The top secret URSALA, RAQUEL, and FARRAH satellites

In short

Managed by the Secretary of the Air Force Special Projects office in Los Angeles, these low Earth orbit systems intercepted radar signals and gathered geolocation data under Mission 7300. Originally deployed as hitchhiker payloads from the sides of HEXAGON photo-reconnaissance spacecraft, the platforms later flew as secret space shuttle payloads. Although large antennas caused early models to burn up quickly from atmospheric drag, improved electronics eventually extended orbital lifespans and reduced the overall number of spacecraft required.

Stars in the sky: The top secret URSALA, RAQUEL, and FARRAH satellites from the 1970s to the 21st centuryby Dwayne A. Day

Satellites with names like URSALA, RAQUEL, FARRAH, GLORIA, and CARRIE have only recently been declassified, with significant information about them released only in the past two months, including the disclosure of previously secret space shuttle payloads. |

For the first decade, the various satellites under this program chased whatever new ELINT targets appeared and were of interest to the intelligence community. The satellites were designed to be inexpensive and simple enough to be developed in a year or less in response to new threats. Their payloads were often bespoke designs, built only once or twice before they were replaced by something else.

But by the 1970s, the National Reconnaissance Office (NRO), which managed the program, began to standardize the satellites and give them an operational mission supporting military forces around the world. Satellites with names like URSALA, RAQUEL, FARRAH, GLORIA, and CARRIE have only recently been declassified, with significant information about them released only in the past…
