Cold War Satellite Program Declassified

The National Reconnaissance Office (NRO) has recently made public a previously classified satellite program from the Cold War, designed to monitor Soviet military communications.

Known as Jumpseat, this satellite was a pioneering signal-gathering system that operated in a highly elliptical orbit from 1971 to 1987. It was developed by the NRO in collaboration with the United States Air Force (USAF). According to a January 28th news release from the NRO, the program played a significant role in U.S. intelligence efforts during a tense historical period.

Dr. James Auzen, who directs the NRO National Reconnaissance Research Center, remarked, “The historical significance of JUMPSEAT cannot be underestimated. The orbit provided the United States with a new vantage point for collecting unique and important signals information from space.”

Jumpseat was initiated as part of “Project EARPOP,” aiming to enhance intelligence-gathering capabilities during persistent Cold War anxieties.

The first launch occurred from Vandenberg Space Force Base, formerly Vandenberg Air Force Base, in California in 1971. The satellite effectively captured various electronic signals, including communications intelligence.

This data was subsequently shared with national security agencies like the Department of Defense and the National Security Agency (NSA).

In a memo dated December 5, 2025, NRO Director Chris Scoleese explained that “publicly acknowledging limited facts does not harm current or future satellite systems.” He emphasized that being transparent about this satellite program aligns with their commitment to openness regarding past initiatives.

Although aspects of the JUMPSEAT program had been known since the 1980s, many specific details remained obscure until this recent declassification, as noted by Air & Space Forces Magazine.
