with excellent military capabilities

The newest type NEYK submarine with a fully pressurized single hull has excellent military capabilities. With an overall length from 19m (63ft) to 22m (73 feet) and has excellent stealth features and a very low noise profile. It has the capability to bring a complete team of Navy Seals and all its equipment undetected to almost on shore of any place on earth. Its standard diving capability of 300m (1000 feet) can be upgraded. But the Marine version of our NEYK also can deploy a lot of other military tasks. From gathering intel to active warfare.

Either for gathering information or tactical purposes the NEYK submarines will be a weapon system of its own kind. It can deploy a rapid force on any coast for infiltration or retracting purposes. It can be fitted with an extra layer of stealthy provisions. It primary and secondary weapon system are very versatile. But most of all its compact size, very low noise profile and incredible agile manoeuvrability will help every submarine commander to get his task accomplished.

The NEYK can be equipped with various weapon systems. Most likely the Navy version of our NEYK will be fitted with two launching tubes for either all types of torpedo’s or mines and missiles. Besides that, it can also be rigged with various kind of defending weaponry.

The “NEYK” combat system provides the best platform for processing all gathered intel. The NEYK can function as an unseen sentinel collecting all kind of e-lint by any system you wish or eyeballed reconnaissance by its strong tactical periscope. And it can do that for a long time without surfacing.

The customer can have a choice of any combat system he likes with every type of sensor passive active ranging or intercept. This can go from a cylindrical array sonar, passive sonar, echo sounder, Intercept sonar, active sonar, self-noise indicators and all types of navigation and communication systems, standard underwater telephone, various radar systems and tactical night vision equipment for the periscope.

The NEYK by Ocean Submarine is modularly built and comes with a single pressure hull. The hull is reinforced with rafters spaced at 60 centimetres apart for maximum security. The overall design guarantees a very low hydrodynamic drag, a high shock resistance and a very low noise signature. The bow section varies to order. The submarine has spaciously dimensioned panoramic acrylate portholes for excellent sight from the cockpit. With its hydraulically driven retractable undercarriage The NEYK is the only submarine that can land by driving up a ramp by itself.

The new NEYK submarine is completely built modular. The private versions have a single pressure hull that is only slightly tapered in the rear for maximum inner space. That is where the oxygen bottles are stored. All parts as mid ship, conning tower, stern and bow sections are made of high-yield steel HY-100 (produced by Marel to meet RNIN specifications).

The bow section is not welded but bolted to the hull and can vary to order. For military use is it is likely fitted with a steel version that can contain weapons or electronics.

The NEYK can easily be airlifted to any place in the world. To transport the vessel, the vertical diving rudders and the complete tower can be removed within one hour only. The three retractable wheels with hydraulic propulsion gives the submarine the possibility to drive up any elevations up to 7 degrees such as ramp. The complete submarine can drive itself into a transport airplane like a C5-Galaxy or Antonov An-225.

THE luxury


Every submarine commander will love our Navy version of the NEYK series for its highest achievable comfort for his crew and its excellent handling. The revolutionary steering design makes the vessel the most agile submarine ever made. All integrated electronical control and monitoring systems makes the submarine completely operated by wire and easy to handle with only two joysticks. That makes manoeuvring very precise and predictable. The NEYK either can turn on its keel within seconds or hoover within centimetres at one spot.

The NEYK submarine can be rigged as a fast stealthy and deadly naval force to be reckoned with.

It really is the most agile underwater vessel ever build. Due to the two separately placed main engines that separately can be reversed, four vertical diving rudders and a main rudder, a bow and a stern thruster the whole submarine can turn on a dime in only seconds. And this without causing cavitation. Hoovering is also brought to the next level. The NEYK can stay actively in one place by the use of two extra vertical thruster placed in the dome on top of te tower that can give up and downforce. It can do this completely computerised at pre-set parameters.

For any Navy men on a high risk mission, the absolutely stealth concept will be a real reassurance. Also its very rugged design will be very comforting. The NEYK is a boat that can endure a beating. And think about installing provisions like high pressure chamber with inside an air lock and to the outside an extra hatch to let divers in and out under water. That hatch also can be of great value in rescuing other submarine crews if necessary.

Power and propulsion

The main propulsion of the NEYK is provided by two electrical nearly noiseless motors that are placed in two pods outside the pressure hull. The pods are specially designed to give the propellers more efficiency up to five percent and provide extra cooling at low speed. The revolutionary design also provides low drag and a very low underwater noise signature.

The electrical power is generated by a diesel engine. The engine provides the power for the electrical main propulsion and bow, stern and vertical thrusters when surfaced or at snorkelling depth and charges the batteries.


Ocean Submarine provides the diesel driven Rolls-Royce 4000 U83 generator as a standard. Other makes of engine can also be built in. For the electrical propulsion we use 100 kW motors as a standard. However, more powerful engines or more recreational types can be ordered.

Extra features

Standard the NEYK submarine comes fully navigable with all necessary navigation systems, a fully integrated periscope, systems for surface and under water communication and safety equipment. But our NEYK submarine is a very flexible diving platform. Every vessel is unique and can be rigged with almost every piece of equipment to meet even the most demanding customer requirements.

Ocean Submarine also provides the necessary training and certification of the crew.
