US Transfers Two T38 Devil Ray USVs to Philippine Marine Corps at Subic Bay

Two Maritime Tactical Systems T38 Devil Ray unmanned surface vessels were transferred to the Philippine Marine Corps at Subic Bay on November 4, expanding Washington's drone delivery program beyond the Philippine Navy. MARTAC simultaneously opened a drone center of excellence at Subic Bay to train Philippine operators and supply parts.

If the Philippine Army receives USVs through the same program, MARTAC's Subic Bay facility becomes the logistics hub for three separate Philippine service branches, which gives the Florida-based firm a durable foothold in Southeast Asian drone sustainment that Ocean Aero — which delivered four Triton drones to the Philippine Navy over the summer — does not yet match.

The BrahMos coastal missile batteries already repositioned along the Luzon Strait sealines give the Marines a strike layer; USV-enabled domain awareness fills the sensor gap that previously forced those batteries to rely on less persistent surveillance assets.

WHY IT MATTERS

Philippine Marines man the outposts at the center of South China Sea confrontations with Chinese regular and paramilitary forces, so adding USVs to their inventory extends maritime domain awareness directly into the contested zone rather than keeping it at the naval-service level.

The MARTAC facility at Subic Bay is the more durable element: a local parts depot and training center means the Philippine Marine Corps can sustain and expand the fleet without depending on US logistics each time, and the company release explicitly targets a large USV fleet over the next several years.

A Pentagon decision to extend the program to the Philippine Army — flagged by an unnamed US defense official — would be the next observable step.

WHAT THIS DOESN’T TELL US

What is the operational status of the Philippine Navy's existing USV Unit One — specifically, how many of the T38 Devil Ray and four MANTIS T12s are mission-capable, and has the Navy integrated them into any live South China Sea patrol rotation?
