Class Notes:
On 20 August 1956 CNO, noting that the Fiscal Year 1958 Shipbuilding and Conversion Program as approved by himself on 3 July 1956 provided for the conversion of a World War II LST to an Advanced Aviation Base Ship, approved the Missions and Tasks for that type of ship. The mission was to provide mobile base facilities and logistic support for advanced base aircraft operations and the tasks included providing local control and support necessary to operate aircraft from an advanced base, to provide limited aircraft repair facilities to supported aircraft, and to provide limited command facilities and accommodations for a Fleet Air Wing Staff. Approved characteristics for an Advanced Aviation Base Ship (AVB) (LST conversion), SCB Project No. 177, were promulgated on 22 May 1958 and updated on 24 June 1959 and 26 April 1961. The ship selected for conversion was one of two experimental steam-propelled LSTs laid down at the very end of the war. By 1958 the conversion had been slipped to FY 1960 and was intended as a replacement for ALAMEDA COUNTY (AVB 1), which had been found useful by the aviation community. The ship was converted at NSY Charleston. Her after superstructure was extended forward, her forecastle was built up, and electronic antennas and a heavy kingpost were added amidships. As an AVB she was designed to provide command and logistic facilities to a squadron of anti-submarine patrol planes operating from an improvised land base. Squadron equipment was carried in mobile vans, transported in the ship's tank deck, and landed over her bow ramp. The classification of TALLAHATCHIE COUNTY was changed from LST 1154 to AVB 2 effective 15 September 1961.
