Speculation ON

Given that China's new line of launchers is based on the RD-120 engine, and it is not clear how China got the design, is it possible that the same source provided the design to NK, which then converted the engine to storable fuels?

Speculation OFF
China's are from Ukraine. They are almost identical and their are threads on this. As for North Korea there is not any strong evidence to support this theory and the UN has yet to issue its findings from its recently conducted review. All I can say is wait for a bit.

The fact that China's RD-120 derivatives originated from a Ukrainian source somehow means that NK could not purchase from the same source?

Converting the engine to storable fuels? This is not easy. For NK, apparently there are some better choices

No, it’s more that the photos and videos Yankton NKs engines show them to be very, very different from RD-120

North Korea preparing long-range missile test: RIA cites Russian lawmaker

Quote
MOSCOW (Reuters) - North Korea is preparing to test a long-range missile which it believes can reach the west coast of the United States, a Russian lawmaker just returned from a visit to Pyongyang was quoted as saying on Friday.

Anton Morozov, a member of the Russian lower house of parliament’s international affairs committee, and two other Russian lawmakers visited Pyongyang on Oct. 2-6, Russia’s RIA news agency reported.

“They are preparing for new tests of a long-range missile. They even gave us mathematical calculations that they believe prove that their missile can hit the west coast of the United States,” RIA quoted Morozov as saying.

“As far as we understand, they intend to launch one more long-range missile in the near future. And in general, their mood is rather belligerent.”

Relevant to this thread.

Doubts Growing US Will Always Defend Asian Allies

Quote
SEOUL --- In South Korea and Japan there is increasing support for the deployment of nuclear weapons to defend against the growing North Korean threat, and due to public concern that the U.S. may no longer be counted on to aid allies with extended nuclear deterrence.

The U.S. Defense Intelligence Agency estimates North Korea may have as many as 60 nuclear weapons, and that it might have successfully miniaturized nuclear warheads to fit on its arsenal of 1,000 missiles.

N. Korea seems to have a problem with re-entry capability on its ICBMs.

I am surprised that this has not been discussed earlier.

It has been widely discussed at the time of the launches.

The evidence that the reentry vehicles failed was not that great.
It still looked like the NK reentry vehicle survived long enough for an air burst, using yield from the last test. *
The armscontrolwonks once more dug up a declassified study about early US reentry testing. Most of the failed test did not break up but veered off course, hitting outside the systems CEP. (Consistent ablation rates seem to be hard.)

The articles are not that rosy if you say no ground burst for NK and likely just hitting a different part of a city target.  :(


*: Some articles said it broke up at 1 mile height. Which happens to be the default air burst height for 150kt on nukemap...
What I would like to know is how would it look if they stuffed their gadget with conventional explosives and set it for airburst. We know that they rigged some rocket stages with self destuction charges to prevent recovery or at least make it harder.

BBC reporting that North Korea has fired a ballistic missile. They are quoting South Korean reports.

In that article it’s described as a new ballistic missile.

According to CNN it is still in the air  ATM possibly a high altitude flight to test the RV...

NK missile impacted Sea of Japan, so no Japan overflight this time.
Could still be one of the high apogee tests, or just a smaller missile.

And now Yonhap matches my guess quite accurately. (My guessed TLE gives 4420 km apo, 920 km range)

By the altitude achieved it could be a Hwasong-14.

Possibly testing the re-entry vehicle again after reports of prior failures on past launches.

IMMEDIATE RELEASE    No. NR-401-17
Nov. 28, 2017
Statement by Pentagon Spokesman Col. Robert Manning on North Korea ICBM Launch

The U.S. Department of Defense detected and tracked a single North Korea missile launch today at about 1:17 p.m. EST. Initial assessment indicates that this missile was an intercontinental ballistic missile (ICBM).

The missile was launched from Sain Ni, North Korea, and traveled about 1000 km before splashing down in the Sea of Japan, within Japan's Exclusive Economic Zone (EEZ). We are working with our interagency partners on a more detailed assessment of the launch.

The North American Aerospace Defense Command (NORAD) determined the missile launch from North Korea did not pose a threat to North America, our territories or our allies.

Our commitment to the defense of our allies, including the Republic of Korea and Japan, in the face of these threats, remains ironclad. We remain prepared to defend ourselves and our allies from any attack or provocation.
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."
