When the writing project was developed the parameters for this series were designed to cover only commissioned US Navy ships with assigned names. If the ship was not assigned a name it was not included in the histories written for the series.[1]In addition to the ship entries,DANFS and the online links have been expanded to include appendices on small craft, histories ofConfederate Navy ships, and various essays related to naval ships.
DANFS was published in print by theNaval Historical Center (NHC) as bound hardcover volumes, ordered by ship name, from Volume I (A–B) in 1959 to Volume VIII (W–Z) in 1981. Several volumes subsequently went out of print. In 1991 a revisedVolume I Part A, covering only ship names beginning with A, was released. Work continues on revisions of the remaining volumes.
Volunteers at the Hazegray website undertook to transcribe theDANFS and make it available on theWorld Wide Web. The project goal is a direct transcription of theDANFS, withchanges limited to correcting typographical errors and editorial notes for incorrect facts in the original.In 2008 the NHC was re-designated as the Naval History and Heritage Command (NHHC). It has developed an online version ofDANFS (seeExternal links section below) through a combination ofoptical character recognition (OCR) and hand transcription. The NHHC is slowly updating its onlineDANFS to correct errors and take into account the gap in time between the print publication and the present date. NHHC prioritizes updates as follows: ships currently commissioned, ships commissioned after the original volume publication, ships decommissioned after original volume publication, and finally updates to older ships.[11] The NHHC has begun a related project to place Ship History and Command Operations Reports online at their site.
As theDANFS is a work of the U.S. government, its content is in the public domain, and the text is often quoted verbatim in other works. Many websites organized by former and active crew members of U.S. Navy vessels include a copy of their ships'DANFS entries.
TheDictionary limits itself largely to basic descriptions and brief operational notes, and includes almost no analysis or historical context.
