Summary of Measures Taken Regarding Observations of Flying Projectiles

This document outlines the administrative and operational measures taken by the Swedish Armed Forces in response to reports of unidentified flying projectiles. The process began with the compilation and analysis of incoming reports by the Defense Staff (Försvarsstaben), with personnel dispatched for further investigation when deemed necessary. On July 11, the public was encouraged via the press to report sightings, while the news agency TT was instructed not to disclose specific observation locations. The Defense Staff issued orders to all military units to observe and report phenomena potentially related to flying projectiles, with similar instructions later extended to the Pilotage Service (Lotsverket) and Customs (Tullen). The Air Force initiated radar surveillance on July 24, which continued with varying intensity until September 14, and resumed on November 6. Due to personnel shortages and equipment limitations, continuous 24-hour monitoring was not possible, though a fighter flight was kept on alert and the 'East' fighter control center was activated during a period of heightened surveillance between August 24 and September 3. Aerial surveillance was also conducted over the southern Baltic Sea. The National Defence Radio Establishment (FRA) maintained continuous monitoring using standard equipment. Additionally, two B3 aircraft were equipped with recording apparatus to assist FRA in monitoring the Baltic Sea. The Air Administration (Flygförvaltningen) was tasked with identifying Swedish institutions and firms possessing equipment capable of generating impulse-type signals to support FRA's efforts. Finally, the Navy established a major radar station at Mälsten.
