   Limitations

   NavSource is a volunteer-compiled secondary reference, not a primary registry - its milestone dates are corroborated here by shipbuildinghistory.com's yard table (ev-02) and uboat.net (ev-03). The same page contains a conflicting caption line attributing 'JDS Akane' to USS LSSL-98; the page's own timeline block and both corroborating sources tie Akane to hull 100 (LSSL-98 became JDS Aoi per the yard table). Decommission and striking dates are not stated ('date unknown'). No asbestos or materials content.

   Finding

   Commercial Iron Works yard table lists yard hull no. 212 as 'LCS(L) 100', US Navy landing craft, 250 LDT / 159 ft, delivery 9-Feb-45, disposition 'To Japan 1953 as Akane, returned 1958, sunk as target 1958'. Yard context from the same page: Commercial Iron Works was started November 1916 by William T. Casey, Otto J. Hoak and Robert Boogs on a 30-acre site just south of the Ross Island Bridge, Portland; it closed in 1946 after building 188 boats during WWII; the site was later sold to Zidell Marine.

Hull 100's own documented campaign credit was the later Okinawa Gunto assault-and-occupation window, 18-30 June 1945.

   A filed interrogatory exhibit enumerates wartime industrial-hygiene surveys of Navy-contract shipyards, including item 22: 'Industrial Health and Safety Re-Survey Commercial Iron Works, Portland, Oregon at 13 (March 16-19, 1945)' - alongside surveys of Bath Iron Works (1942), Oregon Shipbuilding (1942), Willamette Iron & Steel (1943 and 1945), Albina Engine & Machine Works (1945), Federal Shipbuilding (1944), and others. Establishes that this hull's builder underwent a government industrial health and safety re-survey dated within weeks of the hull's 13 February 1945 commissioning.

   Limitations

   Discovery-stage exhibit listing, not the survey itself: the filing enumerates the document but does not reproduce its findings, so the survey's asbestos content is unverified from this source. Yard-level (builder), not hull-level. Heathman is a Texas asbestos products case unrelated to this vessel - the exhibit is used only to establish that the March 1945 CIW survey exists.

    Limitations

    Absence of a located public record does not prove absence of asbestos aboard - and this hull was sunk as a target in 1958, so no extant material survives to survey in any case. Deck logs (NARA SL-44 listing) and the March 1945 CIW industrial-health re-survey remain undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
