The Kremlin placed its powerful fighter jets on combat alert as Russia’s large-scale military exercise, Vostok-2022, commenced Wednesday.

According to TASS, the Russian Defense Ministry ordered the Eastern Military District fighter aircraft—including crews of Su-35S, Su-30SM, and MiG-31—to be on combat alert at operational airfields in the Khabarovsk, Primorsky, and Kamchatka Regions and the Chukotka Autonomous Region.

The ministry stated that the fighter jets would practice intercepting aerial targets, providing cover for attack aircraft, carrying out air strikes against ground targets, and providing air support for troops during the drills.

“The crews of Su-35S, Su-30SM and MiG-31 fighters of the Eastern Military District went on air defense combat alert at operational aerodromes in the Khabarovsk, Primorsky and Kamchatka Regions and the Chukotka Autonomous Region as part of the Vostok-2022 strategic command and staff exercise,” the ministry said in a statement.
