Originally created as heavy long-range night fighters, the later Bristol Beaufighters were used as bombers and torpedo bombers. The last major modification, the Beaufighter TF Mk.X, was considered one of the finest torpedo bombers of the time.
The Beaufighter aircraft series was the first with a radar system, allowing it to participate effectively in night operations.
In 1944, after Australia’s aircraft manufacturing contract expired, Beaufort’s Department of Aircraft Production was commissioned to build 500 aircraft based on the Beaufighter Mk.X. The Australian version of the aircraft was named the Beaufighter Mk.21 and differed from its predecessor in its nose cone, the replacement of the 7.69mm machine guns with Browning M2 12.7mm guns, and the replacement of its Hercules XVII engine with a Hercules CVII (1600 hp).
But only 364 of these aircraft were built, since the war ended before completion of the first order and the rest of the torpedo bombers production was cancelled.
