Stealth

Robotic submarines are poised to become a major addition to the fleets of the world's major navies and as the technology matures more attention is being paid by the likes of the European Defence Agency (EDA) to making them quieter and stealthier.

On December 26, 2024, in broad daylight, China took to the skies with the test flights of two presumed sixth-generation delta-wing fighter jets. The more documented of the two, the Chengdu delta-wing craft, has been tentatively identified as the J-36.

Northrop Grumman has released a photo of the Series Hybrid Electric Propulsion AiRcraft Demonstration (SHEPARD) XRQ-73 stealth drone X-plane that it has built for DARPA and is expected to fly by the end of the year.

Although snapshots of the B-21 Raider nuclear bomber in flight have been taken previously by the public, these weren't with permission. Now the United States Air Force has released the first official images of the aircraft in the air.

Stealth technology may not be very stealthy in the future thanks to a new quantum radar system that uses the phenomenon of quantum entanglement to eliminate heavy background noise, thereby defeating stealth anti-radar technologies to detect incoming aircraft and missiles with much greater accuracy.

To combat the lower-frequency, directed anti-stealth radar-targeting systems being developed, researchers have developed a thin electronic material that may help hide aircraft from missile-targeting radar.

Unlike most other sea creatures, sea lions use their forelimbs instead of a tail for propulsion. They also leave virtually no wake as they travel through the water. With an eye towards applying this design to human technology, a scientist has developed a robotic sea lion flipper.

BAE Systems Taranis Unmanned Combat Aerial Vehicle (UCAV) has flown for the first time in a full stealth configuration, making it almost invisible to radar ... and bringing the day of the unmanned war plane that much closer to reality.

Computer monitors are big and splashy, and can reveal sensitive information or activities to bystanders. An additional layer of security (and fun) can be added to your computer's LCD display by removing your display's outer polarizing filter, and using polarizing sunglasses instead.

Rolling out of a hangar on the former Soesterberg Air Base in Utrecht, The Netherlands, is a black, angular shape that looks like a stealth hermit crab crossed with an airport waiting lounge: Secret Operation 610.

The Qaher F-313 (Dominant F-313) is a new Iranian designed and built combat that is claimed to have stealth capabilities.
