CH-146 Griffon

The Bell CH‑146 Griffon is a versatile, twin‑engine utility helicopter that entered service with the Canadian Forces in 1992. Developed from the Bell 412EP, the aircraft was manufactured by Bell Textron in Mirabel, Quebec, under a licence agreement that allowed domestic production and support. Over 150 Griffons have been delivered, serving in roles ranging from tactical transport and search‑and‑rescue to maritime surveillance and law‑enforcement missions. Its 1,800‑shp Pratt & Whitney PT6T-3A turboshaft engines provide a maximum cruise speed of 140 knots and a service ceiling of 20,000 feet, while the spacious cabin can accommodate up to 15 troops or 1,800 lb of cargo. Advanced avionics, including a digital flight management system and night‑vision compatible instrumentation, enhance situational awareness and operational flexibility. The Griffon’s rugged airframe, corrosion‑resistant construction, and ease of maintenance have made it a reliable workhorse in harsh northern environments. Its long‑standing presence in the Canadian Armed Forces underscores its strategic importance, contributing to national defence, humanitarian assistance, and multinational peace‑keeping operations, and solidifying Bell Textron’s reputation for producing adaptable, high‑performance rotorcraft. Future upgrades envision integrating a glass cockpit and enhanced situational‑awareness sensors, extending the platform’s service life into the next decade.
