U.S. Military Plans to Deploy Laser Weapons by 2025

Posted by in categories: drones, economics, military

The DEIMOS laser weapon is seen here in illustration, capable in the near future of knocking a drone, ordinance, aircraft and even missiles out of the sky.


It is the economics of laser weapon systems that makes this type of ordinance so attractive. At the moment various vendors like Lockheed Martin, and Raytheon are building 50 Kilowatt laser weapons. But there is no determining limit on the strength. The U.S. Department of Defense estimates a 100 Kilowatt laser could easily handle a drone, a small boat, a shell fired by artillery, and even a mortar. For a cruise missile, the estimate is a 300 Kilowatt laser, and for a ballistic missile or hypersonic weapon, a 1 Megawatt laser. Lockheed Martin is already testing a 300 Kilowatt version of DEIMOS.

The US Navy is looking at 100 Kilowatt versions of DEIMOS for its ships and looks like it will replace arming vessels with rail gun technology which now appears to be considered obsolete. Rail guns were high-speed ordinance systems designed to knock down incoming cruise missiles but when costs are compared the laser has the technology beat.

MIT’s latest drone propellers are very quiet and efficient

Posted by in category: drones

They consist of two blades looping together so that the tip of one blade curves back into the other.

The MIT Lincoln lab has produced some new devices for aircraft and drones that make some impressive efficiency gains and are radically quieter.

“The toroidal propeller allows a small multirotor unpiloted aircraft, or drone, to operate more quietly than current drones that use propeller forms unchanged since the beginning of aviation,” said a statement by the lab.

A drone that never lands? Scientists in China test lasers to keep drones aloft ‘forever’

Posted by in categories: drones, military

The method would charge drones while their airborne, meaning they would never have to land.

A team of researchers from the Northwestern Polytechnical University (NPU) in China has developed a method for using high-energy laser beams to keep drones airborne “forever,” according to a report from The South China Morning Post.

Laser-powered drones could remain aloft “forever”.

Can Drones And Artificial Intelligence Keep Us Safe From Sharks?

Posted by in categories: drones, robotics/AI

You might be rolling your eyes as you see the drone take off to the skies and hover over the Australian coastline, camera angled straight down towards the glistening turquoise water. “Another TikTok influencer trying to get the perfect shot,” you grumble to yourself. But if you look closely at the pilot, you’ll notice they’ve got a sign next to them that says “Keep Clear” in bright yellow and red letters. This is no TikTok influencer.

It’s an Australian surf lifesaver, using the above drone to spot sharks at the beach before they get too close to swimmers like yourself.

How drone deliveries could save lives and make streets safer

Posted by in categories: drones, robotics/AI

At CES 2023, industry experts weighed in on why drones should be your next delivery vehicle.

Drone deliveries could help reduce unnecessary deaths on roads and improve the environment, industry experts explained Friday.

For example, delivering that hamburger helper via a drone versus someone getting in their car and driving to a place…

5 Budding Engineers Create Submersible Submarine-Cleaning Drone in Just 6 Weeks

Posted by in categories: drones, engineering

“Five strangers were pulled together” in an engineering challenge to find a solution to a real-world problem.

Engineering researchers of an innovative academy program have designed a Submersible Remotely Operated Vehicle (SROV) in a span of six weeks after accepting the U.K. Navy’s challenge.

“I was skeptical at first that we could pull off such an ambitious project within the timeframe,” said Dylan Brennan, project team lead, a nuclear graduate working for Jacobs.

Amazon starts drone delivery trials in California and Texas

Posted by in category: drones

Amazon has launched drone delivery trials in a couple of new locations in California and Texas.

David Carbon, vice president of Prime Air Amazon, announced the development on LinkedIn. His post included a photo (below) showing one of its drones carrying a small box on the end of a tether.

“First deliveries from our new sites in Texas and California,” Carbon wrote in his post. “Couldn’t be prouder of the amazing people that make up Prime Air. These are careful first steps that we will turn into giant leaps for our customers over the next number of years.”

Meta-optics: The disruptive technology you didn’t see coming

Posted by in categories: cyborgs, drones, mobile phones, robotics/AI

Robots and autonomous cars will have eyes that see much more than the human eye is capable of, a review of the growing field of meta-optics has found.

Meta-optics is advancing science and technology far beyond the 3,000-year-old optical paradigm that we rely on for the visual , such as through cameras in our mobile phones, the lenses in microscopes, drones, and telescopes. Optical components are the technology bottleneck that meta-optics aims to transform, bringing the stuff of science-fiction stories into everyday devices.

The field, which blossomed after the early 2000s thanks to the conceptualization of a material with that could form a perfect lens, has grown rapidly in the last five years and now sees around 3,000 publications a year.
