[Garth Vader]

I just finished playing a game as a psychic race. The Cue Cappa was also in the game. They would come through the warp point with about 10 dreadnaughts, I would hit one ship with an allegiance subverter from my base. Then I had control of that ship. Since it was the first turn it could fire it's 2 allegiance subverters, and so on until I had their entire fleet.

I never had to build any of my own dreadnaughts, I captured so many I didn't know what to do with them!
