Integrated Navigation & Tactical Systems – Retrofits and New Builds

For over three decades, OSI Maritime Systems has worked with leading shipyards and primes to provide advanced integrated navigation and tactical solutions to military customers. Our teams travel the world, working directly with shipyards and delivering OSI systems onboard platforms, be it new builds or retro-fits.

Delivering Bridge Systems to Time, Cost, & Budget

We understand the importance of time, cost, and budget and have the experience to zero in on mission-critical activities and get the job done. Each and everyday somewhere in the world an OSI navigation system is being installed. We have proven leadership, and 25 Naval Customers worldwide with more than 700 warships and submarines operate with OSI systems.


We’re more than uniquely surface operators, OSI’s experience extends to Submarines. Our systems are operational on 18 classes of submarines, and our Tactical Dived Navigation System is recognized as the leading navigation system for subsurface warfare. That means that when an OSI system is integrated into a submarine, the shipyard will be getting a system that has a track record for installation ease, and the customer will be getting leading-edge nav capabilities.

Offering 24/7 support tailored to the Customer’s needs, provides the peace of mind that there is a certified technician standing ready to support their queries in their local shipyard.

Systems for Submarines

In a submarine, space economics is defined by weight and confinement. Confined space requirements start with building systems that will fit in the submarine and are deisgned with modulaty so that the system can be moved and fitted in the desired operating location. Highly experienced in submarine system ergonomics, our systems leverage technical know-how second to none and exploit space efficiencies to ensure that the submarine crew gets the most from their navigation system.
