Operation Greenhouse, Nuclear tests series at Enewetak Atoll, US.
Operation Greenhouse was a series of four nuclear tests conducted in 1951 at Enewetak Atoll in the Marshall Islands. The tests, codenamed Dog, Easy, George, and Item, took place across different islands of the atoll to study various aspects of nuclear weapons development.
This test series marked a crucial transition in nuclear weapons development, particularly with the George test, which demonstrated the world's first thermonuclear reaction. The success of these tests led to new designs and technologies that shaped the future of nuclear weapons development.
Military officials and guests observed the Dog nuclear detonation from Adirondack chairs while wearing protective goggles, demonstrating the period's approach to nuclear testing.
The atoll served as a testing ground with specially built structures on various islands to measure explosion effects. Visitors should know that the area remains largely inaccessible today due to radiation and contamination concerns.
The Item test was the first to employ fusion boosting technology, which increased the efficiency of the fission core. This innovation doubled the explosive yield and revolutionized weapon design for decades to come.
