Defiant H4 Arcana

Defiant H4 Arcana is a reconnaissance UAV equipped with a highly efficient 4-stroke gasoline engine from the Japanese company OS Engines (GF40), delivering a flight range of up to 1,200 km.

The airframe consists of a lightweight and durable carbon fiber tube housing a flexible fuel tank, paired with aluminum wings manufactured by a robotic welding system.

This manufacturing technology enables the production of several thousand units monthly. The drone features a 3,600 mm wingspan, a length of 2,600 mm, and a maximum takeoff weight (MTOW) of 65 kg. It is powered by an efficient German 3W-157Xi B2 TS CS gasoline engine generating 18.5 hp, providing an endurance of up to 8.5 hours. Its cruising speed is 130 km/h, with a service ceiling of 4,000 m.

Equipped with an 8-channel anti-jamming/anti-spoofing CRPA antenna and satellite receiver, integrated with an Inertial Navigation System (INS) and AI-based visual navigation, the drone is fully capable of operating in dense Electronic Warfare (EW) environments and complete GNSS-denied conditions. It achieves high precision with a Circular Error Probable (CEP) of under 15 m. Featuring an onboard Starlink terminal and an AI-driven flight control system configuration, the loitering munition can autonomously identify and engage targets. Launch is executed via a rocket booster (RATO) or mid-air release from a hexacopter. Removable wings allow for convenient transport in standard cargo trucks.

1. Key Features & Capabilities:
   1. Automatic Target Recognition (ATR) and autonomous homing driven by Artificial Intelligence.
   2. 8-channel CRPA antenna with spoofing- and jamming-resistant satellite signal reception.
   3. Redundant visual and inertial navigation systems tailored for operations in GPS/GNSS-
   denied environments.
   4. Man-in-the-Loop control and post-launch retargeting via the Starlink system.
   5. Seamless integration with existing C2, targeting, and fire control systems (ATAK, Next Gen C2, etc.).
   6. Open architecture supporting future integration of third-party payloads and software.
   7. NDAA compliant with a resilient US and allied supply chain.
   8. Zero launch infrastructure footprint. Launched via rocket booster or covertly dropped from a
   hexacopter. Optional parachute recovery system for reusable deployments.
   9. Low operational cost requiring minimal additional expenditure for infrastructure, training, or maintenance.
   10. Containerized storage capabilities (detachable wings) and ruggedized performance for long-term deployment in harsh field environments, including dust, moisture, precipitation, and extreme temperatures.

The cost of flight-ready Defiant rockets and UAVs includes advanced electronic warfare-resistant military navigation and communication systems, AI-driven guidance systems, and comprehensive operator training. Additional charges apply for the ground control station, CRPA system (8, 12, or 16 channels), and munitions.
