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.

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.
