Societe Nationale de Constructions Aeronautiques du Centre
In France, the Socialist Government of the so-called Popular Front brought all the companies building military aircraft, aero engines and armament under its control in 1936. The immediate result was the socialized oblivion of such established companies as Marcel Bloch, Bleriot, Nieuport, Potex, Dewoitine, Hanriot and Farman within half a dozen nationalized groups or Societies Nationales, named according to their geographical location (Nord, Ouest, Centre, Midi and so on).
Farman and Hanriot formed the new Societe Nationale de Constructions Aeronautiques du Centre, known as SNCAC or Aerocentre.
After World War II, although four of the nationalized groups continued operating under state control, private companies were allowed to resume the design and manufacture of both civil and military aircraft. Aerocentre conducted the final development of the Farman line of four-engined heavy bombers which had engines in tandem underslung pairs, derived from the F.211 of 1931. Aerocentre went into liquidation during 1949, its plants and work being shared by SNCAN (Nord), SNCASO (Sud-Ouest) and engine form SNECMA.
