Honoring The Air Force Special Processing Facility

Deep Black on the West Coast (part 2): Honoring the Air Force Special Processing Facility by Dwayne A. Day Tuesday, May 26, 2026 On Friday, May 15, a ceremony was held on the grounds of the National Museum of the United States Air Force in Dayton, Ohio to dedicate a monument to the people who worked for a secretive organization on the West Coast. The Secretary of the Air Force Office of Special Projects, or SAFSP. But another group that was also technically part of SAFSP was left out of the ceremony. The new memorial does not mention the contributions of the 6594 Test Squadron Air Force Special Projects Production Facility (AFSPPF) based at Westover Air Force Base, Massachusetts, located on the other side of the country from SAFSP. AFSPPF was a tenant unit at Westover Air Force Base, and administratively supported by Hanscom Air Force Base, but it received guidance, direction and funding from SAFSP on the West Coast. It operated from 1961 to 1976. monument monument Photocopy and photo from a Performance Evaluation Team (PET) report on a late 1965 GAMBIT reconnaissance mission. The image shows a CORN reconnaissance target at a USAF base in the United States. The PET reports evaluated the camera performance for reconnaissance missions so that they could be improved in the future. They were produced by the AFFSPF in Massachusetts, and as were the teams that managed the CORN targets. (credit: NRO via Harry Stranger) The AFSPPF was an imagery facility and had three divisions that directly supported the National Reconnaissance Program. These were production, evaluation, and R&D. The production division had an original negative and duplicate film photo processing facility that handled CORONA, GAMBIT, HEXAGON, U-2 and D-21 TAGBOARD drone missions. Eastman-Kodak in Rochester, New York was the primary site for original negative production, with AFSPPF serving as backup. But AFSPPF also provided the bulk of dupe production for all US military and government mapping, charting, and geodesy organizations. Over its 15-year history the facility produced over 180 million feet (54.9 million meters) of film. The film was carefully inspected by highly trained Air Force quality control personnel for physical defects and image quality. monument A "challenge coin" presented at the recent dedication of the SAFSP memorial dedication.

They assessed the mission’s resolution, image quality, camera performance, and other mission aspects like the use of different film types. The PET produced a comprehensive report, and many such reports have now been declassified. Whereas intelligence reports indicated what was seen by the satellites, the PET reports indicated how well the mission performed in terms of the imagery, so that future missions could be improved. In addition, the Controlled Range Network (CORN) program deployed teams with resolution targets to various locations within the continental United States to provide image quality baselines during passes by satellites and was managed and directed by AFSPPF. AFSPPF was also designated and funded to seek out and evaluate emerging technologies in film processing, printing, and image quality evaluation. Promising technologies, materials, and chemistries were introduced into the facility and other processing facilities. monument A working model of the HEXAGON reconnaissance satellite camera system was shown at the recent dedication of the SAFSP memorial dedication. It is nicknamed “Fido.” Although it was left out of the new memorial, in 2014 a plaque mentioning AFSPPF was dedicated at the National Museum of the United States Air Force. The mission of the unit was partially revealed in 1995, and more completely in 2015. It may be the subject of a future article. Dwayne Day is interested in hearing from people who worked for SAFSP during the Cold War who can share what it was like to work for the secretive organization. He can be reached at zirconic1@cox.net.
