Introduction
The famous claim that DragonFire can fire for “less than £10 per shot” is real, but it describes only a very specific part of the weapon’s economics. The figure refers primarily to the electrical energy consumed during a firing event, not to the cost of buying, integrating, maintaining, crewing, cooling, upgrading, or supporting the system throughout its service life. UK defence officials have compared a DragonFire engagement to running a household heater for about an hour, emphasising that the number represents operating energy rather than total capability cost.

Understanding this distinction is essential when evaluating claims about directed-energy weapons. A £10 laser shot may be extraordinarily cheap compared with a missile launch, but that does not mean DragonFire itself is a £10 weapon.
Energy Cost Versus Total Ownership Cost
The Ministry of Defence has consistently described DragonFire’s firing cost as typically below £10 per shot. In official explanations, the cost is tied to electricity consumption during the engagement. A ten-second firing sequence reportedly uses energy worth roughly the same as operating a domestic electric heater for an hour. [GOV.UK]GOV.UKadvanced future military laser achieves uk firstcost alternative to certain tasks missiles currently carry out. The cost of operating the laser is typically less than £10 per shot. Drag…
That figure excludes a wide range of costs that military planners must still pay for:
- Research and development.
- Laser generation equipment.
- Precision optics and beam-control systems.
- Sensors and target-tracking hardware.
- Cooling and power-conditioning equipment.
- Ship integration and combat-system software.
- Maintenance, repairs, testing and upgrades.
- Crew training and operational support.
The distinction is similar to the difference between the cost of petrol burned during a single car journey and the total cost of owning the vehicle. The fuel expense is real, but it does not capture the purchase price, servicing, insurance, infrastructure, or depreciation.
DragonFire illustrates this gap clearly. In 2025, the UK awarded a £316 million contract to MBDA UK to deliver operational systems for Royal Navy service beginning in 2027. That procurement spending exists separately from years of earlier development and testing work.

Why Laser Shots Differ From Missile Launches
The £10 figure becomes meaningful when compared with conventional air-defence weapons.
A missile engagement consumes a physical interceptor. Once launched, that missile is gone and must be replaced from stockpiles. Depending on the system, an interceptor may cost hundreds of thousands or even more than a million pounds. Royal Navy materials have specifically contrasted DragonFire’s approximate £10 firing cost with Sea Viper missile engagements costing well over £1 million each.

A laser engagement works differently. The weapon does not expend a missile body, rocket motor, guidance package or warhead. Instead, it converts stored electrical power into a focused beam. As long as sufficient electrical power and cooling capacity are available, the system can continue engaging targets without consuming expensive interceptors. [GOV.UK]GOV.UKadvanced future military laser achieves uk firstcost alternative to certain tasks missiles currently carry out. The cost of operating the laser is typically less than £10 per shot. Drag…
This economic model is particularly attractive against:
- Small drones.
- Large drone swarms.
- Cheap one-way attack systems.
- Repeated harassment attacks intended to drain missile inventories.
In those scenarios, the military problem is often not whether a target can be destroyed, but whether the defender can afford to keep destroying large numbers of inexpensive threats. DragonFire’s low marginal firing cost is intended to address that imbalance.

What the £10 Number Leaves Out
The headline figure can create an impression that the entire engagement costs only £10. In reality, several hidden elements sit behind every shot.
Power Generation and Cooling
High-energy lasers require substantial electrical power and generate significant waste heat. Naval installations must provide power-management systems, energy storage, cooling equipment and supporting infrastructure. Analysts have noted that advanced laser systems may draw hundreds of kilowatts and that heat management becomes a major engineering challenge because laser conversion is not perfectly efficient.

Those systems continue to incur costs whether or not the laser is firing.
Sensor and Tracking Systems
The destructive beam is only one component of DragonFire. The system also depends on electro-optical sensors, tracking lasers, stabilised mounts, targeting software and fire-control equipment. Hitting a fast-moving drone requires finding, identifying, tracking and maintaining precise aim before energy can be delivered to the target. [Leonardo UK]uk.leonardo.comUKDragon Fire – Laser Directed Energy WeaponLeonardo UKDragonFire – Laser Directed Energy Weapon - Leonardo UKThe DragonFire laser directed energy weapon (LDEW) system achieved the…
The electricity consumed by the laser beam itself is only a fraction of the broader capability.
Availability and Sustainment
Military systems require spare parts, technical support, software updates, calibration and maintenance. These costs accumulate over decades of service. A laser may avoid spending missiles, but it does not eliminate sustainment expenses.
Consequently, the true cost of an operational DragonFire engagement is higher than the electricity bill alone, even though the marginal energy component remains remarkably low.
How the Headline Number Can Mislead Readers
The phrase “£10 per shot” is accurate within the narrow definition used by the Ministry of Defence. Problems arise when readers unconsciously interpret it as a complete cost figure.
Three different questions are often merged together:
- What does one additional firing event cost in electricity?
- What does it cost to operate and sustain the system over time?
- What does it cost to acquire the capability in the first place?
The £10 figure answers only the first question. It says very little about the second and almost nothing about the third. [GOV.UK]GOV.UKadvanced future military laser achieves uk firstcost alternative to certain tasks missiles currently carry out. The cost of operating the laser is typically less than £10 per shot. Drag…
This distinction matters because procurement decisions are based on lifecycle value, not just marginal firing cost. A laser can be extremely cheap to fire yet still require substantial investment to purchase, integrate and support.
At the same time, critics sometimes make the opposite mistake by dismissing the £10 figure entirely because the system itself is expensive. The low operating cost remains strategically important. If a warship faces repeated drone attacks, the difference between spending electrical power and spending missile inventories can become operationally significant even when acquisition costs are high.

The Real Meaning of the £10 Claim
The most accurate way to interpret DragonFire’s famous headline is as a marginal engagement-cost figure. Once the weapon and its supporting infrastructure already exist, firing the laser primarily consumes electricity worth roughly £10.

Drag…
That does not mean DragonFire costs £10 to own, deploy or sustain. Rather, it means that after the substantial investment required to field the system, each additional engagement can be dramatically cheaper than launching a conventional interceptor. The claim is therefore neither a myth nor a complete picture: it is a narrowly defined operating-cost statistic that highlights one of the most important economic advantages of directed-energy weapons.
