thermonuclear bomb

One big challenge: Jackson needed to construct physical visualizations of subatomic activity leading up to the world’s first thermonuclear bomb explosion.

The North described its sixth nuclear test, in 2017, as a detonation of a thermonuclear bomb built for ICBMs.

A special congressional investigative committee led by Rep. Christopher Cox, California Republican, concluded in its 1999 final report that Chinese intelligence agents had obtained secrets on seven U.S. thermonuclear bombs, including the W-88.

“It would now be able to do so, while reserving its ICBMs and thermonuclear bombs to deter the United States from retaliatory annihilation of North Korea,” she said.

It would be the North’s seventh since 2006 and the first since September 2017, when it claimed to have detonated a thermonuclear bomb to fit on its intercontinental ballistic missiles.
