Marauder

The Marauder-class refines volatile gases into three categories the Crimson Fleet cares about: fuel for the fleet, explosives for ordnance, and chemical components for weapons systems. The refinery processes run at temperatures and pressures that violate every other empire's safety standards, which the Fleet considers a competitive advantage. Two weapon mounts protect gas processing operations in contested nebulae — the Fleet learned that losing a full cargo of refined volatiles to a pirate raid is more expensive than the guns.
