It's not uncommon for new vessels to go through minor refits at the beginning of there service lives as new technologies become available and are released fron there testing stages. As for the Excelsior, after being fitted with "conventional" warp drive engines, the control interfaces would need to be changed out to accomodate this, and in the case of Starfleet ships where "bridge modules" can be swapped out the little effort, this could be done several times during the service life of the vessel.
Yes, but the problem here is he mentions 2 different dates relating to the same refit thus implying that the refit took 2 years to complete.
I am familiar with the swapability of bridge modules. It's not the issue.

Why not Excelsior Class Technical Familiarization Resource?
My thinking here was that there would be certain quirks of the Excelsior - such as the original bridge module and transwarp engine stuff - that would not ring true for the other ships, while almost everything else theoretically would. I also wanted to allow anyone a happy degree of latitude in deciding that their Excelsior class ship was somewhat different.

However, the more I've thought about it, the more I agree with you. So edited.

Yeah, I've decided to reword to leave this vague enough that hopefully anyone can imagine this was done however they like. My original intent was that it should be vague, but clearly it was not vague enough.

Honestly, when I was writing this I was purposefully trying to imitate some of the language used in 'The Making of Star Trek' to describe the interior layout of the original 1701 - hence the food preparation systems and laundry references.

Hopefully the rewording should help with this.

Okay, so after re-reading I've figured out that the reason for the flip-flop was that it was my original intent that the refit began in mid to late 2287 and was complete by 2289. Most of this was meant to encompass refits to the new warp drive. However, you are right referring to bridge installation from two dates was confusing, so I'll henceforth refer to this refit as the '2287 refit.'

Speaking of the removable bridge module, it was interesting to read on Doug Drexler's blog that the NX-01 was designed so the entire warp core and engineering section could be slid out and replaced with an improved model. Maybe something like this could have happened with the Excelsior?

There are those plates on the top of the engineering hull which look like they could be removed to get at the innards, and the Enterprise refit had something similar around the torpedo bay - there were also what looked like hatches on the pylons, presumably for access to the conduits. An easily replaceable warp core could only increase the life of the ship.
It's funny, but Doug's thinking actually has coincided and inspired my own, but not quite in the same way. Most of the panels that you refer to on the saucer top I've actually interpreted as covers for extensive sensor systems - but I do believe that the original transwarp core was extracted through the top (where the deflection crystal(s) are) and the PTC extracted through the flat back of the secondary hull in a similar fashion.

Actually, Doug's idea has provided a pretty good solution to the Shuttlebay One quandry I've been having. Since it's been rather difficult to tell how many times that section on the original model was changed and exactly how, I've decided that the hollow volume (while still a concession to lower the ship's mass) was also designed to allow a variety of multi-mission modules, from the Shuttlebay One which is a standard configuration, to other setups that might more closely resemble the versions of the innards on the Jein Excelsior model and also the CGI models that were used.

So that's that, I think.

Okay, let's try this bit again. And for reference, here's a link to the cutaway diagram again so you can hopefully follow where I'm going. I keep kicking myself in the butt to start scanning and redrawing my deck pencil drawings, since this is little good without pictures.

Excelsior Class Technical Familiarization Resource


Structural Overview

The Excelsior’s design drew upon the now traditional primary-secondary hull configuration first introduced in the Daedalus class of the late twenty-second century. The Excelsior’s space-frame consisted of five integrated main assemblies: the primary hull (saucer section), interconnecting dorsal “neck,” secondary hull, warp nacelle pylon assembly, and twin warp nacelles (together comprising the engineering section). Each unit was constructed separately and then assembled in drydock in synchronus Earth orbit. Overall vessel dimensions are as follows: Length, 467.05 meters; Beam, 177.21 meters; Height, 74.93 meters.

The primary hull, or more commonly known as the “saucer section,” houses the main command facilities, including the main and auxiliary bridges and the main computer core, as well as crew accommodations and support facilities including food preparation and laundry systems. It also contains the main dorsal and ventral sensor platforms, and the ten primary phaser banks. A bar-like section extending aft along the longitudinal axis of the saucer section also houses the impulse reaction system and upper intermix chamber, which extends downward towards the deflector alcove in the secondary hull. Overall saucer dimensions are as follows: Length, 198.51 meters; Beam, 177.21 meters; Height, 30.71 meters.

The interconnecting dorsal is one of the components of the “engineering section.” Originally fitted with transwarp field monitoring and refinement equipment (its very horseshoe-shaped horizontal cross-sections defined by warp field dynamics), it is now primary void space, save the intermix chamber which spans it vertically and related equipment. Auxiliary crew quarters and freight space can be found here, along with inertial damper systems.

The secondary hull itself is the main component of the engineering section. It is roughly cigar-shaped in design, with a flattened dorsal and semi-circular ventral. It houses main engineering and the primary warp power systems, including the antimatter storage systems, as well as the main deflector dish. Primarily a hollow structure, the secondary hull houses the Main Cargo Storage Facility, the modular Shuttlebay One, Shuttlebay Two (at the aft fantail of the dorsal plane), and the four torpedo tubes (two fore, two aft.) Overall secondary hull dimensions are as follows: Length, 271.79 meters; Beam, 58.76 meters; Height, 43.93 meters.

The warp nacelle pylon assembly is composed of an elliptical dome from which the twin nacelles struts extend. The dome houses the main plasma manifold and EPS system, as well as various engineering support systems. Its shape is streamlined for greater warp performance, and the entire unit may be separated from the remainder of the ship in an emergency. The massive twin warp nacelles are mounted securely atop the twin support pylons. They are roughly shaped like truncated squares in cross-section, and taper to their aft ends. Overall warp nacelle unit dimensions are as follows: Length, 247.08 meters, Beam, 17.70 meters; Height, 20.33 meters.


Deck One (A-Deck)

Deck one is a fairly large space extending across the very top of the primary hull spar aft towards the impulse engines. However, the only habitable volume of the deck consists of the main bridge/briefing room area at the front, which is sunken nearly two meters into a protective ring structure. The bridge unit is an interchangeable module designed for swapout at regular refit intervals to facilitate easier control system upgrades. In keeping with Starfleet tradition, the bridge is a circular room lined with various instrument stations necessary for the operation of a modern starship.

The uninhabitable space of Deck One contains numerous systems. The protective ring around the bridge module contains auxiliary battery power and life support systems for emergency use. A bar extending aft from this unit contains the primary high-gain subspace antenna, and is flanked on either side by the uppermost portions of the dorsal sensor platform within raised hull flats. Excelsior is equipped with an extensive suite of all modern sensor modules.

Aft of this at the deck’s rear are the upper housing for the twin deflection crystals that top the intermix chamber and the upper impulse systems, including the radiative cooling unit baffles and fins. When she was originally launched, Excelsior mounted a single, large deflection crystal atop her intermix chamber. The deflection crystal allows warp power to be directly channeled to supplement the impulse system. However, flight tests proved that the large crystal tended to easily overload, so the ship’s 2287 refit and intermix chamber replacement saw the installation of a pair of smaller, more conventional deflection crystals capable of the same workload. These units have proven far more reliable and stable than the previous configuration, although some future Excelsior class ships are expected to retain the single-unit design if current research makes it more workable as is theorized.


Main Bridge

Almost all modern Starfleet ships are equipped with ejectable bridge modules, designed to be easily swappable to extend the operational lifetime of a starship, and doubling as a last-ditch lifeboat for the command crew in the event of a shipwide catastrophic systems failure. According to Starfleet regulations, the bridge module is to only be ejected once all hands have been already ordered to lifeboats. Starfleet does not favor the antiquated notion of 'the captain going down with the ship.' The Excelsior is no exception.

The bridge module originally equipped to the Excelsior at her commissioning in 2284 was quite different from the one installed during the 2287 refit for her operational career, but the two still retain similar Starfleet characteristics. The 2284 bridge module was designed around the operation of the transwarp drive. It did not contain an observation lounge as on the new module, but was still an efficient control space. The room was a perfect circle, with a single turbolift directly aft and a large viewscreen forward, comprising nearly one-third of the room’s wall space, with small secondary exit doors to either side (leading to a surrounding corridor). The remaining wall space was dedicated to control consoles. A “pedestal” in the center of the room mounted (for the first time) separate helm and navigation consoles, with Helm at starboard and navigation at port. The Captain’s chair was directly aft of these consoles.

The Captain’s chair, and indeed all the bridge chairs, was quite unusual and characteristic of Excelsior’s early career. They all mounted large inertial restraint arms that some crew nicknamed “bear arms,” so described because in transwarp flight these massive arms were programmed to automatically grab and securely hold the seat’s occupant. Also for the first time, Starfleet adopted the use of touch-screen “Okudagram” control surfaces, so named after their inventor, Dr. Michael Okuda. These controls were far more sophisticated and versatile than their push-button predecessors, and could be reconfigured for specific needs far more easily. Okudagram interfaces evolved in sophistication quickly and soon became the fleet-wide standard. “Bear arm” chairs, however, heralded the end of physical seating restraints in favor of interwoven gravity cushions and better intertial damper systems. (Indeed, the practical usefulness of seat restraints aboard starships is now felt to be dubious at best.)

The Excelsior’s 2287 refit and transwarp drive removal prompted the replacement of the 2284 bridge module, and Starfleet took the opportunity to equip her with something even more modern and cutting-edge. The new module retained the circular dome-shape for the bridge with Okudagram touch-screens, but is distinctly different from its predecessor. Two turbolift stations serve this bridge, one each at port and starboard. The viewscreen remains virtually unchanged, but is slightly smaller, and gone are the forward corridor access doors.

Stations lining the bridge walls include: engineering support, propulsion, communications, and tactical monitoring at port; three dedicated science statsions and a small master control monitoring station at starboard. The upgraded Captain’s chair and helm and nav consoles retained nearly the same locations on a platform level with the circumferential stations. A small table has been provided in front of the Captain’s chair for his convenience. An alcove at the aft of the bridge houses the new master situation display, a graphic of the ship that allows the Captain to view the ship’s status at a glance over his shoulder. Doors flank the MSD, which allow access to the new briefing room/observation lounge, and an adjacent head for the bridge crew’s use.

Briefing Room/Observation Lounge

The new observation lounge provides an unparalleled view of the aft portion of the ship and the warp nacelles, and was designed to allow the senior staff a more convenient location for mission briefings. It features a long, slightly curved table fitted with computer access systems and chairs for each member of the senior staff. Each end wall is fitted with a fairly sizable viewscreen and data interface for briefing sessions. The inner wall is decorated with art and other personal decorations provided by the Captain. The Captain may also use the room as a ready room if so desired to relax when key situations require his proximity to the bridge.

JNG was right regarding my intention with using 'mounting.' There are a couple of things like this (such as 'turbolift stations') that I purposefully wanted to keep as anachronistic.

Deck Two (B Deck)

Deck two is an almost fully habitable deck that forms the uppermost part of the primary hull dorsal spar. It features the centrally located top of the main computer data transfer trunk, where it mates with the bottom of the bridge module. The trunk spans the space from the main processors on deck seven up to the bottom of the bridge module at the top of deck two, facilitating rapid data transfer to key command areas in the saucer. Additional data transfer conduits branch from the central trunk like branches of a tree, eventually stepping down to transfer conduits mere millimeters in diameter where they meet control interfaces. The ship’s fourteen science labs are located on this deck, adjoining the computer core trunk, where they are directly fed data by the dorsal sensor platform above. In addition, quarters for VIPs such as diplomats and admirals are found on this level. In a small uninhabitable section at the front of this deck are additional sensor modules for the dorsal sensor platform, with related systems.

Aft, the main stairwell top is found. The stairwell provides easy access to the ship’s main decks in the event of an emergency. Further aft is the lower deflection crystal housing, with a dedicated monitoring room. The crystals shed brilliant patterns of light across the room’s bulkheads as they surge with raw power, just atop the warp intermix chamber. Aft of this is the upper part of the multi-level impulse reaction system, including the upper parts of the fusion reactors and coolings systems, and the twin engine assemblies and exhaust units.


VIP Quarters

These quarters provide accommodation for visiting officers, ambassadors and their wives or husbands, and Federation government officials, among others. Each stateroom is composed of two areas that are separated by a retractable partition. The room's entrance opens into the sleeping area, which is generally outfitted with two twin beds. A translucent door leads into the bathroom area, which features both a sonic shower and a jacuzzi tub, as well as an adjacent clothes closet.

The other half of the stateroom is a work and living area. A library computer and work desk are provided for guest use, for which instructions are provided. A circular dining booth is provided for guests who prefer to eat alone or work privately during their meal. A viewscreen station stands against one wall. Here, guests may contact their home worlds by subspace radio, if necessary, or may simply choose from thousands of entertainment files from the ship's computers for viewing. A small storage closet is provided for those with luggage or small personal cargo which cannot be stored in the cargo decks. Personal items may be stored on a bookshelf above the beds, or in a set of roll-top cabinets in the living area wall. A food slot is also provided for guest convenience.


Impulse Reaction Systems

Impulse engines are the main form of propulsion at sublight speeds aboard a starship; they are used for travel within a solar system or areas of space where warp drive can not function. The engine is a basic fusion system with vectored exhaust, not unlike a solid propellant rocket of the past. The standard speed for impulse power is .25c, but engines can propel a ship into the .8c range at the cost of time dilation effects.

Impulse engines have changed little since their inception over 100 years ago. The impulse engines found on Excelsior are made up of three main parts, and are the largest ever constructed. First is the impulse reaction chamber, where deuterium slush is fed in and a fusion reaction takes place. Excelsior has ten fusion reactors, five per engine. Each of these units can be ejected in an emergency. The plasma created by the fusion process is then fed into the second stage of the impulse engine, the accelerator/generator. During space flight mode the plasma is accelerated by the second stage and passed onto the third stage. The A/G can also use part of the impulse engines power to supply ships systems by feeding the plasma into the ships EPS lines. The engines are able to drive the ship and provide power simultaneously if needed. Conversely, warp power from the intermix chamber can be channeled through the deflection crystals into the impulse engines to provide power for them. The final stage of the impulse engine is the vectored exhaust director. This stage directs the flow of the impulse engine exhaust to allow free movement of the ship on any axis.

Traveling at high impulse speed, greater then .25c, has a price. Since it is non-warp speed, general relativity still applies. As impulse speed increases past .75c, time slows down aboard the ship and passes faster in the rest of the universe. Starfleet regulations specify the avoidance of high impulse velocity except in extreme circumstances. Current research into mass-reduction impulse systems could one day provide a means of reducing these relativistic effects, but true breakthroughs in the area are likely fifty years or more away.

Re: Excelsior Technical Manual - Revived!

OK, the last paragraph. If they traveled at high impulse, from the crew's point of view (due to time dilation) they would have less time to prepare. Also, the time required to intercept using impulse as opposed to the faster warpdrive would, from the rest of the universe's standpoint, be longer. Hence V'ger would be closer to earth. So how is it in anyway an advantage for them to intercept slower AND have less time to prepare?

Yeah, the V'Ger thing was a bad idea.

Hi Praetor,

Here are a couple of graphics that might help you out with your project, there are only 2 of them for now, but I will be posting more. Your work has really inspired me. Keep up the good work.

Re: Excelsior Technical Manual - Revived!

Those are really awesome, Nimitz CO, thank you.

Inspiring enough to make me kick myself in the pants and get back to work. Tomorrow.

Re: Excelsior Technical Manual - Revived!

I continue to thoroughly enjoy the technical manual, Praetor. I know I'm a little late to the editing party for the last chapter, but I did have a small suggestion. I wonder if you'd consider avoiding use of the term "dorsal" to describe the necklike structure connecting the primary and secondary hulls. I don't know where that use of the term originated, but it's always irked me as it's (AFAIK) a completely improper use of the word. How about "interhull" as an alternative?

Also, you may have described your reasons for this in greater detail, but if so I missed it: it was a little disappointing to hear just how much void space there is in your Excelsior design. IIRC, most of the aforementioned interhull and secondary hull are full of a whole lot of nothing. Is this to keep the ship's mass in line with a previously-established figure?

I can't wait until we get to the nacelles. Please tell me you're going to spend at least a good chunk of a chapter on field grills and flux chillers!

BTW, hats off to Nimitz CO for the development project mission logos and the cover design. Seeing the "possible cover" was the first thing that made me believe I could actually see this thin in print one day -- even if it was just a limited run for the folks on this BBS. I know I'd buy one, Praetor. (And if that happens, consider me at your disposal to record an audio version -- long-form voiceover is what I do.)

Looking forward to more of this wonderful work.

They're fantastic. The only comment I'd make is the "Workhorse of the Starfleet" tag - surely "The Great Experiment" is more fitting?

Thanks Tomalak for the nice complement, I chose "Workhorse of the Starfleet" as the motto for the class emblem to reflect every Excelsior Class vessel in service. I'm using the motto "The Great Experiment" for the USS Excelsior NX-2000 logo (hopefully I'll have that up in a day or two) that they were using during the Transwarp and shakedown trials, before it was changed to the operational emblem when it was taken off of experimental status and issued her perminate NCC number when the motto of ship was changed to "No Matter Where You Go, There You Are"
