With a speed of 330 mph, air intercept radar and a one-two punch of cannons and machine guns (or torpedoes or rocket projectiles when engaged in anti-surface duties), the Bristol Beaufighter was one of the Second World War's most formidable night fighters, as well as being the backbone of Coastal Command's anti-shipping war.

Beaufighters were used to attack enemy shipping in the North Sea, the English Channel and in the Mediterranean. Beaufighters were flown in both roles by many Canadians while in RAF service and specifically by No 404, 406, 409, and 410 Sqns in the RCAF. Despite this latter use, the type was never officially "on strength" with the RCAF.
