Bolingbroke assembly line - Fairchild, Longueuil
The wartime need for a patrol bomber led to a Canadian requirement for a bomber that Fairchild Aircraft Ltd. (Canada) of Quebec fulfilled through production of the Bristol Blenheim Mk IV as the Bristol Bolingbroke, irreverently nicknamed the "Bolly." After a small run of aircraft constructed to British specifications, as the Bolingbroke Mk I, Fairchild switched production to the Bolingbroke Mk IV with American instruments and equipment. These versions also included anti-icing boots and a dinghy. Some of these aircraft served as bombers during the Aleutians campaign, but most of the 150 served in the intended role as patrol bombers on the Atlantic coast. Another 450 were completed as the Bolingbroke Mk IVT as trainers and saw extensive use in the Commonwealth Air Training Plan. One of the final variants was the Bolingbroke Mk IVW which was powered by two 895 kW (1,200 hp) Pratt & Whitney R-1830 Twin Wasp engines. In total, 676 Bolingbrokes were produced.
