Rademaker (F49), a type 22 frigate of the Brazilian Navy

The Type 22 Broadsword class is a class of frigate built for the Royal Navy. Fourteen of the class were built in total, with production divided into three batches. Four Batch 3 ships remain in service with the Royal Navy. Seven ships of the earlier batches have been sold for further service with Brazil, Romania and Chile, two have been sunk as targets and the other sold for scrapping.

Design

The Type 22 was designed to be a specialist anti-submarine warfare vessel as part of the Royal Navy's contribution to NATO. Since then they have evolved into a general purpose frigate with weapons for use against other surface ships, aircraft and submarines. They were built in three batches giving rise to three sub-classes, the first Broadsword of four ships, the second Boxer of six ships and the third and final, Cornwall of four ships.

The four Broadswords (which included two Falklands War veterans) were sold to Brazil in the mid 1990s. Romania has acquired and modernized two of the Batch 2 ships, while a third was purchased by Chile.

The ships have enhanced command, control and co-ordination facilities that results in their often being used as deployment flagships.[1]

Evolution

The Type 22 was intended as a follow-on class to frigates of the successful Type 12 ("Rothesay" and "Whitby") and the Type 12M ("Leander") classes at a time when the Royal Navy drew a clear distinction between anti-submarine escorts (known as frigates) and air defence ships (destroyers). Type 22s thus began as ASW vessels, but were later to evolve into GPFs (general-purpose frigates) as the ASW/AD distinction blurred.

The role of the Type 22 within overall force architecture can be gauged from a naval staff requirement drawn up in 1967. Following the demise of the future carrier programme (CVA-01), the RN undertook a complete reappraisal of the future surface fleet, and concluded that the following five new ship types were required:

- A cruiser-type ship to operate large ASW helicopters (this requirement eventually led to the Invincible class carriers);

- An air defence destroyer smaller and cheaper than the 'County' class (this resulted in the Type 42 programme);

- A missile-armed frigate as an eventual successor to the Leander class (this requirement led to the Type 22);

- A cheap patrol frigate (this requirement led to the Type 21); and

- A dual-role MCMV successor to the 'Ton' class (this resulted in the 'Hunt' class)

Of these, the air defence destroyer appears to have 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 premature demise of the carrier fleet.

Visually, the Type 12 lineage in the Type 22 design is less than obvious, though there are said to be similarities in the underwater hull form. Due to the workload of the Admiralty design department in the 1960s, a private design (Type 21) was purchased as an interim stop-gap whilst the Type 22 was under development. The design process, already hampered by the priority given to the Type 21 and the urgently-needed Type 42, was further protracted by attempts to produce a common Anglo-Dutch design. The first Type 22 order was placed in 1972 with Yarrow Shipbuilders; Yarrow undertook much of the detailed design work whilst overall responsibility remained with the Ship Department at Bath.

The length of the first four Type 22s was dictated by the dimensions of the undercover Frigate Refit Complex at Devonport Dockyard. The ships would be powered by a combination of Olympus and Tyne gas turbines in a COGOG (COmbined Gas turbine Or Gas turbine) arrangement. Machinery spaces were sited as far aft as possible to minimise shaft lengths. The after configuration was dictated by the requirement for a large hangar and a full-width flight deck..

Weapons fit was determined by the primary ASW role combined with a perceived need for a general purpose capability. The principal ASW weapons systems were the ship's Lynx helicopter and triple torpedo tubes (STWS), with 2087 towed array sonar a key part of the sensors fit. Air defence was provided in the form of two 'six-pack' launchers for the Seawolf (GWS 25) point-defence missile system. Surface warfare requirements were met by the provision of four Exocet SSM launchers, the standard RN fit at that time. The Broadsword design was unique to the Royal Navy in lacking a main gun armament. Although some of the Leander Class frigates had lost their main gun during upgrades, (Broadsword was the first to be designed from the beginning without a main cannon. This changed with the introduction of the Batch III ships.

Ordering of Type 22s proceeded slowly, in part because of the comparatively high unit cost of the ships. The unit cost of the last Type 12Ms had been about £10m; Type 21s cost around £20m each; when the first Type 22s were ordered, unit costs were estimated at £30m though, by the time that the first ship (HMS Broadsword) commissioned in 1979, inflation had driven this figure up to £68m, which was far higher than the cost of the contemporary Type 42s (HMS Glasgow, also commissioned in 1979, cost £40m).

After the first four ("Batch I") ships, the design was "stretched", with the Frigate Refit Complex suitably enlarged. 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). An important addition to the Batch II group was a new Computer Assisted Command System (CACS-1), replacing the CAAIS fitted to the Batch I ships. A revised machinery installation was adopted from HMS Brave onwards, with Spey turbines replacing the previous Olympus. The future machinery arrangement would be COGAG (Combined Gas turbine And Gas turbine). By 1982, the quoted unit cost of a Type 22 had risen to £127m.

HMS London

This might have been the end of the Type 22 programme had it not been for the Falklands War (1982), in which the two ships of the class present (Broadword and Brilliant) acquitted themselves well. Replacement for ships lost in the South Atlantic were all of this class.

The last four ships of the class (the Batch III ships Cornwall, Cumberland, Campbeltown and Chatham) were of a greatly improved design. Reflecting lessons learned in the Falklands, the weapons fit was changed, becoming more optimised to a general warfare role. The ships were fitted with the 4.5" (114m) gun, primarily for NGS (Naval Gunfire Support for land forces). Exocet was replaced by the superior Harpoon with eight GWS 60 missile launchers fitted laterally abaft the bridge, and each ship would carry a Goalkeeper CIWS (Close-In Weapon System).

In their final form, the Type 22s were the largest frigates ever built for the Royal Navy - the follow-on Type 23 class would be appreciably smaller ships. Reflecting this, Type 22s are often deployed as flagships for NATO Task Groups.

Nomenclature

It was originally envisaged that all Type 22s would have names beginning with 'B' (Broadsword, etc), following the 'A' names used for Type 21s (Amazon, etc). This changed when two under-construction ships (Sheffield and Coventry) were re-named to commemorate ships lost in the South Atlantic, with London being similarly honoured. The alphabetical progression was re-established with the Batch III ships (Cornwall, etc) before being temporarily abandoned with the Type 23 class, named after Dukedoms (Norfolk, Lancaster, etc). The Royal Navy's latest escort class (the Type 45 or Daring class) have re-introduced the alphabetical progression.

In May 2000, the Secretary of State for Defence was asked: "what was the planned service life of(a) HMS London, (b) HMS Beaver, (c) HMS Boxer and (d) HMS Brave; and what was the forecast date for withdrawal from Royal Navy service, prior to the decision in the Strategic Defence Review to dispose of them." The Minister of State for the Armed Forces, John Spellar, replied: "The planned service for each ship was 18 years. The additional information is given in the table."[32] Note that the 18 years was dated from the date of acceptance, not the date first commissioned.

In July 2000, the Secretary of State for Defence was asked: when he planned to withdraw the remaining Type 22 Batch II frigates from service. The Minister of State for the Armed Forces, John Spellar, replied: "Plans for the withdrawal from service of the Type 22 Batch 2 frigates currently in service are as follows:"

  • "HMS Sheffield 2012 - to be superseded by a T45 Destroyer"
  • "HMS Coventry 2001 - to be superseded by HMS St. Albans, a T23 Frigate."[33]

This date is important because maintenance cycles, etc. are generally calculated from the acceptance date.
