Kenney was probably one of the ablest commanders of the war. An innovator he is credited with coming up with the idea of arming B-25's mitchells with extra .50 cal MG for use against transports and for AA suppression. He is also credited with a 100 lb white phosphorus bomb called the "kenney Cocktail" used as bunker busters much like the later napalm bombs. He is also erroneously credited with the development of skip bombing which was used in the anti-shipping role in the SWP.
What I like about Kenney is that he immediately put MacArthur's CoStaff General Sutherland in his place when he arrived in the SWP theater to take over for the ineffectual general Brett. In his first day of duty Sutherland tried to tell Kenney how to run the Far East Air Force and Kenney got a piece of paper, drew a large circle on the paper and then a small dot in the middle of the circle. Kenney then told Sutherland that what kenney knew about flying was the large circle and what Sutherland knew about flying was the dot. Hehe....
IMO, kenney was very impressive as a commander of the Far East Air Force. he was commander of the 5th AF that concentrated on offensive action; the Royal Australina Air Force in charge of defending Australia; 13th Air Force in the support role; US 3rd and 7th carrier based fleets; 7th Fleet B-29's of the 20th AF and later in the war RAAF in offensive operations.
kenney was known to exxagerate a bit in making claims of destroyed and damaged japanese targets but that's more to do with trusting too much the claims made by pilots. other than this minor deficiency Kenney should be up there with the LeMay's, pete Quesada's, Doolittles, Eaker of American aviation during WWII.
