Engineers have long looked to origami and kirigami for inspiration when designing lightweight structures that can transform shape without relying on complex mechanical systems....

As defense technology becomes increasingly software-driven, military organizations are looking beyond traditional defense contractors and toward companies specializing in autonomous systems, artificial intelligence, sensors,...

Countering small drones has become increasingly difficult as unmanned aircraft grow smaller, cheaper, and more numerous. Traditional radar systems can detect many aerial threats,...

Modern military operations depend heavily on the electromagnetic spectrum. Radar systems, communications networks, GPS signals and electronic warfare equipment all compete for access to...

Modern military operations depend heavily on satellite navigation, secure communications and precise timing. That dependence creates vulnerabilities: GPS and other satellite signals can be...

The new microwave photonic radar can track 10 hypersonic missiles traveling up to Mach 20 and distinguish between false positives and genuine targets with...

Scientists have designed a camera that copies the unique structure of a cat’s eye, significantly enhancing imaging capabilities in low-light conditions and complex backgrounds....

Chinese researchers have reportedly developed a cutting-edge high-power microwave (HPM) weapon capable of generating electromagnetic pulses equivalent to the energy released in a nuclear...

The growing frequency of unauthorized drone activity near U.S. military facilities is highlighting a critical vulnerability in defense infrastructure—namely, the limited capacity to detect...

In a step toward smarter and more responsive military gear, researchers in South Korea have unveiled a new type of fabric-based technology that transforms...

At the Changchun air show in northeast China, engineers displayed combat drones built from retired J‑6 fighters, confirming plans to convert the Cold War–era...

Modern infrastructure is increasingly dependent on tightly connected digital systems. Power grids, transport networks, hospitals, and communication platforms all rely on data flows that...

Robots intended for combat support or hazardous-duty missions typically rely on pre-programmed actions or remote-control interfaces, limiting how precisely they can mimic human movement....

Operating aircraft over heavily defended territory has become increasingly difficult as air-defense systems grow more capable and networked. Traditional surveillance platforms struggle to remain...

As electric and autonomous vehicles take on more driving tasks, understanding exactly how a car behaves at any given moment becomes critical. One of...

Navies are facing a growing challenge offshore: how to maintain persistent awareness and protection across vast maritime areas without tying up crewed vessels for...

Operating helicopters in the North Atlantic has always carried high risk. Harsh weather, long distances, and the growing presence of submarines make maritime aviation...

Air and missile defense planners are facing a rapidly widening threat spectrum. Beyond traditional aircraft, modern forces must contend with ballistic missiles, cruise missiles,...

Countering long-range attack drones has become a persistent challenge for air defense planners. Low-cost, long-endurance UAVs can loiter for hours and strike far from...

Drone swarms have become one of the defining threats of the current Ukraine-Russia conflict. Low-cost unmanned aerial vehicles can be launched in large numbers...

As unmanned aircraft become central to modern combat, another challenge is emerging: what happens after a drone goes down. Crashed systems can contain sensitive...

Loitering munitions have become a central feature of modern conflict, offering a relatively low-cost way to strike targets with precision. However, many existing systems...
