USS Mervine (DD-322)

USS Mervine (DD-322) was a Clemson-class destroyer in service with the United States Navy from 1921 to 1930. She was scrapped in 1931.

Description
The Clemson class was a repeat of the preceding Wickes-class destroyer although more fuel capacity was added. The ships displaced 1290 LT at standard load and 1389 LT at deep load. They had an overall length of 314 ft, a beam of 30 ft and a draught of 10 ft. They had a crew of 6 officers and 108 enlisted men.

Performance differed radically between the ships of the class, often due to poor workmanship. The Clemson class was powered by two steam turbines, each driving one propeller shaft, using steam provided by four water-tube boilers. The turbines were designed to produce a total of 27000 shp intended to reach a speed of 35 kn. The ships carried a maximum of 371 LT of fuel oil which was intended to give these a range of 2500 nmi at 20 kn.

The ships were armed with four 4-inch (102 mm) guns in single mounts and were fitted with two 1-pounder guns for anti-aircraft defense. In many ships a shortage of 1-pounders caused them to be replaced by 3-inch (76 mm) guns. Their primary weapon, though, was their torpedo battery of a dozen 21 inch (533 mm) torpedo tubes in four triple mounts. They also carried a pair of depth charge rails. A "Y-gun" depth charge thrower was added to many ships.

Construction and career
Mervine, named for Rear Admiral William Mervine, was laid down at the Union Plant, Bethlehem Shipbuilding Corporation, San Francisco, California, 28 April 1919; launched 11 August 1919; sponsored by Miss Eileen D. McCarthy; and commissioned 28 February 1921. Mervine, built on the west coast, joined the Pacific Fleet at San Diego, California after shakedown to remain a unit of that fleet’s destroyer force for her entire career. With few interruptions she operated off the west coast for most of that 9-year period. Her participation in Fleet Problems I (1923) and II, III, and IV (1924) took her to the Panama Canal Zone and the Caribbean, while others, VI (1926), VII (1928), and IX (1929), saw her in maneuvers off Central America and near Hawaii. Crossing the Pacific only twice in her career, she completed a good will trip to Samoa and Australia in the summer of 1925 (1 July to 26 September).

On 18 September 1929 she entered San Diego for the last time. Decommissioned 4 June 1930, she was towed to Mare Island on the 14th for scrapping and struck from the Naval Register 3 November 1930.
