The RCAF is looking to replace the CH-146 Griffon (UH-1Y Venom) in the near future. The Griffon was introduced into active service in Canada in 1992 and in 2012 the government announced that the aircraft would be retired in 2021 with a possible extension to 2025 if no replacement was found or late delivery of replacement aircraft. Many people ask why replace the aircraft after just 29 years, why not mod them for upgrades? The Griffon has already gone through several mod upgrades; analog cockpit upgraded to hybrid CRT/ analog displays, CRT displays upgraded to LCD and analog dials removed, 7.62 mm C6 GPMG mounted on both doors upgraded to 7.62 mm Dillon Aero M134D "Minigun" mounted on both doors, and Pratt & Whitney Canada PT6T-3D turboshaft engine, 750 shp upgraded to 900 shp. With all these upgrades that have already taken place, there is no more possible upgrades without completely rebuilding the helicopter.
In 2008 the Department of Defence (DND) stated... "The Griffon helicopter has become almost a laughing stock. It is underpowered for the transport role the army needs it to play, and it’s too big for a reconnaissance role. At a time when the Canadian Forces are thirsting for equipment, it’s telling that about 20 of the Griffons have been parked, because they can not keep up with the competition. Its engines are fine for most domestic requirements in Canada and a more moderate temperature, but [the Griffon] doesn't really have the horsepower to reach its full potential in a place like Afghanistan or in any other southern conflict close the equator."
Since then the Griffon has received engine upgrades, but still does not match the power of the Sikorsky, AgustaWestland, or Eurocopter variants. The one big thing that the Griffon has going for it, is it's speed! The Griffon is very fast for a helicopter built on 1952 design. The Griffon is actually faster and more maneuverable than the UH-60 Blackhawk.
The RCAF is currently looking at these aircraft as future replacements for the CH-146:
CH-146 Compare Tech Specs:
-Crew: 3 - 4
-Capacity: 10 troops or 6 stretchers (some sources state maximum 8 passengers in hybrid configuration)
-Gross Weight: Max. takeoff weight: 5,355 kg (11,900 lb)
-Powerplant: 2 × Pratt & Whitney Canada PT6T-3D turboshaft engine, 900 shp (671 kW) each
-Speed: Never exceed speed: 210 knots (242 mph, 390 km/h), Maximum speed: 260 km/h (139 knots, 160 mph), Cruise speed: 220 km/h (118 knots, 136 mph)
-Range: Combat Radius: 656 km (354 nm, 405 mi), Ferry Range: 1,311 km (708 nmi, 815 mi) without addition internal or external fuel
One thing that should be mentioned is that all RCAF rotary pilots are currently checked out on the CH-146 Griffon (UH-1Y Venom), CH-147 Chinook, CH-149 Cormorant (AW101 Merlin), and now the CH-148 Cyclone (H-92 Superhawk). Those are the rotary aircraft in the Canadian Forces. Although many RCAF rotary pilots are trained on the UH-60, due to joint NATO and exchange missions.
What aircraft do you think the RCAF should go with and why?
