The Trident-class assault ship, also known as the Trident assault ship, or the Trident drill assault craft, was a model of aquatic gunship manufactured by the Colicoid Creation Nest. They were used by the Confederacy of Independent Systems during the Clone Wars. The starships acted as both attack craft and transports that could travel underwater and in space. Larger versions of the ship had a giant drill located at the bottom of the craft, which could be used to penetrate the hulls of battleships and bunkers. The ship could then release troops such as aqua droids by use of deployment racks through the hole it created.
