Protecting a major port from drones presents an increasingly difficult security problem. Maritime facilities cover large areas and contain ships, fuel infrastructure and other...

Inspecting the underside of a ship is a difficult but important security task. Hulls can conceal structural damage, foreign objects or potentially dangerous devices...

One-way attack drones have created an increasingly difficult equation for air-defense forces. Aircraft such as the Shahed-136 are relatively inexpensive, can be launched in...

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...

Modern military operations generate enormous amounts of information. Intelligence reports, satellite imagery, drone feeds, logistics updates and battlefield reports must all be analyzed before...

Detecting extremely weak magnetic fields is useful in everything from medical imaging to industrial monitoring, but sensitivity comes with a fundamental problem: noise. As...

Modern navigation depends heavily on satellite signals, but GPS is not always available. Signals cannot reliably penetrate underground or deep underwater and can also...

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...

As organizations begin deploying teams of AI agents to handle complex tasks, cybersecurity is becoming a growing concern. In these multi-agent systems, several large...

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...

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...

As militaries and security organizations deploy growing numbers of drones, robots, and autonomous systems, a new challenge is emerging: each platform comes with its...

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

Protecting critical systems becomes especially difficult once an attacker gets inside the device itself. Conventional cybersecurity tools can monitor network traffic, identify known vulnerabilities...

Air defense systems today must contend with a wide range of fundamentally different threats: ballistic missiles traveling at high speeds and altitudes, fighter aircraft,...

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...

Traditional rocket launches depend on large, permanent spaceports containing launch pads, control systems and specialized ground equipment. That infrastructure is expensive, geographically fixed and...

Modern processors routinely predict what software will do next so they can begin executing instructions before they are actually needed. This technique, known as...

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

Maritime surveillance requires military forces to monitor enormous areas while identifying ships, submarines and other potential threats as quickly as possible. Crewed patrol aircraft...

Flying autonomously through complex environments requires more than knowing where a drone is. The aircraft must continuously understand what surrounds it, distinguish open routes...

Inspecting pipelines, power lines and transportation corridors presents a difficult logistical problem. These assets can stretch for hundreds of kilometers through remote terrain, making...
