The US has confirmed it has placed a space weapon in Earth orbit, the first time it has admitted such offensive capabilities.
US Air Force Secretary Troy Meink said the "in-orbit" weapon was necessary to protect US forces from hostile enemy actions.
Speaking at the Air, Space and Cyber Conference on Monday, Meink said the US was ready for "evolving threats" but did not provide details on the weapon's capabilities or when it was put into orbit.
Senior military leaders have previously said they plan to increase military capabilities in space, citing Russian and Chinese programs that are developing ways to attack and disrupt American satellites in a future conflict.
The Trump administration has said that space capabilities - and interceptor missiles - are an essential part of its planned "Golden Dome" defensive system to protect the US from missiles and other aerial threats.
A 1967 treaty banned weapons of mass destruction in orbit. Since then, major powers, including the US, Russia and China, have explored other capabilities outside the treaty, such as targeting rivals' satellites - which are essential for communications, surveillance and military navigation.
Last year, President Donald Trump issued an executive order outlining the role of the US Space Force not only in asset protection but also as an offensive force.
The US Space Force - the newest branch of the US military in more than 70 years - was launched in 2019 as a way to protect American assets in space, including hundreds of satellites used for communications and surveillance.
A US Space Force spokesperson said: “Space control encompasses the mission areas necessary to counter and control the space domain – using kinetic and non-kinetic means to affect an adversary’s capabilities through disruption, degradation and even destruction, if necessary.”
"These capabilities can be used for offensive and defensive purposes in the direction of combat commands."
In early February, it was revealed that two Russian satellites have likely been intercepting the communications of at least a dozen European satellites since Russia's invasion of Ukraine in 2022.
Such intercepts could have allowed Russian intelligence services to read the sensitive data they transmit, or hypothetically, even take control of the satellites.
In 2024, the US said Russia had launched a satellite it believed could be capable of attacking other such probes. Russia has not commented publicly on the matter.
The US Space Force says China "develops and operates space and counter-space capabilities as part of a military modernization strategy", while Russia "views space as a battlefield and believes that space supremacy will be a decisive factor in future conflicts"./ BBC.
