News reports are saying NK was hoping to have a weapon along the lines of 400kilotons, and has fallen short...How big were the A bombs dropped in 45, and how would compare even 100 kilotons to that?
Fat man(Nagasaki) yielded 21 kilotons. Little Boy(Hiroshima), about 15.
How do they compare to 100 kilotons? Do the math.
The scary thing is that within 10 years of those two bombings, the Superpowers were testing weapons upwards of 1000 times that power, culminating in the 57 megaton behemoth exploded by the soviets in 1961. The original design called for a weapon that would yield an even 100 megatons, but they decided to scale it down by substituting certain radioactive components with lead. I believe the quote from Kruschev was 'we didn't want to end up breaking our own windows when it went off'.
PS: USGS just confirmed a 4.2 magnitude 'seismic event' in North Korea.
