Sonar

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

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

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...

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...

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

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,...

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...

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

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

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

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