|Submarine Hull Markings
When a submarine is commissioned It has the hull number painted on either side of the sail and the bow, The ship name is on either side of the stern. These look nice but are not practical. As soon as possible the bow and stern markings are painted out. If the sub is not going to be on operations for a while or for special occasions the hull numbers are painted on the sail. When on operations there are no hull markings. The old location on the sail were on the lower aft sides. The new location is the top center of each side.
The modern subs have magnetic hull numbers, that are removed after getting underway, and prior to submerging.
