The aircraft strengthened the air power of Su-27s and MiG-31s providing fighter cover to troops and ground facilities from "enemy" aircraft. Multifunctional Su-35 fighters equipped with medium-range missiles are used to gain air superiority by eliminating manned and unmanned flying vehicles.
"Su-27 (Flanker) multi-function jets and MiG-31 (Foxhound) interceptor jets participated in air combat attacks against Su-25 (Frogfoot) jets simulating enemy aircraft," the Eastern Military District said in a statement.
After warding off the attack and performing advanced aerobatics the aircraft landed at a tactical airfield.
Approximately 500 servicemen and over 30 fighter jets are taking part in the drills, which will end on April 11. The Russian Defense Ministry has announced plans to conduct at least 4,000 military exercises throughout the country in 2015.
