Houghton USN in command; WWII assignment Asiatic-Pacific Theater, LSM Flotilla Sixteen / LSM Group Forty-Seven / LSM Division Ninety-Three; decommissioned (30 March 1947 per this extract - see conflicts); laid up in the Reserve Fleet; struck from the Naval Register 22 December 1952; authorized FY 1953 for conversion to Coastal Mine Layer; converted at Marine Basin Co., Brooklyn, NY, 27 February - 20 November 1953; transferred to Greece 1 December 1953 as HS Amvrakia (N-05); US designation changed to MMC-7 1 October 1960; decommissioned by the Greek Navy 2002. Radio call sign NVIR. Awards: American Campaign Medal, Asiatic-Pacific Campaign Medal, World War II Victory Medal. Specs: 520 t light / 743 t landing / 1,095 t full; 203'6" oa; 34'6" beam; 13.2 kts; 5 officers + 54 enlisted + troops (2 off / 46 enl); one twin 40mm, four single 20mm; 2 x GM 16-278A diesels, 1,440 BHP each @ 720 rpm, direct drive, twin screws, 2,800 shp.

- Limitations
- Volunteer secondary compilation, not a primary registry; its milestones generally track official records but its decommission date (30 Mar 1947) conflicts with four other sources (10 May 1947 - see gaps). Source extract is from Turner Publishing's LSM-LSMR Amphibious Forces Vol. II, not DANFS - LSM-303 has no DANFS entry. Contains no asbestos content. Internal inconsistency: prose calls Houghton 'ENS' while the CO table lists 'LT'.

- Documented for this hull (MMC-7 row): Greek AMVRAKIA, reclassified (1953), NSY Charleston, keel 8 Oct 1944, launched 14 Nov 1944, conversion completed 20 Nov 1953; US strike 22 Dec 1952; US disposal 1 Dec 1953 (transfer). Ship notes: 'FY 1953 (MDAP). Ex LSM 303 (comm. 6 Jan 1945, decomm. 10 May 1947). Converted by Marine Basin Co., Brooklyn, NY, 27 Feb 1953 to 20 Nov 1953. Decomm. by Greece 2002.' Class notes: nine late LSMs were converted for transfer under the Mutual Defense Assistance Program; 'the converted LSMs were all stricken by the USN before being transferred, but they remained in the Naval Vessel Register (NVR) as LSM's in MDAP loan status'; MMC numbers were assigned in place of LSM designations effective 1 Oct 1960 (this hull -> MMC-7). Conversion particulars: two minelaying rails on the former vehicle deck; four booms (two forward, two aft) for loading mines; redesigned topside crowded with AA guns; a Greek source gives the Greek ships' capacity as 100-130 mines. Sister conversion documented: Aktion (ex-LSM-301, MMC-6) decommissioned by Greece 27 Feb 2001 and broken up.

The date column value (14 Nov 1944) equals the hull's launch date; the file likely covers the commissioning packet period.

The article repeats the US timeline (decommissioned 10 May 1947, stricken 22 Dec 1952, conversion Brooklyn 27 Feb - 20 Nov 1953). NavSource's photo block includes official Hellenic Navy photographs of N-05 underway (c.1959, c.1968, c.1970) and a Corinth Canal transit.

- asbestos_application
- Finding
- A diesel-powered LSM-1-class hull built in late 1944 at Charleston Naval Shipyard sits inside both the Navy's documented asbestos era (asbestos shipboard use through the early 1970s per GAO) and a builder yard with an extensively documented asbestos product inventory. Era-standard applications aboard a small diesel amphibious ship of this period were thermal insulation, machinery and diesel-exhaust lagging, gaskets, valve packing, electrical insulation, and interior fireproofing/finish materials. As a direct-drive diesel ship she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply, but construction, repair, and the 1953 minelayer conversion all created disturbance pathways, and the confined small-ship volume applies.

- Finding
- This hull's builder is a documented asbestos yard in the Atlas shipyard dataset: Charleston Naval Shipyard's record enumerates asbestos product categories used at the yard (pipe insulation at 5-50% asbestos content, boiler coatings at 15%, spray-on insulation 'for walls and ship interiors,' gaskets, packing, and related products) and carries a documented 1988 OSHA inspection citation under the federal asbestos standard plus two documented multi-million-dollar mesothelioma verdicts tied to the yard (2014, 2018). The ship was built, launched, and commissioned at this yard in late 1944 - January 1945.

- Yard-level documentation, not a hull record: documents asbestos conditions and product use at Charleston Naval Shipyard generally - no source names LSM-303's materials. The OSHA inspection is from 1988, four decades after construction; the yard verdicts are yard/worker-level litigation, not ship findings. OSHA establishment detail page returned HTTP 403 to automated fetch (access gap); inspection data carried via the Atlas yard record. Does not establish materials aboard this hull, individual exposure, or quantity.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum/environmental record, or verified litigation naming USS LSM-303 / MMC-7 / HS Amvrakia was found in the public sources searched (see search_ledger). No DANFS entry exists for this numbered LSM (NHHC 404s; the NavSource history derives from the Turner Publishing extract). No NVR detail page exists (hull disposed 1953, pre-1987 cutoff; nvr.navy.mil also unreachable from this network). CourtListener opinion searches: 'USS LSM-303' returned 0 results; 'LSM-303' returned 15 hits, each individually reviewed - all name collisions (OCR noise, docket numbers, unrelated Texas/other cases), zero qualifying asbestos litigation. CAVEAT: CourtListener docket-level coverage is incomplete - the loose docket query returned ~1,000 token-collision results (none vessel-related in reviewed pages) and the quoted docket query plus 'Amvrakia' opinion query were still queued when the fleet pacing budget closed the session window.

- Absence of a located public record does not prove absence of asbestos aboard - a 1944 hull built at a documented asbestos yard and operated 49 years in a foreign navy plausibly retained era materials through her 2002 disposal, but no ship-specific record establishes this either way. Docket-level litigation search is an open gap (paced, partially run). Does not establish or defeat any claim of exposure or legal eligibility.
