The Armstrong screw breech had already proved successful in the RBL 12 pounder 8 cwt field gun, and the British Government requested it be implemented for heavier guns despite Armstrong's protests that the mechanism was unsuited to heavy guns. [4] Guns were produced at both the Royal Gun Factory in Woolwich, and the Elswick Ordnance Company.
Armstrong gun deployed by Japan during the Boshin War (1868–69).. An Armstrong gun was a uniquely designed type of rifled breech-loading field and heavy gun designed by Sir William Armstrong and manufactured in England beginning in 1855 by the Elswick Ordnance Company and the Royal Arsenal at Woolwich.
The Type 559 was an unorthodox canard design with a massive chin air intake, split vertically, for two reheated de Havilland Gyron engines of 20,000 pounds-force (89 kN) thrust each, placed as in the English Electric Lightning, one above the other.
An accumulator is placed close to the pump with a non-return valve preventing flow back to the pump. In the case of piston-type pumps this accumulator is placed in the ideal location to absorb pulsations of energy from the multi-piston pump. [citation needed] It also helps protect the system from fluid hammer. This protects system components ...
The abandonment of the Armstrong breech-loading design led Britain to begin a major program of building rifled muzzle-loaders to equip its fleet. The Armstrong 110-pound gun was succeeded by various RML 7 and 8-inch guns. 7-inch Armstrong breech-loaders under construction at the time of cancellation were completed as RML 64-pounder muzzle-loaders.
In the US Navy they were referred to as 4.7"/50 Mark 3 Armstrong, or as a "large case" gun, to help distinguish them from the additional earlier "small case" 4.7"/47 Mark 1 and 4.7"/42 Mark 2 guns that had been purchased from Vickers & Sons in the 1890s. Sometime after 1906 two other 4.7" guns were purchased and designated as Mark 4's but no ...
The Armstrong Whitworth 12-inch naval gun of 40 calibres length was designed by and manufactured mainly by Armstrong's ordnance branch, Elswick Ordnance Company. It was intended for the Royal Navy's Royal Sovereign-class battleships, but budgetary constraints delayed their introduction. The first units were instead supplied to Japan.
