Thanks, mine was Benjamin Franklin (SSBN 640). 1973 to 1976. MM1SS.
I was aboard USS Bonhomme Richard, CVA-31, for a short period in 1969 as part of a Marine Amphibious Unit (MAU) afloat off of the coast of I Corps/II Corps South Vietnam. It was a memorable experience.
Earlier during that time afloat, I had been aboard the USS Guadalcanal, one of the first generation of purpose built helicopter carriers (LPH - no well deck). So I had something to compare to the Bonhomme Richard.
There was no comparison. Bonhomme Richard was a full sized WWII fleet aircraft carrier repurposed for service as a helicopter carrier. Needless to say, it had a lot of unused capacity. Still, during my short time aboard - it was just a couple of days going between the shore and the other ship in the ARG my unit was assigned to - I got a chance to walk around the ship. My mind kept recalling all the carrier operations scenes from the Victory at Sea television series. Here I was actually walking the decks of one of those ships still in active service after all those years.
