When SETKA ended in 1990–1991, Yuli Platov published findings in the Bulletin of the Russian Academy of Sciences: of roughly 3,000 cases analyzed over 13 years, over 90% were explained by rocket launches and balloons, while approximately 300 cases remained scientifically unresolved.

The published conclusion, 'Either the territory of the USSR was closed for alien visitations during at least 13 years, or the hypothesis of an extraterrestrial origin of UFOs is inconsistent', was drafted by the Academy of Sciences team, not the Ministry of Defense branch. The MoD's SETKA-MO conclusions were never made fully public. The surviving unresolved 10% constitutes the documented legacy of the Soviet state UAP investigation: a government program that ran longer and gathered more standardized military reports than any equivalent Western program of its era, and could not explain what it saw.
