The P.16 was a three-engine shoulder-wing monoplane of mostly metal construction, with inverted gull wings.

[1] In addition to bombs, its armament consisted of four 7.62-millimeter (0.3-inch) machine guns, of which two were mounted in the leading edge of the wing, one in a retractable dorsal turret, and one in the rear of the fuselage beneath the tail.

[1] The bombardier (bomb-aimer) manned a compartment set behind the nose engine on the underside of the fuselage.

The P.16 first flew in November 1934,[1] and an order for 12 aircraft was placed and then cancelled,[1] with preference given to the Piaggio P.32, which was produced from 1936 to 1939.
