No. 6173, 927th Fighter Regiment, Phúc Yên AB, Socialist Republic of Vietnam, 1979
As a compensation for destroyed MiG-21PFMs, the Vietnam Air Force received even this aircraft with a camouflage used in Soviet Air Force. Original
marking of the aircraft was repainted and substituted by Vietnamese national insignia and a red number 6173. The reason for marking the nose of the aircraft
by red stars is unclear. It could have meant the shot downs of enemy aircraft during the Vietnam War by Vietnamese pilots flying on specific planes. This
aircraft operated from Bien Hoa base and Da Nang base, it was part of 372nd Air Division.
