LCI Group 7 in TU 1.2.5 comprised six landing craft: LCI-327, LCI-329, LCI-332, LCI-620, LCI(L)-549, LCI(L)-615.

She therefore survived both detonations afloat - consistent with her documented continuation at Kwajalein (TU 1.2.12) and 1949 sale.

- The Bikini Atoll council's target-vessel disposition list states: 'LCI-549: Used at Kwajalein as patrol vessel until June 1948. Granted final radiological clearance in August 1948 and towed to Port Chicago, California, in January 1949. Sold to the Learner Company in Alameda, California, on August 2, 1949, and delivered on August 19, 1949.' - corroborating that the hull survived the Bikini target array, remained in service at Kwajalein through June 1948 (consistent with the TU 1.2.12 Kwajalein Maintenance Force listing), passed a documented radiological clearance in August 1948, and returned to California for the 1949 Learner sale.

- Operation-level radiological context for this hull's 1946-48 service: after BAKER 'most of the target fleet [was] bathed in radioactive water spray and radioactive debris'; a target-vessel decontamination program began about 1 August 1946; on 10 August the decision was made to tow the surviving target fleet to Kwajalein 'where the work could be done in uncontaminated water,' the move accomplished during August-September; a major task at Kwajalein was offloading ammunition stored aboard; eight major ships and two submarines were towed back to the US/Hawaii for radiological inspection while twelve lightly-contaminated target ships were remanned and sailed home by their crews; all operations ran under radiological supervision with a 0.1 roentgen/day limit and ~18,875 film-badge dosimeters issued. This is the documented regime under which this hull's post-test handling occurred (TU 1.2.12 Kwajalein Maintenance Force).

- Finding
- A diesel-powered landing craft built January-February 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)-549 was found in the public sources searched (see search_ledger). The hull's documented material-disturbance events are the Bikini target-array exposure and post-test decontamination handling (1946-48) and her 1949 sale and scrapping at the Learner yard in Alameda CA - no asbestos documentation was located for either. Her Operation Crossroads service produced radiological-survey documentation (final clearance August 1948 per bikiniatoll.com) 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 2/8/1944-12/31/1945), NJSB build records, JTF-1 radiological survey files at NARA that would document the 1948 clearance, and any Maritime Commission sales-condition documentation for the 1949 Learner sale. Does not establish or defeat any claim of exposure or legal eligibility.
