The Last Word On EMP

There is a small industry around a bizarre idea. Nuclear weapons are known to emit a powerful electromagnetic pulse when they explode. So grifters, cheap novel-writers, and proponents of moar defense spending push the idea that a random bad actor would detonate a nuclear weapon at high altitude over the United States and WIPE OUT ALL OUR ELECTRONICS!

This is a dumb idea, for many reasons. I have debunked it many times. The group referred to as “Nuclear Twitter” regularly mocks it.

Kelsey Atherton, a New Mexico friend, has written what should be the last word on EMP. The title says it all:

Electromagnetic Pulses Are the Last Thing You Need to Worry About in a Nuclear Explosion

But if you’d like more detail, Kelsey has it for you.

Iran Is Far From A Nuclear Weapon

I’ve been writing this now since 2012 or earlier, but reporters and editors don’t care to learn about the uranium supply line and the processes that form it into a nuclear weapon. Or they like sensationalized clicks better. So here it is again.

The IAEA defines what it calls a “significant quantity” of enriched uranium as 25 kg of U-235 in enriched uranium. That’s approximately enough for a nuclear weapon, although it varies with the weapon design. The IAEA needs an arbitrary number like that for reporting on its inspections. It’s a quick rule of thumb. (If you click that link, you’ll see others writing about it in 2012.) Read More

What Would It Take For Turkey To Build A Nuclear Bomb?

That was how David Sanger teased his and William Broad’s article on Twitter.

Unfortunately that is not how the article is written. If you want to read it, write it, they say, so here goes.

In September, Turkey’s President Recep Tayyip Erdogan said “Some countries have missiles with nuclear warheads,” but the West insists “we can’t have them. This, I cannot accept.” Read More

Those New Russian Weapons

Vladimir Putin has claimed that Russia is building a suite of advanced nuclear weapon delivery vehicles – Hypersonic missiles, an underwater drone, a nuclear-powered cruise missile. The American Missile Defense Review is, in part, a response to that.

The new Russian weapons sound amazing! The underwater drone, Putin would have us believe, could sneak up on the east coast of the United States and cause a radioactive tsunami! The nuclear-powered cruise missile could cruise around the globe twice and then nuke Florida!

Putin has shown all that on animated videos. A few frames appear to be actual photos, but the videos are mostly animation. Read More

A Russian Nuclear Cruise Missile?

Back in March, Vladimir Putin unveiled a number of new nuclear weapons. But they’re not operational, and, in my opinion, are unlikely ever to be.

One was the Poiseidon (Status-6) underwater drone, supposedly designed to hit the east coast of the United States with a radioactive tsunami. Oh, and did I say that it’s undetectable? Read More

A Dozen Facts Donald Trump and Mike Pompeo Need To Know To Negotiate With North Korea

The primary issue that is being negotiated with North Korea is its nuclear weapons and the missiles they might be mounted on for attacks on the United States and its allies, South Korea and Japan. A meaningful agreement will have to include many technical issues.

Donald Trump and Mike Pompeo are not nuclear or rocket scientists, nor can we expect most politicians to be. But the technical facts are no less difficult to learn than the economics. (Oops! They get that wrong, too. I will push forward anyway.) Pundits commenting on the negotiations and people who simply want to understand may find this list useful. Read More
