USS New Jersey and the Fifth Fleet weathered the most powerful kamikaze attacks of the war, with over 355 kamikazes and 340 other planes attacking on April 6-7, and 185 kamikazes and a hundred or more other planes on April 11-12, 1945. Unlike the flammable carriers, the Iowa-class ships were near impervious to kamikazes. The New Jersey shot down at least one of the hundreds of planes downed by American ships and planes. Nonetheless, these initial waves sank three destroyers, three smaller warships, and two transports, and damaged two carriers and dozens of small ships, some beyond repair. These and other attacks cost Japan over a thousand aircraft and made April one of the bloodiest months in the war for the Navy. These suicide attacks, and the fanatical resistance by Japanese soldiers on Okinawa until June 22, helped convince new President Harry Truman that invasion of Japan itself would be exceedingly bloody and that use of the atomic bomb was a better alternative.
