Chinese researchers deploy GPS-denied autonomous underwater drone swarm

Bottom line

Chinese researchers have deployed a swarm of 116 TH-618 autonomous underwater drones that maintained formation without GPS using visual navigation and local algorithms. The swarm covered approximately 500 meters in 34 minutes.

Why it matters

Allied naval and coastal defense units should consider the potential for coordinated, GPS-denied underwater drone swarms to conduct reconnaissance or interference operations, necessitating enhanced acoustic and visual detection capabilities in littoral zones.

Chinese researchers have demonstrated a swarm of 116 TH-618 autonomous underwater drones operating in a GPS-denied environment. The drones maintained formation and coordinated movement using visual navigation and local algorithms, covering approximately 500 meters in 34 minutes. This capability highlights advancements in decentralized autonomous systems for underwater operations, reducing reliance on satellite navigation which is vulnerable to jamming or spoofing.
