Location: Between Kungmangbong (國望峰) and Mujungbong (霧中峰), Yŏngjŏ-ri (嶺底里), Kimhyŏngjik-kun (金亨稷郡), Yanggang Province (兩江道), North Korea, about 20km from the Chinese border [Note: "Yŏngjŏ-ri" is often misidentified as "Yŏngjŏ-dong (嶺底洞)" but the actual administrative unit is a "ri (里)."]

Subordinate to: Missile Division (미사일 師團), Ministry of the People's Armed Forces (人民武力省), National Defense Commission (國防委員會)

Size: The facility is underground, so the precise scale is unknown. In March 2001, the base was said to have 20 Nodong missiles, but a high-level South Korean military official has denied these reports.

Primary function: Storage, deployment and launch of Nodong and possibly Paektusan/Taepodong missiles

Description: Reports about a missile base under construction at "Yong'ŏ-dong" (용어동) in the central northern region near Mt. Paektu originated with a defector who fled to Japan. However, "Yong'ŏ-dong" is an incorrect name for the location " Yŏngjŏ-ri." According to Kenki Aoyama, Kim Il Sung ordered the evacuation of all citizens from the area in 1993 for the construction of a missile base, and construction began by the mid-1990s in the area between Kungmangbong and Mujungbong near Yŏngjŏ-ri. During the construction period, North Korea used Hwoeyang Station (檜陽驛) to unload construction materials even though it was about 3-5km farther than Wŏlt'an Station (月灘驛). According to Aoyama, the unloading facility and road around Hwoeyang Station were superior to those at Wŏlt'an Station, which are narrow and steep. Aoyama claims there are 12 tunnels at the base; six of them are for missiles, and six of them are for personnel and supplies. Each missile tunnel has five or six compartments for a missile; therefore, the base should have a capacity of about 36 missiles.

In July 1999, a South Korean report noted that 70% of the base construction had been completed and that the base would have 10 launchers for both the Nodong-1 and "Taepodong-1" (Paektusan-1) missiles. Twenty Nodong missiles may have been deployed to the base in early 2000, but construction of the base was still in its final stages in March 2001. The base likely houses Nodong missiles with mobile launchers rather than fixed missile silos or fixed launchers.

In October 2002, North Korea admitted that it possesses a program to enrich uranium, and the Yŏngjŏ-ri is a suspected site for this program. According to "intelligence and diplomatic sources in Seoul," US government officials briefed the South Korean government around 10 October 2002 about North Korea's uranium enrichment program. "Yŏngjŏ-dong" (sic) was one of three suspected sites; the others were "Hagap" and the "Academy of Sciences" in Pyongyang. It is unclear whether US officials have identified a separate facility in Yŏngjŏ-ri dedicated to uranium enrichment, or if the site previously identified as a missile base is a uranium enrichment facility instead.
