美国空军部长公开确认在太空部署武器

美国空军部长特洛伊·门克本周公开确认美国已在太空部署武器12。美国军方承认轨道上存在秘密太空武器，但未透露具体功能1。这一声明被视为美国在与中国、俄罗斯的太空军事竞争中的重要里程碑1。

国际背景与政策影响

这一公开宣布被分析人士视为对中俄长期指控美国太空军事化的间接承认2。根据1967年《外太空条约》规定，在轨道或外太空放置核武器或大规模杀伤性武器被明确禁止2。中俄自2008年以来提议《防止在外太空放置武器条约》，但美国及其盟国（包括澳大利亚）拒绝参与谈判2。自1981年以来，联合国大会每年都采纳《防止外太空军备竞赛决议》，但美国自2023年起拒绝支持该决议2。

专家认为，美国的这一公开声明破坏了联合国太空军控谈判的进展，可能给中俄进行报复性太空武器开发提供了正当理由2。中国在2022年展示了能够捕获废弃卫星并将其拖动约2000公里的能力2。

The US Air Force Secretary announced this week that the United States has deployed weapons in orbit, marking a significant public acknowledgment of space militarization 12. The disclosure represents a turning point in the escalating space competition between the United States and rival powers China and Russia 1.

The weapons system, described as "on-orbit space control weapons," have been deployed to operational status, though military officials declined to reveal specific capabilities 12. This public confirmation breaks with decades of ambiguity surrounding US space weapons programs and effectively concedes what China and Russia have long accused Washington of pursuing 2.

The announcement carries significant implications for international space governance. The 1967 Outer Space Treaty prohibits the placement of nuclear weapons or weapons of mass destruction in orbit or outer space 2. However, analysts warn that the US disclosure undermines ongoing diplomatic efforts to prevent space weapons proliferation 2. China and Russia have jointly proposed a Treaty on the Prevention of the Placement of Weapons in Outer Space since 2008, a measure the US and its allies, including Australia, have refused to negotiate 2. Additionally, the United Nations General Assembly has adopted an annual Prevention of an Arms Race in Outer Space resolution since 1981, though the United States withdrew its support beginning in 2023 2.

China previously demonstrated advanced space capabilities in 2022 by showcasing technology capable of capturing defunct satellites and relocating them approximately 2,000 kilometers 2. Experts contend that the US announcement may provide Beijing and Moscow with justification to accelerate their own space weapons development programs 2.
