Lirith designs and manufactures NDAA-compliant electronic speed controllers for US drone programs — engineered for defense environments, documented for procurement, and produced in the United States.
The United States has spent a decade watching adversaries dominate small-unmanned-systems manufacturing. The NDAA and the American Security Drone Act have drawn a clear line: federal agencies cannot operate drones built with covered foreign components. That requirement has reshaped every bill of materials in the industry.
Flight controllers, radios, and GPS modules now have credible American alternatives. The electronic speed controller does not. Nearly every ESC in commercial and military drones ships from Chinese factories, and every US drone OEM building for defense is scrambling to source a replacement that meets compliance and production-volume requirements.
Lirith was founded to close that gap — with ESCs designed, sourced, and manufactured in the United States, engineered to the reliability standards defense programs actually demand.
Every component source documented, audited, and verified against NDAA and ASDA requirements. We provide full bills of material, certificates of conformity, and supply-chain traceability statements to every customer — the same package DoD primes ask for, ready from day one.
Standard 30.5 mm mounting, machine-mountable pad-stack, consistent part sourcing across production runs, and a supply guarantee that lets our customers ship roadmaps without holding their breath. We ramp with you.
Conformal coating, wide-temperature components, rigorous thermal design, and vibration tolerance as standard. Not an FPV board with a defense sticker — an ESC engineered from a blank sheet for the environments and missions it needs to survive.
Direct engineering support, open integration documentation for ArduPilot and PX4, and responsive customer service from the team that actually designed the product. No outsourced support tiers, no black-box firmware.
Appropriated by Congress for expanding the US sUAS industrial base.
Requested for US Army small unmanned aerial systems programs.
Small drones being acquired at under $4K per unit by the US Marine Corps.
Effective date for the American Security Drone Act ban on covered UAS.
Lirith is building for a real, funded, urgent market. The drones the US military buys in the next five years will be built by American companies with American components. We're here to make the ESC one of them.
