North Korea Tests Advanced Rocket Engine Capable of Striking U.S. Mainland
On Sunday, March 29, 2026, the state-run news agency KCNA reported that leader Kim Jong Un personally supervised the test of the enhanced engine variant. Defense experts believe this high-thrust engine is designed for long-range Intercontinental Ballistic Missiles (ICBMs) capable of reaching the United States mainland, marking a significant escalation in Pyongyang's strategic strike capabilities.
The primary advancement in this latest test lies in the engine’s propulsion power. The "thrust" capacity has increased to 2,500 kilonewtons, up from the 1,971 kilonewtons recorded during a similar test in September of last year. This increase in power suggests that North Korea is developing larger missiles capable of carrying heavier payloads, including multiple warheads (MIRVs) designed to overwhelm and bypass modern U.S. missile defense systems.
The shift toward solid-fuel technology represents a critical tactical advantage for North Korea. Unlike liquid-fueled missiles, which require a lengthy and visible fueling process before launch, solid-fuel missiles can be stored pre-loaded and launched with minimal preparation time. This rapid-deployment capability makes them significantly harder for enemy radar and satellite surveillance to detect and intercept. Analysts suggest this test is a clear signal that North Korea is accelerating its goal of building a more resilient and unpredictable nuclear deterrent.
