DHK2H120 Engine
DHK2H120
2-stroke, super-turbocharged compression-ignition aviation engine
The DeltaHawk DHK2H120 represents a new class of U.S.-built, heavy-fuel (Jet-A, JP-5, JP-8) propulsion systems designed for scalable unmanned operations. Purpose-built for medium-size Group 4 UAS platforms, the 80 to 120 hp class fills a critical gap in long-endurance, medium-power propulsion within the U.S. market. Designed for sustained, efficient operation, it enables extended mission duration, increased payload capability, and reliable performance for reusable unmanned systems. Leveraging a scaled architecture with significant commonality to larger DeltaHawk engines, the DHK2H120 delivers proven performance, simplified integration, and reduced lifecycle cost for advanced unmanned platforms.
