- vessel_history
- Finding
- LSM-120 was laid down 28 October 1944 at Brown Ship Building Co., Houston, Texas; launched 18 November 1944; and commissioned as USS LSM-120 on 10 December 1944. The hull history records Asiatic-Pacific service, one battle star for World War II service, Okinawa Gunto operations from 30 May to 30 June 1945, Far East occupation service from 20 September to 10 October and 22 October to 3 December 1945, decommissioning on 14 May 1946, and sale in October 1958 to American Tug Boat Co. for conversion to a barge.

- Brown Ship Building construction workforce; ship's company; embarked personnel
- Limitations
- Establishes the reported chronology, service, award count, decommissioning, and disposition. NavSource is a specialist historical compilation rather than a Navy material survey; it does not identify asbestos, insulation composition, hazmat condition, individual exposure, or causation.

- Finding
- The Naval History and Heritage Command's United States Pacific Fleet Organization dated 1 May 1945 lists LSM 120 in LSM Flotilla Twelve, LSM Group Thirty-Five, LSM Division Seventy, commanded by Lt. R. M. Korn, USNR.

- Ship's company, 1 May 1945
- Limitations
- Establishes the 1 May 1945 organization and commanding officer only. It conflicts with the NavSource page's Flotilla Twelve/Group Thirty-Four/Division Sixty-Seven assignment; the official dated organization is used for this date and the discrepancy is carried as a gap. It contains no asbestos or material information.

- Finding
- The hull-page specification block gives a complement of 5 officers and 54 enlisted, troop accommodations for 2 officers and 46 enlisted, and two Fairbanks-Morse 38D81/8X10 reversible direct-drive diesel engines rated 1,440 BHP each, with twin propellers and 2,800 shp.

- Finding type
- asbestos_application
- Finding
- A peer-reviewed historical study documents extensive asbestos use as fireproofing and insulation in U.S. shipbuilding during the 1940s. For LSM-120, this is class/era context only: the study does not name the hull or identify a product installed aboard it.

- Limitations
- Program- and era-level evidence, not ship-specific documentation. It does not establish product identity, quantity, location, condition, present-day presence, individual exposure, causation, or legal eligibility for LSM-120.

- search_ledger rows sl-uss-lsm-120-lsm120-01 through -05
- Finding type
- historical_record
- Finding
- No ship-specific asbestos documentation was located in the reviewed public source set: the reviewed hull page and NHHC organization record document identity, service, propulsion, complement, and disposition but do not document asbestos, insulation composition, abatement, a hazmat survey, or a material inventory.

- Limitations
- A negative public-source finding does not prove asbestos was absent. Firecrawl was unavailable because its keyless quota was exhausted, and NARA's relevant hull drawings/specifications were not retrieved. This finding does not establish or defeat exposure, causation, or legal eligibility.

[7]CourtListener API v4 via /Users/charlesfletcher/devin-prompts/cl-auth-search.py; fleet-wide pacing stand-down before HTTP request [court_record]

- Finding type
- historical_record
- Finding
- The required authenticated CourtListener v4 searches for the exact name 'USS LSM-120' (opinions and dockets) were attempted through cl-auth-search.py, but the fleet-wide pacing limiter halted each request before an HTTP request was made. The exact hull-number searches remain unrun after that stand-down. No litigation result is asserted.

- Finding
- National Archives guidance identifies Bureau of Ships Record Group 19 ship engineering drawings and microfilm drawings as potential sources for insulation and lagging information, including S39 (Insulation and Lagging) and S48 (Piping) codes. No LSM-120 drawing or specification was retrieved.

- Limitations
- This is a record-path lead, not proof that an LSM-120 record exists or that it would document asbestos. No box-, drawing-, or specification-level inspection was performed, and nothing here establishes materials aboard the hull.
