- The ship's muster rolls for her entire U.S. Navy commissioned career - 13 April 1945 through 25 March 1947 - survive as a digitized NARA file unit (177 images, microfilm Roll No. 4036). Muster rolls are quarterly personnel rosters naming every officer and enlisted man attached to the hull at each reporting date, including changes of rating and personnel gains/losses - the primary-source population record for anyone who served aboard this vessel.

- Finding type
- historical_record
- Finding
- NHHC documents a deliberate coverage exclusion: DANFS parameters covered 'only commissioned Navy ships with assigned names,' and 'ships with only a designation, such as LSM, were not included in the DANFS series.' The Ship's History Office instead scanned an LSM/LSM(R) history compiled by Captain James B. Birindelli, SC, USNR (Ret.), distributed only as CD-ROM SH-0068 (non-word-searchable Adobe Acrobat) on request to the Naval Historical Center. Consequently no DANFS entry exists for LSM-483 - the standard NHHC ship-history source is confirmed absent for this hull by policy, not by omission.

- Finding
- Digitized war diaries for LSM Group Forty-Four - this hull's parent unit for her entire combat and occupation period - exist at NARA for March-December 1945. Group-level war diaries routinely carry task-organization enclosures listing assigned hulls, so these records are the likeliest contemporaneous operational source naming LSM-483's movements (Philippines/occupation service) during the period.

- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and program under which this 1945 LSM-1-class hull was mass-produced at a Gulf Coast commercial yard - and that wartime demand drove unprecedented asbestos utilization aboard hulls of this period.

[6]Era inference built on: NavSource LSM spec block (2 x GM 16-278A diesels, direct drive - no steam plant); LST-1-class profile finding that diesel amphibious construction concentrates exposure relevance in engine-room/exhaust lagging, gaskets, deck coverings, accommodation insulation; Corn & Starr 1987; GAO HRD-80-2 Navy-wide asbestos-use documentation [other_primary]

- Finding type
- asbestos_application
- Finding
- A 1945 diesel direct-drive landing ship sits inside the documented WWII-era asbestos-use window for U.S. shipbuilding; era-standard applications aboard a vessel of this type and period were engine-room thermal insulation and diesel-exhaust lagging, flange and machinery gaskets, valve packing, interior deck coverings, and accommodation-space insulation. As a diesel plant she carried no boilers - the steam-plant lagging pathway of larger combatants does not apply, but the amphibious-ship confined-space dynamic (berthing and engine spaces within a 203-ft steel hull) applies fully.

- Finding type
- gov_survey
- Finding
- GAO reviewed the Navy's asbestos-exposure protections at the Long Beach and Norfolk Naval Shipyards, including the use of asbestos in Navy ships, removal cost, and compensation programs; the Navy's 1975 policy was to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed for repairs, modified in 1979 to selectively replace asbestos insulation in high-maintenance areas. Program-level confirmation that asbestos insulation was standard aboard Navy ships through the era this hull was built and served (1945-1947 USN).

- Finding
- Site-level federal documentation of the facility where this hull was laid up 1947-1958: the former Lee Field NAS / Florida Group, Atlantic Reserve Fleet berths at Green Cove Springs (later Reynolds Industrial Park) were investigated under the FUDS program, which documented petroleum, solvent, and PCB (Askarel transformer-fluid) releases to the St. Johns River, asbestos abatement of site buildings, and period mothballing practices (dehumidification, paint chipping/repainting, overboard disposal of incomplete equipment per former-sailor interviews). Reportedly as many as 600 vessels were berthed at the piers during the reserve-fleet period.

- Limitations
- The site record is not a vessel record: it does not name LSM-483, and its asbestos findings concern site buildings (e.g., the power plant abatement scheduled 1987), not berthed hulls. Relevance is confined to describing mothballing-era maintenance practices at her documented layup berth. 'Normal military practice' dumping accounts rest on newspaper interviews with former sailors, not a surveyed work record. No hull-level asbestos finding.

- Absence of a located public record does not prove absence of asbestos aboard - a 1945-built amphibious hull is era-consistent with asbestos-containing insulation, gaskets, and deck coverings, and her 1970 cargo-ship rebuild in Dominican hands is a typical disturbance event at an undocumented yard. CourtListener coverage is limited to indexed opinions/dockets - MDL-875 dockets and un-indexed filings naming individual LSMs may exist outside it.
