This aircraft was built to satisfy a U.S. Navy requirement for a new catapult-launched scout seaplane to be deployed from cruisers and battleships. Although previous aircraft of that type had been two-seaters, the Navy had decided that all future aircraft of that sort would be single-seaters. For that reason this aircraft superficially resembled a single-seat fighter, but it was definitely not one. The Navy production contract went to the Curtiss SC-1 "Seahawk" instead of the Edo seaplane. However, as helicopters began to come into use late in World War II, the Curtiss "Seahawk" became the last such seaplane to be ordered by the Navy. By the early 1950s catapult-launched seaplanes such as this had completely disappeared from Navy warships.

Edo was a company that made floats for seaplanes. I believe this was their only foray into aircraft design as such.

This may look like a fighter but appearances can be deceiving. It was meant to be a catapult-launched scout seaplane, for operation from cruisers or battleships. The engine was the 600-hp, air-cooled, inverted-V-12 Ranger. The only other aircraft that engine was used in was the highly unsatisfactory Curtiss SO3C Seamew, one of the worst aircraft in the Navy's inventory at that time.

I think it look's more like sleek F6F Hellcat.

The engine was a Ranger V-770

This was built by EDO.float and pontoon manufaturer in College Point,N.Y. It's engine was inverted and during a test flight the engine blew a cylinder and the plane was forced to land in the East River /Long island sound, I beleive only one plane was made and it flew in spring of 1945,to late for WW2. I lived in College Point at the time and saw it fly a few times,it was very slow and it had to be very careful as LaGuardia Field was just acroos the water from where EDO was located.

Almost looks like a float-plane conversion of a P-40 Warhawk...I never did like the three-float system though...a bit ungainly...
