[1]DANFS, Seawolf II (SSN-575) - updated entry: construction at Electric Boat, sodium-to-PWR reactor conversion, documented Mare Island Naval Shipyard drydock conversion 1971-1973 [nhhc_danfs]

- Finding
- Documented for this hull: second nuclear-powered submarine and only liquid-metal (sodium-cooled, S2G) reactor ship; laid down 7 September 1953 by General Dynamics Corp. (Electric Boat Co. Division), Groton, Conn.; launched 21 July 1955 (sponsor Mrs. W. Sterling Cole); commissioned 30 March 1957, Comdr. R. B. Laning. Returned to General Dynamics 12 December 1958 for refueling and conversion of her power plant from sodium-cooled to pressurized-water-cooled reactor; out of commission until 30 September 1960. Entered drydock at Mare Island Naval Shipyard 8 January 1971 for overhaul and conversion to a special-project platform; remained until 21 June 1973, then Bangor, Wash.; returned to Mare Island 4 September 1973 and into August 1974 was still operating from that port.

- Limitations
- Ship-specific history only; no asbestos or material content. The documented 1971-1973 Mare Island drydock conversion is a genuine prolonged yard availability - relevant because several litigation plaintiffs (Halseth 1970-76; McIntyre 1963-95; Cronin late-1980s list) claimed Mare Island work - but DANFS establishes presence, not asbestos disturbance. The Leonard allegation's early-1960s Mare Island window is NOT corroborated: DANFS places the hull at Groton for reactor conversion until September 1960 and then on fleet operations.

[2]Leonard v. CBS Corporation (General Dynamics), No. 2:12-cv-60177-ER (E.D. Pa., MDL-875), Order, ECF No. 63 (dated 2014-01-28, filed 2014-01-29; Robreno, J.) [court_record]
- Locator
- ECF No. 63 at 1-2 (vessel list), 6-9 (analysis and order)
- Finding type
- litigation_documented
- Finding
- Merits-level summary-judgment record naming this hull. The order recites that plaintiff John Leonard alleged asbestos exposure 'while working at the Mare Island Naval Shipyard during the early 1960s' and that 'the alleged exposure pertinent to Defendant General Dynamics occurred during Mr. Leonard's work aboard: USS Darter, USS Skipjack, USS Flasher, USS Nautilus, USS Seawolf'. The court granted General Dynamics summary judgment on ALL claims: (1) strict product liability barred - 'a Navy ship is not a "product"' (Mack v. General Electric Co.); (2) negligence - 'Plaintiffs have no evidence that any of the insulation aboard any of the ships at issue (whether original or replacement insulation) contained asbestos'; the co-worker declaration showed dust exposure from insulation but no asbestos-content proof, and expert Ay's asbestos-insulation testimony covered only ships he had worked on, not Leonard's ships; (3) the government-contractor defense 'need not' be reached.

- John Leonard (Mare Island Naval Shipyard worker, early 1960s, alleged)
- Limitations
- This is a merits-level NEGATIVE for the Leonard plaintiffs' claims against General Dynamics, not exposure evidence: the court found no evidence that insulation aboard the named ships (including this hull) contained asbestos, and made no finding that asbestos was or was not aboard. The vessel list is a recital of the plaintiff's allegation. For this hull the early-1960s Mare Island window is not corroborated by DANFS (reactor conversion at Groton through September 1960; fleet operations thereafter).

[3]Speck v. 3M Company, No. 3:20-cv-05845-JD (N.D. Cal.), Order Re Summary Judgment, ECF No. 475 (filed 2024-04-05; Donato, J.) [court_record]
- Locator
- ECF No. 475 at 12-13 (General Dynamics analysis)
- Finding type
- litigation_documented
- Finding
- Merits-level summary-judgment record naming this hull. The order recites as undisputed 'that General Dynamics built three submarines -- the USS Seawolf, USS Thomas Edison, and USS Flasher -- in Connecticut between 1953 and 1966, which Speck worked on in California in the 1970s and 1980s.' The court granted General Dynamics' summary-judgment motion because plaintiffs 'have not identified evidence from which a jury could conclude that Speck was "actually exposed" to asbestos from equipment that General Dynamics placed on those ships' - plaintiffs recited expert qualifications and general conclusions but pointed to no actual evidence of exposure caused by General Dynamics.

Does not establish asbestos aboard this hull; establishes that General Dynamics built her in Connecticut 1953-1966 and that Speck worked on her in California in the 1970s-1980s (consistent with her documented 1971-73 Mare Island availability).

- ECF No. 41 at 1-3 (statement: MINSY work history incl. 'USS Seawolf'; holding: DENIED)
- Finding type
- litigation_documented
- Finding
- Pretrial order in an asbestos products-liability action recites that plaintiff Edward McIntyre (mesothelioma) worked at Mare Island Naval Shipyard December 1963 - June 1995 on construction and overhaul of fast-attack nuclear submarines, 'including painting insulation and pumps,' specifically 'the USS Abraham Lincoln, USS Barb, USS Guardfish, USS Haddock, USS Patrick Henry, USS Permit, and USS Seawolf,' and that he claimed 'the work of overhauling Warren Pumps' products caused the disturbance and release of asbestos dust and fibers into areas where McIntyre worked.' Warren Pumps' summary-judgment motion (government-contractor defense + no product-contact evidence) was DENIED - the court found triable issues of fact on both grounds.

- A denial of summary judgment is a ruling that triable issues existed - NOT a finding that exposure occurred, that Warren Pumps products contained asbestos aboard this hull, or that any material was present. The exposure account is the plaintiff's claim recited by the court; the merits were never adjudicated in the located record. Consistent with this hull's documented 1971-73 Mare Island availability.

- Era inference: a one-off nuclear submarine built 1953-57 at Electric Boat in the peak asbestos era, with a documented 1958-60 reactor-conversion yard period and a documented 1971-73 Mare Island drydock conversion, would era-typically have carried asbestos-containing insulation, gaskets, and packing around propulsion and auxiliary machinery; both documented yard periods are disturbance windows of the kind in which era insulation was installed and removed.
