- Finding
- The official BuShips 1945 data book lists this hull's row: LCS(L)(3)120 built by George Lawley & Sons Corp., Neponset, Mass.; keel laid 4 Nov 44; launched 14 Nov 44; date of first commission 29 Nov 44. The class characteristics table for LCS(L)(3) 1-130 gives: 158'0" o.a., 153'0" w.l., 23'8" extreme beam, 387 tons displacement at limiting draft, trial speed 14.4 knots; armament 3 twin 40mm AA mounts and 10 rocket launchers; main engines 'G. M. Diesel 6051 series 71' at 1,320 shaft hp, single GM main reduction gears, 2 propellers, 2 diesel-driven 60 kW 450 V A.C. ship's-service generators, diesel-oil capacity 635 bbls.

- Primary official source for construction milestones and class specs; contains no asbestos or materials content. The engine model line '6051 series 71' is as printed in the document (likely a misprint for GM/Detroit Series 71 engines - the association spec sheet reads 8 GM diesels, 4 per shaft, 1,600 max bhp; see gaps). The class accommodations row and NavSource's complement figure differ (8/70 vs 6 officers/65 enlisted) - carried in gaps.

- NavSource record for this hull: laid down 4 November 1944 at George Lawley & Sons Corp., Neponset, MA; launched 14 November 1944; commissioned USS LCS(L)(3)-120, 29 November 1944, LT Frederick H. Lamartin USN in command. Assigned Asiatic-Pacific Theater: LCS(L)(3) Flotilla Four (CDR N. Phillips), Group Ten (LCDR J. A. Dodson), Division Twenty. Campaign: Okinawa Gunto operation - assault and occupation of Okinawa Gunto, 17 May to 14 June 1945; one battle star for WWII service; ribbons: American Campaign Medal, Asiatic-Pacific Campaign Medal (1 star), WWII Victory Medal, Navy Occupation Service Medal with Asia clasp. Occupation service in the Far East 2 September 1945 - 20 March 1946. Decommissioned, date unknown. Redesignated LSSL-120, 28 February 1949. Transferred to Japan 30 April 1953, renamed Iwagiku (418); returned to US Navy custody 12 July 1971; struck from the Naval Register, date unknown; 'Final Disposition, fate unknown.' Photo captions include a contemporaneous US Navy photo of the ship 'at Red Beach, Iheya Shima, Ryukyus, June 1945, providing fire support' and a 1958 Yokosuka photo of ex-LSSL-120 as JMSDF Iwagiku (418).

- Finding
- First-person ship-specific account by the first CO: built at 'the George Lawley Shipyard in Hingham, Massachusetts' in fall 1944; fitting out in East Boston; transit via the Cape Cod Canal to the Chesapeake Bay; crew training at the Naval Amphibious Training Base, Solomons, Maryland; availability at Norfolk Naval Station; departed Norfolk 29 December 1944 for San Diego via Key West and the Panama Canal; joined Flotilla Four at San Diego; February 1945 Pearl Harbor staging (LCT escort to Kaneohe; underwater-demolition-team training); April 1945 departure for Okinawa via Eniwetok and Ulithi escorting six ammunition-laden LSTs; arrived Buckner Bay, Okinawa, 19 May 1945; made smoke to screen the fleet, ran suicide-boat patrols, served Radar Picket Station 15 once, and bombarded the shore of Ie Shima with rockets and gunfire supporting a landing there; moved to Leyte Gulf in July 1945; arrived Yokosuka a few days after the surrender signing and spent about seven months on Tokyo Bay support duties including carrying stretcher cases and patrolling inshore of Japanese repatriation ships; left Japan April 1946 with about a dozen LCSs and towed a disabled sister to Eniwetok; mid-ocean casualty when seawater ballast entered a fuel day tank and damaged the propulsion and generating engines (cracked pistons and cylinders); extensive repairs at Pearl Harbor; arrived San Diego June 1946.

- Limitations
- Retrospective first-person memoir hosted by NavSource - valuable ship-specific operational detail but not an official record; the 'Hingham' yard attribution conflicts with the BuShips build table's 'Neponset' (both were Lawley yards - carried in gaps), and 'Ie Shima' vs the USN photo caption's 'Iheya Shima, June 1945' is carried in gaps. Contains no asbestos content. The ballast/fuel casualty is a machinery-space event relevant only as operations context - it is not an exposure record.

The USN class table gives the class machinery as '8 General Motors diesels,' matching the association spec sheet.

- Class spec sheet from the veterans' association that maintains the surviving class hull: 'Engines: 8 GM diesels, 4 per shaft - max. BHP: 1600 twin variable pitch propellers. Also 2 GM diesels, serving as generators for electrical power.' Complement 6 officers, 65 enlisted; length 158'6", beam 23'3"; armament as NavSource. Sister hull LCS(L)(3)-102 survives as the Landing Craft Support Museum ship (ex-HTMS Nakha, returned from Thailand) - the only physically extant unit of the class; the association's renovation photo log documents volunteer rust scraping, painting, and generator work but contains no asbestos or hazmat content.

[7]Era inference built on: NAVSHIPS 250-011 Vol II LCS(L)(3) characteristics (diesel plant, no boilers); National Association class spec sheet; GAO HRD-80-2 program-level finding (see ev-07) [other_primary]

- Finding type
- asbestos_application
- Finding
- A steel-hulled diesel amphibious craft built November 1944 falls inside the Navy's documented asbestos-use era; era-standard applications on a small diesel vessel of this type and period were engine exhaust lagging, piping gaskets and valve packing, electrical insulation and arc shielding, interior bulkhead/deck coverings, and machinery-mounted insulation in confined spaces. As a diesel craft she carried no steam plant - the boiler/steam-line lagging pathway of steam vessels does not apply.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming LCS(L)(3)-120 / LSSL-120 / Iwagiku was found in the public sources searched (see search_ledger). CourtListener returned zero hits for opinions on 'LSSL-120', 'Iwagiku', 'LCS(L)(3)', 'LCS(L)' + asbestos, and 'landing craft support' + asbestos, and zero docket hits for 'LSSL-120', 'LCS(L)(3)-120', and 'Iwagiku'; the unquoted hull query returned only unrelated 'LCS' entity collisions. CAVEAT: the 'LCS-120' opinion variant remained pending at record time - the fleet-wide pacing throttle blocked it; logged as blocked, not as a negative result.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1944 steel vessel of this type is consistent with retained era materials, and the hull's post-1971 disposal is undocumented (no scrapping or preservation record located). Deck logs (NARA RG 24), BuShips General Information Books / construction specs, and the Lawley plans collections are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
