  • Powerful laser aboard US Navy warship destroys drones in sea trial

    The US Navy has made significant progress in deploying ship-based laser weapons, demonstrated by a 2025 sea trial where the Arleigh Burke-class destroyer USS Preble used Lockheed Martin’s High-Energy Laser with Integrated Optical Dazzler and Surveillance (HELIOS) system to successfully shoot down four drones. This marked a major advancement from earlier tests that targeted only single drones. The demonstration highlights the Navy’s focus on laser weapons as a cost-effective, sustainable defense against increasingly sophisticated drone threats, preserving expensive missile stockpiles for more advanced attacks. HELIOS, a 60-kilowatt-class laser equipped with an optical dazzler, has been operational on USS Preble since 2022, with other destroyers carrying lower-powered lasers primarily for sensor disruption. Laser weapons offer critical advantages over traditional missile and gun systems, including virtually unlimited firing capacity constrained only by power and cooling availability, and significantly lower per-shot costs compared to missiles like the $1 million RIM-116.

  • Fujian's flaws push China towards aircraft carrier with nuclear power

    China’s latest aircraft carrier, the Fujian, represents a significant advancement as the country’s first domestically designed carrier with electromagnetic catapults and the largest conventionally powered warship globally. However, emerging technical assessments reveal critical design flaws that limit its operational effectiveness. Key issues include the island superstructure’s placement near the flight deck’s center, which reduces usable deck space and creates bottlenecks during aircraft operations. Additionally, the electromagnetic catapult arrangement intrudes into the landing area and is positioned too close to an aircraft elevator, restricting simultaneous launch and recovery operations—a capability standard on U.S. supercarriers. These layout inefficiencies, combined with a narrower and shallower angled flight deck compared to American designs, likely reduce Fujian’s sortie generation rate to about 60% of that of a U.S. Nimitz-class carrier. The identified shortcomings are largely attributed to the constraints imposed by Fujian’s conventional propulsion system, which requires large exhaust funnels and machinery spaces, limiting optimal deck and

  • US Navy unleashes new mine-killing robot in first open-water test

    The US Navy, in collaboration with Raytheon Technologies, has successfully tested Barracuda, a new untethered, semi-autonomous underwater robot designed for mine neutralization. During an open-water trial in Narragansett Bay, Barracuda demonstrated its ability to navigate underwater, communicate targets, detect threats, and identify various types of naval mines—bottom, volume, and near-surface—without physical tethers or continuous operator control. While the system operates autonomously for most of its mission, human operators retain final decision authority for mine neutralization, ensuring compliance with Department of Defense rules and operational safety. Barracuda represents a significant technological advancement in naval mine warfare, offering enhanced safety and efficiency by reducing the risk to sailors. Its modular design allows deployment from multiple surface or sub-surface platforms, supporting distributed maritime operations and expeditionary mine countermeasure units. The system is slated for low-rate initial production with operational capability targeted by 2030, aligning with the US Navy’s modernization plans
