Submarines played a huge role in World War I. They were very hard to locate and sink which made them valuable when other nations were attacking. Originally submarines were intended as a defense system because they were not very fast. They were powered by a Diesel engine with a top speed of 17 kilometers per hour. However, submarines could take out any size ship, which was why nations soon began to use them as weapons, not just a defense system. There were also many inventions that helped improve submarines such as circling and magnetic torpedoes, and the gyro compass allowing for more accurate navigation. These upgrades and abilities that the submarines had made them extremely dominate in the war. There were actually only 29 submarines ready and manufactured when the war started but over the years that number increased dramatically. In fact they were so dominant that between 1914 and 1918, nations deployed nearly 10,000 ships, thousands of planes, and more than 100,000 mines to slow them down. This is role that submarines played in World War I and why they were so important. Links:
