Russian Aerospace Forces received a new batch of Su-35S fighters As PJSC United Aircraft Corporation (PJSC UAC, part of Rostec State Corporation) reported on December 3, 2022, the Yu.A. Gagarin (KnAAZ) in Komsomolsk-on-Amur manufactured and handed over to the Russian Aerospace Forces another batch of new Su-35S aircraft. The 4++ generation multifunctional fighters Su-35S passed a cycle of ground and flight tests in various operating modes and flew from the KnAAZ airfield to the place of duty.
bmpd's comment. Judging by the video circulated by the UAC, four new Su-35S fighters built by KnAAZ were delivered to the Russian Aerospace Forces. Aircraft side numbers on common video and photo materials are retouched.
Presumably, these are the first four Su-35S fighters manufactured under the fourth contract concluded in 2021 by UAC for the supply of Su-35S aircraft to the Russian Ministry of Defense. It is possible that this contract includes 22 aircraft for delivery by 2024.
These four Su-35S fighters are also the second batch of aircraft of this type built by KnAAZ in 2022, which is consistent with previously released information, according to which KnAAZ should hand over seven Su-35S fighters to the Russian Aerospace Forces in 2022.
Earlier, on September 9, KnAAZ delivered the first three Su-35S fighters of its 2022 production program. These three Su-35S aircraft with blue tail numbers "01", "02" and "03" became the final aircraft under the third contract with UAC concluded on August 25, 2020 during the Army-2020 International Military-Technical Forum by the Russian Ministry of Defense for the supply of eight Su-35S fighters.
These three Su-35S entered the 116th Combat Training Center of the 185th Center for Combat Training and Combat Use of Fighter Aviation of the Russian Aerospace Forces at the Privolzhsky airfield in the Astrakhan region, becoming the first Su-35S aircraft as part of this Center.
Earlier in 2021, KnAAZ handed over the first five Su-35S aircraft under this 2020 contract (the first three of them were handed over on December 13, 2021, and two more - presumably at the end of December).
Prior to that, under two previous contracts in 2009 and 2015, the Russian Aerospace Forces received 98 serial Su-35S aircraft from 2012 to 2020, two of which have now been decommissioned or lost by early 2022. Thus, the total number of serial Su-35S received by the Russian Ministry of Defense, now, with the delivery of four more aircraft under the new contract, should reach 110 units.
