Only that it is smaller in width, weight and block count while still having the same features internally. Also that this was made after the jump drive update, so the engineering and aft section of the ship is much more tidy.

Hey, may I ask what the key differences between this and the Tormentor I are? I haven't had the chance to really, REALLY look at them yet, and probably won't be able to any time soon.

Ah ok, i get it so the goal was not to make it self-sufficient but rather as an additional oxygen support.
Well i just thought, since the design would have had space for a couple more of them ;)

@Whaddageek : Ok thanks, I'll find a way to incorporate that!
@Joshua Norton: Thanks! No they're not the key to the oxygen system, although they keep the consumption of ice lower when using the bridge. At least that was the idea :)

Nicely done, i like it but don't you think the 2 oxygen farms are a bit insufficient?

You can easily fix the connector-fiddling during launch by just turning them off on the fighter after unlocking them.
