Presentation Transcript

  1. Technology and Homeland Security in WWII By: Orlin Zlatarski, Max Utner, and Max Schock

  2. Advances in technology

  3. Blitzkrieg (lightning war) • Highly-mechanized • Penetration + Overpowering • Ideas from Germans, British, and French

  4. Radar and Sonar • Originally called RDF (radio direction finder) • Developed by British • Enabled a decisive British victory in the Battle of Britain (1940)

  5. Rocket Propulsion • Enabled first long ranged missiles • Randomly fell after certain number of rotations of propeller • By end of WWII, ± 1.5 km off target • Amazingly accurate • Computer programmed (4 bits program) • Called Doodlebugs by British because of their buzz sound

  6. Jet Planes • Germans developed it first • Came late in the war (1944 – mass production) • Not perfected, hardly strategically advantageous

  7. Norden Bombsight • Developed by the US (little prior to WWII) • German spy Herbert Lang leaked information to German Luftwaffe officials • Used widely by German Luftwaffe by 1942

  8. Proximity Fuze • Developed by: Johns Hopkins Applied Physics Lab, US • Enabled detonation of explosive device after it reached a predetermined radius • Very effective • Substantial influence on the outcome of WWII due to its accuracy and effectively • Used in Battle of the Bulge against enemy personnel, and against Kamikazis

  9. Atomic Bomb • Little Boy (Hiroshima) and Fat Man (Nagasaki) • Caused Japanese to exit from war • Major implications in following Cold War • Developed by the American: Robert Oppenheimer under direction of Leslie Groves
