    486k USS YP-346 aground near Tulagi Harbor, Tulagi Island, Solomon Islands, 09 September 1942. Hours before, just after midnight, she was shelled by the IJN light cruiser Sendai and three destroyers (Shikinami, Fubuki and Suzukaze) as she approached the harbor of Tulagi. The first salvo struck astern and started a fire aft. Anti-aircraft bursts subsequently struck amidships, destroying the life boats. Several near misses and one shell struck the pilot house on the port side, damaging the steering and engine room controls and hampering maneuverability. With great effort, YP-346 was beached with the intent of salvaging as much equipment as possible and saving the crew. One man was lost on the boat. Late that evening, Sendai returned and shelled the beached "Yippie," completely destroying her.
