Gun Barrel Detonated by shooting one piece of subcritical material into another, creating a exponentially growing nuclear chain reaction. Detonated by shooting one piece of subcritical material into another, creating a exponentially growing nuclear chain reaction. The resulting explosion is fueled by a mass of fissile material. 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 Explosion energy can be in the range of 1 – 500,000 tons of TNT

Implosion Design Created by a fast outer “core” explosive pushing and compressing on all sides of a subcritical mass. 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. Inner core made of supercritical mass and fuel. Considered more Considered more sophisticated than the gun barrel method.

Deployment

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!

Deployment The B-29 bomber was used for the first bombs, “Fat Man” and “Little Boy” The crew first used pumpkins for practice

(The ones that don’t glow in the dark) Atomic Spies (The ones that don’t glow in the dark)

Rosenburgs 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. The trial file

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 Anatoli Yatskov. This spy ring was more effective than the Rosenburg ring. FBI File

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