North Korea's Underground Navy: A Review

Many countries have underground facilities for their navies. Places to protect submarines, places to defend against surprise or nuclear attacks, underground storage, places that have all kinds of purposes.

One large example was the Soviet base in Balaklava, Crimea. China currently maintains at least six underground submarine bases. The United States has an enormous underground fuel storage site in Hawaii.

North Korea is no different.

North Korea has a tremendous amount of experience digging tunnels. I have found hundreds of tunnels across the country, hundreds of artillery sites that pop out of tunnels, scores of underground factories, and quite a few underground naval sites.

Bounded on two sides by the ocean and with 2,495 km of coastline, the Korean People's Navy has a strength of 60,000 men and over 800 vessels, making it one of the largest navies in the world in terms of vessel numbers. And while most of their naval technologies are decades behind the West, Kim Jong Un has been focusing on modernizing the fleet. Furthermore, what they lack in technology they can make up (some of that gap) by sheer numbers.

North Korea has 70-80 submarines, which places them on par with the United States (based on numbers) and far outpaces South Korea. Their navy has been able to inflict substantial damage in attacks like the Second Battle of Yeonpyeong in 2002.

And so, it makes sense to marry navy and tunnel together. Underground naval bases provide safety in the event of attack and secrecy to develop, arm, refuel, and launch attacks. Having multiple sites also makes it more difficult for an attacking country to quickly knock out North Korea's navy.

The country has 13 identified underground naval sites. Some can accommodate submarines but most currently serve various types of surface ships. Interestingly, North Korea's main submarine base for the Sea of Japan (East Sea), which is based on Mayang Island, lacks any apparent underground facilities.

The facilities range from simple tunnels to more complex facilities that are accessed from the sea and cover a large footprint.

Starting with the Yellow Sea (West Sea) bases:

Taewha-do Underground Base: 39°25'59.69"N 124°37'2.39"E

Taewha-do is on an island (the -do suffix means island) and consists of a small underground facility and a turntable to enable vessels to be moved around the base on a short rail system. There is only a single dual entrance/exit point to the underground facility (UGF) but the island's size could theoretically accommodate an enormous UGF inside. However, it only appears to house small patrol boats and the island garrison is no larger than battalion sized.

Very little information about the base is publicly available and most of the information that does exist relates to a series of small military actions during the Korean War, before the UGF was construction. The island rises steeply out of the ocean and can provide up to 600 feet of solid rock on top of the UGF, giving it excellent protection.

Sok-do is not necessarily an underground base but rather it is a set of four hardened pens that allow craft to be protected. Located at 38°38'7.33"N 125° 0'26.27"E, it doesn't appear to be in use. It lies just 5 km from Pip'a-got, which is a primary naval base.

Pip'a-got is the largest naval base immediately outside of the West Sea Barrage which cuts off direct access to the Taedong River and Pyongyang.

Pip'a-got naval base.

The base consists of a large protected harbor (created by a set of breakwaters), hundreds of buildings, and seven distinct ship handling sites (dry docks, main harbor, UGF, etc). It covers approx. 5 square kilometers.

The underground component consists of a 600-meter long tunnel that connects a turntable (that can take ships from a slip and bring them to the tunnel entrance) to an exit that enters directly into the sea, bypassing the large seawalls.

The tunnel could include other facilities like fueling, loading weapons, and repair, but the interior layout is not known. The hill it cuts beneath rises from ~90 feet at the turntable to a maximum height of ~250 feet along the path of the tunnel.

Sunwi-do & Sagot (Ryongho) Bases
Sunwi-do has a small base at the far northeast end of the island. It is across from the larger Sagot base on Ryongho Island 4 km to the north. Both bases are in South Hwanghae Province are the southernmost underground naval facilities on the west coast. The base at Sunwi-do lies a 31 km from the South Korean island of Yeongpyeong.

The base on Sunwi Island, 37°46'11.59"N 125°20'21.45"E

At its height, the island provides ~180 feet of rock over the Sunwi tunnel which runs for 250 meters.
North Korea has several classes of patrol boats and Sunwi seems to be a base for them. In the imagery provided by Google Earth, at no time has there been more than 13 ships and none over ~28 meters in length.

In this image of Ryongho, four classes of ship can be seen. Upwards of 36 ships have been seen at Ryongho but some may have actually been small fishing vessels along with the military craft.

Sagot base is split between two main facilities. One is at the town of Sagot, on the mainland 1.8 km to the north, and the second is the UGF on Ryongho Island (37°48'17.24"N 125°21'9.58"E).
A direct line from the Ryongho entrance to the exit runs 290 meters but the full tunnel path isn't a straight line. It is likely at least 365 meters in total length. Between 150 and 250 feet of rock sits above the site, depending on location.

The exit has apparently silted up and cannot be used as a direct exit point for sailing into the sea. Any vessel must be towed down the "hump" from the UGF exit point to the water. Why this hasn't been corrected would only be speculation, but it has been the case since at least 2004.

NK-01 antiship cruise missiles (a local variant of the Soviet P-15 Termit (aka Styx) are believed to be deployed at the base.

Along the northeast edge of the island is a series of small tunnels for terrestrial vehicles and other equipment. This is a common feature found at many bases across the country.

East Sea (Sea of Japan) Bases

Puam-dong is the first base on the east coast. (Going north to south, as I did for the Yellow Sea bases.) Located at 41°19'17.15"N 129°46'4.71"E it is a primary navy base and has a large harbor protected by ~470 meters of breakwaters.

The base has been called a submarine base (and some of its features support that conclusion) but no submarines are visible in the available imagery. Other vessels stationed at the base include the Sohung-class PTG (guided missile patrol boat). This has been a key base for them since at least the 1980s.

Puam-dong is divided into two sections because of a hill in the middle of the base. The main section has headquarter facilities, barracks, and other buildings. The second section (to the south) is for maintenance.

The tunnel runs for at least 425 meters and the hill provides ~270 feet of rock above. The base also has a small underground storage facility higher in the hills at 41°20'12.02"N 129°45'24.94"E.

Cha'ho is a major submarine base located at 40°12'18.28"N 128°38'59.31"E in S. Hamgyong province. Including the harbor, it covers approx. 7.7 square kilometers.

Development of Cha-ho began in 1961 and it was transformed from a small base for patrol craft to a major submarine facility. By 1968 the underground portion was under construction. Unlike many other bases, it has rail access.

Unlike land-based underground facilities, where large piles of debris can be seen and analyzed to yield the approximate volume of the UGF, sea-based sites tend to lack any visible debris (since it can just be dumped under water) making it almost impossible to determine its size or layout using traditional methods. (Technology does exist that can shed light on the internal nature of the site using special techniques, but those are beyond the reach of most.)

However, at least a portion of the quay positioned between the entrances of the UGF may be made up of excavated debris based on a review of declassified images.

Taking the curved shape into account, the tunnel runs at least 330 meters and is protected by upwards of 200 feet of rock. I suspect that the main tunnel is placed farther back than I have it drawn, but that's why things are labeled "approximate".

Throughout the base Sang-O class (mini subs) and Romeo-class submarines can be seen. Romeo's are Chinese built, Soviet originated submarines that North Korea first acquired in 1973.

Ryoho-ri (Toejo-dong) Base is the location of the East Sea Fleet Command. It goes by several designations, Ryoho-ri, Yŏho-ri (an alternate spelling), and Toejo-dong (the name of the bay and also commonly used). Its location is 39°52'33.92"N 127°46'43.45"E.

As if signifying the base's importance, one of North Korea's many leadership residences is adjacent to the base. Ryoho is also serviced by rail.

The base doesn't appear to have any shipbuilding capabilities, but it does have a small repair facility for patrol boats. As mentioned, it is the headquarters for the East Sea Fleet and commands all of the bases and associated facilities along the east coast. One of the subordinate units at the base is KPA Unit 158.

The underground facility follows the same basic design as all the others. Its tunnel is ~315 meters long and is covered by roughly 200 feet of rock.

Samil-ri is a small UGF that consists of a single entry point. Located at 39°22'18.03"N 127°26'18.43"E it is on a small peninsula that's part of the much larger Munchon Naval Base.

Across from it on the other side of the peninsula (over 900 meters away) is a turntable but it doesn't appear to have been used in years and the images available on Google Earth make it difficult to confidently assert that there's a tunnel connecting the two points.

It's hard to gauge how active this site is, particularly since the turntable doesn't appear to be in use, but the wider Munchon area has been the focus of a large modernization and expansion program which has been ongoing since 2014. The Munchon-Wonsan region is an important military and industrial area, and various improvement projects have occurred there including the Kalma International Airport, Wonsan-Kalma tourist zone, and the nearby Hodo missile test facility.

Of note, various materials can be seen at the entrance site in recent images that could be used in a restoration project.

Sindo & Yodo island bases

Sindo is a small, narrow island in Yonghung Bay, off of Wonsan. It has a small underground site but unlike Samil-ri it definitely doesn't have an exit point. It is located at 39°13'18.11"N 127°31'10.04"E and would have a maximum length of 85 meters (based on the particulars of the island). The island's garrison seems to be geared toward operating coastal defense artillery and is located nearly a kilometer to the east.

The Yodo island site is located 8.7 km east of the Sindo site. Like Sindo, it doesn't have a second entry/exit point, but it does have a turntable. This allows approx. 8 vessels to sit on the beach and then individually brought into the tunnel for servicing and then moved back out and onto the "holding yard".

If you look closely at the image, you can see a vessel halfway in (or out) of the tunnel entrance.

Yodo has a much larger garrison and even has a small grass runway that extends for 660 meters (although a dirt path cuts across it near the southern end). The naval tunnel may run for 180 meters into the hill to reach 140-150 feet of rock depth. Directly across is a hardened coastal artillery battery and those tend to have small tunnels connecting them to the outside. If we assume the tunnel comes close to the battery, then the tunnel may run as much as 200-230 meters.

Namae Navy Base

Located at 38°48'9.76"N 128° 8'18.58"E Namae is a large navy base with a breakwater that creates 38 hectares of protected harbor. The northern end of the base contains the underground facility. Namae has the facilities available to service all of North Korea's surface fleet and may be able to dock submarines.

The entrance is approx. 20 meters in width and could be covered by as much as 200 feet of rock. There does appear to have been an exit point built, but the tunneling work was either never finished or there was some other problem. An exit structure was built but is in a state of disrepair.

By 2013 a hole had appeared in the roof of the possible exit structure and by 2019 the roof had collapsed entirely. Had the entire facility been completed, the tunnel would have run 515 meters and would make it the second longest confirmed tunnel after Pip'a-got.

Possible exit structure with collapsed roof.

The last of North Korea's underground navy sites is at Changjon, 38°43'59.96"N 128°12'45.45"E.

It's the southernmost naval facility on the east coast and lies a mere 18 km from the military demarcation line.

Changjon is divided into two sections. The northern section contains a large active navy base, the southern section (~1.8 km away) has the underground facility but it appears to have been abandoned. No military vessels can be seen in Google Earth images (which go back to 2005), and there is a civilian dock with a floating restaurant just a kilometer away. It's part of the Kumgang tourism system.

At the same time, a small naval unit is still directly connected to it and the base did serve as a "frontline base for North Korean submarines" before being suspended as part of the creation of the aforementioned tourist zone. However, Kim Jong Un has recently expressed a desire to enlarge the base, so this portion of it may become active again in the future.

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 18 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 main facilities occupy approx. 362.5 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.
4. 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.
5. 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 also houses some Nodong missiles.
3. Riman-ri (Yongnim) - 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.
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 - 38°34'41.50"N 125°56'6.04"E. This is a set of two enormous bunkers.
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
