Dark Skies: The Role of Multilayered Air Defence at the Frontline
Ivor Humphrey, Directed Energy and Maritime Missile Sales Manager
With traditional air defences struggling to keep up, and nations looking to adapt, it’s clear that what worked previously won’t work when facing an increasingly complex and inherently unpredictable aerial landscape.
The aptly named ‘dark drone’ flies fast and undetected, bypassing sensors to arrive with deadly intent, all without raising any alarms.
“We’re not ready for what is coming our way in four or five years,” Mark Rutte said recently. Scenarios, such as the above, embody the NATO Secretary General’s stark warning.
No doubt, in part, he had in mind advanced ballistic missiles, capable of traveling thousands of miles, and hastening urgent calls for the UK to increase spending on air and missile defence. But while ICBMs present a substantial challenge, transformation on the battlefield comes from threats that are smaller, readily available and potentially vast in number. Drones – proliferating and exploiting rapidly advancing technology to hide from view – are reshaping how we think about frontline protection.
The need for an Integrated Airspace-protection Systems (IAS) approach – blending human-machine-teaming, rapid-response systems and layered defence networks – has never been more urgent. Fulfilling this need requires a fundamental shift in how armies are defended, structured and resourced, both in strategy and mindset.
The Tactical Challenge: Survivability
Whether from a foxhole or a battle tank, a soldier under-fire likely has one thought permeating their headspace: “See first, shoot first, survive another day.” But the asymmetric threats posed by one-way, dark, and swarm drones are turning situational awareness into a relentless challenge more akin to “see more, shoot more, survive another hour”. As they spread, proliferate and open up new lines of attack, it’s not without some irony that FPV drones both amplify this challenge and offer an advantage, making survival a race to outsee and outgun the enemy in real time.
Such threats need layered, integrated, defensive systems if they’re to be countered effectively. Identifying dark drones, for instance, requires layering multiple sensors into a detection and monitoring package – a system designed with RF detect, radar and optical sensors that can not only identify the presence and location of the drone but also that of the operator. Armed with the ability to disable the arrows as well as the archer, soldiers can claw back the time to reset, recalibrate and respond in kind.
This layered approach is part of a larger, integrated IAS strategy that blends advanced algorithms, AI, sensor integration, kinetic weapons and EW to detect, engage and neutralise masses of UAS’ that threaten to converge and swarm all at once. In such situations – where every second counts and the sheer volume of noise, danger and data can overwhelm human judgement – advanced algorithms and AI can help reduce the cognitive burden of operators, enabling them to do what they do best - make fast and evidenced decisions.
Combined with the effect of Radio Frequency Direction Energy Weapons (RFDEW), these technologies are capable of defeating close-in mass swarm attacks that would overwhelm traditional air defence measures – protecting soldiers, safeguarding systems, and enabling mission success.

In a mass swarm scenario, technologies like Radio Frequency Directed Energy Weapons (RFDEW) are particularly well-suited for countering small, fast-moving drones within tight timeframes.
’ RapidDestroyer can neutralise swarms of drones for just pennies per shot, making it an ideal companion to conventional short-range air defence systems like the Lightweight Multi-role Missile (LMM).
The Operational Challenge: Interoperability
NATO Steadfast Defender 24, the Alliance’s largest exercise in decades, comprised 90,000 troops across 32 allies. The clarity of the exercise’s aim – to be a “clear demonstration of our unity, strength and determination to protect each other, our values and the rules-based international order” – belies the technical complexity behind it.
Integrating different defence systems, both within national forces and across allied coalitions, is as much an astonishing feat as it is an imperative task. The British Army – and forward-deployed nations more widely – are recognising more and more that they can’t operate in isolation. Countering the aerial threats of peer and near-peer adversaries not only requires layered systems, sensors and effectors but also layered nations.
Different member states, branches of service or even deployed contractors will bring something different to the battlefield, creating a patchwork of technologies and operational procedures. As modern systems integrate into traditional air defences, this patchwork only becomes bigger, messier, harder to manage and increasingly fragile. Even one wrong stitch can lead to vulnerabilities in joint operations.
The success of deployments and exercises like Steadfast Defender is, of course, determined by their people – but the technical prowess is defined in terms of open architectures and interoperability standards that allow for more flexible integration across diverse technologies.
The Strategic Challenge: Procurement
The value of these integrated technologies isn’t some intrinsic, immutable quality – rather, it lies in what they empower personnel to do. It’s a value that can’t be realised if they’re not reaching the front line in time.
Technology cycles are accelerating. In Eastern Europe, quick and dirty innovation is flourishing on the battlefield as both sides study, test, replicate and improve on each other’s threats and defences. Yesterday’s dark drone might be tomorrow’s drone-hunting-drone, for instance, often rendering hard-won advantages obsolete in a matter of months. To keep up, defence must shift from gold-plated procurement to spiral capability development: a constantly-on and rapidly evolving process of development, design acceptance and delivery, at a higher TRL than before.
The ends may be clear, but the ways and means are complex and multifaceted. Armed forces, industry and researchers all have a part to play in agreeing and accelerating adaptive, agile procurement models that support ongoing R&D and iterative integration. When it comes to fostering innovation, reward must be balanced with risk; careful consideration and strategic testing will be needed to prevent missteps and safeguard against the pitfalls of premature adoption. Early-stage prototyping, field testing and continuous feedback loops can help here, allowing for real-time adjustments that refine technologies through practical use.

Given the intent from the MOD, the skill from industry and the will from both, there’s no reason to think procurement can’t be transformed from a transactional process into a tactical asset – a dynamic, agile ally that moves as fast as the battlefield.
Layering the solution, limiting the threat
Calls for 'MOD-led, industry-enabled innovation' provide a blueprint for how defence companies and the end customer must collaborate, with agility, to accelerate bringing the latest technologies into service. When the MOD requested that accelerate its RF Directed Energy Weapons into service, for instance, we rallied the partners and, together, we’re working on getting RapidDestroyer off the production line and onto the front line as early as later this year.
More widely, NATO’s ability to preserve peace hinges on rapid adaptation, integration and innovation among and between its allies. A multilayered defence strategy demands a similarly dynamic approach to technology design, development and procurement, driven by cross-domain expertise, nimble procurement and heavy investment in R&D.
Mark Rutte’s warning is an unignorable reminder: as the battlefield promises nothing apart from rapid, inevitable change, the only constant will be the need for bold, collaborative and agile defence innovation. The point isn’t whether we can adapt; it’s that we must adapt fast enough.
