The Molotok is an extremely powerful light vehicle, with a massive turbolaser inset into the hull. This turbolaser is cable of even damaging capital ships. However, the entire ship must be brought to bear on target and the vessel is relatively lightly protected.

I built a cannon, then put a ship around. I like it, though it is a bit 2D. Molotok is Russian for hammer, I think it fits the design.
