HC Deb 28 January 1980 vol 977 cc546-7W
Mr. Churchill

asked the Secretary of State for Defence what was the percentage of gross domestic product devoted to defence expenditure in the years 194950, 1959–60, 1969–70 and 1979–80, respectively.

Mr. Pym

Using the NATO definition of defence expenditure, the figures are as follows

1950 1960 1970 1980
Major Surface Combatant 322 171 91 75
Submarines 66 53 35 32
Total 388 224 126 107

"Major surface combatant" is defined as a warship of frigate size or above. A simple numerical comparison over the years in question does not, of course, reflect improved capabilities.
