Silentbarker is a class of classified United States spy satellites for space domain awareness developed by US Space Force and National Reconnaissance Office.[1][2][3]
In December 2025, USSF System Delta 89 announced that it was seeking a new satellite to replace the series.[4] The USSF has also said it intends not to partner with the National Reconnaissance Office (NRO) for the replacement.[5]
