Avro outlined the 748 in an offer to re-enter the common market in the 1950s in reckoning of a decrease in its military airplane business (after Britain's well known 1957 Defense White paper).

Surfacing as the Avro 748 in 1958, the task got to be a piece of the Hawker Siddeley bunch when it framed in 1959 with the merger of a few British flight organizations, including Armstrong Whitworth, Avro, Blackburn, De Havilland, Folland, Gloster, and Hawker. From July 1 1963 the different characters vanished.

The new air ship made a fruitful lady flight on June 24 1960, and four model airplane (two for static testing) were fabricated. The principal generation Series 1 flew on August 30 1961.

Arrangement 1 creation airplane were controlled by two 1400kw (1880ehp) Dart Rda.6 Mk 514 turboprops, and the initially entered administration in December 1961 with Skyways Airways. Just 20 (+4 in India) Series 1 were fabricated nonetheless, as at that point the enhanced Series 2 was at that point flying.

The Series 2, in its 2, 2a and 2b variations, was the best of the line, the first flying on November 6 1961. The Series 2 varied from the 1 in having higher weights and all the more influential motors. The Series 2b showed up in 1977, offering a scope of flight optimized and different upgrades, including an expanded wing compass. Numerous Series 2a and 2b were furnished with a vast forward fuselage cargo entryway.

The most progressive 748 variation, the Super 748, was an enhanced variant of the 2b and made its first flight in July 1984. Joining the enhancements of the 2b, it likewise offered a modernized flightdeck, enhanced proficiency and hushkitted Dart motors, and new cookroom and interior fittings.

Seller Siddeley, where the 748 was known as the HS-748, was blended into British Aerospace and from January 1 1978 the Hawker Siddeley name vanished. Generation of the airplane sort, now the Bae-748, finished in 1988 with the last flying that December (with conveyance the accompanying month).

The Indian Ministry of Defense had communicated an early enthusiasm toward the 748 which brought about an agreemnet to gather and manufacture the airplane under permit. The initial four flying machine, Series 1, were constructed by Kanpur (Indian Air Force Manufacturing Depot), with the first flight made on November 1 1961. Because of a poor creation rate, the generation was assumed control from the fifth airplane by Hindustan as the HAL-748, who initially created the Series 2 and later the Series 2m with the front fuselage cargo entryway. The last one was conveyed in September 1984, to the Indian Air Force.

An unique military variation with a back stacking slope and a "stooping" undercarriage was the HS-780 (HS-748mf) which was referred to in British military administration as the Andover C1. The standard HS-748 was named the Andover Cc2. Later a few C1s were changed over for photograph obligations as the C1(pr) and radar alignment obligations as the E3 and E3a. A couple of ex British and New Zealand military C1s entered business administration.

The HS-748 turned out to be a truly effective turboprop carrier and stays well known both as an air transport and tanker in common and military utilization.
