In 1929, D. J. Deschamps, formerly associated with a Belgian manufacturer, constructed a 2-cylinder Diesel test engine. Later, in early 1934, it was announced that Deschamps had designed a Diesel aircraft engine, designated V 3050 for its V-type and displacement. Built by the Lambert Engine and Machine Company in Moline, Illinois, as an experimental airship or trans-oceanic flying boat engine, it was one of the largest Diesel types for aircraft proposed up to that time.

Utilizing a liquid-cooled, two-stroke cycle, the inverted V-12 Diesel Deschamps engine also incorporated direct fuel injection and dual General Electric superchargers. Due to the narrow angle between its cylinder banks, it had a low frontal area. In order to accommodate airship requirements, the engine was fully reversible when operating. While a technically promising engine, financial difficulties prevented continued development and flight testing.
