RRF meaning in Governmental ?

The National Defense Reserve Fleet (NDRF) consists of "mothballed" ships, mostly merchant vessels, that can be activated within 20 to 120 days to provide shipping for the United States of America during national emergencies, either military or non-military, such as commercial shipping crises.

The NDRF is managed by the U.S. Department of Transportation's Maritime Administration (MARAD). It is a different entity from the United States Navy reserve fleets, which consist largely of warships.

NDRF vessels are at the fleet sites at James River, Virginia (James River Reserve Fleet); Beaumont, Texas (Beaumont Reserve Fleet); and Suisun Bay, California (Suisun Bay Reserve Fleet); and at designated outported berths. Former anchorage sites included Stony Point, New York (Hudson River Reserve Fleet); Wilmington, North Carolina; Mobile, Alabama; Astoria, Oregon; and Olympia, Washington.

Through the 2010s, the oldest, most decrepit hulls at Suisun Bay were stripped of toxic materials, then broken up in Texas, California, or Asia. Twenty of the most polluting mothball ships were slated for recycling by 2012, and another 32 by 2017.

At its peak in 1950, the NDRF had 2,277 ships in lay-up. In 2003, it had 274. In July 2007, it held 230 ships, primarily dry cargo ships with some tankers, military auxiliaries, and other types. As of July 2021, the number of ships was down to 86.
