Japan’s Ground-Based Air Defense Options to the Philippines

Bilateral defense relations between Japan and the Philippines come at an all-time high, signifying the continuous cooperation between both maritime nations that share a common adversary and similar situation regarding territorial domains and integrity in the Indo-Pacific region.

With the success of the export of the aforementioned radar systems to the Philippines from Japan, the latter is now raising up an idea of the likelihood of selling its surface-to-air missile batteries for the Philippine military to consider, with a wide variety of variants coming from the Japan Ground Self-Defense Force that might find its way for the likes of the Philippine Air Force. This is especially in line with the recently passed New Government Procurement Act or NGPA (Republic Act 12009), allowing the purchase of second-hand military hardware, provided it is economically preferable to the government.

What the article left out is; to shoot far, the Philippine military needs to see far. However, the Philippines don’t have any over-the-horizon (OTH) radar, military satellites, AWACS planes or other long-range ISR capabilities, to make use of the full range of the BrahMos missile. Without it the missile is limited to the range of its available ISR assets, which are measured in just dozens of kilometers.

However, if a BrahMos missile is ever launched against a long-range Chinese target, it will be easy to guess who would have supplied the essential Intelligence, Surveillance, and Reconnaissance (ISR) information and target identification to the Philippine military.

South China Sea: Philippines’ anti-ship missile base puts Scarborough Shoal in cross hairs

Even if the Philippines lacks the advanced communications, intelligence, and targeting systems needed to maximise the BrahMos’ capabilities, it could still leverage US support in these areas, Koh said, citing the sinking of Russia’s Moskva warship by Ukraine in 2022, which he said was achieved thanks to “targeting support provided by Kyiv’s allies, chiefly the Americans”.

The flagship of Russia’s Black Sea Fleet, the Moskva became the largest warship lost in combat since the second world war when it was hit by two Ukrainian Neptune anti-ship missiles in April 2022. US officials later told the media that the Pentagon had provided intelligence that led to the ship’s sinking.

For the Philippines, the BrahMos missiles are “significant game changers” [🙄], according to security strategist Chester Cabalza, president of the International Development and Security Cooperation think tank in Manila.

However, Don McLain Gill, an international-studies lecturer at De La Salle University in the Philippines, questioned whether the BrahMos purchase alone would deliver robust deterrence against China.

“It will be crucial for the BrahMos to be supplemented by efficient intelligence, surveillance, target-acquisition and reconnaissance, which is critical to track targets and ensure they can be used by command,” he said, warning Manila must invest further to maximise the missiles’ deterrent value.
