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.

Ordered for $3,450,420.29 (hull and machinery), she was launched on 2 October 1895 by William Cramp & Sons Ship and Engine Building Company of Philadelphia; sponsored by Miss Ida May Schieren, daughter of Charles A. Schieren, Mayor of Brooklyn, New York; and commissioned on 1 December 1896, Captain Francis Augustus Cook in command.

Design and construction

Brooklyn was said to be an improved at the time of her completion. She was also designed by the Navy Department and was about 1,000 tons larger, which allowed for a raised forecastle for better seakeeping. However, Brooklyn sacrificed armor for improved armament. She had eight 8-inch guns compared to New Yorks six, and all were in twin turrets. The secondary armament was increased in caliber from New Yorks 4-inch guns to 5-inch guns. Brooklyn had her turrets in a "lozenge" arrangement (one each fore and aft, one on each side) and also had a tumblehome hull, which allowed the side turrets to fire dead ahead and astern. She was the only US Navy ship built with this turret arrangement.

Compared with New York, Brooklyn had a belt versus , barbettes versus , and the same turret and deck armor. The forward and starboard side turrets were electric-powered, while the other two turrets were steam-powered. This was to test which system was better, and as a result the Navy adopted electric power for future turret designs.

Armor

Brooklyn had significantly less protection than New York, to allow for increased armament. The belt was thick and deep, of which was below the waterline. It protected only the machinery spaces.

Brooklyn returned to Tompkinsville, New York on 20 August; cruised along the Atlantic coast and in Caribbean waters; participated in the Spanish–American War Victory Celebration at New York on 5 October; and in the Dewey Celebration at New York in September 1899. She left Hampton Roads on 16 October and sailed via the Suez Canal to Manila, Philippine Islands, where she arrived on 16 December. She became flagship of the Asiatic Squadron and participated in the China Relief Expedition (8 July – 11 October 1900. She made a cruise to the Dutch East Indies, Australia and New Zealand from 10 April – 7 August 1901; the last stage was to Melbourne, Auckland, Wellington and Sydney. She remained with the Asiatic Squadron until 1 March 1902, when she sailed for the United States via the Suez Canal and arrived at the New York Navy Yard on 1 May.
