North Korea’s Longest Missile Test Yet

, former co-director

After more than two months without a missile launch, North Korea did a middle-of-the-night test (3:17 a.m. in Japan) today that appears to be its longest yet.

Reports are saying that the missile test was highly lofted and landed in the Sea of Japan some 960 km (600 miles) from the launch site. They are also saying the missile reached a maximum altitude of 4,500 km. This would mean that it flew for about 54 minutes, which is consistent with reports from Japan.

If these numbers are correct, then if flown on a standard trajectory rather than this lofted trajectory, this missile would have a range of more than 13,000 kilometers (km) (8,100 miles). This is significantly longer than North Korea’s previous long range tests, which flew on lofted trajectories for 37 minutes (July 4) and 47 minutes (July 28). Such a missile would have more than enough range to reach Washington, D.C., and in fact any part of the continental United States.

We do not know how heavy a payload this missile carried, but given the increase in range it seems likely that it carried a very light mock warhead. If true, that means it would be incapable of carrying a nuclear warhead to this long distance, since such a warhead would be much heavier.

No, Missile Defense Will Not Work 97% of the Time

, senior scientist

In an October 11 interview on Fox News, President Trump claimed:

We have missiles that can knock out a missile in the air 97 percent of the time. If you send two of them, they are going to get knocked down.

This is not true. At least not in any relevant way. Read more >

North Korea’s Sept. 15 Missile Launch over Japan

, former co-director

North Korea conducted another missile test at 6:30 am September 15 Korean time (early evening on September 14 in the US). Like the August 28 test, this test appears to have been a Hwasong-12 missile launched from a site near the Pyongyang airport. The missile followed a standard trajectory—rather than the highly lofted trajectories North Korea used earlier this year—and it flew over part of the northern Japanese island of Hokkaido (Fig. 1).

North Korea’s Missile Test over Japan

, former co-director

Yesterday’s missile launch by North Korea is reported to have been launched from a site near the capitol city of Pyongyang (Sunan) and landed 2,700 kilometers (km) (1,700 miles) to the east after flying over part of the Japanese island of Hokkaido. The missile reportedly flew to a maximum altitude of about 550 km (340 miles), reaching Hokkaido after about eight minutes of flight and splashing down after 14 to 15 minutes. Read more >
