Russia's ongoing military cooperation with Iran is exemplified by the active implementation of a supply contract that includes the provision of Yak-130 trainer jets and Su-35 fighter aircraft. Signed on June 10, 2021, the contract, referred to in internal documents as involving the 'foreign customer K10', has demonstrated consistent progress according to communications among various contractors responsible for the production of essential components for these aircraft. The commitment to fulfill this agreement extends through 2026, indicating a sustained partnership between the two nations.

The supply contract's execution involves several significant manufacturers, underscoring the collaborative efforts that integrate diverse technological and manufacturing capacities within Russia. Notable entities cited in the activities include Zvezda, responsible for producing critical ejection seats, and the Irkut Corporation, part of the United Aircraft Corporation, which oversees the construction and export of military jets. Moreover, the involvement of research institutes that contribute to the development of advanced materials and components, like the Institute of Polymer Materials, emphasizes the complexity and strategic importance of this military aviation program.

This partnership positions both Russia and Iran firmly within the global arms market, enhancing Iran's military capabilities and signifying a deepening of military ties amid existing geopolitical tensions. As the contract unfolds, it will likely influence regional security dynamics, particularly in light of Russia's ongoing military engagements and Iran's aspirations to boost its defensive capabilities in the face of external pressures.
