In 1933 the company was renamed Hawker Aircraft Limited, and it took advantage of the Great Depression and a strong financial position to purchase the Gloster Aircraft Company in 1934. The next year it merged with the engine and automotive company Armstrong Siddeley and its subsidiary, Armstrong Whitworth Aircraft, to form Hawker Siddeley Aircraft. This group also encompassed A. V. Roe and Company (Avro). Hawker Aircraft continued to produce designs under its own name as part of Hawker Siddeley Aircraft, from 1955 a division of Hawker Siddeley Group. The "Hawker" brand name was dropped, along with those of the sister companies, in 1963; the Hawker P.1127 was the last aircraft to carry the brand. The Hawker legacy was maintained by the American company Raytheon who produced business jets (including some derived from the 125, whose original design dated back to de Havilland days) under the "Hawker" name. This was the result of purchasing British Aerospace's product line in 1993. The name was also used by Hawker Beechcraft after Raytheon's business jet interests (Hawker and Beechcraft) were acquired by investors and merged.
