一批原定由澳洲运往美国进行检验与维修的敏感F-35战机零件，包括涂有雷达吸波材料的驾驶舱座舱罩与武器舱门，在透过UPS运送途中经南韩转机时意外被转运至香港，随后遭到中国政府扣留且至今尚未归还。

事件曝光时机正值中国国家主席习近平访美与美国总统川普会晤之际，引发美国政界强烈震撼与安全疑虑，多位国会议员警告敏感隐形技术恐遭外泄，目前美国众议院及参议院多个委员会已对此展开调查。

五角大厦、澳洲国防部与洛克希德马丁公司正积极协调以索回相关组件，并深入调查运输失误原因以强化防范措施，同时UPS也已向美国国务院国防贸易管制局进行主动通报。

Sensitive F-35 stealth fighter parts, including a cockpit canopy and weapons-bay door coated with radar-absorbing material, were inexplicably diverted to Hong Kong after stopping in South Korea during a UPS shipment from Australia to the US, and have since been seized and retained by the Chinese government.

The incident surfaced at a highly delicate diplomatic moment as Chinese President Xi Jinping arrived for a state visit in the US, prompting intense scrutiny from US lawmakers and triggering investigations across multiple congressional committees over potential intelligence and military risks.

The Pentagon, the Australian Department of Defence, and Lockheed Martin are actively cooperating to retrieve the components and review shipping protocols to avoid future recurrences, while UPS has notified the US State Department's export control authorities.
