- Finding
- The official DANFS entry states that LST-770 served in the Asiatic-Pacific theater and participated in the assault and occupation of Okinawa Gunto from March through June 1945; performed Far East occupation duty until late October 1945; was decommissioned on 29 April 1946; struck from the Navy list on 31 July 1946; and sold on 6 February 1948 to Madison B. Wright for non-self-propelled operation. DANFS credits one World War II battle star.

- historical_record
- Finding
- NARA Special List No. 44, by ship number, lists LST-770 with U.S. Coast Guard logbook coverage from 13 October 1944 through 30 June 1945, providing an archival lead spanning commissioning and the Okinawa-period record.

- Limitations
- The index confirms logbook coverage dates, not the contents of the logs. No logbook volume was retrieved, so this row makes no asbestos or exposure finding.

- Locator
- PDF p. 2, Enclosure I, response to question 3
- Finding type
- asbestos_application
- Finding
- The GAO report on Navy efforts to protect workers from asbestos exposure states that Navy ship weight-control reports can provide ship-specific quantities of asbestos thermal insulation and separately identifies other applications such as pipe-hanger liners and gaskets. It also states that replacement decisions were made on an individual ship or ship-class basis.

[5]National Archives, Researching Asbestos aboard US Naval Vessel up through 1961 [other_primary]
- Locator
- Beginning Research; Volumes; Historical Notes and Other Specifications and Standards Series
- Finding type
- historical_record
- Finding
- NARA's research guide explains that documenting asbestos aboard a particular naval vessel requires ship-specific records such as engineering drawings and cautions that sister ships built at different yards may differ in materials or subcontractors. The guide identifies Navy ship specifications and engineering records as relevant archival paths.

- Limitations
- This is a research guide, not evidence that asbestos was aboard LST-770. It identifies the records needed to resolve the hull-specific question and does not establish any material, exposure, or legal conclusion.

[7]Batch-7306 source review: NHHC DANFS, NARA Special List No. 44, NARA asbestos research guide, and GAO HRD-80-2 [other_primary]
- Locator
- Search ledger rows sl-uss-lst-770-lst770-01 through -09
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located in the authoritative sources reviewed: the official DANFS entry, NARA logbook index, and NARA asbestos research guide contain no LST-770 asbestos survey, abatement contract, hazmat disclosure, material schedule, or insulation statement. The GAO report is general Navy program evidence and does not name this hull.

- Limitations
- This is a finding about records located, not proof that asbestos was absent. CourtListener coverage is incomplete because the authenticated helper returned a fleet pacing stand-down before the exact-name and hull-number searches could be completed; no litigation conclusion is drawn.
