US to build new nuclear gravity bomb
(www.defensenews.com)
This is a most excellent place for technology news and articles.
You might also find my UAP write-up interesting. Particularly, the section on USAF Project 1794. (Scroll to the images of the actual report.)
My article is very long, but it's comprehensive and thoroughly cited with valid sources.
Thank you, I've saved that for a quiet moment.
