The Barge weapon mounts.

[AeternusDoleo]

And I'd say give it a few gunboat turrets - and a powercore that will allow it to fire a few missiles. The only <cruiser weapon with a long enough range to clear it's own hull. Give it 6 hardpoints, 2 on the sides, 1 on the front and rear. 180dgr radius of fire. It'll, if it's lucky, be able to harass a few snubs.

Barge is simply too large for guns.
