Where did the US test the first hydrogen bomb?

The United States conducts the first airborne test of an improved hydrogen bomb, dropping it from a plane over the tiny island of Namu in the Bikini Atoll in the Pacific Ocean. The successful test indicated that hydrogen bombs were viable airborne weapons and that the arms race had taken another giant leap forward.

How big was the explosion of the hydrogen bomb?

Observers said that the fireball caused by the explosion measured at least four miles in diameter and was brighter than the light from 500 suns. The successful U.S. test meant that the ante in the nuclear arms race had been dramatically upped. The Soviets had tested their own hydrogen bomb in 1953, shortly after the first U.S. test in 1952.

When did the US drop the first H bomb?

The first successful American test was conducted in the Pacific in 1952, the first Soviet test in the following year. An American crash programme under Teller was ready to drop the first H-bomb ever launched from an aircraft in May 1956.

Where was the hydrogen bomb dropped in 1956?

The practical application of dropping the weapon over an enemy had been a mere theoretical possibility until a successful test in May 1956. The hydrogen bomb dropped over Bikini Atoll was carried by a B-52 bomber and released at an altitude of more than 50,000 feet. The device exploded at about 15,000 feet.
