History

It was developed from the SM.62bis, keeping practically the same wings, tail and fuselage but with a different type of Handley Page flap. The prototype first flew at the end of 1932.

Variants

The prototype had an enclosed cockpit for the two pilots, which was replaced by an open cockpit on the production model.

Where you'll see it

Forty-nine were completed, 32 by Piaggio and 17 by SIAI. It equipped four squadriglie of the Regia Aeronautica until 1938, when the CANT Z.501 replaced it, and some later served in air-sea rescue.
