U.S. nuclear command satellites want hardening towards assaults, report warns

WASHINGTON — The USA ought to harden its low Earth orbit satellites that help nuclear command and management towards radiation results from potential high-altitude nuclear detonations, in response to a new report from a outstanding suppose tank.

The Atlantic Council’s Scowcroft Middle for Technique and Safety launched a research July 15 titled “Modernizing House-Based mostly Nuclear Command, Management, and Communications” that recommends steps to guard space-based parts of the U.S. nuclear command, management and communications (NC3) system. The report comes amid rising considerations about Russia’s growth of space-based nuclear weapons and the vulnerability of crucial navy satellites.

NC3 contains the sensors, communications networks, and command facilities that enable the President to direct nuclear forces. Its house section contains satellites for missile warning, safe communications, and nuclear detonation detection.

“In a most annoying state of affairs, the efficacy of business LEO satellites in supporting Ukraine may lead the Russians (or the Chinese language in a Taiwan invasion, for example) to evaluate that the best navy effectiveness from the restricted use of nuclear weapons can be to detonate only one in LEO,” the report acknowledged.

A high-altitude nuclear blast may create widespread electromagnetic pulse results and inject high-energy particles into Earth’s radiation belts, doubtlessly crippling unprotected satellites, the authors warned. Low Earth orbit satellites between 160-2,000 km altitude are particularly in danger resulting from their proximity.

“A high-altitude nuclear detonation would elevate the height radiation flux in components of the Van Allen radiation belts by three to 4 orders of magnitude, trigger the failure in weeks to months of most if not all LEO satellites not particularly hardened towards this menace,” in response to the report.

U.S. modernizing nuclear command expertise

The U.S. is at the moment modernizing its ageing NC3 infrastructure as a part of a broader nuclear forces improve. Key house property embrace the House-Based mostly Infrared System for missile warning and the Superior Extraordinarily Excessive Frequency satellites for assured communications.

Nevertheless, a deliberate shift to smaller, distributed satellite tv for pc constellations in low Earth orbit creates new vulnerabilities that have to be addressed, the report mentioned. The House Drive’s House Improvement Company is deploying a whole bunch of satellites for missile monitoring and different navy functions.

“The flexibility of space-based NC3 techniques to make sure ‘nuclear surety’ — absolutely the reliability and safety of nuclear operations — is being challenged,” the Atlantic Council report acknowledged. “It is because these techniques could develop into weak to assault or interference from superior counterspace weapons.”

The authors suggest accelerating deployment of radiation-hardened satellites and different protecting measures for next-generation NC3 techniques.

The report highlights how the emergence of a number of nuclear friends has sophisticated the strategic panorama. It argues that China’s nuclear buildup and views on strategic stability, coupled with the opportunity of restricted nuclear use, are elevating questions concerning the adequacy of present and deliberate NC3 capabilities.

On the technical entrance, the event of subtle anti-satellite weapons by Russia and China poses a direct menace to U.S. space-based NC3 property, the research discovered. The transition from analog to digital techniques additionally introduces new cyber vulnerabilities that have to be addressed.

Because the Pentagon shifts to extra distributed satellite tv for pc architectures, the report warns that nuclear surety necessities could get missed amid competing priorities. It requires making certain these crucial capabilities stay a prime focus in future house techniques planning.
