Piaggio P.6

In 1927 two parallel,designs were developed to meet an Italian naval requirement for a two-seat catapult-launched seaplane. One was a small flying-boat, the Piaggio P.6bis powered by a single 194kW Isotta Fraschini V.6 engine mounted between the wings and driving a pusher propeller; the other was the P.6 floatplane with a large central float, two wing-tip stabilising floats, and a 288kW A.20 engine in the nose. The two aircraft had identical wing structure, with rigid strut bracing, and each mounted a single defensive machine-gun, that of the flying-boat in the bow, and the floatplane's in the rear cockpit.

The P.6ter of 1928 was similar to the P.6, but had an engine boosted to 306kW to provide a maximum speed of 195km/h. Wing span was 13.50m and maximum take-off weight 2360kg. A batch of 15 P.6ter floatplanes was built, and the type was used for a period aboard several Italian capital ships and cruisers.
