Technology During World War 2 Essay

2356 words - 9 pages

In the war between countries, technology has played a huge part in the outcome; this is especially evident during the time of World War II. Technology in warfare consisted of weapons, vehicles, aircrafts, and chemical reactants. Technology during World War I was lacking and countries knew when World War II began that in order for them to be victorious they must have the most technologically advanced weapons and other devices or systems that would benefit the nation. The Allies were victorious in WW2 because they made better use of the available technologies than the Germans, advancing in communication/detection systems such as sonar and the radio, as well as, weapons including the atomic bomb, and bomber aircrafts.
One communication system that the Allies used more effectively than the Axis was the SONAR system. Sonar was an acronym that originally stood for Sound Navigation and Ranging. Sonar works by using sound propagation, most often underwater, to navigate and communicate with or detect objects around them (Overy). This was crucial to the war effort due to the fact that the Allies were able to detect and alert people where a boat was and which direction it was heading in. This was vital because thanks to SONAR the Axis were able to sense threats and notify There were two different types of sonar systems that were used during World War II: active sonar and passive sonar. Active SONAR systems used an acoustic projector to generate a sound wave into the water, which was reflected back by a target. The reflected waves were detected by a SONAR receiver, which analyzed the signal to determine the range, bearing, and relative motion of the target. " (Hackmann). Different than active SONAR, passive SONAR only had receiving sensors, which detected the noise that another object made. The waveforms that were received by the passive SONAR system were then analyzed for the direction and distance that the noise came from (Hackmann). SONAR helped the Allies win the war due to its ability to detect objects above or around them, which allowed for the Allies to be more prepared for battle. SONAR was not the only system used during this time to detect objects in the area, but also RADAR.
RADAR complimented SONAR as another communication system in which the Allies used more efficiently to be victorious. “Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio waves or microwaves, which bounce off any object in their path. The object returns a tiny part of the wave's energy to a dish or antenna, which is usually located at the same site as the transmitter” (Overy). RADAR was an effective system that countries used to find out general information of an object which was helpful during warfare because if there...
