Small unmanned aerial systems have become one of the most persistent threats on modern battlefields. Commercially derived drones are now widely used for reconnaissance,...

The rapid rise of small drones has created a difficult challenge for air-defense planners. Commercial quadcopters and other low-cost unmanned aircraft can be deployed...

Protecting digital information usually depends on cryptographic keys, which are random sequences used to encrypt and decrypt data. The security of everything from smartphones...

The rapid growth of battlefield drones has forced militaries to rethink short-range air defense. Small, unmanned aircraft are inexpensive, widely available, and increasingly capable...

Modern air-defense systems face an increasingly difficult task. Drones, cruise missiles, helicopters, rockets, and high-speed aircraft can all appear simultaneously, often operating at different...

One of the greatest challenges facing modern air defense is no longer the single drone, but swarms of dozens or even hundreds of unmanned...

The rapid spread of small drones has created a growing challenge for air-defense forces. Many of the drones now used for reconnaissance, targeting, and...

Modern artillery faces two growing challenges. The first is range. As adversaries field longer-range weapons, artillery units must be able to strike targets from...

Protective gear such as helmets and body armor must strike a difficult balance. Materials need to be strong enough to withstand impact, but not...

Small drones have become one of the most difficult threats for infantry units to counter. Their speed, size, and maneuverability make them challenging targets...

Explosive ordnance disposal teams, special operations units, and emergency responders often face a difficult dilemma: gaining information about a potentially dangerous area without exposing...

Submarine warfare depends heavily on one weapon: the heavyweight torpedo. Unlike missiles, which can be observed and tracked throughout much of their flight, torpedoes...

Modern drone operations increasingly face a common challenge: GPS cannot always be trusted. Electronic warfare systems, signal interference, and environmental factors can degrade navigation...

The growing use of drones is creating new security challenges far beyond traditional battlefields. Ports, shipping lanes, offshore platforms, and commercial vessels are increasingly...

Modern military systems are becoming increasingly software-driven and interconnected. Sensors, drones, command-and-control platforms, electronic warfare systems, and weapons must all work together across air,...

The rapid proliferation of drones has created a new challenge for military forces and critical infrastructure operators. Modern threats range from small commercial quadcopters...

Operating military vehicles in mountainous terrain presents a unique engineering challenge. As altitude increases, air becomes thinner, reducing the amount of oxygen available for...

Air forces around the world are increasingly looking for ways to expand combat capability without placing additional pilots in harm’s way. Modern fighter aircraft...

Smartphone LiDAR sensors have become common in high-end devices, mainly supporting augmented reality features and depth sensing for photography. But despite their growing capabilities,...

The unmanned systems market continues to expand, but alongside developing new platforms, manufacturers must also overcome challenges related to financing, production, and international market...

Modern battlefields are saturated with electronic activity. Drones, radars, radios, data links, and command networks continuously emit signals that can reveal the location and...

Mortar teams depend on fire-control systems to calculate firing solutions, manage targeting data, and coordinate indirect fire missions. Traditionally, many of these functions have...
