- DANFS record for this hull: 'The first Hart (DD-110) was launched 4 July 1918; by Union Iron Works of San Francisco, Calif., sponsored by Mrs. Daniel C. Nutting; and commissioned 26 May 1919, Comdr. Harold Jones in command.' Characteristics block: (DD 110; dp. 1,191; l. 314'5"; b. 31'9"; dr. 9'2"; s. 34 k.; cpl. 113; a. 4 4", 12 21" tt.; cl. Wickes). Named for Midshipman Ezekiel B. Hart (killed in action on Lake Ontario 26 August 1814) and Lt. Comdr. John E. Hart (died of fever in the Mississippi River 11 June 1863, commanding Albatross, West Gulf Blockading Squadron).

- vessel_history
- Finding
- DANFS service record: 'Hart joined the destroyer force and operated off the California coast until 17 July 1920, when she was reclassified minelayer, destroyer, DM 8, and proceeded to Mare Island Navy Yard for installation of minelaying equipment. Following her conversion, Hart was assigned to Mine Detachment, Asiatic Fleet, and sailed for the Philippine Islands in November 1920. She subsequently operated in waters off the Philippine Islands and China in peacetime operations.'

She decommissioned 1 June 1931 and her name was struck from the Navy List 11 November [1931]. Hart was sold for scrap 25 February 1932 in accordance with the London Treaty for the limitation of naval armaments.' NavSource adds the buyer: sold to Learner & Rosenthal, Oakland, Cal., and broken up for scrap.

- Machinery and register data from NavSource's DM-8 page citing Ships' Data, U.S. Naval Vessels (1921 edition): keel laid 8 January 1918 (NavSource destroyer index reads 1 January 1918); propulsion 'Four White-Foster boilers, two 12,100shp Parsons turbines, two shafts' with the 1921 update 'Four Yarrow boilers and two 28,700shp Curtis geared turbines'; complement 103 (1921: 122); armament four 4"/50, two 1-pounders (1921: one 3"/23 replacing the 1-pounders), 12 x 21" torpedo tubes; 1921 trial speed 33.97 knots. NavSource classifies the build as 'WICKES (LITTLE)' - the Bethlehem-designed subtype built at Bethlehem-controlled Union Iron Works.

- Limitations
- NavSource is a secondary compilation transcribing official Ships' Data editions - quoted values are attributed to the 1921 edition but the underlying page images were not independently examined (image-scan PDF retrieved; no text layer). Machinery figures conflict between the initial block and the 1921 entry (White-Foster/Parsons vs Yarrow/Curtis, 24,200 vs 28,700 shp) - both carried, discrepancy in gaps. Establishes steam-plant configuration relevant to era insulation practice; contains no asbestos statement.

- Finding
- Peer-reviewed state-of-the-science review documents that amosite and chrysotile asbestos were used extensively as insulating materials aboard U.S. naval ships 'beginning in the 1880s and continuing well into the 1950s' for incombustibility, low thermal conductivity, light weight, and strength; suppliers followed government specifications prescribing asbestos content in insulation, gaskets, packing, and similar materials. This hull's entire existence - construction 1918-19, commission 1919-1931, scrapping 1932 - falls inside the documented window; the 1920 Mare Island conversion would have followed period Navy specifications.

- Finding
- CourtListener API v4 opinion-index sweep (2026-09-26, authenticated, fleet-paced): 'USS Hart' returned 0 hits - a clean negative for the opinion index; no published opinion names this vessel. 'DD-110' returned 17 hits, all name collisions (New York Appellate Division family-court matters - token collisions on the hyphenated number; none involve a vessel, the Navy, or asbestos). 'DM-8' returned 45 hits, all name collisions (Texas Attorney General opinions on DM-series docket numbers, unrelated federal/state cases, a 'Hartner' surname token; none involve a vessel, the Navy, or asbestos). 'U.S.S. Hart', docket-index (type=r), and Hart/asbestos queries were enumerated but repeatedly rate-limited by the fleet-wide pacing budget - queued for backfill; see search_ledger for executed vs blocked queries. Known collision discipline for this name: the second USS Hart (DD-594, Fletcher class, in commission 1944-1946) is the hull any 'USS Hart' asbestos claim would more likely reference, and 'Hart' is a high-frequency surname/party name (Hart-Schaffner-Marx, common captioned-party collisions).

- Opinion-index coverage is not exhaustive: unreported trial-level filings, RECAP-only dockets, and pre-1950 district admiralty matters are thin in the index, and the docket-index sweep was not completed. Absence of an opinion is not absence of litigation; no zero-litigation conclusion is made. If hits are located later, hull attribution is mandatory - 'USS Hart' in post-1944 context likely refers to DD-594 unless the opinion names DD-110, DM-8, or 1919-1931 service dates.

The hull was scrapped in 1932 and no preservation, museum, or underway-use phase ever generated hazmat documentation for it. Ship-specific asbestos documentation remains unknown.

- Bounded public-source negative finding, not proof of absence: a 1918 steam-turbine destroyer is era-consistent with asbestos insulation, but no hull-specific record was located. The ship's early scrapping (1932) predates asbestos-awareness documentation regimes - absence of a record here is expected, not probative. Does not establish that asbestos was or was not present aboard.

A Wickes & Clemson class Booklet of General Plans dated 1 October 1919 (RG 19 'Plans for Flush Deckers' file unit, digitized on the Internet Archive) documents class-level arrangement but names no insulation material.

- DD-594 characteristics block + construction paragraph
- Finding type
- historical_record
- Finding
- Disambiguation boundary: the second USS Hart (DD-594, Fletcher class) is a different hull - laid down as Mansfield, renamed Hart 21 March 1944, launched 25 September 1944 at Puget Sound Navy Yard, commissioned 4 November 1944; served Okinawa and Borneo; decommissioned 31 May 1946 and remained in the Pacific Reserve Fleet into 1967. Any 'USS Hart' litigation, exposure claim, or asbestos reference dated after 1944 or naming Fletcher-class characteristics refers to DD-594 unless DD-110/DM-8 is explicitly named. The ships' namesakes also differ: DD-594 was renamed for Lt. Comdr. John E. Hart alone.
