"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.
