No. 6 Operational Training Unit (6 OTU) was a Royal Australian Air Force training unit of World War II. 6 OTU was formed at RAAF Base Nowra on 5 June 1943 to provide DAP Beaufort aircrew with training in torpedo dropping procedures and tactics. In late 1943, 6 OTU began moving from Nowra to a nearby airfield at Jervis Bay. By early 1944, however, it was apparent that torpedo use in operations was dropping away. 6 OTU returned to Nowra and was disbanded on 31 March 1944.
