Canadian Armed Forces response to the crash of Stalker 22

On April 29, 2020, six members of the Canadian Armed Forces were killed when a Royal Canadian Air Force CH-148 Cyclone helicopter crashed while conducting maritime surveillance operations. The helicopter was deployed with HMCS Fredericton under Operation REASSURANCE as part of the Standing NATO Maritime Group 2 (SNMG2). At the time of the accident, the Canadian ship was conducting collaborative training with Italian and Turkish ships.


Since 2014, the Canadian Armed Forces (CAF) have deployed a frigate on a persistent rotational basis to be employed for exercises and operational tasks in the NATO Maritime Command’s areas of responsibility.

Her Majesty’s Canadian Ship (HMCS) Fredericton’s deployment is part of a range of military activities undertaken by the CAF under Operation REASSURANCE to support NATO assurance and deterrence measures aimed at reinforcing NATO’s collective defence and strengthening Allied solidarity. These activities include the provision of military capabilities for training, exercises, demonstrations, and assigned NATO tasks, reinforcing Canada’s commitment to promote security and stability in Central and Eastern Europe.

Recovery operation

In the early morning of May 27, 2020, a combined Canadian Armed Forces (CAF) and United States Navy (USN) search and recovery team arrived at the CH-148 Cyclone crash site, which is approximately 220 nautical miles east of Catania, Sicily.
The REMORA III remotely-operated vehicle (ROV) then dove to a depth of 3143 meters and quickly located a large piece of the fuselage. Remains of our fallen CAF personnel were also found in the vicinity of the wreckage.

On June 3rd, 2020, following eight days at the crash site, the decision was made to conclude the recovery operation and return with the discovered remains and multiple pieces of the aircraft that will assist in the ongoing flight safety investigation.

CH-148 Cyclone

CH-148 Cyclone replaced the CH-124 Sea King as Canada’s main ship-borne maritime helicopter, providing air support to the Royal Canadian Navy. This new fleet of aircraft is at the forefront of modern technology and one of the most capable maritime helicopters in the world.

Flight safety investigation

A Flight Safety Investigation into the accident is ongoing.

On June 8, 2020, the Royal Canadian Air Force Directorate of Flight Safety issued its ‘From the Investigator’ report that outlined a focus on aircraft systems and human factors for the continuing investigation.

Immediately-following the accident, the operational airworthiness authority ordered an operational pause on the CH-148 fleet. This pause was put in place as a safety precaution, and resulted in a temporary cessation of flying operations on the Cyclone in order to assess and mitigate potential risks associated with the operation of the aircraft.

On June 16, 2020, the Royal Canadian Air Force lifted the operational pause following a thorough risk assessment that outlined mitigation measures to ensure aircrews understand the conditions that led to the crash and how to avoid or resolve them.
