Swedish Armed Forces — Ghost Rockets and modern UAP records
Försvarsmakten (Swedish Armed Forces)
Sweden's official UAP record begins with the 1946 'ghost rockets' wave — more than 2,000 reports of unidentified projectile-like objects over Scandinavia in the months immediately after WWII. The Swedish Defence Staff investigation file, declassified in stages from the 1980s, remains the most-cited Northern European UAP archive.
About the program
The ghost-rockets investigation was conducted by the Swedish Defence Staff in summer and autumn 1946, with active intelligence cooperation from the U.S. Army Air Forces and the British Air Ministry. More than 2,000 sightings were logged across Sweden, Finland, and Norway, with a substantial subset including radar tracks and recovered fragments. The file was classified at the time and only progressively declassified from the 1980s onward.
The Försvarsmakten's UAP record continued in a more diffuse form through the Cold War, with periodic high-profile incidents — most notably the recurring submarine-incursion / 'Hessdalen-style' light reports in the 1980s. Records are held by Riksarkivet (the Swedish National Archives) and accessible through its NAD finding-aid catalogue.
