Vessels are listed in the NVR when the classification and hull number(s) are assigned to ships and service craft authorized to be built by the President of the United States, or when Chief of Naval Operations requests instatement or reinstatement of vessels as approved by the Secretary of the Navy. Once listed, the ship or service craft remains in the NVR throughout its life as a Navy asset. Afterwards, its final disposition is recorded.
The NVR now exists as an electronic document only, found at http://www.nvr.navy.mil/. It is maintained and updated weekly. Over 6,500 separate record transactions are processed annually with each being supported by official documentation. The NVR includes a current list of ships and service craft on hand, under construction, converted, loaned/leased, or to be loaned, and those assigned to the Military Sealift Command. Ship class, fleet assignment, name, age, homeport, planning yard, custodian, hull and machinery characteristics, builder, key construction dates, battle forces, local defense and miscellaneous support forces, and status conditions are some of the data elements provided.
