Which of the following systems is primarily used by the U.S. Navy for electronic navigation?

The Electronic Charting Display Information System - Naval (ECDIS-N) is specifically designed for the U.S. Navy to enhance electronic navigation capabilities. This system integrates various navigation data with layered electronic charts to provide comprehensive situational awareness at a high level of precision, which is essential in military operations. ECDIS-N is tailored to meet the specific needs of naval operations, including features that support tactical decision-making and mission planning.

The use of ECDIS-N allows for increased efficiency and safety in navigation, especially in complex maritime environments. It provides real-time data, which is crucial for making informed navigational decisions during various operational scenarios. The system supports interoperability with other naval systems and is compliant with military standards, further solidifying its role as the primary navigation tool for the U.S. Navy.

While the other systems mentioned in the choices do serve important functions in navigation and charting, they do not cater specifically to the needs of the Navy in the same way that ECDIS-N does. For instance, the Civilian Electronic Charting System (ECS) is more commonly used in commercial maritime operations and does not provide the military-specific functionalities that ECDIS-N offers. The Vector Mapping System (VMS) and the Global Positioning System
