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>
