The Whitley would serve with Bomber Command and Coastal Command during the early years of World War 2 and was used in 'Operation Biting' to help capture German radar. Used for special operations at RAF Tempsford the Armstrong Whitworth Whitley would also be used by British Overseas Airways Corporation.

During the early to mid 1930s the Royal Air Force was heavily reliant on bi-plane aircraft and was urgently trying to modernise its aircraft. So with the issuing in July 1934 of Specification B.3/34 the Air Ministry were looking for a twin-engined heavy night bomber. Armstrong Whitworth's submission to this specification would be led by the company's chief designer John Lloyd. With design work in progress the need for more modern aircraft within the RAF was shown by an order for 80 Whitleys being placed seven months before the prototype flew.

The prototype would be ready for its maiden flight on the 17th March 1936 at Whitley Abbey with Alan Campbell-Orde at the controls, with power supplied by a pair of Armstrong Siddeley Tiger X engines. Its monocoque structure was made of light alloy, which saw Armstrong Whitworth move away from their usual steel tube construction. Trials of the Royal Air Force's new bomber were done in Autumn 1936 at Martlehsam Heath by the Aircraft and Armament Experimental Establishment. A second prototype would have a specially written specification for it, B.21/35, and this made its maiden flight on the 24th February 1937, powered by the Tiger XI engine, and was flown by Charles Turner Hughes.

The Whitley would enter service during March 1937 with No. 10 Squadron based at Dishforth receiving their first Mk Is on the 9th, to replace their Handley Page Heyford aircraft. Able to house a crew of upto 5, armament would consist of a single 0.303-in Vickers machine-gun in nose and tail turrets which were manually operated and designed by Armstrong Whitworth. Of the original order of 80, 34 would be Mk Is whilst the rest would be Mk Iis which were powered by Tiger VIII engines which featured a two-speed supercharger. A further order for 80 Whitleys was placed and these would be the Mk III. The armament on this new variant was upgraded, firstly the bomb-bay was changed to allow larger bombs to be carried, the nose turret was changed to a Nash and Thompson turret which was power operated and two more machine-guns in the form of 0.303-in Brownings were added to a new retractable turret underneath the fuselage.

Flying from Hucknall on the 11th February 1938 a Whitly Mk I was tested with Rolls-Royce Merlin IIs, however the programme was suspended after the second flight which had to be curtailed due to engine failure. After the test programme was resumed the aircraft was sent to the A&AEE at Martlesham Heath for further tests during April and May.

The next production version, which first flew on the 5th April 1939, was the Mk IV which featured a number of changes. The first change saw the aircraft now powered by the 1,030-hp Rolls-Royce Merlin IV engine. The second change saw a pair of wing tanks added whilst other changes included improvements to the bomb-aimers view with the addition in the lower nose of a clear panel. The armament for the rear gunner was also upgraded to four 0.303-in Browing guns in a Nash and Thompson power-operated turret. Powered by the 1,145-hp Merlin X seven Whitley Mk IVAs were produced alongside 26 Mk IVs.

Futher changes to the design saw the Whitley Mk V appear which was to be the most produced version and would also be powered by Merlin engines. Once again fuel capacity was improved and extra fuel could be carried in the bomb-bay if needed. On the leading edges of the wings rubber de-icer boots were added. The rear of the aircraft was also re-designed to increase the rear gunner's field of fire, this would see the rear fuselage lengthened 1ft 3in. The fins was also given straight leading edges. In total 1,466 Mk Vs were built.

With the Rolls-Royce Merlin in demand for use in a number of aircraft a Pratt & Whitney powered Whitley Mk VI was considered in case Merlin engines became unavailable. In the end this proposed aircraft would never go into production. Based on the Mk V the Whitley Mk VII was designed for operational service with Coastal Command. This would see the installation of ASV Mk II air-to-service radar and the fitting in the rear of the fuselage and bomb-bay of additional fuel tanks. A total of 146 would be built.

Armstrong Whitworth Whitleys were in action with Bomber Command on the same day as Britain and France declared war on Germany, 3rd September 1939, when 10 aircraft flew over Bremen, Hamburg and the Ruhr dropping leaflets. Whitleys would also take part in the first raid on Berlin on the 25th August 1940 alongside the Handley Page Hampden and Vickers Wellington. The type would also be called on the day after Italy declared war on Britain and France when on the 11th June 1940 raids were carried out on Genoa and Turin. However of the 36 aircraft that took part only 13, 36% of the total force, reached their target as both engine problems and weather hampered the operation.

With the Short Stirling and Handley Page Halifax four-engined bombers now in service and with the Avro Lancaster entering service the Whitley's time in Bomber Command was coming to an end. Its last official sortie took place on the 29th April 1942 with a raid on Ostend. However Whitleys from operational training units would take part in the raid on Cologne on the 30th May that year in the first ever '1,000 Bomber' attack.

The Whitley would also serve with Coastal Command and its service with the Command began when No. 58 Squadron were seconded in September 1939. This would see them patrol over the English Channel until February 1940 when they operated as part of Bomber Command again. Other Whitley squadrons would also patrol over the Bay of Biscay. It would take over 2 years before the type scored its first U-boat victory when on the 30th November 1941 No. 502 Squadron sank U-205 in the Bay of Biscay.

The type would also be used for a number of special operations. This included 'Operation Biting' on the 27th February 1942 which saw them drop paratroopers at Bruneval in Northern France for what was a successful mission to capture parts of German radar. Two squadrons, Nos. 138 and 161, would also serve at RAF Tempsford undertaking 'special duties'. This involved supplying arms and equipment to the Resistance and transport agents by parachute drop into occupied countries. Other duties for the Whitley saw it used as a glider tug and for parachute training. During May 1942 the British Overseas Airways Corporation received 15 Mk Vs which had their armament removed and fuel tanks added to the bomb-bays. These would be used by BOAC on their Gibraltar to Malta route.

By the time the last Armstrong Whitworth Whitley rolled of the production line a total of 1,814 had been built.
