Why anti-submarine forces still mistake whales for targets

How can navies prevent whales from being attacked during anti-submarine operations?

Better sensors reduce mistakes, but submarines and whales both blend into ocean noise, and long-range positive identification remains difficult.

Modern submarines are designed to disappear into the acoustic background of the sea. Whales use related concealment in hunting, which creates overlapping signatures under uncertain combat conditions. Sensors can improve classification, but a guaranteed long-range identification method does not exist. Uncrewed underwater vehicles already perform extensive mine-countermeasure work. Extending their role to anti-submarine identification would mean approaching a contact and relaying imagery or other data. Underwater bandwidth and range limits make that confirmation difficult to obtain before a weapon decision. Some risk of misidentification therefore remains inherent in anti-submarine warfare.
