On July 17th, the NHHC Underwater Archaeology Branch (UAB) along with partners from Ocean Technology Foundation, Naval Oceanographic Office, SUPSALV, Mobile Diving and Salvage Unit (MSDU) 2 and the US Naval Academy, set out to continue the search for one of the Navy’s first fighting vessels, Bonhomme Richard. Captained by the father of our Navy, John Paul Jones, the ship was lost in 1779 after engaging in combat with HMS Serapis off the Yorkshire coast of England. Although Jones emerged victorious, Bonhomme Richard was irreparably damaged. After transferring all men and supplies safely to the captured Serapis, Jones set the beleaguered U.S. frigate adrift to sink into the North Sea. Its final resting place has remained unknown ever since.

Over the next three weeks, the expedition will be conducted aboard Safeguard-class USNS Grasp. The team on deck will use survey data collected from remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs) equipped with side-scan sonar and multibeam echosounder equipment to investigate targets of interest gathered from previous surveys. The side-scan sonar and multibeam echosounder relay data to create an image of the sea floor using sound waves; if a particular target looks promising, archaeologists will investigate it more closely and, if possible, deploy divers to take an even closer look.
