Super Corsair

In March 1944 a special low altitude version of the famous F4U Corsair was desired utilizing the 28 cylinder Pratt and Whitney R-4360 (4 row air cooled radial engine). Vought supplied an F4U-1 “birdcage” airplane to see if the airframe and engine was even compatible. The results were positive and the project was awarded to Goodyear to produce the F2G “Super” Corsair. 418- F2G-1 land based and 10- F2G-2 carrier based aircraft were ordered. (Only 5 production F2G-1, and 5 production F2G-2′s were known to have been built.) As many as nine prototypes were built as well.
Goodyear extensively modified a standard FG-1 airframe, designated the XF2G-1, to take advantage of the 50% increase in take-off power provided by the R-4360 engine. The vertical stabilizer of the F2G is 12 inches taller than on the standard Corsair and has an auxiliary rudder to counteract engine torque. An extended carburetor intake and all-round vision bubble-type canopy were installed as well.
Armament included wing-mounted installations of four (or six) 50 caliber machine guns, eight 5 inch (127 mm) rockets, or two 1,000 or 1,600 lb (450 or 725 kg) bombs. The internal fuel capacity was increased and hard points were provided to carry two droppable external tanks. Production F2G-1 aircraft were land-based fighters with manually folding wings and 14ft. Propellers; carrier based F2G-2 aircraft had hydraulic operated folding wings, 13ft. propellers, and arresting hooks.

Here is a list of known F2G variants:
• BuNo 02460: (Birdcage Canopy) to see if the airframe and engine were compatible. The tests proved successful and Goodyear Aircraft of Akron, Ohio was given the F2G program.
• BuNo 13471-XF2G-1: The first FG1 model to test the R-4360 engine. 5/31/44)
• BuNo 13472-XF2G-1: Same as 13471. (Cowl No. unknown) Stricken from Navy records 4/30/46.
• BuNo 14091-XF2G-1: The rear deck was modified to accept a P-47D bubble canopy. It still retained the R-2800 engine, FG1cowling and the 3 blade propeller.
• BuNo 14092-XF2G-1: Same as 14091 (092 on cowling) Tested at Akron and NAS Patuxent from 4/44 to 2/45. Stricken from Navy records 11/30/45.
• BuNo 14691-XF2G-1W The first aircraft manufactured as a true F2G- 1. It used the engine from 13471. First aircraft, to have the 12 inch auxiliary rudder.
• BuNo 14692-XF2G-1: (Blue and Yellow checkerboard cowl with Zinc Chromate nose ring) aircraft crashed and was destroyed in Akron, Ohio 12/12/45.
• BuNo 14693-XF2G-1: N5590N Race #94: First aircraft to have the extended carburetor intake. The aircraft was then tested at NAS Patuxent until it was obtained by Navy veteran Cook Cleland.
• BuNo 14694-XF2G-1: N91092 Race #18: The aircraft was tested at Mustin Field, PA. and NAS Patuxent from 10/45 to 5/47. Purchased by pilot Ron Puckett, raced in the 1947 and 1949 Nat. Air Races.
• BuNo 14695-XF2G-1: The final F2G prototype. Damaged by crane boom after crash landing in Akron OH and later scrapped.
• BuNo 88454-F2G-1: This was the first production F2G. It was tested at NAS Patuxent and NAS Norfolk from 1945 to 1948. Stricken from Navy records 5/31/48.
• BuNo 88455-F2G-1: Tested at Goodyear from 8/45 to 5/46. Stricken from Navy records 8/31/46. Scrapped.
• BuNo 88456-F2G-1: Tested at Port Columbus, Oh. and NAS Patuxent from 9/45 to 3/46. Stricken from Navy records 5/31/47. Scrapped.
• BuNo 88457-F2G-1: N5588N Race #84: Stricken from Navy records 4/30/47. Sold to owner Cook Cleland and flown by pilot Tony Janazzo in the 1947 Thompson Trophy Race.
• BuNo 88458-F2G-1: N5588N Race #57: Tested at Port Columbus, Oh. and NAS Patuxent from 10/45 to 7/46. Stricken from Navy records 1/48. The aircraft was purchased by Cook Cleland.
• BuNo 88459-F2G-2: Tested at Goodyear in Akron, OH and NAS Patuxent from 10/45 to 6/46. Ended up as ground target.
• BuNo 88460-F2G-2: Tested at NAS Norfolk and scrapped. Stricken from Navy records 5/31/48.
• BuNo 88461-F2G-2: Aircraft saw service with the fleet, NAS North Island San Diego in 1946. Stricken from Navy records 1/47.
• BuNo 88462-F2G-2: Aircraft saw service with the fleet at North Island, San Diego in 1946. Stricken from Navy records 5/47.
• BuNo 88463-F2G-2: N5577N Race #74: Used for training at NAS Jacksonville, Fla. Stricken from Navy records 2/28/47. Pilot Cook Cleland purchased the aircraft and flew it first place in the 1947 Thompson Trophy Race. It was also flown in the 1948 and 1949 Nat. Air Races by pilot Becker, who failed to finish. In 1953 The aircraft was purchased by Walter Soplata of Newbury, Oh. (I personally saw it at Walter’s place). In 1997, the Western Reserve Hist. Society of Cleveland, Oh. purchased the aircraft. The aircraft was then sent to Robert Odegaard of Kindred, N. D. for a static restoration. In 2007, No.74 was sold to Tom Ungurean of Coshocton, Ohio who instructed Odegaard Aviation to continue to restore the aircraft, but to flying condition. After 62 years, the aircraft flew again in public at the 2011 Reno Nat. Races. On Sept.12,2012, Robert Odegaard tragically died when the restored F2G Corsair crashed while practicing for a local air show.
