- DANFS record for this hull: built by the Boston Naval Shipyard; sponsored by Mrs. Ann Guest Walsh, granddaughter of Commodore John Guest (namesake, 1822-1879); commissioned 15 December 1942, Comdr. Henry Crommelin in command. Shakedown at Guantanamo Bay; Casablanca convoy escort April-May 1943; 3d Fleet Pacific service - Bougainville landings (1 Nov 1943), Green Island operations incl. the depth-charge attack on I-171 completed by Hudson (DD-475), Kavieng bombardment, Marianas invasion (Saipan 15 Jun 1944, Philippine Sea, Guam 21 Jul 1944), Anguar bombardment and rescue of 52 Perry survivors (12-13 Sep 1944); San Francisco Bay overhaul from 25 Oct 1944; Iwo Jima (19 Feb 1945); Okinawa (27 Mar-1 Jul 1945, undamaged kamikaze glance-off 25 May); plane guard off Honshu; arrived Puget Sound Naval Shipyard 15 Nov 1945; decommissioned San Diego 4 Jun 1946; reserve until transferred on loan to Brazil 5 Jun 1959, serving as Pará (D-27). Eight WWII battle stars. Spec block: 2,050 t, 376'6", 35.5 kt, cpl. 329, cl. Fletcher.

- DANFS documents service history and specifications, not materials or asbestos content. The mirror transcription dates the launch to 27 September 1941 - the date every other source gives as keel laying; launch was 20 February 1942 (documented in gaps). Mirror transcription cited because the live NHHC page returns 404.

- Finding type
- vessel_history
- Finding
- Disposal record for this hull: transferred on initial five-year loan at Bremerton, Washington, 5 June 1959; commissioned into the Brazilian Navy as Pará (D-27), arriving Rio de Janeiro 22 December 1959. On 1 August 1973 she was stricken from the U.S. Navy list and acquired outright by Brazil (NGB). Brazilian service included UNITAS exercises and a 13 February 1976 collision with Mato Grosso (D-34); stricken by Brazil 21 August 1978. Used as a practice target 1982-83 - including the first Brazilian Exocet MM-38 firing by a Niterói-class frigate - then sunk by two torpedoes from submarine Ceará (S-14) ~80 miles south of the Cabo Frio lighthouse. NavSource dates the sinking 23 February 1983, 19:28 local, position 24 deg 23'16" S / 42 deg 24'27" W; NGB dates it 22 February 1983 - conflict carried in gaps.

Neither addresses materials aboard; the sinking means no present-day in-place material question exists.

[4]Fletcher-class machinery design (4 Babcock & Wilcox boilers, 2 geared steam-turbine sets, 60,000 shp, 2 shafts - navypedia + BuShips Ships Data 1945 per class profile) + Atlas shipyard dataset, Boston Naval Shipyard record (evidence_tier 3; John Crane gasket/sealing-material litigation identification) [other_primary]

- Finding type
- asbestos_application
- Finding
- Era/yard inference: a WWII Fletcher-class destroyer with a four-boiler 60,000-shp steam plant would have carried period-standard asbestos insulation, lagging, gaskets, packing, and fireproofing; builder Boston Naval Shipyard (Charlestown) is documented at yard level in the Atlas dataset (tier 3), including litigation identification of John Crane gasket/sealing-material exposure at the yard. NavSource's as-built block lists Allis-Chalmers turbines for this hull while the Brazilian NGB record lists G.E. - the maker conflict is carried in gaps; the four-B&W-boiler/60,000-shp plant is consistent across sources.

- Finding type
- gov_survey
- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - placing this hull's 1941-42 construction and her entire U.S. service period (1942-46) inside the documented asbestos-use era.

- Locator
- Opinion, service-records recital (Tex. Crim. App. No. 31338)
- Finding type
- litigation_documented
- Finding
- Published appellate opinion naming this hull - NOT asbestos litigation. In a murder appeal, the court recites that the appellant's excluded Navy service records 'show that on July 15, 1943, he boarded U.S.S. Guest and while attached to the U.S.S. Guest operating in the Pacific War Theatre participated in five named campaigns.' A court-documented service recital confirming a crew member aboard DD-472 in the Pacific from 15 July 1943; the vessel reference is incidental to a criminal-evidence ruling. Caught only by the punctuated variant query 'U.S.S. Guest' - the 'USS Guest' opinion query returns 0.

- Thomas Vernon Carpenter (appellant; crew member aboard DD-472 from 1943-07-15 per excluded service records)
- Limitations
- Non-asbestos criminal appeal (DWI-resulting-in-death indictment, murder conviction affirmed). The ship reference is a recited service-records fact, not an adjudicated finding about the vessel; it establishes crew presence aboard this hull in 1943 but nothing about materials, conditions, or exposure.

- Finding
- No qualifying ship-specific asbestos record located for DD-472: no hull ACM survey, abatement contract, hazmat disclosure, or qualifying litigation names this hull in the public sources searched (see search_ledger). The hull's 1983 sinking as a target forecloses any present-day survey/abatement pathway.
