Sonar

Detecting extremely weak vibrations usually requires complex electronics, amplification circuits, and continuous signal processing. Whether in microphones, environmental monitoring systems, or biomedical devices, improving...

Calling all defense-tech startups! Don’t miss out on the exciting opportunity to participate in the Defense-Tech Startup Competition at the Global Defense Tech Summit...

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

Undersea threats are becoming harder to counter. Modern torpedoes are faster, quieter, and more capable of adjusting their course mid-run, leaving ships with very...

Researchers from Princeton and MIT have uncovered a method for intercepting underwater communications, challenging long-standing assumptions about the security of sonar transmissions. By using...

A team at MIT Lincoln Laboratory has developed a compact and inexpensive hydrophone that could transform underwater sensing across defense, industrial, and scientific functions....

Transmitting information between underwater and airborne systems has long posed a technical challenge. Sound behaves very differently in water compared to air due to...

As unmanned systems expand across air and land domains, underwater autonomy is becoming an increasingly important area of military development. Traditional submarines remain highly...

Operating helicopters in the North Atlantic has always carried high risk. Harsh weather, long distances, and the growing presence of submarines make maritime aviation...

Clearing naval mines remains one of the most dangerous and time-consuming tasks at sea. Mines can sit on the seabed for decades, threatening shipping...

Written by Or Shalom The Milipol TechX Summit (MTX) 2026, which opened on April 28th, 2026, at the Sands Expo Convention Center in Singapore, marks...

Airspace security has reached a frustrating paradox. Drones are easier than ever to detect, yet safely stopping them remains a persistent challenge. Airports across...

In a major advancement for naval defense, General Atomics Aeronautical Systems has demonstrated a breakthrough in unmanned aerial systems with the MQ-9B SeaGuardian UAV....

Naval mines remain one of the most disruptive and persistent threats in maritime operations. They are relatively simple to deploy but difficult and time-consuming...

Tracking submarines across vast ocean areas is one of the most resource-intensive missions in naval operations. Traditional platforms, such as crewed ships and aircraft,...

Australian naval divers from the frigate HMAS Toowoomba conducting minor repairs in international waters near Japan were exposed to active sonar pulses from Chinese...

Navies delivering aid are first to arrive on scene following a natural disaster. The vessels are vulnerable to groundings and collisions with submerged objects....

Small drone swarms are becoming increasingly difficult to stop using traditional air-defense systems. Conventional remotely operated gun turrets usually rely on mechanically rotating toward...

The growing use of small, low-cost drones is creating new challenges for air defense systems. Many of these platforms are difficult to detect using...

Sonobuoys are air-launched expendable, electro-mechanical anti-submarine warfare (ASW) acoustic sensors designed to relay underwater sounds of ships and submarines. The devices enable Navy ASW...

Locating submarines has always been one of the hardest challenges in maritime security. These vessels rely on stealth, operate across vast ocean areas, and...

Stories of invisible weapons tend to surface after fast, asymmetric operations. When defenders are overwhelmed quickly, especially by a smaller force, the search for...
