The Battle of The Philippine Sea took place in June 1944 when the Japanese attempted to stop the American invasion of the Marianas. The Japanese fleet included 5 fleet carriers and 4 light carriers against 7 American Fleet carriers and 8 light carriers. The American carriers carried over 900 planes as opposed to 450 carrier and 300 land based aircraft for the Japanese. Despite having some advantages, such as a superior range for their aircraft, the Japanese were decisively defeated due to superior American training. The slaughter of Japanese pilots was so great: it was described as a "turkey shoot."
