Robert C. Peniston (October 25, 1922 – August 2, 2014) was a career United States Navy officer who rose to the rank of captain and commanded the battleship USS "New Jersey".
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.
USS "New Jersey" (BB-62) ("Big J" or "Black Dragon") is an "Iowa"-class battleship , and was the second ship of the United States Navy to be named after the US state of New Jersey.
 "New Jersey" earned more battle stars for combat actions than the other three completed "Iowa"-class battleships, and was the only US battleship providing gunfire support during the Vietnam War.
The 16"/45 caliber gun (spoken "sixteen-inch-forty-five-caliber") was used for the primary batteries of the last class of Standard-type battleships for the United States Navy, the "Colorado"-class .
 These guns promised twice the muzzle energy over the Mark 7 12-inch/50 caliber guns of the "Wyoming"-class battleship and a 50% increase over the 14-inch/45 caliber guns of the "New York"-class , "Nevada"-class , and "Pennsylvania"-class battleship s.
"Illinois" (BB-65) was an uncompleted battleship originally intended to be the first ship of the "Montana" class .
 However, the U.S. Navy's experiences in World War II led it to conclude that rather than more battleships larger and more heavily armed than the "Iowa" class , it needed more fast battleships of that class to escort the new "Essex"-class aircraft carrier s being built.
 As a result, hull BB-65 was reordered as an "Iowa"-class battleship midway through the war.
USS "Kentucky" (BB-66) was an uncompleted battleship originally intended to be the second ship of the "Montana" class .
 However, the U.S. Navy's experiences in World War II led it to conclude that rather than more battleships larger and more heavily armed than the "Iowa" class , it needed more fast battleships of that class to escort the new "Essex"-class aircraft carrier s being built.
 As a result, hull BB-66 was reordered as an "Iowa"-class battleship midway through the war.
J.R. Perret was the head of Elswick Ordnance Company in the early twentieth century who designed warships such as the Brazilian "Minas Geraes"-class battleship s and "Rio de Janeiro" (later HMS "Agincourt" ), and the Chilean "Almirante Latorre"-class battleship s.
Starting in the 1890s, the Italian "Regia Marina" (Royal Navy) began building a series of modern battleships.
 Early designs were marked by their small size, light armor, and high speed compared to contemporary foreign counterparts.
 The first pre-dreadnought battleship design, the "Ammiraglio di Saint Bon" class , was constrained by budgetary limits imposed by the legislature.
 Two ships were ordered by the class's namesake, Admiral Simone de Pacoret Saint Bon, though the design was also influenced by Benedetto Brin, who replaced di Saint Bon as naval minister after his death.
 Brin designed the next pair of battleships, the "Regina Margherita" class .
 These ships were larger than the preceding class, and were intended to challenge the Austro-Hungarian "Habsburg"-class battleship s then under construction.
 Brin himself died during the construction process.
 Vittorio Cuniberti designed the next class of small pre-dreadnoughts, the "Regina Elena" class , which were the fastest battleships in the world at the time of their completion.
 These ships all served in the Italo-Turkish War of 1911–12, where they were primarily used to provide naval gunfire support for the Italian ground troops, as the Ottoman Navy largely confined itself to port.
USS "Iowa" (BB-61) is the lead ship of her class of battleship and the fourth in the United States Navy to be named after the state of Iowa.
 Owing to the cancellation of the "Montana"-class battleship s, "Iowa" is the last lead ship of any class of United States battleships and was the only ship of her class to have served in the Atlantic Ocean during World War II.
The 38 cm SK C/34 naval gun was developed by Germany mid to late 1930s.
 It armed the "Bismarck"-class battleship s and was planned as the armament of the O-class battlecruiser s and the re-armed "Scharnhorst"-class battleship s. Six twin-gun mountings were also sold to the Soviet Union and it was planned to use them on the "Kronshtadt"-class battlecruiser s, however they were never delivered.
 Spare guns were used as coastal artillery in Denmark, Norway and France.
 One gun is currently on display at Møvig Fortress outside Kristiansand.
