The RCS Nimanoa was a wooden-hulled ketch, whereas Saidu Maru was a steel-hulled vessel, part of which is still visible on the reef off Red Beach. Unexploded artillery shells, mortar rounds, anti-aircraft shells and live machine gun bullets left over from the Second World War are littered throughout the island and surrounding reef, as well as the remains of several hundred U.S. and Japanese soldiers. The remains of 30 U.S. soldiers and Marines were discovered in March 2019. References South Tarawa
