This is a terrible article.<p>> If the bomb was detonated above London’s St Paul’s Cathedral, it would wipe out a huge chunk of the capital and burn people as far away as Vauxhall.<p>First of all, we're not going to use it on London. Second, they're playing fast and loose with the word "test." No detonations have been involved. I couldn't tell from the article, but it seems pretty unlikely that actual warheads had anything at all to do with the reported exercises.
The tests were of a <i>mockup</i> of a bomb... a <i>dummy</i> bomb with <i>no</i> nuclear material at all, testing only the aerodynamics and guidance of the vehicle itself.<p>We don't even do <i>underground</i> testing of nuclear warheads anymore, just <i>simulations</i> using mathematical modeling.<p>The only thing here that's "terrifying" is the "journalism".
This article is poor. A better one (just) is linked below:<p><a href="https://www.military.com/dodbuzz/2018/05/01/air-force-advances-testing-new-nuclear-gravity-bomb-general.html" rel="nofollow">https://www.military.com/dodbuzz/2018/05/01/air-force-advanc...</a>
