BRISTOL BEAUFORT

:''Bristol Beaufort was also a car produced by Bristol Cars in the late 1980s and early 1990s.
The 'Bristol Type 152 Beaufort' was a large torpedo bomber designed by the Bristol Aeroplane Company, and developed from the earlier Blenheim light bomber.
Beauforts were most widely used, until the end of the war, by the Royal Australian Air Force in the Pacific theatre. Most of these planes were manufactured under licence in Australia. Beauforts also saw service with the Royal Air Force's Coastal Command—including Commonwealth squadrons serving with the RAF—and then the Fleet Air Arm from 1940, until they were withdrawn in 1944.

Design and development

The Beaufort came from Bristols submission to meet Air Ministry Specifications M.I5/35 and G.24/35 as a land-based twin-engined torpedo-bomber and general reconnaissance aircraft. With a production order to Specification 10/36, the Bristol Type 152 was given the name Bristol Beaufort. ^[1]. the competing torpedo bomber entry from Blackburn, was also ordered as the Blackburn Botha.
Although the design looked similar in most ways to the Blenheim, it was in fact somewhat larger, considerably heavier, and added another crewmember (to make four). The weight proved too much for the Blenheim's Mercury engines, and so a switch to the larger Taurus engine was made. The Taurus proved to be a problem on the Beaufort, and overheating was a constant issue. This introduced delays into the production, so while the plane had first flown in October 1938 and should have been available almost immediately, it was not until December 1939 that production started in earnest, with service entry in August 1940.
A number of changes were introduced into the line, and after the 1014th had been delivered, all of these were collected into the new 'Beaufort Mk.II'. The Mk.II was visibly different primarily in the use of a flat bomb-aiming window under the nose. However it also included a second forward firing 0.303 in (7.7 mm) gun in the wing, a blister under the nose with a rearward firing gun, an improved dorsal turret with a newer Vickers K gun, an installation of the ASV Mk.II air-to-surface radar, removal of the Youngman trailing edges, retractable tailwheel, and improved airflow on some points of the aircraft. Performance, sadly, was not improved.
Oddly the first 165 of the Mk.II's were delivered with the Pratt and Whitney Twin Wasp engines instead of the Taurus. From the 166th onwards engines reverted to the Taurus, although the better performing and more common Twin Wasp seems like a much better fit for the aircraft. The Taurus engine was otherwise unused, and that production line could surely be put to better use.

Australian-built Beauforts

With Britain's domestic aircraft industry working at capacity already in early 1939, the British Air Ministry instigated negotiations to set up parallel production lines in Australia, to supply both the RAF and the RAAF with Beauforts and Twin Wasp engines. Australia's tiny industrial base was barely up to the task of making a modern aircraft, but frantic efforts by the Australian Department of Aircraft Production (DAP) saw the first of an eventual 700 planes roll off the line in August 1941. The Australian made version is often known as the 'DAP Beaufort'.

Operational history

The Beaufort was a slow aircraft, with a top speed of only 265 mph (430 km/h), which dropped to a mere 225 mph (360 km/h) when carrying a torpedo. Although it did see some use in the torpedo bomber role, notably in attacks on the ''Scharnhorst'' and ''Gneisenau'' while in port in Brest, the Beaufort was more often used as a mine-laying aircraft while in European service. It saw considerable action in the Mediterranean theatre, where it helped put an end to Axis shipping supplying Rommel in North Africa.
Coastal Command regarded the Beaufort as a disappointment, but it turned out to make an excellent basis for a heavy fighter in the form of the Bristol Beaufighter. The Beaufighter was so superior to the Beaufort that a number were specially modified to carry a torpedo, and it replaced the Beaufort in service.
During the Pacific War, the Beaufort performed a vital role. With the United States unable to supply many aircraft to the RAAF, the DAP Beaufort became a mainstay of the RAAF during 1941-44. Production continued to increase, reaching almost one a day in 1943. Although inexperience produced a horrendous accident rate early on, the Beaufort served with 19 squadrons and played an important role in the South West Pacific Area, as a maritime patrol and strike aircraft and bomber. Beauforts sunk an impressive tonnage of merchant and naval shipping. After roughly 50 each of the 'Mark V', 'VI' and 'VII' and 520 'Mark VIIIs', production ceased in favour of more modern types in 1944, and handful of VIII's were later modified as transports, known as the 'Mark IX' or "Beaufreighter".
