Editing Rolls-Royce Merlin (section)

==Applications==
In chronological order, the first operational aircraft powered by the Merlin to enter service were the Fairey Battle, Hawker Hurricane, and Supermarine Spitfire.<ref>Lumsden 2003, p. 205.</ref> Although the engine is most closely associated with the Spitfire, the four-engined Avro Lancaster was the most numerous application, followed by the twin-engined de Havilland Mosquito.<ref>Lumsden 2003, pp. 208–209.</ref>

===Postwar===
At the end of World War II, new versions of the Merlin (the 600- and 700-series) were designed and produced for use in commercial airliners such as the [[Avro Tudor]], [[military transport aircraft]] such as the [[Avro York]], and the [[Canadair North Star]] which performed in both roles. These engines were basically military specification with some minor changes to suit the different operating environment.<ref>Lumsden 2003, pp. 214–215.</ref>

A Spanish-built version of the [[Messerschmitt Bf 109]] G-2, the 1954 [[Hispano Aviación HA-1112|Hispano Aviación HA-1112-M1L ''Buchon'']], was built in [[Hispano Aviación|Hispano's]] factory in [[Seville]] with the Rolls-Royce Merlin 500/45 engine of {{convert|1600|hp}}&nbsp;– a fitting powerplant for the last-produced version of the famous Messerschmitt fighter, as the Bf 109 V1 prototype aircraft had been powered by the Rolls-Royce Kestrel V-12 engine in 1935.<ref>Lumsden 2003, p. 214.</ref>

The [[CASA 2.111]] was another Spanish-built version of a German aircraft, the [[Heinkel He 111]], that was adapted to use the Merlin after the supply of [[Junkers Jumo 211]]F-2 engines ran out at the end of the war.<ref>Wilson, Randy. [http://rwebs.net/dispatch/output.asp?ArticleID=17 It's a Heinkel: the Luftwaffe's workhorse Heinkel 111 bomber] {{webarchive|url=https://web.archive.org/web/20060928035717/http://rwebs.net/dispatch/output.asp?ArticleID=17 |date=28 September 2006 }} rwebs.net, ''The Dispatch''. Volume 12, Number 4, Winter 1996. Retrieved: 6 September 2009</ref> A similar situation existed with the [[Fiat G.55#GY|Fiat G.59]] when available stocks of the Italian licence-built version of the [[Daimler-Benz DB 605]] engine ran short.<ref>Green and Swanborough 1994, p. 211.</ref>

The Australian built [[Avro Lincoln]] from A73-51 used Australian built [[Commonwealth Aircraft Corporation]] Merlin 102s.
A total of 108 CAC Merlins were built by the time production ended.

===Alternative applications===
{{further|Rolls-Royce Merlin alternative uses}}

A non-supercharged version of the Merlin using a larger proportion of steel and iron components was produced for use in [[tank]]s. This engine, the [[Rolls-Royce Meteor]], in turn led to the smaller [[Rolls-Royce Meteorite]].<ref>Pugh 2000, p. 254.</ref> In 1943, further Meteor development was handed over to [[Rover Company|Rover]], in exchange for Rover's [[Rover Company#Second World War and gas turbines|gas turbine]] interests.<ref>Harvey-bailey 1995, p. 83.</ref>

In 1938, Rolls-Royce started work on modifying some Merlins which were later to be used in British [[Motor Torpedo Boat|MTBs]], [[Motor Gun Boat|MGBs]], and RAF Air-Sea Rescue Launches. For these the superchargers were modified single-stage units and the engine was re-engineered for use in a marine environment. Some 70 engines were converted before priority was given to producing aero engines.<ref>Harvey-Bailey 1995, pp. 83–84.</ref>

Experiments were carried out by the [[Irish Army]] involving replacing the Bedford engine of a [[Churchill tank]] with a Rolls-Royce Merlin engine salvaged from an [[Irish Air Corps]] [[Supermarine Seafire|Seafire]] aircraft. The experiment was not a success, although the reasons are not recorded.<ref>Martin 2002, p. 58.</ref>
