No but I did serve as ship’s nurse on a carrier for 2 years and I assure you that being stationed on a warship is completely different than being TAD to a hospital ship. I had to go through every workup cycle prior to deployment (something hospital ship RNs don’t have a clue about). It is a complete nightmare. I was responsible for the medical department’s participation in about 8 inspections including CART I, II, and III, TSTA/FEP, COMPUTEX, CQ’s, etc. if any of these were failed then the ship couldn’t be certified to deploy (which is a huge stressful deal). So yes I consider the Comfort/Mercy luxury cruises. It was a tough job but I actually liked being in the fleet around real surface warfare officers and crew, instead of being stuck around mostly other doctors and nurses onboard.
