The Akutan Zero was very important to the American war effort. Some said it may have been "one of the greatest prizes of the Pacific war". Japanese historian Masatake Okumiya thought that losing the Akutan Zero to the Americans was similar to Japan losing the Battle of Midway. He said it made Japan lose the war sooner. On the other hand, John Lundstrom is among those who do not agree with "the contention that it took dissection of Koga's Zero to create tactics that beat the fabled airplane".
