The Japanese Navy is a different story—they know what they are doing. They have Yamamoto. They have torpedoes that actually explode when they strike their targets, in stark contrast to the American models which do nothing but scratch the paint of the Japanese ships and then sink apologetically. Yamamoto just made another attempt to wipe out the American fleet off the Santa Cruz Islands, sank Hornet and blew a nice hole in Enterprise . But he lost a third of his planes. Watching the Japanese rack up losses, Waterhouse wonders if anyone in Tokyo has bothered to break out the abacus and run the numbers on this Second World War thing.
