The Armstrong Whitworth A.W.38 Whitley was one of three British twin-engined, front line medium bomber types that were in service with the Royal Air Force
Royal Air Force
(RAF) at the outbreak of the Second World War. Alongside the Vickers Wellington

and the Handley Page Hampden, the Whitley was developed during the mid-1930s according to Air Ministry Specification B.3/34, which it was subsequently selected to meet. In 1937, the Whitley formally entered into RAF squadron service; it was the first of the three medium bombers to be introduced. Following the outbreak of war in September 1939, the Whitley participated in the first RAF bombing raid upon German territory and remained an integral part of the early British bomber offensive. By 1943, it was being superseded as a bomber by the larger four-engined "heavies" such as the Avro Lancaster.[2] Its front line service included maritime reconnaissance with Coastal Command
Coastal Command
and the second line roles of glider-tug, trainer and transport aircraft. The type was also procured by British Overseas Airways Corporation
British Overseas Airways Corporation
(BOAC) as a civilian freighter aircraft. The aircraft was named after Whitley, a suburb of Coventry, home of one of Armstrong Whitworth's plants.

In July 1934, the Air Ministry
Air Ministry
issued Specification B.3/34, seeking a heavy night bomber/troop transport to replace the Handley Page Heyford biplane bomber.[3] John Lloyd, the Chief Designer of Armstrong Whitworth Aircraft, chose to respond to the specification with a design designated as the AW.38, which later was given the name Whitley after the location of Armstrong Whitworth's main factory. The design of the AW.38 was in fact a development of the Armstrong Whitworth AW.23 bomber-transport design that had lost to the Bristol Bombay
Bristol Bombay
for the earlier Specification C.26/31.[3] Lloyd selected the Armstrong Siddeley Tiger
Armstrong Siddeley Tiger
IX radial engine to power the Whitley, which was capable of generating 795 horsepower.[3] One of the more innovative features of the Whitley's design was the adoption of a three-bladed two-position variable-pitch propeller built by de Havilland; the Whitley was the first aircraft to fly with such an arrangement.[3] As Lloyd was unfamiliar with the use of flaps on a large heavy monoplane, they were initially omitted from the design. To compensate, the mid-set wings were set at a high angle of incidence (8.5°) to confer good take-off and landing performance.[4] Although flaps were included late in the design stage, the wing remained unaltered; as a result, the Whitley flew with a pronounced nose-down attitude when flown with the wings in the cruising position, resulting in considerable drag.[4][5] The Whitley holds the distinction of having been the first aircraft to serve with the RAF to utilise a semi-monocoque fuselage, which was built using a slab-sided structure to ease production.[2] This replaced the traditional tubular construction method previously employed by Armstrong Whitworth, instead constructing the airframe from light-alloy rolled sections, pressings, and corrugated sheets.[3] According to aviation author Philip Moyes, the decision to adopt the semi-monocoque fuselage design was a significant step forwards, and the integrity of which was well-proven during subsequent RAF service, having survived multiple instances of severe damage being sustained.[3] On June 1935, owing to the urgent need to replace biplane heavy bombers then in service with the RAF, a verbal agreement was formed to produce an initial 80 aircraft, 40 being of an early Whitley Mk I standard and the other 40 being a more advanced Whitley Mk II standard.[4] Production was initially at three factories in Coventry; fuselages and detailed components were fabricated at Whitley Abbey, panel-beating and much of the detailed work occurred at the former Coventry
Coventry
Ordnance Works facility, while wing fabrication and final assembly took placed at Baginton Aerodrome.[4] During 1935 and 1936, various contracts were placed for the type; the Whitley was ordered "off the drawing board" - prior to the first flights of any of the prototypes.[4] On 17 March 1936, the first prototype Whitley Mk I, K4586, conducted its maiden flight from Baginton Aerodrome, piloted by Armstrong Whitworth Chief Test Pilot Alan Campbell-Orde.[6] K4586 was powered by a pair of 795 hp (593 kW) Tiger IX engines. The second prototype, K4587, was furnished with a pair of more powerful medium-supercharged Tiger XI engines.[7][6] The prototypes differed little from the initial production standard aircraft; a total of 34 production Whitley Mk I were completed.[6] Further development[edit] After the first 34 aircraft had been completed, the engines were replaced with the more reliable two-speed-supercharged Tiger VIIIs. K7243, the 27th production Whitley, is believed to have served as a prototype following modifications.[6] The resulting aircraft was designated as the Whitley Mk II. A total of 46 production aircraft were completed to the Whitley Mk II standard.[6] One Whitley Mk II, K7243, was used as a test bed for the 1,200 hp 21-cylinder radial Armstrong Siddeley Deerhound
Armstrong Siddeley Deerhound
engine; on 6 January 1939, K7243 made its first flight with the Deerhound.[8][9] Another Whitley Mk I, K7208, was modified to operate with a higher (33,500 lb) gross weight.[10] K7211, the 29th production Whitley, served as the prototype for a further advanced variant of the aircraft, the Whitley Mk III.[6] The Whitley Mk III featured numerous improvements, such as the replacement of the manually operated nose turret with a powered Nash & Thompson turret and a powered retractable twin-gun ventral "dustbin" turret. The ventral turret was hydraulically-powered but proved to be hard to operate and added considerable drag, thus the Whitley Mk III was the only variant to feature this ventral turret arrangement.[6] Other changes included increased dihedreal of the outer wing panels, superior navigational provisions, and the installation of new bomb racks.[11] A total of 80 Whitley Mk III aircraft were manufactured.[6] While the Tiger VIII engine used in the Whitley Mks II and III was more reliable than those used in early aircraft, the Whitley was re-engined with Rolls-Royce Merlin
Rolls-Royce Merlin
engines in 1938, giving rise to the Whitley Mk IV.[12] Three Whitley Mk I aircraft, K7208, K7209, and K7211, were initially re-engined to serve as prototypes. The new engines are accredited with producing greatly improved performance.[2][12] Other changes made included the replacement of the manually operated tail and retractable ventral turrets with a Nash & Thompson powered turret equipped with four .303 in (7.7 mm) Browning machine guns, the increasing of fuel tankage capacity, including two additional fuel tanks in the wing.[12] A total of 40 Whitley Mk IV and Whitley Mk IVA, a sub-variant featuring more powerful models of the Merlin engine, were completed.[12] The decision was made to introduce a series of other minor improvements to produce the Whitley Mk V. These included the modification of the tail fins and rudders, the fitting of leading edge de-icers, further fuel capacity increases, a smaller D/F loop in a streamlined fairing being adopted, and the extension of the rear fuselage by 15 in (381 mm) to improve the rear-gunner's field of fire.[13] The Whitley Mk V was by far the most numerous version of the aircraft, with 1,466 built until production ended in June 1943.[2][13] The Whitley Mk VII was the final variant to be built. Unlike the other variants, it was developed for service with RAF Coastal Command
RAF Coastal Command
and was thus furnished for maritime reconnaissance rather than as a general purpose bomber.[13] A single Whitley Mk V, P3949 acted as a prototype for this variant. A total of 146 Whitley Mk VIIs would be produced, additional Whitley Mk V aircraft would be converted to the standard as well.[13] It had a sixth crew member to operate the new ASV Mk 2 radar system along with an increased fuel capacity for long endurance anti-shipping missions.[14] Some Whitley Mk VII were later converted as trainer aircraft, featuring additional seating and instrumentation for flight engineers.[10] Early marks of the Whitley featured bomb bay doors, fitted on both the fuselage and wing bays, that were held shut by bungee cords; during bombing operations, these were opened by the weight of the bombs as they fell on them and closed again by the bungee cord.[4][5] The short and unpredictable delay for the doors to open led to highly inaccurate bombing. The Mk.III introduced hydraulically actuated doors which greatly improved bombing accuracy. To aim bombs, the bomb aimer opened a hatch in the nose of the aircraft, which extended the bomb sight out of the fuselage but the Mk IV replaced this hatch with a slightly extended transparent plexiglas panel, improving crew comfort.[12][15] Design[edit]

The Armstrong Whitworth Whitley
Armstrong Whitworth Whitley
was a twin-engined heavy bomber, initially being powered by a pair of 795 h.p. Armstrong Siddeley Tiger IX radial engines.[16] More advanced models of the Tiger engine equipped some of the later variants of the Whitley; starting with the Whitley Mk IV variant, the Tigers were replaced by a pair of 1,030 h.p. Rolls-Royce Merlin
Rolls-Royce Merlin
IV V12 engines.[11] According to Moyes, the adoption of the Merlin engine gave the Whitley a considerable boost in performance.[12] The Whitley had a crew of five: a pilot, co-pilot/navigator, a bomb aimer, a wireless operator and a rear gunner. The pilot and second pilot/navigator sat side by side in the cockpit, with the wireless operator further back. The navigator rotated to use the chart table behind him. The bomb aimer position was in the nose with a gun turret located directly above. The fuselage aft of the wireless operator was divided horizontally by the bomb bay; behind the bomb bay was the main entrance and aft of that the rear turret.[15] The offensive armaments were stowed in two bomb bays housed within the fuselage, along with a further 14 smaller cells in the wing.[4] Bomb racks capable of holding larger bombs were installed on the Whitley Mk III variant.[6] The early examples had a nose turret and rear turret, both being manually operated and mounting one Vickers 0.303 machine gun. On the Whitley Mk III this arrangement was substantially revised: a new retractable ventral 'dustbin' position was installed mounting twin .303 in (7.7 mm) Browning machine guns and the nose turret was also upgraded to a Nash & Thompson power-operated turret.[6] On the Whitley Mk IV, the tail and ventral turrets were replaced with a Nash & Thompson power-operated turret mounting four Browning machine guns; upon the adoption of this turret arrangement, the Whitley became the most powerfully armed bomber in the world against attacks from the rear.[12]

The fuselage comprised three sections, with the main frames being riveted with the skin and the intermediate sections being riveted to the inside flanges of the longitudinal stringers.[3] Extensive use of Alclad sheeting was made. Fuel was carried within total of three tanks, a pair of 182 gallon tanks contained within each wing and one 15 gallon tank in the roof of the fuselage; two auxiliary fuel tanks could be installed in the front fuselage bomb bay compartment.[4] To ease production, a deliberate effort was made to reduce component count and standardise parts.[3] The fuselage proved to be robust enough to withstand severe damage.[4] The Whitley featured a large rectangular-shaped wing; its appearance led to the aircraft receiving the nickname "the flying barn door".[4] Like the fuselage, the wings were formed from three sections, being built up around a box spar with the leading and trailing edges being fixed onto the spar at each rib point.[17] The surfaces of the wings were mainly composed of flush-riveted, smooth and unstressed metal sheeting and the trailing edge and ailerons had a fabric covering.[17] The split trailing edge flaps were composed of duralumin and ran between the ailerons and the fuselage, being set at a 15–20 degree position for taking off and at a 60 degree position during landing.[4] The tailplanes employed a similar construction to that of the wings, the fins being braced to the fuselage using metal struts the elevators and rudders incorporated servo-balancing trim tabs.[4] Operational history[edit] Military service[edit]

Whitley Mk.V production, 1941

On 9 March 1937, the Whitley Mk I began entering squadron service with No. 10 Squadron of the RAF, replacing their Handley Page Heyford biplanes.[18][19] In January 1938, the Whitley Mk II first entered squadron service with No. 58 Squadron and in August 1938, the Whitley Mk III first entered service with No. 51 Squadron.[19] In May 1939, the Whitley Mk IV first entered service with No. 10 Squadron and in August 1939, the Whitley Mk IVA first entered service with No. 78 Squadron.[19] By the outbreak of the Second World War, a total of seven squadrons were operational, the majority of these flying Whitley III or IV aircraft, while the Whitley V had only just been introduced to service; a total of 196 Whitleys were on charge with the RAF.[18][19][20] At the start of the war, No. 4 Group, equipped with the Whitley, held the distinction of being the only trained night bomber force in the world.[19] Alongside the Handley Page Hampden
Handley Page Hampden
and the Vickers Wellington, the Whitley bore the brunt of the early fighting and saw action during the first night of the war, when they dropped propaganda leaflets over Germany.[21] The propaganda flight made the Whitley the first aircraft of RAF Bomber Command
RAF Bomber Command
to penetrate into Germany.[19] Further propaganda flights would travel as far as Berlin, Prague, and Warsaw.[22] On the night of 19/20 March 1940, in conjunction with multiple Hampdens, the Whitley conducted the first bombing raid on German soil, attacking the Hörnum
Hörnum
seaplane base on the Island of Sylt.[2][23] Following the Hörnum
Hörnum
raid, Whitleys routinely patrolled the Frisian Islands, targeting shipping and seaplane activity.[19] On the night of 11/12 June 1940, the Whitley carried out Operation Haddock, the first RAF bombing raid on Italy, only a few hours after Italy's declaration of war; the Whitleys bombed Turin
Turin
and Genoa, reaching Northern Italy via a refuelling stop in the Channel Islands.[21][23] Many leading World War II
World War II
bomber pilots of the RAF flew Whitleys at some point in their career, including Don Bennett, James Brian Tait, and Leonard Cheshire.[24]

Unlike the Hampden and Wellington, which had met Specification B.9/32 for a day bomber, the Whitley was always intended for night operations alone and thus escaped the early heavy losses received during daylight raids carried out upon German shipping.[3] As the oldest of the three bombers, the Whitley was effectively obsolete by the start of the war, yet over 1,000 more aircraft were produced before a suitable replacement was found. A particular problem with the twin-engine aircraft was that it could not maintain altitude on one engine. Whitleys flew a total of 8,996 operations with Bomber Command, dropped 9,845 tons (8,931 tonnes) of bombs, and 269 aircraft were lost in action.[25] On the night of 29/30 April 1942 No. 58 Squadron flying Whitleys bombed the Port of Ostend in Belgium. This was the last operational mission by a Whitley equipped bomber squadron.[26] In late 1942, the Whitley was retired from service as a frontline aircraft for bomber squadrons and was shifted to other roles. The type continued to operate delivering supplies and agents in the Special
Special
Duties squadrons (138 and 161) until December 1942, as well as serving as a transport for troops and freight, a carrier for paratroopers and a tow aircraft for gliders.[27] In 1940, the Whitley had been selected as the standard paratroop transport; in this role, the ventral turret aperture was commonly modified to be used for the egress of paratroopers.[26] No. 100 Group RAF
No. 100 Group RAF
used Whitleys as an airborne platform to carry airborne radar and electronic counter-measures. In February 1942, Whitleys were used to carry the paratroopers who participated in the Bruneval
Bruneval
raid, code named Operation Biting, in which German radar technology was captured from a German base on the coast of France.[27] Long-range Coastal Command
Coastal Command
Mk VII variants, were among the last Whitleys remaining in front-line service, remaining in service until early 1943.[26] The first U-boat
U-boat
kill attributed to the Whitley Mk VII was the sinking of the German submarine U-751 on 17 July 1942, which was achieved in combination with a Lancaster heavy bomber.[28][29] Having evaluated the Whitley in 1942, the Fleet Air Arm operated a number of modified ex-RAF Mk VIIs from 1944 to 1946, to train aircrew in Merlin engine management and fuel transfer procedures.[2] Civilian service[edit] In April/May 1942, the British Overseas Airways Corporation
British Overseas Airways Corporation
(BOAC) operated 15 Whitley Mk V aircraft which had been converted into freighters. The conversion process involved the removal of all armaments, the turret recesses were faired over, additional fuel tanks were installed in the bomb bay, the interior of the fuselage was adapted for freight stowage, and at least one aircraft was fitted with an enlarged cargo door.[19] The type was typically used for night supply flights from Gibraltar
Gibraltar
to Malta; the route took seven hours, and would often require landing during Axis air attacks on the island.[30] Whitley freighters also flew the dangerous route between Leuchars Station, Scotland
Scotland
and Stockholm, Sweden.[19] The Whitley consumed a proportionally large quantity of fuel to carry a relatively small payload, and there were various other reasons making the type less than ideal, so in August 1942 the type was replaced by the Lockheed Hudson
Lockheed Hudson
and the 14 survivors were returned to the RAF.[19][30]
