Fact Sheet: North Korea's Nuclear and Ballistic Missile Programs

By Duyeon Kim

July 2013

KEY TAKEAWAYS

• North Korea currently possesses between four and eight nuclear weapons. It has carried out three nuclear tests since 2006.

• It has developed and tested a range of short- and medium-range missiles, but has yet to successfully test a long-range missile or ICBM.

• It is generally believed to have not yet developed the capabilities needed to miniaturize a nuclear device for missile delivery.

NUCLEAR WEAPONS CAPABILITIES

Claimed Objective: Deter a U.S. invasion and hostile policy against it, such as U.S. sanctions and joint military exercises with South Korea. Pyongyang believes the United States desires regime change.

Apparent Objective: Regime survival and recognition as a nuclear power. The regime believes that its nuclear and ballistic missile programs enhance its security and diplomatic position (1) domestically, as a demonstration of strength against hostile Americans, and (2) internationally, as a bargaining chip and means to be treated as equal to nuclear weapons states. The regime has recently revised its constitution, which now refers to North Korea as a nuclear weapon state, a status that, in the international arena, is only granted to the five states that possessed nuclear weapons in 1968, when the Nuclear Non-Proliferation Treaty was opened for signatures (the United States, the Soviet Union (now Russia), the United Kingdom, France, and China). Pyongyang also appears to be pursuing the ability to miniaturize a nuclear warhead and mount it on a long-range ballistic missile.

Number of nuclear weapons: Unverified, but total plutonium production suggests between four to eight nuclear weapons.

Nuclear Programs

Plutonium

Facilities: Yongbyon nuclear complex; North Hamgyong Province (Chungjinsi, Kiljugun, Pungyre); Chagangdo Province (Kanggyesi); North Pyongan Provice (Yongbyonsi, Kusungsi, Taechongun); South Pyongan Provice (Pyongsungsi)

Stockpile: Believed to be between 30 kg and 50 kg, with a portion of the stockpile having actually been used in North Korea’s nuclear tests.

Uranium Enrichment

  • Facilities
    Suspected – Pyongyang; Pakchon; Taechon; Chonmasan; Hagap; Yongjori;
    Confirmed – Yongbyon (pilot plant). In November 2010, Pyongyang unveiled a pilot uranium enrichment plant to American scientist Siegfried Hecker. It is widely believed to be a cover for its clandestine uranium enrichment programs, and not intended for peaceful nuclear energy generation. Other sites are believed to be hidden.
  • Stockpile: Unknown. It is virtually impossible to verify enriched uranium stockpiles from a technical standpoint.

Nuclear Testing

Apparent Objective: To miniaturize a nuclear warhead to mount on a long-range missile.

Nuclear tests: Three.

1. October 2006 – Claimed successful. Deemed unsuccessful.

On October 16, the U.S. Director of National Intelligence confirmed “North Korea conducted an underground nuclear explosion in the vicinity of P'unggye on October 9, 2006. The explosion yield was less than a kiloton,” and later said it was apparently more successful. One kiloton is far less than other nuclear states’ first tests of 10-20 kt. The international community has called the North’s test a failure.

2. May 25, 2009 – Claimed successful. Deemed unsuccessful.

On June 15, the U.S. Director of National Intelligence stated, “The U.S. Intelligence Community assesses that North Korea probably conducted an underground nuclear explosion in the vicinity of P’unggye on May 25, 2009. The explosion yield was approximately a few kilotons. Analysis of the event continues.” However, there is a lack of conclusive physical evidence in open sources that proves the test was a nuclear one. Official and unofficial reports vary on estimated yield but it is generally regarded as higher than its 2006 test.

Test site: Pungyre (Northeast, 2006 & 2009 test site); Yongdoktong (Northwest; speculated)

Nuclear site: Kumchangri (underground site speculated to house a nuclear facility)

3. February 12, 2013 - Claimed successful. Widely deemed successful.

On February 12, the U.S. Director of National Intelligence stated, “The U.S. Intelligence Community assesses that North Korea probably conducted an underground nuclear explosion in the vicinity of P’unggye on February 12, 2013. The explosion yield was approximately several kilotons. Analysis of the event continues.” The estimated yield remains unclear, In addition, some experts speculated that the test involved uranium, rather than plutonium as in the case of the last two tests, but there has been no official confirmation regarding which material was involved in the test.

It is unclear how soon Pyongyang will be able to miniaturize a nuclear warhead to mount on a missile. In April 2013, the US Defense Intelligence Agency asserted that it had “moderate confidence” that North Korea had developed this ability. However, this claim has not been corroborated by other US or South Korean intelligence agencies. In a May 2013 analysis, the Arms Control Association’s Greg Thielmann, a Senior Fellow at the Arms Control Association, wrote that, “Although [North Korea] has hundreds of operational short- and medium-range ballistic missiles, there is no evidence that it has achieved the miniaturization of a nuclear device necessary for arming these missiles.”

BALLISTIC MISSILE CAPABILITIES

Apparent Objective: Improve conventional war capabilities. Develop missiles capable of delivering nuclear warheads targeted at regional adversaries and the continental US. A grave concern remains the possible development of an inter-continental ballistic missile capable of delivering a chemical, biological, or nuclear warhead that can reach the U.S. continent. Given repeated test failures, most missile experts believe Pyongyang is far from achieving this goal.

Ballistic Missile Facility: Musudan-ri; Yongjo-ri; Sangnam-ri; Tongchang-ri, Chiha-ri

Delivery Systems (Ballistic Missiles)

Short-Range

KN-01 – short-range anti-ship cruise missile. Range estimated at 160 km. Believed to be an improved version of the Soviet Termit missile (“Styx”).

KN-02 – short-range, solid-fueled, highly accurate mobile missile. Range estimated between 100-120 km. Modified copy of the Soviet OTR-21 (SS-21 Tochka; also referred to as “Scarab”); unknown number in service; believed to have been deployed in the late 1990s or early 2000s.

Hwasong-5 (Scud-B) – short-range, initial Scud modification. Road-mobile, liquid-fueled missile. Estimated range of 300 km (can reach throughout South Korea) and capable of delivering a 900 kg payload. Tested successfully. First deployed in 1988. Delivered to Iran for Iraq-Iran war.

Hwasong-6 (Scud-C, Scud-PIP) - Improved version of Hwasong-5. Range of 500 km, able to carry 700-800 kg payload. First deployed in 1988. Said to be the most widely deployed missile, with at least 400 in service.

Medium-Range

Rodong (Nodong-1)– medium-range missile with an estimated range of 1,000-1,500 km; payload of 1,000 kg. Capable of reaching across Japan; capable of carrying a simple nuclear warhead, according to analysis from ISIS. First deployed in 1998. DPRK has deployed between 175 and 200 of these missiles. Certain sources have mentioned the existence of a Rodong-2, but studies from RAND and the James Martin Center for Nonproliferation Studies assert that it does not exist, or may be another name for the Taepodong-1.

Intermediate-Range

Taepodong-1 (Paektusan-1) – two-stage liquid-fueled medium-range ballistic missile, modified to serve as a three-stage space launch vehicle; incapable of delivering nuclear payload to intercontinental ranges due to poor technical accuracy; estimated range of 2,000-2,900 km. Theoretically capable of delivering small 100-200 kg payloads to continental US, but that payload is far too small for a nuclear weapon, and so the Taepodong-1 cannot be considered a usable ICBM. Was tested with partial success in 1998, with the missile experiencing a third-stage failure.

Taepodong-2 (Paektusan-2/Unha-2/Unha-3) – larger, more capable multi-stage missile; currently under development. Depending on size of payload, possible strategic capability against continental U.S; believed to be a potential intercontinental ballistic missile; exact range unknown, various government estimates of possible ranges run from 3,400-15,000 km. Was tested five times between 2006 and 2013, with its only successful flight coming in December 2012, when it was used as a space-launch vehicle. According to a 2012 report from the Department of Defense, the Taepodong-2 has yet to be deployed by the North Korean military.

Musudan-1 (Taepodong-X, Nodong-B, BM-25) – single-stage intermediate range ballistic missile (IRBM); range 2,500-4,000 km capable of direct strikes on South Korea, Japan, and Guam, thus putting U.S. military bases at risk; Has not been tested and is not known to be operational.

Intercontinental Ballistic Missiles (ICBM)

KN08 -- North Korean road mobile ICBM; first presented at parade in April 2012, but many analysts argue that the missiles on display were only mock-ups. Has not been tested, and no open-source evidence exists to suggest that they are operational.

Long-Range Rockets (Space Launch Vehicles)

Unha rocket-Kwangmyongsong satellite combo -- The North claims its long-range rockets are designed for peaceful scientific purposes to launch a satellite into orbit. However, the UN Security Council and international community view long-range rockets as synonymous with long-range missiles – the technology used in space launchers is essentially the same as ballistic missile technology. Global diplomats and scientists view Pyongyang’s claimed objective as veiled practice rounds to eventually launch a missile tipped with a nuclear warhead.

• June 1990 – Hwasong-6 (Scud-C); successful; launched from Nodong test site over the Sea of Japan.

• July 1991 – mobile Hwasong-6 (Scud-C); successful; launched from military base in Kangwon Province towards target in Sea of Japan.

• Fall 1991 – Joint Chinese-North Korean MRBM prototype; tested at Yinchuan, China.

• June 1992 – Rodong-1; unsuccessful

• May 1993 – Rodong-1; successful; launched from North Hamgyong Province 500 km into the Sea of Japan.

• August 1998 – Taepodong-1; successful; fired from eastern North Korea over Japan; third-stage failed; claimed Kwangmyongsong-1 satellite launch.

• February 2003 – Likely KN-01; unsuccessful; travels only 60 km (range of 160 km); launched from North or South Hamgyong Province into the Sea of Japan.

• March 2003 – Likely KN-01; unsuccessful; explodes in mid-air before reaching target in Sea of Japan.

• May 2005 – Likely KN-02; launched into Sea of Japan.

• July 2006 – Combination of Taepodong-2, Rodong-1, and Scud missiles; Taepodong-2 failed; crashed into Sea of Japan less than one minute after launching.

• April 2009 – Taepodong-2; claimed Kwangmyongsong-2 Rocket and Unha-2 satellite; unsuccessful; crashes in Pacific Ocean.

• July 2009 – Rodong missiles; launched into Sea of Japan.

• April 2012 – Kwangmyongsong-3 satellite and Unha-3 rocket; unsuccessful; launch from northwest North Korea; possible second stage failure.

• December 2012 – Kwangyongsong-3 and Unha-3 rocket launch; successful; satellite placed into orbit; launch from northwest North Korea.

North Korea has typically tested long-range missiles/rocket before a nuclear test. Over the past two decades, Pyongyang has sold at least a few hundred Hwasong-5/-6 or Rodong missiles, materials, equipment, production technology, and parts to Middle Eastern countries including Egypt, Iran, Libya, Pakistan, Syria, the United Arab Emirates, and Yemen.

NUCLEAR WARHEAD MINIATURIZATION

• After Pyongyang’s nuclear test in February 2013, the Korean Central News Agency, the North Korean government’s official news agency, issued a statement saying that Pyongyang had tested a “miniaturized and lighter device with greater explosive force than previously,” sparking concerns that North Korea had mastered the technology needed to create warheads small enough to be mounted on ballistic missiles.

• In February 2013, David Albright, President of the Institute for Science and International Security, wrote that, “North Korea likely has the capability to mount a plutonium-based nuclear warhead on the shorter range Nodong missile,” while also asserting that Pyongyang has not yet developed this capability with regards to ICBMs.

• In an April 2013 report, the Defense Intelligence Agency expressed “moderate confidence” that North Korea had developed the ability to place a miniaturized nuclear weapon atop a ballistic missile. However, that assertion has not been corroborated by other intelligence agencies, and has been actively disputed by the South Korean government and President Obama, Moreover, it is important to note that the DIA report also stressed that “reliability will be low” for any hypothetical North Korean nuclear missile.
