INSIDE TH The Batch 3 Type 22 frigate


Now News


The generic Type 22 frigate was originally intend- ed to replace the successful Leander-class ship. Yarrows were given the job of working out the details to produce a large and powerful warship against an overall design development by the Ministry of Defence. This provided the Navy with a frigate not only


adept in its main anti-submarine warfare role, but also as a general-purpose frigate - as was shown in the Falklands War, when HMS Brilliant and HMS Broadsword served with distinction, accounting for several Argentine aircraft and in constant demand for other roles around the task group.


Indeed, Jane's Fighting Ships of 1983 won-


HMS Sheffield of the six-strong Batch 2 no longer fly the White Ensign, but the four ships of Batch 3 score highly when sailors rate the relative merits of units of the surface flotilla. HM ships Cornwall (F99), Cumberland (F85), Campbeltown (F86) and Chatham (F87) are big, spacious ships - the largest frigates ever built for the Navy and, with a fully-laden displacement of 4,900 tons, comparable in size to wartime light cruisers.


dered "how the term 'frigate', which is used for Type 22 because of their primary ASW role, will stand up with the new Batch 3 design, possess- ing greater anti-ship capability than the Type 42 destroyers, is not clear." The first four ships (Batch 1) and all except


These four ships are very different to their


them to accommodate Sea King helicopters, although a Lynx is more normally carried. The difference is probably most noticeable in


Batch 1 sisters. For example, they are powered by pairs of Rolls-Royce Spey and Tyne engines instead of Olympuses and Tynes, and the all-missile con- cept was ditched when the Vickers 4.Sin gun was chosen instead of the Exocet missile launchers featured in the first ten ships. They also have a larger flight deck, allowing


the ships' profiles - the Batch 1s were almost 20 metres shorter than the later ships, and the Batch 2 and 3 versions have a more sharply- raked bow. The Batch 3 ships have accommodation for a


Flag Officer and staff, and their size and commu- nications capability make them ideally suited to the role of flagship - HMS Cornwall acted as such in the major global deployment Naval Task Group 2000. Batch 3 ships have a COGAG power arrange-


ment - Combined Gas turbine And Gas turbine - which gives them a top speed in the order of 30 knots, although an economical cruising speed in excess of 14 knots on Tynes alone is a common scenario. Each has a ship's company of 250, with 30 or

The first of the Batch 3s, HMS Cornwall, was launched at Yarrows in October 1985, with her sisters going down the slipway at the rate of one a year thereafter, at Yarrows (Cumberland), Cammell Laird (Campbeltown) and Swan Hunter (Chatham) respectively.
