VOY did have quite a lot of stops in between adventures/stops, so the ship probably could have easily cruised at Warp 8 for the majority of the time (as opposed to Warp 6).
But it didn't have enough fuel and likes to explore, ergo all the side quests.
I meant, something along the lines of improving fuel and energy efficiency by 30 to 50%.
They managed to acquire technology which tripled their replicator efficiency in Season 7, so, its possible that whatever breakthroughs SF made when developing the Prometheus, they may have sent improved SIF tech to VOY, and upgrades to their power and fuel grids (I mean, in all the time VOY was gone, other Intrepid class ships would have received substantial upgrades in 6 years - aka, by the time SF sent VOY upgrades via the MIDAS array).
But that was only for Replicator Efficiency specifically.
Or the improvements would've required Voyager to be in a StarFleet Dry Dock and require a complete tear down of the ship down to it's skeletal structure and require StarFleet to retrofit the Wave Guide Conduits for next generation SIF in the skeletal structure of the vessel. Something like that isn't practical when stranded out in the Delta Quadrant and you need your ship in working order. Otherwise, they would've been able to pass on that benefit to all StarFleet StarShips already deployed. But it's probably a more fundamental design change on a deeper structural level to be able to travel that fast. Otherwise, we'd see Nebula Class & Galaxy Class be easily retro-fitted and able to go that fast. The USS Prometheus was probably the first of a new generation of StarShip design that had all these improvements cobbled together in one package. Something that will become standard later on in the 24th century with ships like the USS ProtoStar from "Star Trek: Prodigy".
That's why I posited that if 9.975 was in fact something VOY could sustain for as long as they have the fuel and energy to run it (with occasional stops for refueling, etc.) it would have been better to throw the ship over 200 million Ly's away from UFP and actually SEE the ship using 9.975 as a sustainable cruise velocity (after serious amount of repairs in the pilot and subsequent salvage of what may have remained of the Caretaker array and the scrap yard that Neelix was found in - its at least filled with raw material which could have been broken down into base matter and reconstituted into something else).
When I say 9.975 as sustainable, I mean for minutes on end, not hrs or days.
Traditional "Cruise Speeds" are seperate from "Maximum Speeds" attainable.
Trouble with the analogy (inside the Milky Way at least) is that if 9.975 is a thing for Intrepid class ships... why hadn't we seen any cruising across the Galaxy with those speeds?
9.975 was never meant to be a "Indefinitely Sustainable".
9.975 is a "Top Speed" for a brief moment in time.
You're thinking of the term
Cruise Speed. Here's the
Memory Alpha definition:
Cruising speed (also known as cruise speed or cruise velocity) was a warp speed of a starship which could be safely maintained over a period of time without sacrificing optimal efficiency. This was typically less than maximum warp speed.
Warp remains incredibly slow across SF (because otherwise, another Intrepid class ship could have been sent to intercept VOY with all the needed supplies and repair equipment to allow it to re-achieve 9.975 and get back to UFP space in a week) immediately after SF received a message through the Hirogen sensor network in Season 4).
Warp remains slow because at that point in time, technology was in a transition phase.
Don't forget that in "Star Trek: Prodigy", we effectively see the ProtoStar Containment Unit function like a Nitrous Oxide Boost for a Internal Combustion Engine. Able to propel Warp Drives to "Ridiculous Speeds" for a brief moment in time.
- What happens in the late 24th Century -
2377 - USS Voyager returns to Earth
2379 - Star Trek: Nemesis - AKA Shinzon's Coup d'état against the Romulan Senate & High Council
2380 - Star Trek: Lower Decks S1 - Show Starts
2383 - Star Trek: Prodigy S1 - Show Starts
2385 - Star Trek: Picard S1 - Synth Attack on Mars
2387 - Star Trek (2009) - Romulus is destroyed by the Hobus/Romulan star going SuperNova.
2399 - Star Trek: Picard S1 - Show Starts
Plus, other ships in the fleet were left with slow warp. Only the Prometheus was able to achieve and sustain 9.9 without issues that we know of (and this was implied to be 'fastest in the fleet' by the EMH Mark II).
StarFleet was on the cusp of breaking new Warp Speed records and about to put it into production.
USS Prometheus might be the literal first StarShip capable of going at those new top Warp Speeds
So, I don't think 9.975 was ever supposed to be a thing for Intrepid class ships... but rather 9.75 was supposed to be a sustinable cruise velocity, which then got degraded due to the ship's violent pull to the DQ (so, 9.75 could be sustained for 12 hrs only, whereas 9.9 was the purpoted maximum which would tear the ship apart in about one minute).
Prometheus Class Maximum Speeds:
Dialogue in "Message in a Bottle" suggests that warp 9.9, at which the Prometheus was traveling, was too fast for any other ship in Starfleet to catch up with before the ship crossed into the neutral zone. The Star Trek Encyclopedia (3rd ed., p. 649) suggests that a speed of warp 9.9 makes it "the fastest vessel in Starfleet." The Star Trek: Starship Spotter (p. 69) lists the maximum speed as warp 9.99, which corresponds more closely with the idea of the Prometheus being the fastest ship in the fleet, since the Intrepid-class had been previously established as capable of warp 9.975.
The Star Trek: Starship Spotter (p. 69) lists the following details and specifications:
- Dimensions: Length, 415 meters; beam, 170 meters; draft, 113 meters
- Crew complement: 141 persons
- Velocity: cruising speed, warp 9; maximum speed, warp 9.99
- Standard mission: 1 year
- Warp systems: Four LF-50 Mod 1 Advanced Linear Warp Drive Units, One LF-12X Mod 2 Compact Linear Warp Drive Unit
- Weapons: Thirteen Type XII Collimated Phaser Arrays, Three Mk 95 Diret-Fire Photon Torpedo Tubes
- Primary computer system: M-16 Bio-neural gel pack Isolinear III Processor
- Embarked craft: two shuttlecraft, four shuttlepods
The StarShip Spotter makes the most sense in terms of raw speed updates.
I never understood why this wasn't automated.
It was only automated for specific situations... and then returned to manual input (or otherwise was left for manual input).
A lot of the stuff on a starship shouldn't be left on manual and would increasingly get automated over time.
Security officers would mainly act as supervisors to the system in question (to monitor occasionally if everything works as intended) and improve upon the security measures (or at least you'd think so).
Security Officers should be in a seperate room, not on the bridge, monitoring a bank of displays that monitor the ship.
The Security Officer on the Bridge should be a liason officer to the Head of Security in his own room.
And it shold be a seperate job from Tactical Officer given how many times we see StarShips face boarding actions.
We know automated targeting is a thing... manual targeting only usually occurs if the automated system is damaged.
That's why every corridor and room should have automated Phaser Turrets in each corner along with multiple built in Multi-Spectral Optical & Holographic Sensors along with Tricorders paired with the Turrets.
Automatic Containment Force Fields should get auto-erected to uninvited Guests:
Phaser Turrets should be able to fire upon the intruders that are contained
One of the things VOY writers probably should have emphasized is the self-repair capabilities of SF ships in 24th century.
That didn't seem to be common until the time of Star Trek: Prodigy.
By then, they seem to have made mass produced ExoComps that aren't "Sentient Beings" and have them as part of the Ships Tool Set. Remember when the Murder Planet's vines wrapped around the USS ProtoStar, Hologram Janeway used the ExoComps to clean off the vines with Photonix Scrubbers AKA Send in the ExoComps to phaser away the Vines.
We know they have them... but on VOY, the writers progressively made it seem like nothing could be done without the crew as time went on. This is one of the things both TNG and DS9 suffered from. Tech got a bit dumber and dumber over time.
I don't think the Mass Produced ExoComps that weren't sentient beings were really a thing until ST:Prodigy era, ergo there was less automation and more manual input. Moving foreward from that time, you have more Robotic Helpers.
Heck, remember when the crew was originally transported to the array in the Pilot? The ship was in a state of rather serious disrepair, and while the Warp core microfracture was sealed manually, other systems continued to malfunction. But, after the crew returned from the Array 3 days later, we saw the ship filtered out the smoke, and no lights were flickering anymore - so, while the self-repair system wasn't mentioned, we have indirect evidence that it was there.
Or they could've had crew members repairing the ship, we didn't see every single crew member, and a giant chunk of the crew was rescued early on. They could've been tasked with repairing Voyager while the main cast went spelunking on the CareTaker array.
Remember that Tarses was thought to originally have Vulcan ancestry, when in fact it was Romulan, and he got away with it by simply lying about it.
But it became a problem when they found out about the lie and turned it into a witch hunt.
The Witch Hunt was misguided because Commodore Oh lay in the background in the StarFleet Security Division, slowly ranking up to Captain, & eventually Flag Officer.
I doubt Commodore Oh lied about her Vulcan/Romulan ancestry, but her loyalties were not questioned, & she wasn't monitored for signs of betrayal until she did betray StarFleet explicitly.
At the time, it was probably excusable because maybe scanners weren't perfected to find minute distinctions in DNA that would allow SF to determine such subtle differences. In fact, its possible in Tarses, it would have been more difficult due to him being only one third Romulan.
Either way, it's best not to judge an officer by their Genetic Ancestry alone.
The difference between Simon Tarses & Commodore Oh is proof that a StarFleet Officers loyalty should be questioned based on their actions, not on their genetic species ancestry.
In the case of Commander Oh, I'd imagine she inserted herself into Starfleet even before then...so she could have evaded detection similarly like Tarses had and pass off as a Vulcan... because initially, scanning tech couldn't reliably distinguish between Vulcans and Romulans... or they could but with limited success rate.
Or she was honest about her ½ Vulcan & ½ Romulan lineage and led a VERY LONG life as a double agent / deep spy.
Literally only betraying StarFleet at key moments, and not at every single incident that came across her desk.
By the time of ST: Picard, she would have ascended in rank, etc. and probably programmed the systems later on to register her as Vulcan in the first place.
I doubt it, I think she was honest with her Ancestry, because eventually the lie would be figured out and the UFP / StarFleet aren't racists. So they wouldn't deny her admission into StarFleet based on her genetic ancestry if she was up front about it and led a life of a model exemplery officer that was hard to question on the surface.
It would be interesting to see whether SF wisened up to this and improved their security measures to prevent such breaches (and what they did to do so).
I hope so, post Commodore Oh. That's the biggest scandal of the 24th century IMO.
Romulans did it with a Vulcan ambassador. How hard can it be?
It does help that Romulans & Vulcans are very similar physically & genetically.
