The Shark class was a pod-laying strike ship developed by the Mesan Alignment Navy. The design was developed as a training ship and a proof of concept of the new spider drive propulsion system, and only 28 were constructed. They were midway in size between an old-fashioned battleship and a dreadnought (ca. 4 million tonnes). Shark-class units were too vulnerable to take part in open combat. (HH12)
