The small unmanned aircraft threat that has pervaded the battlefield has also moved far beyond it. From critical infrastructure attacks to cartel surveillance of border patrol agents, adversarial small UAS (sUAS) now present a persistent challenge to first responders and law enforcement as well as military personnel operating in complex, dynamic environments. Black River Systems Company™, headquartered in Utica, New York, has spent nearly a decade engineering a direct answer to that problem. The company built its Ninja™ family of counter-sUAS (C-sUAS) systems from the ground up to be portable and protocol-intelligent across nearly any platform. Its most recent additions to that family, the Ninja Dismount™ and the Ninja Shield+™, have evolved that C-sUAS capability in terms of packaging and deployment. While systems share the same core Ninja detection and defeat architecture, Black River has purpose-engineered each for distinct operational demands.
What is Ninja?
Black River Systems Company, headquartered in Utica, New York, has spent nearly a decade engineering a direct answer to the problem posed by sUAS with its Ninja family of C-sUAS systems. Ninja scans across the frequency ranges that drones operate in. It employs advanced Direction Finding and Machine Learning algorithms which add a layer of adaptive intelligence that static signature libraries cannot provide. Ninja detects more than 300 drone signatures, including Remote ID and its detect and defeat capabilities are more than just library based. Ninja is software-upgradeable, meaning new capabilities are developed with the intention to use hardware already in the field.

Protocol-based intelligence separates Ninja from conventional jamming solutions. Rather than broadcasting indiscriminate RF energy that can disrupt friendly communications, the system inherently understands the exact signaling and protocols used by adversarial UAS. Operators receive precise sUAS location, drone identification and drone’s controller location data, with zero false alarms. The system supports multiple operational modes, including RF takeover and jamming. Users can configure it for autonomous operations for compressed human decision loop timelines.
Black River prioritized command-and-control (C2) flexibility and supports integration with FAADC2, MEDUSA, EBRISS, ATAK and UC2 C2 platforms. This enables it to fit into existing government and military command architectures without requiring operators to learn new systems. Operators can run the system from a laptop, tablet or phone using the Ninja web display or ATAK interface. Multiple networked Ninja systems share a common C2 picture, providing a networked web of sensors for a more complete sUAS domain awareness.
Ninja Shield+: Unit Level Expeditionary Force Protection
The Ninja Shield+ targets expeditionary force protection at the team and unit level. At 21 pounds, the Shield+ remains light enough for a single person to carry it in a backpack but still powerful enough to serve as a fixed-site, vehicle-mounted or airborne C-sUAS solution. A single operator can have it fully deployed in five minutes.
The Shield+ scans across a frequency range of 70 MHz to 6 GHz. It detects more than 300 drone signatures, including Remote ID. It employs advanced Direction Finding and Machine Learning algorithms which add a layer of adaptive intelligence that static signature libraries cannot provide, to identify never-before-seen signals. Its integrated High Power Amplifier enables denial defeats.
Ninja Dismount: Individual Carry C-sUAS for Dismounted Ops
The Ninja Dismount is optimized for an individual to carry. This makes it practical for military, law enforcement officers, or emergency responders who need mobile CUAS capabilities not constrained to a fixed station.

It weighs just 4.5 pounds when equipped with antennas, battery and network cable. This lightweight package, however, delivers full 360-degree protection against most commercial sUAS and requires no active pointing. This makes it practical for patrol officers, military dismounts and emergency responders who cannot afford to be anchored to a fixed station.
Protocol-based intelligence separates the Ninja Dismount from conventional jamming solutions. Rather than broadcasting indiscriminate RF energy that can disrupt friendly communications, the system inherently understands the exact signaling and protocols used by adversarial UAS. Operators receive precise sUAS location, drone identification and controller location data, with zero false alarms. The system supports multiple operational modes, including RF takeover and jamming. Users can configure it for autonomous operations for compressed human decision loop timelines.
The Dismount interfaces with both the Android Team Awareness Kit (ATAK) and a web-based Graphical User Interface (GUI). This provides operators with familiar command-and-control (C2) displays. It runs on a PRC-148/152 compatible battery with more than eight hours of single-battery runtime. It also carries an IP67 environmental rating and operates across temperature extremes from -40 degrees Celsius to 65 degrees Celsius. These specifications make it suitable for deployment in extreme environments that span the Arctic to the desert Southwest.
Mounting versatility defines Dismount’s design philosophy. The system supports low-profile Modular Lightweight Load-carrying Equipment (MOLLE) mount brackets with quick-release functionality, MOLLE holsters with adjustable BOA lacing and the industry-standard AMPS four-hole attachment pattern compatible with mounting solutions from manufacturers such as RAM, Bullet and Gamber Johnson. A magnetic vehicle roof mount enables rapid mobile deployment on standard and non-ferrous vehicle platforms. A standard pole mount kit accommodates poles up to three inches in diameter. In practice, that range of mounting configurations means a single Dismount unit can transition from a soldier’s or responder’s vest to a vehicle roof to a pole-mounted fixed position within the same mission.
Ninja on Quad-UGVs Provides C-sUAS Capability on Four Legs
Ninja C-sUAS capabilities can integrate onto Boston Dynamics’ Spot quadruped uncrewed ground vehicle (Quad-UGV) robot, or “drone dog.” The Ninja Dismount’s AMPS-compatible mounting system and configurable autonomous operations mode make it a natural payload candidate for Spot and other robotic platforms operating in environments too dangerous or inaccessible for human operators.
Spot has already demonstrated its utility across hazardous inspection, reconnaissance and security missions for military and first responder users. Pairing the robot with a Ninja payload adds active C-sUAS protection to those missions. For example, it allows Spot to detect and defeat adversarial drones while conducting perimeter patrol or route clearance operations.
“The convergence of autonomous ground platforms and C-sUAS technology was always a logical next step,” noted Dr. Brandy Hill, Customer Relationship and Marketing Manager for C-UAS at Black River Systems. “Operators in the field needed a way to extend drone protection beyond the range of a single person. Putting Ninja on a platform like Spot does exactly that.”
Multiple Ninja Dismount units can also intelligently collaborate in defeating sUAS and share a common C2 picture across a networked deployment. This allows for a coordinated robotic C-sUAS response across a large area without continuous human supervision.
Remote Ninja Ops Via Mesh Networks and MANET Radios
Integrating Ninja payloads onto mobile and robotic platforms raises a critical question of connectivity. Exactly how does a Ninja unit mounted on a robot dog or a vehicle relay its detection picture back to a human operator, and how does an operator issue defeat commands when the platform is operating beyond line of sight? Persistent Systems’ Mobile Ad hoc Networking (MANET) radio technology.

Persistent Systems’ radios create resilient, self-forming mesh networks that maintain connectivity between dismounted soldiers, vehicles, aircraft and robotic platforms across GPS-denied and RF-congested environments. The Ninja system’s Ethernet connectivity and ATAK integration align directly with Persistent Systems’ network architecture. This allows Ninja detection data and defeat commands to flow across a MANET node as part of a unified tactical network.
This combination enables scenarios where a Spot robot carrying a Ninja Dismount conducts autonomous perimeter patrol, streams its C-sUAS sensor picture back through a Persistent Systems radio mesh to a human operator at a command post, and executes defeat actions on command…all without requiring the operator to be physically collocated with the threat environment.
“When you can put a Ninja on a robotic asset and control it through a Persistent Systems mesh, you have removed the operator from harm’s way while maintaining full C-sUAS authority,” Dr. Hill explained. “That combination of protocol-based intelligence and networked autonomy is exactly what first responders and defense units have been asking for.”
The Ninja Ecosystem: Scalable, Software-Upgradeable C-sUAS
Black River has been the lead developer and Original Equipment Manufacturer (OEM) of the Ninja C-sUAS product family since 2016. It matured the original system from concept to Initial Operational Capability (IOC) in eight months and delivered the improved Ninja Gen2 system just ten months after that. That development pace reflects a deliberate design choice. By keeping Ninja software-upgradeable, hardware already in the field can defeat threats that did not exist at the time of purchase.
Every Ninja system, from the Dismount to the Shield+, shares a common C2 picture and meshes seamlessly with other Ninja units in the field. That interoperability means a first responder with a Dismount on their MOLLE vest can contribute to the same sensor picture as a Shield+ unit mounted on a nearby command vehicle or a Ninja payload operating on a Spot robot 500 meters away. A layered, distributed C-sUAS architecture results. It scales from individual operator protection to wide-area force protection, all built on American-made hardware with full lifecycle support.
“Our goal from the beginning has been to make sure no operator, whether they are a police officer at a public event or a soldier at a forward operating base, ever faces a drone threat they are not equipped to handle,” Dr. Hill added. “Ninja was built to grow with the threat. These new integrations show how far that vision has come.”
Black River Systems designs and manufactures its Ninja products entirely within the United States, with full lifecycle support for all fielded systems. In a threat environment where adversarial drones are no longer a battlefield-only concern, the Ninja family’s portable, software-upgradeable architecture offers operators a single system family that scales from a patrol officer’s vest to a robotic platform without changing the underlying technology.
