The USS Mannert L. Abele was sunk by a "human-guided kamikaze bomb" off the coast of Okinawa, Japan during WWII. The crew was forced to abandon ship and was eventually rescued by other U.S. Navy ships in the area. The Abele is the first U.S. Navy ship to be sunk by a kamikaze attack and is the only U.S. Navy destroyer sunk during WWII that has yet to be found.
