Hawker Siddeley HS 748

With the construction of eighteen Avro 748 Series 1s for British Skyways Coach-Air (later Dan-Air ) and Argentinean airlines , Avro lost its identity within the Hawker-Sidley group of companies and the aircraft was renamed the HS 748 .

Series 2 began to be produced in 1961, its feature was the increased take-off weight. A total of 198 copies were released, which was a record for British post-war aircraft

More powerful aircraft of the 2A series were released another 71 copies, series 2B - 25 copies.

The Royal Air Force of Great Britain ordered a special version of the 748th with a raised tail unit to accommodate the rear loading ramp and folding ladder (as on the Hawker Siddeley Andover C1 aircraft).

The Hawker Siddeley group (Hawker-Sidley) became part of British Aerospace in the mid -1970s , while the 2B series then became the main production.

Series 1 and 2 of the Avro 748 were manufactured under license in India by Hindustan Aeronautics under the HAL-748 index. In total, HAL built 89 aircraft, 72 for the Indian Air Force and 17 for the Indian Airlines. Later, by order of the Air Force, another 20 2M aircraft were built with an increased cargo hatch. Available in a wide variety of versions, including a radar detection aircraft (AWACS, Airborne Early Warning) with a characteristic large radar fairing.

AWACS

BAe / HS 748 AEW is a long-range radar detection and target designation aircraft developed by the Indian company HAL on the basis of the Hawker Sidley HS.748 passenger turboprop twin-engine aircraft.

The British firm British Aerospace and the Israeli firm Elbit took part in the development of the aircraft. The development of the AWACS aircraft began in India with the HAL branch of Kanpur Division in 1985 .

The radar antenna is mounted in a rotating fairing above the upper surface of the fuselage , so that the plane of rotation of the antenna is higher than the tip of the keel of the aircraft, which reduces signal re-reflection. The German company DASA provided technical assistance in the design and construction of the aircraft (primarily the radar radome fairing) to the Indians.

The first flight, a prototype with a mounted fairing, but without a radar, was made in November 1990 . The prototype plane crashed on January 11, 1999, during the landing approach at the Indian Air Force base by the Aracons ; four crew members and four technicians died. It was assumed that the spent radar on the aircraft will be installed on the IL-76MD , but after the prototype crash the development program for the AWACS aircraft was canceled. ^[one]

Other versions of the 748 include Coastguarder and Super 748 . Coastguarder was a naval patrol scout.

The last 748s were built under the Super 748s index in 1987 and were powered by Rolls-Royce Dart engines.

The aircraft code for ICAO is A748 .
