- Finding type
- gov_survey
- Finding
- The Navy's 1979 response reproduced in the GAO report describes thermal insulation on machinery, equipment, and piping as a major asbestos application in Navy ships, and also identifies other general shipboard applications. This is Navy-wide period context only.

- U.S. Navy shipbuilding and ship repair program
- Limitations
- This is not a record about LSM-27 or its class and cannot establish that any asbestos-containing material was installed aboard this vessel. It does not establish material quantities, individual exposure, causation, or what remained at disposal.

[4]National Archives, Researching Asbestos aboard U.S. Naval Vessel up through 1961 (last reviewed 2 Mar. 2022) [other_primary]
- Locator
- Sections 'Bureau of Ships General, Confidential, and Secret Correspondence' and 'Cartographic Branch (Includes Blueprints & Engineering Drawings)'
- Finding type
- historical_record
- Finding
- The National Archives research guide explains that documenting asbestos aboard a particular naval vessel requires hull-specific research. It identifies Bureau of Ships correspondence and hull-numbered engineering drawings, including S39 insulation and lagging and sometimes S48 piping drawings, as research avenues.

- Limitations
- NAVSEA's PDF is live but returned HTTP 403 when opened through available direct and browser fetches; indexed text was available in search results. The table does not spell out the ship name, explain 'MAP,' establish a decommissioning date, or identify subsequent fate. Hull-number correspondence is recorded cautiously; this row is not asbestos evidence.

[6]United States v. Robles, No. 2:09-cr-00001 (C.D. Cal. filed Jan. 5, 2009), CourtListener docket 5756474 [court_record]
- Locator
- CourtListener search result and docket API record 5756474; docket caption and number
- Finding type
- litigation_documented
- Finding
- An authenticated exact-hull CourtListener docket search returned United States v. Robles, a 2009 C.D. California criminal docket. The case caption and docket number identify unrelated litigation; the query hit is a name collision, not asbestos litigation involving USS LSM-27.

- Limitations
- This is a bounded search result, not proof that no records exist. CourtListener exact-name opinion/docket searches and exact-hull opinion search returned no results. The exact-hull docket search returned one unrelated criminal case (United States v. Robles), classified as a name collision/other litigation, not asbestos litigation. NARA hull-specific Bureau of Ships files, engineering drawings, and non-digitized records were not reviewed.
