- The hull was acquired by the Navy 28 June 1955 and 'converted to Navy use at Charleston Naval Shipyard,' commissioning there 15 February 1956 (LCDR Boyd L. Hall). NavSource confirms: 'Converted to a Radar Picket Ship at Charleston Naval Shipyard, Charleston, S.C.' This 1955-56 naval-shipyard conversion is the hull's principal documented industrial yard period - deep interior rework for radar suites, combat information center, and expanded crew accommodations.

- Finding
- The USMC operating manual for the EC2-type plant 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. This hull is the Z-EC2-S-C5 variant - a hull-form variant (boxed aircraft transport) of the EC2 design carrying the same standard machinery specification; NavSource's posted specs for AGR-8 confirm the Liberty-type plant in converted service (two 220-psi boilers, one 3-cylinder triple-expansion reciprocating engine, 2,500 shp, one 4-blade 18'6" propeller). Liberty ships were built during the period when the federal government had reserved asbestos supply for shipbuilding.

The federal action (S.D.N.Y.) was dismissed on the merits 12 November 1952; the Second Circuit appeal was not perfected and was dismissed; the subsequent New York state suit was held barred - the federal dismissal controls, and a state court may not sit as an appellate court reviewing the federal action.

Its record value: it documents Moore-McCormack Lines as an operating agent of this hull in 1948 (consistent with DANFS 'served several lines') and establishes that crew litigation aboard this hull exists in the reported record. Citation verified via the official reporter citation (286 A.D. 462, 144 N.Y.S.2d 682) as quoted in Wilkins v. American Export Isbrandtsen Lines, 46 A.D.2d 244 (1974); CourtListener was unreachable at research time (API rate limit + HTTP 403) and OpenJurist returned 403 to automated fetch, so the opinion text was not re-pulled this pass - stage is pleadings/dismissal as described by the Appellate Division.

- Finding
- Second Circuit ruling addressing mesothelioma claims by a mariner aboard War Shipping Administration vessels; the court considered jurisdiction over a personal-injury claim against the United States for asbestos exposure aboard the WWII government merchant fleet. Claims against the government were barred on discretionary-function grounds - the characteristic litigation posture for merchant-era exposure aboard Liberty-type hulls. This hull was delivered to and operated under the War Shipping Administration from 8 November 1945.

- Fleet-level jurisdictional ruling; does not name this hull, does not find asbestos conditions aboard any specific vessel, and establishes only the litigation posture for WWII merchant-fleet claims. Temporal caveat: WSA was abolished effective 1 September 1946 while this hull remained in merchant service to June 1948, so only part of its merchant career ran under WSA itself (post-abolition operation continued under Maritime Commission agency agreements). Reporter citation confirmed: 891 F.2d 31.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1945 hull converted at a naval shipyard in 1955-56 is era-consistent with asbestos-containing materials. Does not establish that asbestos was or was not present; does not establish or defeat any claim of exposure or legal eligibility. CourtListener blockage means opinion/docket-level coverage is unverified rather than confirmed-empty - flagged honestly rather than claimed as no result.

- This hull carried the standard Liberty-type steam plant - two 220-psi boilers and a 3-cylinder triple-expansion engine of 2,500 shp, the machinery family for which the USMC operating manual describes magnesia cylinder insulation 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. Her 1955-56 radar-picket conversion at Charleston Naval Shipyard falls inside that yard's documented asbestos-products era (magnesia pipe insulation; pipe insulation containing 5-50% asbestos; boiler external coatings at 15% asbestos; spray-on insulation for walls and ship interiors; asbestos gaskets; packing; electrical insulation). Era-standard applications aboard a converted steam auxiliary of this type and period: boiler and steam-drum insulation; steam-line lagging; valve and flange gaskets; machinery packing; spray-applied fireproofing and insulation in reworked compartments; electrical insulation; brake linings on winches and windlass.

- Limitations
- Class/era and yard-level inference only - no hull-specific insulation survey, material list, or conversion work package located for YAGR-8/AGR-8. The USMC manual names the EC2-S-C1 type (this hull is the Z-EC2-S-C5 variant sharing the same machinery specification); the manual does not itself state 'asbestos' content. Charleston yard documentation is yard-level, not hull-level. Names era-standard applications, not confirmed installed materials. No quantity.

- Finding
- The yard that converted this hull in 1955-56 has yard-level asbestos documentation: OSHA's 1988 health-complaint inspection at Charleston Naval Shipyard produced an asbestos-standard citation (Inspection 100361849, Commander Charleston Naval Shipyard Code 106; one 'Other' citation under 29 CFR 1910.1001 D07 I; case closed 2 May 1990), and the Atlas yard dataset documents an era product list spanning magnesia pipe insulation, mid-percent-asbestos pipe insulation and boiler coatings, spray-on ship-interior insulation, gaskets, packing, and electrical insulation - plus later yard-level litigation (Whalen 2014; Twidwell 2018).

- Yard-level documentation, not a hull record - the OSHA inspection is 1988, three decades after this conversion, and names the yard establishment, not YAGR-8; the yard product list is era documentation, not a work package for this hull. The OSHA inspection-detail page could not be fetched live this session (osha.gov blocks automated fetch) - the inspection number and citation content rest on the Atlas yard dataset. Does not establish materials aboard this hull, individual exposure, or quantity.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, or hazmat disclosure naming USS Interceptor (YAGR-8/AGR-8) or SS Edward W. Burton was found in the public sources searched. One pleading-stage litigation hit naming the vessel was located in the CourtListener docket index (see ev-uss-interceptor-yagr8-09). The only 'asbestos aboard' material located is law-firm/marketing ship-list content asserting asbestos exposure without primary sourcing - excluded by source policy. NVR check: AGR-8 has no entry - the Naval Vessel Register excludes ships disposed prior to 1987 (hull disposed 1978). NARA digitized deck-log index lists Guardian-class siblings (AGR/YAGR-1, -2, -3, -4, -5, -6, -12, -16) but not AGR-8 - the 1956-65 deck logs are an open archival lead, not digitized as of this session.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1945 steam-hull Liberty variant rebuilt at a documented-asbestos-era yard in 1955-56 is era-consistent with installed asbestos-containing materials, and 1978 shipbreaking predates modern ACM-handling documentation. CourtListener hull-number queries were fleet-paced at commit time - see search_ledger; the two completed base queries returned one pleading-stage hit (ev-09) and one empty result. Undigitized deck logs, conversion work packages at Charleston NSY, and scrapping-contract records under PD-X-1025 remain open leads. Does not establish or defeat any claim of exposure or legal eligibility.

- Finding
- Pleading-stage litigation hit naming this vessel. CourtListener RECAP docket search on 'USS Interceptor' returned one document: a NOTICE OF POTENTIAL TAG-ALONG filed 2011-08-09 on the JPML master docket In re: Asbestos Products Liability Litigation (No. VI), MDL No. 875 (Judge Eduardo C. Robreno), attaching the complaint in Caldwell vs A.W. Chesterton Company et al., W.D.N.C. Asheville No. 1:11-cv-00182 (filed 2011-07-26) - a 30-page asbestos products-liability complaint whose indexed text contains 'USS Interceptor.' Per Peter G. Angelos PC counsel on the JPML docket. This is a complaint allegation - the vessel is named in a pleading within the asbestos MDL; the allegation is unadjudicated and the pleading text itself is not retrievable (CourtListener storage returns NoSuchKey for the document file; the HTML interface blocks automated fetch).

- Finding type
- historical_record
- Finding
- CORRECTIONS on secondary-source details: (1) Layup fleet location - NavSource says 'Wilmington, DE' but the MARAD reserve-fleet vessel-data card reads 'Wilm. NC' (the NDRF Wilmington fleet was the Cape Fear River, N.C. site); DANFS says only 'Wilmington'. MARAD card carried. (2) Merchant operators - NavSource/DANFS name only T.J. Stevenson & Co.; the MARAD status card documents the full WSA allocation sequence (T.J. Stevenson GAA 11-8-45; Cosmopolitan Shipping MC/BB 9-24-46 then GAA 1-4-47; Moore McCormack GAA 1-25-47 then MC/BB 2-28-47; A.L. Burbank & Co. GAA Philadelphia 6-2-48). Wikipedia's infobox operator 'R.A. Nichol & Co. Inc.' does not appear on the status card and is uncorroborated. (3) Completion date - MARAD AGR-8 card says 'DATE BUILT 9-28-45' while the BURTON status card says 'Completed 11-8-45' and 'Basis to W.S.A. 11-8-45'; Wikipedia prints 'Completed 28 September 1945'. Both MARAD milestones are recorded; WSA delivery 11-8-45 carried as the delivery date. (4) Disposal dates - NavSource 'scrapped, 16 February 1978' is the sale/delivery date to American Ship Dismantlers under PD-X-1025 (2-16-78); the MARAD fleet withdrawal milestone is 3-18-78. Both carried distinctly, not merged.
