[5]History of LST Flotilla Seven (period U.S. Navy unit history, compiled by Lt.(jg) Phineas Stevens; contributed by Guy G. Guthridge; NavSource-hosted scan): LST-170 listed among the flotilla's originally assigned ships; named at the Saidor initial landing (2 January 1944); in the Cape Sansapor echelon departed Maffin Bay 27 July 1944, unloaded 30 July; in the 15 February 1945 Leyte-to-Finschhafen/Hollandia resupply movement for Mindoro/Manila echelons; and in the 14 April 1945 departure from Mindoro for the Illana Bay, Mindanao, initial assault landings 17 April 1945 [other_primary]

- Finding type
- historical_record
- Finding
- Period Navy flotilla history (written 1946 at war's end) names LST-170 in the original flotilla assignment and in four dated operations: Saidor 2 Jan 1944; Cape Sansapor 27-30 Jul 1944; the Feb 1945 Philippines resupply staging; and the Illana Bay assault echelon 14-17 Apr 1945. The same history records damage to LSTs 171, 181, 452, 456, 66 (suicide-plane strike), and 473 - LST-170 is not among hulls recorded as damaged, and the flotilla lost no ship.

- Unit-level period document - corroborates operational presence, not materials conditions. Contains no asbestos content. OCR of the scanned document is imperfect ('LST 170?' renderings); all four LST-170 mentions verified in context. Absence from the flotilla's damaged-ship lists does not prove the hull was never damaged - only that the unit history does not record it.

[8]Era inference built on: BuShips SDB 1945 v2 machinery/design data for the LST-1-490 group (diesel plant, no boilers); mass production 1942-1945 across 17 yards incl. inland 'cornfield' yards (Missouri Valley Bridge & Iron, Evansville, is this hull's builder per DANFS/SDB roster); standard U.S. naval construction practice of the era used asbestos-containing thermal insulation, gaskets, packing, and deck coverings [other_primary]

- Finding type
- asbestos_application
- Finding
- Era-consistent asbestos applications for a 1942-43 diesel-powered amphibious auxiliary of this design: engine and exhaust-system lagging; machinery gaskets and valve packing; thermal insulation in accommodation and messing spaces; deck coverings and tile; electrical insulation; brake linings on winches, windlass, and bow-door/ramp machinery. The diesel plant (no boilers, no steam drums) removes the boiler-lagging pathway typical of steam auxiliaries but leaves machinery-space and accommodation pathways.
