- Finding
- DANFS record for this hull: fourth Grosbeak; launched as YMS-317 by the South Coast Co., Newport Beach, Calif., 27 February 1943 (sponsor Mrs. Marjorie Boutelle); commissioned 18 November 1943, Lt. John B. Warner in command. After shakedown, swept the San Francisco Bay area until 3 May 1944, then Pearl Harbor; in the Pacific acted as escort to convoys in back and staging areas (Eniwetok, Saipan, Kwajalein) plus patrolling and minesweeping. Post-war: Pearl Harbor overhaul, then Charleston S.C. via San Pedro and the Panama Canal June 1946 with another overhaul; named Grosbeak and redesignated AMS-14 18 February 1947. Post-war career as training ship at the Mine Warfare School, Yorktown, Va., and the Naval Minecraft Base, Charleston; experiments at the Naval Mine Countermeasures Station, Panama City, Fla.; exercises New England to the Gulf of Mexico; Operation PORTEX in the Caribbean out of Vieques Island 24 February - 19 March 1950; first of her type Yorktown-to-Charleston via the Intracoastal Waterway February 1951; Battle Efficiency 'E' 1950, 1951, and 1952; periodic overhauls at Charleston; visits to Miami and New York. Sailed to Green Cove Springs, Fla., 16 November 1955; decommissioned there 7 December 1955; hulk approved for disposal 27 October 1959; struck from the Navy List 1 November 1959. Spec block: YMS-317 - dp. 270; l. 136'; b. 25'; dr. 8'; s. 15 k.; cpl. 32.

- Limitations
- DANFS documents identity, construction, service, and disposal chain - not materials or asbestos content. The documented Pearl Harbor (1945-46) and Charleston (1946 onward) overhauls are exposure-relevant events but no asbestos or material scope is recorded. DANFS omits the laid-down date and any 1947 decommissioning (NavSource supplies both - see gaps). Live NHHC URL serves 404; Wayback capture of the canonical NHHC page cited.

- Finding
- NavSource record for this hull adds milestones and details DANFS omits: laid down 30 October 1942 as YMS-317; 'Decommissioned 2 January 1947' during the Charleston overhaul period, then named Grosbeak and reclassified AMS-14 on 18 February 1947 (no recommissioning date listed); reclassified Coastal Minesweeper (Old) MSC(O)-14 on 7 February 1955; struck from the Navy Register 1 November 1959. Post-Navy: 'Acquired in 1961 by Marine Acoustical Services, Inc. of Miami, FL for use as a research vessel and renamed Paul Langevin. Marine Acoustical was under contract with the Military Sealift Command to conduct underwater sound research in the Labrador Basin for the Naval Underwater Systems Center, Newport, RI. Out of documentation in 1963. Fate unknown.' Propulsion: two 880 bhp General Motors 8-268A diesel engines, Snow and Knobstedt single reduction gear, two shafts. Armament: one 3"/50 dual-purpose mount, two 20 mm mounts, two depth-charge projectors. Commanding officers: LT John B. Warner USNR (1943); LT G. A. Cope Jr. USNR (1945); LTJG Wyatt Eugene Harper Jr. USN (1950-June 1952); LTJG James Lloyd Moss USN (June 1952-May 1953); LT Cyril J. Hartman Jr. USNR (May 1953).

- Limitations
- NavSource is a contributed secondary archive, not a government record - used for the laid-down date, propulsion/armament spec, CO roster, and post-Navy career where DANFS is silent. Its 2 January 1947 decommissioning conflicts with DANFS's continuous-service narrative (recommissioning undocumented - carried in gaps). Beam 24'6" vs DANFS 25' - carried in gaps. The Paul Langevin phase is corroborated by shipscribe's documentation of the same operator's later RV Paul Langevin II but no federal documentation (MSC contract file, USCG documentation record) was retrieved.

- Proceedings 74/1 (Jan 1948), p.539 - power-plant and internal-arrangement passages
- Finding type
- asbestos_application
- Finding
- YMS-class machinery fit documented by a serving officer: wooden hull; two General Motors diesels for main propulsion (electro-pneumatically controlled); a similar diesel direct-connected to a generator for magnetic minesweeping; auxiliary diesel generators for ship's power. No boilers and no steam distribution - the plant type that carried the era's dominant asbestos application (thermal insulation of boilers and steam piping) is absent from this class.

- Population
- YMS-class crews (~32 per boat); construction trades at ~35 yacht yards
- Limitations
- Class/era inference, not a hull record: describes sister ship YMS-238 and the type generally; never mentions asbestos. The conclusion that this hull lacked steam-plant insulation is structural inference from the documented plant; does not establish presence or absence of residual ACM (gaskets, clutch facings, cable insulation) aboard YMS-317/Grosbeak.

- Finding type
- asbestos_application
- Finding
- The Navy told GAO that 'all ships contain some asbestos in such components as clutches and electric cables,' while thermal insulation was the Navy's major shipboard use of asbestos; the Navy's enclosure adds that shipboard piping-system gaskets and packing contained asbestos, that asbestos appeared in equipment brakes and clutches, and that it was 'nearly impossible to build a Navy ship free of the mineral.' For a diesel-powered wooden minesweeper the residual documented applications - clutch facings, electric-cable insulation, engine gaskets and packing - are the relevant era-typical categories.

- Finding
- Post-Navy phase corroboration: NavSource records this hull acquired in 1961 by Marine Acoustical Services, Inc., of Miami and renamed Paul Langevin for underwater sound research under Military Sealift Command contract in the Labrador Basin for the Naval Underwater Systems Center, Newport, R.I.; out of documentation 1963. Shipscribe's YAG-62 notes independently document the same Miami company operating a later RV Paul Langevin II (ex-Deer Island, acquired 1970), consistent with NavSource's account of this hull as the earlier Paul Langevin.

- Finding type
- vessel_history
- Finding
- DANFS documents this hull undergoing a 'badly-needed' overhaul at Pearl Harbor after the war's end (1945-46), a further overhaul on arrival at Charleston in June 1946, and 'periodic overhauls at Charleston' through 1955 while based at the Naval Minecraft Base - roughly a decade co-located with Charleston Naval Shipyard. Both Pearl Harbor Naval Shipyard and Charleston Naval Shipyard are Atlas-dataset yards with documented asbestos use; overhaul and availability events are the classic maintenance-disturbance pathway for era materials.

- Limitations
- The overhaul and homeport events are ship-specific (DANFS); the asbestos dimension is entirely contextual - no work order, availability record, or material list ties any asbestos product to this hull, and DANFS does not name the performing facility for the Pearl Harbor work. Yard-level documentation establishes conditions at the yards, not aboard this vessel; this row exists to cross-link documented events with documented asbestos yards and supports no shipboard finding.

- No qualifying ship-specific asbestos record located: no litigation naming YMS-317 / AMS-14 / MSC(O)-14 / USS Grosbeak (this hull) / Paul Langevin in CourtListener opinion results (six 'Grosbeak' opinion hits are all name collisions - bird references and 'Grosbeck' surnames); no asbestos survey, abatement contract, or hazmat disclosure found for this hull in the public sources searched (see search_ledger). CourtListener docket-index (type=r) sweeps and the bare 'AMS-14' opinion query remained pending at record close - the fleet-wide pacing budget was exhausted this session; disclosed in the ledger and gaps.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era materials in a 1943 diesel minesweeper would still be consistent with class inference. The pending docket sweep is disclosed: undocketed or unindexed litigation naming this hull could exist. Does not establish or defeat any claim of exposure or legal eligibility. Same-name collision risk documented: Grosbeak 1865 / SP-566 / AMc-19 are different hulls; 'Grosbeak' also collides with bird references and the surname Grosbeck.

- Archival leads where a hull-level material record would live: this hull's deck logs for its entire commissioned service (1943-1955 as YMS-317, then AMS-14/MSC(O)-14) fall within NARA's deck-log series 594258 - the primary source most likely to document yard availabilities, maintenance disturbances, and any material events aboard; Charleston Naval Shipyard work-order records for the documented 1946-1955 overhauls; the MARAD disposal file for the 1959 disposition approval; and the MSC/Marine Acoustical Services contract file for the 1961-63 Paul Langevin conversion and research service (conversion scope unknown - could include insulation work).

Whether this hull's logs are digitized was not confirmed (NARA catalog API returned no response to automated query on 2026-09-23); logs are chronological event records and would not themselves identify asbestos content.
