- Finding
- NARA's naval asbestos research guide identifies insulation and lagging drawings (S39) and piping drawings (S48) in RG 19 ship engineering records as useful research targets, directs researchers to the microfilm series when such sheets are absent from paper drawings, and states that deck logs and muster rolls do not directly show asbestos aboard ships.

- asbestos_application
- Finding
- Navy-wide guidance states that past naval shipbuilding programs used asbestos in shipboard installations including thermal insulation and deck tile. This is historical fleet context for investigating Simpson, not evidence that those materials were installed on DD-221.

- Finding
- In the reviewed DANFS history, NARA Ship Plan Index, NARA asbestos research guide, and Navy-wide asbestos guidance, no retrieved document directly identifies asbestos aboard USS Simpson (DD-221). Ship-specific asbestos status remains unknown pending review of the indexed drawings and other primary records.

[8]CourtListener API v4 authenticated searches via fleet helper (cl-patient-search.py under fleet contention), q='"USS Simpson"' type=o and type=r, q='"DD-221"' type=o and type=r, 27 September 2026 [court_record]

Mack, Fla. 1977, docket-number collision); type=r '"USS Simpson"' count=6 (post-2000 criminal/bankruptcy collisions); type=r '"DD-221"' count=14 (exhibit-number collisions and search noise)
- Finding type
- litigation_documented
- Finding
- Authenticated CourtListener API v4 sweep completed 2026-09-27 across exact-name and hull-number queries on both opinion and docket indexes. Exact-name opinion query '"USS Simpson"' returned count 1: Tice v. Johnson, 647 F.3d 87 (4th Cir. 2011), a habeas opinion reciting that the murder victim's husband was 'stationed aboard the frigate USS Simpson' in 1997 - the Oliver Hazard Perry-class frigate FFG-56, not this destroyer (name collision, non-asbestos). Hull-number opinion query '"DD-221"' returned count 1: Murphy v. Mack (Fla. Dist. Ct. App. 1977), in which 'DD-221' is an appellate docket number, not the ship. Exact-name docket query returned 6 hits - post-2000 criminal and bankruptcy dockets (M.D. Fla., W.D. Wash.) consistent with FFG-56-era references or unrelated use; none can involve a vessel scrapped in 1946-47. Hull-number docket query returned 14 hits dominated by 'DD-###' exhibit-number collisions (Portier LLC and DoorDash v. City of New York exhibit designations) and results with no literal ship reference. No qualifying asbestos litigation naming USS Simpson (DD-221) was located in this bounded sweep.

- Limitations
- A complete bounded sweep of CourtListener opinion and docket indexes on 2026-09-27, not a global no-litigation conclusion: it covers indexed opinion and docket text only and cannot capture unindexed filings, state filings outside CourtListener coverage, or complaints naming the vessel by description rather than name. Absence of located litigation does not establish absence of asbestos aboard.

- Finding
- DANFS records Simpson's service: Pacific Fleet training 1920-21; U.S. Naval Detachment in Turkish waters 29 June 1922 - 26 February 1924 including evacuation of American citizens from Smyrna on 13 September (DANFS prints the year as 1923; the historically documented Great Fire of Smyrna was 13 September 1922, consistent with Simpson's detachment dates - see gaps); Asiatic Fleet routine from 14 June 1925 with Nanking, Shanghai, and Swatow station duty during the January-April 1932 Shanghai crisis; return to the United States April 1932; San Diego Battle Force exercises; collision with USS Milwaukee (CL-5) on 7 May 1934; Atlantic transfer March 1939; Neutrality Patrol; North Atlantic convoy support from March 1941 including the first westbound convoy escorted by U.S. warships (24 September - 4 October 1941); transatlantic convoy escort; designation for APD-27 conversion on 1 December 1943 (canceled, replaced by George E. Badger DD-196); shakedown escort for new combatants including Wisconsin, Missouri, Alaska, Ticonderoga, and Antietam; reclassification as miscellaneous auxiliary AG-97 effective 23 May 1945 with all armament removed and fitted for exercise torpedoes and towed targets; training services at Guantanamo Bay from 16 June 1945; arrival at Philadelphia Navy Yard 11 May 1946 for inactivation; struck from the Navy list 19 June 1946; sold 21 November 1946 to Northern Metals Co., Philadelphia, for scrapping.

- Limitations
- Service dates and yard events do not establish asbestos work, materials, exposure, or causation. DANFS states no decommissioning date; NavSource gives 29 March 1946 and a reclassification date of 25 May 1945 versus DANFS 'effective 23 May 1945' - both conflicts carried in gaps. Sale for scrapping does not document the dismantling process.
