Type 22 frigate
Following the cancellation of the aircraft carrier programme CVA-01 in 1966, the Royal Navy undertook a reappraisal of the surface fleet, and concluded that the following five new ship types were required: Of these, the air defence destroyer appeared to had been given highest priority, the imperative being to get Sea Dart to sea in numbers to replace the air defence capability which would be lost with the retirement of the carrier fleet.The principal ASW weapons systems were the ship's Westland Lynx helicopter and triple torpedo tubes (STWS), with the large Type 2016 sonar a key part of the sensor fit.A pair of 40 mm L/60 Bofors were fitted in the first batch for patrolling and "junk-busting" on summer Indian Ocean deployments, but proved an impediment in the Falklands War where Type 22 captains considered they interfered with concentrating on the Seawolf setup.Visually, and in addition to the increase in length, the biggest difference was the sharply raked stem, usually indicative of bow sonar though none of the Batch II ships was thus fitted.The larger hull also improved sea keeping, but never achieved the expected quietness with towed arrays due to failure to raft mount the diesel generators.Further improvements from HMS Brave onwards included a taller helicopter hangar, giving the ships the ability to carry a single Westland Sea King or EH101 Merlin instead of two Lynx.The four Batch III ships – Cornwall, Cumberland, Campbeltown and Chatham – were completed to a revised design which reflected lessons learned in the Falklands War.On 11 January 1985, Mr. Dalyell asked the Secretary of State for Defence: "what is the latest cost estimate of a type 22 frigate, with stores, spare parts and ammunition.""[28] In February 1998, in response to a written question in parliament by Mike Hancock, the Minister of State for the Armed Forces, Dr John Reid said: "Type 22 frigates achieved approximately 82 to 86 per cent.The Minister of State for the Armed Forces, John Spellar, replied in a written answer: "The planned service for each ship was 18 years" and The additional information is given in the table.
