US Spy Satellite Agency Declassifies High-Flying Cold War Listening Post
For decades, the US government's fleet of spy satellites has been shrouded in secrecy. However, the National Reconnaissance Office (NRO) has finally declassified a high-flying Cold War-era listening post known as Jumpseat.
Jumpseat was launched between 1971 and 1987, with its primary mission being to monitor Soviet military communication signals. The agency says that Jumpseat "collected electronic emissions and signals, communication intelligence, as well as foreign instrumentation intelligence." Data intercepted by the satellites flowed to the Department of Defense, the National Security Agency, and other national security elements.
The program was a precursor to more advanced US spy satellite programs in high elliptical orbit. The name Jumpseat was first revealed in 1986 by investigative journalist Seymour Hersh, who wrote that the satellites could intercept all kinds of communications, including voice messages between Soviet ground personnel and pilots.
According to declassified documents, Jumpseat carried a 13-foot antenna to intercept radio signals, somewhat smaller than prior estimates. The agency has not disclosed what specific signals were intercepted, but experts believe it was likely used to monitor Soviet radars and missile tests.
The declassification of the Jumpseat program is significant, as it provides insight into the US government's early efforts to gather intelligence on the Soviet Union during the Cold War. It also highlights the agency's commitment to transparency and open communication with the public.
In a statement, James Outzen, NRO director of the Center for the Study of National Reconnaissance, said that "the historical significance of Jumpseat cannot be understated." He noted that the program provided the US with a new vantage point for collecting unique and critical signals intelligence from space.
The declassification of Jumpseat follows similar releases of other Cold War-era spy satellites, including Corona and Hexagon. These programs shed light on the US government's early use of satellite technology to gather intelligence during the height of the Cold War.
