- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - milestone dates corroborate DANFS exactly. The 'surgically equipped' detail rests on a contributor-supplied photo caption (PHom1/c Ken Kracht collection), not an official LST(H) designation; no such designation appears in DANFS or the page header.

- Finding type
- historical_record
- Finding
- Eight NARA file units for this hull are digitized and readable online (Fold3 scans). Sampled pages verified: the commissioning-to-August-1944 war diary records the ship's transit downriver and shakedown - 26 May 1944 underway from Quarantine Anchorage, New Orleans, LA, en route St. Andrews Bay, Florida, on shakedown cruise; anchored St. Andrews Bay 27-30 May conducting tactical exercises (one auxiliary-engine fuel-suction casualty logged 30 May). The Sadau/Tarakan report file includes a hand-drawn loading diagram captioned 'USS LST 667' showing main-deck and tank-deck vehicle/LVT stowage. These primary documents confirm the operational record in DANFS/NavSource and are the open lead for any crew-strength, embarked-unit, or material detail.

- Operational records - they document movements and actions, not material composition; no asbestos content found in sampled pages and none expected in this record type. Sampled, not exhaustively read (the Tarakan-action surgical-fit claim in ev-02 could be corroborated or corrected by full reading of NAIDs 139998116/101768494). Catalog search 'LST-667' also returns loosely-matched file units of other vessels; the eight listed here are titled for this hull.

[5]Era inference built on: NavSource specifications for this hull (2 x GM 12-567A 900-hp diesels, Falk reduction gear, 1,700 shp - diesel plant, no boilers); Bureau of Ships, Ships' Data U.S. Naval Vessels 1945 Vol. 2, LST design table (shipscribe scan, live URL verified 2026-10-02; the file moved from the formerly-cited /styles/usnaux/sdb/ path, now 404); LST-542-group membership per BuShips design grouping carried in the lst-1-class Atlas profile [other_primary]

- Finding type
- asbestos_application
- Finding
- A diesel-powered tank landing ship built February-May 1944 sits inside the Navy's documented asbestos-use era. Asbestos-relevant applications for a ship of this type and period were diesel-exhaust and engine-room lagging, machinery gaskets and valve packing, thermal/acoustic insulation, deck coverings/tile, accommodation insulation, and winch/crane brake linings. Because LST-667 carried a diesel plant with no boilers, the boiler/steam-line lagging pathway that dominates steamship exposure narratives does not apply; the relevant pathways aboard were machinery-space insulation and interior fitted materials.

- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire construction (1944) and service era (1944-46).

- Finding type
- historical_record
- Finding
- The builder's corporate archive documents the yard context for this hull's construction: 100% of American Bridge's capacity went to national-defense projects 1941-1945; the company manufactured 199 LSTs at Ambridge, PA; LST assembly crews worked at the Employee Gardens south of the AB plant in Leetsdale, PA; peak employment approached 13,000, with crews working 364 days a year. The archive also notes (class-level) that LSTs served as makeshift hospitals, repair facilities, and supply ships - general corroboration of the casualty-reception role this hull's photos show at Tarakan.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or litigation naming USS LST-667 (hull never named, so hull-number sweeps are exhaustive) was found in the public sources searched. CourtListener returned zero results for "LST-667" and "LST 667" in both the opinion (type=o) and docket (type=r) indexes on 2026-10-02. Secondary web sweeps surfaced only law-firm marketing listicles (mesotheliomahope.com, swmwlaw.com, asbestos-ships.com and similar 'ships with asbestos' databases) asserting asbestos aboard era vessels without primary sourcing - excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - asbestos presence remains a reasonable era-consistent inference for a 1944 naval auxiliary, not a ship-proven fact. The hull's pre-regulation disposal (1947-48) left no environmental record to find. Deck logs (RG 24) and any builder material records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
