- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry; for this numbered craft (no DANFS entry, excluded from NVR as a pre-1987 disposal) it is the most complete consolidated record located, and its commission date matches the batch's documented figure. Its '6051 series 71' engine text is a transcription of the GM 6-71-series engine fit documented in the sister-hull NRHP nomination (see ev-03). Contains no asbestos content.

- Finding type
- vessel_history
- Finding
- Yard-level documentation for this hull's builder: New Jersey Shipbuilding was an assembly line for LCIs on Arthur Kill at Barber (later absorbed into Perth Amboy, now Maurer); management was taken over by Todd Shipyards in 1942 at the Navy's request, and the yard closed after the war. Its build table lists LCI(L)-820 for the US Navy, delivered September 1944, disposition column 'Struck 1946' - the same entry given for adjacent hulls 815-819 and 821.

- Limitations
- Independent secondary compilation (Colton's shipbuilding-history table), not a registry document. 'Struck 1946' conflicts with NavSource's 'date unknown' and is applied uniformly to the whole Sep-44 block of hulls, so it reads as a block-level assumption rather than hull-specific data - treated as unverified and carried in gaps. Contains no asbestos content.

[4]NPS National Register of Historic Places nomination, USS LCI(L)-713, NRHP 07000300 (listed 12 April 2007) - sister-hull construction documentation for the LCI(L) type [nps]
- Locator
- NRHP 07000300 nomination, narrative description section (engine room, exhaust system, winch paragraphs)
- Finding type
- historical_record
- Finding
- The NRHP nomination for the surviving sister documents LCI(L) construction and machinery arrangement relevant to this hull's class: eight General Motors 6-71 diesel engines in two banks of four, each bank connected to a shaft with a four-foot propeller; a dual engine exhaust system with above-water and underwater exhaust, the latter used during landings to lessen engine noise; compartment-by-compartment arrangement including crew compartment, engine room, officer stateroom/radio room, troop spaces, and the gasoline-motored winch used to raise and lower the bow ramp. The nomination contains no asbestos or insulation-material claims.

- Sister-hull documentation (LCI(L)-713, built by George Lawley & Son, Neponset MA) describing the shared LCI(L) type - it does not name or document LCI(L)-820's own materials. Contains no asbestos information; used here only to confirm the all-diesel machinery arrangement and exhaust design underlying the era-inference row (ev-05).

- GAO product page HRD-80-2, Highlights block
- Finding type
- gov_survey
- Finding
- GAO reviewed the Navy's efforts to protect workers from asbestos exposure at the Long Beach and Norfolk Naval Shipyards, including the use of asbestos in Navy ships and the cost of removing it; the Navy's 1975 policy was to remove and replace asbestos insulation only when damaged or when removal was needed for repairs, modified in 1979 to selectively replace insulation in high-maintenance areas. Establishes Navy-wide asbestos insulation use spanning this hull's 1944 construction and commissioned-service era.

[6]Era inference built on: NavSource LCI(L)-351 class specifications for this hull (all-diesel GM 6-71-series plant); NRHP 07000300 sister-hull nomination (machinery and dual-exhaust arrangement, ev-03); GAO HRD-80-2 (Navy asbestos-use era, ev-04) [other_primary]

- Finding type
- asbestos_application
- Finding
- A diesel-powered landing craft built at a wartime emergency yard in August-September 1944 sits inside the Navy's documented asbestos-use era; era-standard small-craft applications aboard a vessel of this type and period were lagging on the dual (above-water/underwater) exhaust system, thermal insulation in the machinery spaces, gaskets and valve packing in piping systems, electrical insulation, and brake linings on the gasoline-motored bow-ramp winch. As an all-diesel craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply.

- The hull's WWII-era deck logs, if extant, are held in NARA Record Group 24 (Bureau of Naval Personnel logs), with Special List 44 the comprehensive item list through 1947. NARA's deck-log digitization program is Vietnam-era-focused; no digitized LCI(L)-820 deck log was located in the National Archives Catalog. Unexamined paper logs are the open lead for ship-specific service detail.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS LCI(L)-820 was found in the public sources searched (see search_ledger). CAVEAT: CourtListener could not be queried this session - the fleet-paced authenticated request budget was spent at each attempt (helper script enforced stand-down); logged as blocked in the search ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case; the only 'asbestos aboard' material is law-firm marketing content asserting asbestos aboard LCI-type craft without primary sourcing - excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - and the litigation repository search is a genuine open gap (throttled, not run). RG 24 deck logs, builder work packages, and Maritime Commission disposal records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
