HC Deb 07 May 1981 vol 4 c114W
Mr. Trippier

asked the Secretary of State for Defence what the 30 per cent. of the cost of the Trident system which will be spent outside the United Kingdom consists of.

Mr. Speed

This will be spent in the United States, mainly on the Trident missiles themselves—excluding the warheads—and on associated shipborne and shore-based equipments and supporting services.
