In March 2013, during a routine training exercise, dolphins in the U.S. Navy's Marine Mammal Program made a surprising discovery: a rare 19th-century torpedo. While working off the coast of San Diego, California, two dolphins indicated the presence of an unknown buried object. Subsequently investigated and recovered by Navy divers, the object turned out to be a 110-year-old Howell torpedo developed by the U.S. Navy. The Space and Naval Warfare Systems Center Pacific (SSC Pac) contacted the Naval History & Heritage Command's (NHHC) Underwater Archaeology Branch (UAB) about the discovery. Shortly thereafter, arrange- ments were made to transport the artifact to NHHC's Archaeology & Conservation Laboratory in Washington, D.C., for stabilization and conservation treatment.
