EXPERTISE.
INDEPENDENCE.
PURPOSE.
Two decades of investment. A foundation for next-generation underwater capability.
For more than twenty years, Ocean Submarine has invested time, engineering expertise and financial resources in technologies for defence and offshore industries. Sustained research, product development and advanced manufacturing have created a technological foundation for international commercial programmes.
Independently owned and operating without bank financing or subsidies, we maintain direct control of our development priorities and commercial decisions. Discretion, reliability and long-term technical capability guide our approach.

NEYK N3 COMBAT SUBMARINE
DEVELOP THE TECHNOLOGY.
RETHINK THE PLATFORM.
A compact platform. A different approach to undersea defence.
The Neyk N3 brings together a distinctive hull form, modular systems and advanced propulsion development. Its mission-configurable architecture combines optical awareness, independent control systems and customer-selected sensors and payloads.
Ocean Submarine’s proposed energy concept aims to harness natural ocean-pressure differentials during underwater navigation. The objectives are reduced reliance on large battery banks, conventional fuel and stored oxygen, greater submerged endurance, and low noise and vibration. Energy balance, usable power, endurance and acoustic performance remain subject to independent validation and trials.
Customer-defined weapon and defensive-system options are intended to support maritime security, special operations and naval combat roles. Final capability and integration are established for each programme.
High-performance computing, hydrodynamic analysis and model testing underpin development. Ocean Submarine describes a multi-year programme involving manoeuvring simulators, towing tanks and deep-water facilities to refine propulsion, diving control and underwater handling.

BUILD CAPABILITY.
DEVELOP PEOPLE.
Sovereign production begins with industrial depth.
Ocean Submarine reports US$100 million invested in its Australian factory and production capability. The production model combines advanced forming equipment, robotic welding and modular assembly for submarine hull sections and critical steel structures. The focus is precision, repeatability and quality assurance against programme-specific requirements.
Participation in the Neyk Combat Submarine programme is intended to create practical training pathways in fabrication, assembly, inspection and systems integration. Our ambition is to develop a workforce at scale, with skills relevant to future naval construction and the wider submarine industrial base.
