|William George Armstrong Founder|
Sir W G Armstrong Whitworth & Co Ltd was a major British manufacturing company of the early years of the 20th century. With headquarters in Elswick, Newcastle upon Tyne, Armstrong Whitworth engaged in the construction of armaments, ships, locomotives, automobiles, and aircraft.
In 1847, engineer William George Armstrong founded the Elswick works at Newcastle, to produce hydraulic machinery, cranes and bridges, soon to be followed by artillery, notably the Armstrong breech-loading gun, which re-equipped the British Army after the Crimean War. In 1882, it merged with the shipbuilding firm of Charles Mitchell to form Armstrong Mitchell & Company and at the time its works extended for over a mile (about 2 km) along the bank of the River Tyne. Armstrong Mitchell merged again with the engineering firm of Joseph Whitworth in 1897. The company expanded into the manufacture of cars and trucks in 1902, and created an "aerial department" in 1913, which became the Armstrong Whitworth Aircraft subsidiary in 1920.
The Armstrong-Whitworth was manufactured from 1904 (when the company took over construction of the Wilson-Pilcher designed by Walter Gordon Wilson) until 1919 (when the company merged with Siddeley-Deasy and began construction of the Armstrong Siddeley) in Coventry.
The Wilson-Pilcher was an advanced car, originally with a 2.4-litre engine, that had been made in London from 1901 until 1904 when production moved to Newcastle. When Armstrong-Whitworth took over production two models were made, a 2.7-litre flat four and a 4.1-litre flat six, the cylinders on both being identical with bore and stroke of 3.75in (95mm). The engines had the flywheel at the front of the engine, and the crankshaft had intermediate bearings between each pair of cylinders. Drive was to the rear wheels via a preselector gearbox and helical bevel axle. The cars were listed at £735 for the four and £900 for the six. They were still theoretically available until 1907. According to Automotor in 1904 "Even the first Wilson-Pilcher car that made its appearance created quite a sensation in automobile circles at the time on account of its remarkably silent and smooth running, and of the almost total absence of vibration".
The first Armstrong-Whitworth car was the 28/36 of 1906 with a water-cooled, four-cylinder side-valve engine of 4.5 litres which unusually had "oversquare" dimensions of 120 mm (4.7 in) bore and 100 mm (3.9 in) stroke. Drive was via a four-speed gearbox and shaft to the rear wheels. A larger car was listed for 1908 with a choice of either 5-litre 30 or 7.6-litre 40 models sharing a 127 mm (5.0 in) bore but with strokes of 100 mm (3.9 in) and 152 mm (6.0 in) respectively. The 40 was listed at £798 in bare chassis form for supplying to coachbuilders. These large cars were joined in 1909 by the 4.3-litre 18/22 and in 1910 by the 3.7-litre 25, which seems to have shared the same chassis as the 30 and 40.
In 1911, a new small car appeared in the shape of the 2.4-litre 12/14, called the 15.9 in 1911, featuring a monobloc engine with pressure lubrication to the crankshaft bearings. This model had an 88-inch (2,200 mm) wheelbase compared with the 120 inches (3,000 mm) of the 40 range. This was joined by four larger cars ranging from the 2.7-litre 15/20 to the 3.7-litre 25.5.
The first six-cylinder model, the 30/50 with 5.1-litre 90 mm (3.5 in) bore by 135 mm (5.3 in) stroke engine came in 1912 with the option of electric lighting. This grew to 5.7 litres in 1913.
At the outbreak of war, as well as the 30/50, the range consisted of the 3-litre 17/25 and the 3.8-litre 30/40.
The cars were usually if not always bodied by external coach builders and had a reputation for reliability and solid workmanship. The company maintained a London sales outlet at New Bond Street. When Armstrong Whitworth and Vickers merged, Armstrong Whitworth's automotive interests were purchased by J. D. Siddeley as Armstrong Siddeley.
Armstrong Whitworth established an Aerial Department in 1912. This later became the Sir W. G. Armstrong Whitworth Aircraft Company. When Vickers and Armstrong Whitworth merged in 1927 to form Vickers-Armstrongs, Armstrong Whitworth Aircraft was bought out by J. D. Siddeley and became a separate entity.
The Elswick Ordnance Company (sometimes referred to as Elswick Ordnance Works, but usually as "EOC") was originally created in 1859 to separate William Armstrong's armaments business from his other business interests, to avoid a conflict of interest as Armstrong was then Engineer of Rifled Ordnance for the War Office and the company's main customer was the British Government. Armstrong held no financial interest in the company until 1864 when he left Government service, and Elswick Ordnance was re-united with the main Armstrong businesses to form Sir W.G. Armstrong & Company. EOC was then the armaments branch of W.G. Armstrong & Company and later of Armstrong Whitworth.
Elswick Ordnance was a major arms developer before and during World War I. The ordnance and ammunition it manufactured for the British Government were stamped EOC, while guns made for export were usually marked "W.G. Armstrong".
After the Great War, Armstrong Whitworth converted its Scotswood Works to build railway locomotives. From 1919 it rapidly penetrated the locomotive market due to its modern plant. Its two largest contacts were 200 2-8-0’s for the Belgian State Railways in 1920 and 327 Black 5 4-6-0’s for the LMS in 1935/36.
AW also modified locomotives. In 1926 Palestine Railways sent six of its H class Baldwin 4-6-0 locomotives to AW for conversion into 4-6-2 tank locomotives to work the PR's steeply graded branch between Jaffa and Jerusalem. PR also sent another six H Class Baldwins for their defective steel fireboxes to be replaced with copper ones.
AW's well equipped works included its own design department and enabled it to build large locomotives, including an order for 30 engines of three types for the modernisation of the South Australian Railways in 1926. These included ten "500" class 4-8-2 locomotives, which were the largest non-articulated locomotives built in Great Britain, and were based on Alco drawings modified by AW and SAR engineers. They were a sensation in Australia. AW went on to build 20 large three-cylinder "Pacific" type locomotives for the Central Argentine Railway (F.C.C.A) in 1930, with Caprotti valve gear and modern boilers. They were the most powerful locomotives on the F.C.C.A.
AW also obtained the UK license for Sulzer diesels from 1919, and by the 1930s was building diesel locomotives and railcars. An early example is the Tanfield Railway's 0-4-0 diesel-electric shed pilot, No.2, which was built by AW as works number D22 in 1933. A total of 1,464 locomotives were built at Scotswood Works before it was converted back to armaments manufacture in 1937.
The company can also be credited with helping to create the town of Deer Lake in the Dominion of Newfoundland. Between 1922 and 1925, a hydroelectric station was built at Deer Lake by the Newfoundland Products Company and Sir W. G. Armstrong Whitworth and Company. The canal system used by the hydroelectric station helped to expand the forestry operations in the area. Some of the equipment used in the construction of the Panama Canal was shipped to Newfoundland island. Electricity from the project was used to power the pulp and paper mill in Corner Brook. Since the 1920s, Deer Lake has grown into a major area for the lumber industry, as well becoming a service-oriented centre.
The company also built a hydroelectric station at Nymboida, New South Wales, near Grafton in 1923–1924. This is still in use and is substantially original. In 1925 the company tendered unsuccessfully to construct the South Brisbane-Richmond Gap (on the New-South Wales-Queensland border) section of the last stage of the standard gauge railway linking Sydney and Brisbane. This was a heavily engineered railway which includes a long tunnel under the Richmond Range forming the state border and a spiral just south of the border. Armstrong Whitworth's tender price was £1,333,940 compared with Queensland Railway's tender price of £1,130,142. In the mid-1920s the company clearly was trying to break into the booming Australian market, but was stymied by a preference for local companies.

Shipbuilding was a major division of the company. Between 1885 and 1918 Armstrong built warships for the Royal Navy, Imperial Russian Navy, Imperial Japanese Navy, and the United States Navy. Amongst these were HMS Glatton which, due to bodged construction, suffered a magazine explosion in Dover Harbour less than one month after commissioning.
Armstrong's also built civilian ships, among them the ice-breaking train ferries SS Baikal in 1897 and SS Angara in 1900 to connect the Trans-Siberian Railway across Lake Baikal. Notably, the company built the first polar icebreaker in the world: Yermak was a Russian and later Soviet icebreaker, having a strengthened hull shaped to ride over and crush pack ice.
Mergers and demergers
In 1927, the defence and engineering businesses merged with those of Vickers Limited to create a subsidiary company known as Vickers-Armstrongs. The aircraft and Armstrong Siddeley motors business were bought out by J. D. Siddeley and became a separate entity. Production at the Scotswood Works ended in 1979 and the buildings were demolished in 1982.
