The Alaska class cruisers were a class of six cruisers ordered prior to World War II for the United States Navy. Against typical U.S. battleship and cruiser naming practices,[A 5] all were named after "territories or insular areas" of the United States.[A 6]
Of the six that were planned, only three were laid down; two were completed, and the third's construction was suspended on 16 April 1945 when she was 84% complete. The finished two, Alaska and Guam, served with the U.S. Navy for the last two years of World War II as bombardment ships and fast carrier escorts. They were both decommissioned in 1947 after spending only 32 and 29 months in service, respectively.
The idea for a U.S. battlecruiser class originated in the early 1930s, when the U.S. Navy wanted a counter to the "pocket battleships" (Deutschland class) that were being launched and commissioned by Germany. Though nothing resulted immediately, planning for ships that eventually evolved into the Alaska class began in the later 1930s after the deployment of Germany's Scharnhorst class and rumors that Japan was constructing a new battlecruiser class.[11][A 7] The Alaska class were intended to serve as "cruiser-killers", capable of seeking out and destroying these post-Treaty heavy cruisers. To facilitate this, they were given large guns of a new and expensive design, limited armor protection against 12-inch shells, and machinery capable of speeds of about 31–33 knots (36–38 mph, 58–61 km/h).
Design and service
Genesis
Heavy cruiser development was steadied between World War I and World War II by the terms of the Washington Naval Treaty and successor treaties and conferences. In this treaty, the United States, Britain, Japan, France, and Italy had agreed to limit heavy cruisers to 10,000 tons displacement with 8-inch main armament. U.S. cruisers designed between the wars followed this pattern. After the Treaty was effectively lapsed in 1939, the designs were slightly enlarged into the Baltimore-class cruiser.[12]
The initial impetus for the design of the Alaska class came from the deployments of the so-called "pocket battleships" in the early 1930s. Though no actions were taken immediately, plans were revived in the late 1930s when intelligence reports indicated Japan was planning or building "super cruisers" which were much more powerful than U.S. heavy cruisers.[3][6][7][13][A 8] The Navy responded in 1938, when a request from the General Board was sent to the Bureau of Construction and Repair for a "comprehensive study of all types of naval vessels for consideration for a new and expanded building program".[14] The U.S. President at the time, Franklin Delano Roosevelt, might have inspired the idea for the class with his desire to counter the raiding abilities of Japanese cruisers and German "pocket battleships",[15] but these claims are difficult to verify.[6][16]
Design process
One historian described the design process of the Alaska class as "torturous" due to the numerous changes and modifications made to the ships' layouts by numerous departments and individuals.[11] Indeed, plans resulted in at least nine different layouts,[17] ranging from 6,000-ton Atlanta-class antiaircraft cruisers[15] to "overgrown" heavy cruisers[11] and a 38,000-ton mini-battleship that would have been armed with twelve 12-inch and sixteen 5-inch guns.[15] The General Board, in an attempt to keep the displacement under 25,000 tons, allowed the designs to offer only limited underwater protection. As a result, the Alaska class, when built, were vulnerable to torpedoes and shells that fell short of the ship.[18] The final design chosen was a scaled-up Baltimore class that had the same machinery as the Essex-class aircraft carriers. This ship combined a main armament of nine 12-inch guns with protection against 10-inch gunfire into a hull that was capable of 33 knots.[13]
The new class was officially ordered in September 1940 along with a plethora of other ships as a part of the Two-Ocean Navy Act.[7][19][A 9] The new ships' role had been altered slightly; in addition to their surface-to-surface role, they were planned to protect carrier groups. Because of their bigger guns, greater size and increased speed, they would be more valuable in this role than heavy cruisers, and they would also provide insurance against reports that Japan was building "super cruisers" more powerful than U.S. heavy cruisers.[7]
Possible conversion to aircraft carriers
![](http://upload.wikimedia.org/wikipedia/commons/thumb/8/8f/USS_Alaska_%28CB-1%29_launching.jpg/170px-USS_Alaska_%28CB-1%29_launching.jpg)
Yet another drastic change was considered during the "carrier panic" of early 1942. At this point, with Saratoga out until at least May for repairs after torpedo damage and Lexington lost in the Battle of the Coral Sea, the Navy and the President realized that the United States needed more aircraft carriers as quickly as possible. As a result, the Bureau of Ships decided to convert a few hulls that were currently under construction to carriers. At different times during 1942, they considered converting some of the Cleveland-class light cruisers, a few of the Baltimore-class heavy cruisers, all six of the Alaska class, or even one of the Iowa-class battleships.[20]
A conversion of the Alaska cruisers to carriers was "particularly attractive"[20] because of the many similarities between the design of the Essex-class aircraft carriers and the Alaska class, including the same machinery.[21] However, when Alaska cruisers were compared to the Essex carriers, converted cruisers would have had a shorter flight deck (so they could have carried only 90% of the aircraft),[20] would have been 11 feet lower in the water, and could travel 8,000 miles fewer at 15 knots (17 mph). In addition, the large cruiser design did not include the massive underwater protections found in normal carriers due to the armor weight devoted to counter shell fire. In the end, the Cleveland class was chosen since it addressed the foremost concern: speed of production.[22]
Construction
Of the six Alaska-class cruisers that were planned, only three were laid down. The first two, Alaska and Guam, were completed. Construction on Hawaii, the third, was suspended on 16 April 1947 when she was 84% complete.[3][14] 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 shortages[23] 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".[6] As a result, construction of the last three members of the class never began, and they were officially canceled on 24 June 1943.[24][25][26]
Service history
![](http://upload.wikimedia.org/wikipedia/commons/thumb/1/11/Aerial_view_of_USS_Guam_%28CB-2%29_off_Trinidad%2C_13_November_1944_%28NH_97132%29.jpg/220px-Aerial_view_of_USS_Guam_%28CB-2%29_off_Trinidad%2C_13_November_1944_%28NH_97132%29.jpg)
Alaska and Guam served with the U.S. Navy in the last years of World War II. Similar to the Iowa-class fast battleships, their speed made them useful as shore bombardment ships and fast carrier escorts. Both protected Franklin 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. 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 only encountered Chinese junks.[1][2] By the end of the war, the two had become celebrated within the fleet as excellent carrier escorts.[9]
After the war, both ships were decommissioned and "mothballed" in 1947[1][2] after having spent 32 and 29 months in service, respectively.[15] 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, this was seen as cost-prohibitive, so a second study was initiated. This 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 this would have cost approximately half as much as the first study's plan ($82 million), it was still seen as too expensive.[27] 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.[1][2]
The still-incomplete Hawaii was considered for a conversion to be the Navy's first guided-missile cruiser for a time;[A 10] this lasted until 26 February 1952, when a different conversion to a "large command ship" was contemplated. In anticipation of this, her classification was changed to CBC-1. This would have made her a "larger sister" for Northampton,[6] 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.[3]
"Large cruisers" or "battlecruisers"?
![](http://upload.wikimedia.org/wikipedia/commons/thumb/d/d1/USS_Missouri_%28BB-63%29_and_USS_Alaska_%28CB-1%29_at_Norfolk%2C_Virginia%2C_1944.jpg/220px-USS_Missouri_%28BB-63%29_and_USS_Alaska_%28CB-1%29_at_Norfolk%2C_Virginia%2C_1944.jpg)
Early in the class' development, the class used the designation CC, which signified that they were to be battlecruisers in the tradition of the Lexington class;[A 11] however, the designation was later changed to CB to reflect their new name, "large cruiser", and the practice of referring to them as battlecruisers was officially discouraged.[16] The U.S. Navy named the individual vessels after U.S. territories, rather than states (as was the tradition with battleships) or cities (for which cruisers were named), to symbolize the belief that these ships were supposed to play a intermediate role between heavy cruisers and fully-fledged battlecruisers. However, when they were finally completed, launched, and commissioned, they had the "size of a battleship but the capabilities of a cruiser".[11] Apart from Saratoga, members of the Alaska class were the least maneuverable ships in the U.S. Navy[11] due to the decision to use a cruiser-like single rudder instead of a battleship-like dual.[16] They resembled contemporary battleships in appearance, and weighed only 5,000 tons less in displacement. They also mounted the familiar 2-A-1 main battery,[A 12] massive columnar mast, and cluster of 5"/38 caliber dual-purpose guns along the sides of the superstructure. Additionally, while the battleships carried eight (older refitted ships) or ten (post-South Dakota) 5"/38 twin mounts flanking the superstructure, the Alaska cruisers only carried six: four at the superstructure corners, and one at each fore and aft on the centerline.[28][29]
There are two main arguments for referring to the Alaska class as "large cruisers". The first is their armor; while they were able to withstand more fire from guns than any other cruiser afloat, they were virtually defenseless against torpedoes, as they had no sub-divisions within the hull and no anti-torpedo scheme.[11] The lack of underwater protection would also make them vulnerable to shells which fell slightly short of their mark and continued underwater to hit the hull. The second lies entirely in their design. The design of the Alaska-class ships was, from the keel up, just a scaled-up Baltimore-class cruiser.[A 13] In addition, despite being much larger than the Baltimore class, the secondary battery of the "large cruisers" was only slightly larger. Whereas the Alaska class carried twelve 5"/38 caliber, 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 only ten fewer 20 mm.[6]
Despite these cruiser-like characteristics, and the U.S. Navy's insistence on their status as cruisers, the Alaska class were frequently described as battlecruisers at the time.[30] Some modern historians take the view that this a more accurate designation [10] for two main reasons: firstly, they were, in terms of displacement, about twice as heavy as the newest heavy cruisers (the Baltimore class).[30] Secondly, they had much larger guns; while 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,[31] the Baltimore class had an equal number of 8"/55 caliber Marks 12 and 15 guns.[32]
Armament
Main battery
![](http://upload.wikimedia.org/wikipedia/commons/thumb/5/59/USS_Guam_%28CB-2%29_firing_main_battery%2C_1944-45.jpg/220px-USS_Guam_%28CB-2%29_firing_main_battery%2C_1944-45.jpg)
As built, the Alaska class had nine 12"/50 caliber Mark 8 guns mounted in three triple (3-gun) turrets,[31] 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 and installed in the 1912 Wyoming-class battleships. 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."[33] Designed in 1939, it weighed 121,856 pounds (55,273 kg), including the breech, and could sustain an average rate of fire of 2.4–3 rounds a minute. It could throw a 1,140 lb. (517.093 kg) Mark 18 armor piercing shell 38,573 yards (35,271 meters) at an elevation of 45°, while the guns had a 344-shot "barrel life"[31] (comparable to the 16"/50 caliber Mark 7 gun found in the Iowa battleships, Alaska cruisers could fire about 54 more shots).[34]
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 Iowa-class's one-stage hoist. This made operating the guns safer and increased the rate of fire. Also, 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.[31]
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 the Navy $1,550,000 each and were the most expensive heavy guns purchased by the U.S. Navy in World War II.[16]
Secondary battery
The secondary battery of the Alaska class was composed of twelve dual-purpose (anti-air and anti-ship) 5"/38 caliber guns in twin turrets, with four turrets 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.[35]
Anti-aircraft battery
![](http://upload.wikimedia.org/wikipedia/commons/thumb/e/e8/40mm_gun_practice_on_USS_Alaska_%28CB-1%29%2C_1945.jpg/220px-40mm_gun_practice_on_USS_Alaska_%28CB-1%29%2C_1945.jpg)
For anti-aircraft armament, the Alaska class ships carried 56 x 40mm guns and 34 x 20mm guns. These numbers are comparable to 48 x 40mm and 24 x 20mm on the smaller Baltimore class heavy cruisers and 80 x 40mm and 49 x 20mm on the larger Iowa battleships.[1][36][37]
Bofors 40mm anti-aircraft guns
Arguably the most efficient light anti-aircraft gun of World War II, the 40mm Bofors was used on nearly every major warship in the U.S. and U.K. fleets during World War II from about 1943 to 1945. Although they were a descendant of German and Swedish designs, the Bofors mounts used by the United States Navy during World War II had been heavily "Americanized"; this brought the guns up to U.S. Navy standards. This resulted in a gun system set to English standards (now known as the Standard System) with interchangeable ammunition, simplifying the logistics situation for World War II. When coupled with hydraulic couple drives to reduce salt contamination and the Mark 51 director for improved accuracy, the 40mm Bofors became a fearsome adversary, accounting for roughly half of all Japanese aircraft shot down between 1 October 1944 and 1 February 1945.[38]
Oerlikon 20mm anti-aircraft guns
The Oerlikon 20mm anti-aircraft gun was one of the most extensively used anti-aircraft guns of World War II; the U.S. alone manufactured a total of 124,735 of these guns. When activated in 1941, they replaced the 0.50" M2 Browning machine gun on a one-for-one basis. The Oerlikon gun remained the primary anti-aircraft weapon of the United States Navy until the introduction of the 40mm Bofors in 1943.[39]
Ships
- USS Alaska (CB-1) was commissioned on 17 June 1944. She served in the Pacific, screening aircraft carriers, providing shore bombardment at Okinawa, and going on raiding missions in the East China Sea. She was decommissioned on 17 February 1947 after less than three years of service and was scrapped in 1960.[1]
- USS Guam (CB-2) was commissioned on 17 September 1944. She served in the Pacific with Alaska on almost all of the same operations. Along with Alaska, she was decommissioned on 17 February 1947 and was scrapped in 1961.[2]
- USS Hawaii (CB-3) was intended as a third ship of the class, but she was never completed. Numerous plans to utilize her as a guided-missile cruiser or a large command ship in the years after the war were fruitless, and she was scrapped.[3]
- USS Philippines (CB-4) was planned as the fourth ship of the class. She was to be built at Camden, New Jersey, but was canceled before construction could begin.[24]
- USS Puerto Rico (CB-5) was planned as the fifth ship of the class. She was to be built at Camden, New Jersey, but was canceled before construction could begin.[25]
- USS Samoa (CB-6) was planned as the sixth ship of the class. She was to be built at Camden, New Jersey, but was canceled before construction could begin.[26]
