History
Armstrong Whitworth Aircraft was originally established as the Aerial Department of the Sir W. G Armstrong Whitworth and Company engineering group in June, 1913 with works in the sawmills at Scotswood, near Newcastle-upon-Tyne. With the advent of contracts from the war office, the aircraft works were moved to premises in nearby Gosforth in September of that year. In 1914 the company produced its first aircraft of original design under the leadership of Dutchman Frederick Koolhoven (b. 11 January 11 1886 - d. 1 July 1946) previously of the British Deperdussin Syndicate, Ltd. Koolhoven left the company in 1917 to join the British Aerial Transport Co, Frank Murphy replacing him as chief designer. Like many other companies, the end of World War One and the resulting termination of aircraft contracts had a serious effect on Armstrong Whitworth and in October of 1919, it was decided to close the Aerial Department.
Meanwhile, in 1906, Captain H.P. Deasy formed the Deasy Motor Car Manufacturing Company in Coventry, and in 1909 John Davenport Siddeley was appointed general manager. By 1912, the company had become the Siddeley Deasy Motor Car Company. During the First World War the company was heavily involved in the production of aero-engines and in 1917 an aeroplane design office was opened under the leadership of John Lloyd.
Late in 1918, Armstrong Whitworth were approached by J.D. Siddeley about the possibility of a link up between the two firms and, in 1919, Armstrong Whitworth acquired Siddeley Deasy and formed the Armstrong Whitworth Development Company. The engine and automotive businesses of both companies were spun off as Armstrong Siddeley Motors Limited and in 1920 the aircraft interests became a separate company known as the Sir W. G. Armstrong Whitworth Aircraft Company, centered at the old Siddeley Deasy factory in Parkside, near Coventry. Later that year, Armstrong Whitworth acquired a former RAF airfield at Whitley, south of Coventry, the works moving there in 1923 although the design office remained at Parkside until 1930. During 1925/6, the main Armstrong Whitworth concern in Newcastle was suffering from the economic downturn and was largely supported by the aircraft division. J. D. Siddeley bought the aircraft division in December 1926 and in 1927 the name of the Armstrong Whitworth Development Company was changed to the Armstrong Siddeley Development Company. The same year, Vickers and Armstrong Whitworth merged to form Vickers-Armstrongs.
In 1928, Armstrong Siddeley Holdings Ltd acquired A.V.Roe and Co Ltd. Siddeley had formed a flying school at Whitley in 1920 and in 1931, this developed into the wholly owned subsidiary Air Service Training (AST). With the acquisition of A.V. Roe, AST moved to Roe's Hamble facility. AST eventually became an independent company within the Hawker Siddeley Group in 1940.
In 1935, J. D. Siddeley retired and Armstrong Whitworth Aircraft was purchased by Hawker Aircraft, the new group becoming Hawker Siddeley Aircraft. The component companies of Hawker Siddeley co-operated, but operated as individual entities. The same year, with the growing size of Armstrong Whitworths' products, the Whitley airfield was proving too small and a new factory was established at the municipal aerodrome at nearby Bagington. Both factories continued in use throughout World War Two, but with the wholesale cancellation of contracts following the end of the war, all production was centered on Bagington and Whitley was closed.
Production at Armstrong Whitworth post war largely centered on manufacture for other members of the Hawker Siddeley Group, and the building of high speed aircraft showed the limitations of Bagington. As a result, the company leased two hangars at Bitteswell, near Lutterworth in Leicestershire in 1952, finally purchasing the airfield outright in 1956.
Armstrong Whitworth Aircraft was eventually merged with another Hawker Siddeley company, the Gloster Aircraft Company, in October, 1961, the combined companies being known as Whitworth Gloster Aircraft Ltd. On 1 July 1963 the company again merged with another Hawker Siddeley company, this time Avro and, with Hawker Siddeley dropping the names of the component companies from its products, became the Avro Whitworth Division of Hawker Siddeley Aviation, the last Armstrong Whitworth Design, the A.W.681 transport, now becoming the H.S.681. The government axing of many major programs in 1965, including the H.S.681, finally brought about the closure of Bagington in July, 1965. Bitteswell soldiered on until 1983 as an overhaul and repair facility until 1983, when it too finally closed.

Armstrong Whitworth Designations
The Type Designation system for the Aerial Department of the Sir W. G Armstrong Whitworth and Company was based on designers’ name. The first aircraft were in the F.K. series, after their designer, Frederick Koolhoven. Following the departure of Koolhoven, the next aircraft were in the F.M. series, after their designer, Frank Murphy. The allocation of F.M.1 to F.M.3, if any, is unknown.
The Siddeley Deasy Company’s first designs appear to use a role based Type Designation, similar to that of the Royal Aircraft Factory designs from which they were derived.
After the amalgamation of the two companies, Armstrong Whitworth eventually settled on a simple and logical alpha-numeric Type Designation system, although the first use that is identified is the A.W.XIV. What, if anything, the A.W.I through A.W.XIII were is unknown. Although originally using Roman numerals, these quickly changed to Arabic.

Project Notes
- Incorrectly identified in Tapper [1] as F.K.3.
- Incorrectly identified in Lewis [3], Mason [5], Bruce [7 and 34] and Gunston [30] as F.K.12 - see Tapper [1].
- To OR.9, OR.11 and OR.20.
- The F.K.11 is the last positively identified Koolhoven design for Armstrong Whitworth. It is speculated that the F.K.12 may have been the "Improved F.K.8" and F.K.13 the Fleet Fighter Reconnaissance Biplane. In 1926, Koolhoven retroactively applied F.K. designations to his earlier work and that included F.K.14 to F.K.19 (F.K.20 being his first design for BAT), but there is no evidence to tie these to Armstrong Whitworth.
A list of Koolhovens designs (in Dutch) may be found at http://www.hdekker.info/DIVERSEN/Koolhoven.htm - This number was used for gondolas for the ten Submarine Scout airships that Armstrong Whitworth built (S.S.40 - S.S.49) and was based on an F.K.3 fuselage. Since the contract stipulated that a reserve for each airship hull was needed, it is entirely possible that twenty of these F.K. 4 hulls were built.
- Williams [358] indicates this to be to Specification C.5/44, which was for the Handley Page Hermes, but it is too small.
- Payne [29] indicates these two submissions to the Brabazon Committee requirements, but there is nothing to suggest that AW were ever invited to tender to any Type requirement.
