In the coming weeks, Washington, Beijing, and other capitals need to pressure Putin to abandon any ideas about putting nuclear weapons in orbit. As President Joe Biden noted on Feb. 16, that deployment “hasn’t happened yet, and my hope is it will not.”

Fifty-seven years ago, through the Outer Space Treaty, the United States and the Soviet Union agreed to codify a fundamental nuclear taboo: nuclear weapons shall not be stationed in orbit or elsewhere in outer space. But there is growing concern that Russia is working on an orbiting anti-satellite (ASAT) weapons system involving a nuclear explosive device that would, if deployed, violate the treaty, undermine space security, and worsen the technological and nuclear arms race.
The White House confirmed on Feb. 15 that U.S. intelligence uncovered evidence that Russia is developing an ASAT weapon that “would be a violation of the Outer Space Treaty, to which more than 130 countries have signed up to, including Russia.” Russian President Vladimir Putin issued a nondenial denial, claiming on Feb. 20 that Russia remains “categorically against…the placement of nuclear weapons in space.”
An ASAT system involving a nuclear explosive device could produce a massive surge of radiation and a powerful electromagnetic pulse that, depending on the altitude of the explosion and the size of the warhead, could indiscriminately destroy, blind, or disable many of the 9,500 commercial and military space satellites now in orbit.
