- NavSource is a volunteer secondary compilation, not a primary registry - milestone dates track DANFS where they overlap. 'Sinking the next day' conflicts with DANFS/RN Loss List's 20 February loss date (torpedoed 20 Feb - the foundering date is the nuance; see gaps). Convoy note 'SC122/HX229' names two separate March 1943 convoys - which carried this hull is unresolved (see gaps). Contains no asbestos content.

- uboat.net record for this hull: USS LST 305 ordered 20 May 1942 (secondary-only detail); built Boston Navy Yard; laid down 24 July 1942; launched 10 October 1942; U.S. Navy commissioned 6 December 1942, end of U.S. service 7 December 1942 - 'to the Royal Navy as LST 305'. As HMS LST 305 (RN designation 'LST (Mk 2)' class): commanding officer A/Lt.Cdr. Ronald Maudslay Naylor, RNR, April 1943 - 20 February 1944; sailed in convoy KMS 18A (departed the Clyde 20 June 1943 in an eight-LST group, arrived Gibraltar 29 June 1943) and onward in the KMS 18B/KMF 18 convoy series arriving off Sicily 10 July 1943. Sunk 20 February 1944 by U-230 (Kplt. Paul Siegmann) off Anzio at 41 deg 14 min N, 12 deg 31 min E. The attack entry reconstructs: at 17.55 U-230 fired one GNAT acoustic torpedo that probably detonated at the end of its run; at 18.51 a further torpedo hit and sank HMS LST-305.

- asbestos_application
- Finding
- A 1942-built LST-1-class tank landing ship sits inside the Navy's documented wartime asbestos-use era. Her diesel plant (2 x GM 12-567A, no boilers) removes the boiler/steam-line lagging pathway that dominates steam-vessel exposure; era-standard asbestos-relevant applications aboard this type were diesel exhaust lagging, engine-room thermal/acoustic insulation, gaskets, valve packing, deck coverings, bulkhead and accommodation insulation, machinery packing, and winch/windlass brake linings. Built at a U.S. Navy yard during peak wartime asbestos use.

- Finding
- CORRECTION: the World War II Database (ww2db.com) Battle of Anzio page attributes this hull's sinking to 'Italian motor torpedo boats.' That attribution is contradicted by every consulted source at higher authority: DANFS ('sunk by an Axis submarine off Anzio'), NavSource ('Torpedoed and sunk by German U-boat U-230'), uboat.net's attack reconstruction (U-230, Kplt. Siegmann, 17:55 GNAT miss/18:51 hit), and the MAST Royal Navy Loss List ('sunk by U-boat in Operation Shingle'). The submarine attribution is carried; the E-boat/MTB attribution is rejected.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, material schedule, abatement contract, hazmat disclosure, museum record, or docketed case naming LST-305 was found in the public sources searched (see search_ledger). CourtListener API v4: opinion queries "LST-305", "LST 305", and "USS LST-305" each returned zero results; docket queries "LST-305" and "LST 305" each returned the same single name collision (In re Black Farmers Discrimination Litigation, D.D.C. 1:08-mc-00511 - an OCR-garbled Miami 305-area-code phone number in scanned text). As a hull sunk in action in February 1944, she never underwent postwar overhaul, reserve-fleet lay-up, museum conversion, or scrapping - the processes that generate most asbestos documentation - so the negative finding is structurally unsurprising. Secondary web sweeps surfaced only class-level law-firm marketing material asserting asbestos aboard LST-type ships without primary sourcing - excluded by source policy.
