context_page_description: The Armstrong Whitworth Argosy was a British post-war transport/cargo aircraft; it was the final aircraft to be designed and produced by aviation company Armstrong Whitworth Aircraft. Although given different internal design numbers, the AW.650 civil and AW.660 military models were, for most practical purposes, the same design, while both models also shared the "Argosy" name.
  Development of the Argosy originates in the AW.66, a proposed twin-engined military transport that was designed with British Air Ministry's Operational Requirement 323 in mind. While Armstrong Whitworth terminated work on the AW.66, it decided to go forward with a civilian-oriented derivative of the design, designated AW.65, as it was judged to be commercially viable. The AW.65 was redesigned to use four Rolls-Royce Dart turboprop engines, and thus was re-designated as the AW.650. On 8 January 1959, the first Argosy conducted the type's maiden flight. On December 1960, the type received Federal Aviation Administration type certification, enabling the initial civil version, referred to as the Series 100, to enter civil service across most parts of the world.
