About this Unit
The 6594th Test Group was a highly specialized unit of the United States Air Force, established in 1958 and based at Hickam Air Force Base, Hawaii. Its primary mission was the recovery of film canisters ejected from reconnaissance satellites, such as those from the Corona program, during the early years of space-based intelligence gathering. Using specially modified JC-130 aircraft, the unit performed daring mid-air retrievals of sensitive payloads descending by parachute over the Pacific Ocean. The 6594th Test Group’s operations played a crucial role in advancing American strategic reconnaissance capabilities during the Cold War, before being inactivated in 1986.
Historical Facts
•
Secretive Mission: The 6594th Test Group was an extremely secretive United States Air Force unit, tasked with the mid-air recovery of film canisters ejected from reconnaissance satellites, especially the CORONA program during the Cold War.
•
Based in Hawaii: The group was based at Hickam Air Force Base in Hawaii, strategically located to recover descending film canisters over the Pacific Ocean.
•
“Catchers in the Sky”: The unit became known as the “Catchers in the Sky” for their unique mission of catching parachuting satellite payloads mid-air using specially equipped aircraft.
•
Equipped Aircraft: The 6594th primarily used JC-130 Hercules aircraft, modified with special recovery equipment including large hooks to snatch parachutes from the sky.
•
Challenging Recoveries: Recovery missions were dangerous and required precise flying, as the canisters descended at high speeds and could land in the vast ocean if not caught.
•
Key Role in Intelligence: The success of the 6594th was crucial to America’s satellite reconnaissance efforts, providing critical intelligence during the height of the Cold War.
•
Rescue Missions: The unit also participated in search and rescue operations, notably saving 27 people in 1972 after a United Airlines flight crash-landed in the Pacific.
•
Decorated Unit: The 6594th Test Group and its members received numerous awards and commendations, including Air Force Outstanding Unit Awards and humanitarian recognition.
•
Disbandment: The unit was officially inactivated in 1986, as satellite technology improved with digital transmission, making film recovery obsolete.
•
Legacy: In 2015, the National Reconnaissance Office declassified the mission of the 6594th, revealing their remarkable contributions to national security and the advancement of aerial and space reconnaissance.
