North Korea has announced a successful test of a new solid-fuel missile engine, describing it as a major step in strengthening its military power.

Leader Kim Jong Un reportedly observed the test, which the state news agency said produced higher thrust than previous versions.

The engine is part of North Korea’s long-term military development plan aimed at improving its missile capabilities.

Solid-fuel technology allows missiles to be launched faster and transported more easily compared to liquid-fuel systems.

However, some experts have raised doubts about the test, noting that important performance details were not revealed.

Analysts say further tests may be needed to confirm the true strength and reliability of the missile program.
