[2]DANFS, 'LST-1087' (NHHC): laid down 11 December 1944 at Ambridge, Pa., by the American Bridge Co.; launched 3 February 1945, sponsored by Mrs. Robert Maybin; commissioned 2 March 1945, Lt. H. C. Moses in command; occupation duty in the Far East and China service until early April 1947; decommissioned 11 August 1947; struck from the Navy list 29 September 1947; transferred 18 April 1948 to the United States Army for operation [nhhc_danfs]

Moses where NavSource's CO table shows LT Thomas R. Kieft USNR at commissioning 2-5 March 1945 then Moses; contains no asbestos, crew-exposure, or post-Army disposition information.

- The commanding officer's own wartime itinerary report: commissioned at New Orleans 2 March 1945; Pearl Harbor cargo run (departed 8 April, arrived 3 May 1945); Hilo lift of an artillery group (14-18 May); in convoy with 24 other LSTs to Eniwetok (anchored 5 June); orders changed Guam to Saipan (anchored 12 June); 69-ship convoy to Okinawa 8 July, Egushi Bay 14 July, unloaded 15 July; nightly smoke-making during red alerts 15-29 July with one typhoon sortie and a 24 July shift to Buckner Bay; 64-ship convoy to Saipan 29 July-8 August through a typhoon; Pearl Harbor 9-26 August; Sasebo occupation lift with 17 LSTs carrying an Engineer Pontoon Bridge Company (anchored Sasebo Bay 24 September, discharged 25 September); proceeded alone to Okinawa 1-4 October for repair of the port shaft bearing damaged while beaching at Sasebo.

- Catalog-level verification only: the catalog API returned this record once on 2026-10-02, then served a JS challenge to follow-up queries, so other war-diary months (the ship was in combat-zone service June-October 1945 and China service into 1947) could not be enumerated; diary images themselves were not read - image-level verification is open. Fold3 access is subscription-gated. Contains no known asbestos information.

[6]shipbuildinghistory.com (T. Colton), American Bridge Co. yard page, Ambridge PA: yard requisitioned by the Navy 1942 with $9M improvement investment; LST production table row 'LST 1087 | U.S. Navy | Landing Ship | 2-Mar-45 | Sold 1947 as Coos Bay' under official number 260599; yard returned to inland hopper barges postwar, closed 1981 [other_primary]

- American Bridge yard table, row for LST 1087 (ON 260599); yard-history paragraph
- Finding type
- vessel_history
- Finding
- The standard-compiled yard list names this hull and reports a post-Navy merchant sale as 'Coos Bay' (US official no. 260599), potentially resolving NavSource's 'fate unknown' - and supplies verified yard context: an inland requisitioned yard building ocean-going LSTs under wartime expansion.

- Limitations
- Secondary compiled reference (not official): the stated sale year 1947 conflicts with the documented April 1948 transfer to the U.S. Army (DANFS/NavSource) - plausibly the list compresses leaving government custody into a single dated sale event, or the Army resold the hull shortly after; official number 260599 was not verified against Merchant Vessels of the United States registers (not located in digitized form this session). Treat the merchant disposition as an open lead, not a finding.

[7]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (published Oct 18, 1979; publicly released Oct 22, 1979): GAO reviewed Navy asbestos-worker protection at Long Beach and Norfolk Naval Shipyards; Navy's 1975 policy removed/replaced only damaged or repair-disturbed asbestos insulation, modified 1979 to selective replacement in high-maintenance areas [gao]
- Locator
- GAO product page HRD-80-2, Highlights section
- Finding type
- gov_survey
- Finding
- Program-level documentation that the Navy used asbestos insulation aboard ships into the 1970s and managed it largely in place - establishing the era-policy frame within which a 1945-built hull would have carried era-standard asbestos materials. This hull left Navy custody in 1947-48, before the documented policy period.

[8]Consolidated era inference - NavSource specifications block for this hull (2 x GM 12-567A diesels, no boilers) + BuShips SD-1945 v2 design data for the LST-542 series + era amphibious-ship construction practice [other_primary]

- Class technical data; NavSource spec block
- Finding type
- asbestos_application
- Finding
- Era/design inference for a diesel-powered LST-542-class hull: no steam plant, so no boiler/turbine lagging pathway; asbestos-relevant applications for the type are GM diesel exhaust lagging and gaskets, engine-room thermal/acoustic insulation, deck coverings/tile, bulkhead and accommodation insulation, valve packing, and winch/crane brake linings.

- American Bridge Ambridge construction trades (1944-45); ship's company and embarked troops (1945-47); U.S. Army operators (1948 ff.); any later merchant/scrapping crews if the 'Coos Bay' disposition is confirmed
- Limitations
- Class/era inference only - no ship-level asbestos record was located for this hull or any LST-542 sister. Establishes no quantities, no specific product identification, and no individual exposure. The ship's short government career (1945-1948) means no documented asbestos-management-period yard work applies.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum record (ship is not extant), or docketed case naming LST-1087 was found in the public sources searched.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1945 wartime hull is era-consistent with asbestos materials. The 'USS LST-1087' opinion variant and a hull-specific NARA war-diary enumeration were left unsearched (fleet pacing throttle / JS challenge) - logged as blocked in the ledger, not as negative results. Does not establish or defeat any claim of exposure or legal eligibility.
