    NavSource documents this hull's timeline: LSM-1 class Landing Ship Medium laid down 23 Dec 1944 at Brown Shipbuilding Co., Houston TX; launched 13 Jan 1945; commissioned USS LSM-379 on 10 Feb 1945, LT William J.

    Builder context: Brown Shipbuilding Co. was created in 1941-42 by George and Herman Brown of the Brown & Root construction company, building the Greens Bayou Fabrication Yard at the juncture of the Houston Ship Channel and Greens Bayou with approximately $9M in Navy funding; it became the second-largest Houston-area wartime employer and used sideways-launching slips on the narrow bayou. Brown built 254 of the 558 LSMs between May 1944 and March 1946 in the blocks LSM-1 through LSM-125, LSM-354 through LSM-388, and LSM-459 through LSM-552 - LSM-379 falls in the 354-388 block.

    Era/yard-program documentation, not a hull record: yards are anonymized and no vessel or type is named. LSM-379 was diesel-driven with no boilers or steam propulsion plant, so the pipe-covering applications this source documents were less extensive aboard her than aboard steam vessels; the source supports era-consistent possibility of asbestos applications (gaskets, packing, paneling, insulation where fitted), not ship-proven presence, quantity, or individual exposure.

    Absence of a located public record does not prove absence of asbestos aboard - a 1945 hull retaining original fabric is era-consistent with asbestos-containing materials, though a diesel-driven hull carried less of the canonical insulation than steam ships. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.
