- DANFS establishes the hull's identity chain and service: 'Dumaran (ARG-14) was renamed and reclassified Chourre (ARV-1) 22 February 1944; launched 22 May 1944 by Bethlehem-Fairfield Shipyard, Inc., Baltimore, Md., under a Maritime Commission contract; sponsored by Mrs. E. A. Forde, Jr., and commissioned 7 December 1944, Captain A. H. Bergeson in command.' WWII service: Norfolk 2 Mar 1945, Pearl Harbor 12 Apr, Espiritu Santo 29 Apr, aviation repair unit transferred to Saipan, station supply ship replenishing carriers at San Pedro Bay, Leyte 26 May-17 Jul 1945, Guam stores trip 17 Jul-7 Aug, San Pedro Bay until 24 Oct, then Tokyo Bay occupation duty; sailed Yokosuka 1 Jan 1946 for San Francisco ('arriving 4 May'). Out of commission 28 Nov 1948 at Stockton. Recommissioned 21 Feb 1952; operated out of Japan supplying ships off Korea until 28 Feb 1953; two further Far East tours (17 Aug 1953-11 Apr 1954; 30 Aug 1954-1 Mar 1955); out of commission in reserve 13 Sep 1955. 3 battle stars for Korean War service. Stats: dp 4,023; l 441'6"; b 56'11"; dr 22'; s 12 k; cpl 578; armament 1 5". Namesake Lt. Cmdr. Emile Chourre (1894-1938), killed in plane crash at Scott Field, Ill., 26 Jan 1938.

- Limitations
- Authoritative for government custody milestones and disposal terms. The record's printed 'MA-6237' contract line and milestone table are internally consistent with MCE-2637 elsewhere on the cards - one card's 'MA-6237' appears to be a clerical transposition, not a different contract. Contains no asbestos, materials, or condition-survey information; the parts-removal entry documents machinery removal, not insulation disturbance. Supports no asbestos claim.

- Finding type
- vessel_history
- Finding
- Shipscribe class notes document the conversion decision: the Auxiliary Vessels Board (11 Jun 1943) directed a program of 12 EC2 conversions to internal combustion engine repair ships (ARG 4-15); on 25 Aug 1943 CominCh ordered the last two (ARG 14-15) converted instead to aircraft repair ships equipped to overhaul aircraft engines and perform structural repairs on airframes; reclassified ARV 1-2 in February 1944 and given new names in March; ComAirPac made specific shop-facility and personnel-accommodation recommendations 7 Mar 1944. Ship notes for ARV-1: MCE 2637; 'Ex USS DUMARAN 30 Mar 44, ex ARG-14 22 Feb 44. Delivered 79.9% complete. Converted by Bethlehem Steel, Key Highway, Baltimore, Md.' Navy acquisition 31 May 44; keel 20 Apr 44; launch 22 May 44; commissioned 7 Dec 44. Disposition table: decommissioned 13 Sep 55; strike/disposal 1 Sep 62; MA sale 5 Feb 71. Sister ARV-2 Webster (ex-Masbate ARG-15, MCE 2665) built alongside.

- Limitations
- Private authoritative compilation (Roberts), not a government publication - its per-hull data tracks primary records closely and its 1 Sep 1962 strike/disposal date matches the MARAD-documented permanent title transfer, but individual figures are not separately corroborated. Ship note 'In USN reserve 1946-52 (decommissioned 13 Sep 46...)' conflicts with DANFS decommission 28 Nov 1948 - DANFS controls. Renaming: shipscribe shows reclassification 22 Feb 44 and rename effective 30 Mar 44, which DANFS compresses to 22 Feb 44. No asbestos content.

- Mirrored excerpt, engine-cylinder insulation section
- Finding type
- asbestos_application
- Finding
- The USMC operating manual for the EC2-S-C1 plant - the design this hull was built to - 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.

- Limitations
- Class/design documentation, not a hull record - the manual names the type, not this vessel, and does not itself state 'asbestos' content (magnesia lagging of the era was typically asbestos-fiber-reinforced, but the manual text is silent on fiber). Asbestos presence aboard this hull is era inference, not ship-proven. Does not establish quantity, present-day presence, individual exposure, or causation.

- The Navy/U.S. Public Health Service industrial-health survey of pipe-covering operations (two Navy yards and two Navy contract yards, 1944-45) found amosite 'an important ingredient of pipe covering material used on U.S. Navy vessels,' with much asbestos cloth and asbestos cement in use, and identified asbestosis cases among career pipe coverers - documenting the standard wartime naval-construction insulation regime under which this EC2 hull and its ARV conversion were built and outfitted.

- Finding
- CourtListener opinion sweeps: 'Chourre' returned 2 hits, both name collisions (Chourre v. Internal Revenue Service, W.D. Wash. - taxpayer surname; Phoenix New Times LLC v. Arpaio, Ariz. Ct. App. - surname mention; neither involves any vessel); 'Dumaran' returned count 0 - no opinion mentions the name at all. Docket-type search for 'Chourre' and hull-number queries ('ARV-1', 'ARG-14') could not be completed this session - the fleet-wide pacing budget was repeatedly spent; status logged in search_ledger.

- A name match is not a case; both hits classified name collision on case identity (surname, non-maritime, no vessel reference). Sweep coverage is partial: name sweeps complete ('Chourre' 2 collisions; 'Dumaran' zero results), but the docket-type 'Chourre' search and hull-number queries ('ARV-1', 'ARG-14') were blocked by pacing - absence of a qualifying asbestos litigation hit is established only for the completed opinion sweeps. Does not establish or defeat any claim of exposure or legal eligibility.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, court finding, or docketed asbestos case naming Chourre, Dumaran, ARV-1, or ARG-14 was found in the public sources searched (see search_ledger). The MARAD custody chain is fully documented (1960-1971) and contains no materials or hazmat content; the ship was scrapped in 1971, before the asbestos-era survey/abatement documentation practices that produce such records for surviving hulls.

- Finding type
- historical_record
- Finding
- Source discrepancies resolved or flagged: (a) rename/reclassify - DANFS compresses both to 22 Feb 1944; shipscribe ship note shows reclassified ARV-1 effective 22 Feb 1944 and renamed Chourre effective 30 Mar 1944 (class notes: 'reclassified ARV 1-2 in February 1944 and given new names in March'); the two-step sequence is adopted. (b) Stricken - NavSource and Wikipedia give '1961'; shipscribe's disposition table gives strike/disposal 1 Sep 1962, matching the MARAD-documented permanent title transfer 9-1-62; the MARAD card is controlling for custody and 1 Sep 1962 is carried, with the 1961 figure noted as the non-controlling variant. (c) Battle stars - DANFS states 3 for Korean War service; the NavSource page text states 2 while its campaign table lists two named campaigns; DANFS controls. (d) DANFS 'arriving 4 May' after sailing Yokosuka 1 Jan 1946 - unexplained four-month interval, probable misprint, carried in gaps. (e) Shipscribe ship note 'decommissioned 13 Sep 46' conflicts with DANFS 28 Nov 1948 - DANFS controls.
