USA-276, also known as NROL-76, is a classified spacecraft operated by the National Reconnaissance Office.[3] Due to being classified, very little information is known about the satellite.[4]
Background
USA-276 was launched onboard Falcon 9 NROL-76.[1] The Falcon 9 upper stage that carried USA-276 to its orbit made several close flybys of the ISS.[4]
