HC Deb 16 March 1972 vol 833 cc146-8W
Mr. Dalyell

asked the Minister of State for Defence when he hopes to complete the feasibility study of a medium-range Sparrow weapon, with advanced British components, developed by Marconi and Electrical and Musical Industries.

Mr. Ian Gilmour

The feasibility study should be completed later this year.

Mr. Dalyell

asked the Minister of State for Defence (1) what preliminary estimate he has of the cost of installing British variations in the American Sparrow weapon;

(2) what is the estimated cost of the feasibility study of British instrumentation in an American Sparrow weapon.

Mr. Ian Gilmour

It would be contrary to the usual practice to disclose this information.

Mr. Dalyell

asked the Minister of State for Defence what representations have been made to him, urging the installation of British instruments in American equipment.

Mr. Ian Gilmour

Representations have been received from time to time on ways of maintaining British technology and employment when procurement of foreign weapons is in question. The proposal to install a British guidance head and fuse in the basic Sparrow missile is consistent with these objectives and appears an economical way of meeting our requirement for an improved medium-range missile. It was evolved jointly by the Ministry of Defence and United Kingdom companies.

Mr. Dalyell

asked the Minister of State for Defence why he makes feasibility studies on well-proved and elderly American missiles.

Mr. Ian Gilmour

We consider the Sparrow missile capable of further development to meet our requirement for an improved medium range air-to-air missile. The study to which the hon. Member refers is to establish the feasibility, including the cost implications, of achieving the necessary modifications with British components.

Mr. Dalyell

asked the Minister of State for Defence what discussions he has had with the Raythion Corporation on questions of patent, in relation to the Sparrow weapon.

Mr. Ian Gilmour

Some preliminary discussions have already taken place but this is one of the points to be covered in the feasibility study.

Mr. Dalyell

asked the Minister of State for Defence what representations he has had from the United States Government as to their participation in the Hawker Siddeley Short-Range Air-to-Air Missile 75; and what reply he has sent.

Mr. Ian Gilmour

None.
