- NavSource is a volunteer secondary compilation, not a primary registry; the history extract is credited to Turner Publishing's LSM-LSMR Amphibious Forces Vol. II, a commercial unit history compiled from official records. Milestones here are corroborated by shipbuildinghistory.com and uboat.net. The spec block is class-level (LSM-1 class), not a hull-specific spec sheet. No asbestos or material content. Stricken given only as 'in 1947' - a precise 31 October 1947 date comes from uboat.net (secondary).

- Finding
- Brown Shipbuilding yard table entry for this hull (yard hull no. 271): keel laid 13-Jan-45, launched 3-Feb-45, delivered 9-Mar-45 - matching the NavSource timeline - with disposition 'Sold to Foss 1947, converted to barge Foss 160, later Chikoot, ON 264434, scrapped.' Yard context: Brown Shipbuilding was built in 1941 by George and Herman Brown at the junction of Greens Bayou and the Houston Ship Channel with $9mm from the Navy; the yard built 12 PCs, 32 LCI(L)s, 61 destroyer escorts, and 254 LSMs - 359 vessels in four years. In 1949 the yard was leased to Todd Shipyards Corp. as its Houston Division until 1984.

- Official Navy description of the type this hull belongs to: 'Needing a landing ship somewhere between the size and displacement of an LCI (Landing Craft, Infantry) and an LST (Landing Ship, Tank), the Navy turned the problem over to its architects and designers who came up with the compact and maneuverable LSM (Landing Ship, Medium).' 558 LSMs were built for the USN between 1944 and 1945 (class literature; secondary).

[5]Era inference built on: NavSource LSM-1 class specification block (Fairbanks-Morse diesel direct-drive plant); shipbuildinghistory.com Brown yard record (254 LSMs built at Greens Bayou 1944-45); GAO HRD-80-2 era documentation (see ev-06) [other_primary]

- Finding type
- asbestos_application
- Finding
- A diesel-powered landing ship built January-March 1945 sits squarely inside the Navy's documented asbestos-use era. Era-standard applications aboard a vessel of this type and period were diesel exhaust-uptake lagging, machinery and piping insulation, gaskets, valve packing, electrical insulation, accommodation joiner/lining, and winch brake linings (the class carried bow doors and ramp machinery). As a diesel direct-drive vessel she carried no steam plant - the boiler/turbine lagging pathway of steam ships does not apply.

- Finding
- The VA recognizes military asbestos exposure as a basis for disability compensation and lists shipyards among the work areas, and pipes, insulation, and clutch facings/brake linings (friction products) among the products, associated with service-era exposure - the same categories that apply to this hull's construction yard and era-standard shipboard materials.

- Physical-presence documentation for this hull: a US Naval Historical Center photograph (NH 83277) shows her underway in San Francisco Bay 1945-46, and a crew-taken photograph places her at Shanghai, China, in 1946 moored forward of YO-77 - consistent with her China Service Medal window. Deck logs for her 1945-47 service exist in NARA RG 24 but are not among the logs digitized on the National Archives deck-log list (sisters LSM-448, LSM-455, LSM-462, and LSM-540 are digitized; LSM-464 is not).

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or litigation naming USS LSM-464 was found in the public sources searched (see search_ledger). CourtListener searches returned no qualifying result - 'LSM-464' opinions produced 12 hits that are all name collisions (USPS employment litigation, an unrelated 'LSM 128' commercial case), 'LSM-464' dockets produced 619 tokenized hits with no vessel-relevant match in the returned page, '"USS LSM-464"' and '"LSM-464" asbestos' opinion queries both returned zero. The only 'asbestos aboard' material found is law-firm marketing content naming the Brown Shipbuilding yard generally (mesothelioma.com, mesotheliomalawyercenter.org, mesothelioma.net) - excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - the hull was built in the peak era of Navy asbestos use and spent 33+ years as a working barge after Navy disposal. Does not establish that asbestos is or was present, does not establish or defeat any claim of exposure or legal eligibility.
