No, not the fighter, the carrier that Carl referred to
It was de rigeur in small ship CT universes for all capital ships to be hybrid cruiser-carriers, and SLOW... in part, because without Bk 5, there was nothing bigger than the triple turret, and there was the 1 turret per 100Td limit. At 3000 Td, with maxed drives, you get:
3000 Hull
__60 Bridge
___9 Model 7
_125 Jump Drive Z=4
__47 Maneuver Drive Z=4
__73 Powerplant Z=4
__40 Fuel PP
1200 Fuel JD
_172 43 SR for crew - CO, XO, P,N, M, 5E, 3A, 30G
__30 30 Turrets.
1246 unaccounted for.
just over 40% unaccounted for. It can be cargo, or it can be small craft. For a pure warship, the ONLY viable choices are marines or fighters.
Note: TL15 Bk2 design, due to Drives Z.
At TL 13 (& 14), it's maximum ratings are J1 M1 P1. TL13 is drives Q,
3000 Hull
__60 Bridge
___9 Model 7
__80 Jump Drive Q=1
__29 Maneuver Drive Q=1
__46 Powerplant Q=1
__40 Fuel PP
_300 Fuel JD
_172 43 SR for crew - CO, XO, P,N, M, 5E, 3A, 30G
__30 30 Turrets.
2264 unaccounted for.
Similarly large tonnage surpluses at lower tonnages with lower tech levels. The only way to use that tonnage for improvement of combat potential is either duplicate drives (which are offline until better than the mains, and then take over), to carry marines, or to carry fightercraft.
A fighter under Bk 2 takes 10 for the fighter, and 4 for the pilot.
