- Limitations
- NavSource compiles the Turner Publishing 'LSM-LSMR Amphibious Forces Vol. II' (1997) extract - a compiled secondary history, not a contemporaneous primary Navy record; it contains no asbestos information. No campaign participation is listed for this hull - consistent with its late commissioning (January 1945) but the page gives no itinerary detail between commissioning and occupation service.

- Finding
- The Brown Shipbuilding yard table lists hull no. 243 as 'LSM 366, Landing Ship': keel laid 25-Nov-44, launched 16-Dec-44, delivered 17-Jan-45, disposition 'Laid up 1947, sold to James K. Ulrick 1958, resold 1961 as Caicos Cloud' - corroborating the NavSource dates exactly and adding the builder's yard hull number. The yard (built 1941 by George and Herman Brown at the junction of Greens Bayou and the Houston Ship Channel with $9M from the Navy) built 12 PCs, 32 LCI(L)s, 61 DEs, and 254 LSMs - 359 vessels in four years.

- Yard-level history of the builder: Brown Shipbuilding was established in 1941 by George and Herman Brown of the Brown & Root construction company at Greens Bayou off the Houston Ship Channel; it used assembly-line construction and launched vessels sideways into the narrow waterway; the yard employed more than 25,000 workers at peak starting in late 1942 and built destroyer escorts, submarine chasers, landing craft, and 254 LSMs - the builder environment in which this hull (yard no. 243) was constructed.

[5]Consolidated era inference - NavSource LSM-366 specification block (Fairbanks-Morse diesel plant, no boilers) plus documented WWII amphibious-ship construction practice (see class-or-era framing in this record) [other_primary]
- Locator
- Built on NavSource specifications block for this hull (propulsion section)
- Finding type
- asbestos_application
- Finding
- Era/design inference for a diesel-powered LSM-1-class hull: with no boilers or steam plant aboard, asbestos-relevant applications are diesel exhaust lagging and gaskets, engine-room thermal/acoustic insulation, deck coverings and tile, bulkhead and accommodation insulation, valve packing, and winch/crane brake linings. WWII-era federal policy reserved asbestos supply for shipbuilding, and amphibious construction of 1944-45 was built to wartime emergency specifications in which asbestos insulation products were standard.

- Study period

- Population
- Brown Shipbuilding construction trades (1944-45); ship's company (5 officers/54 enlisted)
- Limitations
- Class/era inference only - no ship-level asbestos record exists for this hull. The inference is weaker than for steam-powered ships: the absence of boilers removes the highest-density asbestos application typical of naval construction. Establishes no quantities, no fiber content, and no exposure for any individual.

- Archival leads located: NARA holds the war diary of Commander LSM Group Thirty-Eight for November 1945 - the group to which LSM-366 was assigned during its Far East occupation-service window (9 October-16 November 1945) - and a muster-roll file unit for Commander Florida Group Atlantic Reserve Fleet (December 1945-January 1949) covering the Green Cove Springs lay-up period in which this hull was held. Sister-hull LSM muster rolls exist in the same RG 24 series, indicating a per-hull LSM-366 roll likely exists, though the catalog's fuzzy search did not surface its NAID in the first 69 fuzzy hits.

- Finding type
- vessel_history
- Finding
- NHHC describes the type's design origin: needing a landing ship 'somewhere between the size and displacement of an LCI (Landing Craft, Infantry) and an LST (Landing Ship, Tank),' the Navy produced 'the compact and maneuverable LSM (Landing Ship, Medium).' The NavSource LSM/LSM(R) type index states 558 LSM and LSM(R) hulls were built during WWII, most serving in the Asiatic-Pacific Theater.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum record, or docketed litigation naming LSM-366 or Caicos Cloud was found in the public sources searched (see search_ledger). CourtListener returned zero results for 'LSM-366' (opinions and dockets), 'LSM 366' and 'USS LSM-366' (opinions), and 'Caicos Cloud' (opinions and dockets) - no qualifying asbestos litigation, no other litigation, no name collisions. The only 'asbestos aboard' content located is law-firm/marketing material (e.g., mesothelioma.com Brown Shipbuilding jobsite page) asserting asbestos without primary sourcing - excluded by source policy.

- Absence of a located public record does not prove absence of asbestos aboard - a 1944-45 hull built under wartime specifications is era-consistent with retained asbestos applications. Does not establish that asbestos is or is not present; does not establish or defeat any claim of exposure or legal eligibility.
