:Alaska-class cruiser

Heavy cruiser development formalized between World War I and World War II due to the terms of the Washington Naval Treaty and successor treaties and conferences, where the United States, Britain, Japan, France, and Italy agreed to limit heavy cruisers to 10,000 tons displacement with 8-inch main armament. Up until the Alaska class, US cruisers designed between the wars followed this pattern.Bauer and Roberts, 139.

The initial impetus for the Alaska design came from the deployments of Germany's so-called pocket battleships in the early 1930s.{{Cite web|last=Knupp|first=Chris|date=17 April 2017|title=The Awesome Alaska Class: America's (Not Quite) Battlecruisers|url=https://www.navygeneralboard.com/the-alaska-class-americas-not-quite-battlecruisers/|access-date=20 July 2021|website=Navy General Board|archive-date=20 July 2021|archive-url=https://web.archive.org/web/20210720213158/https://www.navygeneralboard.com/the-alaska-class-americas-not-quite-battlecruisers/|url-status=live}} Though no actions were immediately taken, these thoughts were revived in the late 1930s when intelligence reports indicated Japan was planning or building "super cruisers" of the B-65 class that would be much more powerful than the current US heavy cruisers.{{cite DANFS | title = Hawaii | url = http://hazegray.org/danfs/cruisers/cb3.txt | access-date=14 October 2008|short=yes|link=no| archive-url= https://web.archive.org/web/20080928005847/http://www.hazegray.org/danfs/cruisers/cb3.txt| archive-date= 28 September 2008 | url-status= live}}Scarpaci, 17.{{efn-ua|Japan actually developed plans for two super cruisers in 1941, though it was mostly in response to the new Alaska ships. However, the ships were not ordered due to the greater need for carriers. See Design B-65 cruiser.}} The navy responded in 1938 when the General Board asked the Bureau of Construction and Repair to conduct a "comprehensive study of all types of naval vessels for consideration for a new and expanded building program".Dulin and Garzke, 189. The US president at the time, Franklin Delano Roosevelt, may have taken a lead role in the development of the class with his desire to have a counter to raiding abilities of Japanese cruisers and German pocket battleships.Dulin and Garzke, 24 and 179. While these claims are difficult to verify,Morison and Polmar, 85. others have speculated that their design was "politically motivated"Dulin and Garzke 267. rather than strategic.

One historian described the design process of the Alaska class as "torturous" due to the numerous changes and modifications made to the ship's layouts by numerous departments and individuals. Indeed, there were at least nine different layouts,Dulin and Garzke, 179–183. ranging from 6,000-ton {{sclass|Atlanta|cruiser|0}} anti-aircraft cruisers to "overgrown" heavy cruisers and a 38,000-ton mini-battleship that would have been armed with twelve 12-inch and sixteen 5-inch guns.Dulin and Garzke, 179. The General Board, in an attempt to keep the displacement under 25,000 tons, allowed the designs to offer only limited underwater protection such that they were vulnerable, by comparison with a battleship, to torpedoes and to shells that fell short of the ship.Dulin and Garzke, 183. The final design was a scaled-up {{sclass|Baltimore|cruiser|4}} that had the same machinery as the {{sclass|Essex|aircraft carrier}}s. This ship combined a main armament of nine 12-inch guns with protection against 10-inch gunfire into a hull that was capable of {{convert|33|kn}}.

The Alaskas were officially funded in September 1940 along with a plethora of other ships as a part of the Two-Ocean Navy Act.Rohwer, 40.{{efn-ua|Over two hundred other ships were ordered at the same time: two {{sclass|Iowa|battleship}}s, five {{sclass|Montana|battleship|2}}s, twelve {{sclass|Essex|aircraft carrier}}s, four {{sclass|Baltimore|heavy cruiser}}s, 19 {{sclass|Cleveland|light cruiser}}s, four {{sclass|Atlanta|light cruiser|2}}s, 52 {{sclass|Fletcher|destroyer}}s, twelve {{sclass|Benson|destroyer|2}}s and 73 {{sclass|Gato|submarine}}s.}} Their role had been altered slightly: in addition to their surface-to-surface role, they were planned to protect carrier groups. This carrier escort capability was favored by Admiral King. Because of their bigger guns, greater size and increased speed, they would be more valuable in this role than heavy cruisers, and would provide insurance against reports that Japan was building super cruisers more powerful than the American heavy cruisers. The escort concept would also free the few existing heavy cruisers for scouting (their original purpose).

Yet another drastic change was considered during the "carrier panic" in late 1941, when the US Navy realized that they needed more aircraft carriers as quickly as possible. Many hulls currently under construction were considered for conversion into carriers. At different times, they considered some or all of the {{sclass|Cleveland|cruiser|0}} light cruisers, the {{sclass|Baltimore|cruiser|0}} heavy cruisers, the Alaska class, and even one of the {{sclass|Iowa|battleship|3}}s; in the end, they chose the Clevelands,Friedman, 190. resulting in the conversion of nine ships under construction at the New York Shipbuilding Corporation shipyard as the light aircraft carriers comprising the {{sclass|Independence|aircraft carrier|0}}.

A conversion of the Alaska cruisers to carriers was "particularly attractive" because of the many similarities between the design of the {{sclass|Essex|aircraft carrier|2}}s and the Alaska class, including the same machinery.Fitzsimons, Volume 1, 58. However, when Alaska cruisers were compared to the Essex carriers, converted cruisers would have had a shorter flight deck (so they could carry only 90% of the aircraft), would have been {{convert|11|ft|m}} lower in the water, and could travel {{convert|8000|nmi|km}} less at {{convert|15|kn}}. In addition, the large cruiser design did not include the extensive underwater protections found in normal carriers due to the armor weight devoted to counter shell fire.{{Clarify|What does this bulky sentence mean to convey? Its meaning is unclear as written.|date=April 2021}} Lastly, an Alaska conversion could not satisfy the navy's goal of having new aircraft carriers quickly, as the work needed to modify the ships into carriers would entail long delays. With this in mind, all planning to convert the Alaskas was abandoned on 7 January 1942.Friedman, 191.

Of the six Alaska-class cruisers that were planned, only three were laid down. The first two, {{USS|Alaska|CB-1|2}} and {{USS|Guam|CB-2|2}}, were completed by the New York Shipbuilding Corporation. Construction of {{USS|Hawaii|CB-3|2}}, the third, was suspended on 16 April 1947 when she was 84% complete. The last three, Philippines, Puerto Rico, and Samoa, were delayed since all available materials and slipways were allocated to higher priority ships, such as aircraft carriers, destroyers, and submarines. Construction had still not begun when steel shortagesFitzsimons, Volume 1, 59. and a realization that these "cruiser-killers" had no more cruisers to hunt—as the fleets of Japanese cruisers had already been defeated by aircraft and submarines—made the ships "white elephants". As a result, construction of the last three members of the class never began, and they were officially cancelled on 24 June 1943.{{cite DANFS | title = Philippines | url = http://hazegray.org/danfs/cruisers/cb4.htm | access-date=15 October 2008|short=yes|link=no| archive-url= https://web.archive.org/web/20081023071417/http://www.hazegray.org/danfs/cruisers/cb4.htm| archive-date= 23 October 2008 | url-status= live}}{{cite DANFS | title = Puerto Rico | url = http://hazegray.org/danfs/cruisers/cb5.htm | access-date=15 October 2008|short=yes|link=no| archive-url= https://web.archive.org/web/20081023071422/http://www.hazegray.org/danfs/cruisers/cb5.htm| archive-date= 23 October 2008 | url-status= live}}{{cite DANFS | title = Samoa | url = http://hazegray.org/danfs/cruisers/cb6.htm | access-date=15 October 2008|short=yes|link=no| archive-url= https://web.archive.org/web/20081020163118/http://www.hazegray.org/danfs/cruisers/cb6.htm| archive-date= 20 October 2008 | url-status= live}}

Both Alaska and Guam protected {{USS|Franklin|CV-13|2}} when she was on her way to be repaired in Guam after being hit by two Japanese bombs. Afterward, Alaska supported the landings on Okinawa, while Guam went to San Pedro Bay to become the leader of a new task force, Cruiser Task Force 95, under the overall command of Vice Admiral Jesse B. Oldendorf. Guam, joined by Alaska, four light cruisers, and nine destroyers, led the task force into the East China and Yellow Seas to conduct raids upon shipping; however, they encountered only Chinese junks.

After the war, both ships served as part of Task Force 71, the designation for the U.S. Seventh Fleet's North China Naval Force.

In 1958, the Bureau of Ships prepared two feasibility studies to explore whether Alaska and Guam could be suitably converted into guided-missile cruisers. The first study involved removing all of the guns in favor of four different missile systems. At $160 million, the cost of this proposed removal was seen as prohibitive, so a second study was initiated. The study left the forward batteries (the two 12-inch triple turrets and three of the 5-inch dual turrets) unchanged, and added a reduced version of the first plan on the stern of the ship. Even though the proposals would have cost approximately half as much as the first study's plan ($82 million), it was still seen as too expensive.Dulin and Garzke 187. As a result, both ships were stricken from the Naval Vessel Register on 1 June 1960. Alaska was sold for scrap on 30 June 1960, and Guam on 24 May 1961.

The still-incomplete {{USS|Hawaii|CB-3|2}} was considered for a conversion to be the Navy's first guided-missile cruiser;{{efn-ua|A similar proposal was made to convert the uncompleted Iowa-class battleship {{USS|Kentucky|BB-66|6}} into the first guided-missile battleship, but as with the proposal for Hawaii this conversion never materialized, and Kentucky was scrapped in 1958.}} this thought lasted until 26 February 1952, when a different conversion to a "large command ship" was contemplated. In anticipation of the conversion, her classification was changed to CBC-1. This would have made her a "larger sister" to {{USS|Northampton|CLC-1|2}}, but a year and a half later (9 October 1954) she was re-designated CB-3. Hawaii was stricken from the Naval Vessel Register on 9 June 1958 and was sold for scrap in 1959.

The Alaska class, along with the Dutch Design 1047 battlecruiser and the Japanese Design B-65 cruiser, were specifically to counter the heavy cruisers being built by their naval rivals. All three have been described as "super cruisers", "large cruisers" or even "unrestricted cruisers", with some (up to Jane's Fighting Ships of World War II itself) advocating that they even be considered as battlecruisers. However, they were never officially classified as capital ships, as that designation was reserved for true battlecruisers and battleships.Chesneau, p. 388; Garzke & Dulin, p. 86; Friedman 1984, p. 288; McLaughlin 2006, p. 104 Early in its development, the class used the US battlecruiser designation CC, which had been planned for the {{sclass|Lexington|battlecruiser|4}}. However, the designation was changed to CB to reflect their new status, "large cruiser", and the practice of referring to them as battlecruisers was officially discouraged. The U.S. Navy then named the individual vessels after U.S. territories, rather than states (as was the tradition with battleships) or cities (for which cruisers were traditionally named), to symbolize the belief that these ships were supposed to play an intermediate role between heavy cruisers and fully-fledged battleships.

The Alaska class certainly resembled contemporary US battleships (particularly the {{sclass|North Carolina|battleship|4}}, {{sclass|South Dakota|battleship (1939)|4}}, and {{sclass|Iowa|battleship|4}}) in appearance, including the familiar 2-A-1 main battery and massive columnar mast. Their displacement was twice that of the newest heavy cruisers (the {{sclass|Baltimore|cruiser|4}}),Morison, Morison and Polmar, 84. being only 5,000 tons less than the Washington Treaty's battleship standard displacement limit of 35,000 long tons (36,000 t) (unchanged through the final naval treaty, the London Treaty of 1936). They were also longer than several treaty battleships such as the {{convert|745|ft|1|in|m|1|abbr=on}} {{sclass|King George V|battleship (1939)|4}} and {{convert|724|ft|abbr=on}} North Carolina class.

In overall terms, the design of the Alaska class was scaled up from that of the {{sclass|Baltimore|cruiser|4}} (themselves the first cruisers in the US Navy to be designed without the limitations of the London Naval Treaty, and exceeding 10,000 tons standard displacement). The armor scheme of the Alaskas was deemed sufficient to provide protection against not only 8″ heavy cruiser shells but even the larger 11″ shells used by Germany's {{sclass|Deutschland|cruiser|0}} "pocket battleships" and {{sclass|Scharnhorst|battleship|5}}-class battleships. However, they lacked the comprehensive underwater protection systems found on the larger US battleships or even on smaller, earlier battleships like the French {{sclass|Dunkerque|battleship|5}} and German Scharnhorst classes. Thus, the Alaskas were potentially as vulnerable to torpedoes as a heavy cruiser was, as well as to effects from near-misses and 'shorts' (where enemy gunnery misses the ship proper, instead impacting the sea; this could still damage the target ship, as the shell may have enough energy to impact beneath the waterline, or if a shell detonated underwater, the shockwave could damage the target ship).

In addition, despite being much larger than the Baltimore class, the secondary battery of the Alaskas was identical, albeit with an improvement in light anti-aircraft battery size. Whereas the Alaska class carried twelve 5"/38 caliber in six twin turrets, fifty-six 40 mm, and thirty-four 20 mm guns, the Baltimore class carried the same number of 5"/38s, eight fewer 40 mm, and ten fewer 20 mm, considerably fewer than new U.S. battleships that had ten (save for {{USS|South Dakota|BB-57|2}}) 5"/38 twin mounts while older refitted U.S. battleships had eight. The lack of anti-aircraft weaponry for a ship of its size was attributed to the amidships aircraft catapult like older US cruisers; while other modern U.S. cruisers and battleships opted for stern-mounted aircraft catapults to free up space along the central superstructure for more secondaries and anti-aircraft guns. In common with U.S. heavy cruisers, they had aircraft hangars and a single large rudder; the single rudder combined with the hull's long length gave the Alaskas a turning radius of {{Convert|800|yard|m|abbr=on}}, which exceeded the turning circles of larger battleships and carriers in the U.S. Navy. Author Richard Worth remarked that when they were finally completed, launched, and commissioned, they had the "size of a battleship but the capabilities of a cruiser". The Alaska class was similarly expensive to build and maintain as contemporary battleships, yet far less capable due to armor deficiencies, while able to put up an anti-aircraft defense comparable only to the much cheaper Baltimore cruisers.

Despite these cruiser-like characteristics, and the U.S. Navy's insistence on their status as cruisers, the Alaska class has been frequently described as battlecruisers. The official navy magazine All Hands said "The Guam and her sister ship Alaska are the first American battle cruisers ever to be completed as such."All Hands, December 1945, "Sleek, Fast, Deadly- Our New CB's" Author Chris Knupp noted that while "other nations fulfilled the battlecruiser role by designing vessels like battleships, but stripped of armor and other features to gain speed", the United States "fulfilled the battlecruiser role by creating a larger, more powerful heavy cruiser...[whose] design already offered less armor and higher speed, but by enlarging the ship they gained the heavier firepower". Armament-wise, the Alaskas{{'}} had much larger guns than contemporary heavy cruisers; while the Baltimore class only carried nine 8"/55 caliber Marks 12 and 15 guns,{{cite web | last = DiGiulian | first = Tony | title = 8"/55 (20.3 cm) Marks 12 and 15 | url = http://www.navweaps.com/Weapons/WNUS_8-55_mk12-15.htm | publisher = Navweaps.com | date = 7 February 2008 | access-date =15 October 2008 | archive-url= https://web.archive.org/web/20081002055750/http://www.navweaps.com/Weapons/WNUS_8-55_mk12-15.htm| archive-date= 2 October 2008 | url-status= live}} the Alaska class carried nine 12"/50 caliber guns that were as good as, if not superior to, the old 14"/50 caliber gun used on the U.S. Navy's pre-treaty battleships.{{cite web | last = DiGiulian | first = Tony | title = 12"/50 (30.5 cm) Mark 8 | url = http://www.navweaps.com/Weapons/WNUS_12-50_mk8.htm | publisher = Navweaps.com | date = 7 February 2008 | access-date =15 October 2008 | archive-url= https://web.archive.org/web/20080921170348/http://www.navweaps.com/Weapons/WNUS_12-50_mk8.htm| archive-date= 21 September 2008 | url-status= live}} The Alaskas{{'}} percentage of armor tonnage, 28.4%, was slightly less than that of fast battleships; the British King George V class, the American Iowa class, and the battlecruiser/fast battleship {{HMS|Hood}} all had armor percentages between 32 and 33%, whereas the Lexington-class battlecruiser design had a nearly identical armor percentage of 28.5%. In fact, older battlecruisers, such as {{sclass|Invincible|battlecruiser|5}} (19.9%), had a significantly lower percentage.Friedman, Battleship Design and Development, 166–173

As built, the Alaska class had nine 12"/50 caliber Mark 8 guns mounted in three triple (3-gun) turrets, with two turrets forward and one aft, a configuration known as "2-A-1". The previous 12" gun manufactured for the U.S. Navy was the Mark 7 version, which had been designed for and installed in the 1912 {{sclass|Wyoming|battleship|2}}s. The Mark 8 was of considerably higher quality; in fact, it "was by far the most powerful weapon of its caliber ever placed in service".Dulin and Garzke, 190. Designed in 1939, it weighed {{convert|121856|lb|kg}} including the breech, and could sustain an average rate of fire of 2.4–3 rounds a minute. It could throw a {{convert|1140|lb|kg|adj=on}} Mark 18 armor-piercing shell {{convert|38573|yd|m|0}} at an elevation of 45°, and had a 344-shot barrel life (about 54 more than the much larger but similar 16"/50 caliber Mark 7 gun found on the Iowa battleships.).{{cite web | last = DiGiulian | first = Tony | title = United States of America 16"/50 (40.6 cm) Mark 7 | url = http://www.navweaps.com/Weapons/WNUS_16-50_mk7.htm | publisher = Navweaps.com | date = 7 February 2008 | access-date =16 October 2008 | archive-url= https://web.archive.org/web/20080921165815/http://www.navweaps.com/Weapons/WNUS_16-50_mk7.htm| archive-date= 21 September 2008 | url-status= live}} The Alaskas{{'}} Mark 8 guns were the heaviest main battery of any cruiser of World War II, and as capable as the old 14"/45 caliber gun used on the U.S. Navy's pre-treaty battleships.

The turrets were very similar to those of the Iowa-class battleships, but differed in several ways; for example, the Alaska class had a two-stage powder hoist instead of the Iowa class's one-stage hoist. These differences made operating the guns safer and increased the rate of fire. In addition, a "projectile rammer" was added to Alaska and Guam. This machine transferred shells from storage on the ship to the rotating ring that fed the guns. However, this feature proved unsatisfactory, and it was not planned for Hawaii or any subsequent ships.

Because Alaska and Guam were the only two ships to mount these guns, only ten turrets were made during the war (three for each ship including Hawaii and one spare). They cost $1,550,000 each and were the most expensive heavy guns purchased by the U.S. Navy in World War II.

The secondary battery of the Alaska class was composed of twelve dual-purpose (anti-air and anti-ship) 5"/38 caliber guns in twin mounts, with four offset on each side of the superstructure (two on each beam) and two centerline turrets fore and aft. The 5"/38 was originally intended for use on only destroyers built in the 1930s, but by 1934 and into World War II it was being installed on almost all of the U.S.'s major warships, including aircraft carriers, battleships, and heavy and light cruisers.{{cite web|last=DiGiulian |first=Tony |title=United States of America 5"/38 (12.7 cm) Mark 12 |url=http://www.navweaps.com/Weapons/WNUS_5-38_mk12.htm |publisher=Navweaps.com |date=27 March 2008 |access-date=25 July 2008 |archive-url=https://web.archive.org/web/20080905181826/http://navweaps.com/Weapons/WNUS_5-38_mk12.htm |archive-date= 5 September 2008 |url-status=dead }}

Medium anti-aircraft armament (a key component of area air defence within a Task Group) on the Alaska-class ships was 56 x 40mm Bofors guns and for close-in air defence they carried 34 × 20 mm guns. These numbers may be compared with; 48 × 40 mm and 24 × 20 mm on the smaller Baltimore-class heavy cruisers, 60 x 40 mm and 36 x 20 mm on the larger battleship North Carolina at the end of the war, and 80 × 40 mm and 49 × 20 mm on the even larger Iowa-class battleships.{{cite DANFS | title = Baltimore | url = http://hazegray.org/danfs/cruisers/ca68.txt | access-date=15 October 2008|short=yes|link=no| archive-url= https://web.archive.org/web/20080906103026/http://www.hazegray.org/danfs/cruisers/ca68.txt| archive-date= 6 September 2008 | url-status= live}}{{cite DANFS | title = Iowa | url = http://hazegray.org/danfs/battlesh/bb61.htm | access-date=15 October 2008|short=yes|link=no| archive-url= https://web.archive.org/web/20080920053724/http://www.hazegray.org/danfs/battlesh/bb61.htm| archive-date= 20 September 2008 | url-status= live}}

• USS Philippines (CB-4), Puerto Rico (CB-5), and Samoa (CB-6) were planned as the fourth, fifth, and sixth ships of the class, respectively. All three ships were to be built at Camden, New Jersey, but they were cancelled before construction could begin.
