The Philippines is actively pursuing a plan to expand and modernize its naval bases to bolster its maritime defense posture. This ambitious endeavor includes developing strategic locations near disputed waters and strengthening military cooperation with the United States.

Philippine Defense Secretary Gilberto Teodoro recently announced the accelerated construction of infrastructure on Balabac Island, the southernmost tip of Palawan province. Balabac Island, a joint air force and naval base, is considered a key area for monitoring maritime activities in the region. Secretary Teodoro stated, "This island is a strategic location for the nation," adding that the military buildup would help deter potential surveillance activities against the main island of Palawan. Philippine authorities have expressed concerns about Chinese spy cells embedded within Palawan province.

Balabac Island is approximately 140 nautical miles from Mischief Reef, a Chinese artificial island located within the Philippines' exclusive economic zone (EEZ). In 2016, the Permanent Court of Arbitration upheld the Philippines' claim over Mischief Reef, but China has rejected this decision and continues to increase its military presence in the area, which the Philippines refers to as the West Philippine Sea.

Notably, Balabac Base is one of nine Philippine military bases designated under the Enhanced Defense Cooperation Agreement (EDCA) with the United States. This agreement allows for the rotational presence of U.S. forces, pre-positioning of equipment, and U.S. funding for base modernization. EDCA-designated bases include six air force bases, two army bases, and one naval base, many of which are located in the northern Luzon region.

In addition to Balabac, the Philippine Navy is pursuing the construction of additional naval facilities nationwide. These efforts are part of a long-term "Strategic Basing Plan" aimed at enhancing maritime security and expanding naval operational reach by 2040. Rear Admiral Roy Vincent Trinidad, spokesperson for the West Philippine Sea and naval inspector, stated that this initiative is designed to support both new and existing fleets. He emphasized, "Bases are needed not only for new ships but also for older ships."

In recent years, the Philippine Navy has significantly expanded its capabilities by acquiring frigates, offshore patrol vessels, transport ships, fast attack craft, and radar and missile systems. Furthermore, additional patrol corvettes are expected to be acquired from South Korea. "We are looking for other areas where we can station our ships," said Rear Admiral Trinidad, adding, "The bigger goal is to have a stronger naval presence in those areas within the Philippines."

To this end, the Navy plans to develop 28 forward operating bases (FOBs). These smaller naval outposts will be strategically positioned near the West Philippine Sea and the Philippine Rise, northeast of Luzon. The Philippine Rise has seen an increase in Chinese research vessel activity over the past year.

Major infrastructure projects include the construction of a large naval base in Subic Bay and a support base in Mindanao, confirmed during the Navy's 127th anniversary celebration last May. President Ferdinand Marcos Jr. announced that construction of the Navasasan Naval Base would begin soon, followed by groundbreaking on Chiquita and Grande Islands in Subic Bay. These areas were formerly part of the Hanjin Heavy Industries and Construction shipyard and are located across from the Agila Subic Shipyard, which was acquired by the U.S. private equity firm Cerberus Capital Management in 2022. In March, these islands also drew public attention when several Chinese and Filipino individuals were detained by authorities on suspicion of espionage.

Meanwhile, a new naval support base for ships currently stationed at Sangley Point in Cavite will be constructed in Natividad, Misamis Oriental. Rear Admiral Trinidad stated, "For now, these areas will be declared military reservations, and later they will be developed into naval bases," adding that the government is awaiting the presidential proclamation document.

Improvements to existing facilities are also underway. Rafael Ramos Naval Base in Cebu is being prepared to accommodate the Navy's frigates and transport ships.

To increase operational efficiency and optimize resources, the military is considering joint base agreements between the Navy and Air Force. Rear Admiral Trinidad commented, "This is the direction of the Department of National Defense... Bases do not have to be exclusive. It would be better for us in terms of resource management to use bases jointly rather than developing them individually."

This naval expansion comes amidst heightened tensions in the South China Sea, where Philippine vessels continue to face harassment from Chinese maritime forces. The Philippine government views these developments as crucial steps in asserting its territorial integrity and protecting its maritime interests.
