- DANFS documents for this hull: 'LST-628 was laid down on 10 April 1944 at Seneca, Ill., by the Chicago Bridge & Iron Co.; launched on 4 July 1944; sponsored by Mrs. P. G. Abernathy; and commissioned on 31 July 1944, Lt. Frank C. Siedenburg in command.' Assigned to the Asiatic-Pacific theater; participated in the assault and occupation of Okinawa Gunto in May 1945; performed occupation duty in the Far East until early March 1946. 'The ship was decommissioned on 3 April 1946 and struck from the Navy list on 3 July that same year. She was sold to the Ships & Power Equipment Corp., of Barber, N.J., on 9 December 1947 for scrapping.' Earned one battle star for World War II service.

Siedenburg, USNR, in command; international radio call sign NFGM. Campaign detail: assault and occupation of Okinawa Gunto 16-20 May 1945, assigned to LST Flotilla Six (CAPT. Laidlaw), LST Group Seventeen (CAPT. E. Watts USN), LST Division Thirty-four. Navy Occupation service, Far East: 6-23 September 1945, 3 October-7 December 1945, and 29 January-4 March 1946.

Awards display: American Campaign Medal, Asiatic-Pacific Campaign Medal (1), WWII Victory Medal, Navy Occupation Service Medal (Asia clasp), Philippine Liberation Medal. Photographic record: NHHC photo NH 82166 shows LST-628 entering San Francisco Bay flying a homeward-bound pennant, early 1946 (via Vallejo Naval and Historical Museum); a contributed photo shows her beached at Lingayen Gulf 9 January 1945 unloading US Army troops, and another shows her with causeway attached, beached at Manus, Admiralty Islands.

- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - its milestone dates match DANFS exactly for this hull and its spec block tracks BuShips Ships' Data 1945 (see ev-03). Contains no asbestos content. The NH 82166 NHHC image is carried by caption reference; the NHHC online photo page 404s. The Lingayen Gulf 9 Jan 1945 photo caption documents presence there, but neither DANFS nor NavSource's own campaign table credits a Lingayen engagement (see gaps). No hazmat or material record for the 1947 breakup was located - predates modern ACM-handling regulation.

- Finding
- The official BuShips design table places LST-628 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-628 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 April-July 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.'

- Chicago Bridge & Iron yard table, LST-628 row; yard description paragraph
- Finding type
- historical_record
- Finding
- Independent build-table corroboration: the Seneca yard table lists LST-628 laid 4/10/1944, launched 7/4/1944, delivered 7/31/1944 (85 days on ways, 27 days fitting out, 112 days total) - matching DANFS/NavSource to the day. Disposition column reads 'scrapped 1947' - consistent with the DANFS 9 December 1947 sale for scrapping. 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.

CourtListener was searched this session (authenticated API v4): quoted 'LST-628', 'USS LST-628', and 'LST 628' across opinion search all returned 0; quoted 'LST-628' and 'LST 628' on docket search returned 0; an unquoted 'LST-628' opinion sweep returned 92 token-level collisions with no qualifying hit (see search_ledger sl-04/sl-05). Secondary web sweeps surfaced no qualifying case and no Wikipedia article exists for this hull; the only 'asbestos' material for landing ships is generic law-firm marketing - excluded by source policy.

- Finding
- 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, and possibly clarification of her January 1945 presence at Lingayen Gulf (photo-documented but not campaign-credited). The NHHC photographic file (NH 82166) independently documents the ship's return to San Francisco in early 1946.
