Bell CH-146 Griffon

The CH-146 Griffon is forecast to be retired in 2021. Bell Helicopter Textron Canada Inc. was awarded a C$640 million contract to overhaul and repair the CH-146 fleet until retirement in 2021. The contract includes options to extend the contract up to 2025 if necessary.[5][6]

In January 2019, Canada announced plans to modernize and extend the life of the existing 85 CH-146 helicopters to 2031.[7]

The CH-146 Griffon have been deployed in various operations in Canada since their introduction in 1995. They have been deployed during the Operation Saguenay in 1996 and Operation Assistance in 1997. The CH-146 have also played a major role during the great ice storm of 1998.[9] They were deployed during the 28th G8 summit and 36th G8 summit. They were also deployed to secure the 2010 Winter Olympics during the Operation Podium.[10] In May 2016, four Griffons were deployed as part of Operation LENTUS 16-01, to provide emergency services for victims of the 2016 Fort McMurray wildfire.[11]

CH-146s have been deployed in Haiti. They were deployed during Operation Standard and Operation Constable between 1996 and 1997.[12][13] They were deployed more recently during Operation Halo in 2004 and Operation Hestia in 2010.

Griffons have been deployed in Bosnia and Kosovo during Operation Kinetic between 1999 and 2000 and Operation Paladium between 1998 and 2004.[14]

In 2007, the Canadian American Strategic Review suggested that the Canadian Forces consider deploying Griffons to Afghanistan, because they were comparable to the UH-1 Hueys deployed by the United States Marine Corps.[15]

On 26 November 2008, the Canadian Forces announced in a statement that eight Griffons would be modified to act as armed escorts for CH-147 Chinook helicopters in Afghanistan.[16][17][18] Equipped with a M134D Minigun, the helicopters were employed in a defensive and support role, including the evacuation of battlefield casualties.[19] The eight CH-146s arrived at Kandahar International Airport on 20 December 2008.[20]

The CH-146 was purchased by the CF to replace four existing helicopters, the CH-136 Kiowa in the observation role, the CH-135 Twin Huey in the army tactical role, the CH-118 Iroquois in the base rescue role and the heavy lift CH-147 Chinook. From the time of its purchase defence analysts have been critical of the aircraft pointing to its procurement as politically motivated and that the aircraft cannot adequately fill any of its intended roles. It has been termed "a civilian designed and built aircraft, with only a coat of green paint."[21][22]

Writing in 2006 defence analyst Sharon Hobson said:

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.[21]

The CH-146 was ruled out for the Afghan mission by General Rick Hillier when he was Chief of Defence Staff in 2008 due to being underpowered. It has also been criticised for being underpowered by Martin Shadwick, a defence analyst and professor at York University. Shadwick stated in July 2009:[23]

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.[23]

At the inquest into the death of Capt Ben Babington-Browne (killed on 6 July 2009 in the crash of aircraft #146434), Lt Cdr William Robley of the UK Defence Helicopter Flying School confirmed that operating the aircraft at that altitude, temperature and weight meant that it was not the correct helicopter for that mission. When asked by the coroner: "Had you been there, would it have been obvious to you of the risks attached to using the Griffon helicopter in these conditions?" Lt Cdr Robley replied: "Yes." When asked: "Would you expect a competent pilot to have understood that this was not the correct helicopter for the mission?", Lt Cdr Robley replied: "It depended on the pilot's training; unless they have been trained, they are on a voyage of discovery."[24]

Retired Lieutenant General Lou Cuppens defended the aircraft's performance:

When the discussions took place about Afghanistan it was very quickly determined that when you do the weather analysis, that the aircraft could not carry the same combat load of troops that it could in Canada and land in a temperate climate. But all you do then is, you use more of them to do the same mission. Looking at operations that we've done elsewhere in the Middle East, with similar aircraft, they all have limitations of some sort and you work with the limitations."[23]

Defence Minister Peter MacKay also defended the aircraft:

I believe the Griffon is a superior helicopter, well-maintained, it's a utility helicopter that serves our interests both in Afghanistan and for purposes here in Canada.[23]
