47 Ships Sunk by Kamikaze Aircraft. by Bill Gordon. Sources differ regarding the number of ships sunk by kamikaze aircraft during World War II. Inoguchi (1958, 211-34) lists the names of 34 ships sunk by kamikaze attacks, and Warner (1982, 323-34) gives the names of 57 ships sunk by special attack aircraft. However, an examination of other historical records indicates that both of these two lists do not have the correct number of ships sunk by kamikaze.
But the ship still has a story to tell. The U.S. Navy decommissioned the 30-year-old frigate Tuesday and with it shut the back cover on one of the most significant -- yet little-heralded -- stories in U.S. military history. The Simpson was the last modern U.S. Navy warship to sink an enemy vessel in action. Of the 272 ships in the fleet now, only one ship can claim a similar honor: the USS Constitution, now a showpiece in Boston harbor, which sank British vessels in the War of 1812. JUST WATCHED.
