Entry notes an earlier Impervious (AM-245), an Admirable-class minesweeper under construction by Tampa Shipbuilding Co., canceled 6 June 1944 - a different hull. AM-449 launched by Martinolich Shipbuilding Co., San Diego, Calif., 29 August 1952; sponsored by Miss Mary Lin Moore; commissioned 15 July 1954, Lt. Comdr. A. T. Ford in command. After shakedown and mine warfare training off California, reclassified MSO-449 on 7 February 1955; sailed 1 July 1955 for 7th Fleet duty, arriving Sasebo via Pearl Harbor 5 August; operated with Republic of Korea Navy ships and visited Taiwan; home port Long Beach, returned 15 February 1956. Second 7th Fleet deployment from 3 January 1958, six months in Japanese waters; trained Nationalist Chinese crews April-May; returned Long Beach 15 July 1958; September amphibious exercise off Camp Pendleton. April 1959 joint mine warfare exercise with Canadian ships; 1960 deployment sailed 3 May for Japan, maneuvers with Korean and Nationalist Chinese ships in August, operations with Philippine Navy off Corregidor in October, return to Long Beach 16 November via Guam and Pearl Harbor. 7th Fleet duty again from 7 April 1962: part of July on patrol with Vietnamese Naval units off Danang; Hong Kong and Yokosuka visits; Pearl Harbor 8 September; October-November atomic tests at Johnston Island; Long Beach 21 November. March 1963 amphibious operation 'Steelgate'; November mine warfare exercises with Canadian ships off British Columbia. WestPac again 8 May 1964; September on the coast of South Vietnam for special operations supporting the American Advisory unit; mine exercises off the Philippines; returned Long Beach 7 December 1964; the following 12 months SoCal exercises, overhaul at Los Angeles, and readiness operations.

- Finding type
- litigation_documented
- Finding
- Adopted federal report and recommendation in a docketed asbestos personal-injury action expressly names this hull and recites deposition-record duties aboard: Gerald L. Hickman (Navy 1963-1986, engineman rating) was 'stationed on the USS Impervious, a minesweeper, in Long Beach, California' in 1965, became fireman second class aboard, 'engaged in a more supervisory role, but still assisted in repairing diesel engines, pumps, valves, boilers, and air conditioning equipment,' and after two years aboard transferred to USS Endurance for similar duties. The action alleged asbestosis and asbestos-related pleural disease from career asbestos exposure; the R&R recommended granting defendant Air & Liquid Systems Corp. summary judgment because Hickman could not place the defendant's Buffalo pumps aboard any specific ship and his unsworn declaration was disregarded as sham - adopted 19 August 2019. The exposure record as to this defendant resolved adversely to plaintiff at summary judgment; claims against other defendants are not adjudicated in the located documents.

- Litigation-stage discipline: ship-name and duty recitals are discovery-stage record facts (deposition excerpts quoted in an adopted R&R); the only adjudicated outcome located is a defense summary-judgment win on product-identification/causation grounds - a merits-level negative for that plaintiff as to Air & Liquid, not an affirmative finding that asbestos exposure occurred aboard this hull. No asbestos-containing product was attributed to Impervious in the located record; the 'boilers' in the recital is the court's summary of testimony on a diesel-powered hull (auxiliary equipment or loose usage unresolved). Disposition of claims against other defendants (CBS Corp. et al.) not located; CourtListener API quota-blocked this session so the PACER-level sweep is incomplete. Does not establish or defeat any individual claim of exposure or legal eligibility.

- Finding
- Docketed federal asbestos complaint naming this hull with product-level allegations: plaintiffs Eusebio V. Jacob and Marta A. Jacob allege that Jacob, a journeyman electrician at the Navy Ship Repair Facility, Guam, c.1962-1985, was 'repeatedly exposed to great quantities of asbestos, asbestos dust and fibers when he installed asbestos gaskets in their respective equipment on the USS Asheville, USS Banner, USS Brister, USS Engage, USS Fortify, USS Grasp, USS Haverfield, USS Impervious, USS Inflict and USS Ponchatoula' (vessel list per Guam Daily Post's report of the complaint). Alleged products per the reporting: PLENCO asbestos-containing thermostat plastic molding materials and Rockwell controllers, circuit breakers, switches and other electrical equipment containing asbestos parts, supplied to the U.S. Navy and the Guam Navy Ship Repair Facility. Jacob was diagnosed with malignant mesothelioma in August 2018. Docket shows complaint filed 20 June 2019 (Filing 1, with Exhibit A and jury demand); summonses executed July 2019; the Justia mirror was last retrieved 6 August 2019.

- PLEADING-STAGE ALLEGATION, never an adjudicated finding: a complaint's vessel list and product allegations are assertions, not exposure findings - nothing about this hull was proven, and no discovery record, trial finding, or judgment naming this hull was located. The complaint text itself was not retrieved (PACER not queried; CourtListener API quota-blocked); the vessel list rests on the docket record plus Guam Daily Post reporting quoting the complaint, corroborated by Pacific Daily News. The exposure theory is yard-side gasket installation aboard the vessel at Guam SRF - not service aboard as crew - and does not speak to originally installed materials. Later disposition unlocated (docket mirror ends August 2019); carried in gaps.

[6]N.R. Acquisition Corp. v. United States, 52 Fed. Cl. 490 (2002) (No. 97-338 C, Bush, J., May 14, 2002) - opinion and order denying defendant's summary-judgment motion on the special plea in fraud and plaintiff's cross-motion [court_record]
- Locator
- 52 Fed. Cl. 490, 491-496 (factual background; IFB asbestos notice; Ellis/Seawitch indictment and convictions)
- Finding type
- litigation_documented
- Finding
- The prime contractor that bought this hull for scrap in 1994 (NRA Acquisition Corp. of New York, per NavSource) litigated its DRMS naval-vessel scrapping contracts to a published Court of Federal Claims opinion. The opinion addresses the USS Coral Sea contract and recites the disposal program's asbestos framework: the invitation for bids informed bidders the vessel 'might contain asbestos,' NRAC claimed the government 'had extensive information regarding the presence of asbestos materials aboard' the ship but failed to disclose it, and subcontractor Seawitch Salvage and owner Kerry L. Ellis, Sr. were convicted of Clean Air Act asbestos-removal violations and false statements that licensed contractors had performed the asbestos removal - convictions affirmed by the Fourth Circuit (172 F.3d 864, Table, 1999). The court denied the government's special-plea-in-fraud summary-judgment motion, holding the subcontractor's criminal convictions were not imputed to the prime contractor on the record presented.

- Finding
- Contemporaneous local-press documentation of the disposal-yard failure in this hull's documented scrapping chain: Sigma Recycling (successor name of Wilmington Resources, Inc., the subcontractor to which Impervious was consigned per NavSource) dismantled old Navy ships at a 26-acre site off U.S. 421 on the Northeast Cape Fear River near Wilmington from 1994 to 1996; workers 'stripped fire-retardant asbestos from walls,' and the site was left contaminated with petroleum, lead, and asbestos. More than a dozen environmental and worker-safety violations forced shutdown; a 1996 state raid identified the pollution extent; the federal government fined the company $232,400 for asbestos-standards violations; ten vessels were returned to Baltimore; a ~$1 million state-supervised cleanup (560 tons of lead/asbestos soil removed, 17 biopiles) was nearing approval in 2001.

[10]Era/design inference anchored to NVR physical-characteristics fields for this hull (wood hull; diesel propulsion) and standard references for the MSO-422 design [other_primary]

- Finding type
- asbestos_application
- Finding
- Era/design inference only: Impervious is a wooden-hulled, non-magnetic, diesel-propelled ocean minesweeper (NVR hull material and propulsion fields), so the boiler-room/steam-line lagging envelope that dominates steam-combatant asbestos profiles does not apply. Asbestos use aboard a 1951-52-built Navy hull of this type, if present, would concentrate in ancillary materials: machinery gaskets and packing, engine exhaust/muffler lagging, electrical cable and component insulation, interior joiner and fireproofing materials, deck covering, and winch/windlass brake linings. The litigation records for this hull are consistent with ancillary pathways (gasket installation in electrical equipment per the Jacob complaint; engine/pump/valve repair duties per the Hickman deposition recital).

- Absence of a located adjudicated record does not prove absence of asbestos aboard - the ship was built inside the Navy's asbestos era and served 37 years; equally, the litigation allegations do not prove presence. The hull was scrapped in the United States by 2000-2002, so no present-day survey pathway exists. The litigation negative is provisional because the docket-level CourtListener sweep could not be executed this pass and the Hickman docket was not fully retrieved (other defendants' dispositions unlocated).
