On Monday, Russia and Iran launched joint military exercises in the Caspian Sea under the banner “Together for a Safe and Secure Caspian Sea.” Officially, the drills aim to enhance maritime security and naval cooperation between the two countries and are being coordinated by Iran’s Northern Fleet. While such exercises might once have passed without much notice, their timing and frequency reflect a shifting dynamic: the Caspian region is rapidly emerging as a potential hotspot in global geopolitics.

Just one month prior, the same waters hosted joint military exercises between Azerbaijan and Kazakhstan, held in Aktau, western Kazakhstan. These were followed by the “Tarlan-2025” air and tactical drills in Azerbaijan from July 8-10, which focused on enhancing UAV operations and military coordination.

Baku’s strategic alliance with Ankara is a key factor here. Azerbaijan, a close Turkish partner, is now engaged in a more strained relationship with Russia. Moscow’s muted reaction to this cooling suggests an awareness that Ankara is increasingly shaping a Turkic military-political bloc, an emerging force in a region of strategic importance to both Russia and China.

Earlier this month, Turkey launched its annual Anadolu-2025 special forces exercises. Participants included troops from 33 nations, Kazakhstan, Azerbaijan, Pakistan, Uzbekistan, and others but notably excluded Russia.

For the first time, in 2024, military exercises were held in the Caspian without Russian involvement. The Birleistik (Unity) 2024 drills were conducted at Kazakhstan’s Oymasha training ground and Cape Tokmak along the Caspian coast. Troops from Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan rehearsed scenarios including conflict zone identification, night maritime operations, and amphibious landings.

Previously, regional military cooperation had been limited to bilateral engagements, such as the 2023 UZAZ exercises (Azerbaijan-Uzbekistan), Kanzhar-2023 (Kazakhstan-Uzbekistan), and Hazri-2023 (Azerbaijan-Kazakhstan).

The spike in joint drills during 2024-2025 underscores growing rivalries between regional and global powers. These operations are not mere formalities but reveal emerging security alignments and geopolitical signals.

Three distinct blocs appear to be coalescing in the Caspian, with implications for Central Asia as well.

The first bloc includes Russia, Iran, and China. These nations have held annual “Maritime Security Belt” exercises since 2019, with the most recent in March 2025 off the Iranian coast.

The second bloc comprises Turkey, Azerbaijan, and members of the Organization of Turkic States (OTS). Defense ties among these countries are becoming a core element of OTS cooperation. At the 10th OTS Summit in Astana in 2023, Azerbaijani President Ilham Aliyev emphasized defense as the main guarantor of member state security, citing ongoing regional conflicts and violations of international law.

The third bloc, more pragmatic and focused, is the Kazakhstan-Azerbaijan partnership. These countries are cooperating on the basis of the 2018 Caspian Convention to secure maritime communications. Azerbaijan contributes military expertise, particularly in UAV and drone warfare developed during the Karabakh conflicts. Kazakhstan brings diplomatic credibility and promotes regional governance and connectivity, offering a stabilizing complement to Azerbaijan’s military strengths.

In sum, the Caspian Sea, once colloquially referred to as “Russia’s lake”, is steadily losing that identity. It is transforming into a contested strategic zone, where three competing security visions intersect. The risk of escalation is real.

Whether the Caspian remains a sea of cooperation or becomes a flashpoint of geopolitical strife may soon depend on decisions made far beyond its shores.
