History of the Squadron Post-WWII (Aircraft: Sabre 2, 5, 6, Starfighter, Kiowa, Twin Huey, Griffon)

The squadron was reactivated on 1 August 1952 as a fighter squadron in the Air Defence Command, based in St Hubert, Quebec and equipped with Canadair F-86 Sabre Mk 2s. The Squadron moved on to Sabre Mks. 5 and 6 while working out of St Hubert before deploying to Zweibrücken, Germany and becoming a part of 3 Wing, in March-April 1953. The Squadron continued in this role, operating out of Germany, for another decade, participating in many multi-national NATO exchanges and exercises with destinations including; Rabat, Morocco, Decimomannu, Sardinia and France. The squadron moved to Grostenquin, France in June 1962, but was inactive pending its conversion to the CF-104 Starfighter. On 15 December 1962, the Squadron was deactivated as a Fighter squadron and reactivated on the 17th as a Strike/Attack squadron, becoming the first Canadian squadron to be equipped with the Starfighter. This change in aircraft necessitated changes in training and tactics. In 1969 the squadron moved from Zweibrücken to Baden-Soellingen , and with that, a change from 3 Wing to 4 Wing.

The Squadron disbanded again on 1 July 1970 and was re-established on 1 January 1971 as a Tactical Helicopter Squadron with 10 Tactical Air Group of Mobile Command, later simply called ‘Air Command.’ The first helicopter used after this transition was the CH-136 Kiowa light observer helicopter and, simultaneously, the CH-135 Twin Huey utility helicopters. The Squadron participated in many operations, including: Norway, Egypt, Sinai and Central America. After switching to a fleet of only CH-135 Twin Hueys in 1992, the squadron deployed to Somalia in 1993 and to Haiti on Operations. In July 1997 the Squadron received the BELL CH-146 Griffon Helicopter fleet to replace the Twin Huey. By 1999, the Griffon’s had participated in operations in Canada and in Honduras. The early 2000’s saw rotations going to Bosnia.

On 1 February 2006, 427 Squadron became part of Canadian Special Operations Forces Command (CANSOFCOM), as a Special Operations Aviation Squadron (SOAS), with the responsibility of providing air capability to various units with the Canadian Special Forces Command, where it remains today, located at Canadian Forces Base Petawawa, Ontario . In recent years, 427 SOAS participated in Exercise FLINTLOCK, an annual regional exercise among African, Western and United States counterterrorism forces, in multiple countries in West Africa. It also deployed to the Middle-East as part of Operation IMPACT, the Canadian Armed Forces mission to build the military capabilities of Iraq, Jordan and Lebanon, and set the conditions for their long-term success.
