Developed and designed specifically for military and border forces, Defendec is an autonomous intrusion detection system for remote areas. Our system combines rugged, easily camouflaged devices, ultra-low power design, and state-of-the-art artificial intelligence for reliable intrusion detection with minimal human intervention.
Defendec devices have been deployed in the field since 2009 and are used to protect over 35 country borders.

We are developing and manufacturing mobile autonomous surveillance systems, USV’s, C-UAS and multi-layer with AI-powered C2. Our turn-key solutions are for border security, coastal surveillance, defence and critical infrastructure protection and are built for diverse mission profiles, including specialized adaptations for challenging environments such as deserts. Our systems are combat-proven.

Our main products are:
– Mobile autonomous situational awareness system SurveilSPIRE
– Vehicle-based rapid intelligence and targeting system with sensors CAIMAN
– Mobile all-terrain C-UAS EIRSHIELD with various effectors
– Cutting-edge AI-powered C2 software
– An Unmanned Surface Vehicle for various naval missions EUROMITE

Frankenburg missile is a next-generation interceptor missile built to defeat today’s most urgent aerial threats – drones and loitering munitions – with unmatched efficiency. Solid rocket-fuelled, fast, and lightweight, it’s the smallest and most agile missile in its class. Designed from the ground up for rapid deployment and ease of use.

Frankenburg missiles will be ten times more affordable than traditional air defence missile systems and available at scale, produced locally to strengthen national defence industries and directly support local armed forces. In Ukraine, Shahed drones are taken down by missiles which cost tens of times more than the drones themselves—an unsustainable approach. We are determined to solve this cost-per-kill ratio in favour of our customers. Fully designed and developed in Europe, ensuring secure supply, operational control, and export flexibility. Missiles are a 100% ITAR-free solution, aligned with European defence standards and compatible with allied systems.

Hevi Optronics is designing and developing precision-engineered electro-optical sensor systems for commercial and defence applications. We are integrating the latest sensor technologies and video enhancement algorithms into a modular system architecture. We provide stand-alone and turn-key solutions for Air, Land, Sea and Surveillance markets and offer relevant support and system integration services.

KrattWorks offers a jamming resilient short range multirotor reconnaissance drone with multi-band radio and GNSS-free capabilities. The ISR Ghost Dragon drone is developed based on the lessons learned from Ukraine.

KrattWorks also offers aerial target drones, which include fast-flying fixed-wing DART platform for air-defence missile and cannons shooting practice. Additionally, KrattWorks provides small PARM multirotor targets for small arms counter drone drills.

Our loitering munition drone Dart-X delivers 10 kg payload to 100 or 200km distance. The decoy version Dart-R is equipped with radar reflectors to match the desired radar footprint.

High-mobile defence systems – what is it? 

It is a custom designed, manufactured and equipped deployable shelter system.

The goal is to facilitate faster responsiveness, better cost efficiency and lower environmental impact compared to the traditional ”bricks and mortar” infrastructure.

The system allows to transport defence services close to the defence action operatively – in minutes – and gather all the defence tactical needs where they were not feasible before, creating possibilities for new defence strategies and innovation to be implemented.

Our systems support the defence capacity by increasing the sense of security of the defence forces, with providing back security with first aid and recovery facilities, food and ammunition supplies.

MARU Defence design 

Our high-mobile systems are a constantly evolving toolbox, with which we can test and develop an infrastructure and service solution for goals, no matter how complex or unusual.

Therefore we offer not only ready-made systems, but design system solutions for any need or vision that the client needs to cover.

We believe in co-creation, inventing together with the defence forces, their direct experience and vision, shaping the most suitable and innovative solution.

With the help of partners, we equip and furnish the system exactly as designed.

Skeleton Technologies builds the power infrastructure layer for mission-critical systems, with three main business areas: AI data centres, grid solutions, and defence. As modern defence platforms become increasingly electrified and software-defined, they face a growing constraint: managing extreme, instantaneous power and energy demands. This is rapidly becoming a strategic bottleneck. Skeleton addresses this challenge with advanced supercapacitor-based solutions delivering instant power, pulse power, and ultra-fast response capabilities, already integrated across missiles, counter-UAV systems, land vehicles, and naval platforms.

Founded in 2012, Threod Systems is one of the most experienced Estonian defence technology companies specializing in the development and manufacture of advanced unmanned aerial systems. Our mission is to enhance battlefield situational awareness and operational effectiveness through reliable, combat-proven solutions. Threod develops and produces three core product groups: VTOL UAS; multifunctional electro-optical payloads for aircrafts; and probably the best pneumatic launcher systems for one-way effectors in the world.

The 5.0 Robotics Executive Series aids military logistics by providing frontline CNC solutions for on-demand production of digitized parts, ensuring immediate readiness and adaptability even in the most challenging environments.
