Number 22 Squadron of the Royal Air Force is an operational testing and evaluation squadron for all the Joint Helicopter Command helicopter types including Chinook, Puma HC2, Merlin HC4, Apache and Wildcat AH1. Formerly the Rotary Wing Operational Evaluation and Training Unit, the highly experienced helicopter aircrew will also ensure frontline crews have Qualified Warfare Instructors to support them on operations worldwide. The squadron was reformed in May 2020 to serve as the Joint Helicopter Command Operational Evaluation Unit. The squadron previously operated the Westland Sea King HAR.3 and HAR.3A at three stations in the southern United Kingdom. It was originally formed in 1915 as an aerial reconnaissance unit of the Royal Flying Corps serving on the Western Front during the First World War.
