North Korea's Kim oversees test of high-thrust engine: state media

Kim Jong Un personally oversaw a ground test of an upgraded rocket engine, North Korean state media reported Sunday, underscoring the regime's continued advancement of its ballistic missile capabilities. The test represents another milestone in Pyongyang's long-running effort to develop missiles capable of reaching distant targets, including the U.S. mainland. Such engine tests are crucial precursors to flight tests and deployment, allowing engineers to validate thrust, durability, and performance before operational use. North Korea has accelerated weapons development in recent years despite international sanctions, conducting multiple missile launches and nuclear tests. The upgraded engine suggests the regime is working to enhance the range, payload capacity, or reliability of its existing arsenal.
