§ 50. Mr. Croninasked the Secretary of State for Defence what recent developments have occurred in effective ways of silencing submarines moving below the surface; and what consequent action he proposes to take with regard to the effectiveness of anti-submarine ships and submarines of the Royal Navy.
§ Mr. John MorrisNoise reduction in submarines is under constant review in the Royal Navy and developments and advances continue to improve the effectiveness of submarines in this respect.
To increase the Fleet's ability to detect submarines, a new research programme has recently been commenced which will provide a new generation of improved sonar equipments for surface ships, submarines and A.S.W. aircraft.
