Post-SDI Missile Defense

Two days after North Korea’s missile launch in May 2017, the US successfully tested its national missile defense system. This was the first hit in almost 3 years. It was also the first time that the system was tested against an ICBM-class target. Ground-based Midcourse Defense (GMD) has cost $123 billion since 2002, with nine out of 18 successful tests since 1999—exactly 50%.
