The missile flew about 1,000 kilometers (620 miles) and landed in the sea east of Japan, but it crested at a remarkable 4,500 kilometers (2,800 miles) above the Earth’s surface, making it the highest and longest-lasting flight North Korea has completed to date.
North Korea had previously tested ICBMs, but those did not display ranges sufficient to hit important targets on the US’s East Coast.
David Wright, a physicist and the codirector of the Union of Concerned Scientists’ global security program, wrote recently that North Korea’s latest missile could likely fly 8,100 miles on a normal trajectory, enough to reach anywhere in the continental US.
But while the test demonstrated range, it’s still unknown how credible the launch was. An effective ICBM has to carry a payload of about 1,000 pounds, and it’s unclear if this launch had a reduced load.
