S6 Class

Compact modular underwater effector.

Man-portable.

Swarm-capable.

Attritable at scale.

Small Enough to Carry. Effective Enough to Matter.

The S6 is a portable unmanned underwater vehicle (UUV) built for distributed operations. Launch by hand, from a USV, small craft, workboat, UAV, or aircraft. One operator plans and monitors hundreds of units. Efficient by design. Effective at scale.

Common Core. Configurable Edge.

INStinct Navigation

VATN's inertial navigation system keeps the S6 on course in GPS-denied conditions, whether jammed, spoofed, or fully denied.

Swarm-Native Autonomy

S6 units coordinate automatically using swarm tech. Shared data, synchronized movement, distributed sensing. A single operator manages the fleet.

Modular Payload Framework

Swap between sensor, electromagnetic, cyber, decoy, and kinetic payloads without redesigning the vehicle.

Man-Portable Form Factor

One person can carry and deploy the S6, within minutes. No handling infrastructure. No specialized launch equipment. Marine robotics made fieldable.

Built for Scale

Designed from day one for high-volume manufacturing. Attritable. Replaceable. Produced at quantity, not in theory.

Plan once.
Deploy at scale.

Mission planning is unified across the S-Class. Plan, simulate, deploy, and monitor fleets through Vatn’s mission planning tools. TAK-compatible where required.

Port & Infrastructure Security

Continuous autonomous patrols of hulls, piers, pipelines, cables, and offshore assets.

ISR

Persistent sensing in contested waters without risking personnel.

Electronic Warfare

Distributed, attritable disruption assets deployed at scale.

A2AD Environments

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.

Ready When It Matters.
