Breda Ba.25

The Breda Ba.25 was an Italian two-seat biplane trainer designed and built by the Breda company.

It was the most widely used Italian basic trainer of the 1930s.

Initially designed as a single-seat aircraft, the prototype was later converted to a two-seat fuselage.

Flight testing of the two-seat variant was successful, and in late 1931 Regia Aeronautica ordered a series of 100 Ba.25 training aircraft.

The student and instructor sat in open tandem cockpits, although some versions had a single-bay cockpit.

The initial production order was completed by 1935, but demand for the aircraft increased and production for the Regia Aeronautica totalled 719 by the end of 1938.

The Ba.25 remained in service of the Regia Aeronautica as a training aircraft during World War II.  

Some of the aircraft were seized and handed over to the Allies.

Paraguay bought four Breda Ba.25, one of them a Ba.25 Idro.

They were used as primary trainers from 1939 to 1945.
