US has deployed weapon in space: Why it could change modern warfare
The United States has, for the first time, publicly acknowledged that it has deployed a weapon in space, a disclosure that could signal a major shift in how future wars are fought, and turn Earth's increasingly crowded space environment into an active battlefield.
US Secretary of the Air Force Troy Meink confirmed the existence of an “on orbit” weapon while speaking at the Air, Space and Cyber Conference on Monday.
He said the capability was necessary to protect US forces against hostile action and to respond to “evolving threats”. However, he did not disclose what the weapon does, when it was launched or how it would be used.

GPS navigation, secure communications, missile warning systems, battlefield surveillance and intelligence gathering all depend heavily on spacecraft orbiting Earth.
Destroy or disable those satellites, and an adversary could potentially blind, disrupt or slow an entire military operation.
This is why the US, China and Russia have increasingly invested in so-called counterspace capabilities, technologies designed to interfere with or attack another country's space assets.
The US Space Force, established in 2019, has already moved beyond describing its mission solely as protecting American satellites. A spokesperson said “space control” includes the use of kinetic and non-kinetic capabilities to disrupt, degrade and, if necessary, destroy an adversary's space systems.
The 1967 Outer Space Treaty bans weapons of mass destruction in orbit, but does not prohibit all conventional weapons or military systems in space. That leaves room for countries to develop systems capable of targeting satellites without technically violating the treaty's central prohibition.
The latest disclosure comes as Washington increasingly points to Russian and Chinese space programmes as potential threats.
The US has previously accused Russia of deploying a satellite potentially capable of attacking other spacecraft, while American officials have warned that China is developing counterspace capabilities as part of its military modernisation.
The emergence of offensive space weapons could fundamentally alter warfare because the first battle in a major conflict may no longer begin on land, sea or in the air.
It could begin hundreds or thousands of kilometres above Earth, with nations attempting to knock out the satellites that make modern warfare possible.
For militaries, space is becoming not just a place to operate, but a domain that must be controlled.- EndsPublished By: Sibu Kumar TripathiPublished On: Sep 15, 2026 13:18 IST
