HC Deb 17 May 1982 vol 24 c47W
Mr. Wigley

asked the Secretary of State for Defence what is the estimated expenditure on nuclear weapons by the United Kingdom for each year over the past decade in constant money terms.

Mr. Blaker

The expenditure attributed to our strategic nuclear forces over the past decade, at constant 1982–83 Estimates prices, is as follows:

£ million
1972–73 1973–74 1974–75 1975–76 1976–77
178 164 173 170 186

£ million
1977–78 1978–79 1979–80 1980–81 1981–82
197 173 196 206 300

The increase in 1981–82 is mainly due to the Chevaline programme expenditure, which is now substantially complete.
