The Argus 411 was an air-cooled, inverted-V12 aircraft engine developed by Argus Motoren in Germany during World War II.{{cite book |last=Gunston |first=Bill |title=World Encyclopaedia of Aero Engines |year=1989 |publisher=Patrick Stephens Limited |location=Cambridge, England |isbn=978-1-85260-163-8 |edition=2nd |page=16}}
Design and development
The As 411 was a refined and more powerful version of the Argus As 410. Most 411 production was undertaken by Renault in occupied Paris, these engines were used to power the Siebel Si 204 and the postwar Dassault MD 315 Flamant. It developed 600 PS (592 hp, 441 kW) at 3,300 rpm
Following the end of World War II, Renault continued to manufacture the engine as the Renault 12S. After the merger of the French aircraft engine manufacturers into SNECMA in 1945, production continued under the new designation SNECMA 12S.
