DARPA

We got a glimpse at what a new cross between a helicopter and a jet aircraft might look like after Bell released a new image. It's of a model used in wind tunnel tests of its entry in DARPA's Speed and Runway Independent Technology (SPRINT) program.

Sometimes you see a vintage plane that makes you scratch your head. Case in point is the US Air Force's X-29 of the 1980s that looks like a fighter with the wings stuck on backwards. Was this a daft mistake or a great leap forward? Let's have a look.

Boeing subsidiary Aurora Flight Sciences is working on a high-speed VTOL military aircraft as part of DARPA's Speed & Runway Independent Technologies (SPRINT) program. Early ground effect testing has demonstrated its fan-in-wing vertical lift system.

Aurora Flight Sciences has released a new video of its revolutionary wing-in-ground-effect Liberty Lifter concept aircraft that it's developing for DARPA. The aircraft uses ground effect to lift heavy loads without the need for an airstrip or ship port.

Treating life-threatening bloodstream infections in combat situations is challenging, especially when the pathogen responsible is unknown. So, DARPA has called on Harvard’s Wyss Institute to use its groundbreaking biotech to fight this deadly threat.

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.

Looking like a miniature B-21 bomber, DARPA has shown off its new Series Hybrid Electric Propulsion AiRcraft Demonstration (SHEPARD) program aircraft. Called the XRQ-73, the long-range hybrid-electric drone is scheduled to fly by the end of the year.

Northrop Grumman has revealed more details on its robotic Manta Ray submersible in some new videos. These include a 4K 360° tour of the first test dive and a rundown on the project with images from never-before-seen angles.

Bell has been selected as one of two companies for Phase 1B of DARPA's Speed and Runway Independent Technologies (SPRINT) X-Plane program to create a prototype High-Speed Vertical Takeoff and Landing (HSVTOL) aircraft for the US military.

Sikorsky has advanced to the next phase of a DARPA project to develop an unmanned VTOL aircraft capable of flying all-weather missions from ships or land. The rotor blown wing VTOL tail-sitter is currently undergoing flight testing.

Aurora Flight Sciences has revealed its latest concept for a low-drag, fan-in-blended-wing body design for DARPA's Speed and Runway Independent Technologies (SPRINT) program aimed at producing a high-speed VTOL aircraft for Special Forces missions.

DARPA has unveiled more of its mysterious Manta Ray robotic sub, with impressive new images of the prototype Uncrewed Underwater Vehicle (UUV) undergoing its first sea trials off the coast of Southern California. And it's somewhat of a beast.
