USS Brooklyn (ACR-3/CA-3) was the third United States Navy armored cruiser, the only one to be named at commissioning for a city rather than a state.
The first USS Newark (C-1) was a United States Navy protected cruiser, the eighth protected cruiser launched by the United States. In design, she succeeded the "ABC" cruisers Atlanta, Boston, and Chicago with better protection, higher speed, and a uniform 6-inch gun armament. Four additional protected cruisers were launched for the USN prior to Newark.
USS New York (ACR-2/CA-2) was the second United States Navy armored cruiser so designated; the first was the ill-fated Maine, which was soon redesignated a second-class battleship. Due to the unusually protracted construction of Maine, New York was actually the first armored cruiser to enter U.S. Navy service. The fourth Navy ship to be named in honor of the state of New York, she was later renamed Saratoga and then Rochester. With six 8-inch guns, she was the most heavily armed cruiser in the US Navy when commissioned.
The fifth USS Boston was a protected cruiser and one of the first steel warships of the "New Navy" of the 1880s. In some references she is combined with Atlanta as the Atlanta class, in others as the Boston class.
The first USS Chicago was a protected cruiser of the United States Navy, the largest of the original three authorized by Congress for the "New Navy" and one of the U.S. Navy's first four steel ships.
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 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 New Orleans class of protected cruisers of the United States Navy consisted of two ships which were building for the Brazilian Navy at Elswick, near Newcastle Upon Tyne, England, by Armstrong Whitworth. The Brazilian Navy had ordered four Elswick cruisers, but had already sold the first ship during construction to Chile as Ministro Zenteno. One ship was delivered to Brazil, named Almirante Barroso. The third ship was fitting out as Amazonas, and the fourth was on order as Almirante Abreu.
The first USS San Francisco (C-5) was a steel protected cruiser in the United States Navy. She was later named Tahoe and then Yosemite, becoming the third US Navy ship to bear the name Yosemite. She generally resembled her predecessor Newark, with a main armament of twelve 6-inch guns.
The three Chester-class cruisers were the first United States Navy vessels to be designed and designated as fast "scout cruisers" for fleet reconnaissance. They had high speed but little armor or armament. They were authorized in January 1904, ordered in fiscal year 1905, and completed in 1908. In 1920 all scout cruisers were redesignated as "light cruisers" (CL).
The Derfflinger class was a class of three battlecruisers of the Imperial German Navy. The ships were ordered for the 1912–13 Naval Building Program of the German Imperial Navy as a reply to the Royal Navy's two new Lion-class battlecruisers that had been launched a few years earlier. The preceding Moltke class and the incrementally improved Seydlitz represented the end of the evolution of Germany's first generation of battlecruisers. The Derfflinger class had considerable improvements, including a larger primary armament, all of which was mounted on the centerline. The ships were also larger than the preceding classes. The Derfflinger class used a similar propulsion system, and as a result of the increased displacement were slightly slower.
The 6-inch/47-caliber Mark 16 gun was used in the main batteries of several pre-war and World War II US Navy light cruisers. They were primarily mounted in triple turrets and used against surface targets. The Mark 16DP gun was a dual-purpose fitting of the Mark 16 for use against aircraft as well as surface ships. It was installed in the postwar Worcester-class light cruisers and the anti-aircraft gunnery training ship Mississippi.
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 Columbia-class cruisers were two protected cruisers constructed in 1890 and 1891 and used by the United States Navy. They were lightly gunned ships with only moderate armor that were built for the speed needed to overtake and destroy the fast ocean liners of the day as commerce raiders. However, the light armament and armor left these ships over-specialized and outclassed by ordinary similar sized protected cruisers that they might encounter. Also, the engines were expensive to operate and at full power the ships' range was greatly decreased. Due to the ongoing size and speed race in ocean liners, by 1907 they were outclassed in speed by the ill-fated Lusitania and the German liner Kronprinzessin Cecilie.
The Denver-class cruisers were a group of six protected cruisers in service with the United States Navy from 1903 through 1929. Authorized by Congress in 1899 as part of the naval buildup touched off by the Spanish–American War, they were designed with peacetime duties on foreign stations and tropical service in mind, specifically patrolling Latin America and the Caribbean. However, they had insufficient armament, armor, and speed for combat with most other cruisers. Thus, they were also called "peace cruisers" and were effectively gunboats. They were intended to augment the Montgomery class in these roles.
SMS Erzherzog Karl was a pre-dreadnought battleship built by the Austro-Hungarian navy in 1902. The lead ship of the Erzherzog Karl class, she was launched on 3 October 1903. They were assigned to the III Battleship Division.
SMS Erzherzog Ferdinand Max was a pre-dreadnought battleship built by the Austro-Hungarian Navy in 1902. The second ship of the Erzherzog Karl class, she was launched on 21 May 1905. She was assigned to the III Battleship Division.
SMS Erzherzog Friedrich was a pre-dreadnought battleship built by the Austro-Hungarian Navy in 1902. The second ship of the Erzherzog Karl class, she was launched on 30 April 1904. She was assigned to the III Battleship Division.
The Montgomery-class cruisers were three unprotected cruisers built for the United States Navy in the early 1890s. They had a thin water-tight protective deck, and also relied for protection upon their coal bunkers, cellulose packing, and numerous compartments. Roomy accommodations were provided for officers and crew, these cruisers being mainly intended for long cruises on distant stations.
The Neptune class was a proposed class of cruisers planned for the British Royal Navy in the latter years of the Second World War. They were large ships which were to be armed with twelve 6-inch (152 mm) dual-purpose guns and with a heavy secondary armament. Although five ships of the class were planned in 1944, they were cancelled following the end of the war and before construction could begin.
