North Korea Test-Fires a Ballistic Missile Ahead of the G20 Summit
An Airline Crew Says It Saw North Korea's Latest Missile Test During a Commercial Flight · Fortune

North Korea said on Tuesday it successfully test-launched a first intercontinental ballistic missile, (ICBM), which analysts said could put all of the U.S. state of Alaska in range for the first time.

U.S. networks Fox News and NBC said U.S. officials had told them they believed Tuesday’s test was of an ICBM, marking a worrying milestone in Pyongyang’s missile development. CNN quoted officials as saying it was probably a two-stage ICBM.

The United States requested a closed-door meeting of the 15-member U.N. Security Council on the launch, a session likely to be scheduled for Wednesday, a spokesman for the U.S. mission to the United Nations said on Tuesday.

The launch, on the eve of U.S. Independence Day, took place days before leaders from the Group of 20 nations were due to discuss steps to rein in North Korea‘s weapons program, which it has pursued in defiance of Security Council sanctions.

North Korea‘s state media said the launch was ordered and supervised by leader Kim Jong Un and sent the Hwasong-14 933 km (580 miles), reaching an altitude of 2,802 km (1,741 miles) over a flight time of 39 minutes.

North Korea has said it is working to develop a nuclear-tipped missile capable of striking the U.S. mainland, something U.S. President Donald Trump vowed in January would never happen.

Some analysts said the flight details suggested the new missile had a range of more than 8,000 km (4,970 miles), which would put significant parts of the U.S. mainland in range, representing major advances in its program.

David Wright, co-director of the Global Security Program at the U.S.-based Union of Concerned Scientists, said the flight time and distance suggested the missile could travel about 6,700 km (4,163 miles), bringing all of Alaska into range.

South Korean President Moon Jae-in said the missile was believed to be an intermediate-range type, but the military was looking into the possibility it was an ICBM.

The Pentagon and State Department did not immediately respond to requests for comment on the TV network reports but said the U.S. government was working on a more detailed assessment of the launch. On Monday night, the Pentagon described the missile as an intermediate-range type that traveled for 37 minutes.

U.S.-based missile expert John Schilling, a contributor to the Washington-based North Koreamonitoring project, 38 North, said the launch was both earlier and “far more successful than expected.”

He said it would now probably only be a year or two before a North Korean ICBM achieved “minimal operational capability” and it was likely the initial test did not perform as well as an operational missile would.
