North Korea conducts test of new high-thrust solid-fuel rocket engine

North Korean leader Kim Jong Un personally supervised the ground-based test of a new high-thrust solid-fuel rocket engine. State news agency KCNA reported the engine utilizes carbon fiber composite materials to improve performance, with thrust output reaching 2,500 kilonewtons compared to 1,971 kilonewtons in a previous test from September 2025. This development is part of a five-year military plan to upgrade the nation's strategic strike capabilities. Analysts suggest the increased power aims to support intercontinental ballistic missiles (ICBMs) capable of carrying multiple warheads and reaching the United States. Solid-fuel technology allows for faster launch preparations and harder detection, enhancing the country's nuclear deterrent. Kim recently reiterated his commitment to solidifying the country as a nuclear power during a parliamentary address. Unconfirmed reports also allege potential involvement of Russian technical teams in the program. Experts anticipate the successful testing of this engine paves the way for a future flight test of a long-range ballistic missile.
