North Korea Conducts Rocket Engine Test

On June 22, North Korea tested a rocket engine that U.S. officials believe could be part of its program to develop an intercontinental ballistic missile (ICBM). According to one official, the test could be for the smallest stage of an ICBM rocket engine. It is the DPRK’s first rocket engine test since March. The test was reportedly conducted in the city of Yun Song, where previous engine tests have taken place.

Little is known yet about this most recent test. North Korea’s state media has not yet released reports and South Korean officials likewise have not released details about the reported test and declined to comment on the nature of the engine.
