1st Hydrogen Bomb Test by USA (Operation Ivy - Mike) 1952

Ivy MikeTest: Mike
Time: 19:14:59.4 31 October 1952 (GMT)
07:14:59.4 1 November 1952 (local)
Location: Elugelab ("Flora") Island, Enewetak Atoll
Test Height and Type: Surface burst
Yield: 10.4 Mt

The mushroom cloud climbed to 57,000 feet in only 90 seconds, entering the stratosphere. One minute later it reached 108,000 feet, eventually stabilizing at a ceiling of 120,000 feet. Half an hour after the test the mushroom stretched 60 miles across, with the base of the mushroom head joining the stem at 45,000 feet.

The device detonated in the Mike ("m" for "megaton") test, called the Sausage, was the first "true" H-Bomb ever tested, that is - the first thermonuclear device built upon the Teller-Ulam principles of staged radiation implosion. The device was designed by the Panda Committee directed by J. Carson Mark at Los Alamos (Teller declined to play a role in its development).

The 10.4 megaton device was a two stage device using a TX-5 fission bomb as the primary stage, and a secondary stage consisting of liquid deuterium fusion fuel stored in a cylindrical Dewar (thermos) flask. Running down the center of the Dewar was a plutonium "spark plug" rod to ignite the fusion reaction. The Dewar was surrounded by a natural uranium pusher/tamper weighing more than 5 metric tons. The entire assembly was housed in an enormous steel casing, 80 inches wide and 244 inches long, with walls ~10-12 inches thick, the largest single forging made up to that time. The inside surface of the casing was lined with sheets of lead and polyethylene to form the radiation channel that conducted heat from the primary to the secondary. The entire device weighed 82 tons.

The enormous explosion was the 4th largest device ever tested by the U.S. 77% (8 megatons) of the yield was due to fast fission of the natural uranium pusher/tamper, with remainder (2.4 megatons) coming directly from fusion of the deuterium fuel. The island the test device was installed on, Elugelab (code named Flora), was entirely destroyed. The resulting crater was 6240 ft across and 164 ft deep. High levels of radiation blanketed much of the atoll following the test.

hey guys

want to see me make an island disappear?

[poposisa]

"USA, Fucking up since 1952"

[mrcuntington]

@guitarguy1067 I'd rather see a group of Arab nations north of Africa disappear

wiping an island of the map i swear to god the human race is so powerful and dangerous now even to itself

Robert, what have you done?

@lallen18: Oh, come. An H bomb gives off radiation, most particularly neutrons and tritium. It's relatively clean compared to ab equivalent yield of a fission device, but it still has radiation. A fission device's worst fallout problem is in the fission products, the pieces of atoms left over when uranium splits. Fusion doesn't have an equivalent to that, but fusion weapons do need a fission "primary" to start their burn.

@tamenga88: The particular island the shed was on, Eulegulab, did indeed disappear, as did another island, Irioj, in Bikini Atoll.

@skubischta There was a device called the E(mergency)C(apability)-16 "Jughead" which was a liquid deuterium fueled physics package in a deliverable form in late 1953. The Shrimp device using enriched isotope six lithium deuteride fusion fuel. The success of the Shrimp package made the EC-16 obsolete.

@WhiteSunGroupoff lol usa is a weak country thats why every country sucks our dick and we dont even pay china back and they dont say shit because they know better than to fuck with a country with the most advanced military in the world.. but yea go on with ur dumb comment

[WhiteSunGroupoff]

@rlax106 USA is a weak country, stop being so patriotic.
