The navy is charged with several important (and some constitutionally mandated) missions: 1. Maintenance of free seaways, and security for the billions of tonnage of goods shipped on the seas. 2. Training, maintaining and equipping of combat-ready forces. 3. Deterring aggression and preventing hostilities against allies. 4. Defending the rights of the United States and its allies to move freely on the ocean. 5. Maintain a superior force capable of winning the wars of the nation. U.S. Navy training manuals state the mission of the U.S armed forces is "to prepare and conduct prompt and sustained combat operations in support of the national interest". As part of that establishment, the U.S. Navy's functions comprise sea control, power projection and nuclear deterrence, in addition to "sealift" duties. Which of these do you think is not worthy? And which, if not done effectively, would result in wars or conflict, piracy or humanitarian aid not rendered at time of need? We were the first on the scene after the tsunami in Indonesia as well as the earthquake in Haiti. Without naval forces, we are helpless to help. But having served in the Navy, I can speak to their professionalism and superiority compared to every navy in the world. I would not want to live in a world not patrolled by the Navy, a global force for good.
