- USS LST-30 (LST-1 class) laid down 12 January 1943 at Dravo Corp., Neville Island, PA; launched 3 May 1943; commissioned 3 July 1943, LT William W. Ennis, USNR, in command. International radio call sign NFLO. Assigned to the Europe-Africa-Middle East Theater; campaign listed: Invasion of Normandy (6-25 June 1944). One battle star. Decommissioned 6 March 1946; struck from the Naval Register 8 May 1946; sold for conversion to merchant service 2 April 1947 to W. Horace Williams Co., New Orleans, LA. Commanding officers (all Navy, USNR/USN): LT Ennis (3 Jul 1943-1944), LT Figaro (1944-1945), LT Boldt (1945-1946), LTjg Swain (1946-6 Mar 1946). Specifications: 1,625 t light / 4,080 t full load / 2,366 t beaching; 328 ft oa; 50 ft beam; 11.6 kt; complement 13 officers/104 enlisted; troops 16 officers/147 enlisted; propulsion two GM 12-567A 900 hp diesels, single Falk main reduction gear, three diesel-drive 100 kW 230 V DC generators, two propellers, twin rudders; 2 LCVP. Period photographs document the ship beached at Normandy after 6 June 1944 alongside USS LST-60, and underway in San Francisco Bay circa 1946 (NHHC photo NH 82164, via Vallejo Naval and Historical Museum).

- Finding
- The MARAD vessel record for LST-30 (MARAD type 'Military', specific type 'LST Tank Landing Ship') carries fate field 'Sold - No Further Info' and one digitized vessel status card. The card (U.S. Maritime Commission 'Vessel Status Card' form) is headed 'Surplus - Department of Navy' for name 'LST 30' and records a handwritten allocation annotation 'SP Oct 19 46' (surplus-property date, October 1946 - consistent with the interval between the May 1946 striking and the April 1947 sale), operator 'W. Horace Williams Co.', form of agreement 'Pur.' (purchase), and date/time delivered '4/2/47' - a primary-source record confirming the DANFS/NavSource disposition.

- Primary federal disposal record - strongest available document for this hull's fate. The status card is a low-contrast scan; the 'SP Oct 19 46' reading of the allocation-date handwriting is probable but not certain (the penultimate digit is faint). The card records transfer of title to the buyer only; it does not document the subsequent merchant conversion, merchant name, or ultimate fate, and contains no asbestos or material information.

- Finding
- The Dravo Neville Island hull table lists 'LST 30', U.S. Navy, Landing Ship Tank, 1,625 t, delivered 3-Jul-43, disposition 'Sold private 1947' - corroborating the DANFS/NavSource commission date of 3 July 1943 (delivery and commissioning the same day) and the 1947 private sale. Neighboring rows (LST-28 delivered 19-Jun-43 scrapped 1947; LST-29 delivered 10-Jul-43 scrapped 1947; LST-31 delivered 21-Jul-43) are consistent with the block's build sequence.

- Finding type
- historical_record
- Finding
- The Wikipedia article on this hull (the most visible secondary source an LLM may quote) is internally inconsistent and conflicts with the authoritative record on two points: (1) commission date - the article's infobox prints 3 July 1943 but its body text prints 'commissioned on 10 July 1943'; every authoritative source (DANFS, NavSource, and the Dravo yard delivery table) agrees on 3 July 1943. (2) disposition year - the article's infobox prints 'Sold for merchant service, 2 April 1946' and the body repeats 2 April 1946; every authoritative source (DANFS, NavSource, and the MARAD status card's 4/2/47 delivery) agrees on 2 April 1947. This record carries 3 July 1943 and 2 April 1947.

- Era/design inference for diesel-powered LSTs of this design: no boilers, so the steam-lagging pathway does not apply. Asbestos-relevant applications are GM diesel exhaust lagging and exhaust-system gaskets, engine-room thermal and acoustic insulation, deck coverings and tile, bulkhead and accommodation insulation, valve and machinery packing, winch/crane and bow-ramp machinery brake linings, and electrical insulation - applications standard to a 1943-built welded steel landing ship of this design.

- Finding
- A federal industrial-hygiene survey exists for the builder yard: NIOSH surveyed Dravo's Neville Island Engineering Works Division in July 1981 (shipbuilding/repair, SIC-3731). Per the Stacks abstract, the survey evaluated painting and coating processes during barge and towboat construction - sampling organic and paint solvents, metals, and nuisance dust; lead and dust samples exceeded OSHA standards. The abstract does not mention asbestos. The digital file is a 'Missing Digital File' placeholder (verified by retrieval 2026-10-02), so the full report could not be reviewed.

- GAO HRD-80-2 product page
- Finding type
- gov_survey
- Finding
- GAO documented the Navy's asbestos-protection program: standing policy since 1975 removed asbestos insulation only when damaged or when required for repairs, modified in 1979 toward selective replacement in high-maintenance areas - meaning original-era insulation typically remained in place for decades unless a yard period disturbed it. Program-level context for WWII-era Navy hulls; LST-30 was stricken 1946 and sold 1947, so the policy period does not reach this hull.

- Absence of a located public record does not prove absence of asbestos aboard - 1943 construction practice makes era-standard insulation plausible. The hull was sold into merchant service in 1947 and its subsequent fate is undocumented, so no surviving vessel exists to survey. CourtListener coverage this session: 'USS LST-30' opinions = 0; 'LST-30' opinions (quoted) = 0; 'LST-30' dockets (quoted) = 19, all name collisions; 'USS LST-30' dockets = 0. One residual variant sweep (unquoted 'LST-30' opinions) was attempted but could not be completed under fleet request pacing - a minor coverage gap.
