A New Arms Race is Threatening to Take-off—this time in Outer Space

By Thalif Deen

UNITED NATIONS, Sep 24 2026 (IPS) – The world’s ongoing arms race is threatening to extend beyond planet earth—and spillover into outer space.

The US has deployed weapons in space and will use them to defend American forces, Air Force Secretary Troy Meink said last week, according to Cable News Network (CNN). His comments marked the first public acknowledgment of such capabilities, though he offered no details about the weapons or when they were put into orbit.

“Today we continue to ensure we remain ready to meet the challenges of evolving threats wherever they exist,” Meink told the Air, Space and Cyber Conference, an annual gathering hosted by the Air & Space Forces Association in National Harbor, Maryland.

The disclosure comes as the US faces an advancing space arms race with China and Russia, which are testing sophisticated offensive capabilities.

Specifically, American officials have said they are monitoring China’s development of a nuclear-capable partial-orbit hypersonic missile. US intelligence has also suggested Russia is developing a space-based nuclear weapon that could knock out satellites critical to weather forecasting, navigation, banking, shipping and emergency services — a claim Moscow denies, according to CNN.

The New York Times quoted Guo Jiakun, a spokesman for China’s Foreign Ministry as saying: ‘We urge the US side to stop expanding its military force and preparing for war in outer space”.

There have also been reports that “Russia could be planning to put a nuclear weapon in space, a threat that could disrupt satellite networks that are vital to everything – from communications to military operations.”

The multiple UN Conferences on the Exploration and Peaceful Uses of Outer Space (UNISPACE), have served as landmark global summits to shape international cooperation and policy for space exploration.

Convened at the Hofburg Palace in Vienna from 14 to 27 August 1968, UNISPACE 1 focused on the practical benefits of space technology and scientific exchange

Tariq Rauf, former Head of Verification and Security Policy, at the Vienna-based International Atomic Energy Agency (IAEA), told Inter Press Service (IPS) , while appreciating the transparency shown by the US, this disclosure is the most consequential open acknowledgement by any spacefaring State of weaponised on-orbit capability since the erosion of the informal post-Cold War taboo on space weapons.

The testing began with the 2007 Chinese ASAT test and the 2008 and 2021 Russian ASAT tests., the 2008 US and 2021 Russian ASAT tests, and India’s 2019 Mission Shakti ASAT test — building on earlier direct-ascent ASAT programs pursued by the United States and the Soviet Union from the 1960s through the 1980s.

The US deployment converts a long-suspected capability gap into a declared fact, and it will be read by other delegations as confirmation that at least one major power has moved decisively from space “control” doctrine to operational deployment, he said.

For the UN Committee on the Peaceful Uses of Outer Space (COPUOS) and the Ad Hoc Committee of the Conference on Disarmament on Prevention of an Arms Race in Outer Space (PAROS), the announcement raises four immediate questions:

(1) whether the deployment is compatible with the existing Outer Space Treaty regime; (2) what it means for the stalled draft Treaty on the Prevention of the Placement of Weapons in Outer Space, the Threat or Use of Force against Outer Space Objects (PPWT) and the EU Code of Conduct (EU International Code of Conduct for Outer Space Activities); (3) how the expert and policy community is interpreting the move; and (4) what practical steps the Committees can recommend to prevent a cascading arms race in space.

Rauf proposed five recommendations:

1. Convene an urgent joint briefing between COPUOS’s Scientific and Technical and Legal Subcommittees and the CD’s PAROS Ad Hoc Committee to develop a shared factual record of the announcement and its technical implications, avoiding duplicated or contradictory assessments across the two bodies.

2. Both PAROS Ad Hoc Committee and COPUOS should issue an urgent call for a moratorium on placing weapons in Space, urge the US to take down space weapons it has deployed and urge all spacefaring States to preserve Space as the common heritage of humankind and weapons-free.

3. Request, through the Conference on Disarmament Secretariat, that all spacefaring States with counterspace capability — not only the United States — provide voluntary technical briefings on the general character (though not classified specifics) of any on-orbit weapons systems, to reduce the information asymmetry currently driving worst-case assumptions.

4. Task the Legal Subcommittee with producing a technical working paper clarifying the scope of Article IV of the Outer Space Treaty as applied to conventional (non-WMD) on-orbit weapons, and the interaction of Articles III and IX with counterspace operations, to give delegations a common legal baseline rather than competing unilateral interpretations.

5. Encourage major space powers to reaffirm, at head-of-delegation level, existing voluntary moratoria on destructive kinetic ASAT testing, and invite additional States to associate themselves with such moratoria pending progress on a binding instrument.”

Jonathan Granoff, President Global Security Institute, told IPS placing offensive weapons in space is a very risky proposition.

The Outer Space Treaty has been instrumental in ensuring numerous benefits of outer space, including satellites and exploration. All major nations are parties including United States, Russia, China, India, Japan, and all member states of the European Space Agency. The Treaty in its first article establishes that space exploration and use shall only be for the benefit and in the interests of all countries and shall be the province of all mankind, ensuring free and non-discriminatory access for all states.

The deployment of weapons in space by the United States could easily be interpreted as violating that peaceful uses principle, he pointed out.

“However, there is an argument that putting weapons in space for defensive purposes only helps protect against abuses of the peace which is in the interest of all nations. This is not frivolous. The problem with that argument is that weapons used for defensive purposes can also be used offensively and the deployment of such weapons would indeed violate the the Treaty. Moreover, such a deployment by one nation will surely stimulate an arms race.”

There are several important questions, he said.

Should the entire world trust that the weapons the US places in space would only be used defensively to preserve the peace? If the US places weapons in space would this new interpretation of the Treaty stimulate other nations to do the same? Would it be wise to trust they would only use their weapons defensively?

Recall that President Reagan, addressing such questions, offered to share his Star Wars deployments of space based missile defenses with the Soviet Union. Would it be a good idea for the US to share space weapons technologies with other nations?

“The entire world benefits very much from the current military uses of outer space which allows the observation of the military activities of all nations thus helping stability. Such uses should affirmatively be protected and encouraged. Other uses that will lead to a new arms race should be prohibited. A protocol to the OST to prohibit offensive weapons in space as well as any anti-satellite weapons should be obtained”, declared Granoff..
