The Su-35 is one of Russia’s most advanced combat aircraft, used for air superiority missions and strikes against Ukrainian targets.
The announcement follows a June 26 strike on Russian-occupied Crimea that destroyed a Russian MiG-29 fighter jet at Belbek airfield, Ukraine’s Main Intelligence Directorate (HUR) reported on July 4.
The agency estimated the financial losses incurred by the Russian military from this incident to be in the tens of millions of dollars.
As of Wednesday, Russia has lost 436 aircraft and 353 helicopters in its war against Ukraine, according to Ukraine’s General Staff.
Previous deliveries
In December 2025, Russia’s United Aircraft Corporation (UAC) reported it had delivered a new batch of Su-35S multirole fighters to the Russian military; however, did not specify how many.
The Su-35S (NATO reporting name: Flanker-E) is a Russian multirole fighter jet, an upgraded version of the Su-27 Flanker developed in the 1980s and in service since 2014.
The last known delivery – the sixth batch – was in November 2025, according to a Russian aviation outlet, suggesting the latest shipment marks the seventh batch. The outlet estimated that 15 to 18 Su-35S jets were delivered in 2025, while total deliveries in 2024 were 15 aircraft across four batches.

Russia reportedly licensed Iran to build the Su-35S jets as part of a bilateral military exchange.
Last week, Russia reportedly completed production of the first batch of 20 Su-35 fighters ordered by Iran, marking a major step in Tehran’s effort to modernize its aging air force.
According to Military Watch Magazine, the aircraft were built at Russia’s Komsomolsk-on-Amur Aviation Plant, with Iran’s defense ministry covering maintenance and sustainment costs while the jets remain in Russia ahead of transfer.
The development follows leaked Russian military-industrial correspondence from late 2025 indicating that 16 Su-35s were already in production for Iran at the time.
