Title 46 › Subtitle Subtitle V— - Merchant Marine › Part Part C— - Financial Assistance Programs › Chapter CHAPTER 531— - MARITIME SECURITY FLEET › § 53102
The Secretary of Transportation must set up and run a Maritime Security Fleet made of privately owned, U.S.-documented ships that have operating agreements with the government. The fleet is meant to help national defense and keep a U.S. presence in world shipping. To join the fleet, a ship must carry cargo in foreign trade, be self-propelled, meet the age limits (tank ships 10 years old or less; other ships 15 years old or less), be useful for defense as judged by the Secretary of Defense, be commercially viable as judged by the Secretary of Transportation, and be U.S.-documented or the owner must intend and be eligible to get U.S. documentation under chapter 121. The law allows several ownership and management setups so long as the owner or operator is a U.S. citizen or otherwise meets special security and approval conditions, and relevant officials notify Congress they agree. The Secretary of Defense can ask the Secretary of Homeland Security for any needed waivers under section 501. The Coast Guard may allow inspection certificates for some ships that were not U.S.-documented on the date of the Maritime Security Act of 2003 if they meet class, international rules, and flag-state enforcement standards. The Secretaries of Defense and Transportation can jointly waive or extend the age limits when it is in the national interest, to protect the ship’s business, or because no other compliant ships are available; they may increase the allowed ages by up to 5 years for a particular fleet vessel.
