    Sioux 108k USNS Sioux (T-ATF-171) tows the Royal Canadian Navy replenishment oiler HMCS Protecteur (AOR-509), on 5 March 2014. Protecteur suffered a fire and breakdown 340 nautical miles northeast of Pearl Harbor, Hawaii. She was moving at limited speeds and the U.S. Navy ships USS Michael Murphy (DDG-112), USS Chosin (CG-65) and USNS Sioux (T-ATF-171) were dispatched to assist, with the Sioux later towing Protecteur to Hawaii after Chosinīs tow line parted.
