The term "Super Corsair" refers to the Goodyear F2G-1 fighter, of which only fourteen examples were produced at the Goodyear plant in Akron before WWII ended in August 1945 and none of these saw combat. There were four prototypes and 10 production planes.
Basically, the plane was a further development of the famous F4U "Corsair" fighter that we all know. The aft fuselage was modified and a new "bubble" canopy was fitted, just like those on the P-51Ds and the P-47Ds, for increasing the pilot's visibility. Additionally, Goodyear installed a huge Pratt & Whitney R-4360 "Wasp Major" engine of 28 cylinders, capable of producing 3,500 hp.
Here's a photo of Odegaard's plane, which is one of the few survivors to date... Note the aft fuselage modifications and the shape of the canopy.
Cheers!
