''New Hampshire'' (BB-25) was the sixth and final pre-dreadnought battleship, the last vessel of that type built for the United States Navy. Like most contemporary battleships, she was armed with an offensive armament that consisted of four large-caliber guns and several medium-caliber 7 and 8-inch (178 and 203 mm) guns. The ship was laid down in May 1905, launched in June 1906, and commissioned in March 1908, a little over a year after the revolutionary all-big-gun rendered ships like ''New Hampshire'' obsolescent. Despite being rapidly surpassed by new American dreadnoughts, ''New Hampshire'' had an active career. She made two trips to Europe in 1910 and 1911, and she sank the old battleship , which had been converted into a target ship. ''New Hampshire'' was particularly active in the Caribbean during this period, as several countries, including Haiti, the Dominican Republic, and Mexico devolved into internal political conflicts. These actions included the United States occupation of Veracruz, during which the ship's commander was awarded the Medal of Honor. After the United States entered World War I in April 1917, the ship was used primarily to train gunners and engine room personnel, as the US Navy had expanded significantly to combat the German U-boat campaign. She escorted convoys in late 1918, and after the war ended she took part in the effort to bring American soldiers back from France. ''New Hampshire'' remained in service for only a few years after the war, as the 1922 Washington Naval Treaty significantly reduced the navies of the signatories; as a result, the ship was sold for scrap in November 1923. ==Design== (詳細はlong overall and had a beam of and a draft of . She displaced as designed and up to at full load. The ship was powered by two-shaft triple-expansion steam engines rated at and twelve coal-fired Babcock & Wilcox boilers, generating a top speed of . As built, she was fitted with heavy military masts, but these were quickly replaced by lattice masts in 1909. She had a crew of 827 officers and men, though this increased to 881 and later to 896. The ship was armed with a main battery of four 12 inch /45 Mark 5 guns in two twin gun turrets on the centerline, one forward and aft. The secondary battery consisted of eight /45 guns and twelve /45 guns. The 8-inch guns were mounted in four twin turrets amidships and the 7-inch guns were placed in casemates in the hull. For close-range defense against torpedo boats, she carried twenty 3-inch /50 guns mounted in casemates along the side of the hull and twelve 3-pounder guns. She also carried four 1-pounder guns. As was standard for capital ships of the period, ''New Hampshire'' carried four torpedo tubes, submerged in her hull on the broadside. ''New Hampshire''s main armored belt was thick over the magazines and the machinery spaces and elsewhere. The main battery gun turrets had thick faces, and the supporting barbettes had the of armor plating. The secondary turrets had 7 in of frontal armor. The conning tower had thick sides. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「USS New Hampshire (BB-25)」の詳細全文を読む スポンサード リンク
