No. 16 Squadron of the Royal Air Force was formed at St Omer, France on 10 May 1915. It immediately began fighting in World War I under Hugh Dowding, and the squadron would also participate in World War II and the Persian Gulf War. Recently (until March 2005), the unit operated SEPECAT Jaguar GR3s from RAF Coltishall. As 16 (Reserve) Sqn, it was the RAF's Operational Conversion Unit for the Jaguar. The OCU taught pilots how to fly the aircraft and what tactics to use to best exploit the performance of their aircraft and its weapons. The Jaguar is scheduled to be replaced by the Eurofighter Typhoon in RAF service.
