CAPABILITY.
RECONSIDERED.
The operating environment is complex.
The platform should be adaptable.
Ocean Submarine develops compact crewed and uncrewed submarines for coastal defence, intelligence, surveillance and special operations support. The Neyk N3 brings a modular platform architecture together with customer-defined sensors, combat systems and mission equipment.
Designed to complement a wider naval force, the N3 focuses on littoral operations, distributed deployment and accessible maintenance.

REPEATABILITY.
INDUSTRIAL PURPOSE.
A coordinated approach from fabrication to fleet support.
Ocean Submarine’s production model brings advanced fabrication, robotic welding and modular assembly together with a selected network of specialist suppliers. Common components and accessible installations are intended to support fleet maintenance as customer programmes develop.
DEPLOYMENT FLEXIBILITY
THINK BEYOND
THE HOME PORT.
The N3 transport concept includes C-5 Galaxy airlift, subject to loading and operational approval. Compact dimensions and a modular approach provide a basis for discussing transport, support infrastructure and distributed deployment with the customer.

THROUGH-LIFE SUPPORT
ACCESS IS
A DESIGN DECISION.
Accessible forward hull +
A bolted connection with double O-ring seals is designed to provide access for major maintenance and equipment changes.
Common components +
Interchangeable dive planes, motor gondolas and selected components are targeted across the fleet to support repair and replacement planning.
Adaptable installations +
An internal frame is designed to simplify electrical, hydraulic and cabling changes. Accessible equipment arrangements are intended to support upgrades without cutting open the pressure hull.
