 operations. Its stated mission is "to use the naval force of the federation for the exterior defense, and to help with internal order". The Navy consists of about 56,000 men and women plus reserves, over 189 ships, and about 130 aircraft. The Navy maintains a constant modernization program in order to upgrade its response capability, although its programs are hindered by a lack of funding due to variable budgets and lack of continuity.
