While possible I'd rather see a new, different, warship classes being put together at Quatre Belle. Too many Lev III's will turn space combat into a joke. The Ravens are also much more resource poor than the Dominion, so if it's taken them 12+ years to put one together, then it's probably gonna take the Ravens longer.
I suspect we'll see something completely new, but in the vein of the Lev III, probably something along these design parameters:
- Decently sized, maybe as high as a million tons, unlikely to be more, but probably smaller than that, I'm expecting "battlecruiser" sized.
- Good anti-fighter, capital missile, and PWS defenses - probably using a large number of NLs and AMS.
- Large number of DS collars compared to its size, maybe even maxed out. With low numbers of warships in the universe, something capable of standing alone against large numbers of PWS is likely to be considered. And what better way to counter PWS than with your own PWS? ARTS SC bays are likely to remain a thing too.
- Integral ASF attachment is likely to be smallish, no more than the 60 the Lev III carries and likely closer to 30 or 40.
Once the prototype is produced, and the production kinks are out of the way, I could see a new one of these rolling off the line about once every 3ish years (and a Lev III once every 5ish).
Edit: Okay, that's really optimistic, but a guy can wish can't he. xD
