USS Chikaskia (AO-54)
Underway, probably circa 1953-55, with all four 3"/50 single mounts removed. She had them in images dated 4 November 1952. The forward 40mm quad mount was also removed, leaving the forecastle unarmed. Later views show her armament further reduced to 2-3"/50 singles aft. Sister Chipola lost her four 3" guns in 1952, recovered them by 1954, and lost the forward pair again by 1962 (below). Tolovana lost her four in 1951 but recovered them all for good by 1957. Photographed by Allied Photographers, San Francisco.
