Technology of WWII By: John & Felix
ObjectivesBy the end of this presentation you should be able to: • Compare and contrast the differences in ground warfare in WWI and WWII • Describe submarines and battleships • Describe how technology influenced the war in the air and sea(RADAR/SONAR) • State the significance of secret codes used during WWII (Enigma and decoding)
Ground Warfare • The infantry was a very strong power because of their new weapons like rocket launchers or improved machine guns • Infantry was replaced more and more by airplanes and tanks • Germany had the best tanks • Big role in the Blitzkrieg
Warfare technology in the seas • During WWII great changes in naval warfare took place • Rapid growth in use and capability of subs • Anti-submarine technologies quickly employed. (SONAR) • Aircraft carrier ships were well used by the United States, British, and Japanese navies. • Aircraft carriers became the backbone/premier ships in navies
Battleships • WWII was when battle ships were at their prim use, before becoming outdated by aircraft carriers • Battleships could fire shells over 32 KM • Next round would be fired before the pervious one landed http://www.youtube.com/watch?v=_8aH-M3PzM0 u.s navy vintage fire control computers
Submarines • German submarines (U-Boats or Unterseeboot (undersea boat)) became increasingly capable • Often traveled in “wolf packs” after the advent of ASDIC (SONAR) and RADAR • Major component in the battle for the Atlantic • Very space efficient, (cramped) • Towards the end of the war the life expectancy of a U-boat crewman was about 60 days

Planes & Rockets Increased technology of planes First jetfighters were produced by the Germans Me 262 Germany developed a propulsion rocket with a very long range
RADAR & SONAR • RADAR stands for RAdio Detection and Ranging • SONAR stands for SOund Navigation And Ranging • First used by Allies • RADAR was a major cause in the British victory in the Battle of Britain • SONAR was mainly used against German submarines • RADAR is better in air compared to SONAR SONAR is better in water compared to RADAR
SONAR travels in compression waves while RADAR travels in Transverse waves
Secret Codes • The Enigma was found by the Germans and is a machine that encrypts messages • A similar way to communicate was the lorenzchiper • The colossus was a computer that was used to decipher the German codes Cipher that was used for decoding from the German Enigma machines
Medical Advances • Penicillin • Antibiotic used to treat infections • Discovered in 1929 by Alexander Fleming • Recovery rates increased dramatically due to penicillin
Atomic Bombs • Devolped by the U.S. via the “Manhattan Project” • Largest explosives ever recorder • Ability to destroy entire cities • Large EMP generated
Recap • Great changes in technology took place during WWII, which ultimately reshaped warfare • During WWII technology advanced very quickly, and was driven by warfare • Many spin off technologies that were originally devolved for warfare found other uses
