Colin Campbell McMullen, , commonly referred to as C.C. McMullen, was an Australian-born Royal Air Force officer. McMullen was educated in Sydney, and commissioned as an officer in the RAF after moving to the United Kingdom in 1931. During World War II he commanded two flying squadrons, as well as an air station. He continued to serve after the war and was appointed to command a group shortly before his death in 1954.
McMullen moved from Australia to the United Kingdom in 1931 to continue flight training, and received a temporary commission as an officer in the Royal Air Force shortly afterwards. This commission was later made permanent. He placed first in a flying course conducted at RAF Station Grantham in early 1932, and was later trained to operate combat aircraft at RAF Tangmere. On 1 March 1933 a fighter aircraft he was piloting collided with another RAF plane. McMullen escaped with only minor injuries after successfully making an emergency landing, but the pilot of the other aircraft was killed. In January 1939 McMullen was appointed commander of a fighter unit, No. 79 Squadron, and led it following the outbreak of World War II until February 1940. In July 1940 he was mentioned in despatches for "meritorious service with the RAF". In December 1941 McMullen assumed command of No. 109 Squadron, a unit responsible for the development of new technologies. McMullen was responsible for encouraging Don Bennett to try the de Havilland Mosquito, which proved crucial for the effective use of the Oboe target finding device. McMullen was promoted acting wing commander on 11 March 1943, and awarded an Air Force Cross in the 1943 New Year Honours. McMullen was raised to temporary group captain on 21 January 1944. As the commanding officer of RAF Bardney he led the deployment of two squadrons of Avro Lancaster bombers to the Soviet Union in September that year during Operation Paravane, an attack on the German battleship Tirpitz in northern Norway. He also led the deployment of these squadrons to Scotland during the two subsequent attacks on the Tirpitz, Operation Obviate in October and Operation Catechism in November. McMullen was mentioned in despatches again on 1 January 1945. On 1 January 1946 he was appointed a Commander of the Order of the British Empire. McMullen was permanently promoted to the rank of group captain on 22 July 1947. He was raised to air commodore in January 1954, and appointed the commanding officer of No. 81 Group. On 17 February that year he collapsed at Hungerford while driving and subsequently died.
