My dad served on the USS Essex CV-9 "The Oldest and the Boldest" in the early 1960s and participated in the Cuban blockade.
My dad was a Boilerman on it in the 60's.
As http://www.essex.navy.mil/history/history.htm states: "USS Essex (LHD 2) is the fifth ship to proudly carry the name Essex. It would not take much research to find each of the four former ships with their name etched in history."
