USS Guam was an Alaska-class large cruiser which served with the United States Navy during the last year of World War II. 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 MarchJuly 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 JulyAugust 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.

Guam as she appeared in 1944

The ship was 808 feet 6 inches (246.43 m) long overall and had a beam of 91 ft 1 in (27.76 m) and a draft of 31 ft 10 in (9.70 m). She displaced 29,779 long tons (30,257 t) as designed and up to 34,253 long tons (34,803 t) at full load. The ship had a flush deck with a flared bow and a rounded cruiser stern. She had a large superstructure that included an armored conning tower with a tall tower mast, along with a smaller, secondary conning position further aft.[1] She carried four OS2U Kingfisher or SC Seahawk floatplanes, housed in two hangars,[2] with a pair of aircraft catapults mounted amidships.[3]

The ship was powered by four sets of General Electric geared steam turbines, each driving a screw propeller. Steam for the turbines was generated by eight oil-fired Babcock & Wilcox water-tube boilers, which were vented through a large funnel located amidships. The propulsion system was rated to produce 150,000 shaft horsepower (110,000 kW), generating a top speed of 33 knots (61 km/h; 38 mph). The ship had a cruising range of 12,000 nautical miles (22,000 km; 14,000 mi) at a speed of 15 kn (28 km/h; 17 mph).[1][4]

The ship was armed with a main battery of nine 12 in (305 mm) L/50 Mark 8 guns in three triple gun turrets, two in a superfiring pair forward and one aft of the superstructure.[Note 1] The secondary battery consisted of twelve 5 in (127 mm) L/38 dual-purpose guns in six twin turrets. Two were placed on the centerline superfiring over the main battery turrets, fore and aft, and the remaining four turrets were placed on the corners of the superstructure. The light anti-aircraft battery consisted of 56 quad-mounted 40 mm (1.6 in) Bofors guns and 34 single-mounted 20 mm (0.79 in) Oerlikon guns.[1] A pair of Mk 34 gun directors aided gunlaying for the main battery, while two Mk 37 directors controlled the 5-inch guns and a Mk 57 director aided the 40 mm guns.[5]

The main armor belt was 9 inches (229 mm) thick in the central portion of the hull, where it protected the propulsion machinery spaces and the ammunition magazines, thinning to 5 inches at either end. The main armor deck was 4 in (102 mm) thick. Her conning tower received 10.6 inches (270 mm) of armor plate on the sides. The gun turrets had 12.8-inch (325 mm) thick faces.[1]
