I know you've changed off of the carrier but you say we'll just update our designs but there comes a point where you can't keep redesigning the same ship, at some point we will need to design new ship classes to incorporate certain technologies like maybe improved structural materials, better warp drives, gravity lifts if we go for them. Don't count on always being able to keep the design the same with some technical improvements. Also, just because we use fighters off of our cruisers does not mean our navy has experience operating a full on carrier. I remind you that it took the UK, US, France and Japan from their initial carrier experiments in the early 1920s until the 1940s to learn all the lessons they needed to about carrier operations and some of those lessons had to be learned the hard way. I'm not saying we don't know how to fly fighters off of our cruisers, we do, but a dedicated carrier is an altogether different beast.
I know non-FTL ships in BT are Dropships rather than being WarShips but we can move them out of the systems they are built in, there are jumpships regularly moving through our space that can move them. Granted those ships are mostly in Portland and there might be one or 2 intermittently in the New Helghan system itself because of the embassies unless our ships handle that. From my reading into BT, in particular into Dropships, there are such things as Pocket WarShips in BT cannon that are little more in the region of what I was suggesting. That list includes ships like the Arondight, Vengeance, Pentagon, Claymore and a variant of the Union as well as a few small carriers so having such ships used to secure important systems isn't all that alien to the BT universe which is already changing a lot just by us being here.
