[스크랩] 인도양에서 작전중인 캐나다해군의 CH-124 Sea King 대잠헬기

The Royal Canadian Navy was authorized to purchase 41 Sea King models in 1963, designating them CHSS-2 Sea King.

The airframe components were made by Sikorsky in Connecticut but most CHSS-2s were assembled in Montreal by United Aircraft of Canada (now Pratt & Whitney Canada), a subsidiary of Sikorsky's parent company. Upon the unification of Canada’s military in 1968, the CHSS-2 was re-designated CH-124.
The RCN developed a technique for landing the huge helicopters on small ship decks, using a 'hauldown' winch (called a 'Beartrap'), earning aircrews the nickname of 'Crazy Canucks'. The 'Beartrap' allows the Sea King to land on ships that allows recovery of the Sea King in virtually any sea state. In 1968, the RCN, Royal Canadian Air Force (RCAF) and Canadian Army unified to form the Canadian Forces; air units were dispersed throughout the new force structure until Air Command (AIRCOM) was created in 1975.


The mission of the Sea King helicopter is to enhance a ship's operational capabilities. With the helicopter's suite of radar, FLIR, and acoustic processors the helicopter is employed beyond the ship's own sensor horizon and is able to detect and report surface and sub-surface contact.

Finally, in July 2004, it was announced that the Sea Kings will be replaced by the new Sikorsky H-92 Superhawk, carrying a General Dynamics mission package, with the first of 28 CH-148 Cyclones scheduled for delivery in 2008


CH-124 : Anti-submarine warfare helicopter for the Royal Canadian Navy (41 assembled by United Aircraft of Canada).
CH-124A : The Sea King Improvement Program (SKIP) added modernized avionics as well as improved safety features.
CH-124B :Alternate version of the CH-124A without a dipping sonar but with a MAD sensor and additional storage for deployable stores.


CH-124B2 : 6 CH-124B's were upgraded to the CH-124B2 standard in 1991-1992. The revised CH-124B2 retained the sonobuoy processing gear to passively detect submarines but, the aircraft was now also fitted with a towed-array sonar to supplement the ship's sonar. Since anti-submarine warfare is no longer a major priority within the Canadian Forces, the CH-124B2 were refitted again to become improvised troop carriers for the newly formed Standing Contingency Task Force.
CH-124C : One　 CH-124 operated by the Helicopter Operational Test and Eval　uation Facility located at CFB Shearwater. Used for testing new gear, and when not testing new gear, it is deployable to any Canadian Forces ship requiring a helicopter.
CH-124U : Unofficial designation for 4 CH-124's that were modified for passenger/freight transport. One　 crashed in 1973, and the survivors were later refitted to become CH-124A's
