New Russian space weapon raises alarm in US
NEW DELHI: US officials have expressed grave concerns about Russia’s development of a new nuclear anti-satellite (ASAT) weapon, which could potentially transform Low-Earth Orbit (LEO) into a perilous battleground. The discussions about this emerging threat were highlighted by Mallory Stewart, the US assistant secretary of state for arms control, and John Plumb, the assistant secretary of defense for space policy, underscoring the serious implications of such developments.
The ASAT weapon in question, allegedly already tested by Russia in high radiation orbits under the guise of electronic testing, diverges from typical scientific satellite protocols. This weapon is designed to disrupt a wide array of satellite operations spanning civilian, commercial, and military sectors by detonating in LEO, which extends approximately 100 to 1200 miles above the Earth, a report in Asia Times said.
While there is no immediate deployment, the indiscriminate nature of such a weapon could severely damage satellites and impair critical global services including communication, weather forecasting, and security operations. The US officials emphasized the widespread implications of deploying such technology, noting its potential to make LEO unusable for any satellite operations.
The concept of using nuclear weapons in ASAT roles isn’t new and harks back to Cold War anxieties. Historical precedents like the US’s Project 437 during the Kennedy administration, which was later abandoned due to its potential to damage both enemy and US satellites and infrastructure indiscriminately, illustrate the complexities and risks associated with such weapons.
Recent simulations, such as those conducted by Chinese military scientists, have explored the effects of a nuclear detonation at altitude on satellite functionality. These studies show that while a high-altitude nuclear explosion would not create a traditional explosive cloud due to the absence of air, it would generate a belt of high-energy particles trapped by Earth’s magnetic field, posing a significant risk to spacecraft.
In response to the decisive role satellite constellations like Elon Musk’s Starlink have played in modern warfare, evidenced by their utility in the ongoing Ukraine conflict, both Russia and China have hinted at developing ASAT capabilities to counter these systems. Reports suggest that these nations view the neutralization of such satellite networks as crucial to diminishing their adversaries’ operational effectiveness.
US and allied commercial satellites, including those like Starlink which have been pivotal in supporting Ukraine, have been identified by Russian officials as potential targets in the event of escalating hostilities. This stance highlights the broader strategy of using space capabilities as a means of asserting dominance and the potential shift towards militarization of space, despite international treaties like the 1967 Outer Space Treaty, which seeks to bar such activities.
The development and potential deployment of nuclear ASAT weapons pose not only a technological or tactical challenge but also a diplomatic and strategic one, threatening the fabric of international space law and the peaceful use of outer space.
