This project develops, matures, and demonstrates novel capabilities that aid in the detection, tracking, identification, mitigation, and/or defeat of small unmanned aerial systems (sUAS) groups 1-3. Matures, demonstrates, and transitions interceptor capabilities to deliver physical effects that enable faster intercept, greater standoff ranges, increased magazine depth, survivability, affordability, and/or decrease in size, weight, and power requirements. Develops capabilities to track and predict UAS flight paths, airspace situational awareness, and/or location of UAS operators to increase defeat and force protection capabilities. Matures and demonstrates algorithms to enable threat prioritization, airspace control, coordinated response, and resource management of CsUAS capabilities. Matures technical solutions to defeat sUAS capabilities, including target acquisition, navigation, and control, in addition to identifying and exploiting weaknesses in sUAS system design and operation. Matures concepts and designs essential for soldier-common C-sUAS integrated capabilities to impair sUAS detect and attack, provide early warning, and increase individual and position protection for soldiers and small units. Work in this project is performed by the Aviation & Missile Center (AvMC), Armaments Center (AC), Ground Vehicle Systems Center (GVSC), Soldier Center (SC), Command, Control, Computers, Communications, Cyber, Intelligence, Surveillance and Reconnaissance (C5ISR) Center and Space and Missile Defense Command.

Counter Swarm Kinetic Integrated Defeat▼ 7%
FY2025 actual
FY2026 enacted$2.6M

FY2027 planned work Will mature and demonstrate capabilities with more dynamic counter swarm behaviors with hardware; exploit previous analyses to demonstrate counter swarm capabilities working with weapon/munition in a layered defense.

FY2026 to FY2027 change Funding decrease is an economic adjustment.

FY2026 plans — current year Will exploit results from small, medium, and large caliber weapon and ammunition analyses to mature solutions for counter- swarming (C-Swarm), incorporating improvements to kinetic weapon/munition systems; improve targeting and countermeasure performance for networked weapon/munition and fire control systems.

FY2026 to FY2027 change Funding decrease reflects realignment within this project to C-sUAS Deny and Defeat Adv Tech.

FY2026 plans — current year Will mature concepts, designs, and initial component technologies and subsystems essential to XRC missile prototypes required capabilities; design and development of prototypes include airframe, propulsion, seeker, guidance and control components based on feedback from initial prototype designs; mature government six-degree of freedom model development; incorporate industry partner(s) designs into six-degree of freedom modeling and simulation capability and begin assessment of industry partner(s) subcomponents in government hardware-in-the-loop testing as available.

Program detail

Mission & acquisition strategy

This Program Element (PE) develops, matures, and demonstrates novel capabilities that aid in the detection, tracking, identification, mitigation, and/or defeat of small unmanned aerial systems (sUAS) groups 1-3. Develops and matures counter-small UAS (C-SUAS) detection capabilities in radar, radio frequency (RF), electro-optical and infrared (EO/IR), and acoustic signature regimes. Develops capabilities to track and predict UAS flight paths, airspace situational awareness, and/or location of UAS operators to increase defeat and force protection capabilities. Matures identification methods to discern aerial systems and payloads.
