Viktor Belenko
Soviet MiG-25 pilot who defected to the West

Viktor Ivanovich Belenko (Russian: Виктор Иванович Беленко; February 15, 1947 – September 24, 2023) was a Soviet-born American aerospace engineer and pilot who defected in 1976 to the West while flying his MiG-25 "Foxbat" jet interceptor and landed in Hakodate, Japan. George H. W. Bush, the Director of Central Intelligence at the time, called the opportunity to examine the plane up close an "intelligence bonanza" for the West. Belenko later became a U.S. aerospace engineer.
Early life and defection
Belenko was born in Nalchik, Russian SFSR, in a Russian family (his passport states his ethnicity as Russian). Lieutenant Belenko was a pilot with the 513th Fighter Regiment, 11th Air Army, Soviet Air Defence Forces based in Chuguyevka, Primorsky Krai. On September 6, 1976, he successfully defected to the West by flying his MiG-25 jet fighter to Hakodate Airport in Hokkaido, Japan. He was married to Lyudmila Petrovna and they had a son, Dmitry (born in January 1973), but at the time of his defection, he was going through a marital crisis, when his wife, hailing from a wealthy family and not liking being a military wife, had told him she was intending to file for divorce and move with their son to her parents' home in Magadan.
This was the first time that Western military intelligence were able to get a close look at the aircraft and its specifications, and many secrets and surprises were revealed. His defection caused significant damage to the Soviet Air Force. Belenko was granted asylum by U.S. President Gerald Ford, and a trust fund was set up for him, which granted him a very comfortable living in later years.
This brief starts where responsible research should: with the source description of “Viktor Belenko” as soviet MiG-25 pilot who defected to the West. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as soviet MiG-25 pilot who defected to the West. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q504070. VIAF identifies the subject as 56149366318985602255. The Library of Congress control number is n79090902. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1947, 2023, 1976 and 1973.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
