Force in Play

Coordinating island defense and rapid-response exercises

On December 29-30, 2025, China executed its largest military drills around Taiwan to date, called Operation 'Justice Mission 2025,' deploying 130 aircraft, 22 warships, and live-fire exercises across seven zones encircling the island. Over two days, fighter jets crossed the median line, naval vessels simulated port blockades at Keelung and Kaohsiung, and PLA ground forces conducted coordinated long-range strikes both north and south of Taiwan. The drills escalated on December 30 with 10 hours of live-fire activities in designated 'temporary danger zones,' forcing cancellation of 76 domestic flights and delays to 300+ international flights affecting over 106,000 passengers. China framed the exercises as dual punishment: for the record $11 billion U.S. arms package announced December 17, and for Japanese Prime Minister Takaichi's warning that Tokyo could intervene militarily if Beijing blockades Taiwan.
