Probable Ballistic Missile Training Facility Located

AccessDPRK has located, with moderate probability, a ballistic missile training facility for North Korea’s Strategic Rocket Forces.

Located near the city of Jangjin at 40.328529° 127.228468°, Landsat imagery shows that the facility was established ca. 1994 and high-resolution images are available from Google Earth starting in 2009. 

North Korea has an estimated twenty operating ballistic missile bases, and most have gone undescribed in public sources except for brief mentions of the existence of “Base A” or “Base B”. Many of these bases have their establishments in the 1980s and 1990s, coinciding with an important period of missile development in North Korea as the country moved away from simply reverse engineering Egyptian-sourced SCUDS and began to develop their own indigenous weapons.

North Korea also has a number of areas used for testing rocket engines and the missiles themselves; areas such as the Hodo Peninsula Testing Facility, the Sinpo Shipyard, and many more. Getting even less public mention are the numerous smaller parts of the country’s missile infrastructure.

There’s more to developing a credible ballistic missile force than just having the ability to launch them. Having locations to do everything from research and development to training your nascent missile force personnel in handling, moving, mating, fueling, raising, and arming the missiles is necessary.

If no one can drive the large vehicles needed to move the weapons from one place to another, you’re left with sitting targets.

The Jangjin complex is one of the smaller ballistic missile-related facilities in the country. From its headquarters to the rear of the base is only about 1 km, while some operating missile bases cover dozens of square kilometers. 

The base is situated in a forested part of Jangjin County and is arranged along a single dirt road. Moving south from the headquarters are four transporter-erector launchers (TELs), each with their own bunkers for protection.

There are also smaller objects and excavated emplacements throughout the complex, but they are too nondescript for me to identify. 

The TELs are approximately 17 m long and 3 m wide, while the bunker structures are 18-19 meters long and 5 meters wide. Each one is also protected by an earthen berm positioned roughly 28 meters away from the bunker entrances. 

A question exists whether or not the base is currently active. A review of Google Earth imagery shows that the TELs barely move, if at all, over a sequence of seven available images from 2009 to 2018. The TELs are not seen fully housed inside the bunkers nor are they seen moving around other parts of the base. 

The headquarters and road are maintained, suggesting the site hasn’t simply been abandoned, but what its current status is isn’t known, as North Korea’s modern intercontinental missiles are too large to fit the TELs at Jangjin. However, that may help give us an answer.

Jangjin may have been one of the first dedicated ballistic missile/TEL training bases constructed. At the time, the country only possessed short- and medium-range ballistic missiles (which fits the size of the visible TELs). Training for these missiles and equipment is still needed, but the country’s focus has since been on developing and deploying larger and larger missiles leading to the need for the enormous 11-axle TEL seen in 2020. Jangjin may simply no longer be a key training complex, particularly as other bases improve their own training capabilities.

The reason I don’t think this is an operating missile base is because it lacks many of the features common to known operational bases like Sakkanmol and Kal-gol. Some of the features it lacks are:

• Jangjin lacks any perimeter fencing or obvious secured entrance other than the headquarters itself. 
• Jangjin lacks any dedicated air defense sites. All of the air defense positions in the area are there to protect the Jangjin Airbase (6 km away) which is home to Il-28 bombers and MiG-21 fighter jets.
• Jangjin lacks any underground facilities.
• Jangjin only has three buildings on site. This is not enough to house the thousands of soldiers, munitions, vehicle sheds, maintenance facilities, etc. seen at other bases.
• North Korea’s missile forces are arranged into three main belts: Tactical, Operational, and Strategic. The Tactical and Operational belts are for short- and medium-range ballistic missiles and are located nearest the DMZ. The Strategic Belt is located across the northern part of the country and is where their intercontinental ballistic missiles are deployed. Jangjin is located in the Strategic Belt but does not have any known ICBMs. However, this makes sense from a security standpoint, as the base is situated beyond the range limit of South Korea’s operational missile arsenal at the time of the base’s construction.

If not a training base, another possibility (though unlikely) is that Jangjin is actually a decoy site to fool foreign intelligence agencies into thinking North Korea has a larger force than they really do. Of course, after being around for so many years and with very little mock operations occurring to fool foreign observers, such a decoy site would quickly be identified as such and it would no longer serve a useful purpose. 

North Korea does have up to 10 decoy surface-to-air missile batteries, but I am not aware of any fake ballistic missile sites in the country or anywhere else. 

If it is indeed a training facility, the Jangjin site fits within the logical development course of a missile program and it takes its place within a large network of related infrastructure that analysts are still trying to fully uncover.

I haven’t been able to find any public information about this facility and those whom I have asked about it were either unaware of its existence or only knew that “something” was in the area. One of the purposes of AccessDPRK is to provide what information can be found and then to ask the public to do their own digging and to work collaboratively so that ever more information becomes available. If you know anything more about this facility or think I have gotten something wrong, please share.

The Unique Buildings of North Korea's Missile Program

Despite all of the things we see and learn during North Korea's military parades and missile tests, only a fraction of the real story gets told (and often a fair amount of obfuscation is mixed in as well). Public knowledge of their ballistic missile program is still extremely limited though new discoveries do come to light.

Not every missile or vehicle is openly shown, and there are many deployed weapons systems and other equipment that have never been disclosed. Likewise, the infrastructure and training programs for their Strategic Rocket Force is largely unknown. And, North Korea has a habit of doing things just unusual enough as to baffle experts around the world.

In comparison to the United States and Russia/USSR, they test rockets and fire missiles far less often before beginning to mass produce them and place them into service. Their ability to indigenously manufacture the vehicles needed to transport and launch their missiles (especially the more modern versions) has often been viewed as lacking, but somehow, they end up with the equipment they need. Sometimes this is accomplished by converting large trucks from China and elsewhere, but it seems that their domestic capabilities may now surpass the limited capabilities usually described in public intelligence reports. 

Though this exact process is not fully understood, as WMD expert Melissa Hanham remarked in regard to the 11-axle transporter erector launcher (TEL) seen during the Workers' Party 75th anniversary parade in 2020, "It is also clear that they have built up their manufacturing sector to indigenously modify - and now potentially produce - their own missile launchers."

So, we are often left to dissect photos from state media, parse through the vague language of government and military officials, and use commercial satellite images to look for clues and try to learn what the DPRK doesn't want us to. That’s the purpose of this article, to use what is available to try and paint in some of the picture regarding North Korea’s TEL development.

Locations of the five extant TEL-cupola facilities.

One such little-known cog within North Korea's vast missile infrastructure are five (formerly six) unusual buildings that have been described as "clearstory cupolas". Their exact nature is not known, at least not publicly, but it is surmised that they play a role in both the development of new TEL designs and a role in the maintenance of deployed TELs, and in training their Strategic Rocket Force.

They take on two main designs, one is a modified section of roof of a larger, high-bay building and the other is a small building that is basically the modified roof section itself but placed on the ground as its own independent structure. 

The most well-known of these little-discussed structures is the Jonchon TEL Assembly Plant that was written about in 38 North's "That Ain't My Truck", in which the authors hunt down the location of this special building after it was first shown in a state propaganda film. 

Of the inventory of these formerly six (now five) buildings, two are located at known TEL/arms assembly factories, one was located at a missile-related facility, and three were built after 2011 at known missile operating bases stationing short range- and medium range- ballistic missiles.

The city of Jonchon has two of these facilities. The first is what was shown in the 2013 Korean Central TV program and discussed by 38 North. It is located at 40.645677° 126.432921°.

In 2004 the cupola structure was approx. 11 meters long by 6 meters wide.

By 2011 the cupola structure had been enlarged to ~20 meters long and 6-7 meters wide. Exact measurements can be difficult to acquire using Google Earth.

The following are models of the Jonchon TEL Facility.

This interior view shows not only the cupola but a KN-08 TEL with missile raised. Missile and TEL model by Frank Pabian and Tamara Patton; building model by Melissa Hanham, James Martin Center for Nonproliferation Studies. Used with permission.

The other Jonchon facility is locate a short 3.7 km south at the Mupyong-ni Arms Plant (40.612031° 126.426428°). 

In 2004, the cupola was 15 meters long.

As with the TEL assembly plant, the cupola was enlarged here, too. It was expanded to 20 m in length (also increasing its height), making it capable of handling newer, larger generations of missiles.

The Mupyong-ni Arms Plant was the site of a 2017 test of the Hwasong-14 ICBM. A monument was erected at the plant to commemorate the launch.

The other sites are as follows:

Sakkanmol Missile Base (38.582871° 126.082998°). Unlike the two in Jonchon, the Sakkanmol facility is a stand-alone cupola structure, not attached to any larger building. It was constructed sometime between 2011 and 2013. 

The simply built structure is 16-17 m long by 7.5-8 m wide.

Sakkanmol is home to MAZ-543 TELs which carries the Hwasong-5 short-range ballistic missile, and the base is capable of deploying the Hwasong-6 and could be modernized to accommodate larger missiles. According to Beyond Parallel, the base has 9 to 18 TELs/MELs stationed at it.

Kal-gol Missile Base (38.684702° 126.720857°).

Kal-gol's cupola building was constructed in 2012. It consists of a 31 m long building with a cupola structure that is 14.5 m long by 3 m wide. Like Sakkanmol, it is a short-, medium-range ballistic missile base and has the Hwasong-6 and Hwasong-9 missiles deployed there.

Beyond Parallel's 2020 report on the base noted the existence of the clearstory cupola facility and supports the idea that they are used for TEL/MEL maintenance and training purposes.

The report also stated that the arched clearstory, "reaches a height of approximately 13-15 meters. This height allows for the elevation of a Hwasong-5/-6 missile (and potentially the 13.5-meter-long Hwasong-9 (Scud-ER) depending upon the level of the floor) on a TEL or MEL for both training (especially during the harsh winter months) and maintenance. The latter would ease the burden of depot-level maintenance requiring a TEL or MEL having to be sent back to the factory for repairs or upgrades and reduces the length of time that a launcher is away from its parent unit. However, this clearstory building is too small for larger missile systems such as the Hwasong-12, -14, and -15."

The last existing facility is at the Kumchon-ni missile base (38.964928° 127.597185°).

The TEL building at Kumchon-ni was constructed in mid-to-late 2012 and is 18-19 m long by 8-9 m wide. A set of adjacent barracks were joined into a single building at the same time. Unlike the other TEL structures, this one was built against a hillside, where the others are in more open terrain. 

However, like Sakkanmol and Kal-gol, Kumchon-ni is within the "tactical belt" of North Korea's ballistic missile base network. These bases house short- and medium-range ballistic missiles and would be involved in any first-strike against South Korea or even parts of Japan, as well as targeting US forces within South Korea. They would also be among the first locations to be attacked, and so ensuring proper training and that operational readiness is maintained is of the utmost importance. 

Generally, these buildings are large enough to accommodate TELs/MELs for the KN-02, KN-23, KN-24, KN-25, Hwasong-5, -6, -7, and -9, and possibly the Hwasong-10 and Pukkuksong-2. (See also: Missiles of North Korea by CSIS)

A sixth facility used to exist until it was demolished in 2020. Located much farther north than the missile operating bases mentioned, near the town of Sinhung, is a missile-related complex at 40.260594° 127.490231°.

The structure was 9-10 m wide and 20 m long.

Abutting a hillside, the Sinhung TEL structure was demolished ca. Feb. 2020.

Only an empty foundation remains today. However, at roughly the same time that the site was being demolished, another building was being constructed about 1.1 km west.

This new building is ~67 m long by 17 m wide and has a large hole in the roof that's 25 m long by 5 m wide. This could be a new larger cupola facility under construction, like the two in Jonchon, and would be used to develop larger TELs, as the opening for the clearstory section is bigger than at either Jonchon facility. Of course, only updated imagery of the completed building will give any certainty to this, but it does seem coincidental and the fact the unfinished building has a specific shaped hole in the roof suggests that this could be the case.

As we have seen, these facilities were either enlarged or built in and around 2011/2012, this coincides with Kim Jong Un's orders after assuming power that realistic training be instituted and operational readiness improved. The development of future (post-2011) generations and variations of ballistic missiles was also high on Kim Jong Un's agenda. This desire may be reflected in the proliferation of these structures as well - to facilitate newer systems as they are tested and their deployability ascertained.

Having a multi-purpose building such as these, where one can maintain various equipment, train on their use, and even modify them on the fly, would be greatly valuable to a cash-strapped country. These facilities, in combination with other purpose-built training facilities, lets us know that North Korea is serious about creating an effective missile force with the means to launch from any point in the country while maintaining the usefulness/survivability of their TELs.

Lastly, the particular nature and design of these clearstory cupola structures appear to make them unique to North Korea, as other experts have told me they weren't aware of any other country using buildings with this design in their missile programs.

It will take more research before their full purpose is known and how they interconnect with the rest of Pyongyang's missile program is understood, but at least we have a baseline of observations showing their locations, times of construction, and other important information that helps to build the picture.

The Current State of North Korea’s Satellite and Missile Facilities

Over the decades, North Korea has decentralized its satellite and missile launching facilities across its territory. One obvious benefit to this is security but it is done at the cost of efficiency. The more facilities one has, the more resources are necessary to maintain and upgrade them. It may even become necessary to neglect or demolish a site in favor of improving more important ones. Pyongyang seems to have learned this lesson and placed some sites in caretaker status, demolished others, and concentrated resources to support their core infrastructure.

In this article, I will examine the current state of the country’s launch and testing facilities and detail a few important changes that have happened under Kim Jong Un, who has overseen a greater number of missile tests than his predecessors combined.

While North Korea has a history of launching missiles from a range of locations (factories, airfields, and even along highways), the country does have a robust set of dedicated launching and testing facilities.

Currently, the country has two satellite launch sites, three rocket engine test facilities, a general launch facility, and two former sites that have been decommissioned in recent years. Within Pyongyang, two known tracking and control centers also exist.

Satellite Launch Sites

While all countries have the right to peaceful space exploration, the development of rocket engines to carry satellites or astronauts necessitates the development of ballistic technology. Indeed, this has been a concern of other nations regarding the development of private space exploration. North Korea’s official protests that their space program is solely peaceful have never been taken seriously by the West and even their own propaganda has occasionally betrayed the rouse. Most recently, the purpose of the December 2019 engine tests at the Sohae Satellite Launch Station have been described by state media as “bolstering up the reliable strategic nuclear deterrent of the Democratic People’s Republic of Korea”.

Located on the western seaboard, initial construction activity at Sohae (also known as Tongch'ang) was first noticed in the early 1990s and was largely completed by 2011. The first test occurred on April 13, 2012, with the failed launch of the Kwangmyŏngsŏng-3 earth observation satellite.

Improvements to the site continued to be made over the years including new administrative and observation facilities, an upgraded rail station, and even the establishment of an outer perimeter fence that encompasses the original complex and its inner perimeter. In terms of recent activity, there are three primary examples.

The first occurred in 2018. As a result of the first US-DPRK summit that was held in Singapore, North Korea began dismantling key structures. However, rapprochement didn’t last long and in March 2019 the second change happened, the launch pad structures began to be rebuilt. The third change came with the end of 2019 and underlined the continued importance of Sohae, as two rocket engine tests were carried out.

The county’s second satellite launch station, on the other hand, has largely remained in caretaker status since 2013.

Tonghae Satellite Launch Station (also known as Musudan-ri) is in North Hamgyong Province along the east coast. Considerably smaller, Tonghae’s construction started in the 1980s and was originally used in the development of early generation Scud missiles. In 1998, North Korea claimed to have launched a Kwangmyŏngsŏng-1 satellite from Tonghae, however, no orbital object was ever located or tracked by outside observers.

Another failed satellite launch attempt happened in 2009. In 2012, one of the last major additions to the site was constructed. The site, which has yet to be positively identified, is either a test facility or possible missile silo. However, despite initial progress, it was never completed. The most recent Google Earth imagery shows that it may actually be in the process of demolition.

Much of the trench covering has been removed and the control building has been torn down.

By November 2019, the covering had been partially removed and the control building demolished |Photo: Google Earth

Tonghae’s launch pad appears to be abandoned and is overgrown, while activity at the engine test stand and assembly building remains minimal. In fact, the grounds of the assembly building have been used for crop harvesting activities.

The original launch control building, tracking station, and the “new” control building (construction finished ca. 2015) have all seen little activity and signs of minor disrepair are visible. The Horizontal Processing Building has never been completed, despite construction starting in 2012.

Tonghae’s situation may be the result of the regime’s focus on launching satellites at Sohae with its superior facilities, testing missiles on mobile platforms, and keeping engine test stands near other required infrastructure, whereas Tonghae sits miles away from manufacturing and fuel production facilities. Tonghae’s future use seems rather bleak.

Rocket Engine Test Facilities

Beyond the engine testing facilities within both satellite stations are three additional test sites: at the Tae-sung missile factory (Pyongyang), the Magunpo solid-fuel engine test site (near Hamhung), and the Sinpo engine test site.

The Tae-sung rocket engine test stand as seen after a 2016 modernization program |Photo: Google Earth

The vertical test stand at Tae-sung (also called Chamjin) is located within the Tae-sung Missile Factory complex in Chollima, Pyongyang. Though the fairly rudimentary site can test engines for Scud and Nodong missiles, it underwent a period of general inactivity from 2006 to 2016. In 2016 the facilities were modernized, and a nose cone test was carried out. This suggests that testing larger engines may no longer be feasible (or necessary as other purpose-built sites exist) but that the site can still play a role in developing other aspects of ballistic missile technology.

Magunpo engine testing facility |Photo: Google Earth

Magunpo is one of North Korea’s newest testing sites (along with Sinpo). Vertical and horizontal test stands were constructed between 2013 and 2014. It also lies a mere 3 km from the No. 17 Explosives Factory in Hungnam where solid rocket propellant is produced. Since its construction, multiple tests have been carried out (as well as the launching of several missiles from the nearby Yongpo airfield to the southwest). Magunpo remains an important cog in North Korea’s missile program as it is currently the largest such site in the country.

Sinpo engine test stand |Photo: Google Earth

Within the city of Sinpo and including the nearby Mayang Island lies a key submarine base and is where most of the development of submarine launched ballistic missiles (SLBM) occurs. Initial work on the land-based test stand began in 2012 and supports “both the development of the Pukguksong-1 (KN-11) SLBM and SINPO-class SSBA’s missile launch systems,” according to Joseph Bermudez. There have been several “ejection tests” at the site as well as tests carried out on sea-based, submersible barges. The most recent barge-based test was of the Pukguksong-3 (KN-28) which was conducted on October 2, 2019.

Work at the submarine base has been ongoing and, according to 38 North, the use of Synthetic Aperture Radar (SAR) "revealed the presence of the North Korean SINPO-class experimental ballistic missile submarine (SSBA) and its submersible test stand barge positioned beneath a recently constructed, dockside awning designed to conceal and environmentally protect these vessels.” 

This is strong evidence that the development of SLBMs is a primary focus of the regime.

Hodo Launch Site

The Hodo Launch Site is a dedicated missile launch facility that lies on the Hodo Peninsula, north of Wonsan. The area has been used for artillery training since the 1960s but within this decade the training area has been increasingly used for long-range artillery and ballistic missile testing. Concrete launch pads, a dock, and other support buildings were constructed beginning in 2014.

Two launch pads were constructed at the relatively close-by Wonsan-Kalma International Airport in 2016 and several tests were carried out there, however, the subsequent construction of resorts and hotels along the same beach meant that those launch sites were demolished. Since then, activity at Hodo has greatly increased with several tests happening in 2019 including a test on May 4, 2019 and two short-range missile tests occurring in July.

Decommissioned Launch Sites

The first decommissioned launch site in recent history was the aforementioned site at Wonsan. Those two pads were the location of several high-profile launches including a Hwasong-10 launch which Kim Jong Un himself oversaw. The extremely basic facility was demolished for expediency as Wonsan was about to undergo an enormous construction project to build beach resorts. The upgraded facilities at nearby Hodo also meant that Wonsan became redundant.

Perhaps the most significant change happened at the Iha-ri military driver training base in North Pyongan Province. Between 2016 and 2017 a vertical engine test stand was constructed at the base. It was only used once, as a canister-launched ballistic missile ejection test for the Pukguksong-2 (KN-15) before being demolished in mid-2018 as part of Kim Jong Un’s April 2018 announcement that they would suspend future ballistic missile tests. The base has since been returned to its original purpose.

Control Centers

Pyongyang is host to the country’s central missile and satellite control centers.

The General Rocket Control Center is located within the Second Academy of Natural Sciences (also known as the Academy of Defense Science or the Sanum-dong missile factory) in northern Pyongyang. It is responsible for tracking and other activities related to the testing of ballistic missiles and was constructed sometime between 2001 and 2005. The facility has remained largely unchanged except for a new hexagonal building that was constructed in 2016. The Academy lies adjacent to the Kim Jong Un National Defense University which also plays a role in the development of missile technology.

The General Satellite Control Center is the control center of the National Aerospace Development Administration. The modern-looking complex was constructed near central Pyongyang along the Pothong River between 2014-2015. It handles satellite launches and tracking. An expansion of the facility began in 2017 with multiple large buildings being added to the complex. Construction at the site has carried on well into 2019. The exact purpose of these new buildings is unknown, but it is possible that they may be research facilities and will also provide museum space.

Conclusion

While some facilities may have been shuttered or demolished, the core of North Korea’s testing infrastructure and their ability to research and to construct missiles and launch vehicles remain undiminished. Pyongyang’s insistence that the recent Sohae tests were part of their nuclear deterrence, and their ongoing work toward developing SLBMs at their Sinpo facilities, clearly demonstrate the regime’s intentions. The question becomes, will the international community listen to what North Korea is broadcasting with the current state of their testing facilities?

Missile Bases & Major Underground Sites

North Korea is perhaps the most militarized country in history. As a country roughly the size of the US state of Pennsylvania, it has literally thousands of distinct military sites: air defense, training bases, coastal artillery batteries, airbases, missile sites, tunnels, and much more. Because of the country's nuclear program, their missile bases receive a lot of attention. However, there is still a lot that is unknown about these sites, in part, because North Korea has only officially acknowledged a handful of them (and often just in vague terms).

The satellite facilities at Sohae, Tonghae and the Chiha-ri missile base are fairly well known, but the good folks over at Beyond Parallel (part of the Center for Strategic International Studies) estimate there may be as many as 20 undeclared ballistic missile bases and related support facilities. The 2017 release of "Phase II" of the AccessDPRK mapping project listed over 9,500 military points of interest, and since then, I have begun work on the next part of the map which now includes an additional 1,500 military sites. Using this unpublished version, I decided to see what likely missile bases and large underground facilities exist in the country. (These stand-alone underground facilities are something Beyond Parallel isn't looking at.)

After going through every identified military base, tunnel, underground facility (UGF), known and suspected missile base, and other sites, I was able to locate 19 known and possible ballistic missile bases, the two satellite launch stations, and 39 large UGFs that are separate from the missile bases.


North Korea considered the creation of a ballistic missile program soon after the Korean War and it became an official goal as early as 1965, with Kim Il Sung saying the country needed to have rockets that could fire as far as Japan. From then until the early 1980s, the regime laid the foundations of the program including the acquisition of Soviet and Egyptian technology. In 1984 they were able to test their first indigenously produced missile which was a variation of the SCUD-B.

The height of their missile program came with the first internationally verified successful orbital insertion of a satellite into space in 2012, the Kwangmyŏngsŏng-3 Unit 2, followed by the 2017 test of the Hwasong-15 missile which can reach nearly all of the United States.

The vast size of North Korea's missile program infrastructure (dozens of locations in a country the size of Pennsylvania) helps to ensure that they can continue to carry out attacks if one or several bases are destroyed during a war. It also makes it all the more difficult for Western powers to keep track of the movement of weapons and equipment.

North Korea's ballistic missiles and ranges. Image from the Center for Strategic International Studies. 

By 2017 the country was thought to have around 900 short-range missiles, though that figure may have grown to 1,000+ with the apparent development of a North Korea-produced clone of the Russian Iskander missile. (As well as from the continued production of known missile systems.)

• Short-range missile are typically defined as having a range of 1,000 km (620 miles) or less. Examples include the KN-02, Hwasong-6, and the aforementioned Iskander clone.
• Medium-range missiles have a range of 1,000-3,000 km (620-1,860 mi). Examples include the Rodong-1 and Pukkusong-2 (KN-15). North Korea likely has 500 or fewer of these missiles.
• Intermediate-range missiles can reach 3,000-5,500 km (1,864-3,418 mi). An example is the Hwasong-12. There are likely fewer than 250 IRMBs.
• ICMBs (intercontinental ballistic missiles) have a range exceeding 5,500 km (3,400 mi). North Korea's Hwasong-15 is their latest developed ICBM. There are probably fewer than 75 operational missiles in this category.

The country's missile bases are divided into three main "belts". They are, with increasing distance away from the DMZ the, "tactical belt", "operational belt", and "strategic belt". The different belts reflect the types of missiles deployed at each base, with the strategic belt holding long-range missiles (this includes the submarine base at Mayang) and the tactical belt being the site of shorter-range missiles aimed at the DMZ, Seoul, and other important South Korean sites.

Pyongyang's missile program is under the control of the Korean People's Army (KPA) Strategic Forces and the construction of the bases is done by KPA Unit No. 583 (the Military Construction Bureau). Substantial construction began for many of the bases in the late 1980s to mid-1990s, and construction at all sites had either already began or was scaled up by the 2000s. Several ballistic missile bases, such as Chiha-ri and Yusang-ni, have had upgrades since Kim Jong Un came to power.

A note on naming. Unless a name has been given in an official North Korean or US-ROK alliance intelligence source, all of the locations talked about in this article are otherwise named for the nearest populated place as listed by OpenStreetMap. A lack of standard naming has led to confusion for years, but that's one thing this article seeks to remedy. And, instead of simply saying "a base in Chagang Province" or "by Kimchon-ni" (when there are multiple villages with the same name), this article will list the base's exact coordinates.

These twenty-one main facilities occupy approx. 362 square kilometers of territory. Despite my best efforts, I wasn't able to positively identify the To'gol base (allegedly in Pyongsan County) or the Kittaeryong base (in Anbyon County).

Within the "tactical belt" are:

1. Chiha-ri - Coordinates are: 38°36'10.63"N 126°44'12.20"E
2. Kal-gol - Coordinates are: 38°40'3.15"N 126°44'49.97"E
3. Kumchon-ni - Coordinates are: 38°57'54.14"N 127°36'8.48"E. Kumchon-ni has been detailed by Beyond Parallel.
4. Sakkanmol - Coordinates are: 38°34'59.81"N 126° 6'29.91"E. Sakkanmol has been detailed by Beyond Parallel.
5. Sing'ye - Coordinates are: 38°38'24.31"N 126°40'48.26"E. Sing'ye is one of the smallest missile bases in the country. It may also be the source name for the Hwansong-class of missiles as a nearby village is named Hwasong, and the base was constructed early on.
6. Suthae-ri - Coordinates are: 38°22'51.67"N 127°29'0.55"E. Suthae-ri is a possible base and hasn't been mentioned in any media that I could find. At less than 10 km from South Korean territory, it would be the closest ballistic missile base to the DMZ. The base doesn't have the "drive thru" bunkers that many other known bases have, but it does have a large and expanding underground facility and several bunkers of other types.

Chiha-ri, Kal-gol, and Sing'ye are all within 5 km of each other, which would lead me to believe that they are connected in some way; perhaps in mutual-supporting roles.

Within the "operational belt" are:

1. Hodo - Coordinates are: 39°24'30.31"N 127°32'5.63"E. The Hodo base is very small and is more for testing missiles than as an operating base during conflict. Hodo seems to have replaced the beaches at Wonsan for testing sort-range missiles, as the site at Wonsan is now a cluster of hotels.
2. Hwajil-li - Coordinates are: 39°11'52.58"N 125°23'56.93"E. Hwajil-li is listed by the Nuclear Threat Initiative as a missile base that was constructed in the 1980s. Current satellite imagery doesn't show anything that would suggest the site is currently used as a missile base. A basic air defense battery and associated facilities is all that exists today.
3. Ongpyong - Coordinates are: 39°19'33.69"N 127°19'50.68"E. It is a smaller base and its facilities may be dispersed throughout a larger area. There are ongoing questions about the site's true purpose, and it may not be a ballistic missile base but rather a support facility for region air defense sites. 

4. Sil-li - Coordinates are: 39°10'49.68"N 125°39'48.84"E. Sil-li is located next to the Pyongyang-Sunan International Airport and is a "ballistic missile support facility", which is not the same as an "operational ballistic missile base". It was constructed from 2016-2020, and has been detailed by Beyond Parallel. 
5. Singsong-ri - Coordinates are: 39°21'32.23"N 125°45'49.57"E. Singsong-ri is a possible base. Like Suthae-ri, it doesn't fit the design of a lot of other known bases, but it does have three underground entrances which run deep into a mountain. If it is indeed a base, it's likely used to store missiles and equipment.
6. Yusang-ni - Coordinates are: 39°26'51.58"N 126°15'30.33"E. Yusang-ni has been detailed by Beyond Parallel.

On average, the land area used by these bases is smaller than bases in the other two belts.

Within the "strategic belt" are:
This belt includes the country's two satellite launching stations as they have played a role in the development of ballistic missile technology and could be used as launching sites.

1. Hoejung-ni - Coordinates are: 41°22'21.64"N 126°54'46.14"E. Hoejung-ni is one of the newest missile bases to be constructed. It is only a few kilometers from the base at Yeongjo-ri
2. Kusong-ri (alleged) - Coordinates are: 39°59'51.22"N 124°34'16.80"E. According to Jane's/IHS, this surface-to-air missile base may also house some Nodong missiles; however, this has never been conclusively demonstrated and it is likely only an air defense base based on the most recent satellite imagery.
3. Riman-ri (Yongnim) - It is the largest base by area and covers approx. 72 sq. km. Coordinates are: 40°29'2.94"N 126°30'1.65"E
4. Sangnam-ri - Coordinates are: 40°50'20.20"N 128°32'35.82"E. Sangnam-ri has been detailed by Beyond Parallel.
5. Sinpo-Mayang - Coordinates are: 39°59'42.09"N 128°11'43.98"E. Sinpo houses part of a large submarine base (the other half being on Mayang Island) and has a missile test stand. The base is where North Korea is developing their submarine launched ballistic missiles. The base is not an operational ballistic missile base where missiles would be fired from, but I have included it for its role in the development of SLBMs and the fact that any future SLBM-capable submarines would be based at Sinpo-Mayang.
6. Sino-ri - Coordinates are: 39°38'57.32"N 125°21'36.37"E. Sino-ri has been detailed by Beyond Parallel.
7. Sohae Satellite Launch Center - Coordinates are: 39°40'6.88"N 124°42'30.44"E
8. Taegwan - Coordinates are: 40°18'34.10"N 125°16'17.02"E
9. Tonghae Satellite Launch Center - Coordinates are: 40°52'13.09"N 129°38'34.10"E. My discovery of a missile test stand being constructed at the site was the basis of my very first #AccessDPRK post back in 2013.
10. Yeongjo-ri - Coordinates are: 41°19'44.56"N 127° 5'35.38"E. Once considered a nuclear site, Yeongjo-ri is actually a missile base.

The next area I want to explore is the collection of large underground facilities (UGFs).

As mentioned earlier, these UGFs are not part of any obvious missile base. Underground sites abound in North Korea and serve as active and reserve storage sites for weapons, equipment, food, and other supplies, and they allow for artillery to be fired and then rolled back into the tunnel for protection against counter strike. There has been a lot of speculation about the number of tunnels and underground sites within the country with some estimates going as high as 100,000. Based on the work for AccessDPRK, the real figure is much closer to 1,000 sites (some may have multiple entrances, but they're part of a single facility). Most of them are small and some are used as underground factories. But there are a few dozen (39 to be exact) which are much larger than any of the others (excluding underground industrial sites).

Some of them are placed at military bases and consist of a single complex while others exist as clusters, especially in Pyongyang.

There are four UGFs in Chagang Province.
1. Oil-rodongjagu UGF - 40°59'53.82"N 126°46'51.12"E
2. Janghang UGF - 40°57'32.66"N 126°41'9.98"E
3. Kanggye-Puji UGF - 40°53'12.75"N 126°38'4.45"E
4. Jonchon UGF - 40°32'49.08"N 126°19'48.21"E. This facility is across from the Riman-ri (Yongnim) missile base and so may be connected to it in some way.

There are three UGFs in S. Hamgyong Province.
1. Toksan UGF - 40° 1'52.84"N 127°35'48.28"E
2. Sinphung UGF - 39°58'7.64"N 127°50'17.89"E
3. Songhung UGF - 39°22'54.97"N 127°10'43.71"E

There are five UGFs in Kangwon Province.
1. Chongdu-ri UGF - 38°22'2.71"N 128° 2'20.19"E
2. Wondong-ri UGF - 38°24'51.14"N 127°41'59.76"E
3. Konsol-li UGF - 38°29'30.47"N 127° 0'7.53"E. The UGF here is part of a new military base that was constructed in 2016-2017.
4. Jisang-ri UGF - 38°34'44.13"N 126°44'5.59"E
5. Kubong-ri UGF - 38°37'44.89"N 126°43'15.55"E

There are four UGFs in N. Hwanghae Province.
1. Phyongwon UGF - 38°46'42.16"N 126°27'47.77"E. This has a very large UGF and might actually be part of their missile infrastructure.
2. Taephyong UGF - 38°26'5.60"N 126°20'37.53"E
3. Misan-ri (Kyongje-dong) - 38°34'41.50"N 125°56'6.04"E. This is a set of two enormous bunkers that would serve as a hardened helicopter base during conflict.
4. Okhyon - 38°22'4.16"N 125°44'22.81"E

There are 23 UGFs in Pyongyang. Eleven of them are in three clusters. Each cluster will only get one set of coordinates.
1. Pyongyang Group 1 - 39° 5'58.09"N 125°49'48.07"E. There are three large tunnels/entrances that spread out in an east-west line approx. 1 km long.
2. Pyongyang Group 2 - 39°10'11.96"N 125°51'28.16"E. This is a set of five large tunnels that are along a valley between two sets of hills. From the coordinate given, a rectangle is formed by a line running 1.4 km west to east and then from that point, north to south for ~0.5 km.
3. Pyongyang Group 3 - 39° 5'54.07"N 125°57'1.50"E. This is a group of three tunnels that are all located within the same hill, encircling it.
4. Pyongyang Single UGF - 39° 6'43.85"N 125°58'24.30"E
5. Taedonggang Large UGF - 39°10'25.07"N 125°56'43.60"E
6. Taedonggang Smaller UGF - 39°10'31.77"N 125°56'46.76"E
7. Samdung UGF - 39° 1'32.28"N 126°12'56.77"E
8. Rodgon-ri UGF - 38°57'54.22"N 126° 2'27.51"E
9. Sangwon UGF - 38°49'39.49"N 126° 5'23.32"E
10. Chunghwa UGF - 38°52'28.51"N 125°48'23.32"E. This UGF is within the Air Defense & Combat Command HQ complex.
11. Sunwha UGF - 39° 0'52.08"N 125°36'15.03"E
12. Kanchong UGF - 38°51'34.16"N 125°33'15.48"E
13. Kangso 1 - 38°52'55.87"N 125°30'57.91"E
14. Kangso 2 - 38°52'46.98"N 125°31'48.32"E

Here are a few examples of these underground facilities.

Rockets and Runways

Kim Jong Un is well on his way to becoming the most prolific builder since his grandfather, Kim Il Sung. There are the new roads, the billions spent on construction projects in Pyongyang and in other major cities, modernizing airports and constructing new ones, and much more. Kim Jong Un has been busy as he enters his seventh year in power.

Those further changes to North Korea's military airbases and other runways, as well as the stunning advancement of their ballistic missile program makes it necessary for me to write, once more, about the ever-progressing nature of North Korea's military. There are three main areas of focus for this post. The first is the construction of multiple new aircraft parking revetments at new and older emergency runways. The second is the construction of more emergency runways. And the third deals with the possibility of the merging of North Korea's major airbases and ICBM program.

North Korea has 111 airports, airbases, heliports, emergency highway runways, and other landing strips. Particularly since 2016, nearly all of their emergency highway runways (straight sections of road that have been widened for use by aircraft in the event of a war) have had aircraft parking revetments constructed to augment each site. Additional basic runways have also had revetments constructed. In all, 15 airfields have had new revetments constructed. The number of revetments varies between one and four (most have three), but there is a grand total of 39 individual revetments which could support a combined 75 aircraft (at least) depending on type and parking arrangement.

It's important to note that not all of the satellite imagery of all of the different air facilities in North Korea has been updated to include either 2016 or 2017 imagery, so it's possible there are other sites that have had revetments constructed. I just can't yet see them.

Here are some examples of these sites. Click on any image to see an enlarged view.

Since my 2015 article on the North Korean Air Force and the changes that have happened under Kim Jong Un to the physical infrastructure of the Air Force and general aviation, at least three additional runways have been constructed.

Changdo, Kangwon Province (38.67993°, 127.72681°)

This runway is also approx. 3 miles (4.8 km) north of a military training base that underwent fairly substantial expansion in 2013.

Chongjin, North Hamgyong Province (41.80234°, 129.85480°)

This small auxiliary runway was constructed in early 2016.

Sunchon, South Pyongan Province (39.44058°, 126.03576°)

This runway is being constructed across from the large Sunchon Cement Factory. Curtis Melvin at North Korean Economy Watch believes that this will be a new 'executive' runway for use by Kim Jong Un and other high ranking officials. What makes it odd, in my mind, is the fact there are two large military airbases (and a helicopter base) within 12 miles (19 km) of this new runway - after all Sunchon is an important industrial city.
Perhaps the 30 minute drive was a bit too much for the Supreme Leader.

North Korea has a history of testing missiles from their airports, particularly at Wonsan (Kalama) and Pyongyang International. During the modernization and expansion of Wonsan, an observation facility was constructed as well as two concrete launch pads on the beach. And as you can see in the opening image of this article, Kim Jong Un observed the test of a Hwasong-12 ICBM from Pyongyang International. But unlike Wonsan, the Pyongyang launch was carried out on the bare ground.

Along the line of launch pads, there has been a curious development at 19 of North Korea's major air facilities. Starting in 2015 and extending into 2016 (such a busy year), twin squares of concrete began to pop up at these airbases. Unlike the small launch pads seen at Wonsan or other sites, which are approx. 60 x 80 feet (18 x 24 meters), these new pads are each roughly 165 x 140 feet (50 x 43 meters). All but two airbases have two of these pads, one at each end and directly in line with the runway's path, but not connected to it. The other two just have a single pad. Most are made of concrete, but a few are simply areas of cleared land and compacted dirt.

My initial thought was that these were helipads, but they're much larger than most helipads in the country. Additionally, these are military bases and space already exists for helicopters. Furthermore, Pukchang Airbase (near Sunchon) has an adjacent helibase with dozens of helicopters stationed there, yet the main airbase also has these new pads. Use of these sites for helicopters is also lessened because the pads aren't directly connected to the runway and are separated from them by around 170 feet (51 m).

I am not an aviation expert, but I have explored the globe via Google Earth (and been to a few airports) and I have yet to see this layout anywhere else. My second thought then became, what if these are actually meant to allow rapid deployment of various missile systems? (Their size would accommodate everything in North Korea's arsenal.) I have asked for the input of others but wasn't able to get much more than "that's plausible", with no other firm alternative explanations. So perhaps North Korea now has 36 new ICBM launching sites, or maybe it's something else entirely. The fact these things popped up across the country, basically overnight, are fairly uniform in size, and are only located at major military sites, impels me to at least bring attention to them.


These two images shows the pad area at Kaechon Airbase before and after construction.

This next set of images is just a sample of different bases with the pads.

Here is the list of coordinates for each of the airbases with these pads.

Toksan: 39.98743°, 127.60276°
Uiju: 40.15111°, 124.49965°


My ego isn't so fragile that I can't handle correction. If you think (or know) I have misidentified these sites or can offer a plausible alternative, please let me know!
