USS New York (BB-34) was a United States Navy battleship, the lead ship of her class. Named for New York State, she was designed as the first ship to carry the 14-inch (356 mm)/45-caliber gun.
The Tennessee class consisted of two dreadnought battleships—Tennessee and California—built for the United States Navy in the late 1910s, part of the "standard" series. The class was in most respects a repeat of the preceding New Mexico class, with the primary improvements being a significantly strengthened underwater protection system, and increased elevation of the main battery guns to allow them to fire at much greater ranges. They carried the same main battery of twelve 14-inch (356 mm) guns in four triple turrets, and had the same top speed of 21 knots. Both ships served in the Pacific Fleet for the duration of their careers, which included an extensive training program during the interwar period of the 1920s and 1930s.
USS Mississippi (BB-41/AG-128), the second of three members of the New Mexico class of battleship, was the third ship of the United States Navy named in honor of the 20th state. The ship was built at the Newport News Shipbuilding Company of Newport News, Virginia, from her keel laying in April 1915, her launching in January 1917, and her commissioning in December that year. She was armed with a battery of twelve 14-inch (356 mm) guns in four three-gun turrets, and was protected by heavy armor plate, with her main belt armor being 13.5 inches (343 mm) thick.
A heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203 mm (8 inches) in calibre, whose design parameters were dictated by the Washington Naval Treaty of 1922 and the London Naval Treaty of 1930. Heavy cruisers were generally larger, more heavily-armed and more heavily-armoured than light cruisers while being smaller, faster, and more lightly-armed and armoured than battlecruisers and battleships. Heavy cruisers were assigned a variety of roles ranging from commerce raiding to serving as 'cruiser-killers,' i.e. hunting and destroying similarly-sized ships
USS Idaho (BB-42), a New Mexico-class battleship, was the fourth ship of the United States Navy to be named for the 43rd state. She was the third of three ships of her class. Built by the New York Shipbuilding Corporation of Camden, New Jersey, she was launched in June 1917 and commissioned in March 1919. She was armed with a battery of twelve 14-inch (356 mm) guns in four three-gun turrets, and was protected by heavy armor plate, with her main belt armor being 13.5 inches (343 mm) thick.
USS Hawaii (CB-3) was intended to be the third member of the Alaska-class large cruisers. It was the first United States Navy ship to be named after the then-Territory of Hawaii. Because Hawaii's construction was delayed by higher-priority ships like aircraft carriers, her keel was not laid until December 1943, about two years after her sister ship Guam.
The North Carolina class were a pair of fast battleships, North Carolina and Washington, built for the United States Navy in the late 1930s and early 1940s.
The New Mexico class was a class of three super-dreadnought battleships built for the United States Navy in the late 1910s. The class comprised three ships: New Mexico, the lead ship, Mississippi, and Idaho. Part of the standard series, they were in most respects copies of the Pennsylvania-class battleships that immediately preceded them, carrying over the same main battery arrangement of twelve 14-inch (356 mm) guns, but now increased to 50-caliber. They incorporated several other improvements, including a better arrangement of the secondary battery that increased its usability, a clipper bow that improved seakeeping, and an experimental turbo-electric propulsion system adopted on New Mexico. Like the other standard-type battleships, they had a top speed of 21 knots that allowed the fleet to operate as a tactically homogeneous unit.
The Colorado-class battleships were a group of four United States Navy super-dreadnoughts, the last of its pre-Treaty battleships. Designed during World War I, their construction overlapped the end of that conflict and continued in its immediate aftermath. Though all four keels were laid, only three ships entered service: Colorado, Maryland, and West Virginia. Washington was over 75% completed when she was canceled under the terms of the Washington Naval Treaty in 1922. As such, the 16" gun Colorado-class ships were the last and most powerful battleships built by the U.S. Navy until the North Carolina class entered service on the eve of World War II.
The Alaska-class were six large cruisers ordered before World War II for the United States Navy (USN), of which only two were completed and saw service late in the war. The USN designation for the ships of this class was 'large cruiser' (CB), a designation unique to the Alaska-class, and the majority of leading reference works consider them as such. However, various other works have alternately described these ships as battlecruisers despite the US Navy having never classified them as such, and having actively discouraged the use of the term in describing the class. The Alaskas were all named after territories or insular areas of the United States, signifying their intermediate status between larger battleships and smaller heavy and light cruisers.
Haruna (榛名) was a warship of the Imperial Japanese Navy during World War I and World War II. Designed by the British naval engineer George Thurston and named after Mount Haruna, she was the fourth and last battlecruiser of the Kongō class, amongst the most heavily armed ships in any navy when built. Laid down in 1912 at the Kawasaki Shipyards in Kobe, Haruna was formally commissioned in 1915 on the same day as her sister ship, Kirishima. Haruna patrolled off the Chinese coast during World War I. During gunnery drills in 1920, an explosion destroyed one of her guns, damaged the gun turret, and killed seven men.
Hiei (比叡) was a warship of the Imperial Japanese Navy during World War I and World War II. Designed by British naval architect George Thurston, she was the second launched of four Kongō-class battlecruisers, among the most heavily armed ships in any navy when built. Laid down in 1911 at the Yokosuka Naval Arsenal, Hiei was formally commissioned in 1914. She patrolled off the Chinese coast on several occasions during World War I, and helped with rescue efforts following the 1923 Great Kantō earthquake.
The Atlanta-class cruisers were eight United States Navy light cruisers which were designed as fast scout cruisers or flotilla leaders but which proved to be effective anti-aircraft cruisers during World War II. They were also known as the Atlanta-Oakland class. The Atlanta class originally had 16 x 5-inch (127 mm)/38 caliber guns in eight two-gun turrets, arranged with three superfiring turrets forward, three more superfiring aft and two waist mounts, one port and one starboard, giving the first four Atlanta-class cruisers the heaviest anti-aircraft armament of any cruiser of World War II. The last four ships of the class, starting with Oakland, had a slightly revised armament with a reduced main gun battery - the waist turrets being deleted - as they were further optimized for anti-aircraft fire in light of war experience.
The South Dakota class was a group of four fast battleships built by the United States Navy. They were the second class of battleships to be named after the 40th state; the first were designed in the 1920s and canceled under the terms of the Washington Naval Treaty. Four ships comprised the class: South Dakota, Indiana, Massachusetts, and Alabama. They were designed to the same treaty standard displacement limit of 35,000 long tons (35,600 t) as the preceding North Carolina class and had the same main battery of nine 16"/45 caliber Mark 6 guns in three-gun turrets, but were more compact and better protected. The ships can be visually distinguished from the earlier vessels by their single funnel, compared to twin funnels in the North Carolinas.
The 3"/50-caliber gun in United States naval gun terminology indicates the gun fired a projectile 3 inches (76 mm) in diameter, and the barrel was 50 calibers long. Different guns of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1900 through to 1990 on a variety of combatant and transport ship classes.
The QF 3-pounder Hotchkiss or in French use Canon Hotchkiss à tir rapide de 47 mm were a family of long-lived light 47 mm naval guns introduced in 1886 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 32 to 50 calibers but 40 caliber was the most common version. They were widely used by the navies of a number of nations and often used by both sides in a conflict. They were also used ashore as coastal defense guns and later as an anti-aircraft gun, whether on improvised or specialized HA/LA mounts.
5"/51 caliber guns initially served as the secondary battery of United States Navy battleships built from 1907 through the 1920s, also serving on other vessels. United States naval gun terminology indicates the gun fired a projectile 5-inch (127 mm) in diameter, and the barrel was 51 calibers long.
A deck gun is a type of naval artillery mounted on the deck of a submarine. Most submarine deck guns were open, with or without a shield; however, a few larger submarines placed these guns in a turret.
The Juneau-class cruisers were United States Navy light cruisers that were modified version of the Atlanta-class cruiser design. The ships had the same dual-purpose main armament as USS Oakland with a much heavier secondary antiaircraft battery, while the anti-submarine depth charge tracks and torpedo tubes were removed along with a redesigned superstructure to reduce weight and increase stability. Three ships were ordered and built, all completed shortly after World War II, but only Juneau remained active long enough to see action during the Korean War.
The CL-154 class of 5-inch (127 mm) gun light cruisers was a United States Navy project from the last two years of World War II, with antecedents reaching back to 1938 and earlier. The CL-154 class was contemporary to the 6-inch (152 mm) gun Worcester-class light cruisers and the 8-inch (203 mm) gun Des Moines-class cruisers: like them the CL-154 design incorporated the lessons learned of World War II combat. The Navy allocated six hull numbers to the CL-154 class for the planned construction, but unlike the Worcester and Des Moines classes the CL-154 class would be cancelled with no units named or constructed. Had these ships been built, they would have been given the hull classification CLAA on 18 March 1949.
