S12 Class

Medium-class autonomous underwater platform.

GPS-denied navigation.
Swarm-capable.
Modular effector-ready.
Production-scale.

Built for the Gap

Most underwater systems force a compromise. Speed or range. Autonomy or control. Capability or cost.

The S12 Class closes the gaps. It operates as a persistent AUV, a modular payload platform, or something in between. Field it for ISR, survey, mapping, inspection, or payload delivery. Configure it for sensing, signals, or intervention. Deploy it where endurance, autonomy, and scale matter. Capable enough for the hardest missions. Affordable enough to field in numbers.

One Architecture. Multiple Outcomes.

INStinct Navigation

Vatn’s Inertial Navigation System maintains accuracy in GPS-denied environments. Jamming. Spoofing. Total signal loss. It knows where it is when nothing else does.

Swarm-Native Autonomy

Vehicles share data, distribute sensing, and synchronize movement automatically. One operator can plan and monitor hundreds of units.

Modular Payload

Framework Sensor. Electromagnetic. Cyber. Decoy. Kinetic. Reconfigure without redesigning the platform. Adapt at the speed of need.

Volume Manufacturing

Designed for scalable production. Attritable. Replaceable. Fielded at quantity, not in theory.

CivTAK

VATN's CivTAK plugin enables multi-vehicle mission planning with pre-built behaviors, environmental auto-pathing, and near real-time tracking of hundreds of vehicles from a single interface.

ATAK

VATN's Android Tactical Assault Kit (ATAK) plugin gives operators real-time control of hundreds of vehicles via tablet or phone, with pre-built mission behaviors and direct integration into existing command and control (C2) systems.

Where It Works

ISR

Persistent sensing in contested waters without risking personnel.

Electronic Warfare

Distributed, attritable disruption assets deployed at scale.

A2AD Penetration

Infiltrate defended zones undetected. Deliver kinetic or non-kinetic payloads without vessel integration.

SOF Operations

Launch from small craft or air assets. Minimal signature. Rapid deployment.

Search & Recovery

Swarm-based grid division with automatic target identification.
