Design and development

Argus Motoren already supplied a limited number 150 hp and 200 hp aircraft engines to the Imperial German Navy in the Summer of 1914.[2] As these engines did not prove successful Argus decided to concentrate its development efforts on an improved 180 hp (130 kW) six-cylinder type which became accepted into service in January 1916 as the Argus As III.[3] License production of the engine was ordered at Deutz, Güldner, M.A.N., Opel and Stoewer.[3] First operational experience with the engine however proved troublesome, with overheating problems occurring among other things. These problems were only solved after several improvements of the engine and so it took until the end of 1917 for the engine to attain its full operational maturity.[3]
