Laser Weapon Power Levels Explained, From 10 kW to 300 kW

Laser weapon power levels span roughly 10 kW to 300 kW, and the number on the brochure decides whether a beam dazzles a sensor, burns a small drone in seconds or has a chance against a cruise missile. Fielded systems today sit mostly between 20 and 60 kW, while the much-discussed 100 kW and 300 kW classes remain prototypes or goals, so the gap between marketing and reality is wide.

10-30 kW

Typical power of first-generation counter-drone lasers

50 kW

Class of DE M-SHORAD and publicly reported DragonFire

60 kW+

Navy HELIOS power, with growth to a higher level planned

300 kW

Goal class discussed for cruise-missile defense, not fielded

What laser power levels mean

A kilowatt rating describes the optical power the laser puts out, not the energy that actually reaches the target. The damage done depends on power multiplied by time, reduced by atmospheric loss and how steadily the beam stays on one spot. A 50 kW beam held for five seconds delivers about 250 kilojoules, enough to burn through the skin of a small drone, while the same beam would need much longer to degrade a hardened missile.

That is why militaries speak of dwell time. Most modern military lasers are fiber lasers that combine many modules into one beam, and power scales by adding modules, at the cost of weight, cooling and electricity.

Laser weapon power tiers from 10 kW to 300 kW

Laser power tiers and typical uses

Power class	Typical targets	Status
Under 10 kW	Sensors, cameras, small quadcopters at short range	Widely demonstrated; dazzlers and small counter-drone lasers
10-30 kW	Small and medium drones, mortars at short range	Fielded or in evaluation on trucks and vessels
50-60 kW	Larger drones, fast boats, some rockets and mortars	Prototypes and early operational trials
100 kW	Bigger drones, rockets, artillery shells, small boats	Army and Navy prototypes; limited fielding
300 kW	Cruise missiles and other hard, fast targets	Development goal; not fielded, per public sources

Power classes are approximate and based on public statements; exact outputs and engagement ranges are often not released.

Under 10 kW, lasers mostly blind or confuse optics, a mission also performed by the infrared countermeasures explained in our guide to chaff, flares and DIRCM. Between 10 and 30 kW they begin to destroy quadcopters and small fixed-wing drones. Above 50 kW the list of targets widens, and at 300 kW developers hope to defeat cruise missiles, although heat, thermal blooming and dwell time all become harder.

Which laser weapons exist today

Notable laser weapon programs

System	Country	Power class and status
DE M-SHORAD	United States (Army)	50 kW class on a Stryker; prototype vehicles fielded for evaluation
HELIOS	United States (Navy)	60 kW class with growth potential; fitted to a destroyer for trials
LOCUST X3 E-HEL	United States (Army)	About 30 kW class turret for counter-drone use
DragonFire	United Kingdom	Reported around 50 kW class; firing trials on drones and plans for Royal Navy ships later this decade
EOS Apollo	Australia (Dutch interest)	Anti-drone laser; a Dutch letter of intent has been signed
Russian and Chinese systems	Russia and China	State-media claims only; capability and power levels unverified

Status as reported in public sources; performance figures are vendor, government or state-media claims.

The Army’s DE M-SHORAD turned a Stryker into a mobile laser shooter. The UK’s DragonFire, led by MBDA and partners, has drawn attention because the Ministry of Defence says each shot costs only a few pounds, a government claim rather than an independent figure. Dutch interest in the EOS Apollo, covered in our article on the Apollo laser, shows the European market warming to the concept.

Why more power is not the whole answer

Raising output is the easy part. A 300 kW system needs roughly three times the electricity and cooling of a 100 kW one, which means a large vehicle, a ship or a fixed site. Even then, the beam must be held on one point for several seconds against a target that may be crossing at hundreds of meters per second.

The atmosphere also fights back. Rain, fog, smoke and dust scatter the beam, and intense heating of the air can defocus it. Reflective or ablative coatings can shrug off energy that would burn a plain drone. So the first operational users treat lasers as one layer in a defense, used against cheap drones, not as a replacement for interceptors.

Laser weapons vs microwaves and jammers

Lasers kill one target at a time with great precision and long range. High-power microwaves cover a cone of sky and work well against swarms but have shorter reach, a contrast described in our profile of Epirus and its Leonidas system. Jammers are cheap but fail against fiber-optic or autonomous drones. Most planners expect a mix of all three.

Editor’s read

The power numbers will keep climbing, but the practical question for buyers is cost per kill and availability, not peak kilowatts. A 30 to 60 kW laser that works reliably in most weather on cheap drones is operationally more useful today than a 300 kW concept that exists on slides. The next milestone to watch is whether the US and UK navies fit lasers as permanent ship equipment, not just trial gear.
