History of the Squadron Post-WWII (Aircraft: Harvard II, Mitchell III, Silver Star, Expeditor, Otter, Sea King, Tracker, Cyclone)

The unit was re-formed as a reserve unit, 406 Tactical Bomber Squadron (Auxiliary) on 1 April 1947 at RCAF Station Saskatoon . It flew B-25 Mitchell III light bombers, and also Harvard and T-33 Silver Star aircraft for army co-operation duties. It was re-designated 406 (Light Bomber) Squadron on 1 April 1949 and adopted the title City of Saskatoon in September 1952. In March 1958 under the name 406 Squadron, it was re-equipped with C-45 Expeditor and later CSR-123 Otter aircraft, and assigned to a light transport and emergency rescue role. The squadron was disbanded again on 1 April 1964 as a result of the reduction of the Auxiliary Force.

The squadron was re-formed for a third time at CFB Shearwater, Nova Scotia on 12 July 1972 as the 406 Maritime Operational Training Squadron, operating the CH-124 Sea King helicopter and the CP-121 Tracker ASW aircraft. In mid-1981, the operational Tracker squadron, 880 Maritime Reconnaissance Squadron, was transferred CFB Summerside, which left 406 Squadron only responsible for Sea King training. At the present time, the squadron trains pilots, Air Combat Systems Officers (ACSOs), and Airborne Electronic Sensor Operators (AES Ops) on the CH-148 Cyclone aircraft and flight operations relevant to the Maritime Helicopter (MH) role. In addition, the Squadron’s Technical Training Flight conducts a wide range of avionics and aviation courses for Cyclone technicians, as well as specialty maintenance courses. On an annual basis, between 200 and 300 students graduate from 406 Squadron. The squadron’s partner squadrons 423 Squadron in Shearwater, N.S., and 443 Squadron in Patricia Bay, B.C., employ 406 Squadron Cyclone graduates as integral members of helicopter air detachments aboard Her Majesty’s Canadian ships.
