During the inter-war years, Potez built a range of small passenger aircraft and a series of military reconnaissance biplanes that were also licence-built in Poland. In
1933, the firm bought flying boat manufacturer
CAMS. The company was
nationalized in
1936, following which it was merged with
Chantiers aéronavals Étienne Romano,
Lioré et Olivier,
CAMS and
SPCA in order to form the
Société nationale des constructions aéronautiques du Sud-Est (SNCASE) on 1 February 1937.{{citation Potez's factories in
Sartrouville and
Méaulte were taken over by
SNCAN and the
Berre factory went to
SNCASE. After
World War II, Potez was re-established as
Société des Avions et Moteurs Henry Potez at
Argenteuil but did not return to the prominence that the company enjoyed prior to nationalisation. In
1958, the company bought
Fouga to form
Potez Air-Fouga, but when Potez's last design, the
840 (a small turboprop airliner) failed to attract customers, it was forced to close. The remaining assets were purchased by
Sud-Aviation in
1967. ==Aircraft==
