Overall, more than 80 Japanese aircraft were dispatched against Saipan and Tinian between November 1944 and the end of the offensive in February 1945. The Japanese destroyed 11 B-29s, caused major damage to eight and minor damage to another 35. American casualties were 45 dead and over 200 wounded. USAAF fighters
