SEOUL, March 20 (Reuters) - 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.
"And without launch preparations being detected in advance, you can just press a button."
Unlike the KN-23, liquid-fuelled missiles such as North Korea's Hwasong-17 ICBM require time for fuelling.
With a silo that can take place underground, out of sight.
North Korea typically relies on mobile launchers, but the country's lack of infrastructure could make launches from such trucks challenging, Yang said.
