Design and development

In 1929, the Regia Marina (Italian Royal Navy) awarded a contract to SIAI to produce the prototype of a new flying boat fighter for use as a catapult-launched aircraft aboard Condottieri-class cruisers. In response, SIAI designed the S.67, a wooden, single-seat, monoplane flying boat powered by a 313-kilowatt (420-horsepower) Fiat A.20 V12 liquid-cooled engine driving a three-bladed pusher propeller. The wing spars were attached to the fuselage, and the engine was mounted on steel tube struts above the hull, each attached to the engine mount by one pin. The S.67's armament consisted of two fixed, forward-firing 7.7-millimeter (0.303-inch) Vickers machine guns mounted in the bow. The S.67's design allowed a team of six men aboard a cruiser to erect it on its catapult and have it ready for launch within five minutes.[1]

Operational history

The S.67 made its first flight on 28 January 1930. Il Centro Sperimentali (The Experimental Center) began testing of the prototype in early March 1930, during which it crashed on 3 April 1930.[2]

Despite this unfortunate end to the testing program, SIAI received a production order for three more aircraft. One of these was cancelled, but the other two entered service with the 162ª Squadriglia (162nd Squadron) of the 88° Gruppo Caccia Marittima (88th Maritime Fighter Group). They were retired in 1935.[3]
