North Korean Nuclear and Missile Programs and Capabilities National Security Agency 6 June 2001 Steve Fetter University of Maryland
Origins DPRK nuclear and missile programs began in mid-60s, given higher priority late 70s Initially, substantial assistance from Russia and China Strategic weapons: prevent involvement of US and Japan in a second Korean War US nuclear threat, ROK missile (and nuclear?) programs also factors
History of Nuclear Program 1950-60s 1964 1965 1975-77 1977 1980 1985 1986 Scientists, engineers train in USSR, China Research center established at Yongbyon USSR delivers 2-MW IRT research reactor DPRK separates Pu from IRT fuel IAEA safeguards begin at IRT reactor Construction begins on 20-MW t reactor USSR pressures DPRK to sign NPT 20-MW reactor starts up Construction begins on 200-MW t reactor, reprocessing plant
History of Nuclear Program 1989 1990-92 1991 1992 1993 20-MW t reactor shut down for 70 days Plutonium separated from spent fuel Bush removes tactical nuclear weapons, suspends Team Spirit; JDDKP signed Safeguards agreement signed, six IAEA inspections; discrepancies discovered IAEA requests special inspections DPRK announces withdrawal from NPT US begins negotiations, DPRK suspends withdrawal from NPT
History of Nuclear Program 1994 20-MW t reactor shut down and fuel unloaded; IAEA unable to tag selected fuel rods; US moves to impose UN sanctions Carter goes to Pyongyang, secures freeze from Kim Il Sung Agreed Framework: freeze and ultimate dismantling of facilities, spent fuel packaged for removal, full compliance with IAEA safeguards, in exchange for fuel oil, easing of sanctions, normalization, two PWRs
North Korean Nuclear Facilities Yongbyon: 3 reactors (IRT, 20 MW t, 200 MW t ), fuel fabrication, plutonium separation Taechon: 800 MW t reactor

Possibilities Past Limited reprocessing, small amount of separated Pu Reactor refueled, enough separated Pu for bomb Deliverable bomb completed Future Existing facilities dismantled; spent fuel removed; past resolved Facilities remain frozen; spent fuel stored; threat of restart and completion Spent fuel reprocessed, reactor restarted, other reactors completed
DPRK Missile Program Most advanced of emerging missile states Largely indigenous, but significant assistance from Russia, China, and other emerging states Existing threat to South Korea and Japan; possible future threat to United States Chemical warheads, possible biological and nuclear warheads Willingness to exports missiles, production facilities to any buyer: Iran, Pakistan, Syria, Libya, Egypt, UAE, Vietnam, Sudan
History: Short-range Scud B 1965-67 1971-78 1979 1984 1986-89 1987-88 Soviets supply FROG missiles Agreement with China, DF61 cancelled Egypt transfers Scud B, DPRK reverseengineers (Hwasong 5) with Chinese help First flight test at Musudan-ri Full-scale production (5-10/mo) Iran buys 100 Scuds, production facilities for $500 million; uses 77 against Iraq
History: Extended-range Scud C 1987-89 1990 1991 1990s Extended-range Scud C (Hwasong 6) developed (lighter frame, payload) to reach all targets in ROK Test at Musudan-ri Full-scale production begins (4-5/mo) Indigenous TEL production, hardened underground bunkers throughout country; sales to UAE, Iran, Syria, possibly Egypt, Vietnam, offered to Sudan
History: Medium-range No-dong 1988-90 1990-92 1993 1993-99 1994-96 1998 Scaled-up version of Scud (No-dong) developed to target Japan (with nuclear warhead?) Test failures/cancellations Only test at Musudan-ri, 500-700 km Full-scale production (2-4/mo) Iran and Pakistan buy No-dong missiles and production facilities Iran tests Shehab, Pakistan tests Ghauri Reports of interest by Egypt, Syria, Libya
History: Long-range Taepo-dong 1990s 1994 1998 1999 Taepo-dong 1 developed to master staging: No-dong first stage, Scud C second stage Taepo-dong 2 developed to deliver large payload to US bases, territory Reports of Russian, Chinese assistance Mock-ups spotted, launch facility expanded Test of 3-stage SLV at Musudan-ri IC judges Taepo-dong 2 launch possible anytime
History: Turn to Diplomacy 1999 2000 2001 Perry review; negotiations begin, DPRK suspends missile tests while talks continue Albright trip: end development, testing, and production of long-range missiles, exports of missile technology in exchange for assistance, satellite launch Existing missiles? Facilities? Verification? Bush policy review

Evolving IC Estimates: NIE 93 At a minimum, North Korea would require nearly 10 years to develop an ICBM capable of delivering a chemical or biological weapon warhead and 10 to 15 years to develop an ICBM to carry a nuclear warhead. However, the probability of North Korean ICBM development is currently low because of competing demands for dwindling resources among existing high priority military programs.
Evolving IC Estimates: NIE 95 In the next 15 years no country other than the major declared nuclear powers will develop a ballistic missile that could threaten the contiguous 48 states or Canada. North Korea is developing a missile that could reach Alaska and the far western portion of the Hawaiian Island chain. North Korea is unlikely, in the next 15 years, to obtain the capability to develop and deploy a longer range ICBM capable of reaching the contiguous 48 states. North Korea would have to develop a new propulsion system, improved guidance and control systems, and conduct a flight test program. Meeting these challenges will take time, given the infrastructure of North Korea, and the political and economic situation in the country.we have no evidence that Pyongyang has begun or intends to begin such a program.
Gates, GAO Reviews of NIE 95 Gates: The Panel found no evidence of politization; the IC s conclusions with respect to the ICBM threat to the US are based on a stronger evidentiary and technical case than was presented in the Estimate. GAO: The level of certainty was overstated but judgments are consistent with available evidence
Rumsfeld Comission (1998) North Korea is working hard on the TD-2. Its status cannot be determined precisely. Once the system is assessed to be ready, a test flight could be conducted within six months. If North Korea judged the test to be a success, the TD-2 could be deployed rapidly. It is unlikely the US would know of such a decision much before the missile was launched. TD-2 could reach major cities and military bases in Alaska and the westernmost islands in Hawaii. Light-weight variations could fly as far as 10,000 km, placing at risk western US territory from Arizona to Wisconsin. These variants would require additional time to develop and test.
Evolving IC Estimates: NIE 99 We project that during the next 15 years the US most likely will face ICBM threats from Russia, China, and North Korea North Korea would view their ICBMs more as strategic weapons of deterrence and coercive diplomacy than as weapons of war. North Korea could convert its TD-1 SLV into an ICBM that could deliver a light payload (sufficient for a biological or chemical weapon) to the US, albeit with inaccuracies that would make hitting large urban targets improbable. North Korea is more likely to weaponize the larger TD-2 as an ICBM that could deliver a several-hundred kilogram payload (sufficient for early generation nuclear weapons) to the US. Most analysts believe it could be tested at any time, probably initially as an SLV, unless it is delayed for political reasons.
Future Possibilities US-DPRK negotiations continue, culminating in agreement to end missile production, testing, exports in exchange for aid; probably no on-site verification US-DPRK negotiations break down; TD-2 is tested and deployed; agreed framework goes down with it
