1979
Adolf Tolkachev espionage case
Adolf Tolkachev, described as a former chief designer associated with the organization, passed classified information to the CIA over the period from 1979 to 1985. The information concerned Soviet missiles, air-defense systems, aircraft radars, and avionics, including programs connected with the MiG-29, MiG-31, and Su-27. The available source does not establish that Phazotron-NIIR as an institution participated in the espionage.
