Bristol-Fairchild Bolingbroke Mk III. Medium bomber. Manufactured in Canada under license from Bristol.
Bristol-Fairchild Bolingbroke - , manufactured under license in Canada by Fairchild Aircraft Limited under the designation " Bolingbroke ".
Most of the built aircraft in the Mk IV modification served as patrol bombers on the Atlantic and Pacific coasts of Canada from 1940 to 1944. Two squadrons of these aircraft also served in Alaska during the Aleutian campaign.
The disgusting weather in the Aleutian Islands proved to be a worse enemy than the Japanese, and many Bolingbrokes were lost in the thick Alaskan fogs. The usual combat load of the aircraft consisted of three 136-kg depth charges, and two machines were always at the airfield in full readiness for departure. Squadron 8, together with the US Navy, destroyed one Japanese submarine. Bolingbroke, piloted by Flight Sergeant P.M.G. Thomas, attacked and damaged the submarine, after which the arriving warships sent it to the bottom.
Mk IVT trainers have been used extensively in the British Commonwealth Air Training Plan (BCATP).
A total of 626 aircraft were built.
