The attack on Pearl Harbor was a surprise attack against the United States' naval base at Pearl Harbor, Hawaii by the Japanese navy, on the morning of Sunday, December 7, 1941, resulting in the United States becoming involved in World War II. It was intended as a preventive action to remove the US Pacific Fleet as a factor in the war Japan was about to wage against Britain, the Netherlands, and the United States. Two aerial attack waves, totaling 353 aircraft, launched from six Japanese aircraft carriers, intending to reduce or eliminate United States' military power in the Pacific.

The attack wrecked two U.S. Navy battleships, one minelayer, and two destroyers beyond repair, and destroyed 188 aircraft; personnel losses were 2,388 killed and 1,178 wounded. Damaged warships included three cruisers, a destroyer, and six battleships (one deliberately grounded, later refloated and repaired; two sunk at their berths, later raised, repaired, and eventually restored to Fleet service). Vital fuel storage, shipyard, maintenance, and headquarters facilities were not hit. Japanese losses were minimal, at 29 aircraft and five midget submarines, with 65 servicemen killed or wounded.

The intent of the strike was to protect Imperial Japan's advance into Malaya and the Dutch East Indies — for their natural resources such as oil and rubber — by neutralizing the U.S. Pacific Fleet. Both the U.S. and Japan had long-standing contingency plans for war in the Pacific, continuously updated as tension between the two countries steadily increased during the 1930s. Japan's expansion into Manchuria and French Indochina were greeted with steadily increasing levels of embargoes and sanctions by the United States and others. In 1940, under the Export Control Act, the U.S. halted shipments of airplanes, parts, machine tools, and aviation gasoline, which Japan saw as an unfriendly act. Nevertheless, the U.S. continued to export oil to Japan, in part because it was understood in Washington cutting off oil exports would be an extreme step, given Japanese dependence on U.S. oil exports, likely to be taken as a provocation by Japan. In the summer of 1941, after Japanese expansion into French Indochina, the U.S. ceased oil exports to Japan, in part because of new American restrictions on domestic oil consumption. President Franklin D. Roosevelt had earlier moved the Pacific Fleet to Hawaii and ordered a buildup in the Philippines, hoping to deter Japanese aggression in the Far East. The Japanese high command was (mistakenly) certain an attack on the United Kingdom's colonies would bring the U.S. into the war, so a preventive strike appeared to be the only way Japan could avoid U.S. interference in the Pacific.

The attack was one of the most important engagements of World War II. Occurring as it did before a formal declaration of war, it pushed U.S. public opinion from isolationism to an acceptance war was unavoidable, as Roosevelt called December 7, 1941 "... a date which will live in infamy."

Background to conflict

Pearl Harbor on 30 October 1941.

War between Japan and the United States had been a possibility each nation had been aware of (and developed contingency plans for) since the 1920s, though tension did not begin to grow serious until Japan's 1931 invasion of Manchuria. Over the next decade, Japan continued to expand into China leading to all out war between the two in 1937. In 1940, Japan invaded French Indochina, partly in an effort to control supplies reaching China, and partly as a first step to improve her access to resources in Southeast Asia. This move prompted an American embargo on oil exports to Japan, which in turn caused the Japanese to decide to commence the planned takeover of oil supplies in the Dutch East Indies.

Preliminary planning for an attack at Pearl Harbor, to protect this move into the "Southern Resource Area" (the Japanese term for the East Indies and Southeast Asia generally), had begun in very early 1941, under the auspices of Admiral Isoroku Yamamoto, then commanding Japan's Combined Fleet. He won assent to formal planning and training for an attack from the Imperial Japanese Navy General Staff only after much contention with Naval Headquarters, including a threat to resign his command. Full-scale planning was underway by early spring 1941, primarily by Captain Minoru Genda. Over the next several months, pilots trained, equipment was adapted, and intelligence gathered. Despite these preparations, the actual order to attack was not issued until after the second of two Imperial Conferences which considered the matter, and final authorization to attack was not given until December 1, after Japanese leaders decided the U.S. was unlikely to accommodate Japanese demands to avoid interference with Japanese expansion. Hostilities between the U.S. and Japan were expected by many observers, including President Roosevelt, who read a decrypted Japanese message and told his assistant Harry Hopkins, "This means war."

Approach and attack

Route followed by the Japanese fleet to Pearl Harbor and back

At 03:42 Hawaiian Time, hours before commanding Admiral Chuichi Nagumo began launching strike aircraft, the minesweeper USS Condor spotted a midget submarine outside the harbor entrance and alerted destroyer USS Ward. Ward was initially unsuccessful in locating the target. Hours later, Ward fired America's first shots in the Pacific theater of WWII when she attacked and sank a midget submarine, perhaps the same one, at 06:37.

Five midget submarines had been assigned to torpedo U.S. ships after the bombing started. None of these returned, and only four have since been found. Of the ten sailors aboard, nine died; the only survivor, Kazuo Sakamaki, was captured, becoming the first Japanese prisoner of war. United States Naval Institute analysis of photographs from the attack, conducted in 1999, indicates one of these mini-subs entered the harbor and successfully fired a torpedo into the USS West Virginia, what may have been the first shot by the attacking Japanese. Her final disposition is unknown.

First wave

The attackers came in two waves. The first wave was detected by U.S. Army radar at 136 nautical miles (252 km), but was misidentified as USAAF bombers from the mainland.

The first attack wave launched north of Oʻahu, commanded by Captain Mitsuo Fuchida. It included:

• 1st Group (targets: battleships and aircraft carriers)
  • 50 Nakajima B5Ns armed with 800 kg (1760 lb) armor piercing bombs, in four sections.
  • 40 B5Ns armed with Type 91 torpedoes, also in four sections.
• 2nd Group — (targets: Ford Island and Wheeler Field)
  • 55 Aichi D3As armed with Template:Auto lb general purpose bombs
• 3rd Group — (targets: aircraft at Ford Island, Hickam Field, Wheeler Field, Barber’s Point, Kaneohe)
  • 45 A6Ms for air control and strafing Each of the aerial waves started with the bombers and ended with the fighters to deter pursuit.

As the first wave approached Oʻahu, an Army SCR-270 radar at Opana Point, near the island's northern tip (a post not yet operational, having been in training mode for months), detected them and called in a warning. Although the operators reported a target echo larger than anything they had ever seen, an untrained officer at the new and only partially activated Intercept Center, Lieutenant Kermit A. Tyler, presumed the scheduled arrival of six B-17 bombers was the source; the direction from which the aircraft were coming was close (only a few degrees separated the two inbound courses); the operators had never seen a formation as large as the U.S. bombers' on radar; and possibly because the operators had only seen the lead element of incoming attack.

Several U.S. aircraft were shot down as the first wave approached land; one at least radioed a somewhat incoherent warning. Other warnings from ships off the harbor entrance were still being processed, or awaiting confirmation, when the planes began bombing and strafing. Nevertheless, it is not clear any warnings would have had much effect even had they been interpreted correctly and much more promptly. For instance, the results the Japanese achieved in the Philippines were essentially the same as at Pearl Harbor, though MacArthur had almost nine hours warning the Japanese had attacked at Pearl (and specific orders to commence operations) before they actually struck his command.

The air portion of the attack on Pearl Harbor began at 7:48 a.m. Hawaiian Time (3:18 a.m. December 8 Japanese Standard Time, as kept by ships of the Kido Butai), with the attack on Kaneohe. A total of 353 Japanese planes in two waves reached Oʻahu. Slow, vulnerable torpedo bombers led the first wave, exploiting the first moments of surprise to attack the most important ships present (the battleships), while dive bombers attacked U.S. air bases across Oʻahu, starting with Hickam Field, the largest, and Wheeler Field, the main U.S. Army Air Corps fighter base. The 171 planes in the second wave attacked the Air Corps' Bellows Field near Kaneohe on the windward side of the island, and Ford Island. The only air opposition came from a handful of P-36 Hawks and P-40 Warhawks.

Men aboard U.S. ships awoke to the sounds of alarms, bombs exploding, and gunfire prompting bleary eyed men into dressing as they ran to General Quarters stations. (The famous message, "Air raid Pearl Harbor. This is not drill.", was sent from the headquarters of Patrol Wing Two, the first senior Hawaiian command to respond.) The defenders were very unprepared. Ammunition lockers were locked, aircraft parked wingtip to wingtip in the open to deter sabotage, guns unmanned (none of the Navy's 5"/38 AA and only a quarter of its machine guns, and only four of 31 Army batteries got in action). Despite this and low alert status, many American military personnel responded effectively during the battle. Ensign Joe Taussig got his ship, USS Nevada, underway from dead cold during the attack. One of the destroyers, USS Aylwin, got underway with only four officers aboard, all Ensigns, none with more than a year's sea duty; she operated at sea for four days before her commanding officer managed to get aboard. Captain Mervyn Bennion, commanding USS West Virginia (Kimmel's flagship), led his men until he was cut down by fragments from a bomb hit to USS Tennessee, moored alongside.

Gallantry was widespread. In all, 14 officers and sailors were awarded the Medal of Honor. A special military award, the Pearl Harbor Commemorative Medal, was later authorized for all military veterans of the attack.

Second wave composition

The second wave consisted of 54 B5Ns, 81 D3As, and 36 A6Ms, commanded by Lieutenant-Commander Shigekazu Shimazaki. This wave and its targets comprised:

• 1st Group — 54 B5Ns armed with Template:Auto lb and Template:Auto lb general purpose bombs
  • 27 B5Ns — aircraft and hangars on Kaneohe, Ford Island, and Barbers Point
  • 27 B5N — hangars and aircraft on Hickam Field
• 2nd Group (targets: aircraft carriers and cruisers)
  • 81 D3As armed with Template:Auto lb general purpose bombs, in four sections
• 3rd Group — (targets: aircraft at Ford Island, Hickham Field, Wheeler Field, Barber’s Point, Kaneohe)
  • 36 A6Ms for defense and strafing

The second wave was divided into three groups. One was tasked to attack Kāneʻohe, the rest Pearl Harbor proper. The separate sections arrived at the attack point almost simultaneously, from several directions.

Ninety minutes after it began, the attack was over. 2,386 Americans died (55 were civilians, most killed by unexploded American anti-aircraft shells landing in civilian areas), a further 1,139 wounded. Eighteen ships were sunk, including five battleships.

Of the American fatalities, nearly half of the total were due to the explosion of USS Arizona's forward magazine after it was hit by a modified 40 cm (16in) shell.

Already damaged by a torpedo and on fire forward, Nevada attempted to exit the harbor. She was targeted by many Japanese bombers as she got under way, sustaining more hits from 250 lb (113 kg) bombs as she was deliberately beached to avoid blocking the harbor entrance.

USS California was hit by two bombs and two torpedoes. The crew might have kept her afloat, but were ordered to abandon ship just as they were raising power for the pumps. Burning oil from Arizona and West Virginia drifted down on her, and probably made the situation look worse than it was. The disarmed target ship USS Utah was holed twice by torpedoes. USS West Virginia was hit by seven torpedoes, the seventh tearing away her rudder. USS Oklahoma was hit by four torpedoes, the last two above her belt armor, which caused her to capsize. USS Maryland was hit by two of the converted 40 cm shells, but neither caused serious damage.

Although the Japanese concentrated on battleships (the largest vessels present), they did not ignore other targets. The light cruiser USS Helena was torpedoed, and the concussion from the blast capsized the neighboring minelayer USS Oglala. Two destroyers in dry dock were destroyed when bombs penetrated their fuel bunkers. The leaking fuel caught fire; flooding the dry dock in an effort to fight fire made the burning oil rise, and so the ships were burned out. The light cruiser USS Raleigh was holed by a torpedo. The light cruiser USS Honolulu was damaged but remained in service. The destroyer USS Cassin capsized, and destroyer USS Downes was heavily damaged. The repair vessel USS Vestal, moored alongside Arizona, was heavily damaged and beached. The seaplane tender USS Curtiss was also damaged. USS Shaw was badly damaged when two bombs penetrated her forward magazine.

Of the 402 American aircraft in Hawaii, 188 were destroyed and 159 damaged, 155 of them on the ground. Almost none were actually ready to take off to defend the base. Of 33 PBYs in Hawaii, 24 were destroyed, and six others damaged beyond repair. (The three on patrol returned undamaged.) Friendly fire brought down several U.S. planes on top of that, including some from an inbound flight from USS Enterprise. Japanese attacks on barracks killed additional personnel.

Fifty-five Japanese airmen and nine submariners were killed in the action. Of Japan's 414 available planes, 29 were lost during the battle (nine in the first attack wave, 20 in the second), with another 74 damaged by antiaircraft fire from the ground.

Possible third wave

Several Japanese junior officers, including Fuchida and the chief architect of the attack, Captain Minoru Genda, urged Nagumo to carry out a third strike in order to destroy as much of Pearl Harbor's fuel storage, maintenance, and dry dock facilities as possible. Some military historians have suggested the destruction of these oil tanks and repair facilities would have crippled the U.S. Pacific Fleet far more seriously than loss of its battleships. If they had been wiped out, "serious [American] operations in the Pacific would have been postponed for more than a year." Nagumo, however, decided to forgo a third attack in favor of withdrawal for several reasons:

• American anti-aircraft performance had improved considerably during the second strike, and two-thirds of Japan's losses were incurred during the second wave. Nagumo felt if he launched a third strike, he would be risking three-quarters of the Combined Fleet's strength to wipe out the remaining targets (which included the facilities) while suffering higher aircraft losses.
• The location of the American carriers remained unknown. In addition, the Admiral was concerned his force was now within range of American land-based bombers. Nagumo was uncertain whether the U.S. had enough surviving planes remaining on Hawaii to launch an attack against Japan's carriers.
• A third wave attack would have required substantial preparation and turn-around time, and would have meant returning planes would have faced night landings. At the time, no Navy had developed night carrier techniques, so this was a substantial risk.
• The task force's fuel situation did not permit him to remain in waters north of Pearl Harbor much longer since he was at the very limits of logistical support. To do so risked running unacceptably low on fuel, perhaps even having to abandon destroyers en route home.
• He believed the second strike had essentially satisfied the main objective of his mission — the neutralization of the Pacific Fleet — and did not wish to risk further losses.

At a conference aboard Yamato the following morning, Yamamoto initially supported Nagumo's decision to withdraw. In retrospect, however, Nagumo's decision to spare the vital dockyards, maintenance shops, and oil depots meant the U.S. could respond relatively quickly to Japanese activities in the Pacific. Yamamoto later regretted Nagumo's decision and categorically stated it had been a great mistake not to order a third strike.

Though the attack was notable for its large-scale destruction, the damage was not significant in terms of American fuel storage, maintenance and intelligence capabilities. Had Japan destroyed the American carriers, the U.S. would have sustained significant damage to the Pacific Fleet's ability to conduct offensive operations for a year or so (given no diversions from the Atlantic Fleet). As it was, the elimination of the battleships left the U.S. Navy with no choice but to place its faith in aircraft carriers and submarines — the very weapons with which the U.S. Navy halted and eventually reversed the Japanese advance. A major flaw of Japanese strategic thinking was a belief the ultimate Pacific battle would be between battleships of both sides, in keeping with the doctrine of Captain Alfred Mahan. As a result, Yamamoto (and his successors) hoarded battleships for a "decisive battle" that never happened.

Ultimately, targets not on Genda's list, such as the Submarine Base and the old Headquarters Building, proved more important than any battleship. It was submarines that immobilized IJN's heavy ships and brought Japan's economy to a standstill by crippling transportation of oil and raw materials. And in the basement of the old Administration Building was the cryptanalytic unit, HYPO, which contributed significantly to the Midway ambush and the Submarine Force's success.
