The Sikorsky CH-124 Sea King is a twin-engined anti-submarine warfare (ASW) helicopter designed for shipboard use. The Canadian variant is based on the US Navy's SH-3 (or S-61) and has been continuously in service with the Royal Canadian Navy and Canadian Forces from 1963 to 2001. It has been replaced by the Sikorsky CH-148 Cyclone as Canada's anti-submarine warfare helicopter.


  • 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 formerly with a MAD sensor and additional storage for deployable stores.
  • CH-124B2: Six CH-124Bs 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.
  • CH-124C: One CH-124 operated by the Helicopter Operational Test and Evaluation 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 four CH-124s that were modified for passenger/freight transport. One crashed in 1973, and the survivors were later refitted to become CH-124As.
