- Documented for this hull: launched 6 April 1944; commissioned USS LCI(L)-742 26 April 1944 (LTjg. F. J. Geiger, USNR, in command as of May 1945); reclassified LCI(G)-742 31 December 1944; reclassified LCI(M)-742 30 April 1945; assigned to the Asiatic-Pacific Theater in LCI Flotilla Fourteen (CAPT. T. W. Rimer), LCI Group Forty (LCDR. H. Brown); campaigns: southern Palau Islands 6 Sep-14 Oct 1944, Iwo Jima 19 Feb-3 Mar 1945, Okinawa Gunto 1-7 Apr 1945; three battle stars plus retroactive Combat Action Ribbon (Iwo Jima); decommissioned 17 June 1946; struck (date unknown); sold 10 January 1947; registered 1948 as fishing barge Manana, Los Angeles, moved to Redondo Beach, CA, 1949; scrapped 1955. Specifications: 246 t. light / 419 t. loaded; 158'5.5" x 23'3"; two sets of 4 General Motors 6051-series-71 diesels, 4 per shaft; twin variable-pitch propellers, 2,320 shp.

- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - its laid-down entry (20 May 1944) postdates launch and commissioning and is internally inconsistent (see ev-07); its 'LCI Division Seventy-Nine' and group-flagship annotation differ from the NHHC 1 May 1945 fleet organization (Division 80, no flagship mark - see ev-02 and gaps). Contains no asbestos content. The 1955 scrapping predates modern ACM-handling regulation; no hazmat or material record for the breakup was located and the scrapping location is unrecorded.

Geiger (USNR)' as of 1 May 1945 - corroborating the hull's mortar conversion (reclassified LCI(M)-742, 30 April 1945), her commanding officer, and her flotilla/group assignment.

[4]Shipbuilding History (Tim Colton), Commercial Iron Works yard production list - hull no. 117 'LCI(L)-742, US Navy, landing craft, 246 tons, 159 ft, Mar 1944, struck 1946'; yard history block [other_primary]

- Finding
- Builder's production list corroborates this hull: Commercial Iron Works yard number 117 = LCI(L)-742, a 246-ton 159-foot landing craft for the US Navy; the list's 'Mar 1944' build-period month and 'struck 1946' disposition are consistent with the NavSource commissioning window (26 April 1944) and decommissioning (17 June 1946). Yard history: Commercial Iron Works was founded November 1916 on a 30-acre site south of the Ross Island Bridge, Portland, built 188 boats during WWII, closed 1946, and the site was sold to Zidell Marine as a ship dismantling facility.

These name the facilities where the hull was physically converted: Pearl Harbor for the LCI(G) conversion (effective 31 December 1944) and Naval Repair Base San Diego for the LCI(M) conversion (effective 30 April 1945).

Shipyard conversion events are the relevant disturbance pathway for era materials but no asbestos content is stated for these conversions. URL verified live 2026-09-30.

- Finding type
- asbestos_application
- Finding
- A diesel-engined LCI-351-class landing craft built in 1944 at a WWII emergency yard sits squarely inside the Navy's documented asbestos-use era. Era-standard asbestos applications aboard small diesel craft of this type and period were diesel exhaust insulation and lagging, machinery and piping gaskets and valve packing, electrical cable insulation, and joiner/bulkhead insulation and deck coverings. As a diesel craft she carried no steam plant - the boiler and steam-line lagging pathway of larger combatants does not apply; the relevant pathways are machinery-space insulation and the small enclosed compartments of a 158-foot hull.

- State regulatory documentation of asbestos at the builder's former yard: DEQ records the site (the WWII-era Ironworks/Commercial Iron Works shipyard, purchased by Zidell in 1946) as having dismantled 336 ships over 30 years with scrap waste used as site fill; lists 'Asbestos' among site contaminants in groundwater, upland soil, and riverbed sediment; and documents a 2010 'Asbestos abatement project - all workers certified, air monitoring, bulk ACM disposal' as part of the upland remedial action under the 2005 Record of Decision.

- Zidell shipbreaking workforce (1946-1976); remediation workers (2010-2012)
- Limitations
- Site-level environmental record for the builder's former yard only: the asbestos documented reflects decades of shipbuilding and shipbreaking contamination at the site (dominated by Zidell's 1946-1976 shipbreaking operation). It does not establish that asbestos from LCI(L)-742 or any named vessel is present - the hull was scrapped in 1955 at an unrecorded location, likely not Portland given her Southern California registration as Manana. No hull attribution.

[8]NavSource 'Laid down, 20 May 1944' entry for this hull (150742.htm) checked against its own launch (6 April 1944) and commissioning (26 April 1944) entries and against Shipbuilding History hull-117 'Mar 1944' build period [other_primary]

- Finding
- CORRECTION: NavSource records this hull as 'Laid down, 20 May 1944' - a date that postdates her recorded launch (6 April 1944) and commissioning (26 April 1944) by seven weeks. Keel laying cannot follow launch; the 20 May 1944 entry is internally inconsistent and is not carried in this record's laid_down field. The actual laid-down date is not documented in the sources located (sister Commercial Iron Works hulls show roughly 4-6 weeks between laydown and launch, implying an early-1944 laydown, but no source states it).

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - the 1944 construction and WWII service are era-consistent with asbestos-containing materials. CourtListener coverage caveat: vessel names inside complaint bodies (e.g. MDL-875 exposure allegations) are not full-text indexed, so zero name hits does not exclude unadjudicated pleading-stage allegations. Does not establish that asbestos is or is not present; does not establish or defeat any claim of exposure or legal eligibility. Deck logs and conversion work packages (NARA) are undigitized leads.
