Armstrong Whitworth Apollo Armstrong Whitworth Apollo The Armstrong Whitworth AW.55 Apollo was a 1940s British four-engine turboprop airliner built by Armstrong Whitworth at Baginton. The aircraft was in competition with the Vickers Viscount but was beset with engine problems and only two were built. The requirement resulted from the Brabazon Committee's Type II design, calling for a small, medium-range pressurized aircraft to fly its less-travelled routes which became Air Ministry Specification C.16/46 for an aircraft able to carry 24-30 passengers over 1,000 mi (1,610 km) at a cruising speed of .

Vickers-Armstrongs its acquisitions Vinters plc. Vickers-Armstrongs inherited the Vickers machine gun of 1912 used in World War I from Vickers Limited. There were other Vickers machine guns aside from the regular water-cooled model (known universally as the "Vickers"): the Vickers-Berthier (VB) machine gun used by the Indian Army, the Vickers "K" .303 aircraft machine gun developed from it, and the Vickers "S" 40 mm aircraft gun. An unusual machine gun also made was the Vickers Higson. Vickers produced larger weapons such as the Ordnance QF 2-pounder gun used on tanks. In 1948 Vickers bought the Australian business of Charles Ruwolt Ltd
