- Finding
- NavSource's live USS LSM(R)-191 page, whose history extract is credited to LSM-LSMR Amphibious Forces, Vol. II, states that the hull was laid down 27 August 1944 at Charleston Navy Yard, launched 21 September 1944, and commissioned on 21 November 1944 with LTjg. John W. Loyer, USNR, in command. It records assignment to LSM Flotilla Nine, LSM Group Twenty-Seven, and LSM Division Fifty-Three; participation in the Okinawa Gunto operation from 26 March through 3 June 1945; decommissioning on 12 February 1946; striking on 26 February 1946; transfer for disposal; sale on 20 January 1948 to R.J. MacCallum of Compton, California; conversion to a barge; and final fate unknown.

- Limitations
- NavSource is a volunteer archive and the narrative is credited to a published compilation rather than a government-produced ship history. It documents service and disposition, not asbestos, insulation, hazmat condition, exposure, or causation. The cited .net page was live when checked; the dead navsource.org mirror was not used.

- Finding
- The National Archives at Atlanta finding aid for RG 181, Sixth Naval District at Charleston, lists a hull-specific folder titled 'LSM(R) 191 Structural and Test Firing Photographs' in Box 9, folder 7, with two packets of small photographs and 25 large photographs dated November-December 1944. The same finding aid separately lists proof and structural firing of LSM(R)s 188 and 189 and a preliminary rocket-firing report.

[5]Naval History and Heritage Command, Dictionary of American Naval Fighting Ships, USS Pringle (DD-477); corroborating NHHC article 'The Destruction of USS Pringle' [nhhc_danfs]

- Pringle DANFS narrative describing the 16 April 1945 rescue; NHHC Pringle destruction page rescue paragraph
- Finding type
- vessel_history
- Finding
- NHHC's DANFS entry for USS Pringle (DD-477) identifies LSM(R)-191 as part of the rescue group after Pringle was sunk off Okinawa on 16 April 1945. The entry states that LSM(R)-191, Hobson, and LCS(G)-34 rescued Pringle survivors; the related NHHC history page states that the three ships rescued 251 survivors. This is an operational-history reference to LSM(R)-191, not a material or asbestos record for the hull.

- Limitations
- The NHHC pages document the surrounding operation and LSM(R)-191's rescue role, not the ship's construction materials, asbestos content, crew exposure, or causation. The rescue total belongs to the Pringle survivor event and is not a crew figure for LSM(R)-191.

[6]HyperWar / ibiblio, Ships of the U.S. Navy 1940-1945, LSM(R)-188 class summary [other_primary]
- Locator
- LSM(R)-188 class specifications and propulsion summary
- Finding type
- asbestos_application
- Finding
- Class/era context: the LSM(R)-188 class was a diesel-powered Landing Ship Medium (Rocket) class built during the World War II shipbuilding period. HyperWar's class summary gives two GM diesels, twin screws, a 203-foot-6-inch length, 34-foot-6-inch beam, 13.2-knot speed, and a five-officer/76-enlisted complement. For a hull of this type and era, possible asbestos-relevant applications include diesel exhaust or machinery insulation, pipe insulation, gaskets, packing, electrical insulation, and fireproofing; these remain class/era inferences only.

- World War II LSM(R)-188-class construction and operating personnel
- Limitations
- This source describes the class, not LSM(R)-191's installed materials. It does not establish that asbestos was present aboard this hull, identify products or manufacturers, quantify material, describe condition, or establish exposure or causation. The class context is deliberately not promoted to a ship-specific finding.

[7]Batch research review of the sources listed in search_ledger rows sl-uss-lsm-r-191-lsmr191-01 through -08 [other_primary]
- Locator
- Source-review negative finding; see search_ledger and gaps
- Finding type
- historical_record
- Finding
- No ship-specific asbestos documentation was located in the official and archival sources reviewed for this hull: the live NavSource hull page, NHHC operational references, and the NARA RG 181 finding aid identify the vessel and its service or archival holdings but do not document asbestos, insulation composition, abatement, or a hazmat survey. The absence is reported as a research negative, not as proof that the hull never contained asbestos.

- Limitations
- A negative public-source finding is not proof of absence. NARA file contents, deck logs, war diaries, Navy yard work packages, and non-digitized surveys were not exhaustively retrieved. Asbestos documentation level therefore remains class_or_era, not ship_specific.

[8]CourtListener API v4 via /Users/charlesfletcher/devin-prompts/cl-auth-search.py; exact-name and hull-number attempts on 2026-09-30 [court_record]

- Finding type
- litigation_documented
- Finding
- CourtListener litigation sweep was attempted through the required authenticated helper for the exact name 'USS LSM(R)-191' and the hull-number query 'LSMR-191'. The helper authenticated both requests, but the fleet-wide pacing limiter then reported that the shared request budget was momentarily spent before results could be returned. No litigation classification is made from those blocked attempts.
