The Combatant Craft Medium, Mark1 (CCM) is a United States Navy patrol boat designed for use by the United States Naval Special Warfare Command as a multi-mission surface tactical mobility craft built by Vigor Industrial "to provide small-caliber gunfire support, infiltrate and exfiltrate Special Operation Forces, conduct VBSS (Visit, board, search, and seizure), special reconnaissance, coastal patrol and interdiction, counter terrorism operations, and FID (Foreign Internal Defense)," per the U.S.

Oregon Iron Works and United States Marine, Inc were awarded initial contracts to develop their existing concepts into the CCM in September 2011, with Oregon Iron Works winning the selection process to produce a total of 35 CCMs over 7 years by United States Special Operations Command in February 2014.

[4][5][6] The first CCMs were delivered and commissioned in 2015, featuring a low observable profile, with longer range, operable in higher sea states, and with increased protection and shock mitigation for its crew and passengers than the NSW RHIBs it replaces.

Its electronics package includes a remote weapon station and sensors, Blue Force Tracker, a DAGR jam-resistant GPS receiver, and advanced tactical radios.

[4] In May 2023, it was announced that Norway's Naval Special Operations Command gained approval from the Pentagon to acquire 2 CCMs to be delivered in 2025.
