We can see that the Hwasong-12 after lift-off reveals one main engine and four auxiliary engines.
Previous informations about a 80 to 100 tons-force liquid propellant engine are now confirmed by this image.
The central main engine is in the 80-100-tf range.

Comparison with the previous September 13, 2017 video confirmes the payload fairing nosecone's hemispherical shape, red color and relative diameter.
This time the second stage diameter seems smaller (~estimated 2 to 2.4 meters ?) than the first stage (~possibly 3 to 3.3 meters ?), and no longer of the same diameter (as the Unha-9B).
Probably an earlier version of the Unha-9 (I choose to call the Unha-9A).
However, the Diameter to Length ratio does not change.
A national exhibition of experimental apparatus and teaching aids and an educational books exhibition took place at the Sci-Tech Complex in Pyongyang, some days ago. The DPRK has set this year as a year of science and education.
On display at the exhibitions were many experimental apparatuses, educational aids, multimedia programs, simulation experiment and practice programs and educational books presented by education institutions and education publishing houses.
The exhibitions served as good occasions conducive to putting education on an IT and modern basis and bringing up the rising generation to be reliable masters of a talent power.

A first launch for the new Unha-9 seems imminent, as South Korea's KARI also just announced the first test launch of its pilot launcher, south Korean equivalent of the Hwasong-12/14, the two stages KSLV-2 II with a diameter of 2.6 meters and total length of 26 meters, and powered by a single-chamber 75 ton-force engine for October 2018.
The next south Korean launcher, the KSLV-2-III to be launched by December 2019 will be powered by four 75 ton-force engines, developping a liftoff thrust of 300 ton-force similar to the Unha-9, powered by four 80 ton-force Paektusan engines.
The first test launch of the Korean launch vehicle, which was originally developed after the launch of the Naro LV, is scheduled for October this year.
The lower part of the rocket with the moving gimballed engine was assembled with the first stage.
Inside the rocket, every electronic equipments have also been connected.
The rocket is 2.6 meters in diameter and 26 meters in length.
This completes the assembly of the first test LV with the 75-ton thrust engine.
The rocket, which has been assembled, is standing up for the ground static test, and it will be the first test launched in October.
We are developing the next South Korean launch vehicle, with a first stage thrust of 300 tons.

The next step is Sepehr and Sarir that can put 1,000 kg satellites into 1,000km altitude orbits. By adding micro thrusters and several side boosters, the Sarir heavy launcher can put payloads into 36,000 km altitude orbits. It is expected to be build during the fifth development program of the country (2010-2015).

You are not ignoring that there are guidances provided to teachers in North Korea about how to draw rockets, so the clues are always timely leaked, as the maidden launch is expected for October of this year.
This kind of paper kites are either build by children for themselves or sold in public places in most cities of China and North Korea.

Iran's Shiva Khademi was one of the winners of The 2018 Stenin Press Photo Contest. The photo contest was first organized in December 2014 in memory of Russian photojournalist Andrei Stenin. He was killed while on assignment in the Donetsk region of Eastern Ukraine on August 6, 2014 after his car was shot at and burned on a highway. The photo contest aims to promote young photographers and attract public attention to photojournalism.
According to global statistics, one percent of the world’s population consists of twins and multiples. Based on the statistics from Iran National Organization for Civil Registration, the multiple births in Iran have been up to three percent of births since 2011. In spite of their low percentage, multiples have had a profound impact throughout history. Sometimes they have been worshiped as gods, sometimes as charmers. Twins have marked their footsteps in myths, and accordingly, there are a lot of resemblances in various cultures; such as Castor and Pollux who were known as “the heavenly twins” and are often associated with Gemini; Romulus and Remus, Jacob and Esau, Horus and Seth, etc.
When I faced identical twins, I was mesmerized by their matching outfits, similar make-up and hairstyles and body language; I was astonished by the fact that they finished each other’s sentences or uttered words with the same tone together; they even smiled or had a think at the same time, sometimes had similar dreams, similar exam results, and they had identical tastes… and these similar behaviors were strange and astounding, yet so ordinary and innate according to themselves.
The question that led to the idea of this photo collection in my mind was that, is their identity “one” that has been repeated twice, or do they have their own independent existence, despite being double? Are they a manifestation of beauty which has been duplicated? Is their nature a line between reality and fantasy? It’s all as if they touch the flowing forgotten feelings and waken something deep within us, which originates in the depth of obscure ancient rituals and cultures.
▲2. Launchpad seemingly destroyed by floods on 29 March 2019 satellite imagery of IKSLC.
No more Safir-2 and Safir-1 SLV launches for this year.
▲3. The only available launch pad, as of April 2019: Sohae.
Off topic: @SOHEIL, recently, in a relevant thread I have exposed your criminal activities. Now in another one, I will demonstrate that you also intentionally lied to the readers.
Images taken from military.ir, the Farsi language forum explicitly presented Qaem SLV as a solid propellant one.
While Safir is the generic name for a family of liquid propellant space launchers.
▲1. The Qaem solid propellant SLV as presented in military.ir forum
▲2. The Qaem solid propellant SLV with strap-on boosters as presented in military.ir forum
▲3. The Qaem solid propellant SLV CGI as presented in military.ir forum
▲4. Screen capture of the said forum when accessed (19 FEB 2019).
Conclusion
Therefore @SOHEIL is not only a very rude, terrible person, @SOHEIL has also intentionally mislead the readers with a fabricated FAKENEWS cooked up by himself, enough to warrant a ban.

So is first stage of new unha rocket 3 RD-250 engines as speculated? When is targeted launch date? KJU seems to have forgotten his country has a space program. No SLV launch since February 2016!

From official North Korean sources, back in 2012, it was disclosed that the manned Unha-X launcher would have a mass of 400 tonnes.
Kwangmyongsong SLV (the 2016 Unha-4) can send a 1'000 kg payload to a 500 km LEO. The three stages Unha-9 SLV can send a 2 tonnes payload to a 500 km LEO.
With only 4 sets of 80 tonnes force Paektusan-1 engines, totalling a liftoff thrust of 320 tf, the two stages Unha-IX-E2 with a mass of 200 tonnes could only send a single seater E2 (Mallima-1B in Korean) manned capsule with a mass under two tonnes (~1'800kg) at some 250 km LEO altitude.
Note: E1 is the only known Persian designation for the suborbital one seater manned capsule. I called it Mallima-1A for more clarity. While the orbital version is called by Me "E2" or Mallima-1B, by analogy with the U.S.' Mercury-Redstone and Mercury-Atlas concept. Also following this logic, the Redstone would be replaced with a Safir-1D SLV in Iran and a Hwasong-15 SLV in North Korea for the suborbital mission.
With 4 additional strap-on boosters, increasing the liftoff thrust to 8x 80 tonnes force or 640 tonnes force, the 400 tonnes manned Unha-X-F1 can place a dual/three seaters F1 (Mallima-2 in Korean) spacecraft at some 350 km LEO.
Therefore the very ambitious North Korean space conquest plan started in 2017, to perform a spacewalk by 2022 will need at least 6 launches to ensure the reliability of the Unha-9 as a man-rated SLV.
Two Observation satellites
Two Communications satellites
One Lunar orbiter
One GEO satellite
Notice the lunar orbiter will precede the GEO satellite as explained below:
▲1. Lunar gravity assist used to place North Korea's satellite into the GEO belt.
The suborbital part is only a speculation based on the Iranian plan. If it exist, then it should be conducted in parallel, as the launcher is not the Unha, sharing in common only the spacecapsule and the 10 astronauts selection.
India can never catch up with North Korea's 2022 spacewalk, as ISRO has not even considered this possibility, and time is running out.
As a last resort, only Modi Ji performing his famous Yogic Earth Rotation could snatch the 4th space superpower place from North Korea!
The fact that his remarks on the launch of manned spacewalk is not an exaggeration and can be seen from the scale of the facilities of the West Sea [Sohae] Satellites Launch Center. According to this reporter, the launch pad of the West Sea [Sohae] Satellites LC was designed to launch a 400 - ton ultra - large carrier rocket. In fact, the height of the launcher is more than 50m. He described it as a super large carrier rocket, but if it is a 400 ton class rocket, it is not a carrier rocket that carries satellites, but a carrier rocket that carries a manned spacecraft.
On April 12, 1961, the mass of the Soviet manned spacecraft Vostok 1, which flew to space with the first human Yuri Gagarin (1934-1968), was 5.9 t. And the two-stage carrier rocket of the Voskhod spacecraft that performed the first manned spacewalk was 30.84 meters long, the first stage diameter was 2.99 meters, and the mass 298.4 tons. This means that the Soviet Union developed a powerful rocket with a total mass of 304.3 tons, that could launched a manned spacecraft.
Kim Jong Un seems to include a plan to launch a manned spacewalk as well as a lunar exploration satellite in the chairman's first plan for space conquest. The model of the Unha-9 built next to the stage of the 2012.12.21 ballroom is not rocket model for manned space flight. Chairman Kim Jong Un will carry out a step-by-step implementation of the space conquest plan to launch a manned spacewalk on the new type of carrier rocket Unha-10, which is totally different from the Unha-9 model. It is to be realized in the future. In the 10 years period from 2012 to 2022.
Images of the Hwasong-15 test launch of 29 November 2017, shows that the two Paektusan-1C engines of the first stage differ from the 80-tf Paektusan-1A (tested on March 18, 2017 as a static ground test) and the 100-tf Paektusan-1B (powering the Hwasong-12 and Hwasong-14).
Indeed, the two Paektusan-1C engines of the Hwasong-15 are fully gimballed on two axis, to conduct the Roll and Attitude Control (RAC), as no verniers can be seen.
The Paektusan-1A engines has a single-turbopump and a single-combustor. It is static.
The Paektusan-1B engines has a single-turbopump and a single static combustor plus 4 swivelling verniers.
How can we tell whether the Hwasong-15 is made of two fully gimballed Paektusan-1D engines or not of a single Paektusan-1C engine with two gimballed nozzles as incorrectly assumed by SOHEIL?
Firstly, by looking at the turbopump cover (the orange color box), the length suggests it might have enough room to house two turbopumps and not only one.
Secondly, as illustrated by some internet photogrammetric analysis, the Hwasong-15 is shown with two turbopump's exhausts, meaning two separate set of Paektusan-1D engines.
While plume analysis indicates that during the maiden test flight of the Hwasong-15 of 29 November 2017, the first stage had only one turbopump exhaust (corresponding to a Paektusan-1C), in future version, it might be increased to two (Paektusan-1D).
The first known commercial resin Hwasong-15 ICBM 1/144 scale model confirmes the previous assessment.
Again, the Hwasong-15 ICBM is presented being powered by two independent fully gimballed Paektusan-1D engines, each with a separated turbopump and exhaust pipe!
Implying a thrust at liftoff of 2x 80tf!
