The Congressional defense budget process is entering its conclusion, though battles remain. Despite little to show for it, the overall budget for missile defense continues to be robust. For example, the Senate appropriators met last week and added $1.2 billion above the Trump administration’s budget request for missile defense, including an additional $532 million for upgrades and six more boosters for the beleaguered Ground-based Midcourse Defense system, and added $222 million to fund program to replace the recently canceled Redesigned Kill Vehicle program. That is an unfortunate waste of tax dollars.

However, in other areas Congress—in particular the House—made a number of useful and positive corrections to the administration’s $9.4 billion missile defense budget request. The House also put several sensible new missile defense policies in place that deserve support. Read more >

, 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

Questions about a US Space Force

, 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.”

The term “Space Force” really got everyone’s attention. Obviously, everyone wants to know what the uniform would be. And the whole idea is built for memes.

What’s it all about? Let me respond to three different kinds of questions I’ve been hearing about this. Read more >
