Sweden UFO Sighting, 1946 — FBI Files
A foo fighters era case from Sweden. In mid-1946, numerous people in Sweden reported seeing strange objects flying over the country.
Background
In 1946, in Sweden, U.S. government investigators recorded an unidentified-object incident later released to the public on May 8, 2026 as part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE). The incident is one of the foo-fighter-era reports from the Second World War, when allied aircrews repeatedly described unexplained luminous objects pacing their bombers. The case was filed with the Federal Bureau of Investigation, whose Knoxville, Albuquerque, Los Angeles, and other field offices routed UFO reports to headquarters under the Bureau’s standing protocols for the protection of vital installations.
What the document records
In mid-1946, numerous people in Sweden reported seeing strange objects flying over the country. Newspapers speculated these were Soviet guided missiles being tested, potentially originating from a former German experimental station or Dago Island. The Swedish defense staff investigated and may have intentionally promoted the missile theory for political reasons.
The number of witnesses is not specified in the released document.
Type of case
The case includes reports of figures or beings associated with the object.
Status
All records released under the PURSUE program are designated unresolved by the All-domain Anomaly Resolution Office (AARO) by default. The federal government has not concluded that the events were anomalous, has not concluded that they were conventional, and has not ruled out either possibility. Conventional candidates for sightings of this period include experimental aircraft, weather balloons (especially the Project Mogul series in the late 1940s), atmospheric optical phenomena such as sundogs and lenticular clouds, and astronomical objects including Venus, the Moon, and meteors near the horizon.
