I certainly like 'utility carriers', but 50,000 tons is not a utility anything.
Just considering the survey component, I use 800 ton grav survey LACs, and I can't imagine wanting more than 4 in a system. It just wouldn't be efficient to have more. And for Geosurvey, most people prefer long endurance commercial geosurvey ships, which can survey everything from massive moon systems to outer system asteroids without micromanaging. Small geosurvey craft are kind of a nuisance.
The Cerberus fighters have a bit of a mismatch, 3 days crew endurance and 14 years for maintenance? I suppose those are good for patrolling a colony world for a long time. If the MSP is intended to do combat repairs, because the MSPs are a close match for the Max Repair, I am pretty sure that Combat repairs cost twice the MSPs of mere maintenance failures.
I like the Deadeye scout. 3% of cross-section of 487 tons is approximately 15 tons, or 6 MSP, the smallest signature that Aurora acknowledges.
I am impressed with the capabilities of really high tech survey fighters, but they seem to have equal mass for engines as fuel. Going with 3 somewhat more efficient engines and less fuel would make them significantly more effective, because with 5 survey points an hour, they spend more time travelling than surveying, even at their high speed.
