A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several operational roles from search-and-destroy to ocean escort to sea denial.
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.
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 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 USN 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.
The Tiger class were a class of three British warships of the 20th century and the last all-gun cruisers of the Royal Navy. Construction of three Minotaur-class cruisers began during World War II but, due to post-war austerity, the Korean War and focus on the Royal Air Force over the surface fleet, the hulls remained unfinished. Against a background of changing priorities and financial constraints, approval to complete them to a modified design was given in November 1954 and the three ships – Tiger, Lion and Blake – entered service from March 1959.
The Dido class consisted of sixteen light cruisers built for the Royal Navy during World War II. The first group of three ships were commissioned in 1940; the second group of six ships and third group of two were commissioned between 1941 and 1942. A fourth group, also described as the Improved Dido or Bellona class were commissioned between 1943 and 1944. Most members of the class were given names drawn from classical history and legend. The groups differed in armament, and for the Bellonas, in function. The Dido class were designed to replace the C-class and D-class cruisers as small fleet cruisers and flotilla leaders for the destroyer screen. As designed, they mounted five twin 5.25-inch high-angle gun turrets on the centreline providing dual-purpose anti-air and anti-surface capacity; the complex new turrets were unreliable when introduced, and somewhat unsatisfactory at a time when the UK faced a fight for survival. During the war, the original 1939-42 ships required extensive refit work to increase electrical generating capacity for additional wartime systems and in the final Bellona,HMS Diadem, fully-electric turrets. While some damage was experienced initially in extreme North Atlantic weather, changes to gun handling and drill partially mitigated the problems. The fitting of the three forward turrets in the double-superfiring A-B-C arrangement relied upon the heavy use of aluminium in the ships' superstructure, and the lack of aluminium after the evacuation of the British Army from France was one of the primary reasons for the first group only receiving four turrets, while the third group received four twin 4.5-inch mounts and no 5.25-inch guns at all. The Bellonas were designed from the start with four radar-directed 5.25-inch gun turrets with full Remote Power Control and an expanded light anti-aircraft battery, substantially increasing their efficiency as AA platforms.
USS Portsmouth was a Cleveland-class light cruiser of the United States Navy, which were built during World War II. The class was designed as a development of the earlier Brooklyn-class cruisers, the size of which had been limited by the First London Naval Treaty. The start of the war led to the dissolution of the treaty system, but the dramatic need for new vessels precluded a new design, so the Clevelands used the same hull as their predecessors, but were significantly heavier. The Clevelands carried a main battery of twelve 6-inch (152 mm) guns in four three-gun turrets, along with a secondary armament of twelve 5 in (127 mm) dual-purpose guns. They had a top speed of 32.5 knots. Portsmouth was laid down in 1943, launched in September 1944, and commissioned in June 1945. By the time she completed her initial sea trials, the war had ended, so her career was short and uneventful. She made three overseas cruises to visit ports in Africa and the Mediterranean Sea between 1946 and 1948 before conducting training cruises later in 1948. The following year, she was decommissioned and assigned to the Atlantic Reserve Fleet, where she remained until 1970, when she was broken up.
The United States Navy's Boston class were the first guided missile cruisers in the world. Both ships in this experimental class were originally Baltimore-class heavy cruisers that had been decommissioned after World War II, but were redesignated as guided missile heavy cruisers (CAGs) and entered refit in 1952. The lengthy conversion and modernization project involved replacing the aft triple 8-inch gun turret and its supporting structure with two twin launchers for Terrier anti-aircraft guided missiles. The forward two 8-inch gun turrets remained unchanged. The forward superstructure was modified to include the Terrier's associated radars and electronics, the aft superstructure was completely replaced, and the Baltimore class's two funnels were trunked to one.
The Baltimore-class heavy cruisers were a class of heavy cruisers in the United States Navy commissioned during and shortly after World War II. Fourteen Baltimores were completed, more than any other class of heavy cruiser, along with another three ships of the Oregon City sub-class. The Baltimores also were the first cruisers in the US Navy to be designed without the limitations of the London Naval Treaty.
The Atlanta-class cruisers were eight United States Navy light cruisers which were designed as fast scout cruisers, flotilla leaders, or destroyer 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 Brooklyn-class cruiser was a class of nine light cruisers built for the United States Navy between 1935 and 1938. Armed with five triple 6-inch (152 mm) gun turrets, they mounted more main battery guns than any other standard US cruiser. The Brooklyn-class ships were all commissioned between 1937 and 1939, in the time between the start of the Second Sino-Japanese War and before the invasion of Poland. They served extensively in both the Pacific and Atlantic theaters during World War II.
The Oregon City-class was a class of heavy cruisers of the United States Navy. Although ten ships of this class were planned, only four were completed – one of those as a command ship. The three ships completed as cruisers were in commission from 1946 to 1980, one having been converted to a guided missile cruiser (CG).
Originally built as Cleveland-class light cruisers (CL) in the United States Navy during World War II, in 1957 three ships were re-designated as Galveston-class guided missile light cruisers (CLG) and fitted with the Talos long-range surface-to-air missile system. During the two-year refit under project SCB 140, the aft superstructure was completely replaced and all aft guns were removed to make room for the twin-arm Talos launcher and a 46-missile storage magazine. Three large masts were also installed in order to hold a variety of radars, missile guidance, and communications systems. Little Rock and Oklahoma City were simultaneously converted into fleet flagships under SCB 140A, which involved removing two forward dual 5-inch (127 mm) and one triple 6-inch (152 mm) turrets, and replacing them with a massively rebuilt and expanded forward superstructure. Galveston, in the non-flagship configuration, retained the Cleveland-class's standard forward weapons: three dual 5-inch (127 mm) and two triple 6-inch (152 mm) turrets.
Originally built as Cleveland-class light cruisers (CL) in the United States Navy during World War II, in 1957 three ships were re-designated as Providence-class guided missile light cruisers (CLG) and fitted with the Terrier surface-to-air missile system. During the two year refit under project SCB 146, the aft superstructure was completely replaced and all aft guns were removed to make room for the twin-arm Terrier launcher and a 120 missile storage magazine. Three large masts were also installed in order to hold a variety of radars, missile guidance, and communications systems. Providence and Springfield were simultaneously converted into fleet flagships under SCB 146A, which involved removing two forward dual 5-inch (127 mm) and one triple 6-inch (152 mm) turrets, and replacing them with a massively rebuilt and expanded forward superstructure. Topeka, in the non-flagship configuration, retained the Cleveland-class's standard forward weapons: three dual 5-inch (127 mm) and two triple 6-inch (152 mm) turrets.
The Albany-class guided-missile cruisers were converted Baltimore and Oregon City-class heavy cruisers of the United States Navy. All original superstructure and weapons were removed and replaced under project SCB 172. The converted ships had new very high superstructures and relied heavily on aluminium to save weight.
HMS Superb was a Minotaur-class light cruiser of the Royal Navy. The ship entered service in 1945 and had a brief, quiet career before being decommissioned in 1957 after her modernisation was cancelled. She was broken up in 1960.
The Fargo-class cruisers were a modified version of the Cleveland-class cruiser design; the main difference was a more compact pyramidal superstructure with single trunked funnel, intended to improve the arcs of fire of the anti-aircraft (AA) guns. The same type of modification differentiated the Baltimore and Oregon City classes of heavy cruisers, and to a lesser degree the Atlanta and Juneau classes of light cruisers. Changes were made in order to reduce the instability of the Cleveland-class light cruisers, especially their tendency to roll dangerously. The main battery turrets sat about a foot lower and the wing gunhouses were lowered to the main deck. The medium (40 mm) anti-aircraft mounts were also lowered.
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 anti-aircraft 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.
USS Alaska was the lead ship of the Alaska-class "large cruisers" which served with the United States Navy during the end of World War II. She was the first of two ships of her class to be completed, followed only by Guam; four other ships were ordered but were not completed before the end of the war. Alaska was the third vessel of the US Navy to be named after what was then the territory of Alaska, and was assigned the hull number CB-1. She was laid down on 17 December 1941, ten days after the United States entered the war, was launched in August 1943 by the New York Shipbuilding Corporation, in Camden, New Jersey, and was commissioned in June 1944. She was armed with a main battery of nine 12 in (305 mm) guns in three triple turrets and had a top speed of 33 kn.
The Neptune class was a proposed class of cruisers planned for the British Royal Navy in the latter years of the Second World War. They were large ships which were to be armed with twelve 6-inch (152 mm) dual-purpose guns and with a heavy secondary armament. Although five ships of the class were planned in 1944, they were cancelled following the end of the war and before construction could begin.
