This is the ship my Dad served on. "The first half of 1957 was spent in readiness exercises off San Diego. John W. Thomason then sailed 29 July for a cruise which took her to Pago Pago, Aukland, and Manus. Upon arrival Yokosuka 7 September 1957 she resumed operations in the Formosa Straits and antisubmarine exercises with 7th Fleet ships. The ship returned to San Diego 8 January 1958, and conducted maneuvers off California and Hawaii." I have his certificate for crossing the Equator hanging in my room. I've had it since I was a child.
