In August 2019, the Russian Defence Ministry first signed a contract for undisclosed number of modernized Su-30SM2 (then referred to it as Su-30SM1) fighters. First deliveries to the Russian Aerospace Forces are scheduled for late 2020 with serial deliveries to commence in 2021. The aircraft will receive the N035 Irbis radar and AL-41F1S engines of the Su-35S, what is to standardize and reduce operational costs of the two variants. The aircraft's armament will be also enhanced of the new KAB-250 aerial bombs and Kh-59MK2 stealth cruise missiles. It is planned to modernize all Russia's Su-30SMs to the SM2 standard.
