North Korea Never Halted Missile Efforts

“Just before North Korea launched its first intercontinental ballistic missile in 2017, scientists strapped their newest rocket engine to a test stand to see how it would perform. The liquid-fueled engine burned successfully for 200 seconds and generated enough thrust to propel a warhead halfway around the world,” the Washington Post reports.

“Two years later, on Dec. 13, a new missile engine was lit up on the same test stand while scientists watched. This time the burn lasted 400 seconds — almost seven minutes — according to an official statement.”

“For analysts who closely track such tests, the results were both startling and mystifying. North Korea’s last ICBM was powerful enough to reach the U.S. East Coast. Was this a new booster for the same ICBM? Or something different? No one knew, but experts fear that the world could soon find out.”
