jliat: "noise" cdr ep Contains digitally remastered archive recordings of the following events: From the Bikini Series nuclear tests, [1] Able 22:00:34 30 June 1946 (GMT) Bikini Atoll lagoon, Marshall Islands, [2] Bravo 18:45:00 28 February 1954 (GMT) Artificial island on reef 2950 ft off Namu (Charlie) Island, Bikini Atoll, [3] Cherokee 17:51 20 May 1956 Off Namu (Charlie) Island, Bikini Atoll Test Site, [4] Fir 17:50.00.1 11 May 1958 (GMT) Bikini Barge. The first test, Able was History's fourth atomic explosion. A standard Fat Man type Mk 3A fission bomb, dropped by B-29 "Dave's Dream", was used in test. The bomb fell 980 ft short and 1870 ft left of target, perhaps due to a collapsed tail fin. The USS Gilliam was sunk, and four other vessels were either sunk or severly damaged. The misplaced bomb resulted in a government investigation of the flight crew. The Crossroads Series tests were the first nuclear explosions since World War II, and the first nuclear weapon tests since Trinity. These were the first "weapons effects" tests ever conducted - tests designed specifically to study how nuclear explosions affect other things - rather than tests of the behavior of a weapon design (as was Trinity). The purpose of the tests was to examine the effects of nuclear explosions on naval vessels, planes, and animals. A fleet of 71 surplus and captured ships anchored in the Bikini Atoll lagoon in the Marshall Islands were used as targets. This fleet included a number of famous Allied and Axis vessels such as the aircraft carrier USS Saratoga, the battleships USS Nevada, Pennsylvania, Arkansas, and New York; the German cruiser Prinz Eugen and Japanese battleshp Nagato. The weapons used were Mk 3A ("Model 1561") Fat Man-type atomic bombs, essentially unmodified from the wartime designs. Incidently, archival film footage derived from the same sources was used in Bruce Conner's 1976 film "Crossroads." The Shrimp device tested in Bravo was a 15 Mt two stage thermonuclear surface burst. This was the first "dry" or solid fuel (lithium deuteride fueled) H-Bomb tested by the U.S., and the first solid fuel Teller-Ulam device ever tested. It was the largest bomb ever tested by the U.S. although this was by accident. The yield of Bravo dramatically exceeded predictions, being about 2.5 times higher than the best guess and almost double the estimated maximum possible yield (6 Mt predicted, estimated yield range 4-8 Mt). The Bravo crater in the atoll reef had a diameter of 6510 ft, with a depth of 250 ft. Within one minute the mushroom cloud had reached 50,000 feet (15 km), breaking 100,000 feet (30 km) two minutes later. The cloud top rose and peaked at 130,000 feet (almost 40 km) after only six minutes. Eight minutes after the test the cloud had reached its full dimensions with a diameter of 100 km, a stem 7 km thick, and a cloud bottom rising above 55,000 feet (16.5 km). And these are just the first two tests. Extensive notes contained on plastic inserts backed with black liner. Black cdr. Initial edition of 50. File under: scary as Hell.
