The 26th Space Aggressor Squadron is a United States Air Force unit stationed at Vandenberg Space Force Base, California. Established in 1959 as part of the NASA's Manned Orbiting Laboratory program, the squadron now operates under the 30th Space Wing to provide realistic adversary simulations for space and missile warfare exercises. The squadron's primary role is to ensure the readiness of U.S. forces through training and development of countermeasures against potential threats in the space domain. The 26th SAS employs a variety of simulated threat systems, such as satellites, missiles, and other space objects, to challenge and prepare U.S. forces for various operational scenarios.
