The drone emphasis also reflects lessons from recent conflicts. The war in Ukraine demonstrated how small commercial drones, modified with explosives, can destroy tanks and artillery worth millions of dollars. Azerbaijan's use of Turkish-made drones in the 2020 Nagorno-Karabakh war showed how unmanned systems could decisively shift battlefield outcomes against a conventionally superior opponent.

For the Philippines, the immediate operational focus is the South China Sea. Chinese coast guard and maritime militia vessels have repeatedly harassed Philippine fishing boats, blocked resupply missions to the BRP Sierra Madre—a grounded warship that serves as Manila's outpost on Second Thomas Shoal—and used water cannons against Philippine vessels.

Drones offer a way to monitor these incidents in real time, collect evidence for international legal proceedings, and potentially provide targeting data for Philippine forces if confrontations escalate. Cyber capabilities could disrupt Chinese maritime surveillance networks or complicate command-and-control during a crisis.

The challenge for Manila is sustaining the investment. The Philippine defense budget remains modest by regional standards—about $4.2 billion annually, compared to Singapore's $11 billion or Indonesia's $9.3 billion. Much of the budget goes to counterinsurgency operations against communist and Islamist groups in Mindanao and the Visayas.

The Philippine Army is also managing a generational transition in doctrine. Traditional army operations—infantry battalions securing rural areas against insurgents—differ fundamentally from the surveillance, electronic warfare, and cyber operations now being emphasized. Training soldiers for these new missions takes time and money.

Still, the doctrinal shift reflects a hard-nosed assessment of strategic reality. The Philippines has a mutual defense treaty with the United States, but Manila cannot assume Washington will automatically intervene in every South China Sea incident. Building indigenous capabilities—however asymmetric—gives Philippine decision-makers options short of dependence on external allies.

For the 110 million Filipinos, the modernization also carries economic costs. Every peso spent on drones is a peso not spent on schools, hospitals, or infrastructure. But as long as Chinese ships patrol waters Manila claims as its exclusive economic zone, the pressure to build credible deterrence will persist.

Ten countries, 700 million people, one region—and in the South China Sea, smaller militaries learning to punch above their weight.
