No. 100 Squadron is a Royal Australian Air Force (RAAF) historic aircraft display squadron. It was originally formed as a bomber and maritime patrol squadron that operated during World War II. Raised in early 1942 from the remnants of a British unit that had been destroyed in Malaya, the squadron flew Bristol Beauforts from bases in Queensland and New Guinea, undertaking torpedo- and level-bombing sorties against Japanese targets in the Pacific theatre. Following the conclusion of hostilities, the squadron was disbanded in August 1946. It was reformed as the Air Force Heritage Squadron in January 2021 to operate airworthy warbirds.
