So I was trying to determine what legacy ship classes are still in service in 2401, other than the Sovereign-class. I was rewatching the end credits to Picard Season 3 Episode 1, titled "The Next Generation", and stumbled upon this interesting find: if you search from timestamp 51:13 until 51:19 (just 6 seconds of footage) on the episode I mentioned during the end credits, you'll see an LCARS display depicting the Earth Spacedock and a list of ship registries, such as NCC-52136 (the Steamrunner-class USS Appalachia) and NCC-80107 (the Luna-class USS Ganymede), both of which were present at the fleet formation. But wait! There's more! In addition to these two ship registries (and a couple more I couldn't quite make out) you can see four older class ships (insert Captain Picard Chain of Command part II joke here)! From what I can tell, the ships are:
At Center Left: Intrepid-class
At Upper Right: Defiant Class
At Center Lower: Sovereign-class*
At Far Lower: Constitution II Class (!?)
Now, three of these could easily be museum pieces, and perhaps Commodore LaForge was planning a sort of "starship parade" featuring the Enterprise-A, the Defiant and the Voyager at Earth Spacedock for Frontier Day, until the Changeling plot kinda threw those plans out the window. But if that's true, which ship is the Sovereign-class? There were no Sovereign-class ships in the Fleet Museum (that I know of) and the Enterprise-E sounds like it was un-flyable as of Frontier Day. But if it isn't the Enterprise-E, nor a non-musuem ship, it would have to be a ship that's still in service, which might indicate the other three are in service as well. Which makes an interesting suggestion: Are all three ships still in service? And if so, who would be flying a Constitution II class ship in 2401???
What do you guys think of all this? Granted it's just an end credits sequence, and just a background LCARS image, so it's hardly grounds for serious debate. Still, I really would like to see some "older" ships still in service. After all, just because something's old doesn't mean you throw it away.
*This could also be an Excelsior-class ship, it's kinda hard to tell, but if it is it could be the USS Excelsior, another museum ship, and an indication that Geordi's "Parade of Historical Ships" was indeed gonna be a thing, in addition to crushing my hopes that anything older than a Sovereign-class starship would still be in service.
