As of September 2022, Cosmos 2558 had altered its orbit to continue matching the orbital plane of USA 326 while not being in an actual proximity orbit.
Object C reached a closest point of approach of 58 kilometers to USA 326 on July 19, 2025, having earlier closest approach distances of about 76 kilometers.
Cosmos 2558 initially occupied an orbit with an orbital plane similar to USA 326, a classified NRO imagery satellite launched in February 2022.
Kosmos-2558 was launched approximately six months after USA 326, indicating the potential for timely targeting.
Cosmos 2558 launched into a similar orbit in 2022 and subsequently raised its orbit to make close approaches to USA 326, a U.S. reconnaissance satellite.
