Russia has reportedly completed the first batch of 20 Su-35 fighter jets ordered by Iran, with deliveries potentially beginning in 2026. The reported transfer would mark Iran’s largest air force modernisation programme in decades. If completed, the acquisition is expected to significantly strengthen Tehran’s long-range air combat capabilities across the Middle East.
According to Military Watch Magazine, the aircraft were produced at Russia’s Komsomolsk-on-Amur Aviation Plant and remain in Russia pending transfer. The report said Iran’s Defence Ministry is covering maintenance and sustainment costs while preparations continue. Earlier leaked Russian defence industry documents reportedly indicated that production of the aircraft was already underway by late 2025.

The Su-35 is regarded as Russia’s most advanced operational fourth-generation-plus fighter aircraft. It is designed for both air superiority and ground attack missions, with a combat radius of nearly 1,600 kilometres. Although analysts consider its avionics less advanced than some Western fifth-generation fighters, the aircraft remains one of Russia’s most capable combat platforms and has received upgrades to its missile systems.
According to the report, Iran has already begun preparing pilots for the new fleet through deliveries of Yak-130 trainer aircraft. Engineering teams are also reportedly restoring infrastructure at Hamadan Air Base before the fighters arrive. The report further claimed Iran has ordered 48 Su-35 fighters and may later acquire additional Russian aircraft, including Su-30SM2 fighters and potentially Su-57 stealth jets.

Neither Russia nor Iran has officially confirmed the reported production milestone or delivery schedule. If the reported transfers proceed, the aircraft would represent Iran’s first major fighter acquisition since the 1990s. Defence analysts say the new fleet could substantially improve Iran’s air power after decades of relying on ageing Western and Russian aircraft.
