The Miles M.25 Martinet was a target tug aircraft of the Royal Air Force and Fleet Air Arm that was in service during World War II. It was the first British aircraft to be designed specifically for the role of towing targets. Based upon the Miles Master II, the Martinet featured a strengthened airframe to handle the stresses of towing a target drogue. Other differences from the Master included a longer nose, higher cockpit and greater wing span but otherwise the two aircraft shared many common components. The targets and towing gear were contained in a fairing beneath the fuselage and were retracted by an external, wind-powered winch.

The first prototype of the Martinet was flown on April 24, 1942. In total 1,724 Martinets were produced by Miles Aircraft Ltd for the RAF and FAA to meet Air Ministry Specification 12/41. Production continued until the end of the war.

There were two other variants of the Martinet. The M.50 Queen Martinet was a radio-controlled target drone of which 65 were built and a further 17 produced through conversion of an M.25. The M.37 Martinet Trainer was developed during the war but only two were ever produced.
