Today we visited the Atomic Test Museum with my mother.  It was a great museum:

This 2 foot tall warhead has a 15KT yield, roughly comparable to the bomb dropped on Hiroshima:

The museum focused on testing, with an extensive section about the US underground test program here in Nevada:

They had the shell of a B53 bomb on display.  With a 9MT yield, it would flatten all buildings within 10 miles of the drop point:

Here’s a scale model showing the bomb to size under the deploying bomber:

We had lunch at a restaurant nearby.  Another great day in Las Vegas!
