• The US Army is negotiating a contract with AeroVironment for the Enduring High-Energy Laser (E-HEL).
• The E-HEL system is expected to cost between $400 million and $500 million.
• The system will engage Group 1 through Group 3 unmanned aircraft.
• AeroVironment's LOCUST X3 has a per-engagement cost under $5.

The Army's investment in E-HEL may indicate a shift towards directed-energy defense against drones, which could significantly reduce costs per engagement and enhance counter-drone capabilities. This development suggests the Army is moving towards a more permanent and standardized solution for high-energy laser systems, which could have broader implications for the military's approach to drone defense.
