11/30/2010. The Ca.135 was designed to a Ministero dell'Aeronautica (Air Ministry) specification for a fast twin-engined medium bomber for the Regia Aeronautica Italiana (Italian Royal Air Force). The monoplane was of mixed construction, with a stressed-skin forward fuselage and a wood and fabric-covered steel-tube rear section, while the wooden wings were also covered with wood and fabric.
The prototype was first flown on April 1, 1935, but the Italian AF never operated the Ca.135. However, the type was exported to Peru, which received 32 aircraft, and the Hungarian AF acquired 180 examples. Soon the Ca.135 proved to be unsuitable as a bomber and the type was mainly used as a trainer and transport aircraft.
