The SNCAC Martinet was a German-designed but French-built twin-engined military trainer and light transport monoplane. It was operated by the French military and in small numbers by French airlines from the late 1940s.

Development[edit]

To aide the German war effort the SNCAC factory at Bourges was ordered to produce 455 Siebel Si 204s light transports for the Luftwaffe. Production started in 1942 and 168 had been delivered before the Liberation stopped production. The French decided to continue producing the aircraft and designated the aircraft NC.700. Only a prototype NC.700 was built powered by Renault 12S-00 engines (derived from the German AS-411) although the designation was also used for a small number of aircraft originally intended for the Luftwaffe and diverted to the French Air Force.

The company then produced two variants; the NC.701 Martinet based on the Si 204D with a glazed unstepped nose and powered by two Renault 12S engines, and the NC.702 Martinet with a conventional stepped windscreen nose based on the Si 204A.

Operational history[edit]

The Martinet was used by both the French Air Force and Navy and the final example did not retire until 1963. A small number were used by commercial operators including Air France but were soon replaced by larger aircraft like the Douglas DC-3. A number were used by the French Postal Service but they were grounded following an accident to F-BBFA is July 1946. The aircraft was used by the IGN for photo-survey work and a few aircraft were also exported to Poland and Sweden for use on photo-mapping duties.
