USS R-12 (SS-89) was found in 600 feet of water off Key West, Florida, in October of 2010 by an exploration team led by Tim Taylor aboard the expedition vessel "RV Tiburon."  According to their website, "In making the discovery, the team deployed a state of the art autonomous underwater robot which collected first ever imagery of the remains of R-12. They are collaborating and sharing their findings with the US Navy." RV Tiburon is planning additional expeditions to further investigate the possible causes of the sinking, and collect detailed archeological baseline data.

A small get-together was held in Key West in June of 2013 to commemorate the loss of the vessel.
