HC Deb 23 February 1965 vol 707 c87W
Captain Kerby

asked the Secretary of State for Defence to what extent, in view of Her Majesty's Government's decision to complete only four Polaris missile submarines, only one such submarine will be available for patrol; and if he is satisfied that these submarines will make an adequate contribution to the Western deterrent.

Mr. Healey

Such a force will be able to keep one submarine on station, and often two. It would make a substantial contribution to an Atlantic Nuclear Force.
