asked the Secretary of State for Defence if he will give a list of the United States firms that have contracts with his Department; what they supply; and what are the costs.

For the items involved, I would refer the hon. Member to the list in my written reply to the hon. Member for Bournemouth, West (Sir J. Eden) on 16th February, 1966, to which the F I 11A should now be added. It would not be in the public interest to give details of individual contracts but the total dollar cost of outstanding commitments is between £800 million and £850 million if one ignores offsets.
