HC Deb 16 February 1990 vol 167 c454W
Mr. Cohen

To ask the Secretary of State for Defence what would be the expected savings on the cancellation at this stage of the fourth Trident submarine.

Mr. Alan Clark

It is difficult to quantify accurately the savings that would result because a contract has yet to be placed. It is estimated that savings in the order of £500 million would result if it were decided at this stage not to proceed with the planned order for the fourth Vanguard class submarine.
