As North Korea deepens ties with Russia, growing speculation suggests the two regimes may be Russia secretly helping North Korea to build underground weapons factories hidden from Western surveillance. What’s really happening beneath the surface?
In the shadow of tightening Western sanctions and intensifying global scrutiny, a dangerous new axis appears to be taking shape not just in open declarations of political support or military partnerships, but deep underground.
As Russia and North Korea draw closer amid the war in Ukraine and broader East-West tensions, new intelligence signals and satellite imagery hint at the existence of what insiders are now calling “Ghost Factories” – secretive underground military tech facilities allegedly being constructed inside North Korea, potentially with Russian assistance.
Russia and North Korea: An Alliance Built in the Dark
Russian Foreign Minister Sergey Lavrov recently described relations with Pyongyang as an “invincible fighting brotherhood.” Behind this overt camaraderie lies a more discreet and dangerous development: military-industrial collaboration designed to evade U.S. satellites, sanctions, and international oversight.
What’s the Motivation?
- For North Korea: Underground facilities mean more security for its ballistic missile programs, nuclear warhead assembly, and missile component production, especially after past aerial surveillance by the U.S. revealed crucial launch sites.
- For Russia: With much of its own defense production strained by sanctions and Ukraine’s counteroffensives, Moscow could offload blacksite manufacturing to its isolated ally tapping into cheap labor and shared hostility toward the West.
The Rise of North Korea’s Underground Military Infrastructure
North Korea already has a long history of building underground facilities (UGFs) dating back to the Korean War. These bunkers house artillery, fighter jets, and even missile silos. But recent satellite data from open-source analysts at Beyond Parallel and 38 North suggest new excavation activity near Mt. Chonma, the Panghyon Airbase, and Kusong, sites historically linked to DPRK’s missile testing and nuclear programs.
According to a 2024 report by South Korea’s Defense Ministry, seismic disturbances were detected in non-earthquake zones, suggesting deep drilling or tunneling projects not consistent with natural activity.
Evidence of Russian Involvement: Smoke Without Fire?
While there is no official confirmation of Russia’s hand in building these new “ghost factories,” a combination of circumstantial clues, strategic benefits, and covert alliances creates a compelling case:
1. Technical Expertise Transfers
Several defectors and leaked intelligence memos from Western sources have alleged that Russian engineers particularly those with past military or nuclear experience have traveled to North Korea through unmonitored routes via Vladivostok or ferry-based trade channels.
These experts could be helping DPRK modernize tunneling methods, ventilation systems, and radiation-shielded labs for nuclear weapon assembly or hypersonic missile research.
2. Joint Military Construction Units
In July 2025, it was confirmed that North Korea is sending over 6,000 military engineers to Russia’s Kursk region. Analysts believe this labor exchange could be reciprocal with Russian military engineers or retired technicians traveling back to the DPRK to assist in underground infrastructure projects. North Korea Ghost Factories issue arise.
3. Satellite Silence
Advanced satellite monitoring systems, such as those operated by Maxar Technologies, show distinct patterns of concealment camouflaged construction, thermal suppression to mask heat signatures, and tunnel blasting away from main roads. These are tactics Russia has used in its Siberian weapons depots and Arctic bases.
Why Build Underground?
The strategic rationale for building underground military factories is clear:
- Survivability: Above-ground weapons factories are vulnerable to pre-emptive strikes, especially from U.S. stealth bombers and cruise missiles. Underground facilities offer better protection and secrecy.
- Detection Evasion: Hidden factories reduce the risk of exposure by satellites and international watchdogs like the IAEA or UN Panel of Experts.
- Continuous Production: Even in wartime, underground networks allow for uninterrupted missile production, warhead assembly, and component testing.
Strategic Implications for the West and the Indo-Pacific
The emergence of Russian-backed ghost factories in North Korea would mark a game-changing moment for regional stability. Here’s how:
- Missile Proliferation: It would allow Pyongyang to mass-produce ballistic missiles without fear of Western intervention possibly supplying them to Russia, Iran, or non-state actors.
- Nuclear Ambiguity: Underground facilities make it harder to verify North Korea’s nuclear arsenal, reducing the effectiveness of deterrence and diplomacy.
- Intelligence Blind Spots: U.S. and allied satellite programs rely on visible activity for threat assessment. Underground bunkers render traditional surveillance methods less useful, forcing a heavier dependence on cyber espionage and HUMINT (human intelligence).

What’s Next: Proving the Unprovable?
The very nature of a ghost factory is that it leaves no public footprint. However, international watchdogs are beginning to take note. The UN Security Council’s sanctions committee on North Korea is reportedly reviewing new satellite data, while South Korea’s National Intelligence Service (NIS) has upgraded its alerts for underground activity linked to Russian collaboration.
A Dark Future Beneath the Surface?
As Russia becomes more isolated and North Korea continues its nuclear ambitions, the rise of secretive underground military tech hubs could become a new norm in authoritarian warfare strategy.
These ghost factories hidden beneath rock, shielded by politics, and powered by desperation may one day become the epicenter of the world’s next major military crisis.
Whether or not proof of direct Russian involvement surfaces in the coming months, one thing is certain: the West can no longer afford to only look above ground.
