The Prometheus class were former colliers converted to repair ships in 1913-1914. The two ships were not strictly sister ships, but were similar enough that they are sometimes listed as such, as we have done here.

The Vestal was moored alongside the Arizona when the Japanese attacked Pearl Harbor, and she took two bomb hits as well as considerable damage from the Arizona magazine explosion. Her captain beached her to prevent her from sinking, and she was repaired for service throughout the war, giving particularly crucial service during the South Pacific campaign of 1942-1943.
