[2]DANFS, LST-581 (official NHHC entry; archived Wayback capture dated 2025-02-02; live NHHC URL returned 404 on 2026-10-02) [nhhc_danfs]

- DANFS LST-581 entry, single narrative paragraph
- Finding type
- vessel_history
- Finding
- DANFS documents that LST-581 was laid down 17 May 1944 at Evansville, Indiana, by Missouri Valley Bridge & Iron Co.; launched 29 June 1944; sponsored by Mrs. Jack Rogers; and commissioned 27 July 1944 with Lt. O. F. Rapelyea in command. It assigns the ship to the Asiatic-Pacific theater and the assault and occupation of Okinawa Gunto in May-June 1945; records Far East occupation duty through late January 1946, decommissioning 28 January 1946, transfer to Military Sea Transportation Service on 31 March 1952, striking on 1 June 1972, and sale for scrapping on 25 May 1973 to Dongkuk Steel Co. of America, Inc., Los Angeles. DANFS credits one World War II battle star.

- Ship-specific history, not a materials or exposure record. The presently live NHHC canonical URL returned 404, so this row cites a verified Wayback capture and labels it archived. DANFS does not state the SCAJAP designation, machinery details, asbestos presence, product identity, quantity, worker exposure, or legal eligibility.

[3]NavSource Online: Amphibious Photo Archive, USNS T-LST-581 / ex USS LST-581, 10/16/160581 (verified live 2026-10-02) [other_primary]

- Finding type
- vessel_history
- Finding
- NavSource's hull timeline identifies LST-581 as an LST-542-class tank landing ship, gives the 17 May 1944 Evansville keel date, 29 June launch, and 27 July 1944 commissioning, and lists Lt. O. F. Rapelyea as commanding officer through 28 January 1946. Its campaign table dates the Okinawa Gunto assault-and-occupation participation 16 May-30 June 1945 and its occupation-service table lists 6-23 September 1945 and 23 December 1945-28 January 1946. It says the ship was assigned to COMNAVFE Shipping Control Authority for Japan as Q030 after decommissioning, transferred to MSTS on 31 March 1952 as USNS T-LST-581, and placed out of service and struck on 1 June 1972. Its class specifications list two General Motors 12-567A 900-hp diesel engines, a Falk reduction gear, two propellers, 1,700 shp total, three 100-kW 230-V DC diesel-drive generators, and a 13-officer/104-enlisted complement.

- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry or hull survey. Its machinery and complement block is class-standard and does not prove individual components or materials aboard this hull. Its timeline also states a 25 May 1948 MARAD transfer while separately placing the ship in MSTS from 1952; that internally problematic 1948 statement is not adopted. This source contains no asbestos documentation.

- Finding type
- historical_record
- Finding
- NARA's Special List 44 identifies LST-581 and a logbook coverage interval of 27 July 1944 through 30 June 1945. This is a ship-specific archival lead for contemporaneous operational records covering commissioning and the Okinawa campaign window.

- Finding
- GAO's Navy-wide asbestos program report documents extensive asbestos insulation aboard Navy ships and substitution of alternative insulation materials beginning in the early 1970s. That program-level chronology encompasses LST-581's 1944 construction and naval/MSTS service period.

- Finding type
- asbestos_application
- Finding
- Class/era context: LST-581 was a diesel-powered LST-542-class landing ship built during the Navy's asbestos-use era. The period LST design had diesel, rather than boiler-and-turbine, propulsion; therefore boiler and main-steam lagging must not be inferred for this hull. Any asbestos-relevant applications potentially associated with this era/type remain unconfirmed for LST-581 without a hull-specific material record.

[7]Completed authoritative-source sweep: NHHC/DANFS, NARA Special List 44, NVR access check, GAO product-page check, and NavSource historical compilation; CourtListener authenticated exact-name and exact-hull queries were paced pending by the fleet limiter at research close [other_primary]

- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement contract, hazmat disclosure, material list, or product-identification record was located for USS LST-581 in the completed source sweep. No asbestos finding is made for the hull. The CourtListener litigation sweep remains incomplete because the required authenticated helper reported fleet-wide pacing exhaustion before returning results; it is a gap, not a negative litigation result.

- Limitations
- An absence of located public documentation does not establish absence of asbestos aboard. The completed sources have incomplete archival and litigation coverage. CourtListener opinions and RECAP dockets for both the exact ship name and exact hull number must be completed before any litigation negative can be claimed.
