Naval agreements are international treaties or contracts between two or more countries that regulate the use of naval forces. These agreements can cover a wide range of topics, such as the size and composition of naval forces, the rules of engagement, and the rights and responsibilities of each party. The term 'AYES' is an acronym for 'Agreement for the Yielding of Equipment and Services, ' which is a type of naval agreement that allows one country to provide military equipment and services to another.
