Still There in the Action.
The United States Navy has a rich history when it comes to submarines that were never heard from again after completing their missions. If it is believed that a submarine has submerged or been lost in some other way, the official status of the submarine will change to “still on patrol.”
It’s romantic to think that maybe one day it may come back to you, but we all know that this will never actually happen. However, this does not preclude the possibility that the military will make an effort in the future to discover further information regarding the whereabouts of the submarines that are currently thought to be lost.
