Class Notes:
FY 1942 (AO 51-64), 1944 (others). In mid-December 1941 the Navy began developing a list of its total requirements in ships for a maximum war effort. On 12 Jan 42 the General Board submitted to SecNav a list of the additional ships of each type that would be required, including 12 high speed oilers (CIMARRONs). On 14 Mar 42 CNO promulgated to the Bureaus an updated "Maximum War Effort (Shipbuilding)" tabulation that included the 12 CIMARRONs plus two more for conversion to escort carriers, noting that it furnished a reasonably accurate list on which to base planning and material needs. The two tanker escort carrier conversions quickly disappeared but the oiler requirement soon increased to 3 CIMARRONs to be delivered in 1943, 8 in 1944, and 3 in 1945. Anticipating Navy requirements, the MC on 20 Mar 42 ordered under its Military Program 14 repeat CIMARRONs, a design it now designated T3-S2-A1, from the Bethlehem Steel Co. yard at Sparrows Point, Md. On 9 May 42 the Auxiliary Vessels Board recommended acquisition of these 14 oilers from the MC. At the same time the Board also approved the other auxiliaries listed in the Maximum War Effort program for delivery in 1943: nine tenders to be built on C3 hulls (AD 22-25, AV 14-17, and AS-23), two more C3-type tenders to be acquired (AR-12 and AS-22), and two ammunition ships to be built on C2 hulls (AE 8-9).

On 6 Jun 1944 the JCS asked the MC to modify its building program for the first half of 1945 to include the construction of 56 merchant type vessels as Naval auxiliaries including 12 oilers. On 14 Jun 44 the MC reassigned to the Navy six T2-SE-A2 tankers then under construction at Marinship for civilian use (AO 91-96), and on 15 Jun 44 it ordered under its Military Program four more fast oilers of the T3-S2-A1 type from Bethlehem Sparrows Point (AO 97-100). The MC informed the JCS on 22 Jun 44 that it was able to provide for all of the requested 56 ships except for two of the 12 oilers. On 3 Jul 44 the Auxiliary Vessels Board recommended acquiring the 54 ships including the 10 oilers.

AO-51, AO-98, and AO-99 were jumboized in 1964-65 and as such are listed separately in the "Auxiliary Ships Since 1945" section of this site as the ASHTABULA (AO 51 Jumbo) class. See that section for more details on their conversions including photographs.
