SUMMARYU.S. Space Force chief Douglas Schiess said the branch operates on-orbit weapons to defend against space-enabled attacks, while officials outlined plans to expand space-based interceptors under the Trump administration’s Golden Dome missile defense effort. Reuters described the announcement as a milestone in space militarization amid U.S.-Russia tensions and renewed UN debates over banning weapons in orbit. The Congressional Budget Office estimated the space-based components of Golden Dome could cost up to $542 billion over 20 years.
Tuesday U.S. Space Force chief Douglas Schiess said his branch of the U.S. military operates "on-orbit weapons," reports Reuters, to defend "against space-enabled attacks." He promised "disciplined and responsible choices" when scaling America's orbital defense arsenal in the coming years.
NPR calls this week's reveleations "remarkable... after previous warnings about countries such as Russia possibly weaponizing a global frontier long agreed in treaties to be used for only peaceful purposes."
The revelation comes as the Trump administration puts a growing focus on space. In 2019, during his first term, Trump created the Space Force as a separate military branch. In his second term, he has announced the "Golden Dome" missile defense system, which includes plans to put U.S. weapons in space. Trump said last year that he expected the system would be "fully operational before the end of my term," which ends in January 2029, and have the capability of intercepting missiles "even if they are launched from space." Trump also has directed the Pentagon to pursue the space-based interceptors, in an executive order during the first week of his presidency. The Congressional Budget Office estimated that just the space-based components of the Golden Dome could cost as much as $542 billion over the next 20 years.
The Biden administration announced in 2024 that Russia was developing a space-based nuclear weapon that could loiter in space for long durations, then release a burst that would take out satellites around it. That kicked off a renewed debate on the idea of weapons in space at the United Nations. In April 2024, Russia vetoed a joint U.S.-Japanese resolution that would have called on all countries not to develop or deploy nuclear arms or other weapons of mass destruction in space, as banned under a 1967 international treaty that included the U.S. and Russia... The Russian delegation called the resolution hypocritical and a double standard and instead proposed a rival resolution to ban all weapons in space "for all time." It ultimately failed. Russia had argued that the United States and its allies opposed a ban on all weapons in outer space because they planned to deploy weapons there.
Reuters calls this "a landmark moment in space militarization," while noting that it's "aimed at deterring what U.S. officials describe as aggressive orbital activities from China and Russia, officials and analysts said."
The remarks this week by Washington's top military-space officials are part of "the increasing comfort level of the U.S. government to speak about aggressive actions in space" that has been building up in recent years, said Victoria Samson, chief director of space security and stability at the nonprofit Secure World Foundation. "We've gone from not talking about counter-space capabilities... to now saying flat-out we have weapons in space," Samson said. "The pendulum keeps on shifting over that way..."
"The acknowledgment of these space-control capabilities is fundamental to ensuring that we prevent deterrence from failing, and that we are postured and ready should deterrence fail to employ them effectively," Richard Palmer, the director of the Capability and Resource Integration Directorate at U.S. Space Command, said on Tuesday.... "The bottom line is that our joint force and our allied forces require space. Our economies require space," added Palmer. "We are ready in the U.S. to preserve that."
Reuters adds that Russia's Foreign Ministry issued criticism of America's move, saying "In pursuit of its narrow self-interests, Washington is ready to completely ignore the catastrophic consequences for humanity of any armed conflict in orbit."
