- Live DANFS entry, service and disposition paragraphs
- Finding type
- vessel_history
- Finding
- The official DANFS entry states that during World War II LST-756 was assigned to the Asiatic-Pacific theater and participated in the assault and occupation of Iwo Jima in February 1945 and the assault and occupation of Okinawa Gunto in April through June 1945; that she returned to the United States and was decommissioned on 5 April 1946 and struck from the Navy list on 17 April that same year; and that on 19 September 1946 the ship was sold to the Construction Power & Merchandising Co., of Brooklyn, N.Y. DANFS credits LST-756 with two battle stars for World War II service.

- DANFS ends at the 1946 sale and does not trace the buyer's use or the hull's final fate; it does not identify materials aboard. It establishes service and administrative disposition only.

- NavSource's live LST-756 page records LST Flotilla Six (CAPT. Laidlaw), LST Group Eight flagship (CDR. P. Neikum, Jr.), and LST Division Thirty-Five assignments; campaign dates of the Iwo Jima assault and occupation, 19 to 25 February 1945, and Okinawa Gunto, 1 April to 30 June 1945; post-war occupation service in the Far East in the periods 6 to 23 September 1945, 1 to 21 January 1946, and 2 February to 1 March 1946; a six-officer succession list ending with Lt.j.g. Lymar D. Petersen, USNR (March 1946 to 5 April 1946); radio call sign NGGG; and final disposition 'sold, 19 September 1946, to Construction Power & Merchandising Co., Brooklyn, NY., fate unknown.'

- Limitations
- NavSource is an archival photo/history resource live-verified at research time. It supplies flotilla assignment, campaign-date, occupation-period, and command detail absent from DANFS; its page carries two typographical date slips ('8 August 1844' for the 1944 commissioning and a doubled '1944' at launch) that DANFS resolves. It does not document asbestos or individual exposure.

- Finding
- The contemporaneous Bureau of Ships publication Ships' Data, U.S. Naval Vessels, Vol. II (13 April 1945, NAVSHIPS 250-011) lists LST-756 with builder 'American Bridge Co., Ambridge, Pa.', keel laid 25 May 1944, launched 15 July 1944, and a 'date of first commission' entry of 29 July 1944; the volume's LST design table assigns the LST-542-931 hull group two G.M. 12-567A diesel engines totaling 1,700 brake horsepower.

- Limitations
- Contemporaneous official tabulation. Its 'date of first commission' of 29 July 1944 conflicts with the DANFS commissioning date of 8 August 1944 (Lt. Daum in command); DANFS is carried in the record fields and the variance is logged in gaps. The source confirms machinery type, not asbestos content, condition, exposure, or causation.

- asbestos_application
- Finding
- Era/design inference only: the BuShips LST design data identifies the LST-542-931 group as diesel-powered with two GM 12-567A engines and no boilers; period asbestos-relevant applications for this type may include diesel-engine and exhaust-system insulation, gaskets and packing, electrical insulation and cable, deck coverings, accommodation-space insulation, and brake/friction linings on winches and windlass.

[7]Batch-7290 source review and search ledger: live DANFS, NavSource LST-756 page, NARA Special List No. 44, BuShips Ships' Data 1945 Vol. II, authenticated CourtListener helper attempt, and secondary web sweeps [other_primary]

- Finding
- No qualifying ship-specific asbestos record was located in the public sources searched: the live DANFS entry and live NavSource page contain no asbestos, survey, abatement, hazmat, or insulation-material disclosure for LST-756; no CourtListener result was obtained because the authenticated helper reported the daily quota exhausted (approximately 11.5 hours to reset) before returning any result; and general web sweeps surfaced no qualifying litigation naming this hull.

- This is a negative finding about records located, not proof that asbestos was absent. CourtListener coverage is absent because the daily quota was exhausted before any search returned; no litigation conclusion should be drawn from the blocked requests.
