The yard was Navy-funded ($9M, built 1941 by George and Herman Brown at Green's Bayou / Houston Ship Channel) and produced 254 LSMs among 359 vessels in four years.

[6]Consolidated era inference - BuShips SDB-1945 v2 machinery data (diesel direct drive, 2,800 shp, Fairbanks Morse engines for the LSM 1-145 block) + era amphibious-ship construction practice; consistent with the lst-1-class class profile treatment in this dataset [other_primary]

- Finding type
- asbestos_application
- Finding
- Era/design inference for diesel-powered WWII landing ships: the LSM-1 class had no boilers or steam plant, so the steam-lagging pathway does not apply; asbestos-relevant applications consistent with 1944 amphibious construction are diesel exhaust lagging and gaskets, engine-room thermal/acoustic insulation, deck coverings/tile, bulkhead and accommodation insulation, machinery packing, and winch/crane brake linings.

- Finding
- Litigation surface check: exact-name searches returned zero opinions and zero RECAP dockets for 'USS LSM-6'. The single 'LSM-6' opinion hit is Cates v. United States (S.D. Fla., Dec. 24, 1969; cluster 8792840), a personal-injury suit arising from a transfer accident aboard USS Nimble - the court uses 'LSM-6' as a small-landing-craft size reference ('no vessels smaller than an LSM-6'), not this hull, and the case is not asbestos litigation. Classified NAME COLLISION / other litigation. The 'LSM-6' RECAP docket query returned 11 hits - all NAME COLLISIONS on metadata: criminal, bankruptcy, and commercial dockets (e.g., United States v. Perez Gonzalez, flsd; Lehman Brothers Holdings, nysb; Winn-Dixie Stores, flmb; Pitts v. LStar Development Group, nced; Royal Insurance v. Zygo, ctd; Webb Candy v. Walmart, mnd) where 'LSM-6' matches a token inside docket documents, with no maritime, Navy-vessel, or asbestos nexus in any case caption or court. No qualifying asbestos litigation naming this hull was located.

- Limitations
- Absence of located dockets does not prove no suit was ever filed - unindexed state-court filings and settled/unreported matters are outside this surface. Cates classified on opinion text (PI matter, craft-type reference). The 11 RECAP hits were classified as collisions on case-name/court metadata without per-docket full-text pull - if any were re-reviewed, the underlying docket entries should be inspected for the matching token. Does not establish or defeat any claim of exposure or legal eligibility.

The hull has no DANFS entry (NHHC covers only post-1955-named LSMs; the HyperWar index carries LSM-6 as a non-linked row), and the MARAD Vessel History Database holds no card for it despite the 1946 Maritime Commission disposal custody.
