Naval Station Pearl Harbor is a United Statesnaval base on the island ofOahu, Hawaii. In 2010, as part of the recommendations of theBase Realignment and Closure (BRAC) commission, the naval station was consolidated with theUnited States Air Force'sHickam Air Force Base to formJoint Base Pearl Harbor–Hickam. Since 1940, Pearl Harbor has been the headquarters of theUnited States Pacific Fleet.[3][4]
Naval Station Pearl Harbor provides berthing and shore side support to surface ships and submarines, as well as maintenance and training. Pearl Harbor can accommodate the largest ships in the fleet, to include dry dock services, and is now home to over 160 commands. Housing, personnel, and family support are also provided and are an integral part of the shore side activities, which encompasses both permanent and transient personnel.
Because Pearl Harbor is the only intermediate maintenance facility for submarines in the Middle Pacific, it serves as host to a large number of visiting submariners.
TheNaval Computer and Telecommunications Area Master Station, Pacific (NCTAMS PAC), Wahiawa, Hawaii is the world's largest communication station. The headquarters site of this shore command is located in the central section of the island of Oahu, approximately three miles north of Wahiawa.
Pearl Harbor is the headquarters for the Hawaii field office of theNaval Criminal Investigative Service.[5]
Following theannexation of Hawaii, Pearl Harbor was refitted to allow for more navy ships. In May 1899,Commander John F. Merry was made naval representative with authority to transact business for the Navy Department and itsBureaus. He immediately assumed control of the Coal Depot and its equipment. To supplement his facilities, he was assigned the Navy tugIroquois and two coal barges. Inquiries that commenced in June culminated in the establishment of the "Naval Station, Honolulu" on 17 November 1899. On 2 February 1900, this title was changed to "Naval Station, Hawaii".
The creation of the Naval Station allowed the Navy Department to explore territorial outposts. In October 1899,Nero andIroquois made extensive surveys and sounding of the waterways to Midway andGuam. One of the reasons for these explorations was to select a possible cable route toLuzon.
A coal famine and an outbreak of thebubonic plague were the only two incidents that hindered the Commandant from fulfilling his duties. Because of the severe coal shortage in September 1899, the Commandant sold coal to theOahu Railway and Land Company and theInter-Island Steam Navigation Company, Ltd. Although this indicated the affinity of economic ties with the Navy, it was to a certain extent counteracted by the quarantine of the naval establishment from December 1899 to February 1900, because of the bubonic plague. Approximately 61 deaths were recorded in Honolulu for this period. Work was consequently delayed on nascent Navy projects in Honolulu Harbor.
From 1900 to 1908, the Navy devoted its time to improving the facilities of the 85 acres (34 ha) that constituted the naval reservation in Honolulu. Under the Appropriation Act of 3 March 1901, this tract of land was improved with the erection of additional sheds and housing. Improvements included a machine shop, smithery and foundry, Commandant's house and stables, cottage for the watchman, fencing, 10-ton wharf crane, and water-pipe system. Pearl Harbor was dredged and the channel enlarged to accommodate larger ships. On 28 May 1903, the first battleship,Wisconsin, entered the harbor for coal and water. However, when the vessels of the Asiatic station visited Honolulu in January 1904,Rear AdmiralSilas Terry complained that they were inadequately accommodated with dockage and water.
Under the above Appropriation Act, Congress approved the acquisition of lands for the development of a naval station at Pearl Harbor and the improvement of the channel to the Lochs. The Commandant, under the direction of theBureau of Equipment, attempted to obtain options on lands surrounding Pearl Harbor that were recommended for naval use. This endeavor was unsuccessful when the owners of the property refused to accept what was deemed to be a fair price. Condemnation proceedings, under the Hawaiian law of eminent domain, were begun on 6 July 1901. The land acquired by this suit included the present Navy Yard,Kauhua Island, and a strip on the southeast coast ofFord Island. The work of dredging the coral reef that blocked Pearl Harbor progressed rapidly enough to allow the gunboatPetrel to proceed to the upper part of Main Loch in January 1905.
One of the early concerns of the growing station was that the Army would make claims on its property. Because of their facilities, as wharves, cranes,artesian wells, and coal supplies, many requests were made by the Army for their use. By February 1901, the Army had made application for the privilege of establishing on Navy docks movable cranes for handling coal and other stores, a saluting battery and a flag staff on the naval reservation, and an artesian well of its own. All these requests were rejected by the Bureau of Equipment on the theory that, once granted, they "will practically constitute a permanent foothold on the property, and end in dividing it between the two Departments, or in the entire exclusion of the Navy Department on the ground of military expediency as established by frequency of use." However, the Army Depot Quartermaster at Honolulu contracted for the sinking of an artesian well on the Naval Station with the Commandant's approval, who, in turn, acted on a recommendation of theBureau of Yards and Docks. The flow of water obtained amounted to over 1.5 million gallons per day, sufficient for all purposes of the Army and Navy. The Bureau of Equipment felt that its word of caution was justified when the Depot Quartermaster in 1902 let it be known that any water used by the Navy from the artesian well was "only given by courtesy of the Army".

Despite the warnings of the Bureau of Equipment, theWar Department, theDepartment of Labor and Commerce, and theDepartment of Agriculture had secured permission to settle on the naval reservation. By 1906, the Commandant believed that it was necessary for the Bureau of Yards and Docks to develop a policy on the future of the station. The docks were being used to a greater extent by the Army transports than by Navy ships, and the Army was actually attempting to get possession of Quarantine Wharf (which was built by the Territorial Government on the Naval Reservation, with the understanding that it could be taken over at any time by the Navy Department upon the payment of its appraised value). In 1903, the Department of Labor and Commerce received about 7 acres (2.8 ha) for an Immigration Station. The Department of Agriculture had, in the meanwhile, secured part of the site intended for a hospital as an experimental station. The Commandant felt that, if the station was going to develop beyond a mere coaling depot, these territorial encroachments on the part of other departments should be stopped, particularly when they were enjoying the benefits of naval appropriations. "On the other hand," he wrote, "if it is the intention to improve Pearl Harbor and eventually abandon this station every effort should be made to begin work there as soon as possible... I am informed that important commercial interests will make a strong effort next year to have Pearl Harbor improved, and I think that will be an opportune time for the Navy Department to make efforts in the same direction."
In 1908, thePearl Harbor Naval Shipyard was established. The period from 1908 to 1919 was one of steady and continuous growth of the Naval Station, Pearl Harbor, with the exception of the discouraging collapse of thedrydock in 1913. The Act of 13 May 1908 authorized the enlargement and dredging of the Pearl Harbor channel and lochs "to admit the largest ships," the building of shops and supply houses for the Navy Yard, and the construction of a drydock. Work on the dock started on 21 September 1909. In April 1910, thebarquentineAmaranth became the fourth deep-sea, cargo-carrying vessel to venture into the newly dredged harbor, having been preceded by the three-masted schoonerW.H. Marston on 8 March, and the schoonerAriel and barkMarston a few days later.Amaranth delivered materials for construction of the dry dock facility.[6] Work progressed satisfactorily on all projects, except the drydock. After much wrangling with Congress to secure an appropriation of over three million dollars for its construction, the drydock was wrecked by "underground pressure". "On February 17, 1913, the entire drydock structure rumbled, rocked, and caved in." The drydock was ceremonially opened to flooding on 21 August 1919, by Mrs.Josephus Daniels, wife of the Secretary of the Navy. In 1917,Ford Island in the middle of Pearl Harbor was purchased for joint Army and Navy use in the development of military aviation in the Pacific.
As theImperial Japanese military pressed its war in China, concern over Japan's intentions caused the U.S. to begin taking defensive measures. On 1 February 1933, the U.S. Navy staged a mock attack on the base at Pearl Harbor as part of a preparedness exercise.[citation needed] The attack "succeeded" and the defense was deemed a "failure".

Theattack on Pearl Harbor by theEmpire of Japan on Sunday 7 December 1941 brought the United States intoWorld War II.[7][8][9][10][11]
Aircraft and midget submarines of theImperial Japanese Navy under the command of AdmiralChuichi Nagumo began bombing Honolulu at the U.S.naval base. Through earlier code breaking activity, the Americans had determined that an attack was likely to occur. However, as the Americans failed to discover Japan's target location, it was believed that the Philippines was the most likely target.[12] At 06:05 on 7 December, the six Japanese carriers launched a first wave of 183 aircraft composed mainly of dive bombers, horizontal bombers and fighters.[13]

The Japanese struck American ships and military installations at 07:51. The first wave attacked airfields of Ford Island. At 08:30, a second wave of 170 Japanese aircraft, mostly torpedo bombers, attacked the fleet anchored in Pearl Harbor. The battleshipArizona was hit with an armor-piercing bomb which penetrated the forward ammunition compartment, sinking it within seconds, killing 1,177 crew members.
The overall death toll was 2,467 people: 2,403 American citizens—2,335 members of theU.S. military and 68civilians—and 64 members of theImperial Japanese Navy.[14] Five U.S. battleships were sunk and the other remaining three were badly damaged. Overall, nine ships of the U.S. fleet were sunk and 21 ships were severely damaged. Three of the 21 would be irreparable. 188 U.S. aircraft were completely destroyed and 159 others were damaged. Japan lost 29 out of the 353 aircraft they attacked with. The attack on Pearl Harbor was the largest attack committed byforeign nationals on American soil inpeacetime and in general prior to theSeptember 11 attacks.
The first shots fired were from the destroyerWard on a midget submarine that surfaced outside of Pearl Harbor;Ward sank the midget sub at approximately 06:55, about an hour before the attack on Pearl Harbor.[15][16]
Just after 3 p.m. on Sunday 21 May 1944 an explosion in a staging area forLanding Ships, Tank (LSTs) and otheramphibious assault ships in West Loch leading to a fire which quickly spread among the ships being prepared forOperation Forager, the invasion of the Japanese-heldMariana Islands. Over the next 24 hours, six LSTs sank, 163naval personnel died and 396 were injured.
A subsequentNaval Board of Inquiry never determined the exact cause of the disaster. But it concluded the initial explosion was caused when amortar round aboardLST-353 detonated during an unloading operation because it was either dropped or went off when gasoline vapours ignited. The incident – together with thePort Chicago disaster two months later – led to major changes in weapon handling practices within the United States Navy.[17][18]
Over the years, Pearl Harbor remained a main base for the US Pacific Fleet afterWorld War II along withNaval Base San Diego. In 2010, the Navy and the Air Force merged their two nearby bases; Pearl Harbor joined withHickam Air Force Base to createJoint Base Pearl Harbor–Hickam.[19]

On 29 January 1964, the Navy base itself was recognized as aNational Historic Landmark district and with theNational Register of Historic Places since 1976. Within its bounds, it contains several other National Historic Landmarks associated with theattack on Pearl Harbor, including theArizona,Bowfin, andUtah. As an active Navy base, many of the historic buildings that contributed to the NHL designation are under threat of demolition and rebuilding.[2]
From 1932 to 1983, the most recognizable structure on the submarine base was the 100-foot-tallEscape Training Tank. A similar tower on Ford Island was converted to anairport control tower during World War II and still stands. Generations of submariners learned to escape in up to 80 feet of water usingbuoyant ascent and were trained in the use of theMomsen lung orSteinke hood. The Steinke hood was replaced by theSubmarine Escape Immersion Equipment in the 2000s.[citation needed]
Bloch Arena located on the base is still in use today and hosted the collegiate Pearl Harbor Basketball Invitational and was home to theHonolulu Chiefs of theAmerican Basketball League. The address is 224 A Avenue, Honolulu, HI 96818.[20]
On 4 December 2019, while the nuclear submarineUSSColumbia was in dry dock at Pearl Harbor, 22 year-old Machinist Mate Auxiliary Fireman Gabriel Romero shot and killed two naval station civilian employees and injured another before shooting and killing himself. Romero was one ofColumbia's crew and been assigned to the armed Topside Roving Patrol aboard the vessel; both weapons involved in the shooting were issued from theColumbia. Later investigation by the Navy determined that Romero was "likely unfit" for service on a submarine and that officers aboard theColumbia had failed to recognize signs of Romero's degrading mental state.[21][22][23]
On October 14, 1992, the US EPA added the Pearl Harbor Naval Complex to theNational Priorities List, a list of sites deemed to require investigation and remediation by the federal levelSuperfund.[24] It is the only such site in Hawaii.
In November 2021, 20,000 gallons of jet fuel spilled fromRed Hill Bulk Fuel Storage Facility, which had 20 tanks, each holding 12.5 million gallons, buried under volcanic rock to protect them from attacks. 5,000 gallons of fuel spilled into the navy's water system. People using the water system were assured the water was safe to drink, until they started noticing it tasted strange.[25] On December 10, Hawaii health officials reported "high levels" ofpetroleum andgasoline in a sample of water from the Red Hillwell fed by anaquifer under a[clarification needed], which had a problem with leaks. Shortly after a November 2021 report of a leak, the US Navy stopped using the fuel storage farm. 93,000 people could not use the navy's water system, and the military was giving water to those who needed it, while some people had to be moved to hotels for several months.[26] It took three months for the water to be found safe, and in 2022 theSecretary of Defense ordered Red Hill to be closed, and the fuel was removed over a period of six months. Further cleanup of the aquifer was taking place, and while the navy said the water was safe, some people had their doubts. In 2024, 2000 families sued the navy.[25]

As part of the 2006Quadrennial Defense Review, the Navy announced in early 2006 that it would shift 60% of its attack submarines to the Pacific by 2010.
USS Missouri (BB-63) ("Mighty Mo" or "Big Mo") is aUnited States NavyIowa-classbattleship, and was the fourth ship of the U.S. Navy to be named in honor of the U.S. state ofMissouri.Missouri was the last battleship built by the United States, and was the site of the surrender of theEmpire of Japan which endedWorld War II.
Missouri was ordered in 1940 and commissioned in June 1944. In thePacific Theater of World War II she fought in the battles ofIwo Jima andOkinawa and shelled the Japanese home islands, and she fought in theKorean War from 1950 to 1953. She was decommissioned in 1955 into theUnited States Navy reserve fleets (the "Mothball Fleet"), but reactivated and modernized in 1984 as part of the600-ship Navy plan, and provided fire support duringOperation Desert Storm in January/February 1991.
Missouri received a total of 11battle stars for service in World War II, Korea, and the Persian Gulf, and was finally decommissioned on 31 March 1992, but remained on theNaval Vessel Register until her name was struck in January 1995. In 1998, she was donated to the USSMissouri Memorial Association and became amuseum ship atPearl Harbor, Hawaii.
