Here's the official KCNA press release. Apogee 4475 km and 950 km range. Launch time was 02:48 29 November. Not sure if that was UTC or local, but if local (+9 UTC) then that is 17:48 UTC 28 November.

"DPRK Gov't Statement on Successful Test-fire of New-Type ICBM

Pyongyang, November 29 (KCNA) -- The government of the Democratic People's Republic of Korea announced the following statement Wednesday over the successful test-fire of new-type ICBM:

The test-fire of intercontinental ballistic rocket Hwasong-15, newly developed under the political resolution and strategic decision of the Workers' Party of Korea, was successfully carried out.

The ICBM Hwasong-15 type weaponry system is an intercontinental ballistic rocket tipped with super-large heavy warhead which is capable of striking the whole mainland of the U.S. This system has much greater advantages in its tactical and technological specifications and technical characteristics than Hwasong-14 whose test-fire was conducted in July last, and it is the most powerful ICBM which meets the goal of the completion of the rocket weaponry system development set by the DPRK.

Upon authorization of the WPK and the government of the DPRK, ICBM Hwasong-15 was launched at 02:48 on Nov. 29, Juche 106 (2017) in the suburbs of Pyongyang under the guidance of Comrade Kim Jong Un.

After making a 53-minute flight along its preset orbit, the rocket accurately landed in the target waters set in the open sea in the East Sea of Korea.

The test-fire was conducted in the highest angle launch system and it had no adverse effect on the security of neighboring countries.

The rocket soared to the highest altitude of 4 475 km and then flew the distance of 950 km.

After watching the successful launch of the new type ICBM Hwasong-15, Kim Jong Un declared with pride that now we have finally realized the great historic cause of completing the state nuclear force, the cause of building a rocket power.

The great success in the test-fire of ICBM Hwasong-15 is a priceless victory won by the great and heroic people of the DPRK who have upheld the WPK's line on the simultaneous development of the two fronts with loyalty without the slightest vacillation despite the vicious challenges by the U.S. imperialists and their followers and manifold difficulties.

The development and advancement of the strategic weapon of the DPRK are to defend the sovereignty and territorial integrity of the country from the U.S. imperialists' nuclear blackmail policy and nuclear threat, and to ensure the peaceful life of the people, and therefore, they would not pose any threat to any country and region as long as the interests of the DPRK are not infringed upon. This is our solemn declaration.

As a responsible nuclear power and a peace-loving state, the DPRK will make every possible effort to serve the noble purpose of defending peace and stability of the world."

The Pentagon announcement quoted above gives the launch site as being "Sain Ni".   Is this a new launch site or is it one which we know under a different name?
They are mobile and being launched from multiple sites.
This message reflects my personal opinion based on open sources of information.

Maybe the Hwasong-15 is a Hwasong-14 with a larger second stage considering the duration of the burn.

The logical next step would be use of a second stage with 4, rather than 2, engines. That configuration has already flown in Iran.

How much commonality is there believed to be between the two?

Here’s some analysis of this latest launch.

This is always a good point to keep in mind.

Quote
We do not know how heavy a payload this missile carried, but given the increase in range it seems likely that it carried a very light mock warhead. If true, that means it would be incapable of carrying a nuclear warhead to this long distance, since such a warhead would be much heavier.

This article has even more analysis. Interesting point about it being a nighttime launch.

Is the range assessment of 13,000 km accurate?

Aren't major European capitals now also within North Korean Missile range, and not just American ones? I'm assuming their quickest route to hit Europe would be launching over the polar region.

Well the UK is certainly in range.

What's uncertain is whether or not a live warhead can be attached to these missiles, whether it could be successfully deployed, and whether it could survive re-entry. Without that, which will never be tested, this could still all be a grand poker bluff by NK at this point in time.

The upcoming Minuteman launch from VB won't be.

Yes, we can't know if range and/or capability are for real until they fire a warhead and detonate it.
Which is why "stop daring them to do it!" has become part of the arms control experts message to politicians.

(As discussed earlier America, China and Russia did it. China fired and detonated a nuke over their own nation as 4th test after US politics said they could not.)


Pictures are out. And no, not just 2 more vernier engines.
This time a 9 axle TEL, larger in diameter and length, blunt tip. 2 1st stage engines, no more 1st stage verniers..
My first impression is that it looks a bit like a new take on the HS-13 (2nd version).

Here is a large set of picture.

Here's the KCNA release. Says the nine axle T/E is 100% North Korean. Photo clearly showing the two engines of the first stage. Looks like a Titan II class missile. Attached is a zip file of all the photos.

"Kim Jong Un Guides Test-fire of ICBM Hwasong-15

Pyongyang, November 29 (KCNA) -- A test-fire of the inter-continental ballistic rocket Hwasong-15 was successfully conducted on November 29 under the guidance of Kim Jong Un, chairman of the Workers' Party of Korea, chairman of the State Affairs Commission of the DPRK and supreme commander of the Korean People's Army.

Kim Jong Un personally supervised the whole course of the test-fire.

He indicated the orientation of developing a new type rocket that can make the final victory of the country in the showdown with the U.S. imperialists and gave detailed instructions every day to the Academy of Defence Science for doing so and thus made sure that the Hwasong-15 weapon system was successfully completed.

Upon receiving the report that it is ready to test-fire the new type ICBM on Nov. 28, he came out to the place where technical preparations for the rocket was under way late at night to see the 9-axis self-propelled launching vehicle manufactured by workers of the munitions industry.

He praised them for having successfully made the vehicle to be impeccable.

He expressed great satisfaction over the fact that such vehicles can be manufactured as many as the country wants now that the munitions industry has made a breakthrough in putting the production of all parts of the vehicle on a domestic and Juche basis 100 percent.

He went to the launching ground and meticulously guided the pre-launch processes one by one including the one for vertically standing the rocket.

At an observation post for command he learned in detail about the launching plan and issued an order to launch the rocket.

The rocket successfully blasted off and soared into the sky.

The ICBM Hwasong-15 soared to the highest altitude of 4 475 km and made a flight over the distance of 950 km for 53 minutes before making an accurate landing in the preset waters in the open sea in the East Sea of Korea.

The test-fire confirmed that all the integers of the weapon system have satisfactorily complied with the requirements of design and that it is capable of fully ensuring reliability in combat situation to serve its mission as strategic weaponry system.

Particularly, the accuracy of hitting targets by posture control and speed correction in the mid-flight section, accuracy in operation of high-thrust engine to which propulsion vector control is applied and the engine of high specific thrust was confirmed, and the accuracy of design integers of subsequent guided and stabilization systems was verified.

Also confirmed were mobile and hoisting capabilities and operational reliability of launching system of the nine-axis self-propelled launching vehicle newly developed and completed.

The test-fire also re-confirmed the control and stabilization technology, phase-separation and start-up technology and the safety of warhead in the atmospheric reentry environment that had already been confirmed.

The ICBM Hwasong-15 weapon system represents the weapon system peculiar to the Workers' Party of Korea, which was developed with domestic efforts and technology 100 percent to suit the specific conditions of the country. With this system, the DPRK has become possessed of another new-type inter-continental ballistic rocket weaponry system capable of carrying super-heavy nuclear warhead and attacking the whole mainland of the U.S.

Greatly satisfied with the at-a-go success in the test-fire of the newly developed ICBM Hwasong-15, respected Supreme Leader Kim Jong Un was so excited to express his great satisfaction and extend his heartfelt gratitude to all those who took part in the development of the new type rocket weapon system.

He said that the day was a significant day when the historic cause of completing the state nuclear force, the cause of building a rocket power was realized, adding that the day, on which the great might of putting the strategic position of the DPRK on a higher stage was given birth, should be specially recorded in the history of the country.

The dazzling achievements made in all fields of the country recently including the field of national defence science are a great victory which can be won only by the heroic people of the DPRK who remain true to the cause of our Party without vacillation, weathering all tempests of history.

He warmly congratulated scientists, technicians, workers and officials in the field of the defence science who demonstrated once again the dignity and might of Juche Korea by succeeding in the test-fire of the newly-developed ICBM Hwasong-15, and had a photo taken with them.

He was accompanied by Jang Chang Ha, Jon Il Ho, Jo Yong Won and Yu Jin. -0-"

To use very round numbers comparing against Titan II the HS-15 has 2/3 the length and diameter, 1/3 the volume.

It is however more or less UR-100 sized, similar diameter with HS-15 slightly longer overall.

It looks to be the 2 nozzle 80 ton thrust engine, with the 4 engine upper stage. So, yeah, now they have either a small ICBM or a decent IRBM, based on the payload mass.

Depends on how closely they captured the RD-250's performance with this seemingly derivative engine, I guess.

Is it case of clustering more of the same engine rather than using an improved version or a different model entirely?
