US sea drones evade detection using extremely low radar cross-sections that blend with waves. By employing silent electric propulsion and passive AI sensors, they operate in electromagnetic silence, remaining invisible to enemy radar.


‘Radar evasion’: What makes US sea drones difficult to detect or track

US sea drones use AI to navigate independently, and the US Navy is increasingly relying on uncrewed maritime operations. While these sea drones are heavily autonomous, their actual operational independence involves a complex balance of artificial intelligence and necessary human oversight.

Rescues and radar: How autonomous are US sea drones really?

From the F-22’s AN/APG-77 to future phased arrays scan skies in seconds with microsecond beam steering, long-range detection, and rapid multi-target tracking. But the real breakthroughs lie in how fast these systems adapt in real combat conditions.

Quantum radar could soon spot even the best stealth jets, making them visible in battle. By using entangled photons to spot aircraft that hide from traditional radar, this new tech may end the era of invisible warplanes and change how nations fight and defend their skies forever.


Quantum radar: The tech that could end fighter jet stealth as we know it

Five materials, including metamaterials, graphene, MXene, carbon nanotubes, and advanced ceramics, could revolutionise aircraft stealth technology. Which materials will shape invisible aircraft? Know more below.

Stealth is a major capability of modern military equipment to go invisible on enemy radar provide a major advantage on the battlefield as well. Growing menace of drones as seen in Russia Ukraine war has also got researchers crashing their head but new radar system can make the jets and drones lose the cloak of stealth. Watch in for more details!

Will quantum radar keep drones off the battlefield?

India may soon ink a massive multibillion-dollar deal with Russia to boost its air defence infrastructure. According to media reports, New Delhi is in advanced talks with Moscow to acquire 'Voronezh' series radars for $4 billion that can be deployed to monitor and detect aerial threats such as ballistic missiles, fighter jets, and ICBMs.

According to a new report, Chinese researchers say they have developed a new radar technology that is aimed at detecting the F-22 and other stealth aircraft with remarkable accuracy. The findings come at a time when the U.S. has stationed its fifth-generation fighter jets in an airbase in Japan, with an eye on China.

Anything with ‘aliens’ in its title these days most often tends to be more sensational than scientific. The topic has been on human civilisation's mind for centuries and as technology developed, we have focussed our scopes and antennae to find hints of alien life in far corners of space.

Aliens might find us through radio signals leaked by our mobile phone towers, says study

Indian authorities on Saturday searched the premises of Bengaluru-based Edtech giant Byju's. Byju's is under the radar for alleged violation of India's foreign exchange laws. Byju Raveendran, the co-founder and CEO, however, denied any wrongdoing.
