- DANFS record for this hull: laid down 17 July 1939 by the Charleston Navy Yard, S.C.; launched 7 August 1940; sponsored by Mrs. Alice Gertrude Gordon Grayson Harrison, widow of Rear Admiral Cary Travers Grayson; commissioned 14 February 1941, Lt. Comdr. Thomas M. Stokes in command. DesDiv 22 Atlantic Fleet; DesRon 11 flagship in the Caribbean out of Guantanamo Bay from 28 August 1941; North Atlantic neutrality patrol between Newfoundland and Iceland from 26 October 1941. Pacific from April 1942: Hornet escort for the Doolittle raid (launched 18 April); Guadalcanal landings cover 7 August; Eastern Solomons 24 August (two planes downed, a third damaged); 25 August five depth-charge attacks on a surfaced Japanese submarine; ~8 months in the Guadalcanal area (Noumea convoys, Slot patrol, radar picket, rescue work); 18 October 1942 picked up 75 survivors of USS Meredith (DD-434) and helped escort the fuel/ammunition barge-tug Vireo to Guadalcanal. Pearl Harbor overhaul from 15 April 1943; barge actions off Kolombangara evacuations 30 September - 3 October (DesRon 21); Puget Sound Navy Yard overhaul from 16 December 1943. Majuro 10 February 1944; Pityilu Island (Admiralties) assault support 30 March; fighter-director ship Tanahmerah Bay 22-24 April; bombarded Biak 27 May and Noemfoor 2 July; TG 38 Palau strikes from 1 September; Okinawa/Philippines strike series from 2 October; 15 October rescued 194 men of torpedoed USS Houston (CL-81). Saipan radar-picket/lifeguard from 3 November; Seattle 9 June 1945. Post-war: Panama Canal 8 October; Charleston 16 October 1945; decommissioned at Charleston 4 February 1947, placed in reserve and berthed at Orange, Tex. Bracketed addendum: 'Grayson was struck from the Navy list 1 June 1971 and sold 22 November' (sale year unstated). Thirteen battle stars for World War II service.

- Limitations
- DANFS documents identity, builder, specifications, service history, and disposition - it contains no materials or asbestos content. The bracketed addendum's sale date carries no year ('sold 22 November'), and its 1 June 1971 striking date conflicts with the NHHC Online Library (February 1971) and NavSource-derived secondary sources (1 June 1972) - carried in gaps rather than reconciled. The DANFS entry does not mention the hull's pre-construction name assignment (Livermore); the 23 December 1938 swap is documented in the DANFS Livermore (DD-429) entry. Mirror transcription cited because the live NHHC page returns 404.

- Finding
- NHHC Online Library record for this hull corroborates and supplements DANFS: commissioned February 1941; Atlantic neutrality patrols/convoy escort before the war; Pacific from April 1942 (Doolittle raid); escorted Enterprise during the Guadalcanal/Tulagi invasion and the Battle of the Eastern Solomons 'in which she suffered light damage and some casualties from Japanese air attack'; 18 October 1942 rescue of Meredith survivors and recovery of the abandoned tug Vireo; 17 February 1943 helped repel an enemy torpedo-plane attack on a Guadalcanal-bound convoy; mid-1943 stateside shipyard work; October 1943 barge battles off Kolombangara; Admiralties and northern New Guinea amphibious assaults spring-early summer 1944; Palau invasion September 1944; present mid-October 1944 when the torpedoed cruisers Houston and Canberra were towed out of danger off Formosa; central-Pacific patrol/rescue through May 1945; overhauled June-August 1945; Charleston for Navy Day October 1945; decommissioned February 1947, Reserve Fleet more than two decades. Disposition per this source: 'stricken from the Naval Vessel Register in February 1971 and was sold for scrapping in November 1972' (page title range '1941-1972'). Tin Can Sailors data block adds call sign NEKW ('L'il Audrey') and disposition: 'Sold 11/22/1972 to Southern Scrap Material Co., LTD., New Orleans, LA for $73,000.00. Scrapped.'

- Limitations
- NHHC Online Library is official NHHC content (via ibiblio mirror) but its disposition figures (stricken February 1971; sold November 1972) conflict with the DANFS bracketed addendum (struck 1 June 1971; sold 22 November) - the two NHHC products disagree with each other. Tin Can Sailors is a reputable veterans-association secondary source; its 22 November 1972 sale to Southern Scrap Material Co. ($73,000) independently converges with the DANFS/NHHC sale window but conflicts with NavSource's 'sold June 12 1974' - conflicts documented in gaps, not resolved. No asbestos or materials content in either source.

- Finding type
- asbestos_application
- Finding
- Era/yard inference: this hull is a Gleaves-subclass member of the Benson/Gleaves machinery family - 4 superheated boilers (575 psi/700F per BuShips Ships' Data 1945 for the class) driving geared turbines at ~50,000 shp - built 1939-41 at the peak Navy asbestos era. Period-standard applications: boiler casing and fireroom insulation, steam-pipe and turbine lagging, valve/flange gaskets and packing, fireproofing, deck coverings. Builder Charleston Navy Yard (Atlas charleston-naval-shipyard, tier 2) has documented asbestos product classes in yard use including pipe insulation at 5-50% asbestos content and spray-on insulation 'for walls and ship interiors'; the documented December 1943 - early 1944 overhaul was performed at Puget Sound Navy Yard (Atlas tier 1; 1970 DTIC study documents 40-150 f/cc during insulation rip-out there). Documented yard windows: Charleston NY construction/fitting-out 1939-41; California repair period April-May 1942 (yard unspecified); Puget Sound Navy Yard overhaul December 1943 onward; Seattle-area overhaul June-August 1945; Charleston inactivation October 1945 - February 1947.

- Limitations
- Class/era and builder-yard inference only - nothing in this row establishes that any specific asbestos product was installed aboard DD-435, in what quantity, or that any individual was exposed. Yard-level documentation is yard-not-hull evidence; the 1970 Puget Sound study postdates this hull's 1943-44 yard period by ~26 years; the Charleston yard product list is not dated to her 1939-41 construction. NARA GIB retrieval not performed.

- Finding
- No qualifying asbestos litigation naming this hull located: 'USS Grayson' opinion search returned 0 hits; 'DD-435' opinion search returned 0 hits; 'USS Grayson' RECAP docket search returned 1 hit - Bergstrom v. United States Navy, No. 2:21-cv-00055 (W.D. Wash., filed 15 January 2021, terminated 3 August 2022) - classified OTHER LITIGATION (non-asbestos): an Administrative Procedure Act records-correction/medals action in which the plaintiffs sought a posthumous Navy Cross and correction of the service record of their father, Capt. Edward Bergstrom, a WWII naval officer; 'USS Grayson' text sits in the certified administrative record (ECF No. 39 attachments, 10 U.S.C. 1552 application file), i.e., a service-history reference, not an exposure allegation. DD-435 was the only commissioned USS Grayson, so exact-name coverage is close to exhaustive for indexed text (USS Grayson County LST-1039 is a 1955 county-namesake hull - distinct-name collision risk noted; 'Grayson' surname collisions are a documented class).

- Limitations
- Sweep covers CourtListener-indexed opinion and RECAP docket text only; un-indexed dockets, state-court filings, and non-digitized records are outside coverage, and absence of located litigation does not mean none exists. The 'DD-435' RECAP docket sweep and 'aboard the Grayson'/'U.S.S. Grayson'/contextual queries were deferred by the fleet-wide pacing gate (shared ~114/hr budget) - logged as blocked in the ledger; Bergstrom classification rests on the published order recitals (posthumous-medals APA posture), not on a read of the sealed-volume administrative record.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1939-41 steam destroyer sits inside the Navy's peak asbestos era and the era inference stands on its own. The hull was scrapped; no surviving artifact or museum record exists to inspect. Does not establish or defeat any individual claim of exposure or legal eligibility.
