In 1950
North Korea invaded South Korea, prompting the United States to intervene in the name of the United Nations. President
Harry S. Truman was caught off guard when the invasion struck, but quickly ordered U.S. Forces stationed in Japan into South Korea. Truman also sent U.S. based troops, tanks, fighter and bomber aircraft, and a strong naval force to Korea to support the Republic of Korea. As part of the naval mobilization
New Jersey was recalled from the mothball fleet to provide seaborne artillery support for U.N. and South Korean troops.
New Jersey was recommissioned at Bayonne on 21 November 1950, Captain David M. Tyree in command, and proceeded to the Caribbean. She sailed from
Norfolk, Virginia 16 April 1951 and arrived from Japan off the east coast of Korea 17 May. Vice Admiral Harold M. Martin, commanding the
United States Seventh Fleet, placed his flag in
New Jersey for the next six months.
New Jersey guns opened the first shore bombardment of her Korean career at
Wonsan 20 May. During her two tours of duty in Korean waters, she was repeatedly called upon for seaborne mobile artillery. In direct support to United Nations troops; or in preparation for ground actions, in interdicting Communist supply and communication routes, or in destroying supplies and troop positions,
New Jersey used her 16-inch guns to fire far beyond the capacity of land artillery, moved rapidly and free from major attack from one target to another, and at the same time could be immediately available to guard aircraft carriers should they require her protection. It was on this first such mission at Wonsan that she received her only combat casualties of the Korean War. One of her men was killed and two severely wounded when she took a hit from a
shore battery on her number one turret and received a near miss
aft to port. Between 23 and 27 May and again 30 May 1951,
New Jersey pounded targets near
Yangyang and
Kansong, dispersing troop concentrations, dropping a
bridge span, and destroying three large ammunition dumps. Air spotters reported Yangyang abandoned at the end of this action, while railroad facilities and vehicles were smashed at Kansong. On 24 May, she lost one of her
helicopters after the crew pushed their chopper to the limit of its fuel searching for a downed aviator. The helicopter crew was able to reach friendly territory and were later returned to their ship. With Admiral
Arthur W. Radford, Commander in Chief Pacific Fleet, and Vice Admiral
C. Turner Joy, Commander Naval Forces Far East aboard,
New Jersey bombarded targets at Wonsan 4 June. At Kansong two days later she fired her main battery at an artillery regiment and truck encampment, with 7th Fleet aircraft spotting targets and reporting successes. On 28 July off Wonsan the battleship was again taken under fire by shore batteries. Several near misses splashed to port, but
New Jersey precision fire silenced the enemy and destroyed several gun emplacements. Between 4 and 12 July,
New Jersey supported a United Nations push in the Kansong area, firing at enemy buildup and reorganization positions. As the
Republic of Korea's First Division hurled itself on the enemy, shore fire control observers saw
New Jersey salvos hit directly on enemy
mortar emplacements, supply and ammunition dumps, and personnel concentrations.
New Jersey returned to Wonsan 18 July, where she destroyed five gun emplacements with five direct hits.
New Jersey sailed to the aid of troops of the Republic of Korea once more on 17 August, returning to the Kansong area where for four days she provided harassing fire by night, and broke up counterattacks by day, inflicting a heavy toll on enemy troops. She returned to this general area yet again 29 August, when she fired in an amphibious demonstration staged behind enemy lines to ease pressure on the Republic of Korea's troops. The next day she started a three-day saturation of the
Changjon area, with one of her own helicopters spotting the results: four buildings destroyed, road junctions smashed, railroad marshaling yards afire, tracks cut and uprooted, coal stocks scattered, and many buildings and warehouses set on fire. Aside from a brief break in firing 23 September to take aboard wounded from the , damaged by gunfire,
New Jersey was heavily engaged in bombarding the Kansong area, supporting the movement of the
U.S. X Corps. The pattern again was harassing fire by night, destruction of known targets by day. Enemy movement was restricted by the fire of her big guns. A bridge, a dam, several gun emplacements, mortar positions,
pillboxes,
bunkers, and two ammunition dumps were demolished. On 1 October 1951, General
Omar Bradley, Chairman of the
Joint Chiefs of Staff, and General
Matthew B. Ridgeway, Commander in Chief Far East, came on board to confer with Admiral Martin. Between 1 and 6 October
New Jersey was in action daily at Kansong,
Hamhung,
Hungnam,
Tanchon, and
Songjin. Enemy bunkers and supply concentrations provided the majority of the targets at Kansong; at the others
New Jersey fired on railroads, tunnels, bridges, an
oil refinery, trains, and shore batteries. She also engaged an enemy gun emplacement with her five-inch (127 mm) gun mounts, which
New Jersey successfully destroyed. The Kojo area was her target 16 October as she sailed in company with , pilots from spotting. The operation was well-planned and coordinated, and excellent results were obtained. Another highly satisfactory day was 16 October, when the spotter over the Kansong area reported "beautiful shooting every shot on target-most beautiful shooting I have seen in five years." This five-hour bombardment leveled ten
artillery positions, and in smashing
trenches and bunkers inflicted some 500 enemy casualties.
New Jersey dashed up the North Korean coast raiding transportation facilities from 1 to 6 November. She struck at bridges, road, and rail installations at Wonsan, Hungnam, Tanchon, Iowon, Songjin, and Chongjin, leaving four bridges destroyed, others badly damaged, two marshaling yards badly torn up, and many feet of track destroyed. With renewed attacks on Kansong and near the Chang-San-Got Peninsula 11 and 13 November,
New Jersey completed her first tour of duty in Korea. Relieved as flagship by ,
New Jersey cleared
Yokosuka for Hawaii,
Long Beach and the Panama Canal, and returned to Norfolk 20 December for a six-month overhaul. Between 19 July 1952 and 5 September, she sailed as flagship for Rear Admiral Harry R. Thurber, who commanded the NROTC midshipman training cruise to
Cherbourg, Lisbon, and the Caribbean. Now
New Jersey prepared and trained for her second Korean tour, for which she sailed from Norfolk 5 March 1953. Shaping her course via the Panama Canal, Long Beach, and Hawaii, New Jersey reached Yokosuka 5 April, and next day relieved as flagship of Vice Admiral Joseph H. Clark, Commander 7th Fleet. On 12 April
New Jersey returned to action by shelling Chongjin; in seven minutes she scored seven direct hits, blowing away half the main communications building there. At
Pusan two days later,
New Jersey manned her rails to welcome the
President of the Republic of Korea and Madame Rhee, and American Ambassador
Ellis O. Briggs.
New Jersey fired on coastal batteries and buildings at Kojo 16 April; on railway track and tunnels near Hungnam 18 April; and on gun emplacements around
Wonsan Harbor 20 April, silencing them in five areas after she had herself taken several near misses. Songjin provided targets 23 April. Here
New Jersey scored six direct 16 inch (406 mm) hits on a railroad tunnel and knocked out two rail bridges. , Korea.
New Jersey provided artillery support for a major air and surface strike on Wonsan 1 May, as 7th Fleet planes both attacked the enemy and spotted for the battleship. She knocked out eleven Communist shore guns that day, and four days later destroyed the key observation post on the island of
Hodo Pando, commanding the harbor. Two days later
Kalmagak at Wonsan was her target.
New Jersey tenth birthday, 23 May 1953, was celebrated at
Incheon with President and Madame Rhee, Lieutenant General
Maxwell D. Taylor, and other dignitaries on board. Two days later
New Jersey returned to action along the west coast at
Chinampo to knock out harbor defense positions. The battleship was under fire at Wonsan 27–29 May, but her five-inch (127 mm) guns silenced the counter-fire, and her 16-inch shells destroyed five gun emplacements and four gun caves. She also hit a target that flamed spectacularly: either a
fuel storage area or an
ammunition dump.
New Jersey returned to the key task of direct support to troops at
Kosong 7 June. On her first mission, she completely destroyed two gun positions, an observation post, and their supporting trenches, then stood by on call for further aid. She then sailed back to Wonsan for a day-long bombardment 24 June, aimed at guns placed in caves. The results were excellent, with eight direct hits on three caves, one cave demolished, and four others closed. Next day she returned to troop support at Kosong, her assignment until 10 July, aside from necessary withdrawal for replenishment. At Wonsan 11–12 July,
New Jersey fired one of the most concentrated bombardments of her Korean duty. For nine hours the first day, and for seven the second, her guns opened fire on gun positions and bunkers on Hodo Pando and the mainland with telling effect. At least ten enemy guns were destroyed, many damaged, and a number of caves and tunnels sealed.
New Jersey smashed radar control positions and bridges at Kojo 13 July, and was once more on the east coast bombline 22–24 July to support South Korean troops near Kosong. These days found her gunners at their most accurate: A large cave, housing an important enemy observation post was closed, the end of a month-long United Nations effort, and a great many bunkers, artillery areas, observation posts, trenches, tanks and other weapons were destroyed. At sunrise on 25 July 1953
New Jersey was off the key port, rail and communications center of Hungnam, pounding coastal guns, bridges, a factory area, and oil storage tanks. She sailed north that afternoon, firing at rail lines and railroad tunnels as she made for Tanchon, where she launched a
whaleboat in an attempt to spot a train known to run nightly along the coast. Her big guns were trained on two tunnels between which she hoped to catch the train, but in the darkness she could not see the results of her six-gun salvo. ==Post Korean War (1953–1967)==
