|The Beaufighter was a home defence night-fighter, also
used for long-range escort-fighter and ground-attack roles, and as anti-shipping
duties. Other roles were bomber, torpedo-carrier and rocket fighter.
It was a two-seater, twin-engine design, with a considerable top speed of 303 m.p.h. and substantial armament which made it a very formidable adversary in its night-fighting role. It started its service in September 1940 with Fighter Command, and by November, radar (airborne interception) equipment had been added for its night-fighter task.
Armament comprised four 20 mm. cannon, and one .303 Browning machine gun.
