- Ship-specific official history; contains no asbestos information. DANFS renders the redesignated hull as 'LSTH-950' (NavSource/NVR style: LST(H)-950). The Bikini Atoll evacuation and flotilla/group assignments rest on NavSource, not this entry.

- Finding
- Official BuShips roster row for this hull: keel laid 1 September 1944, launched 4 October 1944, first commissioned 27 October 1944, builder column 'Bethlehem Steel Co., Hingham, Mass.' (ditto chain). The companion design table assigns hull block LST-932 through LST-979 - which includes this hull - two General Motors 12-278A diesels at 1,700 shaft horsepower, two shafts; block dimensions 328 ft oa x 50 ft, 2,366 t light / 4,080 t trial, 11.6 kt, accommodations 13 officers/106 enlisted.

- Limitations
- The roster row names this specific hull; the machinery figure is a block-level assignment (LST-932-979), not a hull-specific machinery record. Conflicts with NavSource's generic spec block, which lists GM 12-567A engines (see gaps). BuShips 'accommodations' is berthing capacity, not the ship's complement. No asbestos content.

- Hull-specific compilation: commissioned 27 October 1944 under LT. Fritz W. Heim, USN; assigned to LST Flotilla Twenty-Five (CAPT. H.E. Richter), LST Group Seventy-Five (CDR. G.W. Stringer), LST Division One Hundred Forty-Nine; Okinawa Gunto operation 1 April-18 June 1945; redesignated LST(H)-950 15 September 1945; occupation duty 21 October-5 November 1945; assisted evacuation of Bikini Atoll natives prior to atomic bomb testing; decommissioned 23 September 1946; struck 10 June 1947; sold for scrapping 8 March 1948 to Ships Power & Equipment Corp., Barber, N.J. NARA-captioned photo 80-G-318644 shows the hull off the Okinawa beachhead circa April 1945 with the large 'H' marking - used to carry casualties to hospital ships. Complement 13 officers/104 enlisted; troop accommodations 16 officers/147 enlisted. COs: Heim (Oct 1944-May 1946), LTjg. D.N. McCafferty USNR (May-23 Sep 1946).

- Secondary compilation, the canonical per-hull photo archive; NARA photo metadata transcribed in captions (catalog is JS-rendered, not independently pulled). The Bikini evacuation claim is NavSource-only this session. Spec block is generic class text and conflicts with the BuShips roster on engine model (12-567A listed vs 12-278A assigned to the 932-979 block). No asbestos content.

[4]Consolidated era inference - BuShips SDB-1945 v2 machinery data for the LST-932-979 block (diesel plant, no boilers) + era amphibious-ship construction practice; LST-1-class profile search record [other_primary]

- Finding type
- asbestos_application
- Finding
- A diesel-powered LST built 1944 sits inside the era when asbestos was standard marine insulation material. With no steam plant, the boiler/turbine lagging pathway does not apply; era-standard asbestos-relevant applications aboard the type were diesel exhaust lagging and gaskets, engine-room thermal/acoustic insulation, deck coverings and tile, bulkhead and accommodation insulation, valve packing, and winch/crane brake linings.

- Finding type
- historical_record
- Finding
- Documents what LST(H) conversion entailed on a documented sister hull: LST(H)-464 was refitted with 60 hospital bunk beds in triple tiers, four surgical beds, an operating room, sterilizing room, dental office, laboratory, dressing room, and x-ray room, later adding a ward, sick-officer quarters, outpatient spaces, and a medical stock room. LSTs served as casualty treatment and evacuation platforms precisely because they retained armament and were never designated hospital ships.

Class/era context for the scale of interior rework, not a hull finding. No asbestos content in the source.

- Finding
- The builder yard site underwent documented Massachusetts Contingency Plan remediation during 2000s redevelopment: a chlorinated-solvent (PCE/CVOC) release to soil and groundwater was remediated under RTN 4-3023722 with a Class A-3 RAO and Activity and Use Limitations, and a contractor summary documents excavation and disposal of roughly 14,000 tons of PCB-contaminated soil and debris from shipbuilding-era dumping and on-site incineration.

- Builder-yard site record only, decades post-build - documents CVOC/PCB contamination at the former Bethlehem-Hingham site, NOT asbestos; no asbestos-specific release documentation was located in the DEP filings reviewed. Establishes the hull was built at a yard later documented as a contaminated site; says nothing about materials installed in this hull.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or litigation naming USS LST-950 / LST(H)-950 was found in the public sources searched. CourtListener authenticated searches returned zero hits across all designation variants - 'LST-950' (opinions and dockets), 'LST 950', 'LST(H)-950', and 'LSTH-950' (opinions). Secondary web sweeps surfaced no qualifying case and no law-firm marketing page naming this hull specifically.

Deck logs, builder work packages, and any scrapping-contract records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.

- Archival leads for this hull: NARA photo 80-G-318644 documents the hull off the Okinawa beachhead circa April 1945 in hospital-role markings (caption transcribed via NavSource); RG 24 WWII deck logs for LST-950 should exist but were not located in digitized form on archive.org; the NARA catalog (catalog.archives.gov) is JS-rendered and returned no API result without a key this session. Builder work packages and any LST(H) conversion specifications would be the strongest physical-material leads and are not digitized.

[9]Date cross-check: DANFS/NHHC + NavSource (decommissioned 23 September 1946; struck 10 June 1947) vs Wikipedia USS LST-950 infobox (decommissioned 18 July 1946; stricken 23 September 1946); shipbuildinghistory.com/navalmarinearchive build table ('Scrapped 1947') [other_primary]

- CORRECTION: the Wikipedia USS LST-950 infobox lists decommissioned 18 July 1946 and stricken 23 September 1946 - both contradicted by DANFS (decommissioned 23 September 1946, struck from the Navy list 10 June 1947) and NavSource (same), and internally contradicted by the article's own body text, which follows DANFS. Separately, secondary build tables print 'Scrapped 1947' where DANFS/NavSource document sale for scrapping 8 March 1948.
