USS New Hampshire (BB-25) was the last of the Connecticut-class pre-dreadnought battleships built for the United States Navy, representing the culmination of early 20th-century battleship design. Constructed by the New York Shipbuilding Corporation in Camden, New Jersey, she was laid down on May 1, 1905, launched on June 30, 1906, and commissioned on March 19, 1908, with Captain Cameron Winslow as her first commander. She measured approximately 456 feet 4 inches in length, with a beam of 76 feet 10 inches and a draft of 24 feet 6 inches. Her displacement was 16,000 long tons designed, increasing to about 17,666 long tons at full load. Powered by two-shaft triple-expansion steam engines fed by twelve coal-fired boilers, she could reach a top speed of 18 knots. Her armament included four 12-inch/45 caliber guns mounted in twin turrets, eight 8-inch/45 guns in four twin turrets amidships, and twelve 7-inch/45 guns in casemates. For close defense, she was equipped with twenty 3-inch guns, twelve 3-pounder guns, and four 37mm guns, along with four 21-inch torpedo tubes submerged in her hull. Armor protection comprised a 9-inch main belt over vital spaces, 12-inch gun turrets, and 10-inch barbettes, with other areas protected by 7- and 9-inch armor. Throughout her active career, USS New Hampshire participated in diplomatic visits, including trips to Europe and the Baltic, and conducted naval operations in the Caribbean during regional unrest, notably during the occupation of Veracruz, where her commander received the Medal of Honor for his actions. During World War I, she served primarily as a training ship and convoy escort, including escorting troop and cargo ships across the Atlantic. Post-war, she returned American soldiers from Europe and engaged in various training cruises and patrols until her decommissioning in 1921. Following the Washington Naval Treaty, she was sold for scrap in 1923, marking the end of her maritime service, but her career highlights the transitional era of battleship design before the advent of dreadnoughts revolutionized naval warfare.
