development in 1956: the English Electric P.1, the prototype of which
had flown two years earlier and which was due to enter service with the
RAF in 1959, and which eventually did so in 1961; and the Saunders-
Roe P.177, which had not yet flown, but which had a novel design
incorporating a rocket as well as a jet engine and which was intended to
fulfil RAF and Admiralty requirements for a high-altitude interceptor in
1960. The development of the P.177 was subject to strict cash limits
because the Treasury would not approve an increase until ministers had
completed reviewing the aircraft programme. The RAF dropped the
P.177 as a result of the 1957 Defence White Paper but the First Sea
Lord, Mountbatten, argued that if the P.177 was cut from the navy’s
programme the fleet would be in the ‘ridiculous position’ of being
unable to defend itself against the up-to-date aircraft that the Soviet
Union could be expected to supply to countries with which Britain
might be engaged in a limited war. Nevertheless, Sand ys decided in
October 1957 that a new naval fighter could not be afforded and, once it
became apparent that West German interest in the P.177 would not
lead to an order, the project was cancelled.

There were also two projects for night and all-weather fighters: a new
variant of the Javelin which, being subsonic, was considered to be of
limited value and likely to be subject to delay, and was consequently
dropped; and a design for Operational Requirement (OR) 329, which
was still on the drawing board. A gap was anticipated between the
existing Javelin becoming obsolescent and OR 329 becoming opera-
tional, and consideration was given to ordering a Canadian supersonic
aircraft, the CF-105. Nigel Birch, the secretary of state for air, thought
in March 1956 that such a step would ‘have a most salut ary effect on the
British aircraft industry’, besides reducing the research and development
budget.

It was assumed that the CF-105 would have to be ‘anglic ised’
by being given British rather than American engines and avionics, and
the Ministry of Supply considered that the British aircraft industry could
not cope with both the CF-105 and OR 329. In the event neither project
survived the defence policy review. Surface-to-air (SAM) guided mis-
siles were under development and the RAF’s Bloodhound was due to
