U.S. Donates $13 Million in Autonomous Sea Drones to Strengthen Philippine Maritime Defense

On 22 June 2026, the United States handed four Ocean Aero Triton autonomous underwater and surface vehicles (AUSVs) to the Philippine Navy at Subic Naval Operating Base. Valued at $13 million (PHP754 million), the drones can operate for up to 30 days, expanding Manila’s capacity to monitor its maritime domain.

The handover comes amid heightened South China Sea tensions. Beijing’s floating platform on Scarborough Shoal was removed after Manila’s protest, though China called it a scientific-survey device. China still claims most of the sea despite a 2016 arbitral ruling, which the Chinese embassy called “only undermined bilateral ties and regional peace and stability,” the Philippine foreign ministry rejects.

U.S. Embassy Chargé d’Affaires Bridgette Walker, Senior Defense Official Col. Daniel Oh, Philippine Fleet Commander Rear Admiral Joe Anthony Cabahug-Orbe, and Lt. Cmdr. Aldwin Pasicolan of the Navy’s unmanned vessel unit attended the ceremony.

The Triton AUSVs operate above and below water, transmit data via a resilient network, and run on solar power for up to 30 days. The four-unit set costs $13 million (PHP754 million).

The U.S. Embassy said the donation shows Washington’s commitment and will improve Manila’s detection of illegal fishing, gray-zone activity, and navigation threats. Walker stressed that maritime security requires persistent, long-endurance awareness beyond the reach of single ships or aircraft. Col. Oh described the delivery as proof of an enduring alliance-modernization commitment and said next phase will integrate the drones into Philippine defense concepts.

China’s embassy portrayed the 2016 arbitral ruling as harmful to regional stability and implicitly questioned external assistance to Manila’s maritime posture.
