Naval Vessel Register

From Wikipedia, the free encyclopedia

The Naval Vessel Register (NVR) is the official inventory of ships and service craft in custody of or titled by the United States Navy. It contains information on ships and service craft that make up the official inventory of the Navy from the time a vessel is authorized through its life cycle and disposal. It also includes ships that have been removed from the register, (often termed struck or stricken), but not disposed of by sale, transfer to another government, or other means. Ships and service craft disposed of prior to 1987 are currently not included, but these data are gradually being added along with other updates.

The NVR traces its origin back to the 1880s, having evolved from several previous publications. In 1911, the Bureau of Construction and Repair published the "Ships Data US Naval Vessels" that subsequently became the "Ships Data Book" in 1952 under the Bureau of Ships. The Bureau of Ordnance's "Vessel Register", first published in 1942 and retitled "Naval Vessel Register", was combined with the "Ships Data Book" under the Bureau of Ships in 1959. The NVR has been maintained and published by NAVSHIPSO since 1962. Referred to by Congress in the statutes of 10 U.S.C. § 7304–7308, the NVR is maintained as directed by U.S. Navy Regulations, Article 0406, of September 14, 1990.

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 is now available only in electronic form. It is available on the web (link) and is 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.
