The Commando Helicopter Force currently operate five Sea King HAS Mk6 (CR) helicopters in addition to their complement of HC Mk4 aircraft.  The Mk6 (CR) is a conversion of retired Anti-Submarine Sea King HAS Mk 6 airframes and has a broadly similar troop carrying and load lifting capability to the HC Mk4.  The aircraft are fitted for both a Defensive Aids Suite (DAS) and General Purpose Machine Gun (GPMG).  HAS Mk6 (CR) airframes can be distinguished from the HC Mk4 by their landing gear, which is mounted on sponsons (floats) rather than stub wings.
