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 >

, co-director and senior scientist

In a previous post, I estimated what North Korea could have learned from its May 14 Hwasong-12 missile test that is relevant to developing a reentry vehicle (RV) for a longer range missile.

I’ve updated the numbers in that post for the July 4 missile test (Table 1). In particular, I compare several measures of the heating experienced by the RV on the July 4 test to what would be experienced by the same RV on a 10,000 km-range missile on a standard trajectory (MET). Read more >
