The U.S. Military Sealift Command fleet ocean tug USNS "Sioux" (T-ATF-171) tows the Royal Canadian Navy replenishment oiler HMCS "Protecteur" (AOR 509). "Protecteur" suffered a fire and breakdown 340 nautical miles northeast of Pearl Harbor, Hawaii (USA). She was moving at limited speeds and the U.S. Navy ships USS "Michael Murphy" (DDG-112), "Chosin", and USNS "Sioux" (T-ATF-171) were dispatched to assist, with the "Sioux" later towing "Protecteur" to Hawaii after "Chosin"´s rope broke.
