Summary

The United States must have a merchant marine with five goals. It must carry the country’s waterborne domestic trade and a substantial part of its waterborne exports and imports and keep shipping moving; be able to serve as a naval and military helper in war or national emergency; be owned and run as U.S. vessels by U.S. citizens; use well-equipped, safe ships built in the United States and crewed by trained U.S. personnel; and be backed by good shipbuilding and repair facilities. The U.S. will encourage and help build and maintain a merchant marine that meets these goals.
