The Clemson class was a series of 156 destroyers which served with the United States Navy from after World War I through World War II.
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 Pennsylvania class of six armored cruisers served in the United States Navy from 1905 to 1927. All six were renamed for cities 1912–1920, to make the state names available for the new battleships beginning with the Pennsylvania-class battleships. All of these served during World War I, with California being the only ship of the class to be lost. The remaining five armored cruisers were scrapped between 1930 and 1931 in accordance with the London Naval Treaty.
The second USS Truxtun (DD-14) was the lead ship of Truxtun-class destroyers in the United States Navy. She was named for Commodore Thomas Truxtun.
The first USS Worden (DD-16) was a Truxtun-class destroyer in the United States Navy. She was named for Admiral John Lorimer Worden. It was the first US ship equipped with a stabilizer.
The Bainbridge-class destroyers were a class of United States Navy Torpedo Boat Destroyers (TBDs) built between 1899 and 1903. The first class so designated, they comprised the first 13 of 16 TBDs authorized by Congress in 1898 following the Spanish–American War. One ship of the class was lost at sea during service in World War I: Chauncey, which collided with the British merchant ship SS Rose in 1917. The balance were decommissioned in 1919 and sold postwar in 1920, eleven to Joseph G. Hitner of Philadelphia, and the Hopkins to the Denton Shore Lumber Company in Tampa, Florida.
The Smith-class destroyers were the first ocean-going torpedo-boat destroyers in the United States Navy, and the first to be driven by steam turbines instead of the reciprocating engines fitted in the sixteen earlier and much smaller torpedo-boat destroyers ordered under the Act of 4 May 1898. Flusser and Reid are sometimes considered to be Flusser-class ships. Also, since Flusser was completed first, some period documentation refers to the entire class as Flussers.
The Paulding-class destroyers were a series of United States Navy destroyers derived from the Smith class with the torpedo tubes increased from three to six via twin mounts. They were the first destroyers in the US Navy with oil-fired boilers. The 21 Pauldings doubled the number of destroyers in the US Navy. The Paulding class derived its name from the class's lead ship, Paulding, named for Rear Admiral Hiram Paulding (1797–1878). Like the Smiths, they were nicknamed "flivvers" after the small and shaky Model T Ford once the larger "thousand tonner" destroyers entered service.
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 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.
USS Semmes (DD-189/AG-24) was a Clemson-class destroyer in the United States Navy during World War II. She was the first Navy ship named for Commander (USN), Rear Admiral (CSN), Brigadier General (CSA) Raphael Semmes (1809–1877).
The Hotchkiss gun can refer to different products of the Hotchkiss arms company starting in the late 19th century. It usually refers to the 1.65-inch (42 mm) light mountain gun; there were also a navy (47 mm) and a 3-inch (76 mm) Hotchkiss guns. The 42 mm gun was intended to be mounted on a light carriage or packed on two mules to accompany a troop of cavalry or an army travelling in rough country.
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 St. Louis-class cruisers were a class of three cruisers that served in the United States Navy at the beginning of the 20th century. Authorized in fiscal year 1901 by an Act of Congress of 7 June 1900 as part of the naval buildup touched off by the Spanish–American War, the St. Louis-class cruiser initially began as an improved Olympia. However, during the design phase, decisions were made that increased the size of the vessel from 6,000 long tons (6,100 t) to 9,700 long tons (9,900 t), including adding protection that resulted in the designation "semi-armored cruiser". This led to a larger power plant, and other decisions were made to try to increase speed and range, such as using smaller 6-inch (152 mm) guns instead of 8-inch (203 mm) guns, and adding coal capacity. The completed ship at 9,700 long tons was the same displacement as a full armored cruiser without the same armor. One reference describes the class as "among the earliest well-documented examples of creeping growth in warship design".
The 3.7 cm SK C/30 was the German Kriegsmarine's primary 3.7 cm (1.5 in) anti-aircraft gun during the Second World War. It was superseded by the fully automatic 3.7 cm FlaK 43 late in the war.
The Cannone-Mitragliera da 37/54 (Breda) was a 37 mm (1.5 in) automatic anti-aircraft gun produced by the Breda company in Italy.
The 305 mm /46 Model 1909 was a naval gun that was the main armament of two classes of Italian dreadnought battleships and one unique dreadnought of the Regia Marina built at the beginning of World War I. Many of these guns were later modified to 320 mm Model 1934 and 320 mm Model 1936 naval guns by boring out their barrels, adding new liners and developing new ammunition. A number of unconverted guns including those from the scrapped Dante Alighieri and the salvaged Leonardo da Vinci were also used as coastal artillery during World War II.
The Škoda 30.5 cm /45 and Škoda 30.5 cm /45 K10 were a family of related naval guns of the Austro-Hungarian Empire that were used aboard the last classes of pre-dreadnoughts and dreadnoughts of the Austro-Hungarian Navy during the World War I. Guns salvaged from these ships after World War I were later used by the Royal Italian Army as coastal artillery during World War II.
The Canon de 37 mm Modèle 1925 was a widely used family of French anti-aircraft guns used by the French Navy during World War II.
