USS Mobile (CL-63) was a Cleveland-class light cruiser of the United States Navy. She was the third ship named for Mobile, Alabama.

She was laid down on 14 April 1941 by Newport News Shipbuilding and Dry Dock Co., Newport News, Virginia; launched on 15 May 1942; sponsored by Mrs. Harry T. Hartwell; and commissioned on 24 March 1943, Captain Charles J. Wheeler in command.^[1]

Service history[edit]

World War II[edit]

1943[edit]

Following a Chesapeake Bay shakedown and a brief training cruise to Casco Bay, Mobile departed for the Pacific, arriving Pearl Harbor on 23 July 1943 for a month of further training. On 22 August, she sailed west, joining Task Force 15 (TF 15) the following day for a raid on Marcus Island on 31 August. She participated in two more carrier raids from Hawaii before joining the 5th Fleet for the Gilberts campaign. She screened the ships of TF 15 as they struck at Tarawa Atoll on 18 September, and the ships of TF 14 hitting Wake on 5–6 October. On 21 October, she sailed west again in Task Group 53.3 (TG 53.3). By 8 November, she was off Bougainville Island covering reinforcement landings. Thence she steamed to Espiritu Santo, where she joined TG 53.7 for the assault and occupation of Tarawa. From the landings at Betio on the 20th–28th, she remained in the area supporting the Marine assault forces as they fought the first vigorous beachhead opposition to an American amphibious landing.^[1]

On 1 December, Mobile was reassigned to TF 50 (Fast Carrier Forces, Pacific Fleet), the nucleus of what was to become TF 38/58. From the Gilberts, this force moved north for air attacks on Kwajalein and Wotje in the Marshalls. From there, the force returned to Pearl Harbor. Mobile continued on to San Diego, where she arrived and reported for escort duty to Amphibious Forces, 5th Fleet on 29 December.^[1]

1944[edit]

Fifteen days later, sailing with TG 53.5, she began to make her way back to the Marshalls. Detached on 29 January 1944, Mobile, with other of Cruiser Division 13 (CruDiv 13), bombarded Wotje and then rejoined their task force for the assault and occupation of Kwajalein. Until 6 February, she performed fire support and carrier screening duties off Roi and Namur. She then proceeded to Majuro where, on 12 February, she joined TF 58.^[1]

The mission of the fast carrier forces had by this time evolved into sealing off designated enemy-held atolls and islands which the Allies intended to take and interdicting others to isolate and keep to a minimum Japanese resistance at the target. Now a third mission was to be added, the pounding of major enemy bases without the aid of land-based aircraft, leaving little or no need for a return visit. Thus, to ease the occupation of Eniwetok and to aid in the encirclement of Rabaul, TF 58 departed Majuro and sailed for the Carolines. On 16–17 February, they devastated Truk, the best fleet anchorage in the Mandated Territories, the base of the Japanese combined fleet and the center for air and sea communications between Japan and the Bismarck Archipelago. The force then sailed northwest to the Mariana Islands for strikes on Saipan, Tinian, and Guam, encountering heavy aerial resistance there on 21–22 February. After a brief respite for replenishment at Majuro, Mobile sailed to Espiritu Santo, where the ships of TG 58.1 were reorganized as TG 36.1 on 12 March. On 15 March, they steamed northwest to cover Marine forces as they landed on Emirau on 20 March.^[1]

By 24 March, Mobile's first anniversary, she had steamed over 70,000 miles (110,000 km) and participated in 11 operations against the enemy. Three days later, her group once again became TG 58.1 and readied for further strikes on enemy installations. From 29 March to 3 April, they struck at the Palaus, Yap, and Woleai, returning to Majuro on 5 April. Next they supported Allied landings at Aitape, Humboldt Bay, and Tanah Merah Bay in New Guinea, and bombarded Wake Island and Sawar Airfield on 21–22 April. From there, they returned to the Carolines where they conducted air strikes on Truk and bombarded Satawan on 29–30 April, hit Ponape on 1 May, and then headed back to Majuro to replenish and rearm in preparation for the Marianas campaign.^[1]

On 6 June, the carrier force sortied from Majuro again. By 11 June, they were in the Marianas, striking at Saipan, Tinian, Guam, and Rota. From then through 17 June its planes and ships ranged from the Volcano and Bonin Islands to the southernmost Marianas supporting the assault on Saipan and preventing Japanese reinforcements from reaching that beleaguered island and the next target, Guam. On 18 June, searches for a Japanese fleet, reportedly en route from the Philippines, began to the west of the Marianas. The following day the Battle of the Philippine Sea opened with a Japanese carrier-based aircraft attack on the ships covering the Saipan assault. In the ensuing battle, Mobile continued her role as a guardian of the carriers, often dispatching her OS2U Kingfishers on antisubmarine and rescue missions, while planes from the carriers inflicted damage on Japanese aircraft strength and sank the aircraft carrier Hiyō on 20 June, bringing the number of Japanese carriers lost to three, Shōkaku and Taihō having been sunk by the submarines Cavalla and Albacore on 19 June.^[1]

Retiring from the area on 23 June, the carrier force proceeded to Pagan Island, against which strikes were launched on 24 June, and then made for Eniwetok. Thence, on 30 June, they departed for further strikes on the Bonin and Volcano Islands on 4 July, before turning south once again to continue coverage of the Marianas campaign. Commencing daily strikes on Guam and Rota 6 July, the force remained in the area until after the landings on Guam. On 23 July, TG 58.1, with Mobile in the inner protective ring, steamed southwest for raids in the Western Carolines. Three days later they pounded Yap, Ulithi, and Fais, while TGs 58.2 and 58.3 hit the Palaus. On 30 July, TF 58 retired to Saipan, arrivingon 2 August.^[1]

Underway again the same day, they headed back to the Bonin and Volcano Islands. As carrier planes bombed enemy installations on Iwo, Chichi, Ani, and Haha Jimas on 4 August, Mobile was detached with CruDiv 13 and Destroyer Division 46 (DesDiv 46)) to make an anti-shipping sweep in the Chichi Jima area. In the ensuing hours Mobile assisted in the sinking of one destroyer and a large cargo vessel. The following day she participated in the bombardment of Chichi Jima, and then set course for Eniwetok.^[1]

Mobile's fast carrier group, now designated TG 38.3, began with strikes on the Palaus from 6 to 8 September, then sailed west, raiding Mindanao on 9–10 September, and the Visayas, on 12–13 September. On 15 September, the group returned to the Palaus to cover the landings on Peleliu and Angaur. By 18 September the ships of TG 38.3 were headed back to the Philippines. On 21 September, the force's planes struck the Manila area, and on 24 September swept the Visayas again.^[1]

The force sortied from Ulithi once again on 6 October to pave the way for the upcoming Philippine operations. After the carrier planes had struck enemy installations in the Ryūkyūs, Mobile was detached with the destroyers Gatling and Cotten to search for and destroy two enemy ships 30 miles (48 km) distant from the force. Reaching the area, they discovered only one large cargo ship, the other vessel having been disposed of by several of the carrier planes. The three men-of-war quickly sank the cargo ship and rejoined TF 38 for strikes on Formosa and the Pescadores.^[1]

On 13 October, Mobile was again detached and with others of her division formed a screen around the cruisers Canberra and Houston, wryly designated "Cripple Division 1" (CripDiv 1). Mobile and her companions, playing up erroneous reports issued by the Japanese as to the degree of damage inflicted on "the defeated and fleeing" American force, hoped to draw out the Japanese in chase, so that the carrier task force could destroy them. With the discovery of the waiting American force by Japanese scout planes, orders were changed. Canberra and Houston were towed eastward for repairs and Mobile rejoined TG 38.3 on 17 October.^[1]

The next day the force cruised to the east of the northern Philippines and on 20 October guarded the northern air approaches to Leyte as American forces streamed ashore. For the next few days, strikes were conducted throughout the Visayas and on southern Luzon. On 24 October, TG 38.3 was attacked by planes from Vice Admiral Jisaburō Ozawa's Mobile Fleet as they stood by the aircraft carrier Princeton. As the Battle for Leyte Gulf raged over the Philippines, TF 38.3 fought in the Battle off Cape Engaño on 25 October, then pursued the Mobile Fleet back toward Japan. Assigned to search for and destroy crippled enemy vessels and their escorts, Mobile aided in sinking Chiyoda and Hatsuzuki, then turned south to rejoin the main body of TF 38.^[1]

For the next two months, the cruiser continued to operate in support of the Philippine campaign, guarding the carriers as they sent their planes to cover Allied assault forces in the Visayas and on Mindoro. On 26 December, she departed Ulithi for the west coast, arriving 16 days later at Terminal Island California, for overhaul and alterations.^[1]

1945[edit]

Back at Ulithi on 29 March, she continued on to Okinawa, arriving on 3 April, two days after the initial attacks on that Japanese bastion. Assigned to TF 51, Amphibious Forces, Pacific Fleet, for the next two months, she provided fire support, served on antiaircraft and antisubmarine patrols and saw duty as a unit of "flycatcher" groups assigned to detect and destroy Shinyo kamikaze boats before they caused any damage. At the end of May, she arrived at Leyte where she joined TG 95.7, Philippine training group, with which she operated for the remainder of the war.^[1]

Post-War[edit]

On 20 August, she cleared San Pedro Bay and headed north toward Okinawa and Japan for duty supporting the occupation. In September, she conducted several cruises between Japan and Okinawa, transporting liberated prisoners of wars on the first leg of their return to the United States. The following month she cruised in the Sasebo area and on 18 November, with Marine Corps and Navy men embarked, she departed for San Diego. Arriving on 2 December, she conducted another "Magic Carpet" run before steaming to Puget Sound for inactivation. Decommissioned on 9 May 1947, she entered the Reserve Fleet at Bremerton and remained there, in reserve, until 1 March 1959 when she was struck from the Naval Vessel Register. She was sold for scrapping to Zidell Explorations, Inc., on 16 December 1959, and was towed away for scrapping on 19 January 1960.^[1]

Awards[edit]

Mobile received 11 battle stars for her World War II service.^[1]
