List of USA satellites. This is a list of satellites and spacecraft which have been given USA designations by the United States Air Force. These designations have been applied to most United States military satellites since 1984, and replaced the earlier OPS designation. As of June 2022, USA designations have been assigned to 331 space satellites.
Recent studies have proved that the "unintended electromagnetic radiation" affects radio telescopes creating distortions and excessive noise and the IAU Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference was created to manage these new man made obstacles to space exploration.

The large number of satellites employed by Starlink also creates long-term dangers of space debris collisions. [184] [185] However, the satellites are equipped with krypton-fueled Hall thrusters which allow them to de-orbit at the end of their life. They are also designed to autonomously avoid collisions based on uplinked tracking data.
The court in 2022 rejected a separate challenge to SpaceX's plan to deploy satellites at a lower Earth orbit than planned. In late 2022, the FCC approved SpaceX's request to deploy up to 7,500 ...
May 22, 2024 at 6:59 PM. By Joey Roulette. WASHINGTON (Reuters) - SpaceX on Wednesday launched an inaugural batch of operational spy satellites it built as part of a new U.S. intelligence network ...
The United States Space Surveillance Network (SSN) detects, tracks, catalogs and identifies artificial objects orbiting Earth, e.g. active/inactive satellites, spent rocket bodies, or fragmentation debris. The system is the responsibility of United States Space Command and operated by the United States Space Force and its functions are:
The National Reconnaissance Office ( NRO) is a member of the United States Intelligence Community and an agency of the United States Department of Defense which designs, builds, launches, and operates the reconnaissance satellites of the U.S. federal government. It provides satellite intelligence to several government agencies, particularly ...
This timeline of artificial satellites and space probes includes uncrewed spacecraft including technology demonstrators, observatories, lunar probes, and interplanetary probes. First satellites from each country are included. Not included are most Earth science satellites, commercial satellites or crewed missions .
