"Ironbottom Sound" (alternatively Iron Bottom Sound or Ironbottomed Sound or Iron Bottom Bay) is the name given by Allied sailors to the stretch of water at the southern end of The Slot between Guadalcanal, Savo Island, and Florida Island of the Solomon Islands, because of the dozens of ships and planes that sank there during the naval actions comprising the Battle of Guadalcanal during 1942–1943. Before the war, it was called Savo Sound. Every year on the battle's anniversary, a US ship cruises into the waters and drops a wreath to commemorate the men who lost their lives.[citation needed] For many Navy sailors, and those who served in the area during that time, the waters in this area are considered sacred, and strict silence is observed as ships cruise through.[citation needed]
Naval actions comprising the Battle of Guadalcanal

In September and October 1944, the wreck was used as a target for tests of the TDR-1 Drone by STAG-1 based at North Field on Banika, Russell Islands as part of the top secret project testing of America's first guided missile.
