Citadel
Multi-Domain Counter-UAS & ATGM Defense System
Citadel is a cutting-edge counter UAS system designed to provide advanced protection against hostile air attacks . With its state-of-the-art Counter-UAS and ATGM interception capabilities, Citadel ensures a reliable, scalable solution for force & point protection.
System Components




Hive
Hive is Tehiru’s integrated interceptor management and deployment system, designed to store, sustain, and launch interceptors directly from mobile platforms across land, air, and sea domains.
Each Hive unit houses four interceptors organized into two independent magazines, enabling controlled, sequential, or rapid deployment based on mission demand.
Hive manages interceptor energy lifecycle, including charging, health monitoring, and readiness optimization, ensuring each unit remains mission-ready without manual intervention.
The system governs launch sequencing and deployment logic, enabling fast, reliable, and coordinated release from the host platform while maintaining synchronization with SharkOS engagement management.
Deployed on ground vehicles, aerial carriers, or maritime vessels, Hive transforms host platforms into sustained C-UAS defense nodes capable of rapid response and continuous protection.




Magazine
A compact, swappable magazine designed to store, protect, and interface with two interceptor drones.
The system supports five magazines total: two magazines installed inside the Hives (four drones ready for launch) and three additional magazines stored and charged in a docking station for rapid reload and sustained operations.



Cipher
Cipher is a modular interceptor drone blueprint designed for integration within the Hive platform and purpose-built for CUAS Category 1–3 missions.
As a hardware system, Cipher provides the airframe, payload interfaces, and onboard compute required to support SharkOS for mission execution and control.
Cipher includes SwiftlinkOS-ready communications hardware, enabling fully encrypted connectivity over RF or fiber-optic links in contested environments.
All Cipher hardware components are NDAA-compliant, and final assembly is performed in the United States.
Rather than a single fixed configuration, Cipher is delivered in multiple variants tailored to customer requirements, with configurable payloads, endurance profiles, and performance characteristics




Platform Integration
The Citadel Interception System is a multi-platform solution, deploying across air, land, and sea to deliver flexible CUAS protection wherever operational coverage is required.
On land, the system installs on a range of vehicles to support convoy protection and mobile or fixed-site aerial defense. Detection systems may be installed on the host vehicle by Tehiru partners or existing customer-designated providers, enabling seamless alignment with current sensor architectures.
In the air, interceptors deploy from carrier aircraft capable of transporting multiple units and sustaining extended airborne operations, enabling rapid reinforcement and reduced turnaround time.
At sea, the system deploys on naval vessels to protect maritime convoys and high-value assets, including large surface combatants and aircraft carriers.
Tehiru is also advancing future space-based deployment concepts, positioning interceptors for operation from satellite platforms.
SharkOS
SharkOS is Tehiru’s distributed engagement and fire-control operating system powering the Citadel CUAS stack. Operating directly on each interceptor, SharkOS enables localized guidance, intercept execution, and terminal engagement logic at the edge.
This distributed architecture supports scalable defense against multiple simultaneous aerial threats. Each interceptor executes mission logic independently, while a ground-based scheduling layer manages tasking, prioritization, and resource allocation across the engagement envelope—minimizing operator burden and compressing time-to-effect.
SharkOS is designed in alignment with modular open systems principles, interfacing with third-party or government-provided detection systems through defined target-state and performance requirements. Tehiru does not replace existing command, detection, or frontend systems; instead, SharkOS enhances current operational architectures by integrating into established sensor and battle management ecosystems.
When paired with SwiftlinkOS, SharkOS operates over fully encrypted, resilient communication pathways, supporting coordinated engagement in contested or degraded environments.
