ok, I took regard of everyone's advice (the spamming problem in particular), and set out to create some other ships. This time I used a more organic style, and I think it worked out pretty well. One thing I did notice was that as I made larger ships, they got very cluttered inside, so for now I'm sticking to smaller ships and frigates. Anyway, here's the result:

Tain. A small patrol craft.
Armament: 2x custom blasters (they shoot cyan blue :3)

Karashe. A slightly larger patrol craft.
Armament: 2x custom blasters
1x missile launcher

Mahaiin. One of the main battleships.
Armament: 3x laser
3x gatling pulse cannon
2x deflector module

Mahasor. Similar to the Mahaiin, but has mini-missile launchers instead of lasers.
Armament: 3x mini-missile launcher (2 shots per cycle)
2x gatling pulse cannon
2x deflector module

Tephinar. The largest frigate. (as a measure for power, this ship can take on Nagaya's first ship on it's own, sustaining minor hull damage. All weapons but the lasers were gone after the fight though).
Armament: 2x laser
4x custom blaster
3x flak cannon
2x deflector module
2x aegis deflector

Umbeor. Light carrier. Used for long-range support. (picture's a bit dodgy, I know)
Armament: 8x demeter
4x flak cannon
