Russian spacecraft are trailing a US satellite used to spy on other countries, according to Gen John Raymond, the commander of the US Space Force, the Business Insider reports.
The two Russian satellites have come within 100 miles of the US satellite, and the US has raised concerns about the matter to Moscow through diplomatic channels, Raymond told Time magazine's W.J. Hennigan, who first reported the story on Monday.
In November, Russia launched "a satellite that subsequently released a second satellite," and the pair have been behaving similarly to a set that Russia previously labeled "inspector satellites," Raymond said.
He said "in any other domain," such a move "would be interpreted as potentially threatening behavior."
The Russian Embassy in Washington, DC, did not respond to a request for comment.
The confrontation marks the first time the US military has publicly identified a direct threat to a specific American satellite by an adversary.
Pentagon, White House and Congressional backers have said that Russia's actions demonstrate the need for the Space Force, which became the sixth military branch when President Donald Trump signed the $738billion National Defense Authorization Act into law in December.
