The Leonidas system has shown up in a moment when the Department of Defense was recognizing a critical need and as promised the technology they provided was proven capable just in time to address the problem America barely knew it had...
It uses a directed energy weapon rather than an interceptor system to take out incoming threats, but rather than being a point and shoot offensive weapon, Leonidas is meant to provide defensive area coverage creating less a contiguous force field in the surrounding area and more an area of denial where no unfriendly drone system can operate. The core of the Leonidas system is its use of high power microwave energy fired in beams that create an electromagnetic pulse or EMP. EMPs are nothing new in Modern Warfare and their effects are well known, primarily their ability to disable electronic systems, but rather than say the natural EMPs that come from lightning strikes or the uncontrolled EMPs that result from the detonation of nuclear weapons, the EMPs that come from the Leonidas system are able to be channeled precisely, cutting in a wide beam they can fry anything in their path -- neutralizing, say, an oncoming drone swarm all at once, or they can focus on precise individual targets sniping drones out of the sky one by one as soon as they violate the perimeter.
That is a massive improvement over any laser based system which would offer only the capability to fire against a single target at a time using specialized transistors rather than traditional magnetrons to generate its microwave beam.
Leonidas is considered more compact than would otherwise be expected for a weapon of this kind, and at a relatively low cost of energy expenditure, it can focus a beam for a relatively long duration of time or fire off shots in rapid succession, relying on a digitally beamformed antenna. That beam is kept tight and highly precise such that it's unlikely that nearby friendly drones will be impacted when the beam is targeted against a single foe.
Leonidas can fire very rapidly without overheating, and its effect on a target is near instantaneous, rather than needing to train the beam on the target for any length of time.
It doesn't require reloading, and its voltage is low enough that humans nearby aren't in danger from its emissions.It's efficient it's easily transported, and by all indications it's highly effective against the consumer grade drone technology that the US military is so worried about. Any drone of that sort that comes into Leonidas's protective bubble will be fried regardless of the specific internal electronics that it features.
The positives to the Leonidas system go well beyond just that initially envisioned. As a towed trailer Leonidas now has been added to the Striker, an eight-wheel Armored Fighting Vehicle that's been in America's military employ since 2002. The Striker is well armored, it's armed for its own defense, and it can drive under its own power at speeds of up to 60 MPH (nearly 100 km per hour) while requiring minimal crew to operate the software.
Leonidus offers a range of benefits, but most important of all it's able to distinguish between friend and foe. That means that rather than simply creating an indiscriminant anti-drone force field, it creates a safe zone for friendly drones to operate while adversary devices have little hope of survival. Not only that but the friend-or-foe system could be programmed to fit a given situation, enforcing, say, a no fly zone, or ignoring adversaries outside of a certain critical zone.
The system has been adapted into an aerial attachment pod, giving it the ability to be fitted onto a heavy lift drone of its own and defend in midair.
It's also in the process of being miniaturized, and can at this stage be crammed into the back of a pickup truck without too much trouble. The technology is ruggedized, meaning that it can take a beating and continue to function, while the Leonidas Pod is adapted to integrate with all manner of existing UAVs and could probably be grafted onto manned aircraft as well, and because Leonidas targets the electronic systems of a drone directly rather than simply cutting it off from radio operators it's just as successful in stopping fully autonomous drones that don't require active operator control in order to function.
Finally, Leonidus has shown that it can be useful against not only aerial drones but sea drones and at the time of writing tests have already demonstrated that it can disable a sea vessel's outboard motor in addition to basically any other sort of electronics that an operator could point it at.
Perhaps most important out of any of its design elements is the focus on keeping the Leonidas system modular and easily adaptable. This is a feature of many modern US military technologies.
I’ll believe it when I see it being successfully employed on the battlefield.
Care to name the last weapon system the shysters in the MIC gave us that actually performed as promised? After massive, massive cost overruns and further delays, perhaps we will get a third of whatever they’re designing actually operating at one time.
Well, these guys certainly. From last June...
Revolutionary Dronebuster® FS Revealed, Provides New Capabilities for Fixed-Site Drone Defense
From a couple of days ago...
Follow the money...
Of course — if the electronics and computer capacity and algorithms of a large AESA are tuned against relatively small drones. My guess is that the point of the new system is that it is cheaper and more capable of wide scale deployment and use by minimally trained personnel.
It is not a wideband EMP device.
Looks like a phased array device, which makes me a little doubtful about this device. I wonder how it would perform against a simple corner reflector(?)
The EMP effect is apparently generated and focused using a phased array.
Be sure to allow China and Russia and Iran to steal the tech.
yes, but the main difference is in the solid state RF element front ends where conversion from/to baseband where the control computer can work its beamforming and other processing magic...
Good point.
Many never realize that military industrialists make products designed to be sold to government dicks with they own motives and loyalties.
How well it works in the field (or if it works at all) is secondary.
Don’t such systems have lower peak power than AESA radar?
It depends on the use/purpose. Yes a corporate fed high power phased array (e.g., phase shifters are Passive at RF but you’d lose the DBF for multiple simultaneous beams and the direct DSP the central computer could do. The DBF becomes more desirable the higher you can push the individual element power, say over 50-100 watts at each element module in the array
Try to stop all of these drones.
