Quantum Systems

Quantum Systems develops autonomous maritime systems for naval surveillance, infrastructure protection and counter-UAS missions. Its Seavex unmanned surface vessel and Subvex underwater vehicle bring complementary sensing and mission capabilities to maritime forces. Connected through MOSAIC UXS, the company’s AI-enabled mission combat system, these platforms form part of a wider defence portfolio spanning air, land and sea.

Maritime surveillance and critical infrastructure protection

Naval forces need to understand activity around ports, offshore installations and subsea infrastructure while maintaining awareness farther out at sea. Quantum Systems meets these requirements with a maritime architecture that combines aerial observation, surface surveillance, and underwater sensing. The focus is sustained coverage and information that operators can use to assess changes in their area of responsibility.

Applications include monitoring maritime approaches, protecting offshore energy assets and observing activity near communication cables and pipelines. Distributed sensing also supports maritime border security and monitoring underwater contacts. Combining observations from different positions helps operators interpret activity in its wider maritime context.

Unmanned ground vehicle (UGV) engineered for high-speed, heavy-duty missions in defense and disaster response environments. Designed around a modular architecture, it adapts to a wide range of operational roles.

Fully integrated mission software built for existing and future battlefield management, ground combat, and aerial systems. It delivers seamlessly integrated command and control of unmanned systems in the air, on land, and at sea.

Reliant is a Group 3 vertical take-off and landing (VTOL) fixed-wing unmanned aerial system (UAS) that combines long-range endurance with rapid, infrastructure-free deployment.

High-speed, cost-efficient interceptor UAV purpose-built to counter long-range loitering munitions and ISR drones. Designed to close the capability gap between legacy air-defence systems such as Patriot and counter-drone solutions.

Twister is a compact eVTOL sUAS that delivers visual and acoustic aerial intelligence for critical short-range ISR missions in military, defence, and public safety sectors.

Vector AI, the new iteration of combat-proven Vector eVTOL sUAS, builds on years of operational experience, with thousands of mission hours across global military operations, including its proven effectiveness in Ukraine.

Converting heavy-duty tactical & military logistics vehicles into unmanned, autonomous assets. Advanced from Europe’s first TÜV-certified autonomous trucking solution in civil logistics, it enables automated & teleoperated driving functions for defence platforms.

First German multi-role aircraft with optional piloting capability - The aircraft can support crewed, remotely controlled, or uncrewed operations, enabling forces to adapt the same platform to changing mission requirements.

Seavex unmanned surface vessel and maritime mission hub

Seavex provides a surface base for autonomous maritime operations. It combines surveillance sensors, communications and support for other unmanned assets, allowing naval users to extend their presence across an operating area. The platform is designed for endurance of up to two months and payloads of up to 400kg, with mission configuration and operating conditions determining achievable performance.

Its role extends to sustaining assets deployed above and below the surface. Seavex supports autonomous UAV launch and recovery, alongside Subvex docking, recharging and data transfer. This gives operators a way to combine aerial reconnaissance with underwater collection around a shared maritime hub. Additional Seavex and Subvex platforms can expand the network as coverage requirements increase.

Subvex underwater sensing and subsea surveillance

Subvex adds an underwater perspective to maritime intelligence gathering. The unmanned underwater vehicle combines sonar and hydroacoustic sensors with onboard AI processing to support the detection, classification and monitoring of subsea activity. Its published operating depth is up to 6,000m, opening a broad range of underwater observation roles.

For naval and infrastructure security users, potential missions include monitoring sensitive seabed areas and gathering information around underwater assets. Subvex can operate independently or within a distributed network, with Seavex providing docking, energy and data services. Connecting underwater observations with surface and air information helps operators assess contacts in the context of the wider mission.

Maritime counter UAS for ports and offshore assets

Counter-unmanned aircraft systems, or cUAS, add an air protection role to the maritime portfolio. In its interceptor configuration, Seavex combines radar-based monitoring with interceptor deployment to support protection of ports, offshore infrastructure and naval operating areas. MOSAIC UXS connects the associated sensor information and mission coordination.

This configuration places aerial threat monitoring within a distributed maritime network. It provides a complementary layer of protection that can be planned alongside surface and underwater surveillance, with the selected sensors, interceptors and operating concept matched to the customer’s requirements.

MOSAIC UXS connects maritime air and ground operations

MOSAIC UXS provides the software backbone across Quantum Systems’ domains. It brings sensor information, mission planning and unmanned asset coordination into a common operational framework. For maritime users, this supports a shared view of activity observed by aerial, surface and underwater systems, while keeping operators in command.

The same architecture connects air and ground capabilities and supports integration with third-party platforms and command environments. Open interfaces allow customers to build around their operational requirements and existing investments. MOSAIC UXS coordinates the network; cUAS contributes the dedicated detection, tracking and interception capabilities used to address aerial threats within it.

Air and ground systems extend the connected portfolio

Beyond maritime platforms, Quantum Systems supplies aerial reconnaissance systems, including Reliant and Twister, and the Mandrill unmanned ground vehicle. Mandrill’s MOSAIC UXS integration supports shared awareness and coordinated air and ground missions, with roles including reconnaissance, logistics and force protection.

Across these domains, cUAS is a separate protective capability within the wider portfolio. Skyron 400 illustrates this connection: its MOSAIC UXS integration brings radar information and interceptor control into the software environment. Maritime and ground deployments can therefore be considered within a broader approach to protecting forces and infrastructure against airborne threats, with integration defined for each application.
