The USS Guam (CB-2) was an Alaska-class large cruiser built for the United States Navy during World War II. She measured 808 feet 6 inches (246.43 meters) in overall length, with a beam of 91 feet 1 inch (27.76 meters) and a draft of 31 feet 10 inches (9.70 meters). Displacing approximately 29,779 long tons (30,257 metric tons) at design load and up to 34,253 long tons (34,803 metric tons) at full load, she featured a flush deck with a flared bow and a rounded cruiser stern. Her superstructure was prominent, including an armored conning tower with a tall mast and a secondary conning station aft. Powered by four General Electric geared steam turbines and eight oil-fired Babcock & Wilcox water-tube boilers, the USS Guam generated 150,000 shaft horsepower, reaching speeds up to 33 knots (61 km/h). Her cruising range was about 12,000 nautical miles (22,000 km) at 15 knots. She was armed with a main battery of nine 12-inch (305 mm) L/50 Mark 8 guns in three triple turrets, and a secondary armament of twelve 5-inch (127 mm) dual-purpose guns in six twin turrets. Her anti-aircraft defenses included 56 quad-mounted 40 mm Bofors guns and 34 20 mm Oerlikon guns, with fire control provided by multiple gun directors. The ship's armor was substantial, featuring a 9-inch (229 mm) main belt protecting vital machinery spaces and magazines, tapering to 5 inches at the ends. The armor deck was 4 inches thick, and the conning tower was protected by 10.6 inches of armor. The gun turrets had faces 12.8 inches (325 mm) thick, providing significant protection for her main armament. Laid down in February 1942 and launched in November 1943, USS Guam was commissioned in September 1944. Her service was limited due to her late entry into the war, but she participated in operations off Okinawa from March to July 1945, providing anti-aircraft defense for carrier groups and conducting shore bombardments. She also took part in sweeps for Japanese shipping in the East China and Yellow Seas. After Japan's surrender, she aided in the occupation of Korea and transported U.S. Army troops back to the United States. Decommissioned in February 1947, she remained in reserve until being stricken in 1960 and sold for scrap in 1961. The USS Guam served as a notable example of the Alaska-class cruisers, representing the U.S. Navy's heavy cruiser design during the closing chapter of World War II.
