  • •A record 116 underwater drones were autonomously deployed in a single test.
  • •The TH-618 drones are linked to China's military advancements, particularly for the PLA.
  • •The test represents a breakthrough in underwater drone swarm technology.

On August 29, 2026, researchers from Northwestern Polytechnical University and Xi'an Tianhe Maritime Technologies achieved a Guinness World Record by deploying 116 TH-618 underwater drones in a pool, executing autonomous formations without human intervention. This event highlights advancements in underwater drone technology, which is crucial for military applications, particularly for the People's Liberation Army (PLA). The TH-618 drones, resembling long pipes with propellers, can operate autonomously for about 8 hours and navigate using AI-driven smartphone cameras. The successful test is seen as a significant milestone in developing coordinated underwater unmanned systems, which may enhance China's naval capabilities in contested regions like the South China Sea. Concerns arise regarding the potential for increased naval engagements due to the proliferation of such technologies.
