- Direct HTTP checks, 2026-10-01: history.navy.mil pattern returns 404; web.archive.org/cdx/search/cdx?url=history.navy.mil/research/histories/ship-histories/danfs/l/lsm-26* returns empty array; ibiblio.org/hyperwar/USN/ships/dafs/LSM/lsm26.html and lsm26.htm both 404; nvr.navy.mil/SHIPDETAILS/SHIPSDETAIL_LSM_26.HTML redirects (302) to NVR homepage

- Finding
- Live verification on 2026-10-01: history.navy.mil returns HTTP 404 on every current DANFS URL pattern tried for LSM-26, including the path pattern that resolves for other hulls (e.g., /research/histories/ship-histories/danfs/l/[hull].html and the /content/history/nhhc/... variant). No Wayback Machine (web.archive.org) CDX capture exists for any history.navy.mil DANFS URL variant for LSM-26. The ibiblio.org hyperwar DANFS mirror, used successfully elsewhere in this project as a DANFS text mirror, has individual pages only for a small subset of LSM hulls (e.g., LSM-373, LSM-312) that did something independently notable; direct hull-number URL guesses for LSM-26 on that mirror returned 404. No NVR (nvr.navy.mil) ship-detail page resolves for this hull either — hull-number URL patterns redirect to the NVR homepage.

- Limitations
- This row documents absence of an official NHHC/DANFS/NVR record, not absence of the ship or its service — identity and movements are independently corroborated elsewhere (ev-02). Absence of an official record does not establish or defeat any asbestos claim; it means this record cannot cite a primary Navy document for the ship's administrative history.

- Source chain is a commercial 1997 veterans'-association compilation transcribed by a private enthusiast archive, not an NHHC/DANFS/NARA primary record — disclosed here rather than mislabeled. The administrative facts (dates, theater, decommissioning/striking/scuttling) are standard WWII Navy record-keeping content, internally consistent, and independently corroborated by cross-referencing multiple separate secondary compilations (search-engine synthesis of NavSource and uboat.net Allied Warships) with no discrepancies found for this hull. Contains no asbestos, materials, or condition information and supports no asbestos claim.

- Finding type
- asbestos_application
- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII generally, the era and program under which this hull was built, driven by wartime demand for fire protection and insulation materials across ship types.

- Limitations
- Program/era-level scholarly documentation of asbestos use in WWII shipbuilding generally; does not name this vessel, this ship type, or the diesel-propulsion small-craft category specifically, and does not establish that asbestos was or remains aboard this hull, nor quantity, location, condition, exposure, or causation. This hull's diesel propulsion (no boiler plant) means the steam-plant insulation scope this article's discussion most directly supports does not apply here.

- Finding type

- Finding
- No qualifying ship-specific asbestos litigation located. CourtListener (authenticated, via required helper): opinions search for the exact phrase "USS LSM-26" returned zero results; opinions search for "LSM-26" combined with "asbestos" returned zero results; dockets search for "LSM-26" returned one hit, Monsanto Company v. Syngenta Seeds Inc. — an unrelated agricultural-patent case, a name/string collision, not an asbestos case and not naming this ship.

- Limitations
- Absence of a located case does not prove absence of any exposure aboard this hull - it means no qualifying litigation record was found in the collections CourtListener indexes. Does not establish or defeat any exposure claim or legal eligibility. One additional planned query (opinions, "LSM-26" + asbestos as a second pass) and the docket query both initially hit the fleet-wide pacing throttle and were completed on retry later in the same session; no query was abandoned.

- Finding
- Archival lead (not retrieved - no box-level search performed, no spend authorized): NARA RG 19 (Records of the Bureau of Ships) holds construction-contract and plans files for WWII-built small combatants including LSM-type hulls; RG 38 (Records of the Office of the Chief of Naval Operations) holds WWII war diaries and action reports; RG 24 (Records of the Bureau of Naval Personnel) holds deck logs. These are the standard record groups for a hull of this type and era; existence of asbestos-specific material for LSM-26 within them is unknown until surveyed in person.
