HC Deb 18 February 1958 vol 582 c135W
Captain Kerby

asked the Parliamentary Secretary to the Admiralty whether the anti-aircraft frigate "Panther" and the aircraft-direction-frigate "Coventry", ordered under the 1956–57 Estimates, have yet been laid down.

Mr. Allan

No. My noble Friend has decided not to build these frigates for the roles originally intended. He intends to build, instead, two more anti-submarine frigates. The change of class of ship will involve a change of name.
