Washington's announcement marks the first time the U.S. has publicly confirmed the existence of a space weapon, breaking a long‑standing policy of silence. The move follows the 1967 Outer Space Treaty, which prohibits weapons of mass destruction in orbit, but leaves room for other types of military hardware. Meinke said the on‑orbit system is necessary to defend U.S. forces against hostile actions.
Experts fear the device could be an electronic‑warfare or radio‑jamming platform, capable of disabling rival satellites without creating debris. Dr Bleddyn Bowen of the Royal United Services Institute described it as a non‑destructive anti‑satellite weapon that could neutralise satellite comms.
Russia, China and India have pursued similar capabilities, with Moscow and Beijing conducting rendezvous and proximity operations that could turn satellites into hunter‑killer platforms. China has demonstrated a space tug that can grapple and reposition satellites, a dual‑use tech that could also clear debris. Such manoeuvres blur the line between defence and offence in orbit.
The announcement has reignited fears of a new arms race, prompting calls from the UN Office for Outer Space Affairs for a renewed treaty. The U.S. is expected to brief the National Security Council on next steps later this week.
Meanwhile, operators of commercial satellites like Intelsat have raised alarms that jamming could cripple global communications.
