Warships of the US Navy: Large Cruisers, Alaska-class, USS Alaska (CB-1), and USS Guam (CB-2)

Alaska-class cruisers of the US Navy

The Alaska-class were six large cruisers ordered before the Second World War 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 (which were mostly named after states) and smaller heavy and light cruisers (which were named after cities).

The idea for a large cruiser class originated in the early 1930s when the USN sought to counter the Deutschland-class "pocket battleships" being launched by Germany. Planning for ships that eventually evolved into the Alaska-class began in the late 1930s after the deployment of Germany's Scharnhorst-class battleships and rumours that Japan was constructing a new large cruiser class, the B-65 "super cruiser." To serve as "cruiser-killers" capable of seeking out and destroying these post-treaty heavy cruisers, the class was given large guns of a new and expensive design, limited armour protection against 12-inch shells, and machinery capable of powering these warships at speeds of about 31–33 knots (57–61 km/h; 36–38 mph).

Of the six planned, Alaska and Guam were the only two to be commissioned; a third, Hawaii, was close to completion at the war's end and had its construction suspended on 16 April 1947, while the remaining three were cancelled. Alaska and Guam served with the USN for the last year of the Second World War as bombardment ships and fast carrier escorts. They were decommissioned in 1947 after spending only 32 and 29 months in service, respectively. (Wikipedia)

USS Alaska was the lead ship of theAlaska-class "large cruisers" which served with the United States Navy during the end of the Second World War. 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 (61 km/h; 38 mph).

Due to being commissioned late in the war, Alaska saw relatively limited service. She participated in operations off Iwo Jima and Okinawa in February–July 1945, including providing anti-aircraft defense for various carrier task forces and conducting limited shore bombardment operations. He anti-arcraft crews shot down several Japanese aircraft off Okinawa, including a possible Ohka piloted missile. In July–August 1945 she participated in sweeps for Japanese shipping in the East China and Yellow Seas. After 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. (Wikipedia)

USS Guam was an Alaska-class large cruiser which served with the United States Navy during the last year of the Second World War. 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. (Wikipedia)
