In WWI submarines were mostly used to protect cargo and gather merchant ships, but in WWII the submarines had gotten sonar and had become a prime weapon. The Battle of the Atlantic was crucial to who could win the war, if the Axis won, they won the war, if the Allies won, then they actually would have a fighting chance. U-Boats were Germany’s prime weapon, the torpedo was what took out the allies ships without anyone seeing it coming. That all changed when the Allies had started using ASW (Anti-Submarine Warfare) which was critical to the success of the allies, with the ASW the allies were able to destroy 73% of Germany’s U-boats. The US had a convoy system which basically made life harder for the Axis. At that moment in time the tides had officially turned in the …show more content…
They had a strong convoy system that was heavily guarded by warships, the convoy’s held about 20-30,000 troops and went about 13 knots, that like I previously mentioned was responsible for the defeat of U-boats. Along with convoy systems, an Aircraft called the Catalina also held great power which was used by the allies to win a lot of tough battles. The Catalina had machine guns around the whole aircraft, but were mostly used in the pacific to bomb Japanese bases. A significant tool used to take down the axis was people, not just anyone but geniuses that could decode German naval codes. An example is the Battle of Midway and even though that’s in the pacific it shows how the Allies had gained the upper hand after years of wondering when the axis is gonna win. The Enigma machine which was actually used in the Battle of the Atlantic had fundamentally changed the game for the Allies leading to multiple victories, with the help of the Enigma Machine British destroyers had captured a German U-boat called U-110 in Iceland. Along with ASW there was AAR (Advanced Airborne Radar) which could also scope out Subs at night at a 40 miles radius. These strategic tactics had fundamentally changed the outlook of
