Find out more about directed-energy weapon technologies, such as lasers and railguns, and their future potential in combat aircraft.

Directed energy weapons

Directed energy weapons (DEW) represent a significant advance in the military field, offering unique and revolutionary capabilities. Among the most promising AED technologies are lasers and railguns, whose integration into combat aircraft could transform the dynamics of aerial confrontations. This article takes an in-depth look at these technologies, their advantages, disadvantages and future implications.

Laser technology

High-Energy Lasers (HEL) use a concentrated beam of light to damage or destroy targets. Operating at powers ranging from several kilowatts to megawatts, these systems can target with precision and at high speed.

Case in point: The US Navy’s AN/SEQ-3 Laser Weapon System (LaWS) uses a 30 kW fiber laser, capable of destroying drones and neutralizing short-range threats.

Benefits:

1. High precision: Lasers can target with millimetre-level accuracy.
2. Speed of light: The laser beam reaches its target almost instantaneously, reducing the chances of escape.
3. Infinite ammunition: As long as energy is available, the laser can fire indefinitely.

Disadvantages:

1. Atmosphere: Laser effectiveness can be reduced by rain, dust or smoke.
2. Thermal dissipation: Laser systems generate a lot of heat, requiring advanced cooling systems.
3. Power requirements: High-energy lasers require considerable power sources, which may limit their deployment on certain platforms.

Railgun technology

Railguns use electromagnetic fields to fire projectiles at very high speeds, surpassing traditional weapons in terms of range and power.

**The US Navy’s prototype railgun can fire projectiles at a speed of 2.5 km/s, with an effective range of 160 km.

Benefits:

1. Speed and range: Projectiles reach hypersonic speeds, offering superior range and penetration.
2. Kinetic impact: Projectiles do not require explosives; kinetic energy is sufficient to cause significant damage.
3. Cost per shot: Once the system is in place, the cost per shot is lower than that of traditional missiles.

Disadvantages:

1. Rail wear: Electromagnetic forces cause rapid rail wear, requiring frequent maintenance.
2. Energy required: Like lasers, railguns require significant amounts of energy.
3. Volume and weight: Railgun components can be bulky and heavy, posing integration challenges for aircraft.

Potential benefits of EDAs in combat aircraft

Cost reduction: The absence of conventional ammunition can reduce logistics and procurement costs.

Increased endurance: Combat aircraft equipped with AEDs can engage multiple targets without fear of running out of ammunition.

Improved versatility: EDAs can be used for a variety of missions, from missile defense to ground target destruction.

Consequences of integrating EDAs

Changing military strategies: The introduction of EDAs in combat aircraft could change the way air operations are planned and executed. Long-range attacks and rapid engagements would become more common.

Increased technological development: The integration of EDAs requires advances in power management systems, heat-resistant materials, and targeting software.

Regulatory and ethical issues: The use of EDAs raises questions about rules of engagement and the impact on civilians, requiring a clear regulatory framework.

Directed energy weapons, notably lasers and railguns, represent a significant advance for combat aircraft. Their ability to deliver instantaneous, precise firepower, combined with virtually unlimited endurance, offers undeniable strategic advantages. However, the technical and logistical challenges associated with their deployment must be overcome to realize their full potential. As technologies progress, it is likely that EDAs will play an increasingly important role in the armed forces of the future.
