A batch of generation 4++ Su-30SM fighter jets with the upgraded turbojet engine will arrive for the air regiment stationed in the Tver Region in west Russia in 2021, the press office of Russia’s Western Military District reported on Monday. This reported by TASS.

"The fighter regiment of the Western Military District will get a batch of Su-30SM fighters under the state defense procurement plan with the upgraded engine. The first batch is planned for delivery in 2021. The new fighters are set to be outfitted with the latest AL-41F-1S engines," the press office said, without specifying the number of fighter jets in the batch.

The Su-30SM is being upgraded by the Irkut Aircraft Corporation and the Sukhoi Design Bureau on the assignment of Russia’s Defense Ministry in association with leading Russian defense enterprises. The upgrade will boost the fighter’s combat capabilities: it will increase the range of detecting and identifying air targets and furnish the plane with new precision weapons to hit air, ground and sea targets at a range of several hundred kilometers.
