North Korea’s Sixth Nuclear Test: A First LookCommercial satellite imagery from Planet, obtained the day after North Korea conducted its largest test to date (currently estimated in the 100+ kiloton range), appears to show numerous landslides throughout the Punggye-ri Nuclear Test Site and beyond. The area of these surface disturbances, which include numerous areas of pre-existing gravel and scree fields that have apparently been lofted in place from the tremors,[1] is centered about Mt. Mantap (elevation. 2205 meters). These disturbances are more numerous and widespread than what we have seen from any of the five tests North Korea previously conducted. There does not appear to be any evidence of a collapse crater, as might have been suggested from the post-test tremor. The resolution of this imagery is presently insufficient to show any other damage, (e.g. to buildings at the base of the mountain in the support areas). However, once higher resolution imagery becomes available, additional details will become known and we will report on them at that time.

Should the nuclear/thermonuclear weapon discussion be separated from the missile thread?

Isn't it better to contain it all in one thread, to stop thread creep?

Maybe it's just me but I thought that the design of bombs had already caused the thread about *missiles* to creep rather a long way. Still, no problem.

NORSAR has revised their assessment of the 6th nuclear test, now 200-300kt.

In rocket news the 3 rockets fired on August 26th were identified as KN21 aka Scud-B MaRV. This modification was first seen on this years parade.

Probably a max range test with a minimum payload. R-27 could do that carrying 650 kg of payload, as a reference.

With distance of 3700 km and height of 770 km, initial velocity is approximately 6100 m/s.
It is still within the known capacity of HS-12 IRBM.
We'll see if KCNA reports the launch and in which terms.

If there is any way to calculate the final velocity of the HS-14 first stage, that might give us some insight into the mass proporties of the second stage, based on the above numbers.

For those who collect serial numbers. This one was launched directly from the TEL, unlike the previous launch. The TEL got scorched quite a bit, but this allows a more rapid response.

I'm curious why a direct tweet link from the US president calling out Kim and his missile launches would get deleted? All the news media covered it and everything the president communicates will be archived in the Library of Congress for posterity...

This thread needs more posts about North Korea missile tech, and less about the political stuff.
In particular, compare and contrast Hwasong 12 vs Hwasong 14.

That will come in handy when one lands on you and without the politics the missiles would not exist...

The news today is about North Korea's plan to test a "hydrogen bomb over the Pacific Ocean". Any thoughts on how that might be carried out? Is North Korea planning to launch a live warhead on a missile that likely has to fly over Japan? The U.S. and Soviet Union carried out such tests before the test ban treaty, but those were on controlled test ranges.

I heard possibly using a ship, unconfirmed...

China actually did the same thing, after US president said that China doesnt have a viable delivery platform for its nukes, so they are not worried about it (which sound very similar to what many are saying now).
