USS Iowa (BB-61) Battleship

USS Iowa (BB-61) Battleship USS Iowa (BB-61) was the lead ship of the Iowa-class of battleships. The last and largest class of battleship constructed for the US Navy, the Iowa-class ultimately consisted of four ships. Following the pattern set by the preceding North Carolina- and  South Dakota-classes, the Iowa-classs design called for a heavy armament combined with a high top speed. This latter trait allowed them to serve as effective escorts for carriers. Commissioned in early 1943, Iowa was the only member of the class to see extensive service in both the Atlantic and Pacific theaters of  World War II. Retained at the end of the conflict, it later saw combat during the Korean War. Though decommissioned in 1958, Iowa was modernized and brought back into service during the 1980s. Design In early 1938, work commenced on a new battleship design at the behest of Admiral Thomas C. Hart, head of the US Navys General Board. Originally conceived as an enlarged version of the South Dakota-class, the new ships were to mount twelve 16 guns or nine 18 guns. As the design was revised, the armament became nine 16 guns. Additionally, the class anti-aircraft armament underwent several revisions with many of its 1.1 guns being replaced with 20 mm and 40 mm weapons. Funding for the new battleships came in May with the passage of the Naval Act of 1938. Dubbed the Iowa-class, construction of the lead ship, USS Iowa, was assigned to the New York Navy Yard. Intended as the first of four ships (two, Illinois and Kentucky were later added to the class but never completed), Iowa was laid down on June 17, 1940. Construction With the US entry into World War II following the attack on Pearl Harbor, construction of Iowa pushed forward. Launched on August 27, 1942, with Ilo Wallace, wife of Vice President Henry Wallace, as sponsor, Iowas ceremony was attended by First Lady Eleanor Roosevelt. Work on the ship continued for another six months and on February 22, 1943, Iowa was commissioned with Captain John L. McCrea in command. Departing New York two days later, it conducted a shakedown cruise in the Chesapeake Bay and along the Atlantic coast. A fast battleship, Iowas 33-knot speed allowed it to serve as an escort for the new Essex-class carriers that were joining the fleet.

Arriving, it spent the next several weeks in the North Atlantic to protect against a potential sortie by the German battleship Tirpitz which had been cruising in Norwegian waters. By October, this threat had evaporated and Iowa steamed for Norfolk where it underwent a brief overhaul. The following month, the battleship carried President Franklin D. Roosevelt and Secretary of State Cordell Hull to Casablanca, French Morocco on the first part of their journey to the Tehran Conference. Returning from Africa in December, Iowa received orders to sail for the Pacific. Island Hopping Named Flagship of Battleship Division 7, Iowa departed on January 2, 1944, and entered combat operations later that month when it supported carrier and amphibious operations during the Battle of Kwajalein. A month later, it helped cover Rear Admiral Marc Mitschers carriers during a massive aerial attack on Truk before being detached for an anti-shipping sweep around the island. On February 19, Iowa and its sister ship USS New Jersey (BB-62) succeeded in sinking the light cruiser Katori. Remaining with Mitschers Fast Carrier Task Force, Iowa provided support as the carriers conducted attacks in the Marianas. On March 18, while serving as flagship for Vice Admiral Willis A. Lee, Commander Battleships, Pacific, the battleship fired on Mili Atoll in the Marshall Islands. Rejoining Mitscher, Iowa supported air operations in the Palau Islands and Carolines before shifting south to cover Allied attacks on New Guinea in April. Sailing north, the battleship supported air attacks on the Marianas and bombarded targets on Saipan and Tinian on June 13-14. Five days later, Iowa helped protect Mitschers carriers during the Battle of the Philippine Sea and was credited with downing several Japanese aircraft. Leyte Gulf After aiding in operations around the Marianas during the summer, Iowa shifted southwest to cover the invasion of Peleliu. With the conclusion of the battle, Iowa and the carriers mounted raids in the Philippines, Okinawa, and Formosa. Returning to the Philippines in October, Iowa continued to screen the carriers as General Douglas MacArthur commenced his landings on Leyte. Three days later, Japanese naval forces responded and the Battle of Leyte Gulf began. During the course of the fighting, Iowa remained with Mitschers carriers and raced north to engage Vice Admiral Jisaburo Ozawas Northern Force off Cape Engaà ±o. Nearing the enemy ships on October 25, Iowa and the other supporting battleships were ordered to return south to aid Task Force 38 which had come under attack off Samar. In the weeks after the battle, the battleship remained in the Philippines supporting Allied operations. In December, Iowa was one of many ships that were damaged when Admiral William Bull Halseys Third Fleet was hit by Typhoon Cobra. Suffering damage to a propeller shaft, the battleship returned to San Francisco for repairs in January 1945. Final Actions While in the yard, Iowa also underwent a modernization program which saw its bridge enclosed, new radar systems installed, and fire control equipment improved. Departing in mid-March, the battleship steamed west to take part in the Battle of Okinawa. Arriving two weeks after American troops had landed, Iowa resumed its previous duty of protecting the carriers operating offshore. Moving north in May and June, it covered Mitschers raids on the Japanese home islands and bombarded targets on Hokkaido and Honshu later that summer. Iowa continued to operate with the carriers until the end of hostilities on August 15. After overseeing the surrender of the Yokosuka Naval Arsenal on August 27, Iowa and USS Missouri (BB-63) entered Tokyo Bay with other Allied occupation forces. Serving as Halseys flagship, Iowa was present when the Japanese formally surrendered aboard Missouri. Remaining in Tokyo Bay for several days, the battleship sailed for the United States on September 20. Korean War Taking part in Operation Magic Carpet, Iowa aided in transporting American troops home. Arriving at Seattle on October 15, it discharged its cargo before moving south to Long Beach for training operations. Over the next three years, Iowa continued with training, served a stint as flagship of the 5th Fleet in Japan, and had an overhaul. Decommissioned on March 24, 1949, the battleships time in the reserves proved brief as it was reactivated on July 14, 1951 for service in the Korean War. Arriving in Korean waters in April 1952, Iowa began shelling North Korean positions and provided gunfire support for the South Korean I Corps. Operating along the east coast of the Korean Peninsula, the battleship routinely struck targets ashore through the summer and fall. Departing the war zone in October 1952, Iowa sailed for an overhaul in Norfolk. Modernization After conducting a training cruise for the US Naval Academy in mid-1953, the battleship moved through a number of peacetime postings in the Atlantic and Mediterranean. Arriving at Philadelphia in 1958, Iowa was decommissioned on February 24. In 1982, Iowa found new life as part of President Ronald Reagans plans for a 600-ship navy. Undergoing a massive program of modernization, much of the battleships anti-aircraft armament was removed and replaced with armored box launchers for cruise missiles, MK 141 quad cell launchers for 16 AGM-84 Harpoon anti-ship missiles, and four Phalanx close-in weapons systems Gatling guns. In addition, Iowa received a full suite of modern radar, electronic warfare, and fire control systems. Re-commissioned on April 28, 1984, it spent the next two years conducting training and taking part in NATO exercises. Middle East Retirement In 1987, Iowa saw service in the Persian Gulf as part of Operation Earnest Will. For much of the year, it aided in escorting re-flagged Kuwaiti tanker through the region. Departing the following February, the battleship returned to Norfolk for routine repairs. On April 19, 1989, Iowa suffered an explosion in its Number Two 16 turret. The incident killed 47 crewmen and initial investigations suggested that the explosion was the result of sabotage. Later findings reported that the cause was most likely an accidental powder explosion. With the cooling of the Cold War, the US Navy began reducing the size of the fleet. The first Iowa-class battleship to be decommissioned, Iowa moved to reserve status on October 26, 1990. Over the next two decades, the ships status fluctuated as Congress debated the US Navys ability to provide gunfire support of US Marine Corps amphibious operations. In 2011, Iowa moved to Los Angeles where it was opened as a museum ship.
