The US has new intelligence on Russian military capabilities related to its efforts to deploy a nuclear anti-satellite system in space, according to multiple sources familiar with the intelligence. The intelligence was briefed to Congress and key US allies, and some lawmakers say it is serious enough that it should be declassified and made public. While the intelligence is concerning, multiple senior members of Congress briefed on the information on Wednesday emphasized that it does not pose an immediate threat to the US or its interests. The system remains under development and is not yet in orbit, according to three US officials familiar with the intelligence. It’s not clear how far the technology has progressed, one of the officials said. A separate US official told CNN the threat does not involve a weapon that would be used to attack humans. It was not immediately clear whether the intelligence referred to a nuclear-powered, anti-satellite capability or a nuclear-armed capability. While members of Congress downplayed the immediacy of the threat, an anti-satellite weapon placed in orbit around Earth would pose a significant danger to US nuclear command and control satellites, said Hans Kristensen, director of the Nuclear Information Project at the Federation of American Scientists.
