All surface maritime vessels, military or not, need to advertise their location to anyone who can listen for the purpose of collision avoidance. If they didn't that would probably violate a treaty.
- WJW 4y agoMilitary vessels are exempt from that particular treaty. That would not be a significant worry. But yes, when you go into serious operations, the ship typically enters "black hole" operations where all non-essential communications are blocked. In the ships we were at they just pulled the network cable for the non-operational comms, very effective at preventing anyone from emailing back home.
