The Clemson class was a repeat of the preceding Wickes class although more fuel capacity was added. The ships displaced 1,290 long tons (1,310 t) at standard load and 1,389 long tons (1,411 t) at deep load. They had an overall length of 314 feet 4 inches (95.8 m), a beam of 30 feet 11 inches (9.4 m) and a draught of 10 feet 3 inches (3.1 m). 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 27,000 shaft horsepower (20,000 kW) intended to reach a speed of 35 knots (65 km/h; 40 mph). The ships carried a maximum of 371 long tons (377 t) of fuel oil which was intended gave them a range of 2,500 nautical miles (4,600 km; 2,900 mi) at 20 knots (37 km/h; 23 mph).
The ships were armed with four 4-inch (102 mm) guns in single mounts and were fitted with two 1-pdr (28 mm) 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 (530 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
Coghlan, named for Joseph Coghlan, was launched 16 June 1920 by Bethlehem Shipbuilding Corporation, San Francisco; sponsored by Mrs. G. Coghlan; and commissioned 31 March 1921, Lieutenant (junior grade) C. Hupp in command. Coghlan arrived at Charleston, South Carolina, 28 December 1921 for operations in East Coast and Caribbean waters. Coghlan took part in the funeral ceremonies for President Warren G. Harding at Washington (7–9 August 1923) and served as a plane guard in the North Atlantic (24 July – 6 September 1924) during the Army's round the-world flight.
From 18 June 1925 to 11 July 1926 she served with U.S. Naval Forces Europe in the Mediterranean protecting American interests. The destroyer returned to her cruising along the east coast and in the Caribbean, served as an exhibition vessel at the Philadelphia Sesquicentennial Exposition during the summer of 1926, cruised with the Special Service Squadron off Nicaragua (3 February – 31 March 1927), and took part in the Presidential Fleet Review, in Hampton Roads, 4 June 1927.
