• Russian and Chinese naval forces have completed their first-ever joint patrol in the Asia-Pacific to include submarine operations, marking a significant escalation in military cooperation.
  • The task force, which included destroyers, an anti-submarine ship, and a supply vessel, covered over 6,000 nautical miles and conducted advanced anti-submarine warfare drills.
  • The patrol, which follows the annual Russia-China 2025 Maritime Interaction naval drill, is viewed by Western powers and regional allies as a strategic signal challenging US influence in the region.

A joint Russian-Chinese naval task force has concluded its first patrol in the Asia-Pacific to integrate submarine operations, a major step in the deepening military partnership between the two nations. The patrol, the fifth of its kind conducted annually, underscores a concerted effort to increase interoperability and project combined strength in a strategically vital region.

The flotilla, which departed from Vladivostok on August 7, included Russia’s Admiral Tributs large anti-submarine ship and China’s Shaoxing destroyer, supported by the Qiandaohu supply ship. For the first time, the joint operation included coordinated underwater activities, with a Russian Kilo-class submarine, the RFS Volkhov, participating in the initial phase of the exercise. The vessels covered more than 6,000 nautical miles, resupplying in Kamchatka, before concluding the coordinated segment of their mission.

The core of the patrol involved sophisticated anti-submarine warfare (ASW) drills. Deck-based aircraft from the ships were deployed to support detection and tracking operations in the central Pacific, showcasing a level of integrated warfare training that analysts say was previously unseen in their joint exercises. “The activities are aimed at strengthening naval cooperation between Russia and China, maintaining peace and stability in the Asia-Pacific region, and also monitoring the maritime environment,” a spokesperson involved with the operation was quoted as saying.

This development is widely interpreted by defense officials in the US, Japan, and South Korea as a direct strategic message. The inclusion of submarine patrols represents a qualitative upgrade in military cooperation that is likely to alter regional security calculations. Efforts to reach the Russian Defense Ministry for additional comment on the submarine's activities were not immediately successful.

The patrol follows the conclusion of the Russia-China 2025 Maritime Interaction naval drill, suggesting the two events are part of a continuous and escalating show of force. While officials from both Moscow and Beijing consistently frame these actions as defensive and aimed at stability, the consistent annual expansion in the complexity and scope of their exercises points to a long-term strategic alignment.

Regional security analysts monitoring the situation expect this to become a new normal. The success of this first combined submarine patrol paves the way for more complex and far-reaching joint operations in the future, potentially extending further into the Pacific and South China Sea. This increased activity is likely to prompt counterbalancing naval deployments and exercises from the US and its treaty allies in the region, contributing to an overall atmosphere of heightened military readiness.
