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...

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...

AI coding agents are increasingly able to browse websites, download files, write programs and execute commands with limited human supervision. Those capabilities make them...

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...

Designing an efficient drone propeller involves far more than choosing the right diameter or number of blades. Small changes in blade geometry can affect...

End-to-end encryption can keep the contents of a conversation private, but it cannot protect users if an attacker manages to take over the account...

Persistent surveillance is one of the biggest challenges in modern military operations. Conventional drones are limited by battery capacity or fuel, requiring frequent landings...

Small military drones are taking on increasingly complex missions, from reconnaissance and target tracking to autonomous navigation and coordinated swarm operations. Yet many of...

Large defense and government organizations often manage information across hundreds of disconnected sources. Reports, spreadsheets, databases, planning documents, and operational updates are typically stored...

Webcams, microphones, monitors and other computer accessories often appear to be simple peripherals, but many are effectively small computers with their own processors, memory...

The rapid spread of military drones has created a growing problem for air-defense forces. Many attack drones are inexpensive to produce, yet they are...

Protecting large industrial sites, airports, campuses and critical infrastructure often requires continuous patrols over wide areas. Autonomous security robots are increasingly being used to...
