SEOUL, South Korea – North Korean leader Kim Jong Un has personally supervised a critical test of an advanced solid-fuel engine designed for strategic weapons systems, state media confirmed Sunday. The Korean Central News Agency (KCNA) reported this development represents a significant enhancement to the nation’s military capabilities.
The newly upgraded engine utilizes composite carbon fiber materials and demonstrates a maximum thrust of 2,500 kilotons, marking a substantial improvement over the 1,971 kilotons recorded during previous testing in September. This technological advancement occurs within the framework of North Korea’s five-year military modernization program, which explicitly prioritizes the enhancement of strategic strike capabilities.
Military analysts suggest this engine development correlates with Pyongyang’s efforts to develop multiple independently targetable reentry vehicle (MIRV) technology, which would enable a single missile to deliver multiple warheads and potentially overwhelm United States missile defense systems.
The test follows Kim Jong Un’s recent address to North Korea’s Parliament where he unequivocally affirmed the country’s status as a nuclear power and accused the United States of engaging in what he termed ‘state terrorism and aggression’ in reference to ongoing conflicts in the Middle East.
Solid-fuel missiles represent a significant strategic advancement as they require minimal preparation time compared to liquid-fuel counterparts and can be launched with greater stealth, making detection prior to launch considerably more challenging for defense systems.
While some weapons experts maintain that North Korea still faces technical hurdles in developing fully functional intercontinental ballistic missiles capable of surviving atmospheric re-entry, others argue the country’s sustained investment in nuclear and missile programs suggests substantial progress.
North Korea’s weapons development has accelerated markedly since the collapse of diplomatic talks with the United States in 2019. During the ruling Workers’ Party congress in February, Kim indicated openness to dialogue while simultaneously demanding the United States abandon its stance on North Korean denuclearization as a precondition for negotiations.
