Kim Jong Un, the leader, recently watched a crucial test of a new missile engine. State media reported that he called this a huge step forward for the nation’s nuclear defenses. This advanced engine uses a special carbon fiber material and runs on solid fuel. Experts believe it will power the country’s next-generation long-range missiles.
According to the state news agency KCNA, the test happened under Kim Jong Un’s direct guidance. This event, reported on September 9, 2025, marked what he called a “strategic success.” It signifies a major shift in how the country plans to strengthen its nuclear military power. Such developments always draw attention on the global stage, given the implications for international security.
The Missile Administration and the Chemical Materials Research Center worked together on this project. This was the ninth and final test run for the new engine, meaning its development phase is now complete. Officials claim the engine can produce an impressive 1,971 kilonewtons of thrust. A solid-fuel engine is a big deal because it allows missiles to be launched much more quickly and secretly compared to liquid-fueled versions.
This advanced engine is expected to be the heart of the new “Hwasong-20” intercontinental ballistic missile. Just last week, Kim Jong Un visited the research institute that created the engine. During that visit, he announced the Hwasong-20, confirming its connection to this new technology. This suggests the country is moving fast with its missile program.
Last year, specifically on October 31, the country tested its Hwasong-19 solid-fuel missile. That was then called the “final upgraded version.” However, the creation of this new, more powerful engine means that the Hwasong-20 program is set to progress even faster. It truly represents a significant leap, pushing the boundaries of missile technology for the nation.
