Technology of WWII

By: John & Felix

objectives by the end of this presentation you should be able to
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
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
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  • WWII was when battle ships were at their prim use, before becoming outdated by aircraft carriers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

submarines
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
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 & 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
secret codes
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
Medical Advances
  • Penicillin
    • Antibiotic used to treat infections
    • Discovered in 1929 by Alexander Fleming
    • Recovery rates increased dramatically due to penicillin
atomic bombs
Atomic Bombs
  • Devolped by the U.S. via the “Manhattan Project”
  • Largest explosives ever recorder
    • Ability to destroy entire cities
  • Large EMP generated
recap
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
