Source-derived summary

SS Mission San Luis Rey was a Type T2-SE-A2 tanker built for the United States Maritime Commission during World War II. After the war she was acquired by the United States Navy as USS Mission San Luis Rey (AO-128). Later the tanker transferred to the Military Sea Transportation Service as USNS Mission San Luis Rey (T-AO-128). She was a Mission Buenaventura-class oiler and was named for Mission San Luis Rey de Francia, located in Oceanside, California.

Career

Mission San Luis Rey was laid down 15 October 1943 under a United States Maritime Commission contract by Marine Ship Corporation, Sausalito, California; launched 29 January 1944; sponsored by Mrs. T. L. Phillips; and delivered 31 March 1944. Chartered to Pacific Tankers, Inc. for operations, she spent the remainder of the War carrying fuel to Allied bases overseas (during which time she was awarded the National Defense Service Medal). She served in this capacity until 29 March 1946 when she was returned to the Maritime Commission and laid up in the Maritime Reserve Fleet at James River, Virginia.

Acquired by the Navy 23 October 1947 she was placed in service with the Naval Transportation Service as Mission San Luis Rey (AO-128) and remained in this service until 1 October 1949 when she was transferred to the newly created Military Sea Transportation Service for duty as USNS Mission San Luis Rey (T-AO-128). She remained in this capacity until 6 May 1955 when she was returned to the Maritime Administration (MARAD) and laid up in the Maritime Reserve Fleet at Suisun Bay, California.

Editorial summary

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1943, 1944, 1946, 1947—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where USNS, Mission and Luis can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as wW II tanker. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Dec 12, 2025. The linked authority identifier is Q7866637. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1943, 1944, 1946 and 1947.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
