My first thought is... are those camera-view missiles controllable by the firing player, like TOW missiles?
If so, then they should be implemented in replacement of capital ship missiles, and we need to give them an extra 5k range. Being able to fire a missile from your capship, safely hidden behind a planet, and guiding the missile out to the enemy fleet would be kickass...
Cloak thing is cool too, should be restricted to specific ships which have stealth capabilities though, and the cloaked ship should have no shields and no weapon power while the device is active. I'd say give it to ships like the phantom fighters, order recon cruiser, etc.
