In September 2026, Quantum Systems launched the Seavex unmanned surface vessel, a 4,500kg platform designed for extended maritime intelligence, surveillance, and reconnaissance operations. The vessel, which debuted alongside the Subvex underwater vehicle, is currently a fully realized platform capable of operating in sea states up to level 6.
Why it matters
Seavex provides persistent maritime awareness and supports distributed operations by leveraging onboard edge computing to process complex environmental data. This capability enables autonomous target detection and mission planning over deployment durations of up to two months.
The Seavex vessel features two Nvidia Jetson Orin AGX modules to process data from a 4D anti-drone radar with a 15nm range and a 2D surveillance radar with a 48nm range. It maintains 3D mission situational awareness using MOSAIC UXS software to translate high-level objectives into actionable surface instructions.
The players
Quantum Systems
An aerospace and defense company specializing in unmanned aerial and surface systems utilizing edge AI and advanced sensor integration.
The details
The platform functions by integrating machine learning frameworks with computer vision algorithms to autonomously scan and identify targets. MOSAIC UXS, a proprietary software interface, generates 3D representations of the surrounding maritime environment to execute mission parameters without constant manual oversight. A multi-modal communications suite, incorporating 5G, satellite, Wi-Fi, and Silvus tactical data links, ensures data integrity across diverse operating conditions.
Timeline
The Seavex surface vessel and Subvex underwater vehicle launched in Portugal in September 2026.
The Tech Race
The deployment of Seavex represents a strategic move toward highly persistent, autonomous maritime monitoring within the competitive market for unmanned surface vessels. This platform marks a step toward greater integration between surface and subsurface autonomous systems, expanding the industry focus beyond aerial drones.
This technology is designed for maritime surveillance and security, primarily impacting defense and environmental monitoring workflows rather than consumer use. Future iterations will likely influence how distributed maritime grids are managed by allowing users to maintain persistent awareness across 6,000m depths via the paired Subvex UUV.
The takeaway
The arrival of the Seavex vessel highlights the industry's shift toward high-endurance, AI-integrated maritime platforms capable of handling harsh sea states. Interested observers should monitor the announced deployment of the Subvex underwater vehicle, which supports deep-sea operations down to 6,000 meters.
