Liberator should have a bomb weapon type, that would have to be dumb fired, being affected by the ship velocity. One of them could napalm like, effective vs infantry. Another one could just scatter bombs all around. And the third one could be a nuke, and you would be able to carry only a very small quantity of these, like 1 to 4. Also, having a amp station or any resource could be required to use the nukes. Contrary to the other liberator main gun, which you absolutely cant predict where he will fire, and every time you die by it, you're wondering what killed you, the bombs would create lines of explosions on the battlefield, which would be a little bit more predictable.
