For the next two years, except for a brief October 1970 deployment to Greece in response to the Jordanian-PLO conflict, the destroyer operated on a routine schedule of type training, operational exercises, port visits and annual midshipmen cruises. After a three-month regular yard period in early 1972, "Barry" conducted refresher training, gunfire support qualifications and ASROC antisubmarine rocket firing tests in the Caribbean. Then, as part of a new forward deployment program, "Barry" began preparations to change her home port to Athens, Greece.
