Ton, kiloton... whatever. /s
Look at that graphic. A MOAB is three times bigger than the Hiroshima atomic bomb.
My father was a member of Task Force 132.4 at Eniwetok Atoll, Operation Ivy. He witnessed the detonation of Ivy Mike and Ivy King. Ivy King was the largest yield to date fission bomb. Ivy Mike was the very first fussion device measured in megatons, not kilotons. I say device because it was not a deliverable ordinance. It was a “wet” device using liquid hydrogen housed in a huge building on one of the islands of the atoll. The firing mechanism spanned 2 islands. I have most of his documentation from that time. Even a leather patch that a militaria dealer was stumped with. He’d never seen anything like it.
