- Finding
- LSM-482 was laid down at Brown Shipbuilding Co., Houston, Texas, on 17 February 1945; launched 10 March 1945; commissioned 10 April 1945 under LT Walter E. Keady, USNR; assigned during WWII to LSM Flotilla 15, LSM Group 44, LSM Division 87; and decommissioned and transferred to the Republic of China on 8 May 1946. NavSource reports Communist seizure in October 1949, reported PRC Navy activity circa 1996, and an unknown final disposition. Its specification block gives two GM 16-278A direct-drive diesel engines, 1,440 BHP each, and no boiler plant.

- Limitations
- A secondary archival compilation, not a Navy material survey or work package. It establishes the reported history and published specification, but does not establish asbestos content, quantity, condition, individual exposure, causation, or the vessel's present location.

- Finding
- NARA catalogs a digitized RG 24 muster-roll file unit for LSM-482 covering 10 April 1945 through 8 May 1946, with 154 images. The file is a hull-specific personnel-record lead spanning the commissioned U.S. Navy career.

- Finding type
- historical_record
- Finding
- No individual DANFS narrative was located for LSM-482. The archived NHHC appendix explains that numbered LSM/LSM(R) craft were excluded from DANFS because they lacked assigned names and identifies a compiled LSM/LSM(R) history (CD-ROM SH-0068) as the substitute source.

- GAO product page HRD-80-2, Highlights
- Finding type
- gov_survey
- Finding
- GAO reviewed Navy asbestos-exposure protections, including asbestos use in Navy ships, removal costs, and compensation programs. It describes the Navy's 1975 policy to remove and replace nonasbestos material only when insulation was damaged or removed for repair, and the 1979 selective-replacement policy for high-maintenance areas.

- Limitations
- Navy-wide program documentation, not a record for LSM-482; the review's fieldwork was at Long Beach and Norfolk naval shipyards, not Brown Shipbuilding. It does not establish material aboard this hull, present condition, exposure, or causation. The GAO full PDF was not extracted in this resumed session.

- Locator
- NavSource Specifications; historical sources identified in ev-04 and ev-05
- Finding type
- asbestos_application
- Finding
- A 1945 direct-drive diesel landing ship falls within the documented WWII shipbuilding asbestos-use era. Possible era-standard applications on this type include engine-room thermal insulation, diesel-exhaust lagging, flange and machinery gaskets, valve packing, deck coverings, and accommodation insulation. The NavSource specification identifies a diesel plant rather than a boiler plant.

- Finding type

- Finding
- No qualifying asbestos litigation is documented by the completed portion of the CourtListener sweep. The prior session's authenticated exact-name opinions search for USS LSM-482 returned count=0. In the resumed session, the required exact hull-number opinion search was stopped by the fleet pacing limiter before it returned; the remaining exact-name/hull opinion and docket queries were not completed rather than retried outside the limiter.
