After about 90 years ingame of making do with Cruiser and Destroyer sized Vessels and getting plenty of them shot to slag, I've decided to go for something bigger for a change.
With my Escorts being 10kt, Destroyers and Destroyer Leaders 15kt, Cruisers at 30kt and Heavy Command Cruisers (with jump drives) at 50kt, I figured 80kt would make a good size, the same as the brand new fleet carriers. But I'm a little stuck.

As you can see, 0.03 years of maintenance life. Now I have fast supply ships that can keep up with the fleet....but they have to supply the whole fleet, not just big mother here. I'm a bit of a loss and fairly resigned to a complete redesign, including a redesign of the engines and corresponding drop in speed, meaning the rest of the fleet will have to go slower. But I can't really see any other meaningful way to win the space needed for more engineering spaces.
A reduction in armament would make the whole thing moot. My Cruisers carry four of the same Particle Lances and 3 of the same Laser Turrets, so if I take anything away from the BB, I might as well just leave it be entirely. I've already left out the usual Emergency Cryo pods and Boat Bay (for either rescue shuttles or boarding assault craft) that my command ships usually carry.
The jump drive is the big issue, of course, taking 20% of total ship size. But making a Jump Tender of corresponding size would require the generation of MORE yard space for a substantial ship...and I already have a worker shortage.
