BAE Systems Heritage traces Hawker Siddeley Aviation to the postwar Hawker Siddeley Group structure, with the aircraft sector operating under the Hawker Siddeley Aviation Limited name after the wider group adopted its 1948 identity. The company absorbed Folland in 1959 and added de Havilland and Blackburn in 1960 during the government-backed rationalization of the UK aircraft industry.
By 1963, the group moved away from separate constituent-company product names and presented new aircraft under the Hawker Siddeley brand. That makes Hawker Siddeley Aviation especially relevant to late-1960s and 1970s aircraft records: the company connected earlier Blackburn, de Havilland, Avro, and Hawker design lines to aircraft families such as the Buccaneer S2, Harrier GR3, Hawk, and Nimrod.
The aviation business ended as an independent manufacturer on 29 April 1977, when Hawker Siddeley Aviation and Hawker Siddeley Dynamics were nationalized and merged with British Aircraft Corporation and Scottish Aviation to form British Aerospace. Its aircraft families then continued through British Aerospace and, later, BAE Systems.

Hawker Siddeley Aviation no longer exists as an independent manufacturer. The aircraft-sector company is distinct from the broader Hawker Siddeley group, and current public sourcing relies on successor-company heritage pages, museum records, and aircraft-family records.
