Unmanned systems (UxS) are changing the modern threat landscape.
Once largely associated with military operations, drones and other unmanned systems are now being used for surveillance, disruption, sabotage and attacks against critical infrastructure. They can operate across the air, land, sea and subsurface domains, giving adversaries new ways to target high-value assets while complicating traditional defence strategies.
For defence and military decision-makers, the challenge is no longer simply how to detect a drone. It is how to build a Counter-UxS capability that can identify, assess and respond to increasingly sophisticated threats across multiple environments.
The UxS threat is expanding beyond the battlefield
Recent conflicts and incidents have demonstrated how quickly unmanned technology can evolve from a tactical capability into a strategic threat.
In Ukraine, adapted Iranian-made Shahed-type loitering munitions have been used extensively against critical national infrastructure. Elsewhere in the Middle East, drone strikes targeting infrastructure have demonstrated how unmanned systems can threaten assets far beyond conventional battlefields.
The risk also extends to surveillance and disruption. Drones can approach sensitive sites, monitor activity, interfere with operations or exploit vulnerabilities in physical security.
This creates a particularly difficult challenge for defence organisations: the same technology that makes UxS inexpensive, agile and readily deployable also makes the threat difficult to predict.
And the problem does not stop in the air.
Counter-UxS must address threats across air, sea and subsurface domains
Unmanned underwater vehicles (UUVs), autonomous underwater systems and other maritime platforms are creating a new dimension to the security challenge.
Undersea pipelines and communications cables are critical to national security and global connectivity. Their location and vulnerability make them attractive targets for hostile surveillance, mapping or potential sabotage.
Recent activity involving vessels suspected of surveying undersea infrastructure has highlighted the growing importance of protecting assets beneath the surface. At the same time, Ukraine’s use of unmanned surface vessels against naval assets has demonstrated the operational impact that maritime UxS can have.
The result is a rapidly expanding multi-domain threat environment.
For defence planners, this means Counter-UxS cannot be treated as a standalone “anti-drone” requirement. A modern approach needs to consider the full spectrum of unmanned threats – from airborne drones and loitering munitions to autonomous maritime and underwater systems.
High-profile events and critical sites face the same challenge
Military facilities are not the only locations at risk.
Major sporting events, airports, government facilities, nuclear sites and other high-value locations can all be exposed to UxS incursions. Even relatively small drones can cause significant disruption when deployed in crowded or sensitive environments.
A drone flying over a packed stadium, for example, can create a security incident, interrupt operations and potentially expose weaknesses in existing protection measures.
Nuclear facilities present an even greater concern. Reports of increased drone activity around Ukrainian nuclear sites illustrate how unmanned systems can create additional security and safety challenges around highly sensitive infrastructure.
Whether the objective is surveillance, disruption, coercion or physical attack, the fundamental challenge remains the same: how do you detect and respond to a threat quickly enough to protect the asset?
Passive observation is not an option
As UxS become faster, more affordable, more autonomous and capable of operating over greater distances, relying solely on passive observation is becoming increasingly difficult.
This is particularly important around high-value military assets where even a small window of vulnerability can have significant consequences.
Detection must therefore be paired with an appropriate mitigation capability.
That is where Counter-UxS technology becomes critical.
A modern Counter-UxS architecture should provide defence teams with the ability to:
- Detect and identify potential UxS threats
- Understand the operating environment
- Assess whether a signal or system represents a genuine threat
- Select an appropriate response
- Mitigate the threat with precision
- Minimise disruption to friendly and civilian systems
- Adapt as threat technologies and protocols evolve
The objective is not simply to “stop drones”. It is to give operators the information and tools required to make faster, more confident decisions.
Why RF intelligence matters in Counter-UxS
Radio frequency (RF) intelligence remains a fundamental component of modern Counter-UxS operations. Many unmanned systems rely on RF communications for command, control, telemetry and data transmission. Understanding activity across the RF spectrum can therefore provide valuable insight into the presence and behaviour of potential threats.
But the RF environment is becoming increasingly complex. UxS can use diverse frequency bands, changing protocols and increasingly autonomous operating modes. At the same time, defence teams must distinguish between hostile signals and legitimate civilian, military or friendly communications.
Without sufficient visibility of the RF environment, operators risk missing covert activity, generating false alarms or disrupting legitimate communications.
A sophisticated RF Counter-UxS solution can help operators build a clearer picture of the threat environment while enabling more targeted mitigation.
This is the problem BlackTalon’s passive and active RF detection was built to solve.
Precision matters as much as range
Counter-UxS effectiveness cannot be measured by range alone. Longer-range systems can provide greater protection around critical sites, but they also need to deliver the precision required to avoid unnecessary interference with friendly systems. This is where technologies such as directional jamming, high spectral purity and agile signal response become increasingly important.
Modern systems may need to address combinations of:
- GNSS signals
- Command-and-control links
- Telemetry
- Data links
- Multiple frequency bands
- Changing communication protocols
The ability to apply focused mitigation against a specific threat, rather than indiscriminately affecting the wider RF environment, can provide a significant operational advantage.
Directional capabilities have also expanded considerably, with effective ranges increasing from hundreds of meters to several kilometers in some applications. For military users, that means Counter-UxS systems can potentially be deployed further from the asset they are protecting, creating greater stand-off and allowing operators to respond earlier.
Counter-UxS needs to be mobile, scalable and adaptable
There is no single deployment model for protecting military and critical infrastructure.
A Counter-UxS system may need to operate from a fixed installation, a vehicle, a temporary operational site or the perimeter of a high-value facility. Mounting options and system mobility therefore matter.
Positioning sensors and mitigation systems at elevation can improve line of sight, while perimeter deployments can provide rapid response against approaching threats. In other situations, mobile systems may be required to support deployed forces or protect temporary assets.
With potentially hundreds of sites requiring protection, decentralised and scalable capabilities are increasingly important.
Defence organisations need solutions that can be deployed where they are required, integrated with existing systems and adapted as the threat changes.
Why an open Counter-UxS ecosystem matters
The Counter-UxS market is becoming increasingly crowded, and for defence organisations, this creates a difficult procurement challenge. Technology is developing rapidly, but no single vendor is necessarily able to provide every sensor, effect and capability required to address the complete threat landscape.
An open architecture can provide a different approach.
Rather than locking an organisation into one technology stack, an open Counter-UxS ecosystem can allow different capabilities to work together, combining specialist technologies from multiple vendors and enabling systems to evolve over time.
This approach can provide several advantages:
- Interoperability: Existing and future systems can be integrated rather than replaced.
- Adaptability: New sensors and mitigation technologies can be introduced as threats evolve.
- Scalability: Capabilities can be expanded across additional sites or operational environments.
- Resilience: Defence organisations are less dependent on a single technology or supplier.
- Investment protection: Systems can evolve without requiring wholesale replacement.
For military decision-makers operating in a rapidly changing threat environment, that flexibility can be just as important as the performance of an individual countermeasure.
From technology demonstrations to operational capability
The growing Counter-UxS market has produced no shortage of demonstrations, studies and technical claims.
But effective defence capability is ultimately proven in the field.
The most effective way to understand whether a system will work in a particular environment is through practical testing, realistic scenarios and continuous learning.
Threats vary between locations. RF environments differ. Terrain affects detection. Rules of engagement and legal frameworks vary. Operational concepts also differ between military organisations.
That makes a one-size-fits-all approach unrealistic.
Building the next generation of Counter-UxS capability
The UxS threat is developing too quickly for defence organisations to stand still.
All drones are becoming more capable. Autonomous systems are expanding into maritime and subsurface environments. Communication technologies are evolving. Threats can be deployed cheaply and at scale, while increasingly sophisticated systems can operate with greater autonomy and over longer distances.
The answer is not simply more equipment.
Defence and military organisations need integrated, adaptable and open Counter-UxS architectures that combine accurate detection, RF intelligence and precision mitigation with the flexibility to incorporate new technologies as the threat evolves.
Continuous testing, operational learning, interoperability and collaboration will be essential to maintaining an advantage as UxS technology advances.
The organisations best positioned to meet the next generation of uncrewed threats will be those that act now – sourcing a practical, scalable and future-ready Counter-UxS capability that can protect critical assets across every domain.
This approach is already being demonstrated through the continued development of the BlackTalon Ecosystem, which in 2026 alone has been enhanced to incorporate sonar sensing, cyber takeover capabilities and interceptor drone integration.
