An interesting little story, though this website isn’t always the most accurate.

The new Ford class aircraft carrier has been designed with extra electrical capacity for laser weapons.

In addition the USN SSBNs are now fielding small yield nukes on some of their missiles.

Go Navy

OK, it isn’t likely, but it is an interesting article.

On this day…

on October 30th, 1965, the largest man-made explosion in history occurred when the Soviet Union detonated the Tsar Bomba, a Hydrogen bomb that yielded between 50 and 58 megatons. (sources differ)  The explosion was so powerful, the shockwave travelled through the earth and bounced back twice.

Even though it was an air burst, it left a huge crater.

For comparison, the largest US nuclear test explosion was the Ivy Mike test, which yielded 10.4 megatons. (that explosion was over twice as large as it was meant to be, due to a miscalculation by the scientists involved, and if the words miscalculation and nuclear together don’t scare you, you haven’t been paying attention.)

If you want to compare how big the Tsar Bomba explosion was compared to Fat Man and Little Boy, you can nuke any place on Earth (virtually, of course) using the website Nukemap.  They have the Tsar Bomba as a pre-programed choice.

Actually, there is a kit of the Tsar Bomba.  I am in the process of adding it to my nuke collection.
















Amodel Tsar Bomba with a Brengun MXY-7 Ohka for scale.  Clearly the Russians weren’t worried about making it compact.









A USAF RC-135 nuke sniffer was flying off the coast when the Tsar Bomba was dropped.  This is a photo they took of the mushroom cloud.

Pigs, it turns out, could lead to the denuclearization of North Korea.  The present US administration has made a resolution of the North Korea problem one of its top priorities.  North Korea teeters on the edge of starvation, at least for the vast majority of its population.  Now, North Korea has apparently been hit with “pig ebola” that has already struck neighboring China.  North Korea gets 80% of its protein from pork.  If this hits North Korea as hard as it has hit China, then it may provide an opening for the US to trade pigs for denuclearization.  Time will tell.

Still playing with nukes

The USAF is still testing an developing aircraft dropped nuclear weapons.  Story here.  While an air dropped nuke may seem anachronistic in this day and age, it is worth keeping more options available.  The more options we have, the less chance we end up having to use one of them.

More on that Russian nuclear accident

More of the story here.  I suspect that we may not know the full story of what happened here for 20 or 30 years, if ever.  However, I think this is a much more important story than we’ve been led to believe and I hope reporters keep digging.

Earth’s inner core

Interesting article on study of the Earth’s core using data generated from old Soviet nuke tests.  What they don’t tell you in the article is one of the nuke tests was the Tsar Bomba, the most powerful man-made explosion ever.  There is a kit of the Tsar Bomba and I want it.

BTW, this is what the effects of the Tsar Bomba would look like if an air burst detonation occurred over Louisville, KY

or should the fact there was a small explosion in Russia involving a release of radiation be a bigger deal? WTF?


UPDATE:  Here is a much more detailed analysis of what we know or think we know.
