HMAS HOBART was torpedoed by the Japanese submarine I-G011, while steaming to Espiritu Santo in the New Hebrides. The torpedo struck aft on the port side causing considerable damage in the vicinity of the wardroom. Thirteen officers and sailors were killed and another seven injured. She made it to Espiritu Santo under her own power the following day where she underwent temporary repairs and was escorted to Sydney by HMA Ships Warramunga and Arunta. She arrived on 26 August for extensive repairs which kept her out of service until December 1944. The torpedo which struck HOBART was fired at a range of 10 miles.
