The missile was a Hwaseong-17, according to KCNA, a huge rocket that is theoretically capable of delivering a nuclear warhead to the United States mainland.
Kim commended the officials who developed the new missile in his comments.
He called the missile “the world’s strongest strategic weapon” and said it represented “a wonderful leap forward in the development of the technology of mounting nuclear warheads on ballistic missiles”.
With the development of the new ICBM, Kim said North Korea had demonstrated to the world “the confident, ever-victorious future of our state advancing toward the goal of building the world’s strongest army”.
In a letter sent to Kim recently, scientists from North Korea’s Academy of Defence Science said the test firing marked a “great historic victory” for the country and demonstrated North Korea’s sovereignty.
