“Isn’t the officer in charge of a ship ALWAYS called the Captain, regardless of his rank?”..
Ding, Ding, Ding!!!!! We have a winner. Indeed a “Captain” of a U.S. Navel vessel can be any rank of commissioned officer such as Ensign, LTJG, Lt., LT. Commander, etc..
And in case this comes up, a Lt. Commander or Lt. Colonel are always referred to as Commander or Colonel.
All ranks of Admiral are referred to as Admiral
Chief’s of all ranks called Chief except for the Master Chief. He is referred to as Master Chief.
