The Leander class, comprising twenty-six frigates, was among the most numerous and long-lived classes of frigate in the Royal Navy's modern history. The class was built in three batches between 1959 and 1973. It had an unusually high public profile, due to the popular and acclaimed Warship BBC television drama series.

The Leander design or derivatives of it were built for other navies:

Design

On 7 March 1960, the Civil Lord of the Admiralty C. Ian Orr-Ewing stated that the "Type 12 "Whitby" class anti-submarine frigates are proving particularly successful... and we have decided to exploit their good qualities in an improved and more versatile ship. This improved Type 12 will be known as the Leander class. The hull and steam turbine machinery will be substantially the same as for the Whitbys. The main new features planned are a long-range air warning radar, the Seacat anti-aircraft guided missile, improved anti-submarine detection equipment and a light-weight helicopter armed with homing torpedoes. We shall also introduce air conditioning and better living conditions."[1] The 1963 edition of Jane's Fighting Ships described it a "mainly anti-submarine but flexible and all purpose type".[2]

"The Leander class have the same hull and substantially the same steam turbine machinery as the Whitby class, but are a revised and advanced design and will fulfil a composite anti-submarine, anti-aircraft and air direction role. The 40mm guns will eventually be replaced by Seacat ship-to-air launchers. The ships are equipped with VDS (Variable Depth Sonar), formerly known as dipping asdic."[2]

A Batch 3A Seawolf conversion in 1987

The Seawolf conversion gave the broad-beamed Leaders Exocet anti-shipping missiles, Seawolf anti-air missiles, Sonar 2016, and the ability to operate the Lynx helicopter.[18] Only five of the broad-beamed Leaders were converted to carry Seawolf. "Conversion of the remaining five was not undertaken on grounds of cost (£70 million for each refit) and, as a lesser consideration, to retain some ships for the NGS role."[24] (NGS stands for naval gunfire support.)

Batch 2 TA & Batch 1B - towed array conversions

HMS Argonaut, a batch 2 Exocet conversion fitted with a towed array, in 1995. Note the platform at the stern added in the towed array conversion in 1982-83.

In 1981 the Admiralty said that intended to devote "substantial resources to improving the effectiveness of the sensors and anti-submarine weapons ... This includes the new passive towed array system that we hope to introduce into service next year."[28]

The former destroyer Matapan and the frigate Lowestoft were used for testing prototypes in 1978-81. [29] It was planned to install them on Rothesay conversions, but this was not possible due to industrial strikes.[29] Scheduling then made it easier to fit them on board four of the Batch II Leanders. "Compensation for the additional 70 tons of top weight included lowering the Exocet launchers. This interesting quartet was to have been followed by five Batch III Leanders, but the latter fell foul of the Nott cancellations. A fifth Leander, the Ikara-carrying HMS Arethusa, was fitted with a towed array in 1985, the year the towed-array trials ship Lowestoft was withdrawn from service."[29]

Admiral Sir Julian Oswald said to the Defence Committe in 1989, "in order to capitalise on the really very exciting and important development of towed arrays, we had to get them to sea as soon as we could. The only sensible, cost-effective option open to us was to take some relatively older ships - the Leanders - and convert them quickly to the towed array. We have done that with great success, and the peacetime patrols have achieved some remarkable results, but there has been a price to pay because of the age of those ships."[30]

In general, "as a ship gets older it tends to get noisier - the hull and also the propulsion system".[31] Admiral Sir Julian Oswald spoke "to counter the presumption that older ships get noisier. That is not necessarily true and it is not true, in my experience, in the case of the Leanders because understanding of ship generated noise is improving all the time and our techniques for countering it are improving - our noise monitoring and so on - so, despite the fact that these ships are getting older, they are in many cases managing to improve their performance with regard to ship noise."[32] Captain Geoffrey Biggs said "the Leanders are remarkably quiet in operation and our experience has been that they have made excellent towed-array platforms despite the rather short notice of actually getting the towed-array programme together to start with. They actually perform very well."[32]

Five ships were converted to use Waverley Type 2031Z towed array (passive search very low frequency). They were as follows:[33]

RN service

The ships performed excellently in RN service, with relatively low noise levels giving the 2031(I) towed sonar mounted during the 1970s a range of more than 100 miles, better than that of the more advanced 2031(Z) sonar when fitted in the Type 22 class. However, all Leanders in RN service were decommissioned by the early 1990s due to the ships' aging design and the high number of crew. HMS Scylla was sunk 27 March 2004 as an artificial reef off Cornwall, ten years after her decommissioning in 1994.

Running costs

Date Running cost What is included
1972-73 £250,000[35] Average annual maintenance cost per vessel for Leander class frigates
1980-81 £6 million[36] Average current cost for a normal refit of a Leander class frigate.
1981-82 £6.8 million [37] Average annual running cost of Leander frigates at average 1981–82 prices and including associated aircraft costs but excluding the costs of major refits.
1985-86 £6.5 million[38] The average cost of running and maintaining a Leander class frigate for one year.
1987-88 £3.8 million[39] The average annual operating costs, at financial year 1987-88 prices of a Leander class frigate. These costs include personnel, fuel, spares and so on, and administrative support services, but exclude new construction, capital equipment, and refit-repair costs.

Overseas Service

Leander class frigates were also successfully exported to serve in the Royal New Zealand Navy and Chilean Navy; in the latter they were designated as the Condell class. Further Leander class frigates were built under licence in Australia as the River class for the Royal Australian Navy, India as the Nilgiri class and the Netherlands as the Van Speijk class. Royal Navy ships were sold to the navies of Chile, Ecuador, New Zealand (Bacchante becoming HMNZS Wellington and Dido becoming HMNZS Southland), India and Pakistan.

Some Leanders remain in service with foreign navies, remaining in service with Ecuador, India, Indonesia (former Van Speijk class). Pakistan decommissioned the last of its Leander class frigates, PNS Zulfiqar, in January 2007, [40]

HMNZS Canterbury, the last steam-turbine driven Leander class frigate in the Royal New Zealand Navy, was decommissioned in Auckland on 31 March 2005 after 33 years operational service. In 2006 it was announced that the ship was to be sunk as a dive attraction in the Bay of Islands, and this was carried out on 3 November, 2007 at Deep Water Cove.
