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. There is not always a one-to-one mapping between launch vehicles and mission spacecraft. This can occasionally result in gaps when maintaining records that incorrectly make that assumption, such as the "missing" entries for USA-163 (which are, symmetrically, contemporary with confusion over "splitting" spacecraft tracks).

Pegasus is an air-launched launch vehicle developed by Orbital Sciences Corporation (OSC) and now built and launched by Northrop Grumman. Pegasus is the world's first privately developed orbital launch vehicle. Capable of carrying small payloads of up to 443 kg (977 lb) into low Earth orbit, Pegasus first flew in 1990 and remains active as of 2021. The vehicle consists of three solid propellant stages and an optional monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately 12,000 m (39,000 ft), and its first stage has a wing and a tail to provide lift and altitude control while in the atmosphere. Notably, the first stage does not have a thrust vector control (TVC) system.
Orbital Sciences Corporation was an American company specializing in the design, manufacture, and launch of small- and medium- class space and launch vehicle systems for commercial, military and other government customers. In 2014, Orbital merged with Alliant Techsystems to create a new company called Orbital ATK, Inc., which in turn was purchased by Northrop Grumman in 2018. The remnants of the former Orbital Sciences Corporation became a subsidiary of Northrop Grumman, known as Northrop Grumman Space Systems.
Space Exploration Technologies Corp., commonly referred to as SpaceX, is an American spacecraft manufacturer, launch service provider, defense contractor and satellite communications company headquartered in Hawthorne, California. The company was founded in 2002 by Elon Musk with the goal of reducing space transportation costs and ultimately developing a sustainable colony on Mars. The company currently operates the Falcon 9 and Falcon Heavy rockets along with the Dragon and Starship spacecraft.
Atlas V is an expendable launch system and the fifth major version in the Atlas launch vehicle family. It was originally designed by Lockheed Martin, now being operated by United Launch Alliance (ULA), a joint venture between Lockheed Martin and Boeing. It is used for DoD, NASA, and Commercial payloads. It is America's longest-serving active rocket. After 87 launches, in August 2021 ULA announced that Atlas V would be retired, and all 29 remaining launches had been sold. As of January 2024, 17 launches remain. Other future ULA launches will use the new Vulcan Centaur rocket.
United Launch Alliance, LLC, commonly referred to as ULA, is an American aerospace manufacturer, defense contractor and launch service provider that manufactures and operates rockets that launch spacecraft into Earth orbit and on trajectories to other bodies in the Solar System. ULA also designed and builds the Interim Cryogenic Propulsion Stage for the Space Launch System (SLS).
The Minotaur I, or just Minotaur is an American expendable launch system derived from the Minuteman II missile. It is used to launch small satellites for the US Government, and is a member of the Minotaur family of rockets produced by Orbital Sciences Corporation.
Antares, known during early development as Taurus II, is an expendable launch system developed by Orbital Sciences Corporation and the Pivdenne Design Bureau to launch the Cygnus spacecraft to the International Space Station as part of NASA's COTS and CRS programs. Able to launch payloads heavier than 8,000 kg (18,000 lb) into low Earth orbit, Antares is the largest rocket operated by Northrop Grumman. Antares launches from the Mid-Atlantic Regional Spaceport and made its inaugural flight on April 21, 2013. Antares 100 was retired in 2014 and series 200 was retired in 2023 due to component unavailability. As of January 2024 Antares 300 is under development.
Cygnus is an expendable American cargo spacecraft developed by Orbital Sciences Corporation but manufactured and launched by Northrop Grumman Space Systems as part of NASA's Commercial Resupply Services (CRS) program. It is usually launched by Northrop Grumman's Antares rocket from the Wallops Flight Facility, although three flights were on ULA's Atlas V and three are planned for SpaceX's Falcon 9, in both cases launching from Cape Canaveral Space Force Station. It transports supplies to the International Space Station (ISS) following the retirement of the American Space Shuttle. Since August 2000, ISS resupply missions have been regularly flown by the Russian Progress spacecraft, as well as by the European Automated Transfer Vehicle, and the Japanese H-II Transfer Vehicle. With the Cygnus spacecraft and the SpaceX Dragon, NASA seeks to increase its partnerships with domestic commercial aviation and aeronautics industry.
The Space Tracking and Surveillance System was a pair of satellites developed by the United States Missile Defense Agency (MDA) to research the space-based detection and tracking of ballistic missiles. Data from STSS satellites could allow interceptors to engage incoming missiles earlier in flight than would be possible with other missile detection systems. The STSS program began in 2001, when the "SBIRS Low" program was transferred to MDA from the United States Air Force. In December 2002, SBIRS Low Research & Development was renamed Space Tracking and Surveillance System (STSS).
The Space Based Space Surveillance (SBSS) system is a planned United States Space Force constellation of satellites and supporting ground infrastructure that will improve the ability of the United States Department of Defense (DoD) to detect and track space objects in orbit around the Earth.
On-orbit satellite servicing refers to refueling or repairing space satellites while in orbit.
Northrop Grumman Innovation Systems (NGIS) was a sector of Northrop Grumman from 2018 to 2019. It was formed from Orbital ATK Inc. a company which resulted from the merger of Orbital Sciences Corporation and parts of Alliant Techsystems in 2015. Orbital ATK was purchased by Northrop Grumman in 2018. Northrop Grumman Innovation Systems designed, built, and delivered space, defense, and aviation-related systems to customers around the world both as a prime contractor and as a merchant supplier. It had a workforce of approximately 12,000 employees dedicated to aerospace and defense including about 4,000 engineers and scientists; 7,000 manufacturing and operations specialists; and 1,000 management and administration personnel. With Northrop Grumman's reorganization of its divisions effective January 1, 2020, NGIS was split, with most of the sector merging with other Northrop Grumman businesses into a new Space Systems sector.
NG-10, previously known as OA-10E, is the eleventh flight of the Northrop Grumman uncrewed resupply spacecraft Cygnus and its tenth flight to the International Space Station under the Commercial Resupply Services (CRS-1) contract with NASA. The mission launched on 17 November 2018, at 09:01:31 UTC. This particular mission is part of an extension of the initial CRS contract that enables NASA to cover the ISS resupply needs until the Commercial Resupply Services-2 (CRS-2) contract enters in effect.
OmegA was a medium-lift to heavy-lift launch vehicle concept that spent several years in development by Northrop Grumman during 2016–2020, with that development substantially funded by the U.S. government. OmegA was intended for launching U.S. national security satellites, as part of the U.S. Department of the Air Force National Security Space Launch (NSSL) replacement program.
USA-280 was a classified United States government satellite that was launched by SpaceX on 8 January 2018, on the 47th flight of the Falcon 9 rocket. The National Reconnaissance Office was in charge of the Zuma project, though its purpose has not been disclosed. In November 2017, Northrop Grumman stated that the launch "is a monumental responsibility and has taken great care to ensure the most affordable and lowest risk scenario for Zuma." The Wall Street Journal reported that the design was very sensitive to vibration and sudden shocks, and had a development cost approaching US$3.5 billion.
Cygnus NG-16, previously known as Cygnus OA-16, was the sixteenth flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its fifteenth flight to the International Space Station (ISS) under the Commercial Resupply Services (CRS-2) contract with NASA. The mission was launched on 10 August 2021 at 22:01:05 UTC, for a (planned) 90-day mission at the ISS. This was the fifth launch of Cygnus under the CRS-2 contract.
