# FIRST H-BOMB THERMONUCLEAR HYDROGEN BOMB TEST FILM IVY MIKE 42244c

Made for the home market by World in Color Productions, this silent color newsreel shows the first full scale hydrogen bomb test at Enewetak, known as Ivy Mike. Various views of the test are seen, including aerial footage of the blasts. Ivy Mike was the codename given to the first test of a full-scale thermonuclear device, in which part of the explosive yield comes from nuclear fusion. It was detonated on November 1, 1952 by the United States on Enewetak, an atoll in the Pacific Ocean, as part of Operation Ivy. The device was the first full test of the Teller-Ulam design, a staged fusion bomb, and was the first successful test of a hydrogen bomb. Due to its physical size and fusion fuel type (cryogenic liquid deuterium), the Mike device was not suitable for use as a weapon; it was intended as an extremely conservative proof of concept experiment to validate the concepts used for multi-megaton detonations. A simplified and lightened bomb version (the EC-16) was prepared, and scheduled to be tested in operation Castle Yankee, as a backup in case the non-cryogenic "Shrimp" fusion device (tested in Castle Bravo) failed to work; that test was cancelled when the Bravo device was tested successfully, making the cryogenic designs obsolete. The test was carried out at 07:15 A.M local time on November 1, 1952 (19:15 October 31 GMT). It produced a yield estimated in the range of 10.4–12 megatons of TNT. However, 77% of the final yield came from fast fission of the uranium tamper,…
