- 1976 operational narrative, Subic Bay to Guam tow paragraph
- Finding type
- vessel_history

- Limitations
- Establishes the YTM designation and this tow only. Being towed does not by itself establish Kittaton's operating status, reason for tow, repair activity, or asbestos presence. This 1976 Guam visit does not document the stated 1945 Guam service.

- PDF page 105, YTM 0406 row; search-indexed text (direct PDF fetch returned HTTP 403)
- Finding type
- vessel_history
- Finding
- NAVSEA's inactive-ships history table lists hull YTM 0406 as KITTATON, gives a removal date of 1 July 1987, and records the final disposition category as SCRAP SALE.

- Limitations
- The Navy search index exposes this row, but the PDF could not be opened directly in this environment. 'Removal' is not automatically the out-of-service or stricken date, and 'SCRAP SALE' does not prove physical scrapping or exclude later private use. Date and disposition should be rechecked against the original PDF or NVR before publication.

- PDF page 20, printed page 11, Large Harbor Tug - YTB table; PDF page 10, Navy letter scope
- Finding type
- asbestos_application
- Finding
- A Navy response reproduced in GAO report HRD-80-2 identifies asbestos thermal insulation for a group of large harbor tugs, YTB-817 through YTB-826, built in the 1970s. Kittaton (YTB-406) is not in the table.

- 1972-1975 construction; 1979 Navy submission
- Population
- 1970s large-harbor-tug construction and maintenance personnel, not Kittaton personnel
- Limitations
- Different harbor-tug hulls delivered decades after Kittaton; neither a Sassaba-class specification nor a finding about YTB-406. It cannot establish asbestos aboard Kittaton, a product there, quantity, location, individual exposure, or causation. The table is useful only to prioritize a hull-specific records search.

[6]Batch-9376 search ledger: NHHC 1945 roster, Navy photograph 80-G-428659, Beaufort DANFS history, NAVSEA inactive-ships index, NARA asbestos research guide, and CourtListener helper attempt [other_primary]

- search_ledger rows sl-uss-kittaton-yt406-01 through sl-uss-kittaton-yt406-08
- Finding type
- historical_record
- Finding
- No Kittaton-specific asbestos survey, material specification, abatement record, or asbestos case was established by the public sources completed in this batch. Authenticated CourtListener exact-name opinion and docket indexes returned zero hits, but hull-number searches remain incomplete because the fleet pacing gate denied the next request.

- Limitations
- The incomplete hull-number litigation sweep and unretrieved construction/repair files limit this negative finding. Zero indexed exact-name hits do not prove absence of litigation elsewhere, asbestos aboard Kittaton, or exposure; the row establishes no causation or legal eligibility.

- Beginning Research / Bureau of Ships correspondence; Cartographic Branch / Ship Engineering Drawings
- Finding type
- historical_record
- Finding
- NARA identifies RG 19 Bureau of Ships correspondence and ship engineering drawings as principal sources for vessel-specific asbestos research. It directs researchers to hull-specific files and S39 insulation-and-lagging, S48 piping, and S103 general-plan drawings. Kittaton's YTB-406 and YTM-406 files are the next archival targets; they were not retrieved for this batch.
