Aircraft Carrier Development World War II brought many technological advances that changed the way warfare was conducted; however, the invention of the aircraft carrier was the most important advancement that actually began at the end of World War I. After the plane was invented, it was soon used for reconnaissance and then pilots eventually dropped bombs from them and eventually fired weapons from them. against other aircraft and ground troops. After improvements such as more powerful engines, lighter materials, and weapons synchronized with propeller speed, came the new method of transporting aircraft and using their firepower abroad by aircraft carrier. Aircraft carriers transformed the methods used to fight battles during World War II because Army and Marine infantrymen had air support during raids on Axis countries and islands that would have been unavailable due to the fuel limitations of the planes. A key demonstration of the use of aircraft carriers in World War II was the bombing of Pearl Harbor on December 7, 1941. The Imperial Japanese Navy launched several waves of torpedo bombers and dive bombers to also attack the cruisers, destroyers, and battleships at Pearl Harbor . such as fighter planes and hangars to crush US naval power. The ultimate goal of Pearl Harbor; however, it was to destroy the US aircraft carriers because Japan knew the tactical advantages of having aircraft carriers and the US industrial capacity to produce more warships and weapons. “Since Pearl…Japan's industrial base has not been able to compensate for the losses suffered by its navy.” The aircraft carrier was the most important technological advancement during the world… the usefulness of the aircraft carrier was the Doolittle Raid during World War II. Several B 25 bombers were modified to take off from the USS Hornet and bomb Japan in response to Pearl Harbor, while fighters had been used on aircraft carriers during World War II. Although these inventions were a valuable contribution during World War II, the B 29 bomber that dropped the atomic bomb would not have ended World War II so quickly if the carrier had not been able to support the war effort during the Pacific Theater . The jet fighter ultimately opened up new fields of exploration for the military, but it was invented at the very end of World War II and did not have enough time to establish itself as a venerable fighting machine during World War II. The aircraft carrier had ample time for experimentation and testing, so it was ready for combat operations during World War II.
