It says that the weapon system, which can easily fit into a truck, boasts a significant reduction in energy consumption for generating a strong magnetic field compared with existing technologies. According to preliminary tests, China claims it consumes only one-fifth of the energy required by current methods and can operate continuously for four hours.
The development of low-energy, compact, superconducting magnet systems is essential for large-scale production and use of microwave weapons. The report claims that the Chinese scientists involved in the project achieved the breakthrough partly due to sanctions initiated by former US president Donald Trump.
Since the US government issued an export ban on rare-earth barium copper oxide (ReBCO) and other cutting-edge superconducting materials to China in 2018, Chinese suppliers including Shanghai Superconductor Technology have faced a surge in local demand.
Asia Times noted last month that while directed-energy weapons (DEW) such as lasers and HPMs are touted as the future of counter-drone and anti-satellite weapons, HPMs are known to suffer from low efficiency, high losses in the air and limited range at atmospheric levels.
Those disadvantages have restricted the development of ground-based systems while size and power consumption hinder their use on space-based platforms.
However, recent advances in miniaturization and beam control can offset some of those disadvantages, potentially turning HPMs into practical battlefield weapons.
In March 2023, Chinese scientists from the College of Advanced Interdisciplinary Studies at the National University of Defense Technology invented a compact power source that can significantly decrease the size of HPM weapons, SCMP reported.
The report says that the device can generate electricity up to 10 gigawatts at ten pulses per second, making HPMs powerful enough to fry sensitive electronics in planes, drones and satellites.
SCMP describes the device as an electron accelerator that speeds up electrons in an unusual design sporting two spiral tubes similar to DNA. It says that the spiral tubes were submerged in glycerin, a low-cost liquid that provides excellent insulation, requires no maintenance on the battlefield and eliminates short circuits once air bubbles are removed.
As with the Stirling engine-based design, SCMP mentions that the electron accelerator is small enough to fit on a bookshelf and can be mounted on rooftops or trucks for surprise HPM attacks against overhead targets.
Compact HPM weapons may be strategically deployed on future battlefields characterized by the intensive use of drones, as seen in Ukraine and Israel.
In a May 2023 article for Military + Aerospace Electronics, Jim Romeo mentions that HPMs can destroy computers, electronics and sensors without harming human life, a capability well-suited for urban warfare scenarios that require low collateral damage.
Romeo notes that HPM weapons can neutralize enemy capabilities and combatants nonlethally, offering advantages such as deep magazine capacity, simplified logistics, negligible cost per shot, instantaneous engagement and extreme accuracy.
Along those lines, China may need such capabilities should it decide to invade Taiwan. In a January 2024 article for the Council of Foreign Relations (CFR), David Sacks mentions that if the People’s Liberation Army (PLA) were to enter Taipei, it would face costly urban warfare, having to fight street-by-street in a city of seven million inhabitants.
Furthermore, Sale Lily, in an October 2022 RAND report, describes the PLA’s approach toward urban warfare as “killing rats in a porcelain shop,” indicating the need to avoid collateral damage in trying to wrest Taiwan from urban defenders.
Woon Wei Jong, in an October 2023 Think China article, says that Taiwan’s military is preparing for urban warfare and enhancing its asymmetric warfare capabilities, including acquiring “mobile, small, portable, and AI-enabled” weapons, unmanned aerial vehicles (UAV) and counter-UAV systems.
Jong mentions that the Taiwanese military will use geography, terrain features, urban environments, buildings and critical infrastructure protection measures within tactical defensive areas for layered counter-offensive capabilities and defense-in-depth.
As such, HPM weapons may play an essential role in a potential Chinese invasion of Taiwan in terms of tackling resistance and avoiding collateral damage that could harden Taiwanese resolve to repel invading forces.
However, HPMs may not be the game-changers some are touting them to be.
Timothy Heath and other writers stress that in a 2023 RAND report, strong political leadership, a largely unified and cohesive public, and strong public support for a compelling national cause or ideology is the most durable foundation for a resolute defense.
The Rand report writers state that Taiwan’s ability to resist China in the first 90 days between an invasion and US intervention will hinge on the strength of its political leadership and social cohesion above other variables, such as military effectiveness, durability and firepower.
Absurd beyond belief.
If the Chinese attack, just shoot missiles at the three gorges dam. They’ll back down.
That’s ok, the Chicoms got Slanty Eyes and therefore WE WILL WIN!!!!
(don’t laugh, it’s pretty close to what many here think, at least based on their comments on prior stories)
Explain please.
Bkmk
Could we borrow one for the BLM crowds?
Kinetic weapon target.
How do you discriminate between friend and foe “electronics”?
“If the Chinese attack, just shoot missiles at the three gorges dam. They’ll back down.”
It seems with the usual shoddy Chinese construction the dam will fail on its own. In the very heavy rains 4 years ago or so their was a visible bulge in the dam in satellite photos.
If China invented and built this it’s junk
"Stirling engines"
Have to do more than just shoot at it.
Actually if any of the 4 major dams behind 3G goes, they figure that could do 3G in. Right now their resevoirs are very full.
Those photos unfortunately were not corrected for movement of the satellite. They were grossly incorrect. Unfortunately.
In combat that device would last a few minutes before a missile strike took it out. Even an artillery barrage would suffice.
I agree with you. When the Chinese built the three gorges dam they put a gun to their own head.
Plus shielding against microwaves is well-known. Even consumer microwave ovens employ it.
“Those photos unfortunately were not corrected for movement of the satellite. They were grossly incorrect. Unfortunately.”
Thanks for the information and that really is too bad.
Believe anything out of China at your own risk.
Well I am not saying there aren’t issues with the dam. The rumors of poor construction practices, like all their projects over there, were rampant.
