelle designs are generally an attempt to compensate for hull forms with greater volume to surface area ratios. The third nacelle helps provide a reinforcing field layer to reduce the impacts of subspace drag. Unlike in single, dual or quad nacelle designs, the third nacelle in these configurations are not used as a main propulsion unit. This often leaves them underutilized and overequipped for such limited use. (It has also spawned the term "third nacelle" to mean an awkward tag along to a group who serves little purpose)

Finally, quad nacelle configurations offer a design flexibility at the cost of increased complexity. Quad-projected warp field geometry requires substantially more tuning to negate the impacts of subspace drag. Even the standard compression effects from drag are much larger, and a ship equipped with 4 nacelles is required to substantially reduce the amount of hull space located near or behind its warp coils. Both the Constellation and Cheyenne class starships demonstrate this principle by omitting or substantially downsizing their secondary hull. However, quad nacelle configurations offer superior warp maneuverability, particularly in unorthodox pitch and roll maneuvers, making the ships well suited to eluding pursuit or exploring regions of space "off-axis" on the galactic plane.

Coil longevity and cruise endurance are both increased in quad-nacelle designs. Lower field intensities can be used from each nacelle to sustain a given speed, allowing the use of fusion power sources to sustain integer velocities or reduce the strain of high energy plasma use on coil elements. In addition warp field manipulation software can operate the nacelles in pairs, idling the remaining pair to reduce coil strain. The cost for this increased superluminal flexibility is significantly greater ship mass. The heavier ship requires much more powerful impulse drive units to achieve acceptable sublight maneuverability.

Re: Starfleet Procurement Policy Draft

A long, rambly side-bar focusing on the evolution of Miranda-class configurations.

Snapshots of an Evolving Starship
Snapshots in the lifespan of a starship class provide a fascinating glimpse into the evolution of Starfleet technology and mission requirements. The Mirandaclass starships in particular provide a century long progression in multiple hull configurations. Changes in mission payload and propulsion technologies are quite substantial between generations. The following section examines an archtypical example of the class from 2280 to 2380. In some cases the examples are the same ship in different stages of her career.

For the sake of comparative ease, all measurements, performance specifications and classifications use Starfleet standard units of the 24th century. The anachronism of applying Revised Cochrane Scale velocities for a ship from 2280 is respectfully acknowledged, and duly ignored

2280 - 2285
In the 2280s the Miranda-class represented Starfleet's state of the art mainline cruiser. Sometimes classified a heavy frigate for political reasons, the class had a formidable mixture of scientific and tactical capabilities well suited to an era characterized by tensions with the Klingon and Romulan Empires.

USS Reliant NCC-1864
Famous for her involvement in the Mutara Nebula Incident, Reliant was a typical example of the Miranda class circa 2280, fitted with modern computer, propulsion and weapons systems. She featured an extensive internal compression hull skeleton constructed of an alloy of duranium and trititanium. In contrast to later ships of her class, she weighed in at 675,000 metric tons and had a usable payload volume of 125,000 m.

    • Smallcraft Facilities: 1 Standard Maintenance Facility

2295 - 2310
With the inaugural decennial plan in 2295, Starfleet put into production and updated version of the reliable Miranda-class starship. The first production batch initiated at Starfleet's Tranquility Base Fleet Yards were a conservative revision of the class. Unlike later designs they did not fully abolish internal stress frames, keeping most of the major transverse bulkheads. With most of the heavy combat roles now filled by Excelsior and Constellation class starships, the Miranda was classified as a cruiser with an emphasis on multi-role missions in Federation territory.

USS Himera NCC-4122
Built at Tranquility Base in 2297, Himera falls under the first production run of post-Khitomer Miranda-class starships. She featured minimal upgrades from her predecessor with a hybrid hull construction. The resultant savings in mass and volume were less than anticipated, resulting in a ship with an operational mass of 650,000 metric tons and 130,000 m. The result was a modest improvement in habitability, particularly when combined with reduced crew numbers, but nowhere near the amount expected by Starfleet logistics planners.

This first production run was considered somewhat over-built and cramped in later years, particularly compared to newer versions of the basic hull frame. They were sturdy ships that found consistent employment due to their rugged construction. In later years Starfleet made a habit of employing these vessels in lieu of more valuable ships, and Himera was retired in 2320 after an uneventful career. She was sold for scrap in 2340 after SCE surveys found her unfit for rebuilding.

    • Smallcraft Facilities: 1 Standard Maintenance Facility

2315 - 2325
Operational experience with trussed frame designs in the late 23rd and early 24th century gave Starfleet engineers and surveyors greater confidence in the soundness of the basic concept. The 2315 Decennial Plan took this into account when ordering new ship production. In particular Starfleet was eager to move more basic hull production to civilian yards. Mirandas were considered ideal learning vehicles for civilian yards still uneasy with trussed frame construction. Most Starfleet hulls conducted in the 2310s were Miranda-class frames.

USS Carthage NCC-7739
Built at Salazaar's Centauri Spaceworks facility, Carthage was among the first of the "third generation" Mirandas. Built with a full trussed frame configuration, she was a svelte 550,000 metric tons and had a usable payload volume of 145,000 m. Her LN-64N warp nacelles used coils derived from Excelsior and Apollo class technology providing a welcome boost to speed and overall range.

Internally Carthage also represented a significant advance. Hybrid quadritronic/duotronic computer cores provided sufficient processing power for the installation of general use replicators, providing significant increase in mission endurance. Her sensor suites were two generations more advanced than in the previous batch, matching the configuration of the 2310 Excelsior upgrades in capability.

Carthage served with distinction under the command of Vance Haden along the Federation's Alpha Quadrant Frontier. She served as mediator during the Betreka Nebula Incident, and later in the sporadic border conflicts of the 2340s. Among Haden's senior staff who later found renown were Rachel Garett of the Enterprise-C and Wai-Lin Li of Achilles. Carthage remains in service over half a century after her commissioning and is slated to be upgraded to Medea's configuration by the end of 2385.

2325 - 2340
The advent of widespread industrial replication in the 2330s dramatically changed the Federation's economy. Widespread displacements occured as the terms of interstellar trade changed substantially in a short period of time. The Federation Commerce Department partnered with Starfleet and the Merchant Marine to assist struggling planetary economies with adoption of replicator economics. Starfleet vessels and SCE teams were instrumental in assisting these endeavors, providing rapid transport and substantial technical knowledge to worlds in need of expertise. Miranda-class variants were at the forefront of this effort, with many hulls being rapidly converted as industrial support ships.

USS Proserpine NCC-21172
Originally completed as a reserve hull in 2318, Proserpine was activated and completed in 2332 to the support transport configuration first tried with USS Lantree (NCC-1837). As a support vessel, Proserpine had a small complement of 52 with substantial cargo room and guest quarters for Commerce Department specialists. Warp and impulse propulsion were tuned primarily for heavy hauling duties, with an emphasis on fuel economy and cruise economy at full weight. Overall mass of the spaceframe was reduced to a mere 500,000 tons, and she contained 80,000 m of ccargo space. Approximately half of this space was typically filled with industrial replication equipment for infrastructure construction.

Proserpine was a highly successful support transport, providing industrial conversions and replicator deployment for over two dozen star systems. For Proserpine's later career, consult the later entry.

    • Smallcraft Facilities: 1 High-Capacity Maintenance Bay with Class II Industrial Replicator

2340 - 2350
The mass activation of reserve hulls in the 2340s resulted in numerous novel variations of Miranda and Excelsior hull configurations. The large number of new and reserve hulls built to smaller designs during this period gave Starfleet ample opportunity to experiment. Most starships during this period had some degree of payload customization, configurations being customized by individual yard engineers to try different combinations of capabilities.

USS Antares NCC-9844
Part of the reserve hull program, Antares was originally built by Salazaar Shipyards in the 2320s before being fitted out for service in 2345. Like the Proserpine in the previous decade, Antares was fitted out to fill a particular niche. The niche in the 2340s was for a picket cruiser capable of serving as either a scout or surveyor on the Alpha Quadrant frontier. She was the first of the Miranda hull designs to be fitted with a modern isolinear computer core, allowing for high capacity sensor and electronic warfare equipment to be installed in lieu of a roll bar.

Compared to the somewhat cramped ships fitted out in the first half of the 2340s, Antares retained the habitability improvements first made on the Carthage generation of Mirandas. Her warp nacelles were changed to the light weight, high speed LN-64SL. Although mission endurance was reduced compared to existing Miranda variants, she proved to be more capable at the advanced picket role. Antares herself remains in service, serving as the picket leader for Starbase 375's attached squadron.

2350 - 2370
Miranda class hulls remained in extensive use through the middle decades of the 24th century. As newer more combat focused designs replaced them in frontline roles, more support oriented refits were conducted on existing hulls along with their major refits. In particular the introduction of the Sabre class freed Miranda-class ships from border patrol roles.

USS Saratoga NCC-31191
Famous as one of the combatants lost at Wolf 359, Saratoga is a common example of a Miranda class configuration of the 2350s and 2360s. She is a fully modernized example of the class, fitted with new equipment ranging from isolinear computers to array based phaser prefire chambers. Despite the removal of the torpedo module and phaser emitters normally carried on the roll bar structure, Saratoga had similar tactical capabilities to 2330s vintage Miranda class ships, while substantially expanding her scientific potential.

Saratoga herself was fitted out at Earth Station McKinley in 2352 as the first example of her configuration. The success of the configuration resulted in follow-up orders, including Portia and Nerissa.

USS Proserpine NCC-21172
The extensive refit of Proserpine shows the versatility of trussed frame ships. Previously configured as a support transport, Proserpine was fitted as a cruiser after her 20 year refit in 2352. She was provided a new model of roll bar equipped with a driver-coil equipped impulse engine, 2 dual fire photon torpedo launchers and enhanced targeting suite. Other changes included nacelle coils being replaced to bring her to LN-64FN3 standard, the fitting of more general purpose scientific facitilies, and the installation of phaser arrays in her primary hull.

Under this configuration, Proserpine was assigned to the Federation 9th Fleet. She was present at the McAllistair Nebula Crisis and later participated in the Typhon Sector Battle during the Borg Invasion of 2373. She was later lost in the Federation counter offensive into the Archanis Sector, protecting USS Rutledge from a ramming attempt by a K'tinga class cruiser.

2370 - 2380
The mobilization efforts of the late 2360s included experimental upgrades to existing ship designs with technology developed after first contact with the Borg. Many of these upgrades would later be applied to ships during the Dominion War.

USS Samson
Refitted in 2371, Samson was a test-bed to integrate the results of the Defiant, and Intrepid class development technologies to older hull frames. Her roll bar phaser hardpoitns were replaced by pulse phasers originally developed for the Defiant class, while she was refitted with deflector shield generators first employed aboard Intrepid. Computer systems were also up to Intrepid standards, featuring dual isolinear computer cores backed with bioneural circuitry based networks and secondary coprocessors. Overall she was a substantial upgrade that required a 6 month lay-over to complete.

For integration testing she was placed under the command of veteran officer Captain Roger Adrian and conducted war games with the Sovereign class Enterprise undergoing final integration testing of her own. The results of the war games were inconclusive on the upgrade's capabilities, as soon after the games Samson was lost with all hands as a result of Dominion sabotage. As a result of her loss modernization efforts of the remaining Miranda class ships of similar configuration were put on hold, leaving a large number unmodernized at the start of the Dominion War.

2380 - 2385
The aftermath of the Borg Invasion brought the reactivation of first and second generation industrial replication and fabrication facilities. With their limited flexibility, Starfleet chose to procure updated frames to outfit with new technology to bring fleet strength numbers back to pre-invasion levels. The result is a modern generation of older starship designs externally similar, but substantially more capable than their predecessors.

USS Medea NCC-81778
Construction of Medea was authorized on Stardate 60783.2 as part of a 8 ship contract given to the newly established Alonis Prime Space Systems. Medea used frame templates taken from the 2330 revision of the Miranda, combined with tritanium composite materials pioneered on the Merian-class starship. Changes included significant structural strength improvements along the inner saucer hull, allowing a full emitter array for her 180 segment phaser array, and a 4.5% reduction in hull mass. The reduced frame load allowed an additional 3% additional payload volume compared to the baseline Miranda configuration.

The Leeding LN-64AL4 Warp Nacelles, while using the classic cowlings of the LN-64 were internally based on the Merian's LF-51 coils. The V6S-3 class 6 warp core powering the latest Sabre-class starship was optimized for cruiser mission endurance and payloads. A pair of standard Mk. XII fusion reactor networks and two 750 milicochrane field coil based impulse engines round out Medea's propulsion system.

Overall the ship represents a high endurance, medium capability starship suited for extended deployment in Federation territory. Medea and her sister Dido are currently assigned to sector patrol and surveying duties near Starbase 197.

Re: Starfleet Procurement Policy Draft

Response to "Geometric Complexity: Warp Nacelle Combinations"

Good explainations, Nob.

Here's my view on those subjects:


Regarding the hull configuration:

In addition to your points, I always wondered what purpose the "neck" section serves.
In TNG, we can see diagrams of the Enterprise inside the warp bubble on computer screens several times. The interesting thing is that the boundary between the two warp field lobes runs through the neck.
As I see it, the reason for the neck is that this boundary should run through the narrowest part of the ship. This configuration increases warp field efficiency and stability (meaning higher possible velocities) and is the reason why the best Starfleet ship classes (the Enterprises) have a neck.
Of course there are ships with wider necks or even without one.

The Excelsior for example has a wider neck because of her transwarp drive. Stress produced by the new engine lead to sturdiness being of higher priority.

That the Sovereign has no neck may have different reasons:
She may be built for combat so a neck would be a weak point (the USS Odyssey was rammed into the neck I think). This, among other things, could explain her big warp nacelles and warp core compensating the inferior hull configuration. This explanation would also work for other, more tactically oriented ship classes.
The "weak point"-explanation would also work for the Sovereign being built for superior impulse maneuverability. Speaking for that are the huge impulse engines.

The Nova and Intrepid have no neck because they're supposed to be able to land, meaning a sturdy hull design is needed.

The Akira is fast with her relatively thin "necks" but because there are two of them, she's also sturdy enough for combat.

The Defiant, as we know, has severe problems with warp speeds higher than warp 9. This could be explained by the absence of a neck, meaning that the boundary of the field lobes runs straight through the ship resulting in a highly unstable warp field that stresses the hull tremendously. Only an extremely powerful propulsion system (as we know from dialogue she has) could make her fast enough.

Most other ship designs could also be explained this way.
Alternatively, at least from the Akira and Sovereign on, Starfleet has found a way to make a neck section redundant. If I remember correctly the problems of the Defiant were solved at some time in the series, so maybe that would speak for this too.


Regarding single nacelle starships:

In addition to bad maneuverability and slow speed, another reason for only one nacelle could be saving ressources. I believe to remember that the stuff from which warp coils are made (verterium cortenide) cannot be replicated, so if Starfleet needs as many ships as possible, a one nacelle configuration is the way to go.


Regarding four nacelle starships:

In my view, four-nacelled ships are the fastest and the most maneuverable, or, when only using two nacelles, the most endurable.
The downside is, as you said, that the warp field requires substantially more tuning, so the complexity of the engine and susceptibility to nacelle imbalance are keeping Starfleet from using this configuration.
Aditionally, verterium cortenide shortages and, maybe, higher fuel consumption would be a factor.


Regarding two nacelle starships:

They would simply be the best of both worlds, being faster and more maneuverable than one nacelle and easier to operate and more economical than four nacelles.


Regarding the odd three nacelle starships:

Alternatively, the third nacelle could be a kind of booster. It would make an ordinary two-nacelled ship faster, but in return makes the warpfield more inefficient and more unstable raising fuel consumption, increasing hull stress and reducing warp maneuverability. Also, to explain the "fifth wheel" remark, the boost gained from the third nacelle could also be accomplished with only two nacelles (modification of the warp coils or the ship's hull, for example), but it is easier to simply stick another one on the ship.

However, quad nacelle configurations offer superior warp maneuverability, particularly in unorthodox pitch and roll maneuvers, making the ships well suited to eluding pursuit or exploring regions of space "off-axis" on the galactic plane.
Are you saying that most starships have problems flying up and down on the galactic plane?

Re: Snapshots of an Evolving Starship

Very good, we need an "applause" smiley
For now, this: must be enough.

A few notes:

For the earlier Miranda's crew complement of over 300, aren't 50 triple-occupancy life boats insufficient? ... I'm thinking of the Titanic right now ^^

Type 16 Shuttlepods: Do you mean Type 18 Shuttlepods?

Flyer-class Heavy Shuttle: Is this supposed to be the same as the Delta Flyer?

Re: Starfleet Procurement Policy Draft

On the "neck" issue, I remain rather agnostic on that. I do think it's a matter of subspace field geometry, but I think that's more to do with enabling a more efficient layout combination of engines + secondary hull. "Neckless" ships in general have very small engineering hulls, though streamlining in the case of the Intrepid and Sovereign mean a slight difference there. (Their hull shape is still similar enough that they're "necked" designs).

The "off-plane" thing isn't really meant to imply other ships have trouble doing it as much as implying it's easier for a quad-nacelle ship to make rapid shifts in that direction. I'm probably going to remove it with a revision.

Quad-nacellers IMO basically give up sublight performance for warp performance. Nacelles are freaking heavy, they're by far the densest part of the ship. So tacking 4 of them onto a ship, no matter how great for warp maneuverability, endurance, or even dash speed, is an awful decision for the ship's mass balance in normal space operations. Also, The need to precisely attune their field geometry I think also makes them more vulnerable to damage.

The Miranda lifeboat figures are actually a bit lazy. I need to go back and revise them. I do figure, though, that reducing lifeboat size and volume is one of the things that also raises usable payload volume.

For the shuttlepods, I meant Type 16, which in the TNGTM are an extended range version of the Type 15.

The Flyer-class is indeed a mass produced variant of the Delta Flyer II (as depicted on the Horne from Over a Torrent Sea)

Re: Starfleet Procurement Policy Draft

Regarding the neck:

I would say then that the existence of a neck in general is, as you said, for "enabling a more efficient layout combination of engines + secondary hull", but the fact that they are so narrow is because of the benefits that has for the warp field geometry. Otherwise they would have been built wider and therefore stronger from the beginning (say, as wide as the engineering hull itself).


Regarding Quad-nacellers:

I agree on the heavy nacelles as the main reason for their rarity with the other points as further reason not to build them. The only things speaking for them are their very high endurance and dash speed.
Maybe the weight problem is also another reason against 3-nacelled ships.


EDIT: I just realized that the spindly design of the neck (together with the nacelle pylons) could be all about saving weight. They're only as strong as is needed, and more combat-oriented ships have another, more rugged design altogether.
