    Finding
    Decided summary-judgment order in NYCAL: plaintiff John D. Eylers alleged mesothelioma from asbestos insulation on M.T. Davidson pumps during Navy service 1956-1958 aboard USS Chukawan (AO-100) and USS Denebola (AF-56). His April 10, 2018 deposition testimony described ~2 months aboard Denebola in 1958 as a seaman apprentice making deliveries ship-wide, observing people replacing insulation on gaskets in the engine room and firemen cleaning out boilers, removing soot, and 'working on the asbestos insulation.' Defense expert Clancy Cornwall's review of plaintiff's declassified U.S. Navy records identified one M.T. Davidson pump aboard Denebola - a 30-gpm distiller brine pump in the engine room - which he averred operated below 125 deg F and under U.S. Navy specifications would have carried no external insulation. The court granted SLM's CPLR 3212 motion: mere presence of M.T. Davidson pumps aboard was insufficient to establish actual exposure from that defendant's product; all claims and cross-claims against SLM severed and dismissed (NON-FINAL disposition; claims against remaining defendants continued).

    Seaman apprentice aboard AF-56 ~2 months in 1958 (alleged bystander exposure)
    Limitations
    Decided-motion record at the discovery/summary-judgment stage - exposure content is plaintiff deposition allegation, not an adjudicated finding. The disposition is a merits-level negative for this plaintiff as to this defendant's product: the only product-identified equipment aboard (one M.T. Davidson distiller brine pump) was averred uninsulated under Navy specs, and the court held presence of the pumps insufficient to establish exposure. Does not establish that asbestos exposure occurred aboard this hull; equally does not establish that asbestos was absent - deposition testimony described insulation work the court did not weigh for other defendants. Uncorrected slip opinion, not selected for official publication.

    Finding
    Pleading-stage federal asbestos action: the First Amended Complaint in Hall v. Aqua-Chem, Inc. alleged the plaintiff's asbestos exposure 'may have occurred between 1959 and 1977' aboard seven named vessels including 'the USS Denebola AF-56 from 1959-61' (also USS Cadmus AR-14, USS Mauna Loa AE-8, USS Edmonds DE-406, USS Enterprise CVA(N)-65, USS Truxton CVAN-35, USS Milwaukee AOR-2) and various naval shipyards. The district court denied Crane Co.'s Rule 12(b)(6) motion, holding the vessel-specific allegations gave defendants ample notice to build a defense.

    Population
    Sailor alleged aboard AF-56 1959-1961
    Limitations
    Pleading allegation - a complaint's vessel list is an allegation, not a finding, and AF-56 is one of seven hulls named for a multi-decade career. The 12(b)(6) denial tests pleading sufficiency only and says nothing about exposure aboard this hull. Order text not retrieved from a primary source; the denial is documented through the quoted order language in secondary reporting plus the court's own administrative case list confirming the docket. PACER/CM-ECF pull remains the open lead.

    Finding
    Board of Veterans' Appeals remand naming this hull: a veteran's service-connection claim for restrictive respiratory disorder 'as due to inservice exposure to asbestos' recorded Navy service aboard eight ships including 'U.S.S. Denebola from 1963 to 1964' (one of four ships the decision characterized as World War II era). Citing M21-1 provisions that chrysotile, amosite, and crocidolite 'were used extensively in military ship construction' during WWII, the Board REMANDED for development - directing the RO to determine 'whether it is as likely as not that the Veteran had asbestos exposure in the Navy' and, if necessary, to request ship logs from the Navy and National Archives. No exposure determination was made.

    Limitations
    Administrative remand with no finding - the Board ordered development precisely because exposure had not been determined; the vessel name appears in the veteran's service history, not in any adjudicated exposure finding. The M21-1 'WWII era ships' framing is era-level policy language applied to a hull that is in fact 1944 wartime construction. Does not establish exposure aboard, quantity, or legal outcome (remanded claims may be granted or denied later; no later decision located).

    DANFS entry: the second Denebola (AF-56) was launched 10 June 1944 as Hibbing Victory by Oregon Shipbuilding Co., Portland, Oreg., sponsored by Miss J. A. Bush; transferred to the Navy 1 May 1952; converted at New York Naval Shipyard; commissioned 20 January 1954, CDR S. E. Ramey in command. From completion of shakedown through June 1960 she alternated eight tours of duty with the 6th Fleet in the Mediterranean with local operations out of Norfolk, participated in NATO exercises in 1957 and 1958, carried stores to the Caribbean, served as plane guard for President Eisenhower's plane returning from the 1957 Paris NATO conference, and replenished ships patrolling off Beirut in the aftermath of the 1958 Lebanon crisis.

    Finding
    Naval Historical Center photo-archive narrative extends the record past DANFS: after 1954 shakedown (Guantanamo Bay), a midshipman training cruise to Ireland, and an Atlantic Fleet exercise, in January 1955 Denebola began an operational routine that continued 'some two decades' - two to four annual Mediterranean trips provisioning Sixth Fleet units, interspersed with Atlantic/Caribbean fleet support and occasional shipyard repair and overhaul. In 1963 a helicopter landing platform was added aft, enabling vertical replenishment in addition to alongside high-line transfer. She left active service at the end of April 1976, a few months after her final Mediterranean cruise, and was sold for scrapping in December of that year.

    Conversion event: the Navy acquired the laid-up Victory ship in May 1952 and converted her to a refrigerated provisions store ship.

Shipscribe class notes document SCB Project No. 57 (approved by CNO 1950-10-27 for the R2-S-BV1 design, applied to two VC2-S-AP3 hulls), George G. Sharp of New York producing contract plans and specifications (submitted 1951-11-14), names DENEBOLA/REGULUS and designations AF 56/57 approved 1951-12-15, and a conversion contract concluded with Todd Shipyards Corp. - a discrepancy with DANFS's New York Naval Shipyard attribution that is logged rather than resolved.

    The conversion is ship-specific and documented; its asbestos scope is NOT documented - any removal or installation of asbestos-containing insulation during the 1952-54 conversion is inference, not record. Conversion-yard attribution is unresolved (DANFS New York Naval Shipyard vs. shipscribe's Todd Shipyards contract note - both may reflect contract-vs-performance split; NARA captions place the ship at NYNSY at commissioning). shipscribe is a reputable secondary compilation of official characteristics data, not a primary record.
