World War II Inventions

Between 1939 and 1945, WWII brought many innovations and inventions to the world. New countries, organizations, weapons, and technological advances were produced. The three that had the maximum impact on the war were the invention of the radar, aircraft, and the atomic bomb because of their effective uses.

The first practical radar system was invented in 1935 by the Scottish physicist

Robert Alexander Watson, but it was later developed by the English during WWII.

The radar was used to determine where a distant object was, how big it was, what shape it had, how fast it was moving and in which direction it was going. When Germany sent 2,000 planes every night for two solid months to try to gain control of the skies by destroying Britain’s nuclear air force, British pilots accurately plotted the flight paths of German planes , even in the darkness, due to the radar. The radar is important because it prevents planes to crash into each other and it is used today to manage traffic control, to detect missiles, and to detect weather conditions.

Aircraft impacted WWII in a major way, it was the main weapon. Fighter aircraft of the second world war featured all the innovations of the 1930s. Piston-engined fighters continued to be refined and developed with increasing performance and capabilities. Planes were used in WWII because they were fast and because they could attack on land and sea. Planes impacted the history of the world because they were used to attack Britain by the Germans, they were used on the attack of pearl harbor and they were used to drop the atomic bomb on Hiroshima and Nagasaki. Planes played a significant role because they were the major attacking utensil used in this war.

Unlike aircraft, the atomic bomb wasn’t used so much but it created more damage than planes and it ended war. The atomic bomb’s explosive power originates when the nucleus of a heavy atom is split. The uranium in an atomic bomb can release one million times as much energy as TNT. The Fission bomb impacted the world because it exterminated Hiroshima and Nagasaki, killing about 140.000 thousand people and injuring thousands. These bombs created Thermal radiation, which results from the extremely high temperatures created by an atomic explosion, causes serious burns on exposed parts of the body and may ignite fires over a wide radius.
