Solving counter-drone vehicle integration challenges

Military drones have transformed modern warfare, offering advanced surveillance, precision strike capability, and rapid battlefield awareness at a fraction of the cost and risk of manned aircraft. Nowhere is this more evident than in Ukraine, where both sides rely heavily on unmanned systems ranging from small quadcopters to long-range strike drones. Since 2022, the Ukraine invasion has been a brutal and telling example of modern battlefield tactics, most notably drones formed a key part of offensives and defensive action, albeit in smaller numbers than today. As the war has progressed both Ukraine and Russia have received a huge expansion in their drone arsenal from a combination of foreign governments, private companies and domestic industry.
As drone capability continues to expand, so too does the need for effective counter-drone (C-UAS) technology. However, integrating these systems into already space-constrained military vehicles presents a significant challenge. One promising solution lies in adopting common digital architectures, such as the Generic Vehicle Architecture (GVA), which enables standardised integration across platforms.
The Rise of Military Drones
Unmanned aerial systems (UAS) have evolved from niche reconnaissance tools into indispensable battlefield assets. Modern drones provide excellent intelligence, surveillance and reconnaissance (ISR) without risking human pilots, while also enabling precision strikes with guided munitions. Their relatively low cost and rapid deployability make them accessible at scale, and their versatility allows them to range from palm-sized quadcopters to large, long-range strike platforms.

Ukraine: The Modern Drone Battlefield
The war in Ukraine has become the most drone-intensive conflict in history, demonstrating both the effectiveness and accessibility of unmanned systems. Forces on both sides employ a wide range of drones, including small commercial quadcopters for trench reconnaissance, FPV (First Person View) drones for direct attacks on armoured vehicles, soldiers, and longer-range systems targeting logistics and infrastructure. In earlier stages of the invasion, low-tech DIY counter drone defences included nets (often fishing nets or mesh) over vehicles and trenches with limited success. Electronic warfare, despite its significantly higher associated costs, is often much more effective and plays a major role, with both sides attempting to jam or spoof opposing drones.
Ukraine's use of platforms such as the Bayraktar TB2, alongside thousands of improvised FPV drones, highlights how rapidly drone warfare has evolved. At the same time, the conflict underscores the urgent requirement for robust and scalable counter-drone solutions.
Counter-Drone (C-UAS) Technology
As drones become more capable and widespread, counter-drone technologies must advance in parallel. Modern C-UAS systems typically rely on a layered approach that combines detection, identification, and mitigation capabilities.
Detection and tracking are achieved using radar, RF sensing, acoustic sensors and electro-optical/infrared (EO/IR) systems. Identification increasingly relies on AI-assisted classification and signal analysis. Counter drone measures range from electronic attack (jamming and spoofing) to kinetic or directed-energy solutions. Despite these advances, several challenges remain. Small drones are difficult to detect due to their low radar signature, and urban environments create significant sensor clutter. Electronic warfare is highly contested, with both sides actively disrupting each other's systems and critically, many C-UAS solutions are still too bulky and complex for easy integration into existing vehicle platforms.

Space Limitations in Military Vehicles
Military vehicles are already densely packed with mission-critical systems such as communications equipment, battle management computers, sensors, weapon control interfaces, and power distribution units. Adding a complete C-UAS suite—including radar, antennas, processors and effectors—places additional strain on space, power and data bandwidth. Traditional “bolt-on” integration methods exacerbate these issues by introducing redundant hardware, excessive cabling, increased weight and more complex maintenance requirements.
As a result, space and integration constraints have become a major barrier to the widespread deployment of counter-drone capabilities across ground forces.
GVA: A Common Architecture for Integration
The Generic Vehicle Architecture (GVA), developed in the UK and mandated by MOD for future platforms, provides a standardised framework for integrating electronic systems within military vehicles. Rather than treating each system as a standalone installation, GVA defines a shared digital backbone through which systems can communicate and operate.
This approach reduces duplication by enabling shared processing, displays, and interfaces, while also minimising cabling and simplifying system integration. Importantly, it allows new capabilities to be added without requiring a complete vehicle redesign, making it particularly well suited for rapidly evolving technologies like C-UAS.
What is UltraEAK®?

Ultra PCS, part of Eaton, has developed a truly open, modular and scalable GVA solution called UltraEAK®. The Electronic Architecture Kit provides seamless integration of the data and power needs for military vehicle systems. It comprises of the processing, networking and power distribution hardware, along with mission system software.
The mission system software is delivered through the Platform Gateway Interface (UltraPGI). At its core is the means of describing the data exchange mechanism, the “middleware” that glues all the mission system components together. On top of this is the User Interface (UI) that provides an intuitive means of interacting with the platform systems, whether simple lighting commands or complex mission planning and routing. The middleware (using the Land Data Model) and UI are fully compliant with the GVA standard.
Sub-systems interface with the core by creating plug-ins - a software module that adapts the sub-system interface into the common GVA language. UltraPGI can not only interface the mission system components, but also gateway to an existing platform databus, whether that's a simple CANbus or something more complex such as Victory.
By reusing modules/plug-ins developed from previous projects/vehicles and only developing new modules where a new feature/vehicle is encountered, UltraPGI is technically and commercially open as the system includes an API allowing vehicle integrators and third-party manufacturers to develop their own mission system interface into GVA.
Creating an eco-system of platform manufacturers and mission sub-system partners, Ultra PCS is leading the way in deploying a truly open electronic architecture that meets the needs of platform integration today and into the future.
Integrating Counter-Drone Technology with UltraEAK®
Integrating C-UAS systems using UltraEAK® aligns closely with modern operational requirements. Rather than introducing standalone hardware packages, counter-drone capabilities can be embedded directly into the vehicle's existing digital architecture.
This approach enables more efficient use of space and resources, as sensors and effectors connect to a shared infrastructure. Processing can be centralised, removing the need for dedicated C-UAS computers, while operators can use existing displays and controls. The result is a more streamlined, maintainable system that can be deployed rapidly across multiple military vehicle types.
A Future Proof Solution, with UltraEAK® at its core
Military drones are reshaping the battlefield, with the conflict in Ukraine clearly demonstrating both their effectiveness and their vulnerabilities. While counter-drone systems are essential, their integration into space-constrained military vehicles remains a significant challenge.
Common digital architectures such as GVA, combined with platforms like UltraEAK®, offer a practical and future-proof solution. By embedding counter-drone capabilities into a shared digital backbone, militaries can deploy advanced defensive systems without compromising space, weight, or usability.
