Under Siege is a 1992 American action-thriller film directed by Andrew Davis and written by J.F. Lawton.
 It stars Steven Seagal as an ex-Navy SEAL who must stop a group of mercenaries, led by Tommy Lee Jones and Gary Busey, on the U.S. Navy battleship USS "Missouri".
 It is Seagal's most successful film in critical and financial terms, including two Academy Award nominations for sound production.
 The musical score was composed by Gary Chang.
 It was followed by a 1995 sequel, "".
USS "Iowa" (BB-4) was a United States Navy battleship.
 It was the first ship commissioned in honor of Iowa and was America's first seagoing battleship.
 "Iowa" saw substantial action in the Spanish–American War.
 While she was an improvement over the "Indiana" class because of a superior design, the warship became obsolete quickly in the first quarter of the 20th century and was used for target practice and sunk on 23 March 1923 in Panama Bay by a salvo of 14-inch shells.
USS "Blue Ridge" (LCC-19) is the lead ship of the two "Blue Ridge"–class command ships of the United States Navy, and is the command ship of the United States Seventh Fleet.
 Her primary role is to provide command, control, communications, computers, and intelligence (C4I) support to the commander and staff of the United States Seventh Fleet.
 She is currently forward-deployed to U.S. Navy Fleet Activities, Yokosuka in Japan, and is the third Navy ship named after the Blue Ridge Mountains, a range of mountains in the Appalachian Mountains of the eastern United States.
 "Blue Ridge" is the oldest deployable warship of the U.S. Navy, following the decommissioning of  in Pearl Harbor on 14 August 2014.
 "Blue Ridge", now the U.S. Navy's active commissioned ship having the longest total period as active, flies the First Navy Jack.
 "Blue Ridge" is expected to remain in service until 2039.
USS "Missouri" (BB-63) ("Mighty Mo" or "Big Mo") is a United States Navy "Iowa"-class battleship and was the third ship of the U.S. Navy to be named after the U.S. state of Missouri.
 "Missouri" was the last battleship commissioned by the United States and is best remembered as the site of the surrender of the Empire of Japan which ended World War II.
USS "Texas" was a second-class battleship built by the United States in the early 1890s, the first American battleship commissioned and the first ship named in honor of the state of Texas to be built by the United States.
 Built in reaction to the acquisition of modern armored warships by several South American countries, "Texas" was meant to incorporate the latest developments in naval tactics and design.
 This includes the mounting of her main armament "en echelon" to allow maximum end-on fire and a heavily-armored redoubt amidships to ensure defensive strength.
 However, due to the state of U.S. industry at the time, "Texas's" building time was lengthy, and by the time she was commissioned, she was already out of date.
 Nevertheless, she and her near-sister USS "Maine" were considered advancements in American naval design.
The first "South Dakota" class was a class of six American battleships that were laid down in 1920 but never completed.
 They would have been the last dreadnoughts in the Naval Act of 1916 to be commissioned had the Washington Naval Treaty not caused their cancellation one-third of the way through their construction.
 They would have been the largest, most heavily armed and armored battleships in the U.S. Navy and, designed to achieve 23 kn , represented an attempt to abandon its 21 kn standardized fleet speed and catch up with the increasing fleet speeds of its main rivals, the British Royal Navy and Imperial Japanese Navy.
 In this, size and secondary armament, they represented a break from the Standard-type battleship that had dominated American capital ship design for the prior five ship classes, while their use of standardized bridges, lattice masts and other features was a continuation of this practice and the increase in the number of main guns from the preceding "Colorado" class had long been standard U.S. naval policy.
 The main restriction to which they had to adhere was the ability to pass through the Panama Canal.
The USS "Iowa" turret explosion occurred in the Number Two 16-inch gun turret of the United States Navy battleship  on 19 April 1989.
 The explosion in the center gun room killed 47 of the turret's crewmen and severely damaged the gun turret itself.
 Two major investigations were undertaken into the cause of the explosion, one by the U.S. Navy and then one by the General Accounting Office (GAO) and Sandia National Laboratories.
 The investigations produced conflicting conclusions.
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 Battleship New Jersey Museum and Memorial is located at 62 Battleship Place, Camden, New Jersey, United States.
 This museum ship preserves and displays the  , the most decorated battleship to have served in the U.S. Navy and one of the largest ever built.
USS "Recruit, also known as the Landship "Recruit, was a wooden mockup of a dreadnought battleship constructed by the United States Navy in Manhattan in New York City, as a recruiting tool and training ship during the First World War.
 Commissioned as if it were a normal vessel of the U.S. Navy and manned by a crew of trainee sailors, "Recruit" was located in Union Square from 1917 until the end of the war.
 In 1920, with the reduced requirements for manning in the post-war Navy, "Recruit" was decommissioned, dismantled, and moved to Coney Island. "
The New York Times" reported at the time that the "Landship" had helped the U.S. Navy recruit 25,000 men into the service—625 times the size of her own crew, and enough to crew twenty-eight "Nevada"-class battleships.
