USS San Francisco (CL/CA-38), a New Orleans-class cruiser, was the second ship of three of the United States Navy named after the city of San Francisco, California. Commissioned in 1934, she was one of the most decorated ships of World War II, earning 17 battle stars and the Presidential Unit Citation.

The Battle of Cape Esperance, also known as the Second Battle of Savo Island and in Japanese sources as the Sea Battle of Savo Island (サボ島沖海戦), took place on 11–12 October 1942, in the Pacific campaign of World War II between the Imperial Japanese Navy and United States Navy. The naval battle was the second of four major surface engagements during the Guadalcanal campaign and took place at the entrance to the strait between Savo Island and Guadalcanal in the Solomon Islands. Cape Esperance (9°15′S 159°42′E) is the northernmost point on Guadalcanal, and the battle took its name from this point.
