The American sources claim that "kamikaze" sunk less ships than the Japanese say. But still, they agree that they did very important damage. According to a U.S. Air Force source, the "kamikaze" attackers sunk 34 Navy ships, damaged 368 others, killed 4,900 sailors, and wounded over 4,800. In a 2010 book, the historian Robin Rielly said that about 60 U.S. ships were sunk by kamikazes, and over 400 were damaged by them.
