scientists and military experts confirmed that russian orbital systems are actively jamming gps signals from space, with potential costs to infrastructure measured in hundreds of billions and vulnerabilities extending to power grids, communications, and financial systems. separately, nato's baltic sentry operation reduced undersea cable sabotage response time from 17 hours to 1 hour over the past year — a significant operational improvement in a layer that had seen repeated incidents. these two signals together show the infrastructure layer is simultaneously hardening in one theater and being actively degraded in another.
