Sikorsky CH-124 Sea King
From Canadian Power Wiki
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 It has been replaced by the Sikorsky CH-148 Cyclone as Canada's anti-submarine warfare helicopter.
