Cutter

A cutter is a small partol craft for in-system use. In Starfleet, cutters are used by both the Merchant Marine and Military Operations Commands. These vessels are lightly armed and sheilded. Cutters are warp-capapble, and their in-system maneuverablility is very great. (FASA RPG sourcebook: Ship Construction Manual)

In emergencies or war times, cutters may be pressed into service as light attack fighters.
