Things I am not sure about:
- Somewhat smaller starships. Starship technology could be designed in such a way that the ideal Battleship is about 20K dtons, not 200K. This scales better with the smaller ships - a Gazelle would be a credible escort, not an insignificant speck. Of course, extremely large freighters and space stations should still exist.
I like the large space ships, because it underscores how the Navy rules the stars because they're the ones crewing 100K+ warships.
As for making smaller ships relevant, think of the real world. The USN has the massive Nimitz class supercarriers, but they also have patrol ships because not every mission needs a supercarrier. The Coast Guard gets around on cutters as well.
To use that as an analogy, your 100 or 200K warships can exist in the same universe as a 400t patrol ship. There are never enough patrol ships anyway.
What I would change is the type of ships we do get in the Navy. You want to design your ships for the mission they're expected to perform. Therefore, I would have classes focused on: assault carriers which carry thousands of troops plus landing craft; battle cruisers, the main ship-of-the-line which can operate independently or in squadrons, smaller escort vessels that stick close to the assault carriers, and patrol ships that are more numerous than the other three. I would also have tanker/supply ships, courier boats, and hospital vessels for non-combat roles. System Defence Boats and Monitors are a given as well.
Armaments would be the same as what we're used to - spinal meson mounts, protected by meson screens, and secondary armament consisting of particle accelerators, missile bays, and fusion bays. Lasers for point-defence, although I would reimagine sandcasters as a kind of chaff countermeasures (as opposed to a laser-beam-dispersal system).
I would get rid of nuclear dampers, however. For one thing I never liked the idea, and I want to keep nuclear missiles as an offensive problem for ship commanders, plus I would want fighters to be carried onboard battle cruisers. If a space fighter can be armed with a nuke then they might actually pose a threat to a cap ship.
I would change the fuel requirements for jump drives. I would have it as a blanket 15% of hull reserved for one jump. Higher TL jumps give higher ranges, but this is as a result of better navigation paired with better understanding of the jump drive. But for sanity's sake, most ship designs actually reserve 30% of the hull for jump fuel, so that you can jump twice if needed.
