Specifically, the plant in the first half of 2017 tested flight Su-22M4 5866, Su-22UM3K aircraft No. 8511 for timely units for combat readiness and training; The Technical Council has checked and waited for the 5870 aircraft to be handed over.

In particular, the plant is performing major repairs, increasing the total to over 30 years of Su-22M4 5874 aircraft reached 60% of the plan, Su-22UM3K aircraft number 8514 reached 50% of the plan; Repair of equipment and spare parts for aviation reached 87% of the year plan … 

Sukhoi JSC, Sukhoi JSC, Su-22M4 and Su-22M3/UM3K fighter aircrafts have an annual flying time of 2,000 hours, based on a 20-year number. Moved to Vietnam in the period 1970-1980, to date, most of the Su-22 fighter-bomber versions of various versions serving in the Vietnam National Park have almost reached the end of their life. Some Su-22M and UM aircraft have retired, with the rest being more modern versions of the Su-22UM3K and Su-22M4.

The Su-22 identifies the export version of the Su-17 fighter-bomber series served in the Soviet Air Force. Currently, in Southeast Asia, Vietnam is the only country to own the Su-22, and is also the only country equipped with airplanes with winged wings. The design of the wing allows the aircraft to fly low-speed at high speed or high-speed over the sound of the ceiling. When the wings spread out, the lift of the wings increased, allowing the aircraft to take off the short runway.
