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...

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

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

Researchers at Worcester Polytechnic Institute (WPI) in Massachusetts are developing small aerial robots that rely on sound rather than cameras to navigate, offering new...

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

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

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,...

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

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...

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...

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

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

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...

Robots are increasingly deployed in environments that are unsafe or inaccessible for humans, from collapsed buildings and underground tunnels to industrial sites and disaster...

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...

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

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

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

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,...
