U. S. Navy Auxiliary Vessel Types and Classes, 1980-2021


With the exception of tankers the procurement of traditional auxiliary vessels came to a near halt in the years after 1980, although specialized types contiuned to be built or acquired. The following are the types and classes built or acquired between 1980 and 2021. Only five of the type designations in this list were in use in 1945 (AGS, AH, AK, AO, and ARS). Ships with four-digit accounting numbers instead of Navy hull numbers as designators (mostly prepositioning ships from the merchant marine) are excluded, as are AKR 112-113 which were also accounting numbers.
