Attack on Pearl Harbor Palmer, John and Ray
Planning of the Attack • Japanese Combined Fleet, Admiral Isoroku Yamamoto took command of this attack. • His staff found that the assault was feasible, given the greater capabilities of newer aircraft types, modifications to aerial torpedoes because of the shallow depths of the harbor, a high level of communications security and a reasonable level of good luck. • All six of Japan's first-line aircraft carriers, were assigned to the mission. With over 420 embarked planes, these ships constituted by far the most powerful carrier task force ever assembled. • The force also included fast battleships, cruisers and destroyers, with tankers to fuel the ships during their passage across the Pacific. • An Advance Expeditionary Force of large submarines, five of them carrying midget submarines, was sent to scout around Hawaii, dispatch the midgets into Pearl Harbor to attack ships there, and torpedo American warships that might escape to sea.
Morning of the Attack • Before dawn on the 7th of December, undiscovered and with diplomatic prospects firmly at an end, the Pearl Harbor Striking Force was less than three-hundred miles north of Pearl Harbor. • A first attack wave of over 180 aircraft, including torpedo planes, high-level bombers, dive bombers and fighters, was launched in the darkness and flew off to the south. • When first group had taken off, a second attack wave of similar size, but with more dive bombers and no torpedo planes. Near Oahu's southern shore, the five midget submarines had already cast loose to enter the harbor
The Attack • When the first Japanese attack wave arrived over Pearl Harbor seven of their primary targets, the U.S. battleships, were sitting along "Battleship Row", on the eastern side of Ford Island. Another battleship was in dry-dock in the nearby Navy Yard. Other piers which the Japanese believed might include battleships, or the equally important aircraft carriers. • The Japanese initially hit airfields, including that on Ford Island. Dive bombers attacked there at about 7:55 AM, destroying many aircraft, among them PBY patrol planes at the island's southern tip.
“Battleship Row” • Pier F-2, the southernmost, which usually hosted an aircraft carrier, was empty. Northeastward, Battle Force flagship California was next, Pier at F-3. Then came two pairs, moored side by side: Maryland with Oklahoma outboard, and Tennessee with West Virginia outboard. Astern of Tennessee lay Arizona, which had the repair ship Vestal alongside. Last in line was USS Nevada, by herself at Pier F-8. • Twenty-four of the forty Japanese torpedo planes were assigned to attack "Battleship Row", and five more diverted to that side of Ford Island when they found no battleships in their intended target areas. Of these planes' twenty-nine Type 91 aerial torpedoes (each with a warhead of some 450 pounds of high explosive), up to twenty-one found their targets: two hit California, one exploded against Nevada and as many as nine each struck Oklahoma and West Virginia. The latter two ships sank within minutes of receiving this torpedo damage.
“Battleship Row” Continued • Horizontal bombers, armed with heavy armor-piercing bombs, arrived just as the last torpedo planes finished their attacks, and other horizontal and dive bombers came in later. • Together, these planes scored many hits or damaging near-misses on the "Battleship Row" ships: two on California, Maryland and Tennessee; a few on West Virginia. • Most spectacular of the bombers' victims was Arizona, which was struck many times. One bomb penetrated to the vicinity of her forward magazines, which detonated with a massive blast, immediately sinking the ship. Before The Attack After The Attack
The Aftermath • On 8 December, President Franklin Delano Roosevelt addressed the Congress to ask for a declaration of war against Japan. • Referring to December 7th, 1941, as a "day that shall live in infamy", he gave the Pearl Harbor attack its most famous and enduring title. • Within a few days, Germany and Italy had declared war on the United States. Even before the President's speech, Americans were flooding recruiting offices to try to join the Armed Forces. • The Japanese had put out of action all seven battleships present on "Battleship Row". Two, Maryland and Tennessee, were repaired in a matter of weeks, as was the Pennsylvania. However, three were under repair for a year or more. • Oklahoma and Arizona would never return to service. Even with the addition of three more battleships brought around from the Atlantic, the Japanese battle line was assured of absolute superiority in the critical months to come.
