Sometimes, even when you’re No. 1, it pays to follow another’s lead. A case in point is the French Government’s recent announcement to develop bodyguard spacecraft to protect its satellites against Russian and Chinese robotic spacecraft capable of rendezvous and proximity operations (RPO). These spacecraft can repair and refuel satellites and remove space debris but also can operate in an offensive mode to disable satellites. France may not be the world’s largest space power but they are on to something here. Washington would be wise to work with Paris to turn France’s satellite protection plan into a NATO initiative at the NATO summit this December.

It would make perfect sense. In mid-July, French President Emmanuel Macron created a space command within the French air force to help protect French satellites. France’s defense minister, Florence Parly, on July 25 provided the key features of France’s new space strategy. The French plan is not only sound, it lashes up well with U.S. policy:

The French government believes that active defense is not an offensive strategy; that it is about self-defense. The French government says it will “reserve the time and means of the response.” The America First National Space Strategy unveiled by President Trump on March 23, 2018, says the same.

France shared its plans to develop small bodyguard spacecraft at the June 17-23, 2019 Paris Air Show. Scheduled for deployment beginning in 2023, these new French space bodyguards will carry cameras initially and may eventually carry active defensive weapons. This “vast and ambitious” French satellite protection program is expected to reach full capability by 2030. If the United States can decide now to develop its own bodyguard spacecraft, though, NATO could have an operational bodyguard system by the early 2020s when the robotic spacecraft threat will be on the upswing.

At the Air Show, Parly’s Ministry had an exhibit to illustrate “what space operations could be like in a few years.” France would have declared “space exclusion zone[s]in the GEO [geosynchronous] belt.” The Space Policy Directive-3, National Space Traffic Management Policy issued by President Trump on June 18, 2018, also mandates that “the United States should explore…common global best practices, including…a common process by which individual spacecraft may transit volumes used by existing satellites.” The guidelines released by DARPA’s Consortium for Execution of Rendezvous and Servicing Operations on Feb. 1, 2019 are even more explicit by suggesting “safety zones, and keep-out spheres or volumes for RPO and OOS [on-orbit satellite servicing] activities.”

Thus, what really separates the United States from France is whether and when to deploy bodyguard spacecraft. Hopefully, France’s announcement will not only convince its European partners but also motivate the United States to join its effort.

The United States is actively pursuing the idea of eliminating satellite vulnerability by using many small satellites to constitute follow-on space systems that are proliferated and redundant. Yet, full deployment of these satellite constellations cannot be completed before 2030 at the earliest. Some critical satellites, such as those for early warning of missile attacks and communications in a nuclear-disrupted environment, will remain vulnerable during the 2020s.

Bodyguard spacecraft designed to prevent offensive spacecraft from reaching or harming our satellites but that will not produce space debris are likely to be the only defense that could be ready in time, effective and non-escalatory against the robotic threat. Developing these spacecraft in conjunction with creating appropriate self-defense zones pushes back against the maximalist agendas of both military planners and arms controllers.

A major objection from military space officials about deploying bodyguard spacecraft is that initially they will be a single system that’s only able to counter a single threat — robotic spacecraft. These officials would rather develop powerful defensive and offensive weapons, such as long-range laser or interceptor systems, which could shoot down a variety of anti-satellite (ASAT) systems and other weapons. However, these systems would be too formidable to be considered a proportional response to the robotic threat and would likely trigger a space arms race that would not serve American interests. In any case, such systems will not be ready in time to deal with the robotic threat.

On the other hand, arms control officials and experts mistakenly insist that robotic spacecraft are too slow moving to be effective ASATs. They use this point to deny that there is a rapidly approaching threat and insist negotiating a comprehensive space treaty is the best way to go. This also is not quite right.

In fact, an adversary can legitimately station its robotic spacecraft arbitrarily close to our satellites in peacetime or even during a crisis. Then upon further command, they can move the last short distance to reach and disable our satellites without enough warning to allow us to defend our satellites. Also, tensions with China and Russia make reaching any major space treaty with either country to deal with the robotic threat in a timely manner very iffy.

What, then, is to be done?

France is in a good position to convince NATO’s European partners to endorse bodyguard deployment. France is the largest space power in Europe. It has been leading a Europe-wide effort to modernize space capabilities since 2010 and has joint space projects with Germany, Italy, Spain, Belgium, Greece and Sweden.

NATO is likely to officially declare space to be a warfighting domain at its summit in December. During the next few months, the United States should talk to NATO partners, especially France, about expanding France’s bodyguard program into a NATO initiative, including an effort to create appropriate self-defense zones around vulnerable but critical satellites, to be approved at the summit. In the meantime, Congress should conduct hearings to make clear the urgency and desirability of this initiative.
