US transfers three King Air 350 surveillance aircraft to Philippine Coast Guard

The United States will transfer three King Air turboprop aircraft configured for maritime domain awareness to the Philippine Coast Guard, as announced by the Pentagon on September 28, 2026. The aircraft are pre-owned, extended-range King Air 350 Maritime Domain Awareness models. This transfer is part of U.S. Efforts to strengthen Philippine intelligence-gathering amid rising tensions with China over disputed features in the South China Sea.

Contract awarded for aircraft procurement and ISR integration

Virginia-based Technology Service Corp. Received a $39.6 million firm-fixed-price contract to supply the three pre-owned King Air 350 aircraft. The U.S. Department of War announced the award, which was not competed and is funded entirely with foreign military sales money. All $39.6 million was committed at the time of award.

The contract covers procuring the aircraft, integrating intelligence, surveillance, and reconnaissance kits on two of them, and providing training. The package includes sensor operator training, ferry flights to the Philippines, technical manuals, and training materials. Delivery is scheduled by September 2028.

The Naval Air Warfare Center Aircraft Division at Patuxent River, Maryland, is managing the contract. Seventy percent of the work will take place in Crystal City, Virginia. The remaining work is spread across New Century, Meriden, and Wichita, Kansas; Manila; Concord, North Carolina; and New Smyrna Beach, Florida.

Aircraft configuration and capabilities

The King Air 350 is a twin-engine turboprop built by Textron Aviation’s Beechcraft brand, widely used for patrol and surveillance. Two of the three aircraft will be fitted with intelligence, surveillance, and reconnaissance equipment and mission management software. This software allows crews to track ships, collect imagery, and share data. The third aircraft will not carry the sensor suite.

An earlier notice stated all three aircraft would receive extended-range fuel tanks, a gross weight increase, Garmin G1000 NXi avionics, and high-frequency radios. The two surveillance aircraft will carry the King Air 350 Maritime Domain Awareness sensor package, though the specific sensors are not listed.

This transfer follows previous U.S. Support. The Pentagon has handed over several Cessna aircraft with ISR kits to the Philippine Air Force, first transferred in the 2010s for counterinsurgency and later reassigned to maritime patrol over the South China Sea. The U.S. has also supplied unmanned surface vessels and patrol boats to Philippine forces for tracking Chinese activity.

US-supplied turboprops have drawn frequent responses from the Chinese military over Scarborough Shoal. Chinese J-16 and JL-10 fighters, supported by a KJ-500 airborne early warning aircraft, recently tracked a Philippine turboprop there.

Context of the transfer and Philippine Coast Guard operations

The transfer was first agreed in February 2026. Philippine Coast Guard Commandant Adm. Ronnie Gil Gavan and U.S. Assistant Secretary of War for Indo-Pacific Security Affairs John Noh signed the letter of offer and acceptance on February 16 in Makati City. US Defense Department Undersecretary John Noh said: "The transfer was first agreed in February 2026, following a meeting between US Defense Department Undersecretary John Noh and PCG Commandant Admiral Ronnie Gavan."

At the time of signing, the Philippine Coast Guard stated the planes would strengthen its ability to watch Philippine waters and respond faster to sea emergencies. This followed the capsizing of the bulk carrier M/V Devon Bay and the January sinking of the ferry M/V Trisha Kerstin 3 off Basilan, which left dozens dead. The agency also cited the need for sustained surveillance in the West Philippine Sea, the Philippine name for parts of the South China Sea it claims. The two officials discussed a U.S. Coast Guard search planning program that uses environmental modeling to predict where people lost at sea are likely to be found.

This year, the Philippine Coast Guard became the first foreign coast guard to participate in the U.S.-led Rim of the Pacific exercise in Hawaii. The agency is expanding its role in maritime security.

Recent operations illustrate the heightened tensions. On October 1, 2026, the Philippine Coast Guard deployed its largest vessel, the BRP Teresa Magbanua, and a rigid-hull inflatable boat to challenge a Chinese research vessel off Batanes. The Chinese-flagged survey vessel JIA HAI KE 7 had been stationary about 37 nautical miles northwest of Itbayat Island since September 28. The PCG had previously accused it of spoofing its location while loitering in the area.

The BRP Teresa Magbanua came within 100 yards of the survey ship and launched a rigid-hull inflatable boat. Personnel on the boat circled the vessel several times while issuing radio challenges. The research ship repeatedly maneuvered to avoid the Philippine boats. A China Coast Guard vessel arrived and positioned itself to shield the survey ship, issuing radio challenges to the Teresa Magbanua. The PCG described the China Coast Guard’s involvement as significant because JIA HAI KE 7 is privately owned. The agency raised questions about the vessel’s ties to the Chinese government and the purpose of data gathered near undersea cable corridors off Batanes and in the Luzon Strait.

Until recently, the Philippine military focused largely on internal security. The South China Sea dispute and concerns about a Taiwan contingency spilling into the Luzon Strait are now driving Manila’s push for modern defense capabilities. Delivery of the three King Air 350 aircraft is scheduled by September 2028, with two configured for surveillance and one without the sensor suite.
