HC Deb 16 December 1981 vol 15 c129W
Sir Frederick Burden

asked the Secretary of State for Defence why, in view of the major operational role of Royal Navy hunter-killer nuclear submarines in seeking and destroying enemy submarines, they were not used in monitoring the movements of diesel-electric submarines during the North Atlantic Treaty Organisation exercise "Ocean Safari".

Mr. Blaker

In exercise "Ocean Safari" priority was given to exercising Royal Navy hunter-killer nuclear submarines in roles other than monitoring diesel-electric submarines. For security reasons it would be inappropriate to go into details.
