Referring to data tracking objects in Earth's orbit, the scientist said that as early as March, Project Tundra had three early warning satellites operating, but by the end of 2025, only one is likely to be operational – launched in November 2021.”Space 2552″.
“It shows no obvious signs of malfunction,” the author writes about it.
According to Podvig, the orbit of the Cosmos 2541 satellite (launched in September 2019) was last adjusted back in March, and the orbit of Cosmos 2563 (launched in November 2022) was adjusted in July. At “some point” they failed.
“The apparent loss of early warning satellites is not necessarily a cause for alarm. Russia is not as dependent on the space segment of its early warning system as the United States,” he argues.
The Moscow Times notes that Russia has been creating the Tundra satellite constellation since 2015 instead of the Oko system, which has been in operation since the 1990s.
“The space segment of the Russian early warning system is in poor condition,” Podvig concluded.
