USS Alaska was the lead ship of the Alaska class of large cruisers which served with the United States Navy during the end of World War II. 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

Ohka piloted missile. In July–August 1945 she participated in sweeps for Japanese shipping in the East China and Yellow Seas. 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.

Alaska was 808 feet 6 inches (246.43 m)

amidships.[3]

The ship was powered by four sets of

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

40 mm (1.6 in) Bofors guns and 34 single-mounted 20 mm (0.79 in) Oerlikon guns.[1] A pair of Mk 38 gun directors aided gun laying for the main battery,[5] while two Mk 37 directors controlled the 5-inch guns and a Mk 57 director aided the 40 mm guns.[6]

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]

Service history

Alaska was authorized under the Fleet Expansion Act on 19 July 1940, and ordered on 9 September.

fitting-out work was effected. The ship was completed by June 1944, and was commissioned into the US Navy on 17 June, under the command of Captain Peter K. Fischler.[8]

World War II

After her commissioning, Alaska steamed down to

sea trials off Guantánamo Bay, Cuba. On 2 December, she left Cuba for the Pacific, transiting the Panama Canal two days later, and reaching San Diego on 12 December. There her gun crews trained for shore bombardment and anti-aircraft fire.[8]

On 8 January 1945, Alaska left California for Hawaii, arriving in Pearl Harbor on 13 January. There she participated in further training and was assigned to Task Group 12.2, which departed for Ulithi on 29 January. The Task Group reached Ulithi on 6 February and was merged into Task Group 58.5, part of Task Force 58, the Fast Carrier Task Force. Task Group 58.5 was assigned to provide anti-aircraft defense for the aircraft carriers; Alaska was assigned to the carriers Enterprise and Saratoga. The fleet sailed for Japan on 10 February to conduct air strikes against Tokyo and the surrounding airfields. The Japanese did not attack the fleet during the operation. Alaska was then transferred to Task Group 58.4 and assigned to support the assault on Iwo Jima. She served in the screen for the carriers off Iwo Jima for nineteen days, after which time she had to return to Ulithi to replenish fuel and supplies.[8]

Alaska remained with TG 58.4 for the Battle of Okinawa. She was assigned to screen the carriers Yorktown and Intrepid; the fleet left Ulithi on 14 March and reached its operational area southeast of Kyushu four days later. The first air strikes on Okinawa began that day, and claimed 17 Japanese aircraft destroyed on the ground. Here, Alaska finally saw combat, as the Japanese launched a major air strike on the American fleet. Her anti-aircraft gunners destroyed a Yokosuka P1Y bomber attempting to crash into Intrepid. Shortly thereafter, Alaska was warned that American aircraft were in the vicinity. About ten minutes later, her gunners spotted an unidentified aircraft, approaching in what they thought was a threatening manner; they shot down what turned out to be a Grumman F6F Hellcat fighter, though the pilot was uninjured. Later that afternoon, Alaska shot down a second Japanese bomber, a Yokosuka D4Y.[8]

Alaska underway

The following day, the carrier Franklin was badly damaged by several bomb hits and a kamikaze. Alaska and her sister Guam, two other cruisers, and several destroyers were detached to create Task Group 58.2.9 to escort the crippled Franklin back to Ulithi. On the voyage back to port, another D4Y bomber attacked Franklin, though the ships were unable to shoot it down. Gunfire from one of the 5-inch guns accidentally caused flash burns on several men standing nearby; these were the only casualties suffered by her crew during the war. Alaska then took on the role of fighter director; using her air search radar, she vectored fighters to intercept and destroy a Kawasaki Ki-45 heavy fighter. On 22 March, the ships reached Ulithi and Alaska was detached to rejoin TG 58.4.[8]

After returning to her unit, Alaska continued to screen for the aircraft carriers off Okinawa. On 27 March, she was detached to conduct a bombardment of

Ohka piloted rocket-bomb. On 16 April, the ship shot down another three aircraft and assisted with three others. Throughout the rest of the month, her heavy anti-aircraft fire succeeded in driving off Japanese bombers.[8]

Alaska then returned to Ulithi to resupply, arriving on 14 May. She was then assigned to TG 38.4, the reorganized carrier task force. The fleet then returned to Okinawa, where Alaska continued in her anti-aircraft defense role. On 9 June, she and Guam bombarded

Post-war

Reserve fleet in Bayonne, 1953; the two large ships at right are Alaska and Guam

On 30 August, Alaska left Okinawa for Japan to participate in the 7th Fleet occupation force. She arrived in

Bayonne, New Jersey, where she would be berthed in reserve. She arrived there the following day, and on 13 August, she was removed from active service, though she would not be decommissioned until 17 February 1947.[8]

In 1958, the Bureau of Ships prepared two feasibility studies to see if Alaska and Guam were suitable to be converted to 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 too costly, so a second study was conducted. This study left the forward batteries—the two 12-inch triple turrets and three of the 5-inch dual turrets—in place and added a reduced version of the first plan for the aft. This would have cost $82 million, and was still seen as too costly.[11] As a result, the conversion proposal was abandoned and the ship was instead stricken from the Naval Vessel Register on 1 June 1960. On 30 June, she was sold to the Lipsett Division of Luria Brothers to be broken up for scrap.[8]
