Democratic People's Republic of Korea
Nuclear-armed state; proliferation and munitions supply concern
Source: SIPRI / IISS / CRS
North Korea possesses nuclear weapons and is advancing its ICBM capability. It is assessed to have supplied significant quantities of artillery ammunition and ballistic missiles to Russia for use in Ukraine. Its conventional military is large but aging. The principal threat is nuclear miscalculation and continued proliferation.
North Korea's ICBM programme has demonstrated the capability to reach the continental United States. It has supplied Russia with ballistic missiles confirmed used in Ukraine, and open-source investigations in 2025 continued to document large-scale artillery, missile, and personnel support to Russia. FAS assesses North Korea may have enough fissile material for up to 90 warheads but likely has assembled roughly 50. Cyber operations remain a significant revenue generation and espionage tool.
Juche (self-reliance) and Songun (military-first) ideologies provide the political foundation for weapons development. Kim Jong-un has enshrined nuclear weapons in the constitution (2022) as an irreversible policy. The nuclear programme is not a negotiating chip — it is the regime's existential insurance policy.
De facto nuclear recognition and parity with South Korea as sovereign equal Korean state. Extraction of economic concessions from US, South Korea, and Japan in exchange for partial arms control measures. Increasingly, participation in the Russia-China counter-Western bloc as a strategic partner (shifting from pariah to valued supplier).
Est. 40-50 warheads. Hwasong-15/17/18 ICBM range covers continental US. Miniaturisation assessed as achieved.
Extensive missile arsenal. Hwasong family ICBMs. KN-23/24/25 short-range. Supplied to Russia confirmed.
Lazarus Group. Cryptocurrency theft for sanctions evasion. Significant revenue generation via cyber crime.
Large but equipment aging and poorly maintained. Artillery threat to Seoul is existential-level concern.
~6,000 artillery pieces. Many within range of Seoul. Long-range multiple rocket systems.
| System | Type | Range | Payload | Guidance | CEP |
|---|---|---|---|---|---|
| KN-23 (DPRK Iskander) | Short-range ballistic missile | 600–900 km | ~480 kg | Inertial + terminal optical/IR | 5–10 m |
| KN-24 | Short-range ballistic missile | ~400–800 km | ~500 kg | INS + GPS equivalent | ~10 m |
| Hwasong-15 | Intercontinental ballistic missile (ICBM) | 13,000+ km (lofted estimate) | Single large warhead, possibly multi-warhead capable | Inertial | Est. ~1 km |
| Hwasong-18 | Solid-fuelled ICBM | ~15,000 km (estimated) | Single/multi warhead | Advanced inertial | Est. ~1 km or better |
| Pukguksong-3 SLBM | Submarine-launched ballistic missile | ~1,900 km | Single warhead | Inertial | Unknown |
Multiple UAVs crossed South Korean airspace in December 2022, reaching Seoul undetected. Demonstrated gap in ROK low-altitude air defence. Improving capability.
DPRK assessed to be developing Shahed-type loitering munitions based on Iranian technology transfer and Ukraine experience. Not yet confirmed as operational.
1 confirmed; ballistic missile launch capability; range to Japan/Guam from launch points near coast
Represents fundamental shift — sea-based deterrent, harder to destroy in first strike.
~70+ boats; 1950s-60s technology; primarily coastal/littoral; torpedo and mine-laying
Antiquated but numerous. Cheonan sinking (2010) demonstrated combat capability. Used for infiltration operations.
Kh-35 derivative, range ~250 km, sea-skimming terminal phase
Coastal defence and naval use. Transferred to Russian inventory (limited).
GPS jamming capability demonstrated multiple times — disrupted civilian aviation GPS in Seoul in 2016 and 2024 incidents. Limited scope — primarily GPS denial, not broad-spectrum EW.
Cyber capabilities (Lazarus Group, Kimsuky) provide a major offset for limited physical SIGINT. Kimsuky focuses on political intelligence collection targeting South Korean and US government networks.
GPS jamming from ground stations in North Korea (civilian GPS disruption in Seoul documented). Cyber operations partially compensate for limited traditional EW. Russian technology transfers may improve EW capability significantly in coming years.
DPRK supplied est. 5,000–6,000 KN-23 ballistic missiles to Russia (White House/ROK NIS assessment). Deliveries confirmed via forensic analysis of Korean-language KN-23 debris recovered in Ukraine.
Kim Jong-un inspected ballistic missile and munitions production facilities; confirmed and accelerated DPRK-Russia military cooperation. DPRK troops (est. 10,000+) deploying to Kursk Oblast per US/UK intelligence.
UN Panel of Experts report confirmed continued DPRK oil imports and weapons exports in violation of UNSC sanctions; China and Russia vetoed renewal of UN Panel of Experts mandate, effectively ending UN sanctions monitoring.
Reports of additional Hwasong-series ICBM test preparations observed via satellite imagery. DPRK consolidated solid-fuelled ICBM force (Hwasong-18) as primary deterrent platform.
DPRK Lazarus Group conducted cryptocurrency theft totalling ~$1.3Bn in 2024 (Chainalysis estimate), providing hard currency despite sanctions. Bybit exchange hack in Feb 2025 attributed to Lazarus.
DPRK-Russia summit communiqué committed to expanded military technology sharing. Reports of Russian assistance with DPRK satellite programme and submarine technology in exchange for continued munitions supply.
38 North reported two small communities bordering Sohae Satellite Launching Station were demolished in March 2026, while construction and expansion at the launch complex continued.
DPRK will continue weapons exports to Russia and use the Ukraine conflict as a live testing ground for KN-23 accuracy and performance. Crypto-theft operations will continue to fund hard-currency needs. Kim is unlikely to conduct a nuclear test before any potential Trump-Kim summitry.
DPRK is moving toward tactical nuclear weapons miniaturisation. A 7th nuclear test is possible in 2025 to validate miniaturised warhead designs. Russian technology transfers (possibly including submarine nuclear propulsion knowledge) will improve DPRK capabilities significantly. DPRK may seek bilateral security guarantees from Russia formalising its new role as a military partner rather than pariah.
COA 1: Continue munitions supply to Russia for cash, food, energy, and technology — now the primary revenue and capability development channel.
COA 2: Conduct 7th nuclear test to validate tactical nuclear warhead design, then demonstrate via missile test.
COA 3: Pursue bilateral security treaty with Russia, fundamentally changing its strategic position from isolated pariah to Russian-allied nuclear state.
Absolute authoritarian control under Kim Jong-un. Third generation of Kim dynasty, with no evident succession mechanism. WPK/CMC nominally govern; Kim has absolute authority over all decisions. Nuclear weapons embedded in constitution (2022) — irreversible. Russia partnership has elevated DPRK's strategic confidence significantly.
Songun (military-first) policy. ~1.2 million active personnel (world's 4th largest). Disproportionate defence spending (~25% GDP estimated). Nuclear weapons as supreme deterrent and regime survival guarantee. Conventional forces large but technologically obsolete (1960s–70s equipment mostly).
GDP est. ~$18Bn (purchasing power). Essentially subsistence economy for most citizens. Severe sanctions have reduced registered trade by ~90%. Cryptocurrency theft ($1.3Bn in 2024 alone) provides hard currency. Russia munitions contracts now the primary legitimate revenue stream.
Extreme information isolation. Population survival dependent on state. Songbun class stratification. Widespread malnutrition in rural areas. Elite in Pyongyang has growing material prosperity. Defector testimonies describe increasing enforcement of loyalty structures.
Virtually complete domestic information isolation. No foreign media access. Active external cyber operations (Lazarus Group, Kimsuky) for intelligence collection and financial theft. DPRK conducts some international propaganda but primary audience is domestic.
Decrepit civilian infrastructure. Military infrastructure maintained at high priority. Railway is primary logistics network. Limited and unreliable power grid limits industrial development.
Mountainous terrain provides significant defensive depth against invasion. Chinese border (~1,400 km) is the primary economic lifeline. DMZ with South Korea is one of the world's most heavily fortified frontiers.
Time strongly favours DPRK — each year expands the nuclear arsenal and ICBM force. US disarmament goal becomes less viable each year. Russia-Ukraine war has opened new revenue streams that remove previous pressure on DPRK to seek economic accommodation.
Nuclear arsenal and ICBM capability — provides the ultimate regime survival guarantee by threatening the US homeland, making regime change via military force an unacceptable risk for Washington.
Kim Jong-un commands all military and political institutions directly through WPK/CMC with no intermediary authority. DPRK troops in Russia are operationally subordinate to Russian command (per US intelligence) while strategic direction remains with Kim.
DPRK doctrine deters US-ROK military action through nuclear and missile capability while threatening Seoul with massive conventional artillery to deter regime change. The 2022 nuclear doctrine revision explicitly authorised pre-emptive nuclear use if regime existence is assessed as threatened — a departure from all other nuclear powers' stated doctrines. This creates a highly unstable deterrence dynamic.
Dense layered SAM systems (SA-2/3/5/6 mix) provide area denial against non-stealthy aircraft. Underground facility network hardens key assets against pre-emptive strike. Road-mobile ICBMs disperse to deny fixed targeting. Forward artillery as primary strategic deterrent against ROK population centres.
DPRK ICBMs directly threaten US CONUS, straining extended deterrence credibility. NK ammunition and troop supply to Russia is a direct material contribution to the conflict against NATO-armed Ukraine. Technology proliferation risk — DPRK sells missile technology to Iran and potentially others. Kim-Putin 2023 agreement marks DPRK's formal entry into a coordinated anti-Western coalition.
Declared first-use policy. Nuclear use authorised if regime existence threatened. Stated preemptive strike doctrine.
Solid-fuel ICBM. Reduces launch preparation time significantly vs liquid-fuel predecessors.
Artillery ammunition and KN-23 ballistic missiles confirmed supplied. Assessed millions of rounds transferred.
Hero Kim Kun Ok submarine test-launched missiles 2023. Capability limited but developing.
The White House confirmed in October 2024 that North Korea had deployed up to 10,000 troops for service with Russian forces in Kursk Oblast — the first DPRK military operation outside the peninsula since the Korean War. KPA soldiers were confirmed in combat by January 2025 with significant casualties reported. Russia reportedly provided technology transfers, hard currency, and food aid in exchange.
North Korea successfully launched Malligyong-1, its first operational military reconnaissance satellite, on November 21, 2023. US analysts assessed that Russian assistance provided after the September 2023 Putin–Kim summit enabled the previously failed programme. The satellite provides periodic surveillance capability over South Korea, Japan, and US Pacific installations. A second satellite was launched in 2024.
North Korea supplied Russia with KN-23 quasi-ballistic missiles and KN-25 600mm rockets from late 2023. US and South Korean intelligence confirmed deliveries; debris with Korean-language markings was recovered in Ukraine. An estimated 3–5 million 122mm and 152mm artillery shells were also transferred. These substantially augmented Russian fire rate capacity. This represents the largest arms export in DPRK history.
Kim Jong Un's September 2023 visit to Russia included inspections of Vostochny Cosmodrome, the Su-57 fighter, and Tu-160 bomber. Russia reportedly agreed to provide satellite technology — explaining DPRK's successful Malligyong-1 launch in November 2023 — alongside advanced ballistic missile re-entry vehicle and potential submarine technology. The transfers form the strategic quid pro quo for DPRK arms deliveries to Russia.
DPRK's solid-fuelled ICBM capability (Hwasong-18) directly threatens the US homeland for the first time since the Cold War, straining extended deterrence credibility. Its proven ability to supply 5,000+ ballistic missiles to Russia has materially extended the Ukraine war. A nuclear test validating tactical warhead designs would lower the threshold for nuclear use in any Korean Peninsula contingency.
