The Bristol Fairchild Bolingbroke is a maritime patrol aircraft and trainer used by the Royal Canadian Air Force during the Second World War.

Produced by Fairchild-Canada, it was a license-built version of the Bristol Blenheim Mk IV bomber.

In 1935, the British Air Ministry issued Specification G.24/35 to procure a coastal reconnaissance/light bomber to replace the Avro Anson.

[5] Most of the 151 Mk IVs built served in their intended role as patrol bombers on the Atlantic and Pacific coasts of Canada between 1940 and 1944.

[6] The Mk IVT trainers saw extensive use in the British Commonwealth Air Training Plan (BCATP).
