The Fletcher class was a class of destroyers built by the United States during World War II. The class was designed in 1939, as a result of dissatisfaction with the earlier destroyer leader types of the Porter and Somers classes. Some went on to serve during the Korean War and into the Vietnam War.
The Atlanta-class cruisers were eight United States Navy light cruisers which were designed as fast scout cruisers, flotilla leaders, or destroyer leaders, but which proved to be effective anti-aircraft cruisers during World War II. They were also known as the Atlanta-Oakland class. The Atlanta class originally had 16 x 5-inch (127 mm)/38 caliber guns in eight two-gun turrets, arranged with three superfiring turrets forward, three more superfiring aft and two waist mounts, one port and one starboard, giving the first four Atlanta-class cruisers the heaviest anti-aircraft armament of any cruiser of World War II. The last four ships of the class, starting with Oakland, had a slightly revised armament with a reduced main gun battery - the waist turrets being deleted - as they were further optimized for anti-aircraft fire in light of war experience.
The Benham class of ten destroyers was built for the United States Navy (USN). They were part of a series of USN destroyers limited to 1,500 tons standard displacement by the London Naval Treaty and built in the 1930s. The class was laid down in 1936-1937 and all were commissioned in 1939. Much of their design was based on the immediately preceding Gridley and Bagley-class destroyers. Like these classes, the Benhams were notable for including sixteen 21-inch (533 mm) torpedo tubes, the heaviest torpedo armament ever on US destroyers. They introduced a new high-pressure boiler that saved space and weight, as only three of the new boilers were required compared to four of the older designs. The class served extensively in World War II in the Atlantic, Mediterranean, and Pacific theaters, including Neutrality Patrols in the Atlantic 1940-1941. Sterett received the United States Presidential Unit Citation for the Battle of Guadalcanal and the Battle of Vella Gulf, and the Philippine Republic Presidential Unit Citation for her World War II service. Two of the class were lost during World War II, three were scrapped in 1947, while the remaining five ships were scuttled after being contaminated from the Operation Crossroads atomic bomb tests at Bikini Atoll in the Pacific.
The Wickes-class destroyers were a class of 111 destroyers built by the United States Navy in 1917–19. Together with the six preceding Caldwell-class and following 156 subsequent Clemson-class destroyers, they were grouped as the "flush-deck" or "four-stack" type. Only a few were completed in time to serve in World War I, including USS Wickes, the lead ship of the class.
The Allen M. Sumner class was a group of 58 destroyers built by the United States during World War II. Another twelve ships were completed as destroyer minelayers. The class was named for Allen Melancthon Sumner, an officer in the United States Marine Corps. Often referred to as simply the Sumner, this class was distinguished from the previous Fletcher class by their twin 5-inch/38 caliber gun mounts, dual rudders, additional anti-aircraft weapons, and many other advancements. The Allen M. Sumner design was extended 14 feet (4.3 m) amidships to become the Gearing class, which was produced in larger numbers but did not see significant service in World War II.
Four destroyers in the United States Navy comprised the Cassin class. All served as convoy escorts during World War I. The Cassins were the first of five "second-generation" 1000-ton four-stack destroyer classes that were front-line ships of the Navy until the 1930s. They were known as "thousand tonners" for their normal displacement, while the previous classes were nicknamed "flivvers" for their small size, after the Model T Ford.
The Aylwin class was a class of four destroyers in the United States Navy; all served as convoy escorts during World War I. The Aylwins were the second of five "second-generation" 1000-ton four-stack destroyer classes that were front-line ships of the Navy until the 1920s. They were known as "thousand tonners". All were scrapped in 1935 to comply with the London Naval Treaty.
The Fubuki-class destroyers were a class of twenty-four destroyers of the Imperial Japanese Navy. The Fubuki class has been described as the world's first modern destroyer. The Fubuki class set a new standard not only for Japanese vessels, but for destroyers around the world. They remained formidable opponents to the end of World War II, despite being much older than many of their adversaries.
The O'Brien class of destroyers was a class of six ships designed by and built for the United States Navy shortly before the United States entered World War I. The O'Brien class was the third of five classes of destroyers that were known as the "thousand tonners", because they were the first U.S. destroyers over 1,000 long tons (1,016 t) displacement.
The Sampson-class destroyers served in the United States Navy during World War I. Commissioned in 1916 and 1917, the class was a modification of the O'Brien and Tucker classes, with the number of 21-inch (533 mm) torpedo tubes increased from four twin-mounts to four triple-mounts. The Sampsons were the final six ships of the 26 "thousand tonner" destroyers. They were the largest and most heavily armed of the "thousand tonners", and the subsequent "flush deck" classes differed mainly in hull design and the engineering plant.
The Benson class was a class of destroyers of the U.S. Navy built 1939–1943. The thirty 1,620-ton Benson-class destroyers were built in two groups. The first six were authorized in fiscal year 1938 (FY38) and laid down at Bethlehem Steel, Quincy, Massachusetts, and three naval shipyards. The remaining 24 "repeat Bensons" were authorized in 1940–42 and built at four Bethlehem Steel yards. They were laid down after the first group was commissioned. These plus the "repeat Livermores" were also known at the time as the Bristol class. During World War II the Bensons were usually combined with the Livermores as the Benson-Livermore class; this persisted in references until at least the 1960s. In some references both classes are combined and called the Benson class. The Benson- and Gleaves-class destroyers were the backbone of the pre-war Neutrality Patrols and brought the action to the enemy by participating in every major campaign of the war.
The Gleaves-class destroyers were a class of 66 destroyers of the United States Navy built 1938–42, designed by Gibbs & Cox. The first ship of the class was USS Gleaves. They were the destroyer type that was in production for the US Navy when the United States entered World War II.
The Akatsuki-class destroyer was a class of four destroyers of the Imperial Japanese Navy. According to most sources, they are regarded as a sub-class of the Fubuki class, partly because the Imperial Japanese Navy itself kept the improvements made a secret, and did not officially designate these four destroyers as a separate class.
The Caldwell class was a class of six "flush deck" United States Navy destroyers built during World War I and shortly after. Four served as convoy escorts in the Atlantic; the other two were completed too late for wartime service. Two were scrapped during the 1930s, but four survived to serve throughout World War II, three of these in service with the Royal Navy under the Destroyers for Bases Agreement and the fourth as a high speed transport.
The Farragut-class destroyers were a class of eight 1,365-ton destroyers in the United States Navy and the first US destroyers of post-World War I design. Their construction, along with the Porter class, was authorized by Congress on 29 April 1916, but funding was delayed considerably. Limited to 1,500 tons standard displacement by the provisions of the London Naval Treaty of 1930, the ships were laid down beginning in 1932 and were completed by 1935. After 12 years since the last of the previous class of American destroyers was commissioned, the Farraguts were commissioned in 1934 and 1935.
The Porter-class destroyers were a class of eight 1,850-ton large destroyers in the United States Navy. Like the preceding Farragut-class, their construction was authorized by Congress on 26 April 1916, but funding was delayed considerably. They were designed based on a 1,850-ton standard displacement limit imposed by the London Naval Treaty; the treaty's tonnage limit allowed 13 ships of this size, and the similar Somers class was built later to meet the limit. The first four Porters were laid down in 1933 by New York Shipbuilding in Camden, New Jersey, and the next four in 1934 at Bethlehem Steel Corporation in Quincy, Massachusetts. All were commissioned in 1936 except Winslow, which was commissioned in 1937. They were built in response to the large Fubuki-class destroyers that the Imperial Japanese Navy was building at the time and were initially designated as flotilla leaders. They served extensively in World War II, in the Pacific War, the Atlantic, and in the Americas. Porter was the class' only loss, in the Battle of the Santa Cruz Islands on 26 October 1942.
The Gridley-class destroyers, named for Charles Vernon Gridley, were a class of four 1500-ton destroyers in the United States Navy. They were part of a series of USN destroyers limited to 1,500 tons standard displacement by the London Naval Treaty and built in the 1930s. The first two ships were laid down on 3 June 1935 and commissioned in 1937. The second two were laid down in March 1936 and commissioned in 1938. Based on the preceding Mahan-class destroyers with somewhat different machinery, they had the same hull but had only a single stack and mounted sixteen 21 inch (533 mm) torpedo tubes, an increase of four. To compensate for the increased torpedo armament weight, the gun armament was slightly reduced from five 5"/38 caliber guns (127 mm) to four. USS Maury (DD-401) made the highest trial speed ever recorded for a United States Navy destroyer, 42.8 knots. All four ships served extensively in World War II, notably in the Solomon Islands and the Battle of the Philippine Sea, with Maury receiving a Presidential Unit Citation.
The Bagley class of eight destroyers was built for the United States Navy. They were part of a series of USN destroyers limited to 1,500 tons standard displacement by the London Naval Treaty and built in the 1930s. All eight ships were ordered and laid down in 1935 and subsequently completed in 1937. Their layout was based on the concurrently-built Gridley class destroyer design and was similar to the Benham class as well; all three classes were notable for including sixteen 21 inch torpedo tubes, the heaviest torpedo armament ever on US destroyers. They retained the fuel-efficient power plants of the Mahan-class destroyers, and thus had a slightly lower speed than the Gridleys. However, they had the extended range of the Mahans, 1,400 nautical miles (2,600 km) farther than the Gridleys. The Bagley class destroyers were readily distinguished visually by the prominent external trunking of the boiler uptakes around their single stack.
The Somers-class destroyer was a class of five 1850-ton United States Navy destroyers based on the Porter class. They were answers to the large destroyers that the Japanese navy was building at the time, and were initially intended to be flotilla leaders. They were laid down from 1935–1936 and commissioned from 1937–1939. They were built to round-out the thirteen destroyers of 1,850 tons standard displacement allowed by the tonnage limits of the London Naval Treaty, and were originally intended to be repeat Porters. However, new high-pressure, high-temperature boilers became available, allowing the use of a single stack. This combined with weight savings allowed an increase from two quadruple center-line torpedo tube mounts to three. However, the Somers class were still over-weight and top-heavy. This was the first US destroyer class to use 600 psi (4,100 kPa) steam superheated to 850 °F (454 °C), which became standard for US warships built in the late 1930s and World War II.
