Modern electronic warfare depends on the ability to detect, identify, and analyze electromagnetic signals quickly. As military communications, radars, and sensors become more numerous...

Written By Or Shalom Over the past decade—and particularly in recent years—the lower airspace domain has evolved from a regulatory gray area into one of...

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

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

Maintaining reliable communications in congested or contested environments remains a growing challenge for military and unmanned systems. Most fielded radios still rely on omnidirectional...

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

Unmanned aerial systems are taking on increasingly complex missions, from reconnaissance and border monitoring to strike operations and electronic surveillance. But as drones move...

Detecting hypersonic missiles remains one of the most difficult challenges in modern air defense. Traveling at speeds above Mach 5, these weapons generate extreme...

Conventional firearms rely on chemical propellants, which bring a set of well-known limitations: noise, visible signatures, and fixed levels of force. In certain scenarios,...

Conventional firearms rely on chemical propellants, producing noise, flash, and visible signatures that can limit their use in certain operational scenarios. In law enforcement...

The growing use of drones in both military and civilian environments is creating a new type of threat that traditional air defenses are not...

Modern air operations increasingly depend on the electromagnetic spectrum. Radar, communications links, targeting networks and drone control systems all rely on uninterrupted access to...

Low-cost drone swarms have exposed a growing imbalance in modern air defense. Small, unmanned aircraft can cost only a few thousand dollars and be...

Modern technology depends on precision, yet many critical systems operate in environments filled with invisible magnetic noise. Power infrastructure, medical imaging, aerospace platforms, and...

Technology designed to detect earthquakes is now showing unexpected potential in airspace monitoring. Researchers at the University of Alaska Fairbanks have demonstrated that seismic...

A new weapon design under development by researchers linked to China’s People’s Liberation Army (PLA) is drawing international attention for its potential capabilities in...
