The headlines are breathless. The U.S. Navy fired a "drone-killing" LOCUST laser from the USS George H.W. Bush, and the defense establishment is taking a victory lap. They want you to believe we’ve reached a milestone in Directed Energy Weapons (DEW). They want you to think the era of cheap, swarming drones is over because we can now point a high-powered flashlight at them.
They are lying to you. If you liked this post, you might want to read: this related article.
What the Pentagon calls a "milestone," any sober analyst should call a desperate, expensive distraction. The LOCUST (Low-Cost UAV Swarming Technology) system is a mechanical band-aid on a gaping chest wound. While the EurAsian Times and other outlets parrot the PR scripts about "unlimited magazines" and "pennies per shot," they ignore the brutal physics and the even more brutal economics of modern attrition.
The U.S. Navy is bringing a scalpel to a sledgehammer fight. For another perspective on this event, see the latest update from ZDNet.
The Mirage of the Low-Cost Shot
The most seductive argument for DEW is the cost-per-kill. Military contractors love to brag that a laser shot costs $1 or $10, compared to a $2 million RIM-162 Evolved SeaSparrow Missile (ESSM). It sounds like a financial masterstroke.
It isn't.
This logic ignores the Total System Cost of Engagement. To fire that "one-dollar shot," you need a multi-million dollar beam director, sophisticated cooling systems that eat up deck space, and a massive power generation suite. You aren't just paying for the electricity; you are paying for the integration of a fragile, sensitive optical instrument onto a platform designed to withstand shockwaves, salt spray, and massive vibrations.
When a $2,000 drone from a garage in Tehran or a factory in Shenzhen flies toward a billion-dollar destroyer, the "cost per shot" is a rounding error. The real metric is Reliable Interception Rate under Saturation.
The LOCUST system, like most current solid-state lasers, struggles with atmospheric dwell time. You don't just "hit" a target with a laser and it explodes like a Michael Bay movie. You have to dwell on a specific point of the airframe for several seconds to burn through the casing or fry the sensors.
Imagine a swarm of 50 drones. While your LOCUST system is busy "dwelling" on Drone A for five seconds, Drones B through Z are already inside your defensive perimeter. Lasers are serial killers in a world that requires parallel processing.
Physics Does Not Care About Your Press Release
The "lazy consensus" suggests that lasers are the ultimate weapon because light travels at $c$. Speed is irrelevant if the medium is hostile.
The ocean is the worst possible environment for a laser. You have:
- Particulate Scattering: Salt spray and humidity scatter the beam.
- Thermal Blooming: The laser heats the air it’s passing through, which then acts as a lens and defocuses the beam.
- Aerosol Absorption: Smoke, fog, or even simple clouds turn your "milestone" weapon into an expensive glow-stick.
If I am an adversary, I don't need a "stealth" drone to beat the USS George H.W. Bush. I just need to wait for a foggy morning or deploy a simple, cheap smoke screen. Or, even simpler, I coat my drones in a reflective or ablative material.
If your "drone-killer" can be defeated by a $50 bucket of high-heat reflective paint or a literal cloud, you don't have a weapon. You have a laboratory experiment that escaped into the fleet.
The Power Paradox
Let’s talk about the math they won't put in the brochure. To produce a laser beam with enough intensity to melt high-grade composites or aluminum at a distance of several kilometers, you need massive amounts of energy.
$$P_{target} = P_{source} \cdot e^{-\sigma R}$$
Where $P$ is power, $\sigma$ is the atmospheric extinction coefficient, and $R$ is range. As $R$ increases, your power at the target drops exponentially. To compensate, ship designers have to divert power from other critical systems—propulsion, radar, or electronic warfare suites.
Most current U.S. destroyers are already "power-dense." They don't have the spare megawatts lying around to run a continuous-wave laser during a sustained engagement. We are building ships that have to choose between moving and shooting.
I’ve seen the internal specs on these "successful" tests. They often occur under "Goldilocks" conditions: clear skies, low humidity, and a cooperative target flying a predictable profile. In the Red Sea or the South China Sea, those conditions don't exist.
The Swarm is Smarter Than the Beam
The Navy’s fascination with LOCUST ignores the fundamental shift in drone warfare: autonomy.
The current "counter-UAS" philosophy assumes we are shooting at remote-controlled toys. We aren't. We are moving toward AI-driven swarms that communicate and adjust their vectors in real-time.
If a swarm detects a high-energy laser engagement, the drones can simply oscillate their flight paths. By slightly rotating or wobbling, the drone prevents the laser from dwelling on a single spot long enough to cause structural failure. This "wobble" costs the drone nothing. It costs the Navy the ship.
Furthermore, the LOCUST system is a line-of-sight weapon. It cannot hit what it cannot see. Cheap drones can skim the waves (sea-skimmers) or use terrain masking. By the time a deck-mounted laser has a clear line of sight, the kinetic impact is seconds away.
The Institutional Sunk Cost
Why is the Navy pushing this narrative so hard? Because they’ve spent decades and billions of dollars on Directed Energy, and they have nothing else to show for it.
The railgun is dead. The Zumwalt-class is a floating cautionary tale. The Navy is desperate for a win, so they take a system that can burn a hole in a stationary plastic drone and call it a "major milestone."
It’s a classic case of Technology Fetishism. We are obsessed with the "cool" factor of lasers while ignoring the "boring" effectiveness of high-capacity kinetic interceptors or advanced Electronic Warfare (EW).
An EW suite can drop an entire swarm by severing their data links or spoofing their GPS for a fraction of the power and complexity of a laser. But EW isn't "visual." It doesn't look good in a recruitment video. A laser beam (even an invisible one represented by an artist's rendition) sells better to Congress.
The Actionable Reality
If we want to actually protect a carrier strike group, we need to stop chasing the "Star Wars" fantasy and look at Asymmetric Defense Integration.
- Mass-Produced Kinetic Interceptors: We need missiles that cost $20,000, not $2,000,000. Use existing "dumb" rocket technology with basic seeker heads.
- Hardened EW Bubbles: Instead of trying to melt one drone at a time, we should be focused on microwave technology (HPM) that fries the circuits of every drone in a 30-degree cone.
- Ablative Doctrine: Accept that some drones will hit. We need to build ships that are compartmentalized and "tough" rather than "exquisite" and fragile.
The LOCUST test on the USS George H.W. Bush wasn't a glimpse of the future. It was the final gasp of a 20th-century mindset trying to solve a 21st-century problem with a flashlight.
The drone swarm isn't afraid of your laser. It's waiting for it to get cloudy.
Stop celebrating milestones that are actually tombstones for tactical reality.
Naval supremacy is currently a paper tiger, and all the lasers in the world won't keep it from burning when the real swarm arrives.
