WEST PALM BEACH, Florida, May 27, 2026 (GLOBE NEWSWIRE) -- Quantum Cyber N.V. (Nasdaq: QUCY) (“Quantum Cyber” or the “Company”), a Nasdaq-listed autonomous defense technology company assembling an AI-powered System-of-Systems platform for drone warfare, counter-UAS, and border security applications, today announced the filing of a provisional patent application with the United States Patent and Trademark Office covering a Coaxial Dual-Propellant Grain Solid Rocket Motor (the “CDPG-SRM”) engineered to extend the operational range and mission endurance of unmanned aerial vehicles across defense, border security, and autonomous warfare applications.
A Structural Shift in U.S. Defense Procurement -- and Where the CDPG-SRM Fits
The commercial significance of this filing is notable as U.S. defense procurement is undergoing a shift toward low-cost, long-range autonomous systems deployed at scale -- and range extension through propulsion is one of the documented bottlenecks limiting that transition.
Executive Order 14307 establishes American drone dominance as an explicit industrial and national-security priority, directing the acceleration of domestic drone production, expanded exports of U.S.-made systems, and the enablement of more advanced autonomous operations. Concurrently, the Department of Defense's (the “DoD”) budget for the 2027 fiscal year proposes an estimated $54 billion to $75 billion in allocations toward drones, autonomous warfare, and counter-UAS systems -- a commitment that reflects a fundamental change in how the Pentagon intends to fight.
Central to that doctrine is the concept of "attritable" drones: inexpensive, expendable autonomous platforms deployable in mass rather than in limited numbers. DoD programs including Replicator and the Defense Autonomous Warfare Group are operationalizing this model. Operational experience from Ukraine and Indo-Pacific planning has reinforced the same lesson: militaries that can field large numbers of long-range, modular autonomous systems at low cost hold a decisive asymmetric advantage.
Propulsion is the constraint. Small UAVs in the 1-15 kg class are limited in range and loiter time by their primary propulsion systems. Boost-assist rocket motors offer a modular path to extended performance without redesigning the underlying airframe -- a critical advantage for a defense industrial base increasingly focused on rapid fielding and cost discipline.
Boost-Sustain Architecture for Extended Drone Operations
The CDPG-SRM employs a coaxial architecture placing a high-thrust boost grain concentrically around a lower-thrust sustain grain, separated by a proprietary thermal barrier interlayer and transition charge. The design delivers a two-phase thrust profile: an initial boost phase of approximately 3-8 seconds at peak thrust, followed by a sustain phase of 15-45 seconds at reduced thrust, with a boost-to-sustain thrust ratio of 3:1 to 8:1. The motor is scalable across outer casing diameters of 30-100mm and integrates with UAV airframes in the 1-15 kg class via a detachable cradle and release latch mechanism, enabling clean jettison following burn completion.
The nozzle assembly incorporates a high-density graphite throat insert rated for pressures of 3.5-5.5 MPa and temperatures exceeding 3,000 K, backed by an ablative phenolic sleeve. The thermal barrier interlayer -- composed of silica microspheres in an HTPB matrix with alumina and ceramic fillers -- maintains thermal conductivity below 0.4 W/(m*K), enabling sequential ignition of the two propellant zones while maintaining structural integrity throughout the burn sequence.
Strategic Positioning Within the Quantum Cyber System-of-Systems Platform
The CDPG-SRM is designed as the propulsion layer of Quantum Cyber's emerging multi-domain technology portfolio. The Company's System-of-Systems platform currently spans drone warfare, counter-UAS, autonomous naval mine countermeasures, EMP shielding, anti-drone ammunition, and command-and-control -- covering air, land, and sea engagement tiers. Propulsion IP of this nature is directly additive to that portfolio, and the Company believes it increases the strategic value of potential partnerships with UAV original equipment manufacturers and positions the Company as a meaningful participant in the domestic drone supply chain that U.S. policy is now aggressively building.
