(Worthy News) – Iran and Russia conducted a joint naval exercise on Monday in the Caspian Sea, marking the beginning of “CASAREX 2025,” a three-day maritime security and rescue drill aimed at enhancing cooperation and coordination between the two nations’ naval forces. The drill comes just weeks after Iran’s conflict with Israel and U.S. strikes on Iranian nuclear facilities–an episode that has tested the strength of Iran’s alliances with Moscow and Beijing.
Iranian state media described the exercise as part of broader efforts to assert maritime authority in the Caspian and promote regional collaboration. The initial phase is being conducted in Iran’s “fourth maritime zone of Nadaja near Rasht,” according to the Tasnim news agency. The Russian Navy has contributed the SB738, a 57-meter frigate-class vessel, to the operation.
Despite the drill’s symbolic show of unity, underlying tensions remain. During Iran’s 12-day war with Israel earlier this year, neither Russia nor China offered tangible support to Tehran. Even after U.S. airstrikes severely damaged Iranian nuclear facilities, both powers refrained from direct intervention. Analysts view the absence of action as a stark display of pragmatism–highlighting Moscow and Beijing’s prioritization of their own strategic interests over regional solidarity with Iran.
Russia’s participation in CASAREX 2025 appears aimed at signaling continued cooperation in the wake of perceived diplomatic and military setbacks. With its resources tied up in Ukraine and its influence diminished by the fall of the Assad regime in Syria, Moscow seeks to maintain relevance in the Middle East through limited, controlled engagements like this drill.
“The main phase of this exercise will be carried out in the fourth naval zone of Imam Reza (AS) Nadaja after holding joint coordination meetings between the Iranian and Russian naval forces, as well as with the presence of observers from other countries bordering the Caspian Sea,” Tasnim reported.
The Caspian Sea holds growing strategic importance for Tehran, which has been expanding outreach to Central Asia and advocating for a new north-south economic corridor connecting the region to southern Iran and Pakistan. Maritime security in the Caspian is crucial for the success of these economic ambitions.
According to Xinhua and Mehr news agencies, the exercise includes not only the Iranian Navy and Russian Navy but also the Islamic Revolutionary Guard Corps (IRGC) Navy and Iran’s Law Enforcement Command. Observers from other Caspian littoral states are expected to monitor the operation.
Iranian Foreign Minister Abbas Araghchi recently attended the Shanghai Cooperation Organization security forum, where he met with Russian and Chinese officials and called for greater resistance to U.S. military pressure. Despite a growing list of defense pacts and shared drills, there remains no formal mutual defense clause binding the three nations.
Iran and Russia’s enhanced military coordination–though lacking full strategic depth–reflects their shared opposition to Western sanctions and interventions. Still, Tehran’s recent isolation during conflict has raised serious questions about the reliability of its would-be allies.
The U.S. State Department and the foreign ministries of Iran and Russia have not commented on the exercise as of publication.
