Operation Redwing : ウィキペディア英語版 | Operation Redwing
Operation Redwing was a United States series of 17 nuclear test detonations from May to July 1956. They were conducted at Bikini and Enewetak atolls. The entire operation followed ''Project 56'' and preceded ''Project 57''. The primary intention was to test new, second-generation thermonuclear devices. Also tested were fission devices intended to be used as primaries for thermonuclear weapons, and small tactical weapons for air defense. ''Redwing'' demonstrated the first US airdrop of a deliverable hydrogen bomb - test ''Cherokee''. Because the yields for many tests at ''Operation Castle'' in 1954 were dramatically higher than predictions, ''Redwing'' was conducted using an "energy budget" - there were limits to the total amount of energy released, and the amount of fission yield was also strictly controlled. Fission, primarily "fast" fission of the natural uranium tamper surrounding the fusion capsule, greatly increases the yield of thermonuclear devices, and contributes the vast majority of the fallout - fusion being a relatively clean reaction. All shots were named after various Native American tribes.
