    litigation_documented
    Finding
    Published federal opinion names this hull: asbestos product-liability action by Arnold L. Pritt and Ruth A. Pritt against John Crane Inc. The opinion recites that Arnold Pritt 'served in the United States Navy aboard the USS Purdy as a machinist mate from December 1961 to August 1964'; that 'he installed compressed asbestos sheet gaskets and removed and replaced John Crane valve and pump packing in the engine room of the USS Purdy'; that both tasks 'exposed him to the asbestos dust contained in John Crane's products,' sold without warning labels; and that he was diagnosed with malignant mesothelioma in September 2019. Procedural path: filed November 2020 in Massachusetts Superior Court (Middlesex County) against John Crane, Air & Liquid Systems Corp., General Electric Co., and Viacom CBS Inc.; removed December 2020; amended complaint April 2021 solely against John Crane (negligence, breach of express/implied warranties, loss of consortium). John Crane's motion for summary judgment on the government-contractor defense (Boyle) was DENIED - genuine factual disputes found on the MIL-STD-129/MIL-SPEC warning-label issues.

    Limitations
    Stage discipline: this is a summary-judgment DENIAL - the ship-specific service and product recitals are the plaintiff's allegations recited on the motion record, not adjudicated exposure findings; denial means the claim proceeded, not that it was proven. DD-734 is the only USS Purdy ever in commission - a single-ship name, so the 1961-64 service recital attaches to this hull without collision risk. Does not establish asbestos content beyond the products described, quantities, other locations, causation findings, or legal eligibility. CourtListener cluster ID derived from the syfert.com 'cl-9734015' mirror tag (CourtListener API was fleet-pacing blocked at research time); opinion text verified word-for-word via the vLex full-text mirror of 636 F.

    Finding type
    litigation_product_id
    Finding
    Product identification tied to this hull from the published opinion's recital of the record: during Pritt's years aboard USS Purdy (1961-64), John Crane sold the Navy a gasket designated symbol 2150, titled 'Asbestos Sheet, Compressed (Gasket Material),' manufactured under MIL-A-17472 (which incorporates MIL-STD-129 marking requirements and specifies asbestos fiber with natural or synthetic rubber binders and mineral fillers); and the valve and pump packing he handled was described in MIL-P-17303C, 'Packing Materials, Plastic Metallic and Plastic Nonmetallic,' whose plastic non-metallic packing requirements 'listed asbestos as a component.' The opinion recites that Pritt installed such compressed asbestos sheet gaskets and removed and replaced such packing in Purdy's engine room.

    Finding type
    litigation_documented
    Finding
    Disposition record for the Purdy litigation: after Arnold Pritt's death (26 December 2022) the action continued for Ruth Pritt as executrix; on 11 July 2023 Magistrate Judge Bowler allowed in part a second amended complaint - holding general maritime law applies (not the Jones Act or DOHSA), a survival claim could proceed, but loss-of-consortium and punitive-damages claims were unavailable; jury trial was then set for December 4, 2023. Pretrial rulings included denial of John Crane's motion to strike plaintiffs' expert Captain Francis Burger (Navy shipbuilding/specifications) and a mixed ruling on the defendant's 'empty chair' Navy/non-party motion in limine; a plaintiff interlocutory appeal was dismissed by the First Circuit for lack of jurisdiction. A defense-side litigation tracker reports that after eight days of testimony the jury deliberated one day and returned a verdict for John Crane on 23 May 2024.

    Merits-level outcome classified per the less-final-stage rule: the reported defense verdict is a merits-level NEGATIVE for the plaintiffs - the exposure claim was fully adjudicated and rejected; it is not exposure evidence and does not establish or defeat asbestos presence aboard this hull. The verdict report is from a defense-firm case tracker (Goldberg Segalla asbestos case tracker, via JD Supra) - a law-firm source not carried as an evidence citation; the verdict is flagged UNVERIFIED against the docket pending CourtListener RECAP access (fleet pacing at research time).

The report would document the bomb's path, internal explosion damage, structural repairs, and by inference any insulation/fireproofing disturbed; 'Typed by Mare Island' also suggests the 1945 San Francisco-area repair was performed at Mare Island (the yard that typed the report), though no located source names the repairing yard.

    Finding
    CourtListener sweep for this hull: the exact-phrase OPINION query "USS Purdy" returned zero documents - notable given that Pritt v. John Crane Inc., 636 F. Supp. 3d 253 (which recites 'USS Purdy' repeatedly) exists as CourtListener cluster 9734015, indicating the opinion's full text is not hit by that search form (an indexing/tokenization limitation logged for the QA pass, not evidence of absence). The Pritt litigation is confirmed ship-specific by independent full-text retrieval (vLex mirror) and a CourtListener-cluster mirror tag. Name-collision exposure is nil on the ship name: DD-734 is the only USS Purdy ever in commission (single-ship name).

    Limitations
    Partial coverage only: exact-phrase opinion sweep completed (0 hits - see indexing caveat); unquoted 'Purdy', 'Pritt', 'DD-734' (both types) and the type=r docket sweep for 'USS Purdy' remained blocked by the fleet-wide pacing budget at session end across multiple spaced retries (~90 minutes) - docket-level records naming this hull are NOT ruled out. The Pritt docket (D. Mass. 1:20-cv-12270) and any First Circuit appeal docket are unverified on RECAP.
