Solar-Powered Autonomous Maritime Vehicles Transferred to Philippine Navy

U.S. Embassy Philippines has confirmed the transfer of four solar-powered autonomous underwater and surface vehicles from the United States government to the Armed Forces of the Philippines, supporting enhanced maritime surveillance and awareness capabilities.

Valued at approximately Php754 million ($13 million), the delivery of the Ocean Aero Triton Autonomous Underwater and Surface Vehicles (AUSVs) demonstrates a commitment to the U.S.-Philippines Alliance and to a free and open Indo-Pacific. The turnover ceremony, held at the Philippine Navy’s Naval Operating Base Subic, was led by U.S. Embassy Chargé d’Affaires, a.i., Bridgette Walker, U.S. Embassy Senior Defense Official and Chief of the Joint U.S. Military Assistance Group-Philippines Colonel Daniel Oh, Philippine Fleet Commander Rear Admiral Joe Anthony Cabahug-Orbe, and Philippine Navy Unmanned Surface Vessel Unit Acting Commander Lt. Cmdr. Aldwin Pasicolan.

The Triton AUSVs are capable of collecting data both above and below the ocean’s surface through a resilient mesh network. Because the units are solar-powered, each vehicle can operate for up to 30 days, providing persistent, long-endurance awareness to improve decision-making at the tactical and operational levels.

Chargé d’Affaires Walker said in her remarks, “The four Ocean Aero Triton AUSVs we are transferring today represent something important: the future of maritime security is not just about platforms—it is about capability, speed, and reach. The Indo-Pacific’s maritime domain is vast, contested, and critical, and the Philippines sits at the heart of it. The ability to monitor and respond to maritime challenges—illegal fishing, gray zone activities, and threats to freedom of navigation—requires persistent, long-endurance awareness that no single ship or aircraft can provide alone. The Triton fills that gap by expanding the capabilities of the Philippine Navy into critical waterways.”

The delivery highlights how aligned investments, training, and shared standards translate into credible, ready capabilities that deter aggression and support regional stability.

Colonel Oh, added, “Today’s delivery highlights our enduring commitment to stand with the Philippines and invest in Alliance modernization in a manner that supports the bilateral Philippines-U.S. Security Sector Assistance Roadmap objectives. These unmanned capabilities support the AFP’s transition to territorial defense and improve awareness in critical waterways. The next step is to assist the Philippines integrate these new capabilities in their employment and sustainment concepts.”
