Philippine and US forces showcased the NMESIS anti-ship missile system in Batanes province, near Taiwan, during annual Balikatan exercises, highlighting the Luzon Strait's strategic role in Asia-Pacific tensions, reports Reuters.

The NMESIS, capable of targeting vessels at ranges of 185 km, was flown into Basco on a US C-130 transport aircraft. The missile is designed for remote operation and full autonomy, allowing training in environments not normally available.

Philippine exercise director Francisco Lorenzo stated that the deployment was a rehearsal to test feasibility in remote locations. The system will not be used in live operations and will be withdrawn after the drills. The US previously deployed its Typhon missile system to the Philippines in 2024.

Security analyst Chester Cabalza noted that the NMESIS deployment in Batanes could be perceived by Beijing as part of a US-led encirclement of China, adding that it provides asymmetric deterrence for Manila and Taipei in the Bashi Channel. The system can be airlifted and deployed to any Philippine coastline within hours.

More than 17,000 troops, including 10,000 from the US, are participating in this year's war games. Exercises include maritime strike drills in Itbayat, the northernmost Philippine municipality, about 155 km from Taiwan. China has recently increased naval activity around Taiwan and erected a barrier at Scarborough Shoal.

Philippine President Ferdinand Marcos Jr. has warned that Filipinos in Taiwan would need evacuation if war breaks out, potentially dragging the Philippines into conflict. Defence Secretary Gilberto Teodoro confirmed that contingency plans exist but provided no details.
