UPDATE: A Chinese naval vessel designed for submarine rescue operations has been spotted sailing toward Russia, raising alarms across Northeast Asia. The Dakai-class submarine rescue ship was detected in the East China Sea on July 24, 2025, coinciding with Russian naval drills that spanned the Northern Hemisphere from July 23-27.
The urgency of this situation cannot be overstated. Japan’s Joint Staff Office confirmed the sighting of the Chinese vessel, marking a significant moment as it navigated through the Tsushima Strait and into the Sea of Japan. This region is crucial, bordering Japan, the Korean Peninsula, and Russia’s Far East. The increasing presence of Chinese military assets near Japan’s waters is a stark reminder of the ongoing tensions in the region.
Japan, a key ally of the United States, forms part of the first island chain designed to contain China’s military influence. The People’s Liberation Army Navy (PLAN) has expanded its operations beyond this chain, which includes Taiwan and the Philippines, into the second island chain, comprising U.S. territories like Guam.
Analysts are closely watching this development. According to Australian naval expert Alex Luck, the Dakai-class vessels are part of China’s strategy to enhance its logistics and support capabilities for an expanding submarine fleet. “The Chinese Navy is significantly expanding their submarine salvage capability,” Luck noted. He emphasized the likelihood that the Dakai-class vessel could be deployed alongside operational submarines.
The Pentagon has flagged the modernization of the PLAN’s submarine fleet as a top priority, projecting growth from 60 to 80 vessels by 2035. This rapid expansion raises critical questions about regional security and the balance of power in the Pacific. The PLAN currently operates a mix of nuclear and diesel-powered submarines, with expectations of increased capabilities in the near future.
As tensions escalate, the Japanese military remains on high alert. It is unclear if the Chinese vessel will be detected on its return journey or if any submarines will operate near Japan’s territorial waters. This developing story highlights growing military activities in the region, prompting immediate concerns among regional allies.
Stay tuned for updates on this evolving situation as authorities and analysts assess the implications of China’s naval maneuvers. The world watches closely as these developments unfold, signaling a critical moment in Pacific security dynamics.
