No. 2 Operational Conversion Unit (No. 2 OCU) is a fighter training unit of the Royal Australian Air Force (RAAF). Located at RAAF Base Williamtown, New South Wales, the unit trains pilots to operate the Lockheed Martin F-35 Lightning II. Pilots new to the F-35 enter No. 2 2OCU after first qualifying to fly fast jets at No. 79 Squadron and undertaking initial fighter combat instruction at No. 76 Squadron. Once qualified on the F-35, they are posted to one of No. 81 Wing's operational F-35 units, No. 3 Squadron, No. 75 Squadron or No. 77 Squadron.
The unit was established as No. 2 (Fighter) Operational Training Unit (No. 2 OTU) in April 1942 at Port Pirie, South Australia, and relocated to RAAF Station Mildura, Victoria, the following month. During World War II, it provided training on a wide range of aircraft, including P-40 Kittyhawks, Vultee Vengeances, Avro Ansons, CAC Boomerangs, Supermarine Spitfires and Airspeed Oxfords. Disbanded in March 1947, No. 2 OTU was re-formed at Williamtown in March 1952 in response to the demand for more highly trained pilots to serve in the Korean War. It was renamed No. 2 (Fighter) Operational Conversion Unit in September 1958, and since then has conducted training with the CAC Sabre, Dassault Mirage III, and Macchi MB-326, and the F/A-18 Hornet prior to taking delivery of the F-35s.
