Sonar

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,...

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

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...

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...

Underwater operations present a persistent challenge for both humans and machines. Visibility is often limited, communication is constrained, and navigation can quickly become uncertain....

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

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

On modern battlefields, artillery and mortar fire can strike within seconds of launch. Detecting the origin of gunfire quickly is critical for both force...

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...

German firm Euroatlas has revealed its latest innovation in underwater surveillance technology: the Greyshark, an autonomous underwater vehicle (AUV) designed for long-distance reconnaissance, patrol,...

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

Modern naval forces face an increasingly complex underwater picture. Quieter submarines, dense maritime traffic and the growing risk of seabed mines make persistent undersea...

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...

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...

Unmanned minehunting technologies are gaining momentum, and the transition to the widespread use of autonomous systems in mine countermeasures is becoming a reality in...

BAE Systems has secured a $70 million contract to manufacture missile tubes for the U.S. Navy’s Block VI Virginia-class submarines, significantly enhancing the firepower...

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...

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

Monitoring activity beneath the ocean surface remains one of the most complex challenges in maritime operations. Traditional sonar systems provide valuable acoustic data, but...

India’s Defense Research and Development Organisation (DRDO) has unveiled a new class of man-portable autonomous underwater vehicles (MP-AUVs), designed to make mine detection faster,...

Naval mines remain a quiet but persistent danger. Cheap to deploy and difficult to detect, they can block ports, restrict maneuver, and threaten both...

China is reportedly developing a new, secret submarine that has raised concerns among defense experts worldwide. Built at the Guangzhou Shipyard, the submarine is...
