The SNECMA 14R was a 14-cylinder two-row air-cooled radial engine developed in France just prior to the start of World War II from the Gnome-Rhône 14N. The 14N radial engine was itself an improved version of the popular pre-war Gnome-Rhône 14K Mistral Major series; designed and manufactured by Gnome et Rhône, a major French aircraft engine manufacturer whose origins pre-date the First World War.

| - The SNECMA 14R was a 14-cylinder two-row air-cooled radial engine developed in France just prior to the start of World War II from the Gnome-Rhône 14N. The 14N radial engine was itself an improved version of the popular pre-war Gnome-Rhône 14K Mistral Major series; designed and manufactured by Gnome et Rhône, a major French aircraft engine manufacturer whose origins pre-date the First World War. The improved 14R was initially known as the Gnome-Rhône 14P and then the Gnome-Rhône 14R. There were several improvements such as the introduction of a longer crankshaft and crankcase with a centre bearing, an increase in cylinder capacity, and a two-speed compressor. These changes allowed the engine to deliver 1,400hp at take-off and 1,300hp at 1,500m (1st gear) and 1200hp at 4000m (2nd gear). This came at the cost of a much increased total weight. It was expected that further development, such as the introduction of higher grade fuels, would lead to a power output of 1,660hp at low altitude. With the Fall of France, engine development was stopped under the occupation. After the war, development recommenced; however production of this engine after 1945 was transferred to the newly formed SNECMA and the engine was renamed the SNECMA 14R. (en)
