[gurps] Sub Trek

[Onno Meyer]

My "Multirole Submarine" needs offensive (anti-ship/anti-sub) and defensive
(anti-torpedo) torpedoes. Both will have wire guidance, for flexible control, 
plus passive homing for the point defense torps and both active and passive
homing for the offensive torpedoes. The launchers are heavy automatic, for 
a high rate of fire. The speed is as high as possible at this TL, under the 
assumption that even the offensive fish are for self-defense and need to 
take the enemy out fast in close quarters, not in a set-piece battle.

The big hitters are MIRVed SLBMs with four 1-megaton warheads. Technically 
they're in reloadable muzzle-loaders, practically reloading needs a homeport 
or tender.

According to Wikipedia, I still need ABM and lasers, but the rules for blue-green
lasers on VXi17 are probably too optimistic.
