- Finding
- NavSource lists the following vessel specifications: 5 officers and 54 enlisted; a 203-foot-6-inch overall length; a 34-foot-6-inch beam; diesel fuel capacity of 1,225 barrels; and two Fairbanks Morse model 38D81/8X10 reversible diesel engines, direct drive, 1,440 bhp each at 720 rpm, on twin propellers for 2,800 shp.

- Ship's company (reported complement)
- Limitations
- The listed specifications are carried as reported by this specialist archive and the complement has not been verified against DANFS/NHHC. The diesel-plant description does not identify insulation, gaskets, packing, or any material as asbestos and cannot establish asbestos aboard this hull.

[3]Batch-6066 research ledger for USS LSM-263: live NavSource hull page review; authenticated CourtListener helper attempt; Firecrawl quota response [other_primary]
- Locator
- search_ledger rows sl-uss-lsm-263-lsm263-01 through sl-uss-lsm-263-lsm263-04
- Finding type
- historical_record
- Finding
- No ship-specific asbestos documentation was located in the completed, publicly accessible portions of this sweep: the live NavSource hull page has no asbestos, abatement, hazmat, survey, or insulation-material finding. CourtListener exact-name and hull-number searches were initiated through the required authenticated helper but did not return before the helper's 30-second network timeout; they are not classified as no-result. Firecrawl search/scrape was unavailable because its shared keyless quota was exhausted.

- Limitations
- This is a constrained-search result, not proof that asbestos was absent and not a CourtListener no-result. It establishes neither asbestos presence nor absence, individual exposure, causation, legal eligibility, or litigation disposition. CourtListener and Firecrawl gaps remain open.

- Limitations
- Record-group-level guidance only; no box, file, plan, material list, or hull-specific document was retrieved. It does not establish that any asbestos-related document for LSM-263 exists or that asbestos was present aboard her.

- Finding
- NavSource's USS LSM-263 hull page identifies an LSM-1-class Landing Ship Medium laid down 1944-05-16 at Federal Shipbuilding and Dry Dock Co., Newark, New Jersey; launched 1944-06-17; and commissioned 1944-07-03. It reports assignment to LSM Flotilla One, LSM Group Two, and LSM Division Four; participation in the Okinawa Gunto assault and occupation from 1945-05-30 to 1945-06-30; Far East occupation service from 1945-09-23 to 1945-11-28; decommissioning at NOB Guam on 1946-12-29; one World War II battle star; and sale to Standard Dredging Co. on 1947-03-20, with subsequent fate unknown.

- Limitations
- This is a live specialist archive page, not a DANFS/NHHC hull history; its history extract attributes itself to LSM-LSMR Amphibious Forces, Vol. II (1997). It supports the stated identity and timeline only. It contains no asbestos, insulation-material, survey, abatement, exposure, causation, or litigation finding.
