Anti-Submarine Frigates 9. Mr. Watkinson asked the Parliamentary Secretary to the Admiralty when the trials of the first anti-submarine frigate will be completed. Mr. Callaghan The first of the antisubmarine frigates to be converted from destroyers is expected to be in service by the autumn. Mr. Watkinson The Parliamentary Secretary says "in service." Does that mean that by that time he will have completed the trial, and that all the gear on board will have been tested? Mr. Callaghan Yes, Sir. Commander Maitland Will the hon. Gentleman make it possible for Members of the House to see this ship? Mr. Callaghan I am not sure about this ship. That might be possible later, but I have hopes of arranging a programme of visits for hon. Members during the summer.
