The Sikorsky CH-124 Sea King is a twin-engined anti-submarine warfare (ASW) helicopter designed for shipboard use by Canadian naval forces, based on the US Navy's SH-3.  It served with the RCN and Canadian Armed Forces from 1963 to 2018.

During their service, Sea Kings were assigned to the Iroquois-class destroyers (2 per ship for a total of 6), Halifax-class frigates (1 per ship for a total of 12), and the Protecteur-class replenishment ships (3 per ship for a total 6) as a means of extending the surveillance capabilities beyond the horizon.  When deployed, each Sea King was accompanied by several crews. Each crew consisted of two pilots, a Tactical Coordinator (TACCO), and an Airborne Electronic Sensor Operator (AESOp).  In order to find submarines, the Sea King's sonar used a transducer ball at the end of a 450-foot cable.  It could also be fitted with Forward-looking infrared (FLIR) cameras to find surface vessels at night.

Sea Kings were flown by No. 406 Maritime Operational Training Squadron, No. 423 Maritime Helicopter Squadron, and by No. 443 Maritime Helicopter Squadron.

On 1 Dec 2018, the CH-124 was officially retired in a ceremony at Vancouver Island, British Columbia, concluding 55 years of service.  Of the surviving 28 Canadian Sea Kings, nine went to museums or are being displayed as monuments, 15 were sold, three were scrapped, and one is retained as a training aid.

The Sikorsky CH-124 Sea King is a twin-engined anti-submarine warfare (ASW) helicopter designed for shipboard use by Canadian naval forces, based on the US Navy's SH-3. It served with the Royal Canadian Navy (RCN) and Canadian Armed Forces from 1963 to 2018.

The advent of nuclear-powered attack submarines in the late 1950s prompted RCN leaders to assess the new threat they posed. Although these craft were noisier than older submarines and could therefore be detected at longer ranges, they were also capable of 30 knots (56 km/h) while submerged, which was faster than the top speed of the RCN's new St. Laurent-class destroyer escorts at 28.5 knots (52.8 km/h). Some RCN leaders harbored serious doubts that the destroyers could effectively pursue and destroy such fast vessels, even when operating in pairs. During a 25 February 1959 meeting of the Naval Board, it was decided that the Navy would counter the new threat by outfitting destroyers for helicopter operation.

The first of 41 helicopters would be delivered in 1963 carrying the designation CHSS-2 Sea King. The airframe components were made by Sikorsky in Connecticut but most CHSS-2s were assembled in Longueuil, Quebec, by United Aircraft of Canada (now Pratt & Whitney Canada), a subsidiary of Sikorsky's parent company, United Aircraft. On 27 November 1963, the new landing platform aboard HMCS Assiniboine was used for the first operational destroyer landing of a production CHSS-2. Upon the unification of Canada's military in 1968, the CHSS-2 was re-designated CH-124.

In the 1960s, 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 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.

A day in the life of HMCS Bonaventure in 1970. You can see deck hands holding the rotor tie down ropes to steady them on Sikorsky HO4S (Serial No. 55875) as Sea King (Serial No. 4017) takes off behind it. At the tail of 55875 you can see a deck hand with flags is giving the Sea King pilot a "thumbs up" that he is clear of 55875. Another deck hand is walking away with the chocks and two are wearing firefighting gear. Note the large speakers on 55875 just above the rear landing gear. Looks like a small DC power cart by 55875.

A developed version of the S-61/SH-3 Sea King, the S-61R was also built under license by Agusta as the AS-61R. The S-61R served in the United States Air Force as the CH-3C/E Sea King and the HH-3E Jolly Green Giant, and with the United States Coast Guard as the HH-3F "Pelican". (Wikipedia)
