# Savo Island order of battle

The Battle of Savo Island was part of Guadalcanal Campaign and was fought on 9 August 1942 in the waters around Savo Island by forces of the Imperial Japanese Navy (IJN) and Allies' Guadalcanal—Tulagi invasion force composed of ships from the United States Navy (USN) and Royal Australian Navy (RAN). The battle resulted in a major Allied defeat, losing four heavy cruisers. The Japanese lost no ships but failed to capitalize on the temporary strategic advantage gained from the battle, leaving the unprotected Allied transports unharmed.
Because the Japanese had the tactical initiative, their forces are listed first.
