Naval Vessel Register 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 "Ships Data US Naval Vessels", which 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. Since 1962, the NVR has been maintained and published by the NAVSEA Shipbuilding Support Office (NAVSHIPSO) of the Naval Sea
