I've always been crazy but it's kept me from going insane - WJ.

After Hwasong-15 test, it is almost certain Unha-3 is retired unless they choose to canibalize Hwasong-7's(Rodong's) in case those get replaced by more advanced liquid fuel or solid fuel missile.

Hwasong-15 could possibly without need of 3rd stage put 300kg object into same orbit as Kwangmyongsong 3-2 and 4.

There's a possibility that North Korea might launch a reconnaissance satellite on February 16, the day of the late Kim Jong-il's birth (the official DPRK biography for Kim Jong-il lists his year of birth as 1942, but Soviet records make clear that he was born in 1941).

This is off topic but hopefully not too much of a digression - do you know the reason for the difference?  I would generally assume it’s a propaganda related reason but I can’t imagine what it would be

The launch of Kwangmyongsong-4 was carried out in 2016 ahead of celebrations of the 75th anniversary of Kim Jong-il's birth. It remains to be seen if the DPRK will carry out a space launch to mark Kim Jong-il's birth this month.

Heard this item mentioned on the 9435kHz VOK (Voice of Korea)  shortwave service 28 Feb 2022:

http://www.kcna.kp/en/article/q/a5ed9ba4f90e3e96d0adee0cb2458f43.kcmsf
Cheong Seong-Chang of the Sejong Institute in South Korea speculates that North Korea may launch a spy satellite to mark the 110th anniversary of Kim il-Sung's birth. If the DPRK successfully launches a reconnaissance satellite into orbit this April, it will emulate the USSR in terms of once again mustering the technological capacity to test homegrown military technology despite being hamstrung by the pitfalls of central planning.

Respected Comrade Kim Jong Un Inspects Sohae Satellite Launching Ground

Pyongyang, March 11 (KCNA) -- Kim Jong Un, general secretary of the Workers' Party of Korea and president of the State Affairs of the Democratic People's Republic of Korea, inspected the Sohae Satellite Launching Ground.

Accompanying him were Kim Jong Sik, Jang Chang Ha and other leading officials of the munitions industry and national defence scientific research sectors and officials concerned of the National Aerospace Development Administration.

Going round different parts of the ground, the respected General Secretary set forth a target for modernizing it and the detailed orientation and ways for doing so.

He learned about and evaluated the present state of the ground, and advanced the task to modernize it on an expansion basis so that various rockets could be launched to carry multi-purpose satellites, including a military reconnaissance satellite, in the future. He also set forth the task for building some facilities in the launching ground.

To enable large carrier rockets to be launched there, he assigned the tasks for reconstructing on an expansion basis the launching ground zone and the facilities for the general assembly and trial gearing of rocket and for the trial gearing of satellite, establishing extra facilities for the injection and supply of fuel and modernizing parts of the launch control facility and major technical posts on an expansion basis.

He also gave detailed instructions as regards the matters arising in modernizing the Sohae Satellite Launching Ground on an expansion basis, including the matters of expanding the capacity of the engine ground jet test site, ensuring the convenience of carrier rocket transport, improving the ecological environment around the launching ground and building a grandstand in the safe zone opposite to the launching ground.

He said that the Sohae Satellite Launching Ground is a place associated with the desire of President Kim Il Sung and Chairman Kim Jong Il for a space power and it is a significant place where our state successfully launched artificial satellites twice with its own efforts and technology, true to the lifetime intention of the President and the Chairman. And he stressed that it is the noble duty of our Party and space scientists and technicians in our era to turn the launching ground, associated with our state's great dream and ambition for a space power, into an ultramodern advanced base and a starting line of space conquest for the future suited to the prestige of the DPRK.

Encouraged by his teachings, the officials, scientists and technicians hardened their strong will to turn the Sohae Satellite Launching Ground into the best model suitable for the dignity and prestige of our state by devotedly carrying out the militant tasks set forth by the General Secretary, fully aware of their mission as space pioneers who should surely carry into practice the grand plan of the Party Central Committee for building a space power, true to the behest of the President and the Chairman. -0-

It seems a North Korean ballistic missile test was used to test their photo reconnaisance camera. The last photo shows a ballistic arc at left of screen. The date at the top of the screen is 27 February 2022, which is the date of a recent missile test. Another missile test was conducted on 6 March. Both tests went into the Sea of Japan. The first test had a range of about 300 km and altitude of 600 km. The second test had a range of 270 km and altitude of 560 km.

Respected Comrade Kim Jong Un Inspects National Aerospace Development Administration

Pyongyang, March 10 (KCNA) -- Kim Jong Un, general secretary of the Workers' Party of Korea (WPK) and president of the State Affairs of the Democratic People's Republic of Korea, inspected the National Aerospace Development Administration (NADA).

Accompanying him were Department Director Yu Jin and Vice Department Director Kim Jong Sik of the WPK Central Committee.

The respected General Secretary was greeted on the spot by leading officials of the NADA and the Academy of Defence Science.

Kim Jong Un learned in detail, from leading officials of the NADA, about the process of scientific research and development intended to hit the goals for attainment of space defence science and technology set forth at the 8th WPK Congress and the 4th Plenary Meeting of the 8th WPK Central Committee.

After acquainting himself with the development and preparations of optical photographing equipment, video transmitter and other communication data transceivers and various kinds of sensors and devices for satellite, he heard reports on the results of the major tests recently conducted by the NADA.

He expressed his great satisfaction over the fact that they confirmed the aerospace photographing method, the operating characteristics of high-resolution photographing equipment and the reliability of image transmission system through the recent important tests.

Seeing the vertical and oblique high-resolution images on specific ground regions taken through the major tests, he highly appreciated the successes the NADA has recently made in settling the image composing and processing technology, the ability of processing a large volume of data communication, the accuracy of control command system, the technology of communication encryption, etc., true to the space development policy of the Party.

The development of a reconnaissance satellite takes an important share in attaining the five major goals for developing the defence power set forth at the 8th Party Congress, he said, stressing once again the strategic significance of the reconnaissance satellite in enhancing the war deterrent of the state and the capability of war preparedness.

Saying that the development of reconnaissance satellite is not merely a scientific research work for the development of information-gathering means, but a work for the protection of our sovereignty and national interests, the exercise of the legitimate rights to self-defence and the elevation of national prestige, he stressed that this urgent project for perfecting the country's war preparedness capacity by improving our state's war deterrent is the supreme revolutionary task, a political and military priority task to which our Party and government attach the most importance.

He called on the officials, scientists and technicians in the space and defence science research sectors to successfully accomplish the development of a Korean-style reconnaissance satellite within the period set by the Party Central Committee by getting united and closely cooperating with each other, true to the WPK's policies for aerospace development and national defence development.

The General Secretary also learned about the construction of the Academy of Space Science and a cosmic environment experiment center.

Noting that it is very important to lay a solid material and technical foundation for the field of space science research so as to attain the high sci-tech goal for space conquest set forth by our state, he stressed the need to give more state support to the space science research sector and examine the important measures for its steady development.

He said that it is our Party's important strategic and tactical policy on bolstering the national defence capability to keep a close eye on and distinguish the character of hostile military actions against the DPRK committed by the aggression troops of the U.S. imperialism and its vassal forces in and around the Korean Peninsula and enhance the capability for controlling situation and improve the rapid counteraction capability of the armed forces of the state according to the relevant situations. And he set forth the militant goals related to the development and operation of the reconnaissance satellite in the period of the five-year plan to implement this policy.

He noted that the purpose of developing and operating the military reconnaissance satellite is to provide the armed forces of the DPRK with real-time information on military actions against it by the aggression troops of the U.S. imperialism and its vassal forces in south Korea, Japan and the Pacific. And he said that the Party Central Committee fully supports the decision of the National Aerospace Development Administration on putting a lot of military reconnaissance satellites into diverse sun-synchronous polar orbits in the period of the five-year plan so as to possess the strong capability for gathering intelligence by satellites.

He expressed high expectation and belief that the space and national defence scientific research sectors would demonstrate to the full the heroic mettle of the defence scientific group remaining boundlessly faithful to the Party and revolution by rising up in the scientific and research campaign to thoroughly carry out the strategic plan of the Party Central Committee and making strenuous efforts.

Cherishing in their hearts the militant task set forth by the respected General Secretary, all the officials, scientists and technicians made a pledge of loyalty to defend the great dignity of our state with cutting-edge defence science, greatly encouraged by his deep trust that gives invincible strength. -0-

It's highly likely that NADA conducted in secret tests of a spy camera reportedly intended for the future North Korean spy satellite that Kim Jong-un has mentioned on occasions. It's common for the photographic apparati of spy satellites to be tested in secret.

Launch expected in April 2023...

On December 18, North Korea Space Development Agency (NADA) conducted a test for reconnaissance satellite development at the Seohae Satellite Launching Station.

A spokesperson for the National Space Development Agency said the main purpose was to “evaluate the capabilities of satellite imaging and data transmission systems and ground control systems”.

A satellite payload equipped with 1 color camera with 20m resolution, and a multi-spectral camera, video transmitter, and other supporting equipment  was launched to an altitude of 500 Km.

The National Space Development Agency announced that it would finish preparing the first military reconnaissance satellite by April 2023.

The name "Unha-3" in the thread title was just the codename for the Paektusan-2 the Kwangmyongsong-3 Unit 1 and Kwangmyongsong-3 Unit 2 launches in 2012 (the failed launch of the Kwangmyongsong-2 satellite was called Unha-2) because the name Kwangmyongsong (the official name for North Korea's satellite class) was inscribed on the first stage of the Paektusan-2 rocket used to loft the Kwangmyongsong-4 into orbit. It is possible that the spy satellite mentioned by Kim Jong-un as under development could be an LEO because the DPRK has yet to master the technological knowhow to make a geosynchronous satellite work, and the earliest American and Soviet spy satellites to be launched were low earth orbit spacecraft.

The reason early US and Soviet spy satellites were launched into LEO was NOT because LEO was technologically more accessible than GEO.  It was because LEO is 100 times closer to the ground than GEO and GEO would require optics 100 times larger (and about 10,000 times heavier) than LEO to obtain the same resolution.

High-res optical spy satellites are STILL launched into LEO for the same reason.

I'm willing to bet the North Koreans will use some sort of portable SLV for this launch. Maybe a SLV optimised version of the Hwasong-15 or Hwasong-17 ICBM systems.

From Yonhap News:
Quote
North Korea's development of a high-thrust engine capable of carrying a rocket has provided a "sure guarantee" for the country to launch various satellites into orbit, according to state media Monday.

Pak Kyong-su, vice director of the National Aerospace Development Administration, made the remarks amid speculation the North is likely to put a military spy satellite into orbit by April.

In an interview by the Korean Central News Agency (KCNA) on Sunday on the occasion of the 14th anniversary of the North's accession to the international outer space treaty, Pak said the North has made "steady" progress in the work to develop "multi-functional and high-performance" satellites.

"It succeeded in developing high-thrust engine for carrier rocket and thus provided a sure guarantee for launching various kinds of satellites into relevant orbits," Pak said in an English-language dispatch carried by the KCNA.

This is probably the first instance of a member of North Korea's space agency mentioning the eventual incorporation of the Paektusan rocket engine into a new Unha-type SLV (called Unha-X by Norbert Brugge), because even though the Paektusan engine is used to power North Korea's Hwasong-12 IRBM and the Hwasong-14, Hwasong-15, and Hwasong-17 ICBMs, the Korean Central News Agency until now did not mention any tests of the Paektusan rocket motor for the SLV that reportedly is intended to carry a reconnaissance satellite.
