- DANFS documents for this hull: 'Lodestone was laid down as PCB-876 [sic - PCE-876 per all other sources] by Albina Engine & Machine Works, Portland, Oreg., 27 May 1943; launched 30 September 1943; sponsored by Miss Virginia Phillips; renamed YDG-8 23 December 1943; and commissioned 10 June 1944, Lt. Comdr. C. V. Schlaet in command.' Spec block: dp. 640 (lt.); l. 184'6"; b. 33'; dr. 9'; s. 14 k.; cpl. 65; a. 1 3", 4 20mm.; cl. YDG-8. Service: after shakedown YDG-8 departed San Pedro 18 August (1944) for the South Pacific; operated out of Tulagi until early October, then joined the 7th Fleet, arriving Manus, Admiralty Islands, 6 October; for the rest of the war provided degaussing services in the Pacific Islands, primarily at Manus and in the Philippines. Postwar: returned to the United States, decommissioned May 1946, joined the Reserve Fleet berthed at San Diego; reclassified ADG-8 1 November 1947; named Lodestone 1 February 1955.

The DANFS entry was written while the ship was still in the reserve fleet ('at present is berthed at San Diego') and predates the 1975 striking and 1976 scrapping - final-disposal facts come from other rows. 'PCB-876' is a printed error for PCE-876 (see correction row).

- NavSource timeline for this hull: laid down 27 May 1943 as PCE-876 by Albina Engine and Machine Works, Portland, OR; launched 30 September 1943; reclassified District Degaussing Vessel YDG-8 23 December 1943; commissioned USS YDG-8 10 June 1944; decommissioned May 1946; reclassified Degaussing Ship ADG-8 1 November 1947; named Lodestone 1 February 1955; struck from the Navy Register 21 February 1975; 'Sold for scrap to the National Steel and Shipbuilding Co., Treasure Island, CA for $44,500'; scrapped 1 May 1976. Specifications: displacement 640 t.; length 184'6"; beam 33'; draft 9'; speed 14 kts.; complement 65; armament one 3"/50 dual purpose mount and four 20mm mounts; propulsion two 900 bhp General Motors 12-567A diesel engines, Falk single reduction gear, two shafts. Call sign NJYX. Commanding-officer table lists six USNR COs beginning LCDR Carl Vincent Schlaet (dated 10 July 1944). Photo captions identify NARA/NHHC images 19-N-69085 (builder photo, 14 June 1944), 19-N-69080 and 19-N-69082 (builder photos, 21 June 1944), and NH 77377 (probably San Francisco Bay, soon after return to the West Coast February 1946).

- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - its dates generally track DANFS/NVR but the page carries internal inconsistencies: a second 'Decommissioned in November 1947' entry after the May 1946 entry (the hull was already in reserve; see correction row), and a commanding-officer date (10 July 1944) that conflicts with the page's own 10 June 1944 commissioning line. The buyer name/location 'National Steel and Shipbuilding Co., Treasure Island, CA' conflicts with the known identity of that firm (see gaps). Contains no asbestos content; the 1976 breakup predates modern ACM-handling regulation and no hazmat record for it was located.

- Shipscribe's Navy-record compilation gives, for LODESTONE (ADG-8): reclassified 23 Dec 43; builder Albina Engine & Machine; keel 24 Mar 43; launch 16 Jul 43; commissioned 10 Jun 44; decommissioned 16 Oct 46; struck 21 Feb 75; disposal 13 Apr 76, fate Sold. Ship notes detail the inactivation: ex-PCE-876 23 Dec 43; returned to the West Coast Feb 46; to San Pedro 3 Jun 46 and reported for inactivation; decommissioned 16 Oct 46 'in interest of inactivation program,' inactivation 93% complete; towed from San Pedro to San Diego by ATR-87 23 Oct 46; placed in inactive status 30 Dec 46 'Out of Commission, In Reserve,' inactivation complete; in USN reserve 1946-75; reclassified ADG-8 from YDG-8 1 Nov 47; name assigned 1 Feb 55, previously unnamed; delivered to buyer 26 Apr 76 for scrapping. Class notes: YDGs 8-10 were FY1942 ships built on the Navy 180-ft PCE/AM design (640 light / 903 lim tons; 184.5' oa; 15.7 kts; 2,000 HP diesel, 2 screws; class-design complement 99); YDGs - 'Mobile Degaussing Units' - provided degaussing (deperming) services where shore facilities were not available; on 19 Sep 47 CNO ordered YDG 8-11 reclassified AGD 1-4, BuShips countered with ADG 8-11, and SecNav approved the modified reclassification 13 Oct 47.

- Limitations
- Shipscribe is a researcher compilation from Navy records, not itself a primary document - but it is unusually detailed and internally sourced. Its keel/launch dates for Lodestone (24 Mar 43 / 16 Jul 43) conflict with DANFS and NavSource (27 May 43 / 30 Sep 43), which Shipscribe assigns to Magnet (ADG-9) - unresolved, see correction row and gaps. The 99-man complement is a PCE-type class-design figure, not this hull's muster. No asbestos content.

- Finding type
- historical_record
- Finding
- Four documented conflicts, resolved as stated: (1) Commissioning - DANFS, the NavSource timeline, and shipscribe all give 10 June 1944; a 10 July 1944 variant circulates (Wikipedia infobox; NavSource's own CO table dates LCDR Schlaet from 10 July 1944) - 10 June carried. (2) Keel/launch - DANFS, NavSource, and Wikipedia give Lodestone 27 May 1943 / 30 September 1943; shipscribe assigns those identical dates to Magnet (ADG-9) and gives Lodestone 24 March 1943 / 16 July 1943. NavSource prints the same 27 May / 30 Sep dates on BOTH Lodestone's and Magnet's pages - impossible for two distinct hulls, so at least one NavSource page carries a copy error; DANFS dates carried for this hull, conflict unresolved. (3) Decommissioning - DANFS says May 1946; shipscribe's inactivation chronology gives decommissioned 16 October 1946 with 'Out of Commission, In Reserve' status 30 December 1946; NavSource prints both 'May 1946' and a duplicate 'Decommissioned in November 1947' line (also present on its Magnet page - a template/copy artifact, not a third event). (4) Identity - DANFS prints 'laid down as PCB-876,' sic for PCE-876; the hull was reclassified to YDG-8 before commissioning and never served as a patrol craft escort.

[9]Era inference built on: DANFS spec block and construction dates (1943-44 Albina-built auxiliary); NavSource specifications (2 x GM 12-567A diesels, 2 shafts); shipscribe class design data (Navy 180' PCE/AM design); Corn & Starr AJIM 1987 (WWII shipbuilding asbestos era - see ev-06) [other_primary]

- Finding type
- asbestos_application
- Finding
- A steel auxiliary built 1943-44 at a Portland, OR commercial yard sits inside the documented WWII-era window of extensive asbestos use in U.S. shipbuilding. Era-standard applications for a vessel of this type and period were thermal insulation, machinery and diesel-exhaust lagging, gaskets, valve packing, and electrical insulation; aboard a degaussing vessel the high-current deperming cable and equipment plant adds era-typical electrical-insulation context. She was diesel-propelled with no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply to this hull.

- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII, and that wartime demand drove unprecedented asbestos utilization aboard naval and merchant construction - the era and program under which this 1943-44 hull was built and converted to a degaussing vessel before commissioning.

- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's construction (1943-44), commissioned service (1944-46), and nearly all of her reserve-fleet retention (1946-75).

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or litigation naming USS Lodestone (YDG-8/ADG-8, ex-PCE-876) was found in the public sources searched. CourtListener: all 4 base queries run (opinion + docket for 'Lodestone' and 'ADG-8'); retrieved hits were name collisions only (legal metaphor, corporate/property names, document IDs), and the asbestos-qualified variant 'Lodestone asbestos' returned 0 opinions. Secondary web sweeps surfaced only law-firm marketing content (freeasbestostesting.com and similar listicles) listing the hull as asbestos-bearing without primary sourcing - excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943-44 hull is era-consistent with asbestos-containing construction. CourtListener base queries overflowed their 20-result pages on a high-collision name; only first pages were classified, but the asbestos-qualified variant covered the substantive question (0 hits). PACER-state searches, deck logs, BuShips outfitting/work records, and scrapping-contract records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
