- NavSource is a volunteer secondary compilation - dates generally track official records but the page is not a primary registry. Key claims corroborated independently here: builder/completion/disposition by the shipbuilding-history build table (ev-02); Crossroads target-vessel status by the official NHHC JTF-1 composition document (ev-03) and the BuShips administrative-history target-ship list (ev-08); survival of both shots by the NHHC sunk lists (ev-04); the 10 Aug 1946 scuttling off the Bikini Lagoon entrance by the NHHC disposition list (ev-05), NPS SCRC-37 (ev-07), and bikiniatoll.com (ev-06). The Allen M. Sumner gunfire detail (167 rounds) rests on the NavSource/Turner sourcing only - DANFS places DD-692 on Crossroads support duty in that window but does not name this hull; the DD-692 August 1946 deck log is not digitized. The page prints the decommissioning date as unknown. Contains no asbestos or material content.

- The official JTF-1 composition lists LCI-620 once: under Task Unit 1.2.5 (Landing Craft Unit), LCI Group 7 [LCI GRU 7], listed WITHOUT asterisk - i.e., a TARGET vessel in the Bikini target array for the atomic tests (the TG 1.2 preamble legend: 'Nontarget ships (*) supported preparation, placement, and salvage of the targets'). LCI Group 7 comprised six landing craft: LCI-327, LCI-329, LCI-332, LCI-620, LCI(L)-549, LCI(L)-615. Unlike sisters 329, 549, and 615, LCI-620 does NOT appear on the TU 1.2.12 (Kwajalein Maintenance Force) nontarget list - consistent with her being scuttled at Bikini on 10 August 1946 before the fleet's move to Kwajalein was accomplished.

She therefore survived both detonations - bikiniatoll.com records she was 'deliberately beached before Baker shot' (ev-06), which the NHHC fact sheet generalizes: the landing craft beached on Bikini Island were among the exceptions to the post-Baker contamination regime.

LCI-620 was the only one of the six sunk at Bikini itself - on the same date (10 August 1946) the decision was made to tow the surviving target fleet to Kwajalein (ev-09).

- The Bikini Atoll council's target-vessel disposition list states: 'LCI-620: Deliberately beached before Baker shot.

This is consistent with the NHHC fact sheet's note that 'the landing craft beached on Bikini Island' were among the exceptions to the post-Baker contamination regime (ev-09).

- A diesel-powered landing craft built April-May 1944 sits squarely inside the Navy's documented asbestos-use era. Era-standard applications aboard a small diesel craft of this type were diesel exhaust and muffler lagging, gaskets and valve packing in engine and piping systems, electrical insulation on wiring and in control panels, and thermal insulation in the confined machinery spaces. As a diesel vessel she carried no steam plant - the boiler/turbine lagging pathway of steam ships does not apply.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS LCI(L)-620 was found in the public sources searched (see search_ledger), and CourtListener returned zero opinions and zero dockets under all tested name forms. The hull's documented material-disturbance events are the Pearl Harbor Naval Shipyard target-preparation availability for Crossroads landing craft (class level, ev-08), the Bikini target-array exposure, deliberate beaching, and scuttling (1946) - no asbestos documentation was located for any of them. The Crossroads phase produced radiological-control documentation at program level (ev-09) but no asbestos-related record surfaced in the sources searched.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard. Open leads: undigitized deck logs (SL44 window 5/31/1944-6/30/1945), NJSB build records, JTF-1 target-preparation and radiological survey files at NARA, and the DD-692 August 1946 deck log (not digitized) for the scuttling detail. Does not establish or defeat any claim of exposure or legal eligibility.
