Operation Redwing, Nuclear test series at Enewetak and Bikini Atolls, United States.
Operation Redwing was a series of nuclear tests conducted at Enewetak and Bikini Atolls between May and July 1956. The tests included 17 detonations using different methods such as barge-mounted devices, surface setups, air drops, and tower placements.
The test series began in 1956 as part of Cold War arms development and aimed to prove second-generation thermonuclear weapon designs. The combined yield of 20.82 megatons demonstrated advances in weapons technology during that era.
The nuclear tests received names from Native American tribes, including Cherokee, Zuni, Dakota, and Navajo, reflecting military naming conventions.
The tests took place at two atoll locations selected specifically for detonations to enable measurement and control. An energy budget system was implemented to limit explosive force and minimize atmospheric radiation from the blast.
During the Cherokee test, a navigation error caused the airdropped weapon to land four miles from its target, disrupting planned data collection. This mishap led to procedure adjustments for subsequent detonations.
