North Korea's presumed use of a silo in its latest missile test was aimed at boosting the speed and reliability of launches, and could be used in future flights of intercontinental ballistic missiles (ICBMs), analysts said on Monday.
State media called Sunday's launch of the solid-fuelled KN-23, a short-range ballistic missile (SRBM), the latest in the isolated country's recent series of missile tests, an element of drills simulating a nuclear counterattack against the U.S. and South Korea.
