LOCUST X3 Laser on a Robot Vehicle: Air Defence With No Driver and No Bullets

A laser that drives itself into danger so soldiers do not have to: that is the LOCUST X3 laser weapon mounted on an uncrewed robot vehicle. At AUSA 2026, AeroVironment displayed its LOCUST X3 directed-energy system on American Rheinmetall's MUSKOX unmanned ground vehicle — a mobile, crewless drone-killer in the roughly 20 to 35 kilowatt class, aimed at Group 1 to Group 3 unmanned aircraft. No conventional ammunition, no driver in the cab, no crew beside the beam. The story here is not another fixed laser defending a base; it is a laser that moves with the force and risks a machine instead of a crew.

The Pairing: LOCUST X3 Meets MUSKOX

Each half of this display solves the other half's problem. LOCUST X3 is AeroVironment's laser weapon line, here shown in a configuration scalable across roughly the 20-35 kW band — power levels aimed squarely at the small-drone problem, Group 1 to Group 3 unmanned systems: the reconnaissance quadcopters, fixed-wing scouts and one-way attackers that now saturate every battlefield. Lasers in this class kill by heating a target's structure or electronics until it fails, dwelling the beam on a vulnerable spot for seconds at a time.

MUSKOX, American Rheinmetall's unmanned ground vehicle, supplies the mobility and the crewless part. An uncrewed carrier can be sent to the exposed position — the convoy's flank, the forward edge of a halt, the perimeter corner with the best sky view — without asking soldiers to sit in the most targeted vehicle in the formation. If the vehicle is found and struck, the loss is industrial, not human. That single fact changes how commanders can use a laser: aggressively, forward and expendably, instead of guarded at the rear.

Displayed together at AUSA, the combination is a concept pairing shown by the companies rather than a fielded Army programme — that distinction matters, and no fielding claim is made here. But concept pairings at AUSA are how future programmes introduce themselves, and this one is aimed at a gap every convoy commander already feels.

Mobility Is the Weapon: Lasers That Move With the Convoy

Most laser air defence shown to date defends a place: a base, a port, an airfield. Fixed sites can draw fixed power and cooling, and their lasers guard the same sky every day. Convoys, manoeuvre units and temporary positions have had no equivalent — their air defence must move, halt, move again, and survive on whatever power the formation carries. That is the problem the LOCUST X3 on MUSKOX is built to attack.

Picture the employment honestly. A convoy halts in open country — historically its most vulnerable minutes, with vehicles bunched and crews dismounted. The uncrewed laser vehicle takes the exposed flank position with clear sky, its beam director scanning while no soldier sits in the likely impact zone. Small drones approaching the halt meet a weapon with effectively unlimited shots, limited not by a magazine but by the power and cooling the vehicle can sustain. When the convoy moves, the robot moves with it — air defence as a travelling companion rather than a destination service.

No Bullets: The Power and Cooling Bill

A laser's magazine is its power supply, and that is both the promise and the limit of this entire class. LOCUST X3 fires no conventional ammunition: no shells to manufacture, ship, stockpile and reload, and a cost per shot measured in fuel and electricity rather than in interceptor missiles. Against cheap drones, that exchange is the whole point — the defender finally spends less on the shot than the attacker spent on the target.

But the bill arrives as heat and energy demand. A 20-35 kW beam requires substantially more electrical power than the beam rating alone suggests, because conversion losses become waste heat that must be removed continuously, in desert heat, from a vehicle that is also driving itself. Cooling capacity decides how many engagements the system can sustain in a burst; power storage and generation decide how long it can stay on station. Dust, rain and battlefield obscurants further tax any beam. These are not flaws unique to LOCUST X3 — they are the physics every mobile laser programme on earth is wrestling with — but they are why scalable power in the 20-35 kW range should be read as a deliberate, achievable class rather than a failure to reach higher numbers.

Target class honesty matters too. Group 1-3 drones are the stated prey: small, comparatively slow, thin-skinned aircraft whose numbers are the actual crisis in current wars. A mobile laser that reliably strips those from the sky above a convoy does not need to threaten cruise missiles to be valuable — it needs to be present, powered and crewless at the moment the swarm arrives.

Why Crewless Changes the Calculation

Air-defence vehicles are priority targets; radars and launchers draw fire precisely because they protect everything else. Putting the laser on an uncrewed vehicle breaks the attacker's maths. Striking the MUSKOX carrier costs the defender a replaceable machine; the crew that would have operated a manned equivalent is dispersed, supervising remotely or performing other tasks. Forward placement — the tactically correct, humanly expensive choice — becomes the default choice when nobody is aboard.

Crewless also means persistent. A robot vehicle does not tire on watch, and a laser that can hold an exposed overwatch position for extended periods, through the hours when human vigilance fades, closes the gap that small-drone operators most reliably exploit: the quiet hours at temporary positions.

Why It Matters

First, air defence is going mobile and crewless at the same time. LOCUST X3 on MUSKOX is not a base-defence laser on wheels; it is a convoy companion designed to occupy the most dangerous position in the formation with no crew at risk.

Second, the ammunition problem disappears — and the power problem replaces it. With no conventional rounds to exhaust, endurance is set by energy and cooling. Armies that master mobile power and thermal management will field the lasers that actually stay in the fight.

Third, the target set is the right one. Group 1-3 drones are the mass threat of current warfare; a scalable 20-35 kW system aimed precisely there, rather than at prestige targets, shows the industry finally building for the war that exists.

Frequently Asked Questions

What is LOCUST X3?

LOCUST X3 is AeroVironment's laser weapon system, displayed at AUSA 2026 mounted on American Rheinmetall's MUSKOX unmanned ground vehicle. It is scalable in roughly the 20-35 kW class and aimed at Group 1 to Group 3 drones.

What is the MUSKOX vehicle?

MUSKOX is American Rheinmetall's unmanned ground vehicle. In this pairing it carries the LOCUST X3 laser, providing mobile, crewless air defence that can take exposed positions without risking a crew.

Why put a laser on an uncrewed vehicle?

Mobility and survivability of people. The laser can move with convoys, occupy the most exposed flank or overwatch position, and remain on watch persistently — and if the vehicle is targeted and hit, no crew is lost.

What limits a mobile laser like LOCUST X3?

Power and cooling. The system uses no conventional ammunition, so its endurance is set by electrical generation, storage and heat removal, plus weather and obscurants that degrade any beam. Those factors govern how many Group 1-3 drones it can engage in succession.

Our Take

Most laser stories are about power records; this one is about placement. A 20-35 kW beam is unremarkable on a test range — but that same beam, on a robot that can be ordered into the exposed flank of a halted convoy at 3 a.m. with nobody aboard, is a genuinely new tactical fact. AeroVironment and American Rheinmetall have paired the right laser class with the right carrier for the drone war as it is actually fought: against small aircraft, in the open, against moving forces. Power and cooling will decide how long it can shoot, and a trade-show pairing is not a fielded programme — both caveats stand. But the direction is unmistakable. The future air defender may have no driver, no bullets and no fear — just a beam, a battery and orders to hold the dangerous corner. Laser wali gaadi aa gayi hai; ab usay medaan mein tikna hai.
