Purpose and Scope

To provide information to Ship Owners, Operators, Masters and Officers regarding the interaction between Naval forces and commercial shipping. In particular, this publication serves as a handbook for the world-wide application of NCAGS principles and procedures that exist to enhance the safety of shipping in times of tension, crisis, or conflict.

Where necessary, the lead responsibility for the implementation of NCAGS will be as follows:

In the Area of Operations (AOO): The Military Commander (MC).

In NATO countries and their overseas territories: The nation concerned.

In all other areas: One NATO nation is to assume responsibility on behalf of NATO, as agreed among members.

A lower level of NCAGS procedures (eg picture compilation) may be activated before the implementation of an NCAGS operation, either by NATO or nations involved.
