[4]Navy Department, Office of the Chief of Naval Operations, Ser. 95223, 'Ocean-Going Tugs and Harbor Tugs – Recommendations for reclassification of,' 13 April 1944, with Secretary of the Navy approval endorsement (transcription) [other_primary]
- Locator
- Paragraph 3, effective date; ATR-98 → ATA-171 table row; first endorsement approving recommendations
- Finding type
- historical_record
- Finding
- A Navy reclassification document dated 13 April 1944 lists ATR-98 for redesignation as ATA-171, effective 15 May 1944. ATR-98 had already been lost on 12 April; ATA-171 was therefore a prospective designation rather than an operational identity.

- Limitations
- Primary Navy document is available here as a third-party transcription, not an inspected archival image. The conclusion about non-effective redesignation follows the documented loss date and later effective date. NARA also indexes a plan under ATA-171; an archival label does not show the lost vessel served under it. No asbestos information.

- The accessible text is a transcription of an official Navy chronology, not an inspected original image. It establishes the reported collision partner and approximate location; it does not provide an investigation, casualty count, material composition, or exposure evidence. The Navy's wartime loss report rounds the latitude to 44°05′N.
