Are commercial sea drones a new headache for PLA in South China Sea and Taiwan Strait?

The latest encounter reportedly took place 105km (65 miles) northwest of Luzon, the largest Philippine island, but the exact location was not disclosed.

The company did not respond to questions about who commissioned the drone involved in last month’s incident or what mission it was carrying out, but the firm has said previously that it had received more than US$100 million in US government contracts.

“The key point isn’t that a Chinese destroyer was observed; it’s that a relatively inexpensive commercial platform was able to do it,” said Ray Powell, director of Stanford University’s SeaLight Foundation.

So far, the Philippines has not reacted to the latest incident, while the Chinese foreign ministry has said only that the People’s Liberation Army Navy’s activities complied with international law.
