    DANFS entry for Crater (AK-70): lead ship of the Crater class, named for a Southern Hemisphere constellation, only Navy ship to bear the name. Spec block: dp. 4,023; l. 441'6"; b. 56'11"; dr. 28'4"; s. 12 k.; cpl. 198; a. 1x5", 1x3". Launched as John James Audubon 8 October 1942 by Permanente Metals Corp., Richmond, Calif., under a Maritime Commission contract; sponsored by Mrs. M. E. C. Wetzel; transferred to the Navy 22 October 1942; commissioned 31 October 1942, Lt. Comdr. R. Dodd, USNR, in command. Service narrative: cleared San Francisco 10 Nov 1942, cargo to Efate and Espiritu Santo, New Hebrides, and Noumea, New Caledonia; Wellington, NZ 28 Jun 1943 to repair and reload; cargo from New Zealand and other supply bases to Guadalcanal and throughout the Solomons until 21 Jun 1944; Marshalls and Marianas through summer 1944; returned to Guadalcanal, southwest Pacific operations until 1 Mar 1945, then overhaul at San Francisco; west-coast cargo to Samar, P.I.; departed 26 Jul for Auckland; cargo from Auckland and Brisbane to Saipan, the Philippines, Manus, Noumea, and Eniwetok until 5 Feb 1946; Pearl Harbor 24 Feb 1946; voyage to San Pedro; decommissioned at Pearl Harbor 25 Jun 1946 and 'transferred to the Maritime Commission the next day.'

The 'transferred to the Maritime Commission the next day' (26 Jun 1946) is a paper-transfer statement; the primary MARAD custody record shows physical NDRF Suisun Bay entry 26 Jun 1947 (see ev-02, ev-06). Contains no asbestos or materials information; supports no asbestos claim.

    Authoritative for government custody milestones, tonnage, and the 1974 disposal chain; card handwriting read directly from scans (partially legible).

    asbestos_application
    Finding
    The U.S. Maritime Commission instruction manual for the EC2-S-C1 plant (the design of this vessel's hull) describes cylinder insulation of magnesia under sheet-iron lagging; insulation products of this era were commonly manufactured with asbestos fiber, and period steam-system gaskets, packing, and insulation felts commonly contained asbestos. Liberty-type hulls were built to emergency USMC specifications during the period when the federal government had reserved asbestos supply for shipbuilding. The Navy's October 1942 AK conversion by Matson Co., San Francisco added naval outfitting (armament, communications, berthing for a ~200-man complement, landing boats) whose insulation scope is undocumented.

    Limitations
    Class/design documentation, not a hull record - the manual names the type, not this vessel, and does not itself state 'asbestos' content. Asbestos presence aboard this hull is era inference, not ship-proven. Does not establish quantity, present-day presence (hull scrapped 1975), individual exposure, or causation. Conversion material scope is an open archival lead, not a finding.

    NavSource Service Ship Photo Archive entry for USS Crater (AK-70) confirms the construction/commissioning chain (laid down 28 Aug 1942 as SS John James Audubon, MCE hull 420, Permanente Metals Corp. Yard #2 Richmond; launched 8 Oct 1942; acquired 22 Oct 1942; commissioned 31 Oct 1942, LCDR Russell Dodd USNR; decommissioned 25 Jun 1946) and adds final disposition detail: sold for scrapping 26 Aug 1974 at Suisun Bay to 'Seangyong Trading Co., Ltd.,' Seoul, South Korea, removed October 1974, scrapping completed 30 Mar 1975; call sign NXTX; awards American Campaign, Asiatic-Pacific Campaign, WWII Victory, Philippines Liberation medals; spec block incl. complement 16 officers/189 enlisted, Joshua Hendy VTE engine and 2 B&W header-type boilers. Shipscribe's BuShips-derived class record (shipscribe.com/usnaux/AK/AK70.html) adds: converted by Matson Co., San Francisco; AK-70 carried non-standard armament 1-5"/50, 1-3"/50, 8-20mm in late 1942 (later +2 20mm; Apr 1945 re-gunned to 1-5"/38, 1-3"/50, 10-20mm - one of only three Navy ships with a 5"/50 gun in WWII); 'Laid up at Pearl Harbor June 1946 for use in Operation Crossroads but not used and towed to San Francisco during 1947 for disposal. To NDRF 1947 as merc. JOHN JAMES AUDUBON. To buyer 7 Oct 74'; class acquisition program (Cominch 3 Oct 42 directive; Auxiliary Vessels Board 10 Oct 42 recommendation for ten SF-area EC2 hulls at ~1 per 10 days). shipbuildinghistory's AK table corroborates: AK-70, John James Audubon, Permanente No. 2, hull 420, EC2-S-C1, delivered as AK 31 Oct 42, scrapped 1975. shipindex.org corroborates the name chain (John James Audubon 1942 -> Crater (U.S.S.) 1942 -> John James Audubon; AK.70; IMO 5173890; 10,852 dwt).

    Limitations
    NavSource, Shipscribe, and shipbuildinghistory are compiled references (Shipscribe/shipbuildinghistory derive from BuShips and Auxiliary Vessels Board records), not government publications - the Operation Crossroads nomination and Matson Co. conversion rest on Shipscribe's ship note alone, though the sale/disposal chain is independently confirmed by MARAD primary cards. NavSource page direct-fetch failed; content captured via search-index extract. The 'not used' half of the Crossroads note is consistent with the Defense Nuclear Agency's official target-vessel reconstruction (84 target ships; AK-70 absent, DOI 10.2172/6354996). No asbestos information in any of these sources; supports no asbestos claim.

    Finding
    Date/figure conflicts resolved or flagged. (a) Stricken date: NavSource prints 'Struck from the Naval Register, 23 June 1946' - impossible as printed, since the ship was still in commission until 25 Jun 1946; Shipscribe's disposition table and secondary compilations give 23 Jun 1947, consistent with MARAD fleet entry 26 Jun 1947. Carried as 1947-06-23 with the NavSource typo flagged. (b) NDRF entry year: DANFS 'transferred to the Maritime Commission the next day' (26 Jun 1946) and NavSource's 1946 WSA-transfer-for-Suisun-layup are paper-transfer statements; the primary MARAD status cards and milestone table record physical Suisun Bay fleet entry 6-26-47 1PM PST, and Shipscribe documents the intervening year (Pearl Harbor layup for prospective Operation Crossroads use, then 1947 tow to San Francisco). (c) Decommission date: DANFS/NavSource 25 Jun 1946 vs Shipscribe disposition table 24 Jun 1946 - DANFS carried, conflict noted. (d) Complement: DANFS 198 vs NavSource 16 officers + 189 enlisted (205) vs Shipscribe 133 (1944) and class range 133-207 - DANFS carried. (e) Armament: DANFS abbreviated spec '1x5", 1x3"' vs documented non-standard fit 1-5"/50, 1-3"/50, 8-20mm (later 1-5"/38, 1-3"/50, 10-20mm) - the DANFS block is an abbreviation, not a contradiction.

    No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming USS Crater, SS John James Audubon, or AK-70 was found in the public sources searched (see search_ledger). Live CourtListener API v4 was rate-limited during research (HTTP 429 - shared authenticated 2,800/day quota exhausted, ~9,400 s retry-after; not retried to avoid a ban); Google-indexed CourtListener content for the ship's names and hull number shows only unrelated collisions (JJ Audubon, LLC v. Unknown, 1:20-cv-00917 - a 2020 marine limitation-of-liability docket for a Hornblower New York entity, not this ship; multi-ship complaint schedules such as the Siegfried/Owens-Illinois filing that list other Navy hulls but not Crater). Marketing pages (asbestos-ships.com, freeasbestostesting.com, duboselawfirm.com) list the ship with boilerplate claims and were excluded as non-authoritative - one asserts 'More than 300 asbestos-containing materials were used in the manufacturing of the USS Crater' and 'Everyone who served on the USS Crater (AK-70) inhaled the asbestos fibers.'

    Absence of a located public record does not prove absence of asbestos aboard - a 1942 emergency-built steamship is era-consistent with asbestos-containing materials. The litigation check is a partial negative: CourtListener's own index was unreachable under rate limit, and only the Google-indexed subset of CL content was swept. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.
