One of the lesser bombshells in Bob Woodward’s new book is Trump’s brag that he has a secret new super weapon. I have some ideas about what he’s talking about - with the caveat that Trump often doesn’t know what he’s talking about and often just makes stuff up. 1/
Most likely, he means the “low-yield” warhead the Navy deployed on its strategic subs late last year. It is about a 5-kiloton yield (about 1/3 the size of the Hiroshima bomb and 1/30 to 1/90th the size of the warheads usually on the sub-launched missiles. https://www.theguardian.com/world/2019/jan/28/us-nuclear-weapons-first-low-yield-warheads-roll-off-the-production-line
Trump’s right that no one else has this weapon BECAUSE IT’S A STUPID IDEA. Listen to this @AtTheBrinkPod episode for more on why it’s idiotic to make nuclear weapons more usable, thus making nuclear war more likely. https://atthebrink.org/podcast/modernizing-doomsday-the-true-cost-of-our-nuclear-arsenal/
Trump could also be referring to the still-secret work on hyper velocity missiles (they go many times speed of sound) or even the newish B-21 bomber. But none are super weapons or will change the strategic balance. They are just more tinder for the fire. Nothing to brag about.
