- Finding type
- historical_record

- Finding
- After transporting oil on the East Coast and in the Pacific late in World War II, the tanker entered reserve at Olympia.

- Limitations
- Official NHHC text recovered through the search index; direct page retrieval returned no usable body. Verification is limited to the indexed text. This history is not an asbestos survey and establishes no material content or individual exposure. Corrects the prefix to USNS. The 1956 activation independently establishes Navy-associated service; no exact activation day or commissioning is asserted.
