Japan has debuted its advanced US-2 amphibious aircraft during Balikatan, the largest joint military exercises conducted between the Philippines and the United States. A ShinMaywa US-2 aircraft from the Japan Maritime Self-Defense Force (JMSDF) participated in a joint casualty evacuation drill in the South China Sea on April 27.
Joint Medical Evacuation Operations
The exercise took place near Oyster Bay in Palawan, a location serving as a staging point for Philippine military resupply missions to the Spratly Islands. This site is currently being developed with US assistance to grow a maintenance hub for patrol boats.
During the drill, the JMSDF US-2 worked in coordination with the US Navy landing dock ship USS Ashland (LSD-48). To rehearse critical medical response procedures and patient movement in realistic maritime conditions, some crew members from the US-2 were transferred to the USS Ashland via lifeboat.
Strategic Deployment and Capabilities
The US-2 is specifically designed for search-and-rescue missions, possessing the ability to take off and land on both runways and water, even in rough sea conditions.
Japan’s contribution to the exercises extended beyond the US-2. The deployment included the landing ship JS Shimokita, the destroyer JS Ikazuchi, C-130H transport aircraft, and Type 88 missiles, as well as one of Japan’s largest warships, the helicopter destroyer JS Ise.
Expanding Regional Cooperation
This iteration of Balikatan is the most expansive to date, involving approximately 17,000 troops. In addition to the US, Philippines, and Japan, key participants include the United Kingdom, France, Canada, New Zealand, and Australia.
The exercises, which run from April 20 to May 8, have featured advanced US systems including HIMARS, the Marine Air Defense Integrated System (MADIS), and the Navy Marine Expeditionary Ship Interdiction System (NMESIS), focusing on drone warfare, integrated air defense, and maritime security.
On April 28, the Japan Ground Self-Defense Force’s Amphibious Rapid Deployment Brigade and the Philippine Marine Corps conducted amphibious operations in Abulug, Cagayan. The Philippine Marine Corps stated that the exercise demonstrated seamless integration of air, land, and sea capabilities, highlighting the readiness and interoperability of the forces.
Regional Tensions and Future Outlook
These military activities occur amid heightened tensions regarding China’s activities in the South China Sea, the East China Sea, and around Taiwan. Japan and the Philippines, as US allies, are part of the First Island Chain, which is viewed as a vital line of defense for containing Chinese maritime expansion.
Looking ahead, Japan Defense Minister Shinjiro Koizumi is scheduled to visit the Philippines. He is expected to observe the sinking of a decommissioned vessel off Laoag City in Ilocos Norte on May 6, an event located near Taiwan and the South China Sea.
