Sinking History
On April 12, 1945 in the afternoon while on radar picket duty off northern Okinawa targeted by kamikaze planes. At 1:45pm three Vals attacked but were driven off with one shot down At 2:00pm 15–25 planes were observed but did not enter gun range, aside from one light bomber that was damaged.

At 2:40pm, three Zeros approached the destroyer with one driven off and another shot down. The third was hit by anti-aircraft fire but still managed to crash into the starboard side and penetrated into the aft engine room and exploded. The destroyer lost control and began to slow with a broken keep midship and all guns and directors lost power. At 2:46pm hit by MXY7 Ohka (Baka) on the starboard side at the waterline abreast the forward fire room and instantly cut all power. Almost immediately, the damaged destroyer broke into two pieces that rapidly sank at roughly Lat 27°25'N, Long 126°59'E. A total of 84 of her crew went down with the ship. The destroyer was the first U.S. Navy hit and sunk by an Ohka (Baka). For his actions, Cdr Parker earned the Navy Cross.
