Class Notes:
Approved characteristics for a new construction fleet oiler (AO), SCB Project No. 82, were promulgated on 20 May 1953 and updated on 18 April 1958. AO 145 and 147 were ordered from Ingalls on 28 Jan 1952 but that contract was cancelled on 28 Feb 1952 and they were reassigned on the same date to NYSB.

On 14 May 1959 a team from the Preliminary Design Branch of BUSHIPS (Code 421) visited AO 147 and AO 143 to get their crews' reactions to this relatively new AO type in connection with new design work in progress(notably the AOE type). They learned that the AO 143 type ships had experienced no difficulty in replenishing operations in up to force 4 winds due to poor seakeeping or lack of stability and that roll stabilization features were unnecessary. The ships had, however, experienced major trouble with green water inundating the main deck and even the forecastle, smashing up and completely disrupting the deck load cargo of AvGas drums and pressurized gas cylinders on the main deck and causing structural damage on the forecastle. The ships suggested that the main deck forward be enclosed. Visibility from the bridge was considered fine since the removal of the forward centerline mounted 5" gun. The most serious criticisms related to the machinery plant. Opinion was unanimous that the ships were underpowered in backing, that the two boilers were insufficient, and that the ship service generators were inadequate to the extent that starting up the fire room forced draft blowers created a serious power drop on the line followed by a power surge that burned out lights and electronic components. The Executive Officer of NEOSHO summarized the general feeling concenting the machinery plant by called it "archaic." When shown the AOE design the officers of the two ships endorsed most of its features except the 40-foot draft, which they pointed out was too much for nearly all harbors on the U.S. East Coast, including Norfolk, to handle.

As of late 1954 the draft FY 1956 shipbuilding program included one SCB Project 82 AO. Approved characteristics for a fleet oiler (AO), SCB Project No. 82A, were promulgated on 21 October 1957 with a single change on 12 November 1957. Approved characteristics for an oiler (AO), SCB Project No. 217, were promulgated on 20 September 1961 without later changes. Neither project resulted in new ships.
