Russia’s space-based missile early-warning constellation may be down to a single functioning Tundra-class satellite by the end of 2025, according to the Russian Strategic Nuclear Forces blog on December 28.
The blog, citing publicly tracked orbital behavior, said object “Cosmos-2541” has not shown signs of routine orbit-correction maneuvers since one carried out in March 2025, while object “Cosmos-2563” appears to have failed after its last successful maneuver in July 2025.

It said “Cosmos-2552” was the only spacecraft of the three that did not show clear signs of failure, though it had not performed an orbit correction that earlier patterns would have suggested around November 2025.
The Tundra satellites are part of Russia’s EKS/Kupol early-warning program, using infrared sensors in highly elliptical orbits to detect ballistic missile launches and feed data into Russia’s broader warning architecture alongside ground-based radars.
Earlier, it was reported that Russia declared European satellites assisting Ukraine’s military to be legitimate targets, citing their support for Ukrainian battlefield operations.
