Destroyer Division 20

Destroyer Division 20 was a destroyer formation of the United States Navy that saw extensive combat service during World War II. Established in 1943, the division operated primarily in the Pacific Theater of Operations, participating in many of the major campaigns of the Pacific War. Its ''Fletcher''-class destroyers were integral to fast carrier task force operations, providing anti-aircraft screening and anti-submarine protection. The unit was deactivated following the conclusion of hostilities in 1945.

History

The division was established in mid-1943 as part of the massive wartime naval expansion to support offensive operations across the Pacific Ocean. It was assigned to the United States Pacific Fleet under the overall command of Admiral Chester W. Nimitz. The formation of new destroyer divisions like this one was critical for organizing the rapidly growing fleet of modern warships being deployed against the Empire of Japan. Its creation coincided with the shift to island-hopping campaigns following victories at the Battle of Guadalcanal and the Battle of Midway.

Composition

Destroyer Division 20 was consistently composed of four ''Fletcher''-class destroyers, a class renowned for its balance of firepower, speed, and endurance. These ships were typically organized into a division as part of a larger destroyer squadron, such as Destroyer Squadron 10. The standard armament of these vessels included five 5-inch/38 caliber dual-purpose guns, ten 21-inch torpedo tubes, and an extensive suite of 40 mm and 20 mm anti-aircraft weapons. This configuration made them ideally suited for the multi-threat environment of the Pacific War.

Operational history

Upon becoming operational, the division was immediately thrust into the central Pacific campaign, providing screening and escort duties for fast carrier task forces. It participated in the Gilbert and Marshall Islands campaign, including the Battle of Tarawa and the Battle of Kwajalein. The division supported the Marine Raiders during the Battle of Eniwetok and provided naval gunfire support for the United States Army at the Battle of Saipan. During the Battle of the Philippine Sea, its ships were part of the defensive screen protecting the Task Force 58 carriers from aerial attack.

The division continued in this vital screening role through the later stages of the war. It was present during the Battle of Leyte Gulf, operating in the vicinity of the Sibuyan Sea and off Samar. It later supported the Invasion of Lingayen Gulf and the Battle of Iwo Jima, where its guns bombarded Japanese shore positions. Its final major combat operations were during the Battle of Okinawa, where it defended against relentless kamikaze attacks. Following the Surrender of Japan, the division assisted with occupation duties before being decommissioned.

Commanding officers

The division was led by a succession of experienced destroyer officers who held the rank of Commander. These officers were typically veterans of earlier naval engagements in the Solomon Islands campaign or the Battle of the Atlantic. Command rotated among the commanding officers of the division's constituent destroyers, as was standard practice for such units. Their leadership was crucial during complex fleet operations and intense surface actions like the Naval Battle of Guadalcanal.

Ships of the division

The division's composition evolved slightly over its service life, but its core consisted of the following Fletcher-class destroyers: * USS ''Halsey Powell'' (DD-686) * USS ''Uhlmann'' (DD-687) * USS ''Benham'' (DD-796) * USS ''Cushing'' (DD-797) These ships were all built at major shipyards such as Bethlehem Steel and launched in 1943. Each vessel earned multiple battle stars for its wartime service across the Pacific Theater of Operations, from the Aleutian Islands to the Japanese archipelago.
