The United States Navy began building a series of battlecruisers in the 1920s, more than a decade after their slower and less heavily armed armored cruisers had been rendered obsolete by the Royal Navy's Invincible-class battlecruisers. Construction of these ships was abandoned under the terms of an armaments limitation treaty, though two were completed as aircraft carriers. The US Navy subsequently ordered six "large cruisers"—which are often considered battlecruisers by historians—in 1940, of which only two entered service.

At first unconvinced of the importance of the superior speed of the British battlecruisers, the US Navy changed its position after evaluating the new type of ship in fleet exercises and Naval War College wargames, and after the Japanese acquisition of four Kongō-class battlecruisers in the early 1910s. The Secretary of the Navy initially refused the General Board's suggested procurement of several battlecruisers, [1] but fleet exercises revealed that the Navy lacked forces that could effectively find and track an enemy fleet in any weather, and a consensus gradually emerged that battlecruisers would be ideal for this role. Battlecruisers were effective when concentrating their fire on an enemy fleet's leading ships, as the Japanese armored cruisers had done to the Russians at the Battle of Tsushima in 1905. Another role envisioned was tracking down and destroying enemy commerce raiders. British experience during the Battle of the Falkland Islands in late 1914 and the Battle of Dogger Bank the following year, where British battlecruisers caught and destroyed German armored cruisers, confirmed all these capabilities.

When Congress authorized a large naval building program in 1916, six Lexington-class battlecruisers were included. None were completed before the arms-limiting Washington Naval Treaty was ratified in 1922; four were broken up on the slipway and two were converted into the aircraft carriers Lexington (CV-2) and Saratoga (CV-3). [2] The treaty forestalled any further development of battlecruisers for the next decade and a half, but a number of countries experimented with "cruiser-killer" ships in the late 1930s that were designed to destroy the post-London Naval Treaty heavy cruisers. These designs were formally designated as battlecruisers by the Dutch and Soviets and as large cruisers by the Japanese and Americans, but all were roughly equivalent and all were commonly called battlecruisers. The US Navy's main impetus for the Alaska class was the threat posed by Japanese cruisers raiding its lines of communication in the event of war. Heavy cruisers were also the most likely surface threat to aircraft carriers making independent raids, so a cruiser-killer was also an ideal carrier escort. [3] Reports of a Japanese equivalent [note 1] reinforced the Navy's desire for these ships. Two were commissioned in time to serve during the last year of World War II, but were decommissioned two years after the war. [5] [6]

The design of the Lexington-class battlecruisers was approved on 30 June 1916 and six were planned as part of the massive 1916 building program, but their construction was repeatedly postponed in favor of escort ships and anti-submarine vessels. [7] The original design mounted ten 14-inch (356 mm) and sixteen 5-inch (127 mm) guns on a lightly armored hull with a maximum speed of 35 knots (65 km/h; 40 mph). The General Board regarded the design's firepower as inadequate and took the opportunity offered by the postponement to order a redesign to improve the ships' armament to include eight 16-inch (406 mm) and sixteen 6-inch (152 mm) guns. After the Americans entered World War I in April 1917, the Royal Navy furnished more information from its analyses of the Battle of Jutland, in which three British battlecruisers were destroyed by magazine explosions, and provided detailed information on the heavily armored design of the Admiral-class battlecruisers then under construction. The General Board then re-evaluated the design and greatly increased the armor protection, at the cost of reducing the maximum speed to 33 knots (61 km/h; 38 mph). Anti-torpedo bulges, additional torpedo bulkheads and a general increase in armor thicknesses increased the design's beam by 11 feet (3.4 m) and increased its displacement by over 7,000 long tons (7,100 t). [8]

While four of the ships were eventually cancelled and scrapped on their slipways to comply with the terms of the Washington Naval Treaty, [9] Lexington and Saratoga, the two most advanced ships, were converted into the United States' first fleet carriers. In World War II, Lexington conducted several raids on Japanese bases before being sunk during the Battle of Coral Sea in May 1942. [10] Saratoga sank the Japanese aircraft carrier Ryūjō during the Battle of the Eastern Solomons three months later, then supported a number of American operations in the Pacific before being attached to the British Eastern Fleet for operations in the Indian Ocean. Though she was torpedoed twice, Saratoga survived the war, and was destroyed as a target ship during Operation Crossroads, a series of atomic bomb tests at Bikini Atoll in mid-1946. [11]

The Alaska-class cruisers were six very large cruisers ordered on 9 September 1940. [17] They were known, popularly and by some historians, as "battlecruisers", [18] [19] although the Navy and at least one prominent historian [17] discouraged describing them as such and gave them the hull symbol for large cruisers (CB). All were named after territories or insular areas of the United States, unlike battleships, generally named for states, or cruisers, named for cities. [note 2] Initial design work for a "cruiser-killer" began in 1938, although the design was not finalized until June 1941. Of the six ships ordered in September 1940, [20] only three were laid down; two of these were completed, [21] and the third's construction was suspended on 16 April 1947 when she was 84% complete. [22]

Alaska and Guam served for the last year of World War II as bombardment ships and fast carrier escorts. Once the two ships reached Bayonne, New Jersey in late 1945 and early 1946, they never left port again. [23] [24] Numerous plans to convert Hawaii into a guided-missile cruiser or a large command ship in the years after the war were fruitless, and she was sold for scrap in 1959, two years before her sisters.

<span class="mw-page-title-main">Battlecruiser</span> Large capital warship, typically faster than battleships

The battlecruiser was a type of capital ship of the first half of the 20th century. These were similar in displacement, armament and cost to battleships, but differed in form and balance of attributes. Battlecruisers typically had thinner armour and a somewhat lighter main gun battery than contemporary battleships, installed on a longer hull with much higher engine power in order to attain greater speeds. The first battlecruisers were designed in the United Kingdom, as a development of the armoured cruiser, at the same time as the dreadnought succeeded the pre-dreadnought battleship. The goal of the design was to outrun any ship with similar armament, and chase down any ship with lesser armament; they were intended to hunt down slower, older armoured cruisers and destroy them with heavy gunfire while avoiding combat with the more powerful but slower battleships. However, as more and more battlecruisers were built, they were increasingly used alongside the better-protected battleships.

<i>Montana</i>-class battleship Proposed class of American super battleships

The Montana-class battleships were planned as successors of the Iowa class for the United States Navy, to be slower but larger, better armored, and with superior firepower. Five were approved for construction during World War II, but changes in wartime building priorities resulted in their cancellation in favor of continuing production of Essex-class aircraft carriers and Iowa-class battleships before any Montana-class keels were laid.

USS <i>Illinois</i> (BB-65) Iowa-class fast battleship

USS Illinois (BB-65) was the fifth Iowa-class fast battleship that was laid down for the United States Navy during World War II in the 1940s, although she would not be completed. The Navy had initially planned on building four of the Iowas and then developing a new, more powerful ship for what was to be BB-65. The pressing need for more warships at the outbreak of World War II in Europe led the Navy to conclude that new designs would have to be placed on hold to allow the shipbuilding industry to standardize on a small number of designs. As a result, BB-65 was ordered to the Iowa design in 1940. Illinois was laid down in December 1942, but work was given a low priority, and was still under construction at the end of World War II. She was canceled in August 1945, but her hull remained as a parts hulk until she was broken up in 1958.

USS <i>Hawaii</i> (CB-3) Never-completed third member of the US Navy Alaska-class large cruisers

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.

<i>Iowa</i>-class battleship Fast battleship class of the United States Navy

The Iowa class was a class of six fast battleships ordered by the United States Navy in 1939 and 1940. They were initially intended to intercept fast capital ships such as the Japanese Kongō class while also being capable of serving in a traditional battle line alongside slower battleships and act as its "fast wing". The Iowa class was designed to meet the Second London Naval Treaty's "escalator clause" limit of 45,000-long-ton (45,700 t) standard displacement. Beginning in August 1942, four vessels, Iowa, New Jersey, Missouri, and Wisconsin, were completed; two more, Illinois and Kentucky, were laid down but canceled in 1945 and 1958, respectively, before completion, and both hulls were scrapped in 1958–1959.

<i>Alaska</i>-class cruiser Class of cruiser ships

The Alaska class were six very large cruisers ordered before World War II for the United States Navy, of which only two were completed and saw service late in the war. The US Navy designation for the ships of this class was 'large cruiser' (CB) 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. 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.

<i>Yamato</i>-class battleship Class of Japanese battleship

The Yamato-class battleships were two battleships of the Imperial Japanese Navy (IJN), Yamato and Musashi, laid down leading up to World War II and completed as designed. A third hull laid down in 1940 was converted to an aircraft carrier, Shinano, during construction.

Design A-150 battleship Planned Imperial Japanese class of super battleships

Design A-150, popularly known as the Super Yamato class, was a planned class of battleships for the Imperial Japanese Navy. In keeping with longstanding Japanese naval strategy, the A-150s would have carried six 51-centimeter (20.1 in) guns to ensure their qualitative superiority over any other battleship they might face. These would have been the largest guns ever carried aboard a capital ship.

Design B-65 cruiser

Design B-65 was a class of Super Type A cruisers planned by the Imperial Japanese Navy (IJN) before and during World War II. As envisioned by the IJN, the cruisers were to play a key role in the Night Battle Force portion of the "Decisive battle" strategy which Japan hoped, in the event of war, to employ against the United States Navy.

O-class battlecruiser Proposed battlecruiser class of the German Navy

The O class was a planned class of three battlecruisers for the Kriegsmarine before World War II. Prompted by a perceived lack in ship numbers when compared with the British Royal Navy, the O class' design was born with the suggestion of modifying the P-class cruiser design with 380 mm (15 in) guns instead of 283 mm (11.1 in).

The Number 13-class battleship was a planned class of four fast battleships to be built for the Imperial Japanese Navy (IJN) during the 1920s. The ships never received any names, being known only as Numbers 13–16. They were intended to reinforce Japan's "eight-eight fleet" of eight battleships and eight battlecruisers after the United States announced a major naval construction program in 1919. The Number 13 class was designed to be superior to all other existing battleships, planned or building. After the signing of the Washington Naval Treaty in 1922, they were cancelled in November 1923 before construction could begin.

<i>Lexington</i>-class battlecruiser US class of battlecruiser

The Lexington-class battlecruisers were officially the only class of battlecruiser to ever be ordered by the United States Navy. While these six vessels were requested in 1911 as a reaction to the building by Japan of the Kongō class, the potential use for them in the U.S. Navy came from a series of studies by the Naval War College which stretched over several years and predated the existence of the first battlecruiser, HMS Invincible. The fact they were not approved by Congress at the time of their initial request was due to political, not military considerations.

Japanese battleship <i>Tosa</i> Planned battleship of the Imperial Japanese Navy

Tosa (土佐) was a planned battleship of the Imperial Japanese Navy. Designed by Yuzuru Hiraga, she was envisioned as the lead ship of the Tosa class of two 39,900-long-ton (40,540 t) ships. The battleships would have been armed with ten 410 mm (16.1 in) guns and brought Japan closer to its goal of an "Eight-four" fleet. All work on the ship was halted after the Washington Naval Conference and the signing of the Washington Naval Treaty. As the vessel had to be destroyed in accordance with the terms of the treaty, the incomplete Tosa was then subjected to tests to gauge the effect of Japanese weaponry before being scuttled on 9 February 1925.

USS <i>Guam</i> (CB-2) US Navy Alaska-class large cruiser

USS Guam was an Alaska-class large cruiser which served with the United States Navy during the last year of World War II. She was the second and last ship of her class to be completed. The ship was the second vessel of the US Navy to be named after the island of Guam, an American territory in the Pacific, and she was assigned the hull number CB-2. Due to her commissioning late in the war, Guam saw relatively limited service during the war. She participated in operations off Okinawa in March–July 1945, including providing anti-aircraft defense for the carrier task force and conducting limited shore bombardment operations. She participated in sweeps for Japanese shipping in the East China and Yellow Seas in July–August 1945. After the end of the war, she assisted in the occupation of Korea and transported a contingent of US Army troops back to the United States. She was decommissioned in February 1947 and placed in reserve, where she remained until she was stricken in 1960 and sold for scrapping the following year.

USS <i>Alaska</i> (CB-1) Lead ship of the US Navy Alaska class of large cruisers

USS Alaska was the lead ship of the Alaska class of 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.
