Dassault MD 315 Flamant

The Dassault MD 315 Flamant is a French light twin engined transport airplane built shortly after World War II.

Design work on a twin engined light transport started in 1946 with the MD 303, a development of an earlier project for an eight-seat communications aircraft, the Marcel Bloch MB-30.

The prototype MD 303 first flew on 26 February 1947 powered by two Béarn 6D engines, designed to meet a French Air Force requirement for a colonial communications aircraft.

A re engined version was ordered into production at the new Dassault factory at Bordeaux-Mérignac.

The production aircraft was a low-wing monoplane with twin tail surfaces and a tricycle undercarriage, powered by two Renault 12S piston engines.

Three main versions of the aircraft now named Flamant were produced.

The MD 315 ten-seat colonial communication aircraft, the MD 312 six-seat transport aircraft, and the MD 311 navigation trainer.

The MD 311 had a distinctive glazed nose for its role as both a bombing and navigation trainer.
