[2]Weber v. John Crane, Inc., 143 Cal. App. 4th 1433, 50 Cal. Rptr. 3d 71 (Cal. App. 1st Dist., Div. 1, No. A111421, Oct. 18, 2006); review denied Cal. Supreme Court Jan. 3, 2007 (S148309) [court_record]

- Opinion, Background section (para. beginning 'Plaintiffs argued in the trial court...' citing Weber deposition) and Conclusion ('The judgment is reversed')
- Finding type
- litigation_documented
- Finding
- Published appellate opinion names this hull: plaintiffs alleged Joseph Weber suffered mesothelioma from asbestos exposure over nearly 40 years as a machinist, equipment operator, and laborer; the opinion recites deposition testimony that Weber 'had worked as a machinist aboard the USS Hanson for four years, beginning in 1960,' with work that 'included repacking valves with a grayish white gasket material and putting packing back in pumps that had been disassembled,' and that witnesses were deposed who 'identified John Crane, presumably in connection with a product used on the Hanson.' The court reversed summary judgment for John Crane, holding the defendant had not met its initial burden of producing evidence that plaintiff could not establish causation. During 1960-1964 the only commissioned USS Hanson was DD-832, so hull attribution is solid.

- Joseph Weber (USN machinist aboard USS Hanson, c. 1960-1964); engineering-space crew
- Limitations
- Deposition-stage exposure recital inside an appellate burden ruling - exposure aboard this hull is alleged/recited, never adjudicated; the opinion identifies no specific asbestos product aboard and does not quantify asbestos content. Judgment reversed and remanded posture; subsequent merits history (retrial/settlement) not located. Weber died May 10, 2006 during the appeal.

- DANFS record for this hull: launched 11 March 1945 by Bath Iron Works Corp., Bath, Maine; commissioned 11 May 1945, Comdr. John C. Parham; Caribbean shakedown, then conversion to picket destroyer at Boston Navy Yard; Pacific occupation duty 1946; Atlantic Fleet Norfolk Feb 1947; designated DDR-832 8 March 1949; Korea (Inchon Sept 1950, Hungnam/Wonsan evacuation cover Dec 1950, combat cruises Sept 1951-May 1952 and Dec 1952-July 1953); annual 7th Fleet deployments incl. Formosa Strait patrol during the 1958 Quemoy-Matsu crisis; redesignated (as 'DW-832', typographical for DD-832) spring 1964 and entered Mare Island shipyard for Fleet Rehabilitation and Modernization conversion, completed 6 December 1964; Vietnam service with DesRon 11 from 1965, incl. 1966-67 deployment firing over 9,000 5-inch rounds; eight Korean War battle stars.

DANFS does not state the laid-down date (1944-10-07 rests on NavSource/secondary compilations) and prints 'DW-832' for the 1964 reversion to DD-832. The DDR-832 designation date (8 Mar 1949) conflicts with secondary compilations (18 Mar 1949) - conflict carried in gaps. Mirror transcription cited because the live NHHC page returns 404.

- Finding
- Reported trial verdict naming this hull: plaintiff counsel reports a San Francisco jury awarded $2,999,543 on December 9, 2003 to Philip Hoeffer, a retired Navy electrician (1950-1955) with pleural mesothelioma who served aboard ARD-29, USS Hanson (DDR-832), and USS Yorktown, with alleged exposure to asbestos-containing phenolic plastic parts (Rostone molded components in Westinghouse, Cutler Hammer, and Allen Bradley electrical equipment) abraded during maintenance. If accurate, this is a trial-level verdict - a more advanced litigation stage than the Weber pleading recital.

- Omnibus Opinion and Order, ECF No. 171 (quotation of class engineering drawing and expert insulation tally)
- Finding type
- asbestos_application
- Finding
- Published federal omnibus opinion recites class-level asbestos documentation for this hull's class: 'an engineering drawing for the insulation and lagging of forced draft blower turbines for the class of destroyers (DD 692, USS Allen M. Sumner class), within which the USS Harlan Dickson fell, specifies the use of amosite felts and asbestos cloths,' and quotes a report estimating 'a partial tally of the weight of the asbestos-containing thermal insulation and lagging products in the fire ... and engine rooms of a ship belonging to the USS Allen M. Sumner (DD 692) and USS Gearing (DD 710) classes of destroyers is 30.3 tons.' Hanson (DD-832) is a Gearing-class destroyer within the quoted class scope.

- Era/design inference for this hull: a Gearing-class destroyer built 1944-45 with a high-pressure superheated steam plant (4 Babcock & Wilcox boilers, GE geared turbines, 60,000 shp) at the peak of Navy asbestos use would have carried period-standard boiler casing and fireroom insulation, steam-line lagging, turbine lagging, valve and flange gaskets and packing, fireproofing, and deck coverings. Documented yard periods at era-documented yards (Bath Iron Works build; Boston Navy Yard picket conversion 1945; Mare Island FRAM conversion 1964) are events during which insulation work/disturbance occurred under era practice.

- Finding
- Asbestos dust hazards were being formally investigated at this hull's builder yard during the hull's own construction window (laid down Oct. 7, 1944 - delivered May 11, 1945): the Dec. 19, 1944 USPHS investigation concerned 'asbestosis from amosite pipe covering at Bath Iron Works,' and the Jan. 18, 1945 report addressed the 'asbestos hazard' at the yard. The wartime survey program culminated in Fleischer et al. (1946), the influential pipe-covering epidemiology study of two Navy yards and two Navy contract yards.

- Limitations
- Yard-level and program-level documentation, not a hull record - the surveys measure shop/yard conditions at the builder during the construction window, not materials installed aboard DD-832. Fleischer 1946 anonymized surveyed yards (A/B/C/D); the Bath-specific documents are field reports enumerated in the retrospective's bibliography. The 1946 study's exculpatory conclusion ('not a dangerous occupation') is now discredited - documented in the retrospective.

- Locator
- GAO HRD-80-2 product page and description
- Finding type
- gov_survey
- Finding
- GAO documented the Navy's asbestos-protection program: standing policy (1975) removed asbestos insulation only when damaged or when required for repairs, modified 1979 to selective replacement in high-maintenance areas - meaning original-era insulation typically remained in place for decades unless a yard period disturbed it. Hanson served 1945-1973 (pre-1975-policy era) and spent 1973-2004 in ROCN service outside the US program.

- No ship-specific asbestos survey, abatement contract, hazmat disclosure, or ACM inventory for DD-832 was located in the public sources searched. The litigation sweep produced exactly one qualifying published opinion naming the hull (Weber v. John Crane, 2006 - deposition-stage recital) and one reported-but-unverified trial verdict (Hoeffer, 2003); no docketed RECAP case names DD-832/DDR-832. The hull is gone (expended as a target 2006), foreclosing museum-condition documentation.
