Paxman and the Royal Navy
Surface Ships

Paxman has had a long association with the Royal Navy going back to before the Second World War. The importance of the relationship to each party becomes strikingly clear when one looks at the large number of surface ships, listed below, for which Paxman has supplied diesel engines. The Company also built many engines for Royal Navy Submarines, as described elsewhere on this website. The following surface ship listings are not claimed to be complete and comprehensive. Additional information, suggested amendments and corrections would be welcome - see Contact page.

The Ministry of Defence is well-known for demanding the highest levels of technical specification and performance in its equipment procurement. It is testament to the quality of Paxman's engineering that the Royal Navy has relied so heavily on the Company's engines, in war and peace, for over seventy years.

Guidance on understanding the Paxman engine type codes used below can be found on the page Identifying Paxman Diesel Engine Types.

PRE-WORLD WAR 2

Minesweepers - Halcyon Class

Engines (per vessel): One 3MZS auxiliary, rated 80 bhp at 800 rpm continuous, driving a generator set.

The vessels were built in 1934: Halcyon and Skipjack by John Brown & Co, Harrier and Hussar by John Thornycroft & Co.

Destroyers - Tribal Class

Engines (per vessel): Type unknown - for driving auxiliary gen-sets.

Most of Class launched c.1937 and commissioned c.1938. 12 of the 16 were sunk during WW2.

Cruisers - Edinburgh Class

Engines (per vessel): Two 6RX, driving auxiliary generating sets. During HMS Belfast's refit in 1959, the two 6RX engines were replaced by two Paxman 12YHAZ auxiliaries (one still in good order as at August 2005).

Ordered by the Admiralty in 1936, these were enlarged and improved versions of the large light Southampton Class cruisers. HMS Edinburgh was sunk in May 1942. HMS Belfast, launched in 1938 and commissioned in 1939, remained in Royal Navy service until 1965. Now berthed on the south bank of the Thames, between London Bridge and Tower Bridge, she is in the care of the Imperial War Museum. For more details of the ship, opening times and events, go to http://hmsbelfast.iwm.org.uk.

Battleships - King George V Class

Engines (per vessel): Two 6RX, driving 300kW auxiliary generating sets at 900 rpm. Those for King George V were ordered in November 1937 and delivered December 1938. Those for Prince of Wales were ordered in March 1938 and delivered March 1939. The order numbers for these four engines were 50008 to 50011. The two for Renown were 19083, 19084.

HMS Prince of Wales lost in action in December 1941.

Admiralty 52½' Harbour Service Launches

Engines : 6MRW, 100 bhp at 1,000 rpm, for main propulsion.
Engine orders placed in June and December 1939. 10 engines to Sittingbourne Shipbuilding Co Ltd, Sittingbourne, Kent, 2 to Herbert Woods of Potter Heigham, Norfolk.

WORLD WAR 2

The largest proportion of engines built by Paxman for the Admiralty during the War were just over 3,500 12TPM main propulsion engines for Tank Landing Craft. The others, apart from submarine engines, were mainly auxiliaries for electrical power generation. The latter included hundreds of 30 kW, 40 kW, 50 kW and 60 kW, generator sets for destroyers, corvettes, frigates, gunboats, minesweepers, LCG(M)s and LCT8s as well as more powerful generators, up to 300 kW output, for battleships and cruisers, depot ships, and aircraft carriers. Taking all these into account, Paxman was by far the largest producer of main and auxiliary diesel engines for the Admiralty during the War. The following listings of WW2 ships fitted with Paxman engines broadly follow the order in which the relevant engine orders appear in the January 1938 to June 1947 Paxman order book.

Destroyers - N Class

There were other ships in the class and perhaps they received 6RW generator sets from engines entered in the order book as spares. The book does not show a date for the early orders but those for later batches are dated March and July 1942, and October 1943. Most of the 6RW engines for these vessels were supplied during 1942 and 1943. The vessels, as recorded in the Paxman order book, were:

Above ships laid down at the end of WW2 but not completed until 1952/53.

The Paxman YHA Engine

Large numbers of British and allied ships, both naval and merchant, were lost or badly damaged by mines during the War. Two consequences of this were the need, after the war, to replace ships which had been lost and to improve our defensive capabilities for dealing with mine warfare. Part of the response to these needs was a decision to build substantial quantities of inshore minesweepers for which low magnetic signature engines were required. The engine chosen was Paxman's new 4 valve head, direct injection YH engine, which was first developed in its aluminium alloy Admiralty specification form (the YHA) for this purpose and appeared in 1952. Geoffrey Bone, a former Managing Director of Paxman, recalled frequent trips to Foxhill, near Bath, for discussions with the Navy on the development of the engine and the Navy's special requirements. The need for new minesweepers was given added urgency by the Korean War (1950-53) during which enemy mines again caused major problems. In Geoffrey Bone's view, the biggest headache faced by Paxman's senior management in the early 1950s was the pressure to produce YHA engines in the quantities the Navy wanted. Something of the scale of the task can be seen by the number of Ham Class minesweepers listed below, each of which had three 12YHAs. However, these were not the only vessels for which YHAs were required at the time. The YHA met the Navy's requirements so well that it became classified as an ASR (Admiralty Standard Range) 2 engine.

Inshore Minesweepers (IMS) Type 1 - Ham Class

Engines (per vessel): Two 12YHAXM (intercooled) for main propulsion, rated 550 bhp at 1,000 rpm. One 12YHAZ for pulse generation.

Base Minesweepers (BMS) Type 2A

Engines (per vessel): Two 12YHAM for main propulsion, rated 350 bhp at 1,000 rpm.
