Russian Air Defense Novosibirsk Radar UAP 1993

On May 18, 1993, Russian Air Defence Forces radar at the Novosibirsk Air Defence Sector detected an unidentified contact at 60,000 feet performing a stationary hover over central Siberia. The contact was tracked for 25 minutes on multiple radar stations in the Novosibirsk sector. When the contact departed, radar operators measured the acceleration as approximately Mach 5 — beyond the performance of any known aircraft in Russian or foreign inventory. Interceptors were not scrambled as the contact was above the operational ceiling of available aircraft. Russian Air Defence classified the report immediately. After the dissolution of the Soviet Union in 1991, Russia established a successor scientific committee within the Ministry of Defence that continued evaluating UAP reports from Russian military units. The 1993 Novosibirsk case was included in the committee's database. The encounter represents the continuity of the documented UAP problem through the Soviet-Russian transition period.
