‘Dust walls’ could defeat hypersonic weapons – think tank — Analysis
A contemporary model of the nuclear ‘mud protection’ may very well be key to countering the menace, a Raytheon and Lockheed-backed paper says
The US may defend itself in opposition to enemy hypersonic gliders by dispersing clouds of mud over massive areas by which such projectiles are anticipated to fly, a brand new white paper has recommended. Touring by such an space at excessive pace would degrade and doubtlessly destroy the weapon.
The concept was mentioned in a doc printed this week by the Heart for Strategic & Worldwide Research (CSIS), a Washington-based think-tank. The authors careworn that it “was made doable by assist from Raytheon Applied sciences and Lockheed Martin,” American protection giants creating anti-missile applied sciences for the US navy.
The concept just isn’t in contrast to what US strategic planners got here up with through the peak of the Chilly Battle with the Soviet Union. The proposal on the time was to position nuclear fees across the areas the place US intercontinental ballistic missile silos had been positioned. In case of an change, the bombs would blow up minutes earlier than the Soviet nukes would hit. With a whole bunch of hundreds of tons of radioactive mud within the air, enemy reentry autos arriving at excessive pace would get broken by the particles, saving the American missiles for a retaliatory strike.

The fashionable-day incarnation would use the identical idea of subjecting a rapid-flying weapon to a cloud of mud it was not designed to resist.
“Absent heavy mitigation measures, disruption of the hypersonic flowfield may result in progressive deterioration of efficiency or a mission kill, if not outright catastrophic failure,” the report predicted.
The particles can be engineered to stay suspended within the skinny higher layer of environment, by which hypersonic gliders journey, for tens of minutes, requiring much less accuracy within the timing of the countermeasure. The factitious mud may very well be metallic, pyrotechnic, or product of different materials, and deployed by a missile or an airborne platform.
“Given the upper speeds earlier within the flight of a hypersonic glider, a ‘wall of mud’ can be simpler earlier slightly than later in its flight,” the report recommended.
The white paper explored different concepts of how one can sort out hypersonic weapons, not solely gliders but in addition cruise missiles. They ranged from deploying anti-missile belongings in a method that may pressure adversaries to plot much less favorable assault paths, to utilizing highly effective microwaves to fry the missile’s digital elements, to attempting to destroy them with laser weapons.
Hypersonic weapons are thought-about a recreation changer within the strategic stability of energy, as a result of the pace at which they journey and their skill to maneuver unpredictably mid-flight makes them way more tough to intercept by conventional means than older ICBMs, which fly in predictable trajectories.
Russia fields what it claims to be a practical hypersonic glider referred to as Avangard as a part of its nuclear deterrence pressure. China can also be understood to have extremely superior prototypes of this type of weaponry.
The US has been investing closely in its nationwide anti-ballistic missile system since 2002, when it withdrew from a treaty that it had signed with the USSR that prevented each nations from creating related applied sciences.
Moscow has mentioned it needed to develop hypersonic functionality to rebalance the degradation of its nuclear deterrence attributable to rising US anti-missile capabilities.
