- Finding
- The hull page lists a complement of 5 officers and 54 enlisted, accommodations for 2 officers and 46 enlisted troops, and a propulsion plant of two Fairbanks Morse model 38D81/8X10 reversible diesel engines with hydraulic clutches, direct drive, 1,440 BHP each at 720 rpm, twin propellers, and 2,800 shp; it also lists two diesel-drive 100-kW AC generators and one diesel-drive 20-kW DC generator.

[4]U.S. GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 [gao]

- Product-page description and highlights; full automated page fetch blocked HTTP 403
- Finding type
- gov_survey
- Finding
- GAO's HRD-80-2 product page describes a review of Navy efforts to protect workers from asbestos exposure, including Navy ship insulation, removal policy, and related program controls. This is Navy-wide program context for a hull built and operated during the documented asbestos-insulation era.

- Population
- Navy shipyard workers and Navy ships generally
- Limitations
- Program-level documentation, not hull-specific. It does not establish that asbestos was installed aboard LSM-53, identify a product or quantity, or establish exposure or causation. Full text was not retrieved because the direct page returned HTTP 403.

[5]Class/era inference based on NavSource's ship-specific diesel specifications and the GAO Navy asbestos-program context; source-review negative recorded in the search ledger [other_primary]
- Locator
- NavSource specifications block; GAO context row ev-04; search-ledger review
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, or condition report was located. Because LSM-53 was a World War II LSM-1-class landing ship with a documented diesel plant, machinery or diesel-exhaust insulation, gaskets, packing, electrical insulation, and deck covering are possible class/era application categories, but none is documented aboard this hull.

- Limitations
- Possible categories only, not a finding that asbestos was installed aboard LSM-53. The cited hull page does not identify asbestos or insulation composition; no quantity, exact location, condition, exposure, or causation is established.

[6]Source-review negative across the sources listed in the search ledger [other_primary]
- Locator
- Search-ledger rows sl-01 through sl-06
- Finding type
- historical_record
- Finding
- No ship-specific asbestos documentation was located in the public sources reviewed: the live hull page, GAO program page, NVR resource check, NARA fallback search, and official-source web search contained no asbestos survey, insulation-material statement, abatement record, hazmat disclosure, or product-identification record for LSM-53.

- Limitations
- A negative public-source finding is not proof that asbestos was absent. Firecrawl was blocked and NARA/NVR access was limited; non-digitized Navy, shipyard, barge-conversion, and disposal records may contain additional evidence. Asbestos documentation remains class_or_era.

- Finding type

- Finding
- The authenticated CourtListener API v4 exact-name opinion search for "USS LSM-53" returned zero hits. The remaining exact-name docket and exact-hull opinion/docket requests were not completed after the helper reported that the fleet-wide pacing budget was spent.
