A Patriot missile costs $4 million. AeroVironment says its third-generation laser can do the same job for the price of a coffee.

Key takeaway

LOCUST X3 shifts counter-drone economics from million-dollar missiles to single-digit-dollar energy shots.

AeroVironment unveiled the LOCUST X3 directed-energy weapon at the AUSA Global Force conference in Huntsville, Alabama on 25 March 2026. The third-generation laser system delivers 20 to 35-plus kilowatts, defeats Group 1 through Group 3 drones, and costs approximately $5 per engagement.⁠¹

Consider the arithmetic. A single Patriot interceptor runs to roughly $4 million. Iran's Gulf campaign has consumed interceptor stocks at that price against Shahed-class drones costing $20,000 to $50,000 each. LOCUST X3 offers a ratio of roughly 800,000 to 1: effectively unlimited magazine depth at negligible marginal cost. No production contract has been announced, but AeroVironment describes the system as combat-tested across earlier generations.⁠²

AeroVironment is now positioning as a counter-drone company, not solely a drone manufacturer. The LOCUST X3 sits alongside its $135 million in recent Army contracts for Red Dragon strike and P550 reconnaissance platforms. Combined with the $200 million ESAero acquisition, the company is assembling a vertically integrated portfolio spanning both sides of the drone equation: attack and defence.

Deep Analysis

In plain English

When a $20,000 Iranian drone approaches a ship, the standard response is to fire a missile that costs $4 million. This is like using a Ferrari to swat a fly. LOCUST X3 fires a pulse of laser energy instead, for five dollars. There is no magazine to reload. As long as there is power, it can keep firing. The challenge is that lasers need a lot of electricity, which is harder to provide in a desert than on a warship.

Deep Analysis

Root Causes

The cost-exchange crisis driving directed energy investment is not new. It was documented in Ukraine by mid-2023, when Israeli Iron Dome operators confirmed per-intercept costs exceeding $50,000 against drones costing under $1,000. The lag between identifying the problem and fielding a solution reflects the decade-long development cycles of Pentagon acquisition programmes.

Iran's Gulf campaign converted the theoretical cost-exchange debate into an immediate operational demand signal, compressing the remaining procurement timeline from years to months.

What could happen next?

The Army E-HEL competition will likely cite LOCUST X3 performance data, accelerating the award timeline if combat deployment results are positive.
If directed energy scales to field deployment, it structurally removes the cost-exchange advantage that underpins Iran's and China's affordable mass drone doctrines.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: The Phalanx close-in weapon system achieved a similar economics breakthrough in the 1980s: replacing costly missile intercepts with high-rate cannon fire at negligible per-round cost, which became standard on US warships within a decade of first deployment in 1980.

Counter-parallel: The US Army's Tactical High Energy Laser (THEL) programme was declared cancelled in 2005 after 28 successful intercepts, because the chemical laser required too much logistical support for field deployment, illustrating the gap between demonstration performance and operational utility.

At $5 per engagement, LOCUST X3 represents a cost reduction of roughly 99.9988% against a $4 million Patriot intercept. Even accounting for AeroVironment's undisclosed system acquisition cost and power infrastructure, the break-even point against missile defence occurs after a trivially small number of engagements.

The market implication is larger. China filed 39 laser counter-UAS patents in the year to March 2025, versus 22 total US filings across all counter-drone methods. If directed energy becomes the dominant counter-drone technology, patent portfolio strength determines who can manufacture at scale without licensing costs.

Consensus view: The Missile Defense Advocacy Alliance and Paul Scharre (CNAS) both characterised LOCUST X3's cost ratio as the most significant counter-drone economics development since the Patriot cost-exchange crisis was identified in 2023, noting that unlimited magazine depth fundamentally changes the attacker's calculus.

Counter-view: Chinese PLA analysts (Academy of Military Science publications, January 2026) argued that high-power lasers require grid-scale power infrastructure that is unavailable in forward deployed environments, making the $5 per engagement figure misleading when generator and power conditioning costs are included.

Key tension: Whether directed energy can be reliably powered in austere forward operating environments, or whether its benefits are confined to fixed-site and ship-based defence.

Different Perspectives

Nigerian Air Force

The air force listed 12 Turkish Aksungur and two Chinese CH-4D armed drones on 25 October. No contract has been published, so these are plans.

Civilians in Western Sahara

A UN report of October 2023 records allegations of Moroccan drone strikes east of the berm. An aerial strike there in November 2022 reportedly killed six civilians, the UN said, citing Polisario and local media.

Thunder Tiger

The Taichung company said on 16 October that all 1,520 of its Gauntlet I attack drones passed inspection. Its MoU with AeroVironment covers fitting Switchblade to its uncrewed boats and ground vehicles and exploring joint production in Taiwan.

EDGE Group

The Emirati group said on 9 October it will supply glide bombs and guidance kits for the Royal Moroccan Air Force's armed drones. A separate memorandum explores making small arms and aero engines in Morocco.

Rajnath Singh

India's Defence Acquisition Council, which he chairs, approved about Rs 2.12 lakh crore of proposals on 26 October, including kamikaze drones and tank-mounted counter-drone systems. About 82 per cent of the value is to go to Indian industry, by the ministry's account.

Kongsberg

The Norwegian group said on 13 October it will invest more than 200m zlotys in a Pomeranian plant to build and maintain SAN counter-drone systems. It expects series output to begin in the first half of 2028.
