Y-12

D.1943-12

Pendant la Seconde Guerre mondiale, le RDX, un puissant explosif, était fabriqué pour le gouvernement américain à Holston Ordnance Works, sur les sites de Tennessee Eastman. Au plus fort de la production, vers la fin de la guerre, l’usine de munitions produisait un million et demi de livres d’explosifs par jour. De 1943 à mai 1947, Tennessee Eastman était responsable de la gestion du complexe de sécurité nationale Y-12 à Oak Ridge (Tennessee), qui produisait de l’uranium enrichi pour le projet Manhattan.

The Soviet Union made no announcement after its first atomic bomb test in 1949—but the US did. This is the hitherto untold story of how the secret was extracted from rainwater.

A parachute-retarded LRL device in a MK-36 drop case. This was a test of advanced principles for achieving high-efficiency thermonuclear burn, and successfully confirmed theoretical predictions. It was said to “show the way to a new range of possibilities in high-yield design”. This was the last Christmas Island airdrop, and the third largest test of Operation Dominic. Yield-to-weight ratio was 0.934 kt/kg (but then this was an experiment, not a final weapon configuration).
