Peter Jeffrey, was a senior officer and fighter ace in the Royal Australian Air Force (RAAF). Born in Tenterfield, New South Wales, he joined the RAAF active reserve in 1934, and transferred to the Permanent Air Force (PAF) shortly before World War II. Posted to the Middle East in July 1940, Jeffrey saw action with No. 3 Squadron and took command of the unit the following year, earning the Distinguished Flying Cross for his energy and fighting skills. He was appointed wing leader of No. 234 Wing RAF in November 1941, and became an ace the same month with his fifth solo victory. The next month he was awarded the Distinguished Service Order for his achievements, which included rescuing a fellow pilot who had crash landed in the desert.

No. 3 Squadron is a Royal Australian Air Force (RAAF) fighter squadron, headquartered at RAAF Base Williamtown, near Newcastle, New South Wales. Established in 1916, it was one of four combat squadrons of the Australian Flying Corps during World War I, and operated on the Western Front in France before being disbanded in 1919. It was re-established as a permanent squadron of the RAAF in 1925, and during World War II operated in the Mediterranean Theatre. The Cold War years saw the squadron disbanded and re-raised twice. It was based at RAAF Butterworth during the Malayan Emergency and the Indonesia–Malaysia Konfrontasi. Equipped with McDonnell Douglas F/A-18 Hornet multi-role fighters from 1986, the squadron deployed to Diego Garcia in 2002 to provide local air defence, and the following year contributed aircraft and crews to the invasion of Iraq as part of Operation Falconer. In April 2016, it deployed to the Middle East as part of the military intervention against ISIL. The squadron began re-equipping with Lockheed Martin F-35 Lightning II multi-role fighters in 2018.
