Native Parallel Architecture
Electric and combustion, working together or alone. Instant switching or combined power for any mission profile.
World’s FirstNative Parallel Hybrid™Propulsion
A drop-in propulsion system delivering stealth, endurance, and reliability - purpose-built for tactical UAVs and loitering munitions.
- 5× Endurance
- Silent Flight Mode
- Drop-In Integration
Your Mission Shouldn’t End with Your Battery
Electric UAVs run out mid-mission. Combustion engines are loud, heavy, and compromise stealth. And most “hybrids” are just add-ons that don’t deliver.
When your engine quits, the mission fails.
In our world, failure isn’t an option.
What Is Native Parallel Hybrid™
Native Parallel Hybrid™ is the only propulsion architecture built from the ground up to combine electric stealth and combustion stamina on the same drivetrain - allowing either to operate independently or together.
Unlike “hybrid” retrofits, Native Parallel Hybrid™ is engineered hybrid from its first blueprint to deliver seamless power transitions, maximize endurance, and maintain full operational flexibility without redesigns or compromises.
- 5× Endurance
- Silent Flight Mode
- Drop-In Integration
The LH Advantage
Four core differentiators that make LH the only choice for mission-critical UAV propulsion.
Endurance + Stealth in One System
Silent electric mode when stealth matters. Fuel-powered range when time does. Switch mid-flight. Recharge batteries on the go.
Drop-In Tactical Integration
No full-system overhaul. Our Native Parallel Hybrid™ system allows for efficient conversion of existing electric group 2 or 3 UAVs, requiring only minor adaptations for fuel integration. Plug in, power up, and fly with extended capabilities.
Flight-Proven
Field-tested. Defense-integrated. Not either-or. And not optional.
A New Standard in Tactical Performance
5× Endurance
Extended mission duration beyond battery limitations.
Silent Mode Operations
Covert ISR and tactical loitering capabilities.
In-Flight Battery Charging
Removes range anxiety during missions.
Dual Power Redundancy
Automatic failover and limp-home capabilities.
High W/kg Performance
Optimized power-to-weight for tactical operations.
Boosted Power at Takeoff
Full torque when you need it most.
Others Sell Components. We Engineer Power.
While competitors offer bolt-on solutions or complete UAVs, LH provides the only true drop-in hybrid propulsion system for tactical operations.
