Understanding whales has historically been a time-consuming and difficult task for scientists, not least because these magnificent mammals spend about 95% of their days underwater. Now, drone technology is offering a new frontier of vital research.
-
The US Army has chosen the enhanced vertical liftoff V-BAT UAS developed by Northrop Grumman and Shield AI to take part in the Future Tactical Unmanned Aircraft System competition to find a replacement for the venerable RQ-7B Shadow tactical drone.

Since we first got wind of Saildrone's autonomous USVs back in 2018, they've mapped miles of ocean floor, chased hurricanes, and surveyed remote regions. Now the company is adding a new vessel to tackle near-shore mapping and maritime surveillance.

In July last year, Saildrone launched one its sensor-packed unmanned aquatic drones on a voyage of discovery in the North Pacific, tasked with filling in ocean mapping blanks around Alaska's Aleutian Islands as well as off the coast of California.

BAE Systems has unveiled a fascinating new autonomous, hybrid, VTOL UAV for military use. The STRIX, developed in Australia, folds to fit inside a shipping container, and is capable of carrying 160 kg (353 lb) of payload over 800 km (500 miles).

A remarkable group of drone prototypes from a team at the University of Tokyo takes multirotor complexity to the next level. These hypnotic flying robots are able to change their structural shape mid-air, creating some unprecedented capabilities.
-
These strangely-shaped twisted-loop propellers look like a revolutionary (sorry) advance for the aviation and marine sectors. Radically quieter than traditional propellers in both air and water, they're also showing some huge efficiency gains.
-
The US Army has awarded Eprius a contract worth US$66.1 million to deliver prototypes of a new microwave weapon called Leonidas that is capable of bringing down entire swarms of enemy drones in a single burst, while leaving friendly aircraft intact.
-
Racing quadcopters are insanely light, quick and agile, but they're not typically known for their top-speed figures. Mechanical engineer and hobbyist Ryan Lademann builds his own frames to push the limits, and he's now bagged a Guinness World Record.
-
Researchers at Northwestern Polytechnical University in Xianyang, China, have demonstrated a drone that never needs to land, thanks to a remote charging system that delivers power via an adaptive, target-tracking laser on the ground.
-
Startup Skydio’s latest approach to self-charging drones involves affordable and compact base stations that can be deployed in a variety of settings, as it looks to put self-sufficient aircraft in the hands of more and more users.
-
NASA has contracted Virginia's Advanced Air Company to design and build a prototype of a new type of transition-capable eVTOL drone – a tilt-wing concept that uses aerodynamic forces instead of actuators to tilt the wings and propulsion systems.
