Background
The Ready Reserve Force (RRF) is the Maritime Administration (MARAD) program which provides sealift of supplies for the U.S. military throughout the world. The RRF supplements the Maritime Prepositioning Program which has strategically located ships pre-loaded with United States Army or United States Marine Corps equipment.
The former commercial vessels of RRF sit empty while they await call-up. Under the program, the ships must be ready for loading and sailing within 4, 5, 10, or 20 days. Those assigned 4 and 5 day readiness have a permanent skeleton crew of 9 or 10 mariners. Private shipping companies under contract to MARAD provide maintenance, activation, manning, and vessel operation.
The Department of Defense periodically tests readiness of the RRF by initiating no-notice activations, and by routine activations for military cargo operations and exercises. RRF ships are also used for cargo handling training by Navy Reserve and Army Reserve units. When activated, control of the RRF ships transfers from the Maritime Administration to the Military Sealift Command, part of the United States Navy.
The Offshore Petroleum Discharge System (OPDS) was designed by and for the Navy, for use with the Army and Marine Corps' Inland Petroleum Distribution System (IPDS). The OPDS is stored aboard a selected Ready Reserve Fleet tanker. It is transported to a theater of operations by the tanker. The OPDS provides 1.2 million US gallons (4,500 m3) per 20-hour day of refined petroleum to the beach, from a tanker moored four miles (6.4 km) from shore. The tanker is crewed by civilians.
Other OPDS tankers are the SS American Osprey, SS Petersburg, and the SS Chesapeake.
The United States Merchant Marine is an organization composed of United States civilian mariners and U.S. civilian and federally owned merchant vessels. Both the civilian mariners and the merchant vessels are managed by a combination of the government and private sectors, and engage in commerce or transportation of goods and services in and out of the navigable waters of the United States. The Merchant Marine primarily transports domestic and international cargo and passengers during peacetime, and operate and maintain deep-sea merchant ships, tugboats, towboats, ferries, dredges, excursion vessels, charter boats and other waterborne craft on the oceans, the Great Lakes, rivers, canals, harbors, and other waterways. In times of war, the Merchant Marine can be an auxiliary to the United States Navy, and can be called upon to deliver military personnel and materiel for the military.
The National Defense Reserve Fleet (NDRF) consists of ships of the United States, mostly merchant vessels, that have been mothballed but can be activated within 20 to 120 days to provide shipping during national military emergencies, or non-military emergencies such as commercial shipping crises.
