Space Command issued a condemnation later in the day Wednesday against the potential "threat" and "act of aggression," with SPACECOM chief Jay Raymond saying, "Russia's DA-ASAT test provides yet another example that the threats to U.S. and allied space systems are real, serious, and growing," according to an official statement.

"The United States is ready and committed to deterring aggression and defending the nation, our allies, and U.S. interests from hostile acts in space," the statement said.

SPACECOM didn't specify where the ASAT weapon was aimed during the test, believed to have been a Nudol ballistic missile, and crucially indicated it wasn't tracking any debris.

Such tests are deeply controversial given they involve live targeting of an object in space, though it's believed the Kremlin has actually yet to be successful even after nine reported Nudol space missile tests going back to 2014.
