The Cyclone is operational with the Royal Canadian Air Force (RCAF) as of 2018 and is to conduct anti-submarine warfare (ASW), surveillance, and search and rescue missions from Royal Canadian Navy warships. The helicopter is also to provide tactical transport for operations supporting national and international security efforts. In 2004, Canada awarded Sikorsky Aircraft a contract for 28 CH-148s with deliveries planned to start in 2009. Deliveries were repeatedly delayed due to development problems until the delivery of six initial helicopters in June 2015.
