190322-N-AP176-0178 ATLANTIC OCEAN (March 22, 2019) Boatswain's Mate 1st Class Andrew Johnson, left, assigned to Mobile Diving and Salvage Unit (MDSU) 2, discusses the Mark 18 Mod 2 unmanned underwater vehicle with Rear Adm. David Hahn, director of naval research, right, and Royal Navy Rear Adm. Hugh Beard, center, assistant chief of the naval staff (capability), aboard the Royal Fleet Auxiliary landing ship dock (RFA) Mounts Bay (L3008) during a mine countermeasures task group experiment. This experiment refines and advances the Navy explosive ordnance disposal (EOD) community's ability to command and control a mine countermeasures task group. The Navy EOD community achieves this by embarking vessels of opportunity to direct surface, air and expeditionary mine countermeasures forces, including the Navy's expeditionary mine countermeasures units.
