The United States has formally confirmed for the first time that it has deployed active military weapons in Earth’s orbit, raising immediate concerns over a potentially dangerous acceleration of an orbital arms race. Speaking at the Air, Space, Cyber conference, US Secretary of the Air Force Troy Meink announced that Washington now maintains operational "on-orbit" space-control capabilities. While Meink declined to elaborate on specific technologies, a US Space Force spokesperson clarified that space control encompasses both kinetic combat options and non-kinetic measures, such as signal jammers, designed for defensive and offensive operations.

for the first time= これまで一度も行われていなかったことを強調する表現。

The admission drew sharp, swift criticism from global rivals. China’s foreign ministry accused the US of "preparing for war in outer space" and warned against transforming orbit into an active battlefield. In Moscow, Kremlin spokesperson Dmitry Peskov reiterated Russia's position that space must remain completely demilitarised and entirely free of weaponry. Though the 1967 Outer Space Treaty explicitly prohibits placing weapons of mass destruction in orbit, it left open a legal loophole by failing to ban conventional orbital weapons.

left open a legal loophole= 法律や条約の不備により、規則の意図をかいくぐる余地が残されたこと。

Space security analysts caution that publicising these capabilities fundamentally shifts international norms surrounding military activity above Earth. Jonathan McDowell, an astronomer and space tracking expert formerly with the Harvard-Smithsonian Center for Astrophysics, noted that while covert space assets were long an open secret, official confirmation almost guarantees that China and Russia will deploy comparable systems in response. Experts further warn that operational escalation—or potential kinetic combat in orbit—could generate vast fields of high-speed space debris, endangering civilian satellites and long-term space infrastructure.

in response= 相手の行動に対する反応や対抗策を示す表現。

言語メモ

  • •「宇宙統制(space control)」は軍事用語であり、自国の自由な宇宙利用を確保しつつ敵対国の利用を阻止・妨害する運用能力を指します。
  • •1967年の宇宙条約は国際宇宙法の基礎ですが、大量破壊兵器の配備禁止に主眼が置かれていたため、通常兵器の軌道配備については十分に規定していませんでした。
