The enhanced structure of the shuttle allowed for the ramming of enemy vessels. Plasma torches mounted around the airlock could then open up a hole, which the airlock would seal itself around. In less than two minutes, boarding troops would be able to deploy into the target vessel.
The Katarn-class' only armament was one double laser cannon mounted at the front.
Katarn-class shuttles were often stationed aboard Nebulon-B frigates when in the Imperial forces.
Both SpecForce Marines and Imperial Navy troopers used the Katarn in boarding actions.
