12 Wing Shearwater

12 Wing is the home to the Maritime Helicopter community and centre of naval aviation in Canada. Home of the state-of-the art, combat capable CH-148 Cyclone, 12 Wing is responsible for providing maritime helicopter support to the Royal Canadian Navy (RCN) with Helicopter Air Detachments (HELAIRDETS) for missions at home and around the globe. 12 Wing is Head Quartered at Shearwater, Nova Scotia.

12 Wing Shearwater is home to 12 Air Maintenance Squadron (AMS), 423 Maritime Helicopter (MH) Squadron, and 406 Maritime (M) Operational Training Squadron with 443 Maritime Helicopter (MH) Squadron operating out of 12 Wing Patricia Bay, British Columbia.

Personnel and aircraft are deployed around the world primarily as part of HELAIRDETs that deploy with RCN ships on the East (423 Maritime Helicopter Squadron) and West (443 Maritime Helicopter Squadron) coasts. While deployed with the RCN the personnel integrate as part of the ship's crew and the embarked helicopter acts as an extension of the ship which enhances and extends its sensor and weapons delivery capability.

Successfully passing the milestone of Initial Operational Capability (IOC) for the CH-148 Cyclone in June 2018, allows the community to continue in the role of maritime operations for the Royal Canadian Air Force for many years to come. Although the Sea King was one of the busiest Aircraft in Canada's Air Force, participating in a variety of international and domestic operations for the last 55+ years, the CH-148 Cyclone will now assume that role. The first Operation Deployment of the Cyclone, took place in July 2018, as part of OP REASSURANCE.

Celebrating the departure of the longest servicing aircraft in the CF, the CH-124 Sea King Helicopter - which has faithfully served Canada for 55+ years - will be retired from service and conducting its final flights at 443 (MH) Squadron in December 2018.

In praise of the Hurricane

In the epic battle of summer 1940 over British skies, much praise was heaped on the “Few”—deservedly so—and the sleek, all-metal Spitfire fighter which was credited with defeating the mighty Luftwaffe. But, wait a minute! What was that other aircraft doing shooting all those bombers down during the Battle of Britain? It was the slower, more maneuverable and steadier gun platform: the Hawker Hurricane.
