Casualty Narrative
“The USNS Mission San Miguel, a T-2 type tanker of 10,461 gross tons, built in 1944, owned by the U.S. Navy, civilian manned and operated in the Military Sea Transportation Service, departed Guam, M. I. in ballast, on 1 October 1957 bound for Seattle, Washington, under U.S. Navy sailing orders which included positions to be traversed along a track passing through the Hawaiian Archipelago about 23 miles south of Maro Reef. In the evening of October 8 while proceeding at full speed - about 15 knots -weather overcast with rain squalls, the vessel struck this reef, piercing her bottom. Because of jammed valves, the cargo pumps were unusable to counteract the progressive flooding which followed through failure of pump room, engine room and cargo space bulkheads previously weakened by extensive wastage. On 10 October all personnel were removed by other U.S. Navy ships without injury or loss of life. The vessel valued at $2,000,000 was abandoned as a total loss.”
