When GPS Goes Dark, Hypersonic Weapons Could Navigate by the Stars
Hypersonic vehicles create an unusually difficult navigation problem. Traveling at several times the speed of sound leaves little room for positioning errors, while satellite...
These Floating Gun Platforms Are Built to Guard Ports From Drones
Protecting a major port from drones presents an increasingly difficult security problem. Maritime facilities cover large areas and contain ships, fuel infrastructure and other...
A New Decoy Drone Can Make Itself Look 20 Times Larger...
Modern air-defense systems depend heavily on radar to determine which objects in the sky deserve attention. That creates an opportunity for deception: if a...
This Skin-Cell-Sized Sensor Could One Day Help Detect Submarines
Detecting extremely weak magnetic fields is useful in everything from medical imaging to industrial monitoring, but sensitivity comes with a fundamental problem: noise. As...
A Tiny Levitating Gyroscope Could Make GPS-Free Navigation More Accurate
Modern navigation depends heavily on satellite signals, but GPS is not always available. Signals cannot reliably penetrate underground or deep underwater and can also...
The Biggest Thing Holding Back Next-Gen Radar? Heat
Gallium nitride has become an important material for high-performance radar, communications and electronic warfare systems because it can handle far more radio-frequency power than...
Butterfly-Inspired Tech Could Give Tiny Robots Some Serious Muscle
Building robots at microscopic scales creates an unusual engineering problem: even the simplest movements become difficult to produce. Conventional motors, gears and hydraulic systems...
The Battlefield Is Full of Invisible Signals—This Device Finds Them
Modern battlefields are increasingly crowded with radio-frequency signals. Drones, aircraft, ships, communications equipment and electronic warfare systems all transmit across the electromagnetic spectrum, creating...
This Autonomous Aircraft Can Carry 10 Missiles Without a Pilot
Attack helicopters are facing a growing challenge on today's battlefield. The widespread use of inexpensive drones, loitering munitions and persistent aerial surveillance has made...
This Tiny Cyber Probe Can Tell When a Device Has Been...
Protecting critical systems becomes especially difficult once an attacker gets inside the device itself. Conventional cybersecurity tools can monitor network traffic, identify known vulnerabilities...
€3 Billion Deal Brings Israeli Multi-Layered Air Defense to Greece
Air defense systems today must contend with a wide range of fundamentally different threats: ballistic missiles traveling at high speeds and altitudes, fighter aircraft,...
The Javelin Missile Is Getting a Next-Generation Infrared Upgrade
Modern armored vehicles are increasingly equipped with camouflage, thermal-management technologies and other measures intended to make them harder to identify and engage. At the...
The Next Defense Against GPS Jamming Could Be Quantum-Based
Modern military operations depend heavily on satellite navigation, secure communications and precise timing. That dependence creates vulnerabilities: GPS and other satellite signals can be...
This Surveillance Drone Can Take Orders Directly From a Crewed Aircraft
Maritime surveillance requires military forces to monitor enormous areas while identifying ships, submarines and other potential threats as quickly as possible. Crewed patrol aircraft...
This Technology Gives Autonomous Drones Better Eyes in the Sky
Flying autonomously through complex environments requires more than knowing where a drone is. The aircraft must continuously understand what surrounds it, distinguish open routes...
This Drone Can Patrol Hundreds of Kilometers of Critical Infrastructure
Inspecting pipelines, power lines and transportation corridors presents a difficult logistical problem. These assets can stretch for hundreds of kilometers through remote terrain, making...
This Solar-Powered Drone Could Watch the Battlefield for Weeks
Persistent surveillance is one of the biggest challenges in modern military operations. Conventional drones are limited by battery capacity or fuel, requiring frequent landings...
This New Chip Compresses and Protects Wireless Data at the Same...
As wireless networks carry ever-growing amounts of data, communication systems face increasing pressure to transmit information faster while consuming less power and bandwidth. This...
Four Times More Processing Power—Without a Bigger Drone
Small military drones are taking on increasingly complex missions, from reconnaissance and target tracking to autonomous navigation and coordinated swarm operations. Yet many of...
This One-Wheel Robot Could Replace Routine Security Patrols
Protecting large industrial sites, airports, campuses and critical infrastructure often requires continuous patrols over wide areas. Autonomous security robots are increasingly being used to...
New Drone System Finds Underwater Explosives Hidden for Decades
Unexploded bombs, naval mines, and artillery shells left behind by past conflicts remain a hazard in coastal waters around the world. Buried beneath sand...
This Color-Shifting Material Could Transform Robotic Precision
Vision has improved dramatically in modern robots, but touch remains one of the most difficult human senses to reproduce. Detecting exactly how much pressure...
