Since 1926–1928 the Lorraine works of Argenteuil (Société Nationale de Construction de Moteurs since 1930) have constructed a family of inline engines, each comprising two or three cast blocks of cylinders, a supercharger, two camshafts per cylinder block and reduction gear. Subsequent types were named after birds. The Sterna (a genus of terns) of 1936 was an development of earlier Petrel V-engine. The engine was used in a Dutch experimental fighter designated the Koolhoven F.K.55.
