CH-148 Cyclone

The CH‑148 Cyclone is a maritime‑focused, twin‑engine helicopter developed by Sikorsky Aircraft Corporation for the Royal Canadian Navy. Its origins trace back to the early 2000s when Canada sought a replacement for the aging CH‑124 Sea King fleet. After a lengthy procurement process, Sikorsky’s upgraded version of the S‑92, designated the CH‑148, was selected in 2004 and entered service in 2015. The Cyclone incorporates advanced avionics, a glass cockpit, and an integrated tactical mission system that supports anti‑submarine warfare, surface surveillance, and search‑and‑rescue missions. Powered by two General Electric CT7‑8A turboshaft engines, it delivers a maximum take‑off weight of 20,000 lb and a range exceeding 400 nautical miles, enabling operations from both the Halifax‑class frigates and offshore patrol vessels. Its rotor system features a five‑blade composite main rotor that reduces vibration and noise while enhancing lift. The CH‑148’s significance lies in modernizing Canada’s naval air capability, providing a versatile platform that aligns with NATO interoperability standards and advances the broader field of maritime helicopter design. Continuous software refinements also improve mission planning, situational awareness, and crew workload management.
