The third Iowa (BB-61) was laid down at New York Navy Yard, 27 June 1940; launched 27 August 1942; sponsored by Mrs. Henry A. Wallace, wife of Vice President Wallace, and commissioned 22 February 1943, Capt, John L. McCrea in command.
On 24 February, Iowa put to sea for shakedown in Chesapeake Bay and along the Atlantic Coast. She got underway, 27 August for Argentia, Newfoundland to neutralize the threat of German Battleship Tirpitz which was reportedly operating in Norwegian waters.
In the fall, Iowa carried President Franklin D. Roosevelt to Casablanca, French Morocco on the first leg of his journey to the Teheran Conference in November. After the conference she returned that President to the United States.
As Flagship of Battleship Division 7, Iowa departed the United States 2 January 1944 for the Pacific Theatre and her combat debut in the campaign for the Marshalls. From 29 January to 3 February, she supported carrier air strikes made by Rear Admiral Frederick C. Sherman's task Group against Kwajalein and Eniwetok Attols in the Marshall Islands. Her next assignment was to support air strikes against the Japanese Naval base at Truk, Caroline Islands. Iowa, in company with other ships, was detached from the support group 16 February, 1944 to conduct an anti-shipping sweep around Truk to destroy enemy naval vessels escaping to the north. On 21 February, she was underway with Fast Carrier Task Force 58 while it conducted the fast strikes against Saipan, Tinian, Rota, and Guam in the Marianas.
On 18 March, Iowa, flying the flag of Vice Admiral Willis A. Lee, Commander Battleships, Pacific, joined in the bombardment of Mili Atoll in the Marshall Islands. Although struck by two Japanese 4.7' projectiles during the action, Iowa suffered negligible damage. She then rejoined Task Force 58, 30 March, and supported air strikes against the Palau Islands and Woleai of the Carolinas which continued for several days.
From 22 to 28 April 1944, Iowa supported air raids on Hollandia, Aitape, and Wakde Islands to support Army forces on Aitape, Tanahmerah Bay, and Humboldt Bay in New Guinea. She then joined the Task Force's second strike on Truk, 29-30 April, and bombarded Japanese facilities on Ponape in the Carolinas, 1 May.
In the opening phases of the Marianas campaign, Iowa protected the flattops during air strikes on the islands of Saipan, Tinian, Guam, Rota, and Pagan, 12 June, in an engagement known as the Battle of the Philippine Sea, Iowa helped repel four massive air raids launched by the Japanese Middle Flit. This resulted in the almost complete destruction of Japanese carrier - based aircraft. Iowa then joined in the pursuit of the fleeing enemy Fleet, shooting down one torpedo plane and assisting in splashing another.
Throughout July, Iowa remained off the Marianas supporting air strikes on the Palaus and landings on Guam. After a month's rest, Iowa sortied from Eniwetok as part of the 3d Fleet.=, and helped support the landings on Peleliu, 17 September. She then protected the carriers during air strikes against the Central Philippines to neutralize enemy air power for the long awaited invasion of the Philippines. On 10 October, Iowa arrived off Okinawa for a series of air strikes on the Ryukyus and Formosa. She then sup0ported air strikes against Luzon, 18 October and continued this vital duty during general macArthur's landing on Leyte 20 October.
In a last ditch attempt to halt the United States campaign to recapture the Philippines, the Japanese Navy struck back with a three -p pronged attack in Leyte Gulf. Iowa accompanied TF-38 during attacks against the Japanese Central Force as it steamed through the Sibuyan Sea toward San Bernardino Strait. The reported results of these attacks and the apparent retreat of the Japanese Central Force led Admiral Halsey to believe that this force had been ruined as an effective fighting group. Iowa, with Task Force 38, steamed after the Japanese Northern Force off Cape Engano, Luzon. On 25 October 1944, when the ships of the Northern Force were almost within range of Iowa's guns, word arrived that the Japanese Central Force was attacking a group of American escort carriers off Samar. This threat to the American beachheads forced her to reverse course and steam to support the vulnerable "baby carriers." However, the valiant fight put up by the escort carriers and their screen had already caused the Japanese to retire and Iowa was denied a surface action. Following the Battle for Leyte Gulf, Iowa remained in the waters off the Philippines screening carriers during strikes against Luzon and Formosa. She sailed for the West Coast late in December 1944.
Iowa arrived San Francisco, 15 January 1945, for overhaul. She sailed 19 March 1945 for Okinawa, arriving 15 April 1945. Commencing 24 April 1945, Iowa supported carrier operations which assured American troops vital air superiority during their struggle for that bitterly contested island. She then supported air strikes off southern Kyusyhu from 25 May to 13 June 1945. Iowa participated in strikes on the Japanese homeland 14-15 July and bombarded Muroran, Hokkaido, destroying steel mills and other targets. The city of Hitachi on Honshu was given the same treatment on the night of 17-18 July 1945. Iowa continued to support fast carrier strikes until the cessation of hostilities, 15 August 1945.
Iowa entered Tokyo Bay with the occupation forces, 29 August 1945. After serving as Admiral William F. Halsey's flagship for the surrender ceremony, 2 September 1945, Iowa departed Tokyo Bay 20 September 1945 for the United States.

Radio station: At the end of events associated with the Pacific War, His Majesty Hirohito, the Showa Emperor of Japan, announced on radio on August 15 1945 that the war was over. The Peace Ceremony was signed on board the navy vessel "Missouri" nearly three weeks later, on September 2. The role that radio played in these events forms an important and interesting chapter in international radio history.
At the time of the signing ceremony on the aircraft carrier "Missouri", there were 260 Allied navy vessels at anchor in Tokyo Bay. The "Missouri" itself lay at anchor eighteen miles out in the bay and six miles off the coast of Yokohama. An armada of 1900 planes, airforce and navy, flew overhead.
The USS Missouri was launched in January 1944, the fourth navy vessel to bear this title. It was noted on the air in that era by shortwave listeners in the United States, New Zealand and Australia with the callsign, NCBL.
Another navy vessel, the USS Iowa, also played a major role in the relay of radio signals at the time of the historic events in Tokyo Bay. This ship, the "Iowa", was launched in August 1942, and it was often noted on air under the callsign KU1M calling KU5Q on the island of Guam.
At the time of the signing ceremony, many radio circuits were activated to ensure reliable worldwide coverage. The originating point was the main ship transmitters, NCBL, on the "Missouri". Nearby was the "Iowa" which acted as the network control for these broadcasts with its shortwave transmitters under the callsign KU1M.
The four shortwave transmitters of Radio Tokyo at Nazaki in Japan carried a relay of the broadcast for long distance coverage, which was picked up in Guam, the Philippines and Hawaii for onward relay to the receiving stations in California and elsewhere. And from there of course, the relay became a worldwide radio broadcast phenomenon.
It was on September 2, 1945, at 9:02 am local time that General Douglas MacArthur stepped before the microphone that was set up on the landing deck of the "Missouri" for this historic worldwide broadcast. His wife Jean, was still in the Philippines at the time, living in the German embassy on the edge of Manila. She heard her husband's radio broadcast on a shortwave radio.
There is only one known QSL from these ships in this era. A QSL letter was received by Ray Simpson, the shortwave columnist for the Australian magazine, "Radio & Hobbies". This letter, verifying the reception of KU1M on the "Iowa" in March 1947, was received from the radio section at navy headquarters in California. At the time, the "Iowa" was on navy manoeuvres off the coast of California and it was noted on 9670 kHz. [Story by Dr. Adrian Peterson]
