Medium Endurance Cutter

The Medium endurance cutter or WMEC is a type of United States Coast Guard cutter mainly consisting of the 270-foot Famous- and 210-foot Reliance-class cutters. These larger cutters are under control of Area Commands (Atlantic Area or Pacific Area). These cutters have adequate accommodations for crew to live on board and can do 6 to 8 week patrols.

Other ships in the classification are the 282-foot (86 m) USCGC Alex Haley, 213-foot (65 m) USCGC Acushnet, and the now-decommissioned 230-foot (70 m) USCGC Storis.

There are 13 vessels in the Famous class, and 14 vessels in the Reliance class. The Coast Guard plans to eventually phase out both of these cutters and replace them with the Offshore Patrol Cutter as part of the Integrated Deepwater System Program.

Ships in class

USCGC Diligence (WMEC-616) in 1965. Note the lack of exhaust stacks and the exhaust ports on the transom on the original design. Reliance class cutters would have the stack added during future overhauls.
