The findings come as tensions in the Middle East remain high and ongoing conflicts reshape alliances.
Long-term deals
According to WPTech, citing United24 Media, leaked materials indicate that Russia plans to supply weapons for Su-35 fighter jets to Iran through at least 2027.
The documents reportedly outline agreements not only for the aircraft themselves but also for their full combat systems, including missiles and related components.
United24 Media reports that the arrangements stem from a contract dated June 10, 2021, in which the foreign client is identified as “K10,” believed to refer to Iran.
Missile systems
The documents list several types of weapons linked to the deal.

These include Kh-38 air-to-surface missiles, K-73 and K-77 air-to-air missiles, as well as Kh-31 systems, which can also be used in anti-ship roles.
According to WPTech, analysts say such equipment could play a significant role in ongoing conflicts in the region.
Production pipeline
The leaked materials also detail production orders across multiple Russian defense facilities.
United24 Media reports that between 2023 and 2024, components tied to the Kh-38 missile were scheduled for manufacturing, while additional contracts covered warheads for K-73 missiles and engine parts for K-77 systems.
Further orders involve plants in Perm and St. Petersburg, with deliveries for some components expected to continue through 2027.

Timing concerns
The documents also reference a contract for 164 propellant charges intended for Tehran, with production planned to begin in late 2025.
According to United24 Media, the timeline suggests that deliveries could coincide with ongoing hostilities, as Israel and the United States have reportedly been conducting strikes against Iran since February 2026.
Analysts cited by the outlet say this raises the possibility that weapons linked to the Su-35 program could reach Iran during active conflict conditions.
