, co-director and senior scientist

UPDATE: In September 2018, UCS released an animated feature and video that explains how space-based missile defense works. Check it out here.

Articles citing a classified 2011 report by the Institute for Defense Analysis (IDA) have mistakenly suggested the report finds that a constellation of only 24 satellites can be used for space-based boost-phase missile defense. Read More

, senior scientist

This week, President Trump verbally directed General Dunford, the Chairman of the Joint Chiefs of Staff, “to begin the process necessary to establish a Space Force as the sixth branch of the armed forces.”
