But the organization promises not to deploy any weapons.
Plead the Fifth
Prior to this week, the North Atlantic Treaty Organization (NATO) — a military alliance between 29 European and North American nations — operated in four domains: air, land, sea, and cyberspace.
But on Wednesday, Jens Stoltenberg, NATO’s secretary general, announced the organization's intention to add a fifth "operational domain" to its purview: space.
Case for Space
During a meeting in Brussels, Stoltenberg told reporters that NATO will begin taking action to protect its members' interests in space.
"Space is extremely important for all civilian and military activities, for communications, for navigation, for the transmission of data, so of course space and satellites are of great importance for all NATO Allies," he said. "We will not weaponise space, we will not deploy weapons in space, but we make sure that the assets there are available in peace, crisis and conflict."
NATO's decision to make space an operational domain aligns with the activity of several nations, both within and outside of the treaty.
In August, the United States launched the U.S. Space Command to oversee its off-world military operations. A month prior, French Defense Minister Florence Parly announced that the nation was developing anti-satellite weapons to protect its interests in space. And earlier in 2019, the Pentagon reported that both Russia and China were building their own space weapons.
Given those developments, NATO might not plan to weaponize space. But if backed into a corner, it might not have much of a choice.
