Combatant Craft Medium (CCM) Mk1

The Combatant Craft Medium (CCM) Mk 1 is a relatively new addtion to the Naval Special Warfare fleet, coming into initial service in late 2015. CCMs are operated by SWCC Special Boat Teams.

The CCM is a partial replacement for the MK V Special Operations Craft (MK V SOC) (now-retired from service), and the NSW RHIB (numbers of which are to be reduced). It is a low observable, reconfigurable, multi-mission surface tactical mobility craft with a primary role to insert and extract special operations forces in low-medium threat environments. It can also provide limited fire support, carry out maritime interdiction and visit board search and seizure (VBSS) missions, counter terrorism and foreign internal defence operations.

Combatant Craft Medium Features:

The CCM features a double aluminum hull that is resistant to small arms fire. It is powered by propellors driven by 2 diesel engines. The craft features an enclosed cabin and open rear deck. The boat's construction includes shock mitigation features designed to reduce physical stress received by it occupants.

The CCM Mk1 cannot be airdropped under parachutes but it can be transported via C-17A Globemaster III aircraft (the Mk V SOC requried a Galaxy C5). The craft can be deployed from large surface craft such as the San Antonio class LPD and Wasp class LHD.
