Philippine waters see five Chinese-linked underwater drones

The National Security Council (NSC) expressed alarm over five underwater drones found in Philippine waters between 2022 and 2024, confirming that at least three are conclusively of Chinese origin.

Rear Admiral Roy Vincent Trinidad stated on Tuesday, April 15, that the likelihood of these drones being deployed by China ranges from 55 to 80 percent based on their components, which include water depth, temperature, salinity, and underwater sound detection data.

Forensic analysis revealed that three out of the five drones contain Chinese-made iridium transceivers and China Telecom SIM cards, while two others have sanitized or defaced markings to prevent reverse engineering.

The devices were discovered at strategic locations including Pasuquin, Ilocos Norte; Calayan Island; Initao, Misamis Oriental; Zambales; and San Pascual, Masbate, capable of receiving, processing, storing, and transmitting data via satellite communication for potential maritime surveillance and underwater mapping.

National Maritime Council Spokesperson Usec. Alexander Lopez stated that the drones can be used for both military and non-military purposes, while Assistant Director General Jonathan Malaya urged increased maritime patrols to prevent such activities.
