Comparator
Conventional campaign
Vehicle, crew and support vessel move as one package.

Primary dependency
Support vessel
The support vessel carries the operating team and remains central to launch, recovery, charging and intervention.
Autonomous subsea systems
Persistent subsea autonomy, built around the mission.
Hydrogen-electric autonomous systems designed to remain useful across real decision windows, with vehicle, payload, replenishment and logistics developed as one architecture.
Civil + dual-useHydrogen-electricModular payloadsMission-system integration
Mission operating model
Endurance becomes persistence when the logistics change with it.
A vehicle must remain taskable, fuelled and serviceable for the full decision window. Andrasta designs the vehicle and its support model as one system.
Why compare the operating model?
Conventional campaigns repeatedly reunite the vehicle and its support chain. Andrasta separates those dependencies so vehicles can follow waypoints, remain on task and use distributed sustainment until the information is actionable or the mission and service state calls for recovery.
Interactive mission comparator
Offshore infrastructure + environmental assurance
Compare a periodic vessel-led campaign with waypoint-led systems designed to remain useful across real operational decision windows.
Replenishable model
Andrasta operating system
Waypoint tasking, long service intervals and portable fuelling are designed as one repeatable loop.

Actionable continuity
Decision window
Designed to stay on task across real multi-day and multi-week decision windows - long enough to turn observation into actionable information.

Mission 2028 · High Arctic
A planned Arctic under-ice transit before 2029.
A clear public objective for Andrasta's cold-water endurance thesis, and a defining proof point for a system designed around persistence from the outset.

Dual-use by design
One core architecture, configured for civil and dual-use missions.
The vehicle and energy architecture remain common. Payloads, operating boundaries, evidence and procurement routes change with the mission.
Civil
Offshore energy + infrastructure
Persistent environmental survey, subsea asset observation, inspection support, cable and pipeline monitoring, and decommissioning assurance.
Dual-use
Maritime awareness + seabed security
Long-duration sensing, infrastructure awareness, controlled trials, and integration pathways for operators and prime contractors.
Near-term development
Prototype quickly. Carry the learning into mission-scale systems.
Manta closes physical and integration risk quickly. AndraSound carries the lead persistent architecture into an operationally useful platform.

Persistent survey + maritime awareness
The lead persistent mission platform, with platform architecture and pre-integration design defined while research, design, and development continue.
Supplier readiness
Built for customer qualification as well as technical performance.
Quality, cyber, governance and supplier controls are developing alongside the vehicles, so procurement evidence does not become a late programme constraint.
