[4]Bureau of Ships, Navy Department, Ships' Data, U.S. Naval Vessels, Vol. II, NAVSHIPS 250-011 (15 Apr. 1945), LST1-490 design-group characteristics and machinery tables; official publication scan. [other_primary]

- Finding type
- historical_record
- Finding
- The official Bureau of Ships LST1-490 design-group table specifies two General Motors 12-567A diesel engines, 1,700 horsepower, 11.6 knots, a single Falk reduction gear, two shafts, and three 100 kW 230-volt DC diesel-driven ship-service generators. It lists design accommodations of 13 officers and 106 enlisted.

- Design-group data, not a construction record or inspection of LST-172. It supports the diesel/no-boiler design description and design accommodations only; it does not establish the actual crew figure, installed materials, asbestos presence, quantity, condition, exposure, or causation aboard this hull.

- Finding type
- historical_record
- Finding
- National Park Service builder-yard context: the Navy built Evansville Shipyard on 40 acres on Evansville's west side; Missouri Valley Bridge and Iron began producing its first LST within four months of the February 1942 announcement. By February 1945, the yard had produced 167 LSTs, and a January 1946 fire destroyed the yard.

- GAO product-page Highlights; official full report PDF is https://www.gao.gov/assets/hrd-80-2.pdf.
- Finding type
- gov_survey
- Finding
- GAO's 1979 Navy-wide review examined the use of asbestos in Navy ships, removal costs, and compensation programs. Its highlights describe the Navy's 1975 policy to replace only damaged or repair-removed asbestos insulation, modified in 1979 to selectively replace asbestos insulation in high-maintenance areas.

- Population
- Navy shipyard workers and Navy ship maintenance program
- Limitations
- Program-level evidence from a review centered on Long Beach and Norfolk naval shipyards, not LST-172 or Evansville. It documents Navy asbestos policy and shipboard asbestos as an era-level subject, not a hull-specific installation, quantity, condition, exposure, or causation. The product endpoint returned HTTP 403 to direct fetch, but the official GAO page and PDF were live and independently retrievable through the research browser on the access date.

[7]Conservative synthesis of the Bureau of Ships LST1-490 design-group machinery table and GAO HRD-80-2 Navy-wide asbestos-program review; no hull-specific asbestos document located. [other_primary]

- Finding type
- asbestos_application
- Finding
- Class/era inference only: LST-172's documented LST1-490 diesel design has no boiler or steam-distribution plant, so a boiler-room or steam-line lagging pathway is not supported. GAO's Navy-wide review establishes that shipboard asbestos insulation was an era-level subject, but no source reviewed identifies any asbestos-containing product or application aboard LST-172.

- Inference only. It does not establish that asbestos was present or absent aboard LST-172, name a product or manufacturer, quantify material, establish condition, identify an exposure pathway for any person, or establish causation.

[8]National Archives, 'Navy Deck Logs Available in the National Archives Catalog.' [other_primary]
- Locator
- Introductory text on deck-log purpose, digitization, and Archives II contact for logs not on the online list.
- Finding type
- historical_record
- Finding
- NARA states that Navy deck logs are chronological accounts of notable events and are being digitized in batches; for logs not displayed in its online list, it directs researchers to Archives II textual-reference staff. LST-172's indexed 1943-1945 log coverage is therefore an open archival lead for operational and maintenance records.

[9]Batch 6731 search ledger: official BuShips, NARA, NPS, GAO, NHHC/NVR checks, authenticated CourtListener helper, and Firecrawl access attempt. [other_primary]
- Locator
- search_ledger rows sl-uss-lst-172-01 through sl-uss-lst-172-09.
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located in the authoritative sources searched: no asbestos survey, material schedule, abatement contract, or hazmat disclosure was found. Authenticated CourtListener searches of the exact name "USS LST-172" returned zero results in both the opinion and docket indexes. The hull-number "LST-172" opinion and docket searches could not be completed because the fleet helper reported a momentarily exhausted shared pacing budget; this is an incomplete litigation result, not a no-result finding.

- Study period

- Limitations
- A negative public-source search does not prove asbestos was absent. Exact-name CourtListener opinion and docket searches returned zero results, but the hull-number opinion and docket requests were stood down by the authenticated fleet helper; the litigation sweep is therefore incomplete. No litigation disposition, exposure evidence, or legal eligibility conclusion is made. Firecrawl was also unavailable because its keyless quota was exhausted.
