Which model of SINS is installed or being installed on surface combatants?

The AN/WSN-5 is a noteworthy model of the Ship's Inertial Navigation System (SINS) that is specifically used in surface combatants. This system plays a critical role in providing accurate navigation data by utilizing inertial measurement technology, enabling precise positioning and course data essential for the operational effectiveness of naval vessels.

The AN/WSN-5 is designed to integrate well with other navigation systems and contribute to the combat readiness of surface combatants by ensuring reliable navigation even in challenging conditions where traditional navigational aids may not be available or are compromised. Its installation on surface combatants reflects the ongoing advancements in navigational technology critical for modern naval operations.

In terms of other models mentioned, they serve different functions and may not specifically cater to the surface combatant requirements as the AN/WSN-5 does. For example, some models are designed for different platforms or have different roles that are not centered on inertial navigation for surface combatants.
