Olongapo is the city outside the former US Naval Base and now outside of the Subic Bay Freeport Zone.
Zc856. The Navy Mothball Fleet in the 1960s or before at San Diego. When I went to my basic training in San Diego, 1960, I remember that I bought a postcard like this. Those many ships, that was impressive. This image came from this webpage: https://www.reddit.com/r/HistoryPorn/comments/2g952r/the_san_diego_mothball_fleet_in_1946_this_was/
I’m sure; the mothball Fleet at Subic Bay was not that big, ha, ha! I remember going to the Palau Island in the 1970s and inspect ships, mothballed there.
