Undeclared North Korea: Sinpung-dong Missile Operating Base - CSIS | Center for Strategic and International Studies
As featured in the Wall Street Journal “North Korea Has a Secret Long-Range Missile Base Near Chinese Border, Report Says” on August 20, 2025.
The Sinpung-dong (신풍동) Ballistic Missile Operating Base is located (40.316252 125.276505) in Taegwan-gun (대관군, Taegwan County), Pyongan-bukto (평안북도, North Pyongan Province), approximately 12 kilometers northeast of the city of Taegwan.
The base is 27 kilometers from the border with China, approximately 146 kilometers north-northwest of Pyongyang, and 340 kilometers northwest of Seoul. All satellite imagery from 2003 onwards indicates that the base is active and being well-maintained by North Korean standards. Significantly, this imagery also shows that the base has continued to be developed.
Sinpung-dong is part of North Korea’s strategic (or rear) missile belt, along with the missile operating bases at Hoejung-ni, Sangnam-ni , Yongjo-ri, and Yongnim . This missile belt is one component of a widely-dispersed nationwide hardened ballistic missile network subordinate to the approximately 10,000-person strong Strategic Force Strategic Force—the Korean People’s Army (KPA) organization responsible for all North Korea’s 15-20 undeclared ballistic missile bases, maintenance, support, missile storage, and warhead storage facilities .
The Sinpung-dong base and the other missile bases within the strategic ballistic missile belt represent the primary components of what is presumed to be North Korea’s evolving ballistic missile strategy, and its expanding strategic-level nuclear deterrence and strike capabilities. Taken together, the ballistic missiles deployed within the strategic belt pose a potential nuclear threat to East Asia and the continental United States.
Construction of the base began sometime around 2004 and was generally complete and operational by 2014. As with the other missile operating bases within the strategic ballistic missile belt, it is believed to have been built using specialized engineering troops from the KPA’s Military Construction Bureau. 1 This ten-year construction timeline, when taken in context with the construction of the other strategic ballistic missile belt’s missile bases, suggests a considerable level of North Korean developmental planning that is rarely appreciated outside the Korean Peninsula. There is an even chance that ongoing improvements since 2014 are related to a combination of ongoing IRBM and ICBM developments, basing requirements, and organizational developments.
North Korea is not known to have made any specific public references to the existence of the Sinpung-dong base or the KPA unit based here. Additionally, neither of their national designators is known. 2 As such, the provisional title of Sinpung-dong Missile Operating Base is derived from its location adjacent to the village of Sinpung-dong. Media reports over the years referring to a missile base at Changsong-gun, Paegun-dong, Paegun-tong, Paekun-dong, Sakju-gun (the county adjacent to Taegwan-gub), Sakju-up, Taegwan-gun, or Taegwan-up are most likely referring to the Sinpung-dong base. 3
Although the details concerning the precise model of ballistic missile deployed at the Sinpung-dong base have not been confirmed, it is believed that the unit based here is equipped with nuclear capable Hwasong-15, -18, or an as yet unknown intercontinental ballistic missiles (ICBM), their transporter-erector-launchers (TEL) or mobile-erector-launchers (MEL), and various support vehicles at the base. During times of crisis or war, these launchers and missiles will exit the base, meet special warhead storage/transportation units, and conduct launch operations from dispersed pre-surveyed sites. 4 If the two unique large earth-bermed support structures identified within the base serve as emergency launch sites, then warhead storage and maintenance units of necessity would deliver warheads to the launchers at the base before returning to their own base.
It is situated within an isolated narrow mountain valley that runs generally southwest to northeast on the southern slopes of Pugo-san (부거산, Pugo Mountain) and is bisected by a stream. The entire base is estimated to encompass approximately 22 square kilometers. As of July 2025, the base can be functionally divided into six general activities:
The overall layout and design of the Sinpung-dong Missile Operating Base is comparable to that of the Yongnim Missile Operating Base , as it is also dispersed within an isolated narrow wooded mountain valley with branch valleys. The main valley, beginning at the agricultural village of Sinpung-dong (신풍동), extends approximately 4.8 kilometers from southwest to northeast and features a stream that meanders along its center. To support movement across the stream throughout the base, three 5 to 7-meter-wide reinforced concrete deck bridges and a 6-meter-wide ford were built between 2018 and 2021. Four smaller valleys branch eastward from the main valley.
Satellite images from 1984 and 1995 show that the valley in which the base will later be built consisted of small agricultural and logging activities (often transitory), dispersed along the length of the main valley and on the adjacent slopes. As can be presently determined, construction of the base began sometime around 2005 and 2006, with two checkpoints positioned at the foot of the main valley at Sinpung-dong. 5
The entrances and checkpoints of the missile base are located in the southwest corner of the perimeter. Along with the entrances and checkpoints, the base is surrounded by at least seven remote compounds with small, cultivated fields. The positioning of these compounds suggests that they are likely to serve some security role. Aside from these compounds, numerous small and often transitory agricultural and forestry activities have been observed over the years at the upper ends and on the lower slopes of each of the valleys.

The Sinpung-dong Missile Operating Base is situated within a valley and the four smaller valleys that branch from the main valley. To ease readability in this report, the smaller branch valleys of the base are simply identified as branch #1 to #4, running from southwest to northeast.
The first entrance checkpoint leads approximately 4.8 kilometers northeast up the main valley. The second checkpoint leads approximately 1.7 kilometers east up branch valley #1. Moving up the main valley, the first checkpoint leads through housing for senior officers and dependents, a warehouse area, motor vehicle maintenance and storage facilities, agricultural support areas (including large greenhouses), the entrance to branch valley #2, and on to the headquarters and administration area at Wonha-ri. Approximately 86 senior officer housing structures were built between 2014 and 2017 as additions to the original 16 agricultural housing structures. The original motor vehicle maintenance and warehouse facility was built between 2006 and 2011 across several existing small agricultural warehouses.
Located approximately 1.7 kilometers up the primary valley is the headquarters and administration area (40.316236 125.276576). This area is similar in size and layout to those found at other missile operating bases. Construction began around 2004 and was completed by 2007. This area primarily consists of eight large buildings, including a cultural education hall (added between 2018 and 2019), headquarters, barracks, a second, but smaller, motor vehicle storage facility, and two formal circular gardens. 6 The buildings are arranged around a central parade ground or football pitch and a small memorial plaza. Since 2019, only minor modifications have been observed here, including the expansion of the motor vehicle maintenance and storage facility, the construction of a second smaller motor vehicle storage facility, and the construction of several small buildings.
Proceeding northeast from the headquarters area, there are additional barracks compounds, agricultural support areas, and the entrance to branch valley #3. Moving further northeast, there are at least two additional barracks areas, agricultural support areas, and the entrance to branch valley #4. Located at this entrance are the base’s two hardened drive-through missile checkout facilities (40.327571 125.297224 and 30.328032 125.298187) that were built on the east side of the valley between 2011 and 2014. These are used for missile arming, fueling, systems checkout, and maintenance operations.
Each checkout facility consists of a large, concrete-reinforced shelter cut into the side of the adjacent mountain, measuring approximately 35 meters by 17 meters, and is covered with soil and rocks, with vegetation planted on top. The length and size of the openings are of sufficient size to accommodate all known and likely planned KPA ballistic missile transporter-erector-launchers (TELs), mobile-erector-launchers (MELs), transporter-erectors (TEs), and missile support vehicles and equipment. As at other ballistic missile operating bases, North Korea has planted trees and bushes over the entrances to these hardened facilities to conceal them. The maturing vegetation makes it increasingly challenging to locate them using commercial satellite imagery except in winter months, when vegetation is sparse.
The main valley continues northeast from the hardened drive-through missile checkout facilities and entrance to branch valley #4. The two entrances to the base’s UGF are located here: one at the northern end of the main valley (40.330859 125.299040) and the other within branch valley #4 (40.328936 125.300770).
The construction of the UGF entrances at the Sinpung-dong base is unique compared to that of other ballistic missile operating bases. To accommodate both the steep terrain and mountain streams that seasonally flood, the two UGF entrances were built approximately 20 to 40 meters above the streams. This necessitated the use of terraced construction, featuring large ramps—likely utilizing much of the rock and gravel tailings excavated from the UGF—leading up to the entrances, with water tunnels beneath them to allow the stream to flow.
The openings for both entrances are approximately 5.5 meters wide, and, like the hardened drive-through facilities, can accommodate all known and likely planned launchers, missile support vehicles, and equipment. Unlike UGF entrances at other North Korean missile operating bases, there are no large rocks and soil protective berms to help protect them from attack.
No significant changes have been observed in satellite imagery from 2014 to the present at either of the UGF entrances. However, similar to the base’s two hardened drive-through facilities, the growth of vegetation around the entrances has made it increasingly challenging to locate them using commercial satellite imagery.
The UGF itself was built between 2006 and 2014, and the straight-line distance between the two entrances is approximately 258 meters. However, given what is known concerning large North Korean UGF construction, it is likely that the UGF is considerably longer and contains several side galleries. Although additional small underground facilities or bunkers at the Sinpung-dong base are also likely, none have been reliably confirmed to date.
Back at the two checkpoints at the foot of the main valley, the second checkpoint leads east to branch valley #1. This approximately 2-kilometer-long valley consists of another small headquarters area, barracks, and support buildings. Notably, the valley also features three narrow bunkers on its south side. These appear to be 40 to 55-meter-long Type 500 bunkers that are typically used to house vehicles of various types. 7 Collectively, these elements in the branch valley likely support a battalion-sized armor, mechanized, or motorized unit of unknown type. Because these bunkers and the headquarters area appear in images taken before the construction of the base, the unit housed here may not have originally been intended to be a part of the planned missile base.
Approximately 600 meters up from the checkpoint at the foot of the main valley is the entrance to branch valley #2, which extends approximately 1.5 kilometers to the east. With one exception, this valley is dedicated to a small number of agricultural support and logging activities. However, the one exception is notable. An approximately 24-meter-by-7-meter open earth-bermed support structure is located approximately 650 meters up the branch valley on its north side (40.308947 125.278393). Constructed sometime between 2013 and 2014, this is one of two such structures located within the Sinpung-dong missile operating base.
