The S.10 was the French version of the Arado Ar.396, built as the company's first post-war product. Twenty-eight produced.

The S.11 (50 built for the French Air Force) and S.111 were modified versions of the S.10 two-seat advanced trainer, fitted with Renault 125 engines (440kW SNECMA S-12-SO2-3H, French-built Argus As 411).

The S.12 was similar to the S.11 but was constructed entirely of metal; 52 S.12s were built for the French Air Force together with 58 S.121 lightweight derivatives. For use in Algeria, a number of S.111s and S.121s were modified to carry rockets and bombs for ground attack under the designations S.111A and S.121 A.
