NATO to knit eight allies’ satellites into HALO space network

Eight NATO allies—Denmark, Canada, Finland, Germany, Norway, the Netherlands, Sweden and Turkey—will form the Hybrid Alliance Layered Operations in Space (HALO), a multi-nation satellite constellation to enable high-speed communications, intelligence and missile tracking by linking transport satellites, sensors and shared software/standards, with plans to expand; the effort aligns with NATO’s APSS program and other allied space initiatives, and mirrors related US Space Force concepts like the Space Data Network.
