John SchillingJohn Schilling is an aerospace engineer with more than twenty years of experience, specializing in rocket and spacecraft propulsion and mission analysis. Dr. Schilling received his Ph.D. in astronautical engineering from the University of Southern California, and spent most of his career as a contractor for the Air Force Research Laboratory’s Propulsion Directorate. When not studying the nuclear arsenals of foreign dictators, he currently works for the Aerospace Corporation as a specialist in satellite and launch vehicle propulsion systems.
In his 2017 New Year’s Address, Kim Jong Un mentioned (among many other things) that North Korea had “entered the final stage of preparation for the test launch of intercontinental ballistic missile.” It should be noted that this was neither the focus of his speech—which, for the most part, was a list of last year’s accomplishments—nor [...]

And they aren’t taking the slow path to developing a reliable system, with a year or so between each test to analyze the data and make improvements. That has [...]

They claimed this new engine had a thrust of 80 tons and would be use for a new space launch vehicle. Rocket engine thrust isn’t normally measured in “tons,” and there is some ambiguity [...]

However, this does not mean it will be ready next week, next month, or even next year. Rather, the pace and method of the North’s SLBM testing would suggest possible deployment in an [...]
“Even though the U.S. and its allies try to block our space development, our aerospace scientists will conquer space and definitely plant the flag of the DPRK on the moon!” What would have been alarming coming from a Cold War superpower seems almost comical coming from Pyongyang. Yet that was the recent claim from Hyon Kwang Il, director of [...]
