Sonar

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

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...

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

Unexploded bombs, naval mines, and artillery shells left behind by past conflicts remain a hazard in coastal waters around the world. Buried beneath sand...

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...

Chinese scientists developed an affordable and highly sensitive version of a Superconducting Quantum Interference Device (SQUID), according to research published in late 2023. SQUIDs are...

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

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

Getting personnel into remote or hostile territory normally requires aircraft, helicopters or prepared launch infrastructure. Those options can be noisy, detectable and dependent on...

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...

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

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

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...

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...

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

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

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

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...

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

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

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...
