The Gearing class destroyer, DD-805, did cruise the pacific during the 1950's and early 1960's; but there are no sources indicating that she "worked the gunline" during the Vietnam War. I served on the Chevalier from early 1969 through late 1970. We cruised twice to westpac and worked many missions including naval gunfire support, plane guard, piraz, sar, and shoreline interdiction. Each cruise was 6-8 months. I have a year book from the 1968 cruise which illustrates similar action.
USS Pueblo
The USS Oriskany was an aircraft carrier. It was in both the Korean and Vietnam War. It was designed to hold between 90 and 100 airplanes. It would hold up to 2,600 crew members.
There were no American naval ships lost during the Vietnam War.
US Airmen and Sailors conducted war against NORTH Vietnam with their airplanes and battleships (one battleship actually, the USS New Jersey), cruisers, and destroyers firing from the gunline. US Soldiers and Marines fought on the ground in SOUTH Vietnam.
It might be easier to state which USN aircraft carriers did not serve in Vietnam. In which case the answer would probably be none. Nearly all US carriers conducted a WESPAC cruise to either Yankee or Dixie Station (North or South Vietnamese Coastline). Three of those carriers suffered terrible fires/explosions during the course of the war: USS Enterprise, USS Oriskany, and the USS Forrestall. No carrier was directly attacked by the enemy; only the USN destroyers USS Maddox, USS Higbee, and cruisers USS Boston & USS Oklahoma City suffered direct attacks by the North Viet Air Force or North Vietnamese Navy. And the USS Boston's story would take a whole different chapter to tell.
In 1959.
USS Pueblo
yes 1969
NO
No
Yes. The USS Enterprise launched jet fighter bombers over Vietnam, becoming history's FIRST atomic powered warship to engage in combat.
It's tours in Vietnam were 1965 to 1968.
The USS Repose most likely has a website, go to them.
Yes
The USS Flasher (SSN-613) was deployed to the western Pacific at intervals during the Vietnam conflict, so, yes, it was operating in support of military activity there.
Nearly every vessel in the United States Navy participated in the war. USS Vancouver (LPD-2) was no exception. See website on: USS Vancouver (LPD-2).
