- DANFS USS LST-471 full entry
- Finding type
- vessel_history
- Finding
- DANFS states that LST-471 was laid down 29 October 1942 at Vancouver, Washington, by Kaiser, Inc.; launched 3 December 1942; and commissioned 11 March 1943 under Lt. Samuel C. Otto, USNR. It served in the Asiatic-Pacific theater in the Lae occupation, Leyte landings, Lingayen Gulf landing, Mindanao Island landings, and Balikpapan operation; was decommissioned 26 February 1946 and struck from the Navy list 12 April 1946; was sold to Hughes Bros., Inc., New York, on 21 January 1948; and earned five World War II battle stars.

- Limitations
- Authoritative service and disposition record; it contains no asbestos, insulation, hazardous-material, survey, or individual-exposure information. The source says the ship was subsequently scrapped, while NavSource gives a more specific account of loss during the tow; that later detail is carried separately and not upgraded into DANFS.

[3]NavSource Online, Amphibious Photo Archive, USS LST-471 [other_primary]
- Locator
- NavSource 160471: campaign chronology, disposition, specifications, and ship photographs
- Finding type
- vessel_history
- Finding
- The ship-specific archive identifies LST-471 as an LST-1-class tank landing ship, gives call sign NFYA, and records the Eastern New Guinea/Lae, Leyte, Luzon/Lingayen Gulf, Southern Philippines/Mindanao, and Borneo/Balikpapan operations. It gives five battle stars, decommissioning on 26 February 1946, striking on 12 April 1946, and sale for scrapping on 21 January 1948 to Hughes Brothers, Inc. It also lists two General Motors 12-567A 900-hp diesel engines, single Falk reduction gears, three diesel-drive 100-kW generators, twin propellers, a 13-officer/104-enlisted complement, and troop accommodations for 16 officers/147 enlisted.

- Volunteer-maintained archival compilation; its overlapping dates and service facts agree with DANFS. Equipment specifications establish a diesel propulsion arrangement, not asbestos content. The page does not provide a hazmat survey or asbestos inventory.

[4]NavSource ship-specific photo captions citing Australian War Memorial photographs and wreck photographs [other_primary]
- Locator
- NavSource 160471 photo-caption block: 1943 drydock and Rodanthe wreck photographs
- Finding type
- historical_record
- Finding
- NavSource captions identify a December 1943 drydock at Cockatoo Island Dock Yard, Sydney, to repair damage sustained during the 4 September 1943 Japanese aerial attack off Cape Ward Hunt, New Guinea. The archive also describes the post-sale tow failure: ex-LST-471 and ex-LST-292 were being towed together when the tow line parted during a storm; both beached near Rodanthe, North Carolina, and were deemed unsalvageable. The hulk later sank approximately 250 yards offshore in about 15 feet of water.

- Repair-yard workers in 1943; later tow/salvage workers
- Limitations
- The captions document a repair-period event and later wreck disposition, but do not identify asbestos or any particular insulation/product. The wreck description is an archival account; no independent hull survey, salvage report, or environmental record was located.

- Finding type
- asbestos_application
- Finding
- The study provides WWII shipbuilding-era context for asbestos-containing insulation, lagging, and gaskets. Applied only as class/era context to a 1942-43 diesel LST, potential material categories include diesel exhaust lagging, engine-room insulation, gaskets and packing, deck coverings, accommodation insulation, and brake linings.

- Population
- WWII-era U.S. shipbuilding and naval workforces
- Limitations
- The study does not name LST-471, Kaiser Vancouver, or this class and does not establish that any listed material was asbestos-containing aboard this hull. No ship-specific asbestos product is documented here; the diesel/no-boiler configuration limits the relevance of steam-boiler insulation pathways.

[6]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (1979) [gao]
- Locator
- GAO product page HRD-80-2; direct retrieval blocked (HTTP 403)
- Finding type
- gov_survey
- Finding
- GAO's Navy asbestos-program review is a fleet/shipyard context source for later asbestos-management practices, not a record about LST-471. The vessel had already been decommissioned, struck, and sold before the 1975/1979 policy period described in the batch's comparable records.

- The GAO product page returned HTTP 403 to direct automated retrieval on 2026-10-02; the citation remains a blocked access lead and this row does not rely on unverified full-text detail. It cannot establish any condition aboard LST-471.

- Finding type
- historical_record
- Finding
- The authenticated CourtListener search completed for the exact phrase USS LST-471 in opinions with zero returned results; the exact-name docket request was also issued. The helper then repeatedly stood down the remaining hull-number and asbestos-qualified requests under the fleet-wide pacing budget, so a complete negative sweep could not be certified in this session.

- A negative CourtListener result is not proof that no litigation exists. CourtListener coverage is limited by indexed opinions/dockets and does not establish the absence of state-court, sealed, unindexed, or non-digitized filings. No litigation-stage asbestos finding is carried.

[8]Batch research sweep: NHHC/DANFS, NavSource, NARA catalog, GAO, DOI-indexed era study, Firecrawl, and authenticated CourtListener [other_primary]

- Finding type

- Finding
- No qualifying ship-specific asbestos survey, abatement contract, hazmat disclosure, or direct product record was located in the searched public sources. The live NHHC URL returned 404, Firecrawl was quota-exhausted with a reported multi-hour wait, GAO direct retrieval returned 403, and NARA catalog search returned a JavaScript shell without a parseable LST-471 item result.

- This is a documented public-record search gap, not a finding that asbestos was absent. The 1943 construction era and diesel LST configuration support only class/era context; ship-specific asbestos presence, condition, quantity, and remaining material are unknown.
