Defence Plasticity® is a unique design philosophy, inspired by neurophysiology, that seeks to build a new generation of defence and security products capable of learning in response to emerging threats, changing both form and function while still deployed. This design philosophy informs Quell’s AI platform Deep Truth®, and our range of standalone software and hardware additive manufactured products.
Our technology is “plastic” in the biological sense: our physical products can adapt to meet novel threats without requiring a return to a factory, base or dockyard for refitting or reprogramming.
The Deep Truth® software can also be used to enhance the capabilities of existing legacy equipment that has outlived its manufacturers’ upgrade options.
Quell’s range of solutions includes anti-air, ground, and maritime threat detection, as well as counter-surveillance and concealment technologies that protect military assets, civilian infrastructure, and critical national infrastructure.
Quell has created new defence and sentry technology to counter drone, vehicle and human threats. Quell’s systems can be used for civilian, critical national infrastructure and military applications. They can protect personnel, vehicles, vessels, stadiums, airports, energy plants and maritime facilities just as effectively as they support front-line defence operations. Whether safeguarding critical infrastructure or securing contested environments, the purpose is the same: to provide real time threat intelligence and proportionate response.
Our Deep Truth® AI platform powers all our products. Deep Truth® is our proprietary AI framework, comprising a suite of server-side and client-side software. It includes a continuously expanding set of primary analytical functions, application logic and operator workflows.
Deep Truth® does not rely on any single algorithmic approach. Instead, it is designed to scale and learn, enabling multiple machine learning methods to operate in concert.
Deep Truth® features unique, proven real-time decision-making capabilities across exceptionally diverse data types. For example, it can visually classify entomological species, detect subtle material defects, distinguish between various types of drones, and differentiate between biological and man-made flying objects. It can also recognise patterns of behaviour and analyse transmission signatures across packet data, audio and radio signals.
Deep Truth® can be purchased as a standalone software option or integrated into our hardware solutions. It is designed to address a wide range of complex, known problems while also learning new solutions to tackle previously unknown challenges.
The threat posed today by unmanned aerial and maritime systems is unprecedented, both in military and civilian contexts. Inherently inexpensive compared to conventional military equipment, drones possess a disturbing and versatile range of capabilities.
On land, at sea, or in the air, and with or without a controlling pilot, drones can remotely target and eliminate individuals and machines. Capable of operating in swarms with heavy payloads, they can launch relentless attacks, causing mass casualties or destroying critical infrastructure from great distances. What was once easily concealed on a battlefield is now easily detectable. Moreover, this new class of weapon systems can rapidly evolve — often within days — rendering countermeasures ineffective.

SkySpyke® is Quell’s counter-unmanned aerial and surface close-in threat detection and neutralisation system. Built from first principles and informed by our Defence Plasticity® design philosophy, SkySpyke® is powered by Deep Truth® software. This gives it the unique ability to track, identify and neutralise evolving unmanned threats as they develop.
Operating in real time and all weather conditions, SkySpyke® provides a passive, 360-degree optical view of its environment. It can function as a standalone unit or as part of a distributed network of cooperating units. SkySpyke® is mountable on vehicles, aircraft and maritime vessels. Uniquely, it can operate both statically and while in motion, requiring minimal operator training and offering flexible levels of human input.

Spyke®
Spyke® testing in the field
Spyke® is a hand-carry unit designed to provide aerial coverage for a defined portion of the sky – ideal for small vehicles and mobile units for approach-corridor and perimeter monitoring. Spyke® offers portable, high resolution directional surveillance with an extended battery life, supporting long-duration dismounted operations.
Individual Spyke® units can operate alone or in data-sharing groups to protect almost any arbitrarily defined defence line or positional topology. Spyke® units are independent building blocks that can be clipped together to form SkySpyke®s. It takes six Spyke® units and an optional top unit to form a SkySpyke®.
Protection of Critical National Infrastructure
Since 2018 – with the closure of Gatwick Airport due to drone incursions – there have been at least 28 reported full or partial closures of international airports due to drones.
Quell’s range of products pair Deep Truth® machine learning with modular hardware to serve both civilian protection and tactical defence.
For example, SkySpyke® and Spyke® form large-scale sentry and warning systems that detect, classify, and track all types of aerial and ground threats, providing operators with a real-time picture and visual identification of human, vehicle, or airborne threats to support rapid decision-making. From nuclear facilities to stadiums, airports, ports, and offshore platforms, SkySpyke® and Spyke® units can be vehicle-mounted, statically deployed, and daisy-chained to provide continuous coverage of critical infrastructure, regardless of size.

MASC
MASC (Modern Automated Specialist Camouflage) is an Al-generated, organomorpic camouflage pattern generation and object detection software, powered by Deep Truth®.
Today, even the most advanced camouflage patterns still rely on a developer’s subjective selection of salient visual features, hues and colours from the landscape they aim to mimic. Their effectiveness therefore remains fundamentally dependent on human skills and choices. MASC, in contrast, provides an empirically measurable extraction and generalisation of the most relevant visual features in any given setting.
A MASC user can select any terrain or urban scene and train the system to produce a wearable pattern using a single image or a collection of photographs.
Patterns can be created for any scale of object requiring protection, from personnel to vehicles. MASC’s patterns can be generated instantly, in real time, to match anything from highly localised positions to large-scale environmental vistas, with options for user-selected seasons or daylight conditions.
Conversely, MASC is also learning to detect man-made camouflage patterns. It ingests live video and/or digital images to automatically identify manufactured camouflage.
When placed on vehicle-mounted displays, MASC camouflage can automatically change surface camouflage patterns to match contrasting environments. For illustrative purposes, a British Ajax Armoured Fighting Vehicle is shown moving through urban, woodland, and cornfield settings. As it progresses, its surface camouflage changes to match each background at the exact moment it is encountered.
WiSAD
Passive Counter-Surveillance – a silent, portable, undetectable electronic warfare system
In combat, WiSAD alerts users to unseen incoming hostile forces and tracks their movements, allowing the user to evade, move or persist in theatre undetected. In an urban setting, WiSAD detects and tracks those who are attempting to watch, listen or follow you.
WiSAD interprets the complex signalscape surrounding the user, notifying them of the presence of devices within the surrounding area, making it possible to locate, track and identify individuals, units and equipment on a battlefield or in the urban environment.
WiSAD uses Deep Truth®’s probabilistic framework to passively listen to wireless signals within a kilometre range to determine which devices are present and potentially hostile.
WiSAD does not transmit any signal. Instead, it listens ‘passively’ to surrounding broadcasts, using its proprietary antenna assembly. As a passive device, WiSAD remains undetectable and effectively silent, gathering surrounding signal intelligence without the use of the discoverable transactional processes inherent in most spyware and cyber hacking techniques.
