Notes for this website


This list does not include auxiliary types that consisted entirely of conversions from major combatants or of experimental combatants. These types include AB, ACV, APD/LPD, AVD, AVG, BACV, and BAVG. For these see Bauer and Roberts, Register of Ships of the U.S. Navy, 1775-1990, Major Combatants. It also does not include types or ships for which no hull numbers were assigned. It does include minelayers, which were sometimes classified as combatants but which otherwise resembled auxiliary types. It also includes LSV 1-6 because of their derivation from the large AN and CM designs. Finally, it also includes conversions from minor combatants (patrol, mine, and landing craft) to all auxiliary types except IX since no volume of the Register exists for minor combatants (a few are covered in the Major Combatants volume). APY and ATL were preliminary designations for LSTs and APM 1-8 were preliminary designations for LSD 1-8; these are not covered here.

In armament data, the "less-than" character (<) is used to indicate that the number of small guns of the type specified (almost always 20mm) varied within the range shown during a period in which the larger armament shown remained constant. For example, the entry 4-5"/38 4<9-20mm indicates that the number of 20mm guns varied between 4 and 9 during a period when the larger armament remained steady at 4-5" guns. The < character may thus be considered roughly equivalent to the words " up to." During World War II, the variation usually consisted of a steady increase. After the war some variations were increases, many were decreases, and some were more complex, consisting of both increases and decreases. A steady decrease is indicated by the "greater-than" character (>), which corresponds to the words "down to." All guns are in single mountings unless marked "T" (twin) or "Q" (quadruple), although a "S" (single) is sometimes optionally added for clarity. Note that for multiple mounts (T, Q) the quantity shown refers to mounts, not to guns (8-20mmT have 16 barrels on 8 mounts).The dates shown for the armaments are those between which the armaments were installed and their small guns modified, not the entire periods during which they were carried.

Abbreviations for fates include BU (broken up), Canc (cancelled), Dest (destroyed), FLC (Foreign Liquidation Commission), MA (To MA, purpose unspecified), MA/D (To MA for disposal, usually sale), MA/R (To MA for NDRF reserve), MA/S (To MA for sale, usually at or near time of sale), MA/T (Permanent title transfer to MA from custody status for reserve or sale), MC (To MC, purpose unspecified), MC/D (To MC for disposal, usually sale), MC/R (To MC for NDRF reserve), MC/S (To MC for sale, used for smaller vessels), RTO (returned to owner), Scrp (scrap), Susp (suspended), Tgt (target), Trf (transferred).
