§ Mr. Strang
asked the Secretary of State for Defence if he will provide a breakdown, by the following budget categories, of the savings attributable to the King's bay decision on maintaining United Kingdom Trident missiles in the United States of America: the submarines, the missiles, the weapons systems, the shore construction, the warhead miscellaneous and unallocated contingencies.
§ Mr. Butler
The savings attributable to the decision to process missiles at King's bay instead of in the United Kingdom are approximately £700 million at average 1984–85 prices and at an exchange rate of £1–$1.38. The missiles and shore construction each account for some 45 per cent. of the saving, with the remainder being attributed mainly to weapon systems.
