The USS Alaska (CB-1) was the lead ship of the Alaska-class "large cruisers" built for the United States Navy during World War II. Laid down on December 17, 1941, shortly after the U.S. entered the war, and launched in August 1943 by the New York Shipbuilding Corporation in Camden, New Jersey, she was commissioned in June 1944. The vessel measured approximately 808.5 feet in overall length, with a beam of 91 feet 1 inch and a draft of 31 feet 10 inches. She displaced around 29,779 long tons at design load, with full load displacement reaching up to 34,253 long tons. Her superstructure featured a large armored conning tower, a tall mast, and a rounded cruiser stern, with a flush deck and a flared bow. Powering the USS Alaska were four General Electric geared steam turbines, supplemented by eight Babcock & Wilcox water-tube boilers, generating 150,000 shaft horsepower to attain a top speed of 33 knots. Her cruising range was approximately 12,000 nautical miles at 15 knots. Her armament comprised nine 12-inch (305 mm) L/50 Mark 8 main guns in three triple turrets, with secondary armament of twelve 5-inch (127 mm) dual-purpose guns, and a formidable anti-aircraft battery including 56 quad-mounted 40 mm Bofors and 34 20 mm Oerlikon guns. The ship's armor package included a 9-inch belt amidships, a 4-inch deck, and 12.8-inch faces on her gun turrets, with her conning tower protected by 10.6 inches of armor. During her service, USS Alaska saw limited action due to her late commissioning but participated in key operations off Iwo Jima and Okinawa in 1945, providing anti-aircraft defense and shore bombardment. She shot down several Japanese aircraft, including a possible Ohka missile, and contributed to the fleet’s air strikes against Japan. Notably, her anti-aircraft crews engaged enemy aircraft during major battles, including defending against kamikaze attacks and aiding in the destruction of Japanese bombers. After the war, she supported occupation efforts in Korea and China, and participated in Operation Magic Carpet, repatriating U.S. troops. Decommissioned in February 1947, she was placed in reserve, struck in 1960, and sold for scrap in 1961. The USS Alaska remains a significant example of the large cruiser concept, embodying the U.S. Navy’s wartime emphasis on formidable firepower and fleet screening capability.
