Some pretty good work by Congress on missile defense this year

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 >

No, Space-Based Missile Defense Will Not Cost Only $20 Billion. (Spoiler: That’s only the launch costs.)

Space-based missile defense is a terrible idea. It is expensive and straightforwardly defeated, and it is dangerous and destabilizing. (If you haven’t watched it, please do take a look at this video and web feature UCS just produced. It helps to see these arguments visually.)

But knowledgeable people say it’s not so expensive!

At a recent event hosted by the Missile Defense Advocacy, Under Secretary of Defense for Research and Engineering Mike Griffin calculated the cost to “put up” an interceptor layer. Given how Griffin talked about it, you may be forgiven for thinking he means this is the full cost of a space-based missile defense system—rather than just the cost of launching the interceptors into space.

Questions about a US Space Force

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 >

Lost in Space? The Zuma Satellite

Many people awaited last Sunday’s Falcon 9 launch from Cape Canaveral of a highly classified US payload. The launch had been delayed for weeks, speculation as to the satellite’s purpose was rampant, and successfully delivering national security satellites to orbit is an important part of SpaceX’s business.

The launch, however, remains shrouded in mystery. Read more >
