The 'Avro 707' was a British experimental aircraft built to test the
delta wing design for the Avro 698 jet bomber (later to become the
Vulcan), and was effectively a one-third scaled-down version of that aircraft.
Design and development
The prototypes were ordered by the Ministry to
specification E.15/48. The aircraft were produced cheaply and quickly using components from other aircraft. Five prototypes were built in the end. Only the first three produced provided useful information for the Vulcan project, the last two flying too late to be of much relevance.
The first prototype, the Avro 707, crashed on
31 September 1949.
[1] Consequently the second prototype was converted during building with the pointed nose planned for the 707A to become the '707B'. The B was given the same dorsal engine intakes as the 707. The B would eventually end up as spares for the others. The next one to fly was the '707A', a faithful copy of the Type 698's wingform including engine intakes, and intended for high speed testing. In 1956 it was transferred to Australia where it served until 1967 when sold off to a local resident. The next aircraft were ordered to E.10/49 in November 1951. These were to be a second 707A and two of a side by side cockpit version - the '707C'. The 707Cs would be used to give pilots experience but the second 707C was cancelled. These two flew in 1953 by which point the Vulcan prototype was already flying.
The Avro 707 made its final public appearance at the
Farnborough Air Show; the four surviving examples of the aircraft flying alongside two Vulcan prototypes.
Two examples of the Avro 707C two-seat variant survive. One is located at the
RAF Museum, Cosford near
Wolverhampton, the other at the
Museum of Science and Industry in Manchester. A single example of the 707A variant survives, at the
RAAF Museum in
Point Cook, Victoria.
