I don't know if the game still does this, but I believe any excess "damage" from the tractor beam not used in pulling in the opposing ship is applied to the opposing ship. So, if you use a T-Beam III at point blank range, four damage would be applied to the ship fired upon.
Now that I think about it, could be an... interesting weapon, if it still "works". I really only noticed it when I put a bunch of T-Beam, weapon, Repulsor weapon combos on a starbase, and made all of them Massive mounts (the overkill didn't occur to me, I just wanted range). It might be able to be modded to a weapon a la Graviton Hellbore, only... different
