Introduction
War between Japan and the United States had been a possibility that each nation had been aware of, and planned for, since the 1920s. Japan had been wary of American territorial and military expansion in the Pacific and Asia since the late 1890s, followed by the annexation of islands, such as Hawaii and the Philippines, which they felt were close to or within their sphere of influence.
1: Naval Station Pearl Harbor
Following the overthrow of the Hawaiian Kingdom, the United States Navy established a base on the island in 1899. In 1940, President Franklin D. Roosevelt moved the Pacific Fleet from San Diego to Hawaii. The U.S. Pacific Fleet had been stationed at Pearl Harbor since April 1940. In addition to nearly 100 naval vessels, including eight battleships, there were substantial military and air forces.

2: Japanese Preparations
The Japanese intended the attack as a preventive action to keep the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and the United States. On November 26, 1941, a Japanese task force (the Striking Force) of six aircraft carriersAkagi, Kaga, Soryu, Hiryu, Shokaku, and Zuikakudeparted Hittokapu Bay on Kasatka (now Iterup) Island in the Kuril Islands, en route to a position northwest of Hawaii, intending to launch its 408 aircraft to attack Pearl Harbor: 360 for the two attack waves and 48 on defensive combat air patrol (CAP), including nine fighters from the first wave.
Fleet submarines I-16, I-18, I-20, I-22, and I-24 each embarked a Type A midget submarine for transport to the waters off Oahu. On December 6, they came to within 10 nmi (19 km; 12 mi) of the mouth of Pearl Harbor and launched their midget subs at about 01:00 local time on December 7.

3: The Attack
The attack commenced at 7:48 a.m. Hawaiian Time (18:18 GMT). The base was attacked by 353 Imperial Japanese aircraft (including fighters, level and dive bombers, and torpedo bombers) in two waves, launched from six aircraft carriers. Of the eight U.S. Navy battleships present, all were damaged, with four sunk. A total of 188 U.S. aircraft were destroyed; 2,403 Americans were killed and 1,178 others were wounded.

4: The Damage
The Pearl Harbor attack severely crippled US naval and air strength in the Pacific. However, of the eight battleships, all but the Arizona and Oklahoma were eventually repaired and returned to service, and the Japanese failed to destroy the important oil storage facilities on the island. As a result of the dispositions made by Admiral Kimmel, two US aircraft carriers were not in the harbour, however. The USS Enterprise, under Adm. William F. Halsey, was on a mission to reinforce the Wake Island garrison with marine planes and aviators. The USS Lexington was undertaking a similar mission to ferry marine dive-bombers to Midway.
5: Aftermath
The success of the attack on Pearl Harbor was primarily due to the Americans false estimate of the enemys capabilities and intentions. In 1946 a full-scale congressional investigation took place. Prior to the September 11, 2001, attacks, probably no episode in U.S. military history was so thoroughly examined, and on none has a wider divergence of opinion been expressed.
6: Pearl Harbor Today
In 2010, Pearl Harbor was combined with Hickam Air Force Base to create Joint Base Pearl Harbor-Hickam. The base is home to over 18,000 service members. It serves 24,000 family members each year with schools, hospitals, stores, and recreational opportunities. Today, it is home to the USS Arizona Memorial, the Battleship Missouri, the Pacific Aviation Museum, and other must-see places.
