North Korea turns to 'old workhorse' rocket to repeat past success

SEOUL/WASHINGTON (Reuters) - North Korea's weekend rocket launch repeated earlier success rather than breaking new ground, using a nearly identical design from a 2012 launch, experts said, adding the reclusive country probably remained years from building a long-range nuclear missile.

The rocket was based on engines taken from its massive stockpile of mid-range missiles based on Soviet-era technology and electrical parts too rudimentary to be targeted by a global missile control regime, the experts said.
