**Washington confirms it has placed weapons in orbit – but the details remain murky**
For the first time since the launch of the first artificial satellite in 1957, a senior U.S. defense official publicly acknowledged that the United States has “on‑orbit” weapons. In a briefing on 12 September, Air Force Secretary Frank Kendall said the U.S. “has weapons in space” and that they are “ready to be used if needed.” The admission follows years of speculation spurred by a series of classified programs under the Space Development Agency (SDA) and the U.S. Space Force’s “proliferated low‑Earth‑orbit” (LEO) architecture, which aim to protect U.S. satellites from hostile threats. While the Pentagon has not released technical specifications, officials have hinted that the payloads could include kinetic interceptors capable of striking hostile objects and directed‑energy modules designed to disable adversary sensors or communications.
Defense‑industry reports and statements to the media suggest that the new orbital weapons are part of a broader “missile‑defeat” strategy. The SDA’s “Proliferated Warfighter Satellite Constellation” (PWSC) is slated to field dozens of small, maneuverable satellites equipped with either “hard‑kill” kinetic kill vehicles (K‑KVs) or high‑power lasers that can neutralise enemy missiles or anti‑satellite (ASAT) weapons before they reach critical U.S. assets. According to *Defense One*, the program is already field‑testing “on‑orbit interceptors” that can track and physically collide with target debris or hostile projectiles. The Department of Defense has emphasized that these capabilities are defensive, meant to preserve the functionality of the nation’s space‑based communications, navigation and intelligence networks, which have become integral to modern military operations.
The revelation has drawn swift criticism from Beijing, which warned the United States to “stop preparing for war in outer space.” In an official statement, China’s Ministry of Foreign Affairs said the deployment of space weapons “undermines global strategic stability” and threatens the peaceful use of outer space—a principle enshrined in the 1967 Outer Space Treaty. Analysts in *The Guardian* and *The Hindu* warn that the U.S. move could trigger a new arms race, prompting other space‑faring nations to accelerate their own offensive programs. The United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) is expected to convene an emergency session to discuss possible regulatory responses, as the international community grapples with how to balance national security imperatives against the risk of weaponizing a domain that has hitherto been largely cooperative.
