					The US Navy’s first true 
					destroyers—seagoing flotilla craft whose main armament was 
					the torpedo—were the five ships of the
					“Smith” class, which 
					entered service around 1910. They represented a great 
					advance over earlier classes, some of which though rated 
					as destroyers were no more than lightly armed seagoing torpedo boats. The 
					"Smiths" were much larger, with a uniform armament of 5 x 
					3in guns plus 3 x 18in TT (single mounts; exchanged for 3 x 
					twin mounts in 1916.) The basic
					“Smith” design with 
					detail improvements was used for the next two classes, 
					totaling twenty-one ships. Then came the four ships of the
					“Cassin” class, the 
					first of the so-called thousand-tonners. These ships were 
					larger and faster than their immediate predecessors, with a 
					heavier armament: 4 x 4in guns and 8 x 18in TT (2 x 
					quadruple mounts). This progressive increase in destroyer 
					size and firepower reflected the Navy’s growing concern with 
					the creation of an integrated battle fleet. For that purpose 
					destroyers had to be robust and seaworthy, with a longer 
					range than hitherto. The 
					“Cassin” class was repeated with detail improvements 
					in the next two classes, totaling twelve ships. Thus by 1917 
					the Navy possessed a force of 44 reasonably modern 
					destroyers.

					The outbreak of World War I and the 
					increasing likelihood that the United States would become 
					involved in it led to congressional passage of the Navy Act 
					of 1916: a massive three-year construction program intended 
					to create “a Navy second to none.” In addition to new 
					battleships, battle cruisers and cruisers, the Act provided 
					for 50 new fleet destroyers. This was the genesis of the 
					Navy’s enormous wartime destroyer construction program that 
					ultimately produced 267 ships: the famous four-pipers of the
					'Wickes" and "Clemson" classes—so called because 
					of their four evenly spaced funnels.
					
					The six ships of the "Caldwell" 
					class served as prototypes for the mass-produced 
					four-pipers. Though much the same size as their 
					predecessors, they were fractionally faster and mounted a 
					heavier torpedo armament: 12 x 21in TT ( 4 x triple mounts, 
					two on each broadside). Otherwise, their armament was the 
					same as the preceding "Sampson" class: 4 x 4in guns plus 2 x 
					1-pounder AA guns. Visually, they were distinguished from 
					earlier classes by their flush deck (no forecastle break) 
					and their more extensive bridgework.
					
					To keep down weight, the 
					“Caldwells” were designed with a flush deck, relatively shallow draft,  a cruiser 
					stern, and a “drag” (keel sloping aft) to ensure that the 
					propellers and rudder were sufficiently deep in the water. 
					This made them wet forward and it was also found that they 
					had an undesirably large turning circle. The mass-produced 
					four-pipers therefore reverted to a level keel—which, 
					however, didn't fully solve these problems. It was found that 
					the major cause of the excessive turning circle was the 
					ships' tapered cruiser stern, which dug into the water when 
					the helm was put over. A larger rudder only partially 
					corrected this defect.
					
					The mass-produced four-pipers were 
					several hundred tons larger than the “Caldwells,” this to 
					accommodate more powerful machinery for a design speed of 35 
					knots, versus 30 knots for their predecessors. In service, 
					practical sea speed was 32-33 knots. Otherwise, they 
					were far from uniform in performance, having been 
					constructed by several shipbuilders with variations in 
					boilers and machinery. Endurance at cruising speed (15 
					knots) ranged from 2,400 to 4,500 nautical miles. Also the 
					Yarrow boilers with which some were fitted turned out to be 
					less than satisfactory in service.

					Only a handful of the four-pipers 
					were commissioned in time for service in World War One and 
					many were relegated to reserve status immediately after 
					completion. Some were scrapped under the terms of the London 
					Naval Treaty (1930), which restricted total tonnage in most 
					classes of warship. Others were disposed of because of the 
					rapid deterioration of their Yarrow boilers. Even so, 
					sufficient four-pipers remained to more than meet the needs 
					of the peacetime fleet, and it was not until 1933 that 
					Congress was willing to authorize new destroyers. By 1940, 
					93 four-pipers had been discarded with an additional twelve 
					lost in accidents, and 169 remained in service or in 
					reserve.
					
					Being available in such large 
					numbers, the four-pipers were considered suitable for 
					conversion to other roles. In 1939 USS Manley (DD-274) 
					of the "Caldwell" class became the prototype fast transport 
					(APD-1). Her TT were removed and replaced by cranes and 
					davits to handle four small landing craft, and her 
					superstructure was enlarged to accommodate 140 troops. 
					Ultimately 32 four-pipers were so converted. They proved 
					extremely useful in the Pacific during World War Two and saw 
					arduous service. Wartime APD armament was 3 x 3in/50 
					dual-purpose guns, 2 x 40mm Bofors AA guns (twin), 4 or 5 x 
					20mm AA, 2 x DC racks and 2 x DC throwers.
 
					
					
					
					USS Crosby (ADP-17; 
					formerly DD-164) of the Wickes Class after conversion to a

					Other four-pipers were converted 
					into light minelayers (DM; 8 units), high-speed minesweepers 
					(DMS; 18 units) or light seaplane tenders (AVP; 14 units). 
					For all these conversions the torpedo tubes were removed and 
					the original 4in guns were replaced by a variable number of 
					3in/50 DP guns, backed up by 40mm and 20mm light AA. As with 
					the APD conversions, DC racks and throwers were fitted, one 
					boiler was removed and one or two funnels were suppressed.
					
					Just prior to America’s entry in 
					World War II the Navy decided to refit another 37 
					four-pipers as antisubmarine escorts. They retained their 
					destroyer designation but like the other converted ships 
					they gave up a boiler and one funnel to increase fuel 
					stowage, reducing speed to 24–25 knots. The planned armament 
					was 6 x 3in/50 DP, six x 20mm AA, 2 x DC racks and 6 x DC 
					throwers, the latter replacing two of the four triple TT. 
					The last ten conversions, however, retained their original 
					4in guns.
					
					In 1940 fifty of the surviving 
					four-pipers (20 "Clemsons," 27 "Wickes," 3 "Caldwells") were 
					transferred to Britain’s Royal Navy (RN) in exchange for 
					99-year leases on naval and air bases in British Atlantic 
					and Caribbean colonies. Some were never commissioned in the 
					RN, being cannibalized to keep others operational. Those 
					commissioned received names of towns and cities common to 
					both the US and the UK and were known as the “Town” class. 
					Most were refitted with a British-style bridge and conn; 
					typical armament was 1 x 4in forward, 1 x 12-pounder HA aft, 
					4 x 20mm AA, 3 x 21in TT (1 x triple mount), 2 x DC racks 
					and a Hedgehog antisubmarine mortar. They were not 
					particular popular with the RN, being considered  
					cramped and hard to maneuver, but they filled the gap at a 
					time when British-built antisubmarine escorts were in short 
					supply. A number of the British four-pipers were 
					re-transferred to the Red Navy in 1944 to cover Soviet 
					claims for a share of the surrendered Italian fleet; they 
					were returned when equivalent Italian ships were delivered.

					The most famous of the British four-pipers was HMS 
					Campbeltown (I42), formerly USS Buchanan (DD-131) 
					of the "Wickes" class, which served as the centerpiece 
					of Operation Chariot (28 March 1942). This was a joint 
					attack by the Royal Navy and the Combined Operations 
					organization, whose objective was to destroy
					St. Nazaire's 
					 Normandie dry dock 
					on the Atlantic coast of 
					occupied France, thus preventing the German Navy from basing 
					any large ships in the area. 
					
					
					Campbeltown was stripped of most of her fittings, her 
					appearance was altered to resemble a German torpedo boat and 
					her bow was packed with 4.5 tons of high explosive. The idea 
					was to ram the ship into the dry dock under cover of a 
					commando raid, with the explosives timed to detonate after 
					the raiding force was withdrawn. The operation was a 
					success, though the cost was high, and the 
					Normandie dry dock was put out of 
					operation for the rest of the war.

					Though they were old by 1941 and 
					far less capable than the latest USN destroyers, the 
					four-pipers gave good and sometimes valiant service in a 
					multiplicity of roles. One, USS Reuben James 
					(DD-245), was the US Navy’s first World War II casualty. She 
					was torpedoed by the German U-552 near Iceland on 23 
					October 1941 while serving on escort duty. Of her crew of 
					143, only 44 enlisted sailors survived.  
					
					Another 
					four-piper, USS Ward (DD-139), fired the first shot 
					of the war with Japan. At about 0400 on the morning of 7 
					December 1941, while on patrol off the entrance to Pearl 
					Harbor, Ward received word of a periscope sighting 
					from the minesweeper USS Condor. The destroyer 
					immediately commenced a search. At 0637 lookouts sighted the 
					periscope of a submarine that appeared to be tailing a cargo 
					ship inbound to Pearl Harbor. Ward opened fire with 
					her 4in guns, scoring at least one hit, then ran in and 
					dropped depth charges, sinking what proved to be a Japanese 
					midget submarine. Ward was subsequently converted 
					into a fast transport, being recommissioned in February 1943 
					as ADP-16 and sent back to the Pacific. On 7 December 1944, 
					while patrolling off the Leyte (Philippines) invasion area, 
					she was attacked by several Japanese Kamikaze aircraft, one 
					of which struck her. The resulting fire could not be 
					controlled and after her crew was taken off, USS Ward 
					was sunk by gunfire from the destroyer USS O'Brien—whose 
					captain, Commander 
					
					William W. Outerbridge, had been the captain of the 
					Ward 
					
					on 7 December 1941.
					
					At the beginning of 
					the war many four-pipers were still serving as fleet 
					destroyers. For example, thirteen were with Destroyer 
					Squadron (DESRON) 29 in the Asiatic Fleet, based at Manila 
					Bay, the Philippines. DESRON 29 had four destroyer divisions 
					(DESDIV), each with four destroyers, plus a squadron 
					flagship. Shortly after hostilities began, 
					the commander of the Asiatic Fleet ordered a retreat to the 
					Malay Barrier, and in that area DESRON 29 fought several 
					actions. On 20 January USS Edsall 
					(DESDIV 57) sank the Japanese submarine 
					I-124 while on escort duty near Darwin, Australia. 
					DESDIV 59’s four destroyers (John D. Ford,
					Parrott, Paul Jones and Pope) 
					scored a neat success on 23 January, conducting a textbook 
					night torpedo attack against a Japanese invasion force off 
					Balikpapan. Four transports and a patrol vessel were sunk; 
					in return only Ford was slightly damaged. But the 
					Battle of the Java Sea and subsequent actions proved to be 
					the Asiatic Fleet’s swan song. Of the four-pipers, four were 
					sunk and one, Stewart, was damaged then captured by 
					the Japanese while in drydock. After being repaired and 
					rearmed, she was commissioned in the Imperial Japanese Navy 
					as No. 102. She survived the war and was returned to 
					the USN after Japan’s surrender, ultimately being expended 
					as a target. The eight survivors of DESRON 29 returned to 
					the US for conversion to escort destroyers, afterwards 
					serving in the Atlantic. 
					
					With the end of the war the 
					four-pipers passed into history. Most were decommissioned 
					and scrapped in 1945-47; none survive today. Manned largely 
					by Reserve crews from 1942 onward they had served the Navy 
					well in many roles, vital if not usually heroic. But the 
					most famous four-piper of all was one that never existed in 
					reality: USS Caine (DMS-22), Lieutenant Commander 
					Philip Francis Queeg commanding. The Caine was the 
					principal setting for Herman Wouk’s great novel of the US 
					Navy in World War II, 
					
					The Caine Mutiny. 
					Wouk, a Navy veteran of the war, had served aboard USS
					Zane (DMS-14) 
					and USS Southhard 
					(DMS-10). Like the fictional Caine
					both were 
					four-pipers converted into 
					destroyer-minesweepers. Lest we forget...
