Russia has completed production of the first batch of 20 Su-35 multirole fighter jets ordered by Iran, marking a significant milestone in Tehran’s efforts to modernise its air force amid heightened geopolitical tensions in the Middle East.
According to defence publication Military Watch Magazine, the aircraft were manufactured at Russia’s Komsomolsk-on-Amur Aviation Plant. They remain in Russia pending final delivery, with storage and related costs reportedly being covered by Iran’s Ministry of Defence.
Previously leaked Russian documents had suggested that at least 16 Su-35 fighters were under production for Iran. The latest reports indicate that the first batch of 20 aircraft is now complete.
With a combat radius of approximately 1,600 kilometres, the Su-35—designated by NATO as the “Flanker-M” or “Super Flanker”—is regarded as one of the world’s most capable fourth-generation-plus fighter aircraft. Equipped with a powerful radar, long-range weapon systems, and the ability to operate from improvised runways, it remains a formidable combat platform.
Although it is not a fifth-generation stealth fighter like the U.S. F-35 or China’s J-16, the Su-35 is considered one of the world’s most battle-tested fighter jets. Its capabilities are also being enhanced through the integration of next-generation air-to-air missiles.
Military analysts say supplying the Su-35s to Iran has become a strategic priority for Russia. As a result, deliveries of newly built Su-35s to the Russian Air Force could slow over the next few years.
Leaked documents suggest Iran ultimately plans to acquire 48 Su-35 fighter jets. The purchase is part of a broader defence agreement signed between Moscow and Tehran in 2023, which also includes Mi-28 attack helicopters and Yak-130 advanced trainer aircraft.
Iranian pilots have already begun training for the new fleet. The Yak-130 trainers delivered in 2023 are being used to prepare pilots for operating the Su-35.
According to the report, deliveries of the Su-35s could begin later this year. However, infrastructure damage at Hamadan Air Base may delay deployment, with Russian and Iranian engineers currently working to upgrade the facility.
In addition to the Su-35 order, Iran is also reportedly seeking to purchase 12 Su-30SM2 fighter jets. Discussions have also reportedly taken place regarding the possible future acquisition of Russia’s fifth-generation Su-57 stealth fighter.
Analysts believe the induction of the Su-35 will significantly enhance Iran’s ageing air force, which still relies heavily on Cold War-era aircraft such as the F-14 Tomcat, F-4 Phantom II, and F-5 Tiger.
The new fighters are expected to strengthen Tehran’s air defence and long-range strike capabilities, potentially influencing the military balance across the Middle East.
