Hi Chuckleface. Navy ER nurse here. I did ROTC, not NCP, but I would love to answer other Navy nursing questions. In regards to your original post, Navy nurses go out on the USNS Comfort and Mercy. There also is a small opportunity for nurses to go on fleet surgical team ships (OR/ICU nurses mostly) The Comfort and Mercy go out typically once every two years. The Mercy is on the west coast and Comfort is on the East coast. Currently the Comfort is out providing medical relief for Puerto Rico. As the Navy provides medical care for the Marine Corps, Navy nurses do deploy with Marine units in field type medical units. The types of nurses that typically deploy with these units are ER/ICU nurses. Most Navy nurses begin as medsurg nurses and later decide what specialty they want to do. (ER/ICU/OR/etc). I would say Navy nurses don't deploy very often like most members of the military, but you would still have the opportunity especially if you specialize in ER/ICU. Feel free to message for other questions. Cheers!
