Well you really only need one bigger texture(e.g.1024)
What you can do to up the details depends heavily on the engine you are using.
You could:
a) lay out the geometry of the Submarine so you can reuse one detail texture all over (e.g. have a 64x64 bit of texture and slap an assorted array of polygons on there to get 'windows')
b) you could mirror your texture and thus get 2x the amount of detail
This does rarely work with normal maps so this is heavily engine dependant.
c) use 'decal textures' to get more details going (if your engine supports this)
d) if all else fails - break up your model into several pieces and texture these.
Hope this helps - i love what you're doing btw :)
