USS Mannert L. Abele (DD-733), was an Allen M. Sumner-class destroyer of the United States Navy. The destroyer was sunk on April 12, 1945, near Okinawa with 84 casualties. It was the first US warship to be damaged or sunk by the rocket powered Yokosuka MXY7 Ohka suicide flying bomb.

The Allen M. Sumner class was a group of 58 destroyers built by the United States during World War II. Another twelve ships were completed as destroyer minelayers. The class was named for Allen Melancthon Sumner, an officer in the United States Marine Corps. Often referred to as simply the Sumner, this class was distinguished from the previous Fletcher class by their twin 5-inch/38 caliber gun mounts, dual rudders, additional anti-aircraft weapons, and many other advancements. The Allen M. Sumner design was extended 14 feet (4.3 m) amidships to become the Gearing class, which was produced in larger numbers but did not see significant service in World War II.
