North Korea announced on state television Tuesday night that it had tested a new type of mobile-launched intercontinental ballistic missile (ICBM), called the Hwasong 15, that it said was capable of carrying a nuclear warhead to the mainland United States. U.S. intelligence analysts are looking at the test, including the possibility it could have been a three-stage missile.
Announcers described the new missile as being “significantly more" powerful than the two Hwasong 14 ICBM’s North Korea launched in July.
According to three U.S. officials, U.S. intelligence agencies are still carrying out an analysis of Tuesday’s missile launch and they say it could be weeks before a final determination can be made if it is a new type of missile.
One official said initial information indicated the North Korean missile may have consisted of three stages during its boost phase. That would be a different type of missile from the two ICBM's fired in July that were two-stage missiles. Several officials said analysts are continuing to assess how different the missile launched Tuesday may have been from the earlier ICBM's.
Initial U.S. assessments following Tuesday's launch described the missile as generally being what the U.S. calls a KN-20, or Hwasong 14, like the two ICBM’s launched in July.
The North Korean missile launched Tuesday reached an altitude of more than 2,700 miles and flew for 54 minutes. It traveled laterally for 590 miles before landing in the Sea of Japan, according to a U.S. official.
Flattening out the missile’s altitude gives it a trajectory of about 8,000 miles, according to Joe Cirincione, president of the Ploughshares Fund. With that reach the missile could hit every part of the Eastern seaboard of the United States.
“This thing could hit Cuba, it could hit Jamaica,” said Cirincione.
Those calculations are often done assuming a one-ton payload, but North Korea’s technology may have advanced to the point where they have a smaller warhead that weighs a half-ton, according to Cirincione.
"They're being provocative, they're testing us and they're running a kind of brinkmanship game," said Karako.
It took a day for North Korea to release photos of the nighttime launch, a slower timeline than earlier launches this year. Those images have helped U.S. intelligence determine North Korea’s missile capabilities.
Officials had said prior to Tuesday’s launch that there had been activity in North Korea consistent with earlier preparations for a missile launch.
