Atomic Age

By: Brandon Fry



The Bombs

gun barrel
Gun Barrel
  • Detonated by shooting one piece of sub-critical material into another, creating a exponentially growing nuclear chain reaction.
  • The resulting explosion is fueled by a mass of fissile material.
  • Explosion energy can be in the range of 1 – 500,000 tons of TNT
implosion design
Implosion Design
  • Created by a fast outer “core” explosive pushing and compressing on all sides of a subcritical mass.
  • Inner core made of supercritical mass and fuel.
  • Considered more

sophisticated than the gun

barrel method.

  • The Davy Crockett was a portable nuke.
  • The maximum range was three miles.
  • Never fully used in combat due to the fact that the gun could not fire far enough without being in the radius of the explosion

See it in action!

  • The B-29 bomber was used for the first bombs, “Fat Man” and “Little Boy”
  • The crew first used pumpkins for practice
  • First execution for civilians from an espionage charge.
  • Provided many top secret designs including a fuse design that shot down a U-2 Spy plane.
  • Had two children who were orphaned and no relatives took them in.

Morris Cohen
  • Also known in London as Peter Kroger.
  • Married into the spy ring with wife, Lona Cohen, who worked for Soviet case officers, including AnatoliYatskov.
  • This spy ring was more effective than the Rosenburg ring.

FBI File


  • The first nuclear test took place on 5:30 a.m. on Monday, July 16, 1945.
  • “Little Boy” was never tested because the design was trusted to work and there was not enough uranium to make another bomb.
