Robert Wayne Duncan (20 December 1920 – 12 October 2013) was an American flying ace in the Pacific theatre of World War II.

After a Mitsubishi Zero crashed in the Aleutian Islands, the U.S. Navy reconstructed the plane in order to study and test it to find its weaknesses in aerial combat.

[1][2] Duncan, then an Ensign,[1] scored his first and second aerial victories in the Hellcat on 5 October 1943, the second being Japanese flying ace Warrant Officer Toshiyuki Sueda, who previously had downed nine American aircraft, mostly Grumman Wildcats.

Sueda had previously lured Wildcats into a trap by flying into a vertical loop and waiting for them to stall out before diving down to shoot them.

[7] During the Korean War, Duncan was stationed to a jet squadron on the USS Boxer, and cumulatively (with WWII) flew 100 combat missions in a Grumman F9F Panther.
