WWII officially began in September 1939 when the Nazis invaded Poland. When this happened it got Poland’s allies Britain and France involved. The reason Britain and France had to get involved is because they had an allie contract with Poland that stated one must protect another. While this was happening the U.S didn’t have any allies involved with WWII, so the United States stayed neutral in the world war. At about 7:55am (local time) on December 7th, 1941 the first Japanese dive bomber plane arrived at Pearl Harbor. The commander in chief Yamamoto Isoroku was the one who planned the attack on Pearl Harbor. The Japanese aircraft carrier commander was Admiral Nagumo Chuichi, who had sailed eastward undetected by any U.S. reconnaissance until he was 275 miles north of Hawaii. On Sunday, December 7, 1941, roughly 360 aircrafts, made up of dive-bombers, torpedo bombers, and a few fighters, were launched in two waves to attack Pearl Harbor. Pearl Harbor was holding 70 U.S. fighting ships, 24 auxiliaries, and about 300 planes. The Americans were taken by surprise, and all eight of the battleships in the harbor were hit (six of which were eventually repaired and returned to service), three cruisers, three destroyers, a minelayer, and some ships were damaged. More than 180 aircrafts were destroyed and others damaged (most while inactive), and more than 2,330 U.S. troops were killed and over 1,140 wounded. The Japanese losses were very minimal compared to the United States losses. The Japanese plan had one huge flaw though; the Pacific Fleet had three aircraft carriers that were at sea at the time of the attack and escaped from being damaged by the bombing. These three ships eventually became the beginning of the United States naval defense in the Pacific. Pearl Harbor’s shore installations and oil-storage facilities also escaped any damage from the bombing. On December 8th the U.S congress voted on whether to join WWII or stay neutral. After the voting we declared war on Japan with only one person opposing. When the Japanese attacked the same day, Formosa-based Japanese bombers hit Clark and Iba airfields in the Philippines. The bombing destroyed more than half of the U.S army’s far east aircraft. Two days later, further raids destroyed not only more U.S fighters but also part of the cavite naval yard which is also in the Philippines. Part of the U.S Asiatic fleet, however, had already gone south in November, and the major ships and bomber aircraft that didn’t get destroyed had lack of fighter protection and were withdrawn in the next couple nights to bases in Java and Australia.This affected aerospace history because nowadays they don’t keep all of our planes and boats in one area like they used to before to prevent the excessive loss from happening again. It also launched the fight response in Americans which focused all efforts to the war that they declared on Japan. All efforts to the war meaning that they day and night were building bigger and better aircrafts and machinery to win the war they had started. According to the science section of DailyMail, the U.S has specialized “graveyards,” also known as bone yards that are used to salvage unusable retired planes. These planes are stored in desert dry conditions to prevent rusting and to hopefully be able to fix them up to fly once again or to spare parts from them which can be used to better the new aircrafts being built today.Overall, through the events of the Pearl Harbor attack on December 8th, the U.S. has bettered their naval and airforce strategies and improved both aircraft and ship technologies.
