The SNECMA ATAR 101 is a French axial-flow turbojet engine built by SNECMA. It was derived from engines and design work carried out at BMW in Germany during World War II, and extensively developed though a progression of more powerful models. The name is derived from its original design group, Atelier Technique Aéronautique de Rickenbach employing Hermann Östrich and many of the wartime BMW gas turbine design group as well as other German engine design teams. The ATAR 101 powered many of the French post-war jet aircraft, including the Étendard IV, Super Mystère B2, etc..
The 101E fitted with an afterburner to produce the 101G.
