The United States has confirmed that it placed a weapon in Earth's orbit. This marks the first time the US has openly admitted that it has an offensive weapon in space. US Secretary of the Air Force Troy Meink said the weapon will help protect American forces. He said the US needs it to respond to hostile actions by enemies.
Meink spoke at the Air, Space and Cyber Conference on Monday. He said the US must prepare for "evolving threats". However, he did not explain what the weapon can do. He also did not say when the US placed it in orbit.
Growing Military Activity in Space
The US has increased its focus on military operations in space. American military leaders have also warned about the growing space programmes of Russia and China. Both countries are developing technologies that could attack or disrupt US satellites during a future conflict. Satellites play a major role in military communications, surveillance and navigation.
China responded to the US announcement on Tuesday. It warned countries against starting an arms race in space. "We urge the US side to stop expanding its military capabilities and preparing for war in outer space," AFP quoted a foreign ministry spokesman as saying.
US officials have not revealed how the new weapon works. They have also not explained what targets it can attack. A US Space Force spokesperson described the wider role of space-based military systems. The spokesperson said, "Space control encapsulates the mission areas required to contest and control the space domain – employing kinetic and non-kinetic means to affect adversary capabilities through disruption, degradation and even destruction, if necessary.
"These capabilities can be employed for offensive and defensive purposes at the direction of combatant commands."
Experts Discuss Possible Weapons
Experts also lack clear information about the new US weapon. One expert on military space technology said "precious little" was publicly known about the system. The expert told the BBC that the US announcement could refer to "a whole range of different weapons systems".
Dr Bleddyn Bowen from the Royal United Services Institute (RUSI) discussed the issue on Radio 4's Today programme. Bowen said he was "totally guessing". He suggested that the US might have deployed "some kind electronic warfare or radio jamming platform".
Such a system would use technology that already exists on Earth. It could interfere with radio signals. It could also disrupt an enemy's communications. Bowen also suggested another possibility. He said the US could have deployed "a kinetic kill vehicle of some sort - so a vehicle that would release a projectile of some sort that would ram into a satellite and destroy it".
This type of weapon could physically destroy another satellite. However, Bowen said it was less likely. A collision could create large amounts of space debris. That debris could damage other satellites. It could also create risks for spacecraft that belong to countries not involved in a conflict.
Space Weapons and the Golden Dome
The Trump administration has also highlighted the military importance of space. The administration plans to use space-based systems as part of its proposed "Golden Dome" defence system. It also plans to use interceptor missiles.
The system aims to protect the US from missiles and other airborne threats. Last year, President Donald Trump issued an executive order that expanded the stated role of the US Space Force. The order stressed that the force should defend American assets in space. It also highlighted its role as an offensive military force.
The US Space Force
The US created the Space Force in 2019. It became the first new branch of the US military in more than 70 years. The Space Force protects American assets in space. These assets include hundreds of satellites. The satellites support military communications, surveillance and navigation. They have become essential to modern military operations.
This dependence has encouraged major powers to develop systems that can protect their own satellites. They have also developed technologies that can interfere with or attack an opponent's satellites.
International Rules on Space Weapons
A 1967 international treaty prohibits countries from placing weapons of mass destruction in orbit. However, the treaty does not ban every type of weapon in space.
Since the treaty came into force, the US, Russia and China have continued to develop other military capabilities in space. Some of these systems can target or disrupt satellites. Such attacks could affect military communications, surveillance and navigation.
Russia's Satellite Activities
Russia has also faced growing attention over its activities in space. In early February, reports said that two Russian satellites had likely intercepted communications from at least a dozen European satellites.
The reported activity took place after Russia invaded Ukraine in 2022. The interceptions could have given Russian intelligence agencies access to sensitive information. In theory, such capabilities could also allow an attacker to interfere with a satellite or take control of it. In 2024, the US said Russia had launched a satellite that it believed could attack other satellites. Russia did not publicly comment on the US claim.
US Concerns About China and Russia
The US Space Force has also warned about China's growing space capabilities. The Space Force says China "develops and operates space and counterspace capabilities as part of a military modernisation strategy," while Russia "views space as a warfighting domain and believes space supremacy will be a decisive factor in future conflicts".
The latest US announcement shows how military competition has expanded into space. However, the US has not revealed the exact nature of its new orbital weapon. Officials have not disclosed its specific capabilities or deployment date. Experts have suggested several possibilities. These include electronic warfare, radio jamming and systems that could physically destroy satellites. For now, the US has confirmed the weapon's existence but has kept its technical details secret.
