It is estimated that all over the world, in the twentieth century alone, there were 130 million plus war casualties. However, these wars did lead to mile stones in technology, with countries becoming eager to protect themselves from threats all over the world new military technology were popping up all over the world. Often the new technology could be used in civilian life. The most significant innovations Canada played a role in were the Radar and the Atomic Bomb. A major Canadian innovation towards military technology was the Radar. With the battle of the Atlantic raging on and the German Luftwaffe launching deadly aerial attacks, Britain needed a way of detecting the Germans before it was too late. With an incapable radar like system already in existence , Britain, with huge support from the National Research Council of Canada, went to work and built a modern version to meet Britain 's requirements and expectations. As experimental designs proved successful, large scale projects were launched all over Britain, with as many as fifty radar installations spread out across the East and West coasts of Great Britain . These radar installations played a major role in the Royal Air forces victory in the Battle of Britain. Because of the success the Radar
