A newly leaked document allegedly from Russian state defense conglomerate Rostec appears to outline detailed pricing, delivery schedules, and export plans for advanced Sukhoi fighter jets destined for several foreign clients — including Iran, Algeria, and Ethiopia.
The material was published online on October 3 by the hacker collective Black Mirror, which claims to have accessed more than 300 internal documents from Rostec’s systems.
The tranche includes correspondence, presentations, and export contracts detailing Russia’s defense cooperation with foreign partners, logistics schemes designed to evade sanctions, and technical documentation tied to arms deliveries. While the authenticity of the leak has not been independently verified, analysts say the content aligns closely with previous reports about Moscow’s export negotiations.
One of the most widely shared pages from the leak appears to list contracts from KRET, a Rostec subsidiary specializing in electronic warfare and avionics, for equipment to be integrated into export-configured Sukhoi aircraft. The document identifies the country clients by codes based on Russia’s national classification system: “364” is listed as Iran, “012” as Algeria, and “231” as Ethiopia.
According to the leaked table, Iran has ordered 48 Su-35 multirole fighters, Algeria has purchased 12 Su-57 fifth-generation fighters and 14 Su-34 strike aircraft, while Ethiopia has signed a contract for six Su-35s. If accurate, the deals would represent some of Russia’s most substantial combat aircraft exports since its invasion of Ukraine in 2022 — and signal a deepening of defense ties with several non-Western states.
The document also sheds light on delivery schedules and production timelines. Equipment for the Iranian Su-35s, for example, is scheduled to be shipped between 16–18 and 46–48 months after advance payments are received. Assuming the initial payment was made in 2022, deliveries of KRET subsystems to the aircraft manufacturing plant would occur between 2024 and 2026. Actual assembly, flight testing, and certification of the aircraft would then follow, meaning full deliveries to Iran are likely to take place between 2026 and 2028.
The leak also indicates that export components for Algeria’s Su-57 and Su-34 fleets will be supplied in the 2024–2026 period, aligning with earlier reports that Algiers was in advanced negotiations for Russia’s next-generation stealth fighter. If confirmed, Algeria would become the first foreign customer of the Su-57 — a major milestone for Russia’s troubled fifth-generation fighter program.
For Ethiopia, the document references six Su-35 fighters, suggesting that the deal may already be in advanced stages or that deliveries have begun.
The timeline outlined in the documents suggests that most of these contracts were signed or initiated prior to or shortly after Russia’s full-scale invasion of Ukraine, with delivery schedules stretching well into the second half of the decade. The complexity of the supply chain — including production of electronic warfare systems, avionics, and support equipment — also points to Russia’s need to synchronize its industrial base to meet export commitments while sustaining domestic military demand.
