The Hammerhead-class cruiser was a type of warship used by the Republic Navy. This ship was a cruiser and a successor-design to the smaller Praetorian-class frigate. Serving on the line in fleet engagements as a courier and as a command ship of large fleets, it was a workhorse of the Republic and a common sight near Republic-controlled worlds. This ship could also undertake independent operations, unlike the Foray-class blockade runner, which was never observed outside a supporting fleet. Hammerheads were able to enter atmospheres and land on planetary surfaces.
