1. What is Leonidas?
- Leonidas is a high-power microwave (HPM) weapon developed by Epirus for the U.S. military.
- Its main function is to disable drones by emitting a powerful electromagnetic pulse (EMP).
- The weapon can neutralize dozens of drones simultaneously—in recent tests, it took down 49 drones in a single pulse.
2. How it Works
- Traditional drone defenses use missiles or guns to destroy drones individually, which is expensive and slow.
- Leonidas instead uses directed electromagnetic energy to fry the electronics of drones in a targeted area.
- The system is truck-mounted, making it mobile and rapidly deployable, unlike older fixed installations.
3. Technology Behind It
- The breakthrough is gallium nitride (GaN) semiconductors:
- Replaces bulky vacuum tubes used in older systems.
- Allows for compact, solid-state electronics that can fit on a pickup truck.
- Reduces the need for large cooling systems and permanent infrastructure.
- Software-defined waveforms allow operators to adjust electromagnetic effects in real-time.
- This helps neutralize drones while minimizing collateral damage to friendly electronics nearby.
4. Cost Efficiency
- One of Leonidas’s biggest advantages is its low cost per target:
- Traditional interceptor missiles cost $2 million per shot.
- Leonidas can neutralize drones for pennies per kill, as long as electricity is available.
- This makes it extremely cost-effective, especially against low-cost hobby drones that can still shut down airports or threaten critical infrastructure.
5. Real-World Applications
- Designed to protect:
- Airports from rogue drones.
- Military bases and critical infrastructure.
- Convoys or field operations in areas with drone threats.
- Can be used wherever drone swarms threaten security assets.
6. Limitations
- Requires substantial power generation, specific numbers are classified.
- Range is limited, and nearby electronics could experience collateral electromagnetic effects.
- Operators must carefully configure exclusion zones to avoid disrupting friendly electronics.
7. Why It Matters
- AI-driven drone swarms are becoming a serious threat: multiple drones can coordinate attacks faster than humans can respond.
- Traditional missile-based defenses cannot keep up due to cost and speed limitations.
- Leonidas offers a scalable, mobile, and economical solution to counter swarms.
