HC Deb 04 December 1989 vol 163 c100W
83. Mr. Foulkes

To ask the Secretary of State for Transport what action his Department is taking to test systems which alert submarines to the presence of fishing vessels above them; and if he will make a statement.

Mr. McLoughlin

Two proposals for acoustic devices have been received which have been sent to the Admiralty research establishment to assess their suitability as a warning to submarines of the presence of fishing vessels and their nets.
