ww2dbasePearl Harbor is a natural lagoon harbor on the south shore of the Hawaiian island of Oahu. The Hawaiians called the harbor mouth and surrounding lands Pu'uloa, meaning Long Hill, and the sprawling inner bays Wai Nomi, meaning Pearl Water.

ww2dbaseWhaling vessels from the United States began frequenting Honolulu Harbor in the early 1800s and a growing US Naval presence followed. In 1820, a newspaper based in Honolulu urged the establishment of a US Navy base in Hawaii to protect American whaling interests. In 1869, when Hawaii was still a sovereign nation, the US Congress appropriated $50,000 to deepen the channels leading into Pearl Harbor.

ww2dbaseAfter King Kalakaua ascended to the Hawaiian throne in March 1874, the United States was granted exclusive rights to enter Pearl Harbor and authority to establish "a coaling and repair station." Upon the annexation of Hawaii by the United States in 1887, the US Navy's presence and their development of the Pearl Harbor anchorage began increasing steadily. The official opening of the 85 acre Navy facility at Pearl Harbor was on November 17, 1899 with the name Naval Station, Honolulu. The name was changed to Naval Station, Hawaii in February 1900. The harbor was dredged deeper and the channel widened to accommodate larger ships. On May, 28 1903, the battleship USS Wisconsin became the first battleship to enter Pearl Harbor for coal and water.

ww2dbaseThe Naval Station continued expanding and in 1908 the Pearl Harbor Naval Shipyard was established. Almost right away work began on a graving dock, Drydock #1, but in 1913 before it was completed it collapsed due to underground pressures. After a blessing from an Hawaiian Priestess to ward off more disaster, construction resumed and the dock opened in 1919.

ww2dbaseIn 1917, the 335 acre 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. The Army established Luke Field on the northwestern half of the island and the Navy operated Naval Air Station Pearl Harbor on the other half (later, Naval Air Station Ford Island).

ww2dbaseIn February 1933, the US Navy conducted Fleet Exercises in Hawaii that included a mock attack on Pearl Harbor. Within the exercise, the attack was "successful" and the harbor defenses were considered to be a "failure."

ww2dbaseIn response to Japan's spreading military influence in Asia, the United States continued to develop the facilities at Pearl Harbor throughout the 1930s. During that time, the Army's air program moved to the new Hickam Field and the Naval Air Station expanded to fill all of Ford Island, with a large seaplane base at one end of the island and a paved 4,500-foot runway down the center.

ww2dbaseIn 1939, the Pacific Fleet Headquarters was transferred from San Diego to Pearl Harbor leading to accelerations in the baseís development. Work was begun on a second large drydock capable of holding a battleship and a smaller third drydock. At the dawning of the 1940s, the Pearl Harbor Naval Base consisted of a Coaling Station, a Net Depot, a fully capable Naval Repair Shipyard, a Submarine Base, a Supply Depot, a Marine Barracks, a Naval Hospital, a 335 acre Air Station, expansive Fuel Storage Tanks, a Weapons and Ammunition Depot, and over 140 berthing locations capable of mooring more than 250 ships.

ww2dbaseOn Sunday morning, December 7, 1941, over 100 US Navy ships were present inside Pearl Harbor in various states of readiness plus a wide variety of yard craft. The Imperial Japanese Navy executed a well planed combined air and submarine attack on Pearl Harbor, as well as on other Army and Navy facilities around the island. US forces sustained very heavy losses in men, ships, and aircraft while the Japanese sustained comparatively light losses. The engagement, which did not even last two hours, was a decisive victory for the Japanese and an unequivocal defeat for the United States.

ww2dbaseLargely untouched in the attacks were the substantial shipyard facilities and fuel storage tanks. Three days after the attack, the seriously damaged Light Cruiser Helena was floated into Drydock #2, the first ship ever to enter this newly completed facility. The repair and salvage capabilities at Pearl Harbor proved to be indispensible over the next days and months. Of the eight battleships in the harbor during the attack, only three were floating at the end of the day. All but two of those that were sunk were refloated within five months and the capsized Oklahoma was righted and refloated 13 months after the attack. Only the Arizona was not salvaged and she remains on the floor of Pearl Harbor still. About the time the last of the ships damaged in the attack was repaired, ships with battle damage from Coral Sea started showing up and the repair functions continued. The Repair Basin and Drydocks were steadily active over the entire course of the war as ships passed to and from the combat zones.

ww2dbasePearl Harbor was also the Fleet Headquarters so the US Navy's command and intelligence functions were centered there. Nearly every operation in the Western Pacific involving US forces was launched, at least conceptually, from Pearl Harbor.

ww2dbasePearl Harbor acted as a vital forward link in the wartime supply chain as well. The westward flow included personnel from the Army, Navy, Marine Corps, and Coast Guard and materiel consisting of all manners of bombs, bullets, and beans. Pearl Harbor was just as vital in the eastward flow of wounded men and damaged ships. Pearl Harborís nickname "Crossroads of the Pacific" became a reality during that time.

ww2dbaseWartime needs called for more expansion to the base facilities. Construction began on a fourth large drydock at the location of the old Coaling Station and also on four new aircraft carrier piers along the edge of the Pearl City Peninsula. All of these went into service in 1944 and are in service still.

ww2dbasePearl Harbor's geography, with its collection of lochs and small bays, lent itself well to the various functions of the base being separated into different locations in and around the harbor. The hazardous operations were naturally situated in the most remote locations and so the Weapons and Ammunition Depot and all ammunition ships were concentrated in the West Loch, well away from the harbor's other functions.

ww2dbaseOn Sunday, May 21, 1944, a small flotilla of LST transport ships was in the West Loch being loaded with ammunition and supplies for the upcoming landings in the Mariana Islands. For reasons that are still in dispute, a mortar round aboard LST-353 exploded and caused a raging fire. The fire burned through the ammunition faster than men could fight it and it quickly spread to other ships, setting off additional explosions. Over a 24 hour period, six ships were damaged to the point that they sank and there were more than 550 casualties. The salvage operations afterward were substantial but because of the secrecy surrounding the pending Marianas operation, the entire salvage effort took place under extremely tight security; so tight that few records of the salvage were created and many questions about the event linger to this day.

ww2dbaseAfter World War II, Pearl Harbor remained a vital base for the US military performing the same functions as during the war. During the Korean and Vietnam conflicts, the ability of the United States to sustain military operations 7,000 miles across the Pacific was due in large measure to the facilities at Pearl Harbor.

ww2dbaseIn 1962, the confines of Ford Island brought the Navy to the same conclusions the Army reached in 1935 and the Naval Air Station was downgraded to an Auxiliary Landing Field. In 1999, it was closed altogether as an active airfield but the land remained part of the Pearl Harbor Naval Base.

ww2dbaseThe base at Pearl Harbor continues to be very active and very important today, although in 2010 there was a change in the facilityís command structure. The Pearl Harbor Naval Base and the adjoining Hickam Air Force Base were combined under a single command and is now called Joint Base Pearl Harbor-Hickam.

ww2dbaseThe Pearl Harbor Naval Base itself is a National Historic Landmark and there are several locations within the base that are themselves National Landmarks, including the USS Arizona Memorial, the USS Utah Memorial, the USS Bowfin Submarine Museum, the USS Missouri Museum, and the Pacific Aviation Museum at Ford Island.

4 Mar 1942 At 0000 hours, US radar operators detected two signals approaching Pearl Harbor, US Territory of Hawaii; they were two H8K flying boats from Wotje, Marshall Islands via French Frigate Shoals (where they took on fuel from submarines I-15 and I-19). At 0130 hours, five PBY Catalina aircraft were launched, armed with torpedoes, to search for the carriers that the Americans thought where the flying boats must have launched from; at the same time, five US Army fighters were launched to attack the flying boats. At 0210 hours and 0230 hours, the two flying boats dropped their payloads uncontested, although the first bombs fell harmlessly in the mountains 10 miles from Pearl Harbor and the second bombs landed in the water just outside of Pearl Harbor. The two aircraft flew back to Wotje unscathed.
6 Mar 1942 Joseph Rochefort's cryptanalytic team at Pearl Harbor, US Territory of Hawaii began noticing a target location code named AF appearing in Japanese Navy radio messages, and that this target might be struck within a short time.
10 Mar 1942 At Pearl Harbor, US Territory of Hawaii, Joseph Rochefort concluded that the target AF which had appeared in Japanese radio messages in the past few days referred to either Johnston, Palmyra, or Midway, and he promptly sent out warnings to all three locations. Privately, he reported to his superiors that Midway was the likely target.
11 Mar 1942 USS Enterprise arrived at Pearl Harbor, US Territory of Hawaii.
25 Mar 1942 Joseph Rochefort's cryptanalytic team in Pearl Harbor, US Territory of Hawaii intercepted a Japanese Navy message that mentioned a campaign against a location with code name RZP.

21 Apr 1942 Joseph Rochefort's cryptanalytic team based in Pearl Harbor, US Territory of Hawaii intercepted a Japanese Navy radio message noting that Carrier Division 5 (Shokaku and Zuikaku) were being detached from the Mobile Force for operations with the 4th Fleet in the South Pacific.
22 Apr 1942 Joseph Rochefort's cryptanalytic team based in Pearl Harbor, US Territory of Hawaii detected a concentration of Japanese warships at Rabaul, New Britain, including five carriers; while they correctly determined that Shokaku, Zuikaku, and Shoho being at Rabaul, they had mistakenly placed two others (including Kaga) at this location.
24 Apr 1942 Joseph Rochefort's cryptanalytic team based in Pearl Harbor, US Territory of Hawaii had intercepted Japanese Navy radio messages mentioning the existence of task forces bearing names such as MO Covering Force, MO Attack Force, RZP Occupation Force, RXB Occupation Force, etc. Rochefort would quickly arrive at the hypothesis that these task forces were organized for an attack in the Port Moresby, Australian Papua region.
27 Apr 1942 Joseph Rochefort's cryptanalytic team at Pearl Harbor, US Territory of Hawaii decrypted a radio message from Nobutake Kondo to Tokyo, Japan requesting navigation charts of the Aleutian Islands area and latest intelligence at AOE and KCN (which was determined to be Dutch Harbor and Kodiak in the Aleutian Islands).
27 Apr 1942 Joseph Rochefort's cryptanalytic team based in Pearl Harbor, US Territory of Hawaii reported that the Japanese Navy had changed call signs of some major warships, possibly indicating that a major operation was about to take place.
30 Apr 1942 At Pearl Harbor, US Territory of Hawaii, Joseph Rochefort sent Chester Nimitz a report regarding Rochefort's hypothesis that the Japanese might soon be striking at Port Moresby, Australian Papua. Since radio intercepts made mention of multiple targets, he concluded that Tulagi in the Solomon Islands was also a likely target.
1 May 1942 Chester Nimitz departed Pearl Harbor, US Territory of Hawaii and later in the day arrived at Midway Atoll.
2 May 1942 Joseph Rochefort's cryptanalytic team in Pearl Harbor, US Territory of Hawaii intercepted a radio message from Nobutake Kondo's chief of staff regarding the formation of task forces for an offensive operation.

11 May 1942 Joseph Rochefort's cryptanalytic team in Pearl Harbor, US Territory of Hawaii intercepted a radio message from Nobutake Kondo noting that the occupation force for the upcoming campaign would proceed to Saipan, Mariana Islands to await the launch of the operation. Rochefort determined that this occupation force was likely to sail east rather than south, and Midway Atoll was a likely target.
12 May 1942 Chester Nimitz, based in Pearl Harbor in US Territory of Hawaii, received orders from Ernest King to withdraw William Halsey's carrier task force from areas near Japanese land-based aircraft, but Halsey was to remain in South Pacific region.
13 May 1942 Chester Nimitz, based in Pearl Harbor in US Territory of Hawaii, informed Ernest King that the next Japanese offensive would likely be aimed at Nauru and Ocean Islands, but it was also possible that the following offensive might be targeting the Hawaiian Islands or even the west coast of the United States, thus King should allow the two carriers currently in the South Pacific to move to the Central Pacific. In the evening, he secretly ordered William Halsey to conduct a show of force with his carrier force in the Tulagi, Solomon Islands area to deter the Japanese from moving against Nauru and Ocean Islands.
13 May 1942 Joseph Rochefort's cryptanalytic team in Pearl Harbor, US Territory of Hawaii intercepted a radio message of Japanese warships requesting navigation charts of the Oahu, Hawaii area. Some time later, the team intercepted a message ordering aircraft transport ship Goshu Maru to embark the seaplane unit at Emidj island, Jaluit Atoll, Marshall Islands and sail to Saipan, Mariana Islands to join the AF campaign. Realizing that AF must already have a seaplane base or was a good location for a future seaplane base, Rochefort further confirmed that AF was Midway Atoll. Later in the evening, he sent this report to Chester Nimitz and the naval leadership in Washington DC, United States.
14 May 1942 Joseph Rochefort presented his Midway Atoll theory to Chester Nimitz's war plans officer Lynde McCormick. McCormick spent hours at Rochefort's office at the basement of the main navy building in Pearl Harbor, US Territory of Hawaii and was convinced that Rochefort's theory was likely correct. McCormick would return to Nimitz and would convince Nimitz to agree to this theory.
16 May 1942 Joseph Rochefort's cryptanalytic team in Pearl Harbor, US Territory of Hawaii intercepted a Japanese radio message containing Chuichi Nagumo's request for weather reports to be submitted to him at a location 50 miles northwest of AF starting from three hours prior to the pre-determined time of attack.
17 May 1942 USS Flying Fish departed Pearl Harbor, US Territory of Hawaii for her first war patrol.
18 May 1942 At Pearl Harbor, US Territory of Hawaii, Edwin Layton informed Joseph Rochefort that while Chester Nimitz would like to receive further evidence that Midway Atoll was indeed the next Japanese target. Meanwhile, Chester Nimitz ordered William Halsey to bring his carrier group back to the Hawaiian Islands as a precaution.
18 May 1942 USS Hornet departed Pearl Harbor, US Territory of Hawaii for Midway Atoll.
19 May 1942 US Navy intelligence officer Lieutenant Commander Jasper Holmes arrived at the idea that Midway Atoll could send out a fake message regarding the water distiller breaking down, thus the base desperately needed a supply of fresh water. Holmes' superior Joseph Rochefort gave him the permission to execute this idea in the hopes that the Japanese would pick up this message and provide Rochefort's team a clue on whether the Japanese Navy's reference of AF pointed at Midway Atoll. Rochefort's team also began to find the mention of a new code name, MI, in Japanese messages starting on this date; Rochefort quickly determined it to be the operational code name for the strike on Midway Atoll.
20 May 1942 The Japanese, having intercepted the fake message regarding Midway Atoll's water distiller breaking down, reported to the invasion fleet the news and advised the fleet to take on additional supplies of fresh water. This message was intercepted by the US Navy radio intelligence team at Pearl Harbor, US Territory of Hawaii, and it allowed the US to confirm that the target of the next Japanese offensive was indeed Midway Atoll. In response, US Navy and Marine Corps dispatched reinforcements to Midway Atoll and the Aleutian Islands in expectation of an assault. On the same day, US Navy intelligence also intercepted a Japanese message containing the order of battle for the Midway Atoll and Aleutian Islands assaults; this message would be decrypted over the next several days.
