Soviet Air Defense Forces

The Soviet Air Defence Forces (Voyska Protivovozdushnoy Oborony, PVO Strany) were an independent branch of the Soviet Armed Forces from 1941 to 1991, dedicated to protecting Soviet airspace from strategic bombers, ballistic missiles, and other aerial threats. The PVO operated a continent-spanning radar network, interceptor aviation regiments, and surface-to-air missile units.

UAP-Related Role

PVO radar stations and interceptor regiments logged a substantial fraction of documented Soviet UAP encounters between the 1950s and 1991. Notable cases include the Pereslavl-Zalessky mass sighting (21 March), the Omsk radar-defeating sphere sighting, the Kapustin Yar rocket-depot intrusions, and the pilot intercept of two giant cigar-shaped UAPs accompanied by radar jamming. Because PVO tracking was connected to Soviet national-command authority systems, UAP events involving missile bases or rocket-test ranges received elevated reporting priority.

Archives

Fragmentary PVO UAP files were partially released to Russian researchers in the 1990s, primarily through the SETKA programme, and have been the subject of Western analysis by Nick Redfern, Paul Stonehill, and others. The PVO dissolved with the Soviet Union and was reorganised into the Russian Aerospace Forces structure.
