North Korea Tests Solid-Fuel Missile Engine Targeting U.S. Mainland

• •North Korea tested a solid-fuel missile engine with a thrust of 2,500 kilonewtons.
• •The test is part of a five-year military enhancement strategy by North Korea.
• •Experts question the validity of North Korea's claims due to lack of detailed information.

On March 29, 2026, North Korea conducted a test of an upgraded solid-fuel engine for missiles capable of reaching the U.S. mainland, according to state media. Kim Jong Un observed the test, which is part of a five-year arms build-up aimed at enhancing the country's strategic military capabilities. The engine reportedly has a maximum thrust of 2,500 kilonewtons, an increase from 1,970 kilonewtons in a previous test. Experts suggest that North Korea's claims may be exaggerated due to a lack of detailed information about the test, such as the total combustion time. The test aligns with Kim's objective of developing more agile and hard-to-detect missiles. While the specific date and location of the test remain undisclosed, it is part of North Korea's ongoing efforts to bolster its military arsenal. The implications of this development raise concerns among U.S. and allied defense analysts regarding regional security.
