USNS "Mission San Francisco" (T-AO-123) was a "Mission Buenaventura"-class oiler that served in the United States Navy.
 The ship was originally intended as USS "Contoocook" (AO-104) for the U.S. Navy but her acquisition was canceled.
 The ship, a Type T2-SE-A3 tanker, was completed as SS "Mission San Francisco" and delivered after the end of World War II.
 The tanker was acquired by the U.S. Navy in 1947 as USS "Mission San Francisco" (AO-123), but was transferred to the Military Sea Transport Service (MSTS) upon its creation in 1949.
 During a second stint with the MSTS that began in 1954, "Mission San Francisco" collided with the freighter "Elna II" in the Delaware River coast and was declared unsalvageable by the U.S. Navy.
 The ship was one of two U.S. Navy vessels named for the Franciscan mission of San Francisco de Asís located in San Francisco, California.
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.

The two "Nevada"-class battleship s were the first Standard-type battleships produced by the U.S. Navy, and also the first to use triple main turrets.
 "Nevada" (BB-36) and "Oklahoma" (BB-37) were both ordered in March 1911.
 In armament, armor, and propulsion the "Nevada" class represented a considerable evolution in battleship design and, in being designed specifically to fight at extreme gunnery ranges, was actually well ahead of its time.
 They would be followed by the "Pennsylvania"-class battleship s.
Kenneth Whiting (22 July 1881 – 24 April 1943) was a United States Navy officer who was a pioneer in submarines and is best known for his lengthy career as a pioneering naval aviator.
 During World War I, he commanded the first American military force to arrive in Europe for combat.
 After the war, he was instrumental in development of the aircraft carrier in the United States, where he sometimes is known as the U.S. Navy' s "father of the aircraft carrier."
 He was involved in some way in the design or construction of five of the first six U.S. Navy aircraft carriers, and served as acting commanding officer of the first carrier to enter U.S. Navy service and as executive officer of the first two American carriers.
 In the earliest days of the U.S. Navy' s development of an aircraft carrier force, he led many shipboard innovations still in use aboard carriers today.
USS "North Carolina" (BB-55) was the lead ship of "North Carolina"-class battleship s and the fourth warship in the U.S. Navy to be named for the State of North Carolina.
 She was the first newly constructed American battleship to enter service during World War II, and took part in every major naval offensive in the Pacific Theater of Operations; her 15 battle stars made her the most decorated American battleship of World War II.
 She is now a museum ship and memorial kept at the seaport of Wilmington, North Carolina.
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.
The Battleship New Jersey Museum and Memorial is located at 62 Battleship Place, Camden, New Jersey, United States.
