- Finding
- NavSource record for this hull: CLASS - GLEAVES, as built; displacement 2,395 tons (full), 348'4" oa x 36'1" x 13'2" max; armament 4x5"/38AA, 6x0.5" MG, 10x21" tt (2x5); machinery 50,000 shp, Westinghouse geared turbines, 2 screws; 35 kt; range 6,500 nm at 12 kt; crew 208. Building data line reads 'Laid down by Boston Navy Yard June 1 1940' - a typo inconsistent with the same page's launch line (25 May 1940); destroyerhistory.org and uboat.net independently carry 1 June 1939 (laid down with Meredith, DD-434). Fate: damaged beyond repair by Japanese warships off Kolombangara 13 July 1943, scuttled by torpedoes from Ralph Talbot (DD-390); NavSource casualty line reads '71 of her crew were lost' vs DANFS 'two officers and 59 men' (61) - variance carried in gaps. Photo caption documents the Mare Island overhaul window 12/19/42-2/7/43. CO list: Cdr. John Martin Higgins (15 Jan 1941 - 24 Oct 1942), Lt. Cdr. John Benjamin Fellows Jr. (24 Oct 1942 - 13 Jul 1943). uboat.net adds: ordered 1 October 1938; loss position 07 deg 41 min S, 157 deg 27 min E; 61 killed, 15 wounded, 214 survivors including both officers named, rescued by Ralph Talbot.

- Finding
- Official BuShips damage-summary entries name this hull three times. First-year summary (17 Oct 1941 - 7 Dec 1942): 'GWIN (DD433) - 11/15/42 - Guadalcanal - Gunfire - 2 - Projectile struck starboard side just below main deck, frames 124 and 190 - moderate machinery damage.' Second-year summary, Ships Damaged: 'GWIN (DD433) DD423-type - 6/30/43 - Rendova Strait, Solomon Islands - Gunfire - 1 - A 5-inch common projectile struck at frame 129, port side. Minor fragment damage. Torpedo warheads penetrated by fragments.' Ships Lost: 'GWIN (DD433) DD423-type - 7/13/43 - Kula Gulf, Solomon Islands - DD Torp - 1 - Plunged by stern - Struck by deep-running Japanese destroyer torpedo on port side at frame 150. Severe flooding aft. Remained afloat for 7 hours - finally sunk by U.S. forces.'

- Limitations
- Documents battle damage to machinery spaces (frame-150 torpedo hit amidships is consistent with DANFS's engine-room hit) and the loss sequence - an engineering record, not a materials record; it does not identify insulation or asbestos content. The 15 November 1942 damage date independently confirms the Guadalcanal action dating implied by DANFS.

- Finding
- A ship-specific official document exists for this hull in NARA-held 12th Naval District records: a Supplementary Damage Report covering the 15 November 1942 Solomon Islands (Naval Battle of Guadalcanal) damage, typed by Mare Island Navy Yard, with 24 photographs and 2 damage plates. This is the repair-yard documentary trail for the documented December 1942 - February 1943 Mare Island overhaul.

- Limitations
- Index/finding-aid entry only - the report's content was not retrieved (oversize plates require NARA scanning service; the index is a commercial researcher's catalog of the NARA record). A damage report documents structural/machinery damage and repairs, not necessarily insulation materials; whether it itemizes asbestos-containing material is unknown until pulled. Not an asbestos finding.

[6]Consolidated era inference - Bureau of Ships, Ships' Data U.S. Naval Vessels Vol. 1 (Jan 1945) destroyer machinery table (shipscribe.com scan) + Atlas shipyard dataset Boston Naval Shipyard record (evidence_tier 3) + class profile benson-gleaves-class [other_primary]

- Finding type
- asbestos_application
- Finding
- Era/design inference: DD-433 is a 1939-41 Boston Navy Yard-built destroyer of the peak Navy asbestos era, with 4 superheated boilers (class figures 575 psi/700 deg F) and geared steam turbines of ~50,000 shp (NavSource identifies Westinghouse turbines for this hull; BuShips table lists 47,000 shp for class lead DD-421 - class-range discrepancy unresolved). Typical period applications for this plant: boiler casing and fireroom insulation, steam-pipe and turbine lagging, valve/flange gaskets and packing, deck tile, accommodation insulation, fireproofing. Builder Boston Naval Shipyard is documented at yard level in the Atlas dataset (tier 3: John Crane gaskets and sealing materials per In re John Crane, Inc., Tex. App. 2003). Overhaul yard Mare Island Naval Shipyard is documented at yard level (tier 2: Kaylo, Unibestos, Marinite, Transite, Careytemp, Gold Bond, packing, gaskets), though that yard record's dated evidence clusters postwar and does not reach this hull.

- Class/era and builder-yard inference only - no ship-specific finding. Typical applications establish typicality of design, not installation aboard this hull; no quantities, no individual exposure, and no product identification for DD-433. Mare Island yard-level product documentation post-dates the 1942-43 overhaul window.

- Finding type
- litigation_documented
- Finding
- No qualifying asbestos litigation located naming this hull as of 2026-09-27. Exact-name 'USS Gwin' sweeps and 'DD-433' hull-number sweeps against the opinion and RECAP docket indexes were attempted this session and repeatedly blocked by the shared fleet pacing budget; the classification rests on (a) the 2026-09-16 class-profile sweeps on 'USS Benson'/'USS Gleaves' (0 asbestos-litigation hits) and (b) the absence of any non-marketing secondary claim naming DD-433. Law-firm 'Navy ship asbestos lists' do name USS Gwin (DD-433) alongside DD-71 and DD-772/DM-33 - excluded per source policy; such lists are marketing claims asserting no adjudicated fact.

- Limitations
- Negative finding is provisional: the session's own CourtListener sweeps were pacing-blocked and are logged 'pending' in the search ledger - this row must be reclassified if a later sweep surfaces a hit. 'Gwin' collides across three hulls (DD-71, DD-433, DD-772/DM-33) and a common surname; any future hit requires hull-attribution review. RECAP/opinion indexes are not exhaustive; absence of located litigation does not mean none exists.
