Chinese scientists have achieved a significant milestone in directed-energy weapon technology by successfully testing a compact high-power microwave (HPM) gun capable of firing over 10,000 shots without performance degradation. The breakthrough is attributed to a unique vacuum encapsulation system developed by researchers at the Northwest Institute of Nuclear Technology (NINT) in Xi’an. This system eliminates the need for bulky external vacuum pumps traditionally required for HPM systems. The microwave gun operates at 10-30 pulses per second, emits microwave beams exceeding hundreds of megawatts, and is powered by a three-gigawatt pulsed current. It has dimensions comparable to a conventional Gatling gun and weighs significantly less than traditional HPM systems. The weapon’s operational capabilities make it theoretically capable of attacking a variety of targets, including drones, missiles, aircraft, and potentially low-orbit satellites. China is also reportedly developing solid-state HPM weapons using GaN semiconductors, in addition to the vacuum-based system. This dual approach could provide China with advantages in the international competition for directed-energy weapon supremacy. The breakthrough in vacuum technology represents a significant advancement in making directed-energy weapons more practical for field deployment, potentially accelerating their transition from experimental systems to operational military assets.
The U.S. Navy tested its HELIOS weapon system against a threat-representative cruise missile in late 2024 with USS Preble (DDG 88). The Center for Countermeasures supported the test effort by collecting imagery. HELIOS is part of the Navy Laser Family of Systems managed by the Surface Warfare Division. The U.S. Navy is developing laser weapons to improve power efficiency and beam quality for maritime applications. The HELCAP project aims to deliver a 300+ kilowatt laser platform to defeat Anti-Ship Cruise Missiles. The U.S. Navy is also working on the Laser Weapon Testbed, incorporating technologies developed under the SSL-TM program. Further testing of HELIOS is planned on USS Preble in 2025.

Energy weapons have evolved significantly over the decades, emerging as critical components in military modernization initiatives. Research and engineering efforts during the Cold War led to advancements in high-energy lasers, microwave technologies, and electromagnetic energy. Recent breakthroughs in particle beam systems and electromagnetic weapons have enhanced military capabilities in air defense and space operations. Energy weapons operate on the principle of directed energy, utilizing technologies like lasers, microwaves, particle beams, and electromagnetic weapons for precise targeting and rapid responses to threats. Notable examples include the U.S. Navy’s Laser Weapon System (LaWS). These weapons offer benefits such as precision targeting and reduced collateral damage, but concerns about accountability and misuse persist. The future of energy weapons holds promise for transforming military operations, but ethical considerations and regulatory frameworks must be addressed.
