- Establishes decommissioning, strike, and reported sale; the buyer spelling differs across sources ('Guntert & Zimmerman' here, 'Gunter & Zimmerman' in the ShipbuildingHistory yard table) and post-sale fate is undocumented. No shipbreaking, hazmat, or asbestos record is supplied.

- Finding type
- vessel_history
- Finding
- The official NHHC United States Pacific Fleet Organization record for 1 May 1945 lists LSM-90, marked '(GF)' (group flagship), in LSM Division 50 under LSM Group 25 (ComLSMGrp 25 Lt. Cdr. T. A. Peacock, USNR) and LSM Flotilla Nine (Comdr. D. L. Francis), with Lt. L. M. Decker (USNR) as commanding officer.

- Limitations
- Official dated snapshot corroborating assignment and command on 1 May 1945. It places LSM-90 in Division 50 - not Division 49 as the NavSource/Turner extract states - and shows Peacock, not Brouwer, commanding Group 25 (NHHC places Brouwer over Group 26); the divergence is carried in gaps. It provides no full service history and no asbestos, insulation, exposure, or causation finding.

- Finding type

- Finding
- Independent corroboration of construction and disposition: the ShipbuildingHistory Brown Shipbuilding yard table lists LSM-90 as Brown hull number 195 with keel laid 30-Aug-44, launched 23-Sep-44, delivered 20-Oct-44, and 'Sold to Gunter & Zimmerman 1948'; the uboat.net Allied Warships entry gives a contract (ordered) date of 15 September 1943 and the same build, commissioning, decommissioning (1 May 1946), strike (5 June 1946), and sale (16 January 1948) dates.

[5]Inference from the ship-specific NavSource diesel specification and the documented source-review negative [other_primary]
- Locator
- NavSource propulsion/specification block; source-review negative documented in search ledger
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, or condition report was located. Because LSM-90 was a World War II U.S. Navy diesel landing ship, machinery or diesel-exhaust insulation, gaskets, packing, electrical insulation, and deck covering are possible class/era application categories, but none is documented aboard this hull.

- search_ledger sl-uss-lsm-90-lsm90-07 and -08; authenticated exact-name opinion and hull-number docket queries
- Finding type
- historical_record
- Finding
- The authenticated CourtListener sweep found no qualifying asbestos litigation record for USS LSM-90. The exact-name opinion search returned three matters, each reviewed and classified as a name/text collision or other litigation: Amerace Esna Corp. v. United States (U.S. Court of Claims, 1972 - a patent-compensation action whose text references 'Medium Landing Ship (LSM) 419' and BuShips Instruction 9190.12, not LSM-90); Tyrone Berry v. State (Tex. App. 14th Dist. 2015 - a criminal appeal); and Penn Virginia Oil & Gas v. De La Garza (Tex. App. 1st Dist. 2015 - an oil-and-gas dispute whose 'LSM' tokens are OCR artifacts such as 'lsmlly' for 'usually'). The hull-number docket search returned broad tokenized matches with no qualifying case.

- Limitations
- This is a search result, not proof that no unindexed or non-text-linked case exists. The Berry opinion's matched token could not be confirmed - its full-text fetch was fleet-pacing limited on repeated attempts; its classification rests on case metadata (Texas criminal appeal with no asbestos or maritime indicia). None of the returned matters identifies this vessel, its crew, or asbestos exposure aboard this hull.

- Finding type

- Finding
- No ship-specific asbestos documentation was located in the public sources reviewed: the live NavSource hull page, official NHHC organization record, uboat.net, ShipbuildingHistory yard table, and authenticated CourtListener results contain no asbestos survey, insulation-material statement, abatement record, hazmat disclosure, or qualifying asbestos litigation record for LSM-90.

- A negative public-source finding is not proof that asbestos was absent. Non-digitized Navy, shipyard, reserve-fleet, and post-sale records may contain additional evidence; asbestos documentation therefore remains class_or_era.

- Finding
- During World War II, USS LSM-90 was assigned to the Asiatic-Pacific Theater with LSM Flotilla Nine, LSM Group Twenty-Five, and LSM Division Forty-Nine, and participated in the Okinawa Gunto operation (assault and occupation of Okinawa Gunto) from 18 April to 30 June 1945. NavSource photo captions also place the ship beached at Laoag, Luzon, P.I., 25 to 28 July 1945 alongside LSM-144, LSM-180, and LSM-186. The ship earned one battle star for World War II service and later served two Far East occupation periods (11 to 20 September 1945 and 15 November to 30 December 1945).

Not a complete voyage narrative; no asbestos, insulation, exposure, or causation content.
