- DANFS documents for this hull: 'LST-622 was laid down on 15 March 1944 at Seneca, Ill., by the Chicago Bridge & Iron Co.; launched on 8 June 1944; sponsored by Mrs. Ray Menefee; and commissioned on 26 June 1944.' Assigned to the Asiatic-Pacific theater; participated in the Lingayen Gulf landing in January 1945 and the assault and occupation of Okinawa Gunto from March to June 1945. 'Following the war, LST-622 was decommissioned on 14 March 1946 and struck from the Navy list on 12 April that same year. On 13 April 1948, the ship was sold to Kaiser Co., Inc., Seattle, Wash., for scrapping.' Earned two battle stars for World War II service.

No hazmat or material record for the 1948 breakup was located - predates modern ACM-handling regulation.

- The official BuShips design table places LST-622 in the LST-542-931 design group: 328 ft oa, 50 ft beam, ~2,366 t light / 3,960-4,080 t trial displacement, 11.6 kt, 2 x General Motors 12-567A diesels ~1,700 shp, 2 shafts via Falk reduction gears; accommodations 13 officers/106 enlisted. Engine-variant blocks LST-932-979 and LST-1060-1080 carried GM 12-278A engines - LST-622 is not in those blocks. Diesel machinery plant throughout: no boilers on the type.

- Finding type
- asbestos_application
- Finding
- Era/design inference for a diesel-powered LST built March-June 1944: with no boilers, asbestos-relevant applications concentrate in GM diesel exhaust lagging and gaskets, engine-room thermal/acoustic insulation, deck coverings/tile, bulkhead and accommodation insulation, valve and flange gaskets, machinery packing, and winch/crane brake linings. WWII-era naval construction used asbestos-bearing insulation as standard material across these applications (GAO program context).

- Finding
- Contemporaneous account of the inland LST construction and ferry program: Chicago Bridge & Iron Co., Seneca, Ill., was one of five inland builders whose ships traveled ~1,342 river miles to New Orleans in reduced commission under Navy ferry crews working the Illinois and Mississippi rivers - the delivery pathway by which inland-built LSTs like this hull reached the fleet. 'The construction of LST's, moreover, was of primary importance.'

- Finding
- Independent build-table corroboration: the Seneca yard table lists LST-622 laid 3/15/1944, launched 6/8/1944, delivered 6/26/1944 (85 days on ways, 18 days fitting out, 103 days total) - matching DANFS/NavSource to the day. Yard description: the Navy requisitioned the Chicago Bridge facility at Seneca in 1942 and invested ~$6M in its improvement; a 200-acre site east of town; postwar sold to Union Mechling in 1949. Disposition column reads 'scrapped 1947' - conflicting with the DANFS 1948 sale date (see gaps).

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS LST-622 was found in the public sources searched. CAVEAT: CourtListener could not be queried this session - the helper returned fleet-wide pacing (shared ~114/hr budget momentarily spent) on all attempts; logged as blocked in search_ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case; the only 'asbestos' material for landing ships is generic law-firm marketing (e.g., gorilaw.com's landing-ships page, which does not name this hull) - excluded by source policy.

[10]Date-conflict documentation: Wikipedia USS LST-622 article body ('decommissioned on 11 January 1946') vs DANFS and NavSource (14 March 1946) - the Wikipedia infobox itself prints 14 March 1946 [other_primary]

- Finding type
- historical_record
- Finding
- CORRECTION: secondary copies of this ship's entry circulate a decommissioning date of 11 January 1946 (Wikipedia body text, repeated by downstream mirrors). The Wikipedia article is internally inconsistent - its own infobox carries 14 March 1946. DANFS states 'LST-622 was decommissioned on 14 March 1946,' NavSource prints 'Decommissioned, 14 March 1946,' and her last commanding officer's tenure ended 14 March 1946 (NavSource CO table). The 14 March 1946 date is carried in this record; the 11 January variant is not supported by any located primary source.

- Archival leads for this hull: NARA RG 24 deck logs and RG 38 war diaries for 1944-46 would carry her detailed movements, availabilities, and any recorded yard work - the most likely official source for any maintenance-period material detail. The NHHC photographic file (NH 79016) independently documents the ship's presence at San Francisco in 1946 during her final months.
