The Breguet 482 was born
from the program A21 of December 1936. This first concerned a
project of B4 twin-engined engines equipped with engines Gnome
Rhone (1934), program then extended to four-engines. The Breguet
482 was in competition with the Bloch 135, another four-engine.
The Breguet Br 482 was equipped with Hispano-Suiza 12Y-20/21 engines.
Although commissioned in
May 1938, construction of the two prototypes did not begin until
1939, with new Hispano-Suiza HS 12 Y-50/51 engines of 1100 CV.
The aircraft was of modern design, all steel with a monocoque
fuselage.
Surprised by the German
advance, the two prototypes were evacuated: one to North Africa,
where it was destroyed during the Allied landing in 1942, the
other to Toulouse where it was stored throughout the occupation.
It was not until 1947
that the latter was completed, and that he made his first flight.
It was then used as a test aircraft.
