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 receivi... ... middle of paper ... ...ne. Web. 3 Apr. 2012. . Hackmann, Willem Dirk. “SONAR.” Encyclopedia of World War II. Vol. 2.

Weapons and Artillery of World War II The result of World War II was affected by many different factors. One major factor which affected the war was the weapons and artillery used during the war. Since the beginnings of time, weapons have always been around. From swords and knives to nuclear weapons and missiles, weapons have evolved greatly over the years.

At 5:30 AM July 16th 1945, the nuclear age had started. The world’s first atomic bomb was detonated. On August 6th 1942 at 8:15 AM, an American B-29 bomber, the Enola Gay, dropped a perfected atomic bomb created by the Americans, over the city of Hiroshima hoping to end the war. Thousands of people died in the two cities in Japan. They were Hiroshima and Nagasaki “the Manhattan Project”. The research and development project that produced these atomic bombs during this time was known as “the Manhattan Project”.
The development and usage of the first atomic bombs has caused a change in military, political, and public functionality of the world today. The bombings of Hiroshima and Nagasaki revolutionized warfare by killing large masses of civilian population with a single strike. The bombs’ effects from the blast, extreme heat, and radiation left an estimated 140,000 people dead. The bombs created a temporary resolution that lead to another conflict. The Cold War was a political standoff between the Soviet Union and the United States that again created a new worldwide nuclear threat. The destructive potential of nuclear weapons had created a global sweep of fear as to what might happen if these terrible forces where unleashed again. The technology involved in building the first atomic bombs has grown into the creation of nuclear weapons that are potentially 40 times more powerful than the original bombs used. However, a military change in strategy has came to promote nuclear disarmament and prevent the usage of nuclear weapons. The technology of building the atomic bomb has spurred some useful innovations that can be applied through the use of nuclear power. The fear of a potential nuclear attack had been heightened by the media and its release of movies impacting on public opinion and fear of nuclear devastation. The lives lost after the detonation of the atomic bombs have become warning signs that changed global thinking and caused preventative actions.

The next method that was discussed in the article was side-scan sonar systems. This method uses an object that is shaped like a torpedo; this is then towed behind the ship at a depth that is around 10 percent of the width. The side-scan method uses two fan shaped beams, as the beams reflect off of the sea floor there is a scan line that when plotted with the other scan lines an image is created. This method also has it’s downsides as well radiometric artifacts are harder to distinguish than geometric artifacts, this can lead to some artifacts not being noticed or being confused with natural objects such as rocks.
