The Vickers Wellington was a British twin-engined, long range medium bomber designed in the mid-1930s at Brooklands in Weybridge, Surrey, by Vickers-Armstrongs' Chief Designer, Rex Pierson in response to specification B.9/32. Issued in the middle of 1932 this called for a twin-engined day bomber of perceptibly higher performance than any previous designs. It was widely used as a night bomber in the early years of the Second World War, before being displaced as a bomber by the larger four-engined "heavies" such as the Avro Lancaster.
The Wellington continued to serve throughout the war in other duties, particularly as an anti-submarine aircraft. It was the only British bomber to be produced for the entire duration of the war, and was still first-line equipment when the war ended. The Wellington was one of two bombers named after Arthur Wellesley, 1st Duke of Wellington, the other being the Vickers Wellesley.

Design and development
The Wellington used geodesic construction, devised by Barnes Wallis inspired by his work on airships, and previously used to build the single-engined Wellesley light bomber. The fuselage was built from 1650 elements, consisting of aluminium alloy (duralumin) W-beams formed into a framework. Wooden battens screwed to the aluminium were covered with Irish linen, which, treated with layers of dope, formed the outer skin of the aircraft. The metal lattice gave the structure strength, because any one stringer could support some of the weight even from the opposite side of the aircraft. Blowing out one side's beams would still leave the aircraft as a whole intact; as a result, Wellingtons with huge areas of framework missing returned home when other types would not have survived; the dramatic effect was enhanced by the doped fabric skin burning off, leaving the naked frames exposed (see photo).
In one incident, a German Bf 110 night-fighter attacked a Wellington returning from an attack on Münster, Germany, causing a fire at the rear of the starboard engine. Co-pilot Sergeant James Allen Ward climbed out of the fuselage in flight, kicked holes in the doped fabric of the wing for foot and hand holds to reach the starboard engine, and smothered the burning upper wing covering. He and the aircraft returned home safely, and Ward was awarded the Victoria Cross.
The geodesic structure was strong and light for its size, which gave the Wellington a load-and range-to-power-ratio advantage over similar aircraft, without sacrificing robustness or the protection of armour plate or self-sealing fuel tanks. The construction took longer to build than other designs using monocoque construction. It was difficult to cut holes in the fuselage to provide access or equipment fixtures. The Leigh light was deployed through the mounting for the absent FN9 ventral turret. Nonetheless, in the late 1930s Vickers built Wellingtons at one a day at Weybridge and 50 a month at Broughton in North Wales. Peak wartime production in 1942 saw monthly rates of 70 at Weybridge, 130 at Broughton and 102 at Blackpool.
The Wellington was built in 16 variants plus two training conversions after the war. The prototype serial K4049 designed to Ministry Specification B.9/32, first flew as a Type 271 (initially named Crecy) from Brooklands on 15 June 1936, with chief test pilot Joseph Summers as pilot. After many changes to design, it was accepted on 15 August 1936 for production with the name Wellington. The first model was the Wellington Mark I, powered by a pair of 1,050 hp (780 kW) Bristol Pegasus engines, of which 180 were built, 150 for the Royal Air Force and 30 for the Royal New Zealand Air Force (which were transferred to the RAF on the outbreak of war and used by 75 Squadron). The Mark I entered service with No. 9 Squadron RAF in October 1938. Improvements to the turrets resulted in 183 Mark IA Wellingtons, which equipped the RAF Bomber Command heavy bomber squadrons at the outbreak of war. The Wellington was initially outnumbered by its twin-engined contemporaries, the Handley Page Hampden and the Armstrong Whitworth Whitley but outlasted them in service. The number of Wellingtons built totalled 11,461 of all versions, the last rolled out on 13 October 1945. A shadow factory was set up in 1938 especially to make wings for the Wellington Bomber at Trecenydd Caerphilly South Wales operated by Welsh Metal Industries Ltd, now Trecenydd Business Park.
Setting the Assembly Record
As a propaganda and morale-boosting exercise in October 1943, workers at the Broughton factory near Chester gave up their weekend to build Wellington number LN514 rushed by the clock. The bomber was assembled in 23 hours 50 minutes, and took off after 24 hours 48 minutes, beating the record of 48 hours set by a factory in California. The bomber was usually built within 60 hours. The effort was filmed for the Ministry of Information, for a newsreel Worker's Week-End, broadcast in Britain and America.
The first RAF bombing attack of the war was made by Wellingtons of No. 9 and No. 149 Squadron, with Bristol Blenheims, on German shipping at Brunsbüttel on 4 September 1939. During this raid, the two Wellingtons became the first aircraft shot down on the Western Front. Numbers 9, 37 and 149 Squadrons saw action on 18 December 1939 on a mission against German shipping on the Schillig Roads and Wilhelmshaven. Luftwaffe fighters destroyed 12 of the bombers and badly damaged three others, thus highlighting the aircraft's vulnerability to attacking fighters, having neither self-sealing fuel tanks nor sufficient defensive armament. In particular, while the aircraft's nose and tail turrets protected against attacks from the front and rear, the Wellington had no defences against attacks from the beam and above, as it had not been believed that such attacks were possible owing to the high speed of aircraft involved. As a consequence, Wellingtons were switched to night operations and participated in the first night raid on Berlin on 25 August 1940. In the first 1,000-bomber raid on Cologne, on 30 May 1942, 599 out of 1,046 aircraft were Wellingtons (101 of them were flown by Polish aircrews). With Bomber Command, Wellingtons flew 47,409 operations, dropped 41,823 tons (37,941 tonnes) of bombs and lost 1,332 aircraft in action.
Coastal Command Wellingtons carried out anti-submarine duties and sank their first enemy vessel on 6 July 1942. DWI versions (see below) fitted with a 48 ft (14.63 m) diameter metal hoop were used for exploding enemy mines by generating a powerful magnetic field as it passed over them. In 1944, Wellingtons of Coastal Command were deployed to Greece, and performed various support duties during the RAF intervention in the Greek Civil War. A few Wellingtons were operated by the Hellenic Air Force.
While the Wellington was superseded in the European Theatre, it remained in operational service for much of the war in the Middle East and in 1942, Wellingtons based in India became the RAF's first long-range bomber operating in the Far East. It was particularly effective with the South African Air Force in North Africa. This versatile aircraft also served in anti-submarine duties with 26 Squadron SAAF based in Takoradi, Gold Coast (now Ghana).
In late 1944, a radar-equipped Wellington XIV from 407 Sqn. RCAF was modified for use by the RAF's Fighter Interception Unit as what would now be described as an airborne early warning and control aircraft. It operated at an altitude of some 4,000 ft (1,219 m) over the North Sea to control a de Havilland Mosquito and a Bristol Beaufighter fighter intercepting Heinkel He 111 bombers flying from Dutch airbases, and carrying out airborne launches of the V-1 flying bomb. The FIU operators on the Wellington would search for the He-111 aircraft climbing to launch altitude, then direct the Beaufighter to the bomber, while the Mosquito would attempt to intercept the V-1 if launched.
The Wellington is listed in the appendix to the novel KG 200 as one flown by the German secret operations unit KG 200, which also tested, evaluated and sometimes clandestinely operated captured enemy aircraft during the Second World War.

Aircraft on display
- Wellington IA serial number N2980 is on display at Brooklands Museum at Brooklands, Surrey. Built at Brooklands and first flown in November 1939, this aircraft took part in the RAF's daylight bombing raids on Germany early in the Second World War but later lost power during a training flight on 31 December 1940 and ditched in Loch Ness. All the occupants survived except the rear gunner, who was killed when his parachute failed to open. The aircraft was recovered from the bottom of Loch Ness in September 1985 and restored in the late 1980s and 1990s. A new Wellington exhibition around N2980 was officially opened by Robin Holmes (who led the recovery team), Penelope Keith (as trustee of Brooklands Museum), Norman Parker (who worked for Vickers) and Ken Wallis (who flew Wellingtons operationally) on 15 June 2011, the 75th anniversary of the first flight of the type's effective prototype in 1936.
- Wellington T.10 serial number MF628 is held by the Royal Air Force Museum. It was delivered to RAF No.18 MU (Maintenance Unit) for storage at RAF Tinwald Downs, Dumfries, as a Wellington B.X, on 11 May 1944. In March 1948 the front gun turret was removed in its conversion to a T.10 for its role as a postwar aircrew trainer; the RAF Museum later refitted the front gun turret in keeping with its original build as a B.X (wartime mark numbers used Roman numerals, Arabic numerals were adopted postwar). In Autumn 2010, this aircraft was taken to the RAF Museum's site at Cosford for restoration over the next four or five years.

In popular culture
The Wellington was popularly known as the Wimpy by service personnel, after the portly J. Wellington Wimpy character from the Popeye cartoons. Wellington "F for Freddie" appeared in the film Target for Tonight in 1941 and Wellington "B for Bertie" had a starring role in the 1942 Oscar-nominated Powell and Pressburger film One of Our Aircraft Is Missing. James Robertson Justice is sucked out of a hole in the fuselage of a Wellington in Very Important Person (1961) and Terence Rattigan's play Flare Path focuses on the crew of a Wellington before, during and after a bombing raid.
Wellington bomber is also prominent in the 1968 Czechoslovak film "Nebeští jezdci" (Riders in the Sky) about the WW2 Czechoslovak bomber crew flying in the RAF. The film is based on the novel Nebeští jezdci (Sky Riders, 1964) written by Filip Jánský, who was a bomber gunner in the No. 311 Squadron (Czechoslovak) during the war.
The record construction of Vickers Wellington LN514 was documented in the 1943 Worker's Week-End newsreel, and in the 2010 Wellington Bomber documentary. TV Miniseries The Winds of War features the plane during the first raid on Berlin in its fourth episode.
