Seavex: Long-Endurance ISR USV
Seavex is Quantum Systems’ autonomous maritime missions hub. Designed as the central operational centre for maritime operations, this solution promises long-term performance excellence, convenience, and traceability.
Part of Quantum Systems Maritime Solution, Seavex is more than an autonomous surface vehicle (USV) with advanced core capabilities. It combines sensing, communications, and operational execution within a single autonomous hub that is also integrated with MOSAIC UXS. Serving as a reference point for all data touchpoints, Seavex turns information into actionable intelligence while enhancing situational awareness and efficiency.
Communication hub for maritime missions
As a mission, data, and management centre, Seavex works best through distributed and cross-team collaboration. One of its assets is its ability to coordinate multiple ISR drones, other Seavex mission hubs, as well as Subvex underwater systems as part of an autonomous maritime network.
The technology also facilitates Subvex docking, battery recharging, and secure data transfer, all from a single operational point. This allows missions to last longer and extend awareness across large maritime environments. Through a shared operational framework, Seavex can ensure mission execution by utilising its modular architecture and ability to handle multiple mission profiles, which are all managed through a shared medium.
Seavex: Maritime surveillance and extended air defence
Seavex comes in two mission configurations: maritime surveillance and active air protection, both managed through one platform.
The first configuration enables persistent ISR missions by bringing together durable technology and autonomous UAV deployment for continuous intelligence collection across air, sea and subsea environments. Designed for multi-asset and swarm-enabled missions, Seaver exhibits advanced counter-UAV technology that is part of a layered sensing, detection, and protection offering. Its MOSAIC UXS mission software unifies seavex hubs and other assets like Subvex underwater systems into a single collective eco-system that for better surveillance capabilities, interoperability, and ultimately successful technology deployment.
Active air protection is provided by the counter-UAS variant that expands the Seavex mission. The product is perfect for counter-UAV missions; Seavex offers active protection through integrated radar systems and drone interceptor capabilities, targeting aerial threats and enhancing air defence. Defence and protection include patrolling coastal areas, harbours, critical maritime infrastructure, and more. Working as part of an entire autonomous ecosystem, the solution ensures faster threat assessment, coordinated defence, and prompt mitigation.
