The Clemson-class ships were commissioned by the United States Navy from 1919 to 1922, built by Newport News Shipbuilding & Dry Dock Company, New York Shipbuilding Corporation, William Cramp and Sons, Bethlehem Steel Corporation, Mare Island Naval Shipyard, Norfolk Naval Shipyard and Bath Iron Works, some quite rapidly. The Clemson class was a minor redesign of the Wickes class, and was the last pre-World War II class of flush-decker destroyers to be built for the United States. Until the Fletcher-class destroyer, the Clemsons were the most numerous class of destroyers commissioned in the United States Navy, and were known colloquially as "flush-deckers", "four-stackers", or "four-pipers."
As finally built, the Clemson class would be a fairly straightforward expansion of the Wickes-class destroyers. While the Wickes class had given good service there was a desire to build a class more tailored towards the anti-submarine role, and as such several design studies were completed, mainly about increasing the ships' range. These designs included a reduction in speed to between 26 and 28 knots by eliminating two boilers, freeing up displacement for depth charges and more fuel. This proposal foreshadowed the destroyer escorts of World War II.
Upgrading the gun armament from 4" to 5" guns was also considered. In addition, the tapered stern of the Wickes-class destroyers resulted in a large turning radius and a correction to this defect was also sought, although this was not corrected in the final design. In the end the General Board decided the 35 knot speed be retained so as to allow the Clemson class to be used as a fleet escort. The pressing need for destroyers overruled any change that would slow production compared to the proceeding Wickes class. Wing tanks for fuel oil were installed on either side of the ships to increase the operational range. This design choice meant the fuel oil would be stored above the waterline and create additional vulnerability, but the Navy felt a 4900 nm range was worth the risk. Additional improvements included provisions for 5" guns to be installed at a later date, an enlarged rudder to help reduce the turn radius, and an additional pair of 3" anti-aircraft guns on the deck-house.
The main armament was the same as the Wickes class: 4 × 4"/50 caliber guns (102 mm) and 12 × 21" torpedo tubes (533 mm). The Mark 8 torpedo was initially equipped, and probably remained the standard torpedo for this class, as 600 Mark 8 torpedoes were issued to the British in 1940 as part of the Destroyers for Bases Agreement.
Although the design provided for two anti-aircraft (AA) guns, most ships carried a single 3 inch 23 caliber (76 mm) AA gun, typically on the aft deckhouse. A frequent modification was reversing the aft 4" gun with the 3" gun to make more room for the depth charge tracks. Anti-submarine (ASW) armament was added during or after construction. Typically, two depth charge tracks were provided aft, along with a Y-gun depth charge projector forward of the aft deckhouse.
Despite the provision for 5" guns, only seven ships were built with an increased gun armament. USS Hovey (DD-208) and USS Long (DD-209) had twin 4"/50 mounts for a total of eight guns, while DD 231-235 had four 5"/51 caliber guns (127 mm) in place of the 4" guns.
As with the preceding class, the fleet found that the tapered stern, which made for a nice depth charge deployment feature, dug into the water and increased the turning radius. While the increased rudder size helped, the answer would be in a redesigned stern. They were reported to be prone to heavy rolling in light loaded conditions. The flush deck gave the hull great strength but this also made the deck very wet.
Fourteen ships of the class were involved in the Honda Point Disaster (aka Point Pedernales) in 1923, of which seven were lost.
Many never saw wartime service, as a significant number were decommissioned in 1930 and scrapped as part of the London Naval Treaty. About 40 Clemson class DDs with Yarrow boilers were scrapped or otherwise disposed of in 1930-31, as these boilers wore out quickly in service. Flush-deckers in reserve were commissioned as replacements. In 1936 only some 169 of the flush deck destroyers would be left, four of them Caldwell class and the rest of them Wickes and Clemson class.
Nineteen were transferred to the Royal Navy in 1940 as part of the Destroyers for Bases Agreement where they became part of the Town class. Others were upgraded or converted to high speed transports or seaplane tenders and served through World War II.
Most ships remaining in service during World War II were rearmed with dual-purpose 3"/50 caliber guns to provide better anti-aircraft protection. The AVD seaplane tender conversions received 2 guns; the APD high-speed transport, DM minelayer, and DMS minesweeper conversions received 3 guns, and those retaining destroyer classification received 6. Their original low-angle 4"/50 caliber guns (Mark 9) were transferred to Defensively Equipped Merchant Ships for anti-submarine protection. For the ships converted to minesweepers, the twelve 21" (533 mm) torpedo tubes were replaced by minesweeping gear.
USS Stewart (DD-224) was scuttled at Soerabaja on March 2, 1942, following the surrender of the Dutch East Indies to the Japanese. She was raised, repaired and recomissioned as a patrol boat by the Imperial Japanese Navy. She was recaptured by the US Navy following the end of World War II. In addition, 17 Clemson-class destroyers were lost during the war.
The wrecks of two Clemson class destroyers remain in the San Francisco Bay area, USS Corry (DD-334) a few miles north of Mare Island Navy Yard on the Napa River, and USS Thompson (DD-305) in the southern part of the Bay, used as a bombing target in World War II.
