- Finding
- Documented for this hull: laid down 10 July 1942 at Vancouver, Wash., by Kaiser, Inc.; launched 20 October 1942; commissioned 3 February 1943, Lt. Asa L. Perdue, USNR, in command. Assigned to the Asiatic-Pacific theater: Eastern New Guinea (Lae Sep 1943, Saidor Jan-Feb 1944), Bismarck Archipelago (Cape Gloucester Dec 1943-Mar 1944, Admiralty Islands Mar 1944), Hollandia (Apr 1944), Western New Guinea (Toem-Wakde-Sarmi May 1944, Biak May-Jun 1944, Cape Sansapor Jul-Aug 1944, Morotai Sep 1944), Leyte (Oct 1944), Lingayen Gulf (Jan 1945), Mindanao (Apr 1945), Balikpapan (Jun-Jul 1945). Occupation duty in the Far East until early February 1946; served MSTS as USNS LST-456 from 31 March 1952; struck from the Navy list 15 June 1973; sold 27 September 1973 to the Maritime Co. Ltd., Khorramshahr, Iran. Earned eight battle stars for World War II service.

- Limitations
- Ship-specific history only; contains no asbestos or material content. DANFS does not record the 5 February 1946 decommissioning or the SCAJAP Q043 designation - those come from NavSource (ev-02). DANFS '10 July 1942' laid-down date conflicts with the Kaiser yard table's 3 August 1942 (see gaps). DANFS page verified live via Firecrawl 2026-10-02 (plain curl fetch of the same URL returned 404 - a server quirk, not link rot).

- NavSource timeline for this hull: laid down 10 July 1942 at Kaiser, Inc., Vancouver, WA; launched 20 October 1942; commissioned USS LST-456 3 February 1943, LT. Asa L. Perdue, USNR, in command; assigned to the Asiatic-Pacific Theater with the same campaign set as DANFS plus per-campaign date ranges; occupation service in the Far East 14 January - 5 February 1946; decommissioned 5 February 1946 and assigned to COMNAVFE Shipping Control Authority for Japan (SCAJAP), redesignated Q043; transferred 31 March 1952 to MSTS and placed in service as USNS T-LST-456; struck from the Naval Register 15 June 1973; sold 27 September 1973 to the Maritime Co. Ltd., Khorramshahr, Iran, renamed MV Karkas (Iranian flag); sold 1 February 1993 to Al Jazya Mar. y Sh. Ag. (UAE), renamed MV Bshair under Bolivian flag; deleted from the Bolivian register, date and fate unknown. Photo captions document three Japanese bomb hits (all duds) during the Biak operation May 1944 and one Silver Star / four Bronze Stars awarded for ordnance disposal; a full commanding-officer list (7 COs, Feb 1943 - Feb 1946) is published. Spec block: 1,625 t light / 4,080 t full load, 328 ft oa, 50 ft beam, 11.6 kt trial, 2 GM 12-567A diesels 900 hp each, Falk reduction gears, 2 shafts 1,700 shp, 3 x 100 kW diesel generators; complement 13 officers / 104 enlisted; troop accommodations 16 officers / 147 enlisted.

- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - its milestones generally track DANFS/NVR but SCAJAP/Q043 details and the merchant chain (Karkas, Bshair) rest on its compilation alone. Contains no asbestos content. The 1973 foreign sale and 1993 resale predate/dodge modern ACM-handling regimes; no hazmat record for the merchant conversions was located.

- shipbuildinghistory.com Kaiser Vancouver page, yard hull table row 160
- Finding type
- vessel_history
- Finding
- The Kaiser Vancouver construction table lists yard hull 160 as LST-456, MC hull 976: keel laying 3 August 1942, launch 20 October 1942, delivery 3 February 1943 (78 days on the ways, 105 in water, 183 total); disposition 'To MSTS 1952, sold private 1973, disposition unknown.' The table sits in a Kaiser Vancouver yard block built on USMC contract with 10 ways (expanded to 12), closed at war's end and sold to Gilmore Steel in the 1950s.

- Keel date CONFLICTS with DANFS (10 July 1942 vs 3 August 1942 - 24 days); DANFS date carried in the record, the conflict logged in gaps. Yard table is a Maritime Commission records compilation (secondary, but MC-derived); launch and delivery dates agree with DANFS. No asbestos content; 'sold private 1973' is consistent with but less specific than DANFS's named Iranian buyer.

[5]NARA RG 38 (Office of Naval Records and Library) holdings for this hull: USS LST-456 War History (NAID 77707256, Roll A2107, 11 images) plus a run of monthly War Diary file units (e.g., NAID 78225175 Sep 1943, 78269033 Oct 1943, 78299840 Nov 1943, 78382281 Jan 1944, 139757470 Sep 1944 - ~600 catalog results under the hull phrase) and still photos naming the hull (NAID 205585642 'The Yankees Come Back to Luzon,' 26-G-3859, Lingayen 9 Jan 1945; SC 259917 at Finschhafen per NavSource captions) [other_primary]

- Finding type
- historical_record
- Finding
- NARA's catalog returns an unusually complete documentary run for this hull: a compiled War History (11 microfilm images) and month-by-month War Diaries across her 1943-1945 commissioned service, all digitized on the WWII War Diaries microfilm series. These are the primary operational records for a material-level investigation - a war diary records where the ship was and what damage/refit it took, but does not itemize construction materials.

- Archival lead only: the diaries' content was not read page-by-page this session; they are unlikely to state asbestos content directly but are the correct venue for damage/repair events that drive insulation disturbance (e.g., the May 1944 Biak bomb hits documented by NavSource captions). No asbestos content in the catalog metadata itself.

[6]Bureau of Ships, Ships' Data, U.S. Naval Vessels, Vol. 2 (Jan 1945), LST design table - consolidated with the LST-1-class profile era inference [other_primary]

- Finding type
- asbestos_application
- Finding
- An LST-1-class hull built in 1942 sits inside the wartime asbestos era. The BuShips design table confirms the type's machinery: 328 ft oa, 50 ft beam, 2 GM 12-567A diesels ~1,700 shp, 11.6 kt - a diesel plant with no boilers, so the boiler/steam-turbine lagging pathway of steam combatants does not apply. Era-standard asbestos-relevant applications for the type were diesel exhaust lagging and gaskets, engine-room thermal/acoustic insulation, deck coverings and tile, bulkhead and accommodation insulation, and winch/crane brake linings.

[7]NARA, 'Researching Asbestos aboard US Naval Vessel up through 1961' - official research guide identifying RG 19 Bureau of Ships correspondence (filed by hull designation, e.g. LST456) and deck logs as the repositories for ship-level asbestos documentation [other_primary]

- Finding type
- historical_record
- Finding
- NARA's own guided-research page states that documenting whether a particular US naval ship carried asbestos requires RG 19 Bureau of Ships correspondence (1940-1961, filed by Navy Filing Manual codes - this hull would file under 'LST456,' with class fallback to 'LST1 Class' and type fallback to 'LST'), the builder's yard correspondence (private yards filed under 'QM/<name>'), and ship deck logs. These RG 19 series for LST-456 and Kaiser Vancouver are undigitized - the material-level record for this hull is an open archival lead, not a negative.

- Finding type
- historical_record
- Finding
- The Atlas yard dataset carries Kaiser Shipyards as a tier-3 asbestos-documented organization with 'Vancouver Shipyard' among its aliases - but the underlying ACM documentation (DTSC Richmond Harbor restoration; EPA CERCLA record) pertains to the Richmond, CA complex, not the Vancouver, WA ways where this hull was built. The Vancouver yard itself has no located ACM record in the dataset.

[9]Batch-6959 search ledger (this record): live NHHC DANFS page; NavSource 10/16/160456; Kaiser Vancouver yard table; NARA catalog (war diaries, war history, still photos); NARA asbestos research guide; CourtListener API v4 opinion index (4 phrase queries); docket index (partially throttled); secondary web asbestos sweep [other_primary]

- Finding
- No qualifying ship-specific asbestos record located: no insulation survey, abatement contract, hazmat disclosure, or docketed litigation naming LST-456 / T-LST-456 / Q043 / Karkas was found in the public sources searched. CourtListener opinion index returned zero hits for each of '"LST-456"', '"USS LST-456"', '"T-LST-456"', and '"LST 456"' (authenticated API v4, 2026-10-02). CAVEAT: the CourtListener docket (RECAP) index query was blocked by fleet-wide pacing mid-session - logged as blocked, not a negative result; the opinion index result stands. Secondary web sweeps surfaced only law-firm listicles asserting class-generic asbestos aboard 'all pre-1980s Navy ships' without primary sourcing - excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - the hull was built in the wartime asbestos era and the correct repositories (RG 19 correspondence, deck logs, SCAJAP/MSTS maintenance files) are undigitized. Does not establish or defeat any claim of exposure or legal eligibility. The foreign merchant career (1973-1990s Iran/UAE/Bolivia) generated no accessible hazmat record.
