The picture suggests the explosion of a cosmic hydrogen bomb.

This powerful bomb became known as the Hydrogen bomb or H-Bomb.

The H-bomb pictured is not a pure hydrogen bomb which is actually very closely related to the already developed ‘neutron bomb’.

The H-bomb pictured is not a pure hydrogen bomb which is actually very closely related to the already developed 'neutron bomb'.

The test has "proved the technological specifications of the newly developed H-bomb were accurate and scientifically verified the power of smaller H-bomb," said the statement.

When that H-bomb exploded in November 1971, it was the last hydrogen bomb the United States ever detonated.
