Vickers-Armstrongs Ltd. of Vickers House, Westminster, London; of Elswick Works, Newcastle-on-Tyne.
1927 The company was formed by the merger of many of the assets of Vickers and Armstrong Whitworth; it was a public company with Vickers the major partner in the new company with two thirds of the shares; Armstrong Whitworth would receive one third of the shares.
The two companies had developed along similar lines, expanded into various military sectors and produced a whole suite of military products. Vickers' assets which would be sold to the new company included those at Sheffield, Barrow, Eskmeals, Erith, Dartford, Swanley and Eynsford. Armstrong's contribution was to be the assets at Elswick, Openshaw and the Naval and Walker shipyards . Some subsidiaries would be retained by the parent companies and operated independently.
1937 Aircraft constructors. 
WWII By the end of 1944 the company had built the King George V battleship and several aircraft carriers at Barrow and Walker. The company also supplied all of the primary armament and much of the fire control gear for all of the battleships and cruisers supplied to the Royal Navy throughout the war. Barrow was the largest maker of submarines supplemented by work done at Walker. The company also manufactured much anti-aircraft equipment. Many land and tracked vehicles were made by the company and the company's designs were also made by outside organisations. On the aviation side, the company developed the Wellington bomber, later used as a transport with the larger variant the Warwick. The Spitfire justly became famous and was produced in many variants. Also some novel, secret weapons developed under the direction of Mr Barnes Wallis. Also many other munitions.
