Updated (5 articles)
US F‑16s Fly Near Chinese ADIZ Triggering Brief Standoff On 20 February 2026, U.S. Forces Korea (USFK) launched several F‑16 fighters from Osan Air Base into international waters of the Yellow Sea, positioning between South Korea’s and China’s air‑defence identification zones. Chinese fighter jets scrambled to the area, creating a brief aerial encounter that ended without any hostile engagement. USFK had warned the South Korean defense ministry of the flight but did not disclose the exercise’s purpose or detailed flight paths [4][5].
South Korean Defense Leaders File Formal Protests Defense Minister Ahn Gyu‑back lodged a formal protest with USFK commander Gen. Xavier Brunson by telephone on 21 February 2026, immediately after receiving the incident report. Joint Chiefs chairman Gen. Jin young‑sung also submitted a protest in a separate call, underscoring Seoul’s displeasure with the lack of coordination. Both officials demanded clearer communication and prior consent for future operations [3].
US Commander Issues Apology and Cuts Drill Early On 24 February 2026, Gen. Brunson personally apologized to South Korean military authorities for the “lack of advance notice” surrounding the Yellow Sea exercise. Following the apology, USFK terminated the drill two days earlier than the scheduled Saturday conclusion, ending the operation on Thursday. USFK declined to comment on any senior‑level talks that may have taken place [1].
Seoul Received Only General Notification, Not Detailed Consent Washington informed Seoul that the drills would occur but omitted specifics such as scope, objectives, or proximity to sensitive airspace, prompting concerns over respect for Korean sovereignty. An editorial highlighted the risk that South Korea could become a launchpad or target in a great‑power confrontation without transparent disclosure. The piece called for public sharing of flight paths, rules of engagement, and explicit Seoul approval for future operations [2].
USFK Emphasizes Flexibility and Ally‑Led Deterrence Strategy Gen. Brunson promoted a “flexibility” doctrine, presenting a “bubble perimeter” map that shows forces already positioned inside a potential crisis zone. The exercise aligns with the U.S. National Defense Strategy’s shift toward ally‑led deterrence against China, urging partners like South Korea to assume greater responsibility for regional security. USFK offered no comment on the specific incident, maintaining a broader strategic narrative [4][5].
