Footage released by Russia's Pacific Fleet on August 25, 2025, appears to capture a United States Navy destroyer monitoring a Russian and Chinese joint naval patrol in the central Pacific Ocean on an unspecified date in August.

Overview

  • The Russian Pacific Fleet said diesel-electric submarines from both navies conducted a coordinated patrol in early August in the Sea of Japan and the East China Sea.
  • According to the fleet, the Russian submarine Volkhov covered roughly 2,000 miles from its base in Vladivostok during the mission.
  • China has not issued an independent confirmation, with the state-run Global Times citing Russian reports and highlighting the operation as evidence of growing underwater interoperability.
  • The patrol followed the Joint Sea-2025 exercise near Vladivostok, while Chinese state television separately reported a joint maritime patrol in the western Pacific from August 6 to August 20.
  • U.S. authorities report stepped-up monitoring, including the Coast Guard tracking five Chinese research ships in U.S. Arctic waters and NORAD responding to at least four Russian surveillance flights into the Alaska ADIZ in the past week.
