Field notes
The page describes target-motion analysis as a way to estimate a contact’s range, course, and speed from a passive sonar bearing. Its patrol list ranges from shadowing a ballistic-missile submarine to guarding a lost underwater drone until a salvage ship arrives. The site says the scenarios will include hidden variants, and some may end with a report that there was nothing to find.
