General Characteristics (Fairchild-Canada Mk IV Variant)

The Bristol Bolingbroke was a Canadian license-built version of the British Bristol Blenheim Mk IV light bomber/maritime patrol aircraft. Built by Fairchild-Canada, it was adapted to meet the Royal Canadian Air Force (RCAF) requirement for a coastal reconnaissance and anti-submarine aircraft. It features a lengthened nose compared to the Blenheim I for improved bombardier space and pilot visibility.
