[2]DANFS entry 'Flicker' (AMS-9), verbatim transcription on the Haze Gray & Underway DANFS mirror (archived capture 2022-09-10; hazegray.org DNS dead as of 2026-10-04) [nhhc_danfs]

- DANFS 'Flicker' entry, single paragraph; AM-70 entry archived at https://web.archive.org/web/20200120095112/http://www.hazegray.org/danfs/mine/am70.htm
- Finding type
- vessel_history
- Finding
- DANFS records that the second USS Flicker was so named and reclassified from YMS-219 to AMS-9 on 17 February 1947; the entire DANFS entry is a namesake note ('A woodpecker of eastern North America') plus the reclassification date. The first Flicker was AM-70, a different vessel (DANFS AM-70 entry: built 1937 by Bath Iron Works as Delaware, acquired 1940, served off Brazil and Newfoundland, decommissioned 3 January 1945, transferred to Maritime Commission 31 March 1945).

- Limitations
- DANFS carries no construction, service, or material detail for this hull - the entry is a one-line namesake/reclassification record. Live NHHC page for Flicker (AMS-9) returns 404 (standing NHHC link-rot defect); cited via archived hazegray transcription, which is labeled as archived and is a mirror, not NHHC itself. AM-70 disambiguation is included because law-firm asbestos listicles name 'USS Flicker AM-70' - the first hull, not this one.

- NavSource records: laid down 23 October 1942 by 'J. N. Martinac Shipbuilding Co. Tacoma, WA' [sic - J. M. Martinac]; launched 23 January 1943; commissioned USS YMS-219 on 7 July 1943; completed 20 July 1943 and assigned to the Pacific Fleet; named Flicker and reclassified motor minesweeper AMS-9 on 17 February 1947 (with the note that the Naval Vessel Register of 1 January 1949 lists decommissioning and placing in reserve as of February 1947); reclassified coastal minesweeper (old) MSC(O)-9 on 7 February 1955; decommissioned September/October 1953 at Naval Station Astoria, OR; struck from the Naval Register 1 January 1960; sold 1962 to Aleutian Marine Transport Co. of Seattle for use as a barge, renamed Bethel No. 1; sold 1967 to Aleutian King Crab, Inc. of Seattle; out of documentation 1984; fate unknown. Specifications: 270 t., 136 ft, beam 24 ft 6 in, 15 kts, complement 32, one 3"/50 mount, two 20mm, two depth-charge projectors; propulsion two 880-bhp GM 8-268A diesels, Snow & Knobstedt single reduction gear, two shafts. Commanding officers: LT Maurice R. Winfield USNR (7 July 1943), LT P. E. Fertig USNR (1945), LTJG Wick Raymond Harlan Jr. USN (1 November 1950 - 19 July 1951), LTJG Herman Jackson Sanders USN (19 July 1951 - 25 July 1952), LT John Douglas Callaway Jr. USN (from 25 July 1952).

- Limitations
- NavSource is a secondary compilation transcribing official data - highly reliable for designations and milestones but not itself a primary record. It prints the builder as 'J. N. Martinac' while every other source (Shipbuilding History, uboat.net, Tacoma News Tribune, the firm itself) gives 'J. M. Martinac' - see correction row. Its 7 July 1943 commissioning date conflicts with the 20 July 1943 date uboat.net prints as commissioning (NavSource calls 20 July 'completed'); unresolved - see gaps. Contains no asbestos or material information.

The NARA 'Navy Deck Logs Available in the National Archives Catalog' page lists 19 YMS hulls with digitized logs; YMS-219 is not among them, so the logs are held but not digitized.

- Shipbuilding History's YMS table records YMS-219 built by Martinac Shipbuilding, Tacoma WA, 136 ft / 320 t., delivered 20 July 1943, reclassified 1947 as Flicker (AMS-9); the postwar table records AMS-9 (ex-YMS-219) 'Flicker', Martinac SB, 270 t., delivered 20-Jul-43, U.S. Navy, struck 1960. The class page states that in the three-year period spring 1942 - spring 1945, 35 boatyards turned out 561 wooden-hulled minesweepers of essentially the same design, and identifies the YMS-135-445 boats as the single-stack Mk. II variant.

- Finding type
- asbestos_application
- Finding
- A wooden-hulled diesel-driven yard minesweeper built 1942-43 sits inside the Navy's documented asbestos-use era, but aboard this type the asbestos-relevant systems were narrow: with no boilers or steam plant, the boiler/turbine lagging pathway does not apply. Era-standard applications aboard small diesel minesweepers of this period were diesel-engine and exhaust lagging, gaskets and flange packing, electrical insulation, and limited domestic-space insulation.

- GAO reviewed the Navy's efforts to protect workers from asbestos exposure at Long Beach and Norfolk Naval Shipyards, covering the use of asbestos in Navy ships, the cost of removal, and compensation programs; it documents the Navy's 1975 policy of removing/replacing only damaged insulation and the 1979 modification to selectively replace asbestos insulation in high-maintenance areas - i.e., asbestos insulation was standard aboard Navy ships of this era and remained unless disturbed.

- Finding
- The builder's yard is a confirmed state cleanup site under Washington's Model Toxics Control Act (independent cleanup, institutional controls in effect via four 2007 environmental covenants restricting soil disturbance and building removal). The published contaminant list covers metals including arsenic (confirmed in soil and sediment); asbestos does not appear in the listed contaminants.

- Limitations
- Yard-level environmental record, not a hull record - it documents land/sediment contamination at the Tacoma site decades after this vessel's 1943 construction and does not bear on materials installed aboard YMS-219. Absence of asbestos from the published contaminant list does not establish absence of asbestos use at the yard during WWII.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS YMS-219 / USS Flicker (AMS-9 / MSC(O)-9) was found in the public sources searched (see search_ledger). CourtListener: 'YMS-219' opinion and docket searches each returned count 0; 'Flicker' opinion search returned 977 hits, all surname-Flicker party cases on the sampled page - name collision, not a vessel hit; the authorized 'Flicker'+asbestos variant returned 15 hits, all counsel/surname collisions - no qualifying asbestos opinion names this vessel; the 'Flicker' docket query could not be completed - fleet-wide request budget repeatedly spent; logged as blocked in the search_ledger, not as a negative result. Law-firm marketing listicles carry 'USS Flicker' minesweeper entries (mesothelioma.com, mesotheliomahelp.org) but are excluded by source policy, and the mesothelioma.com entry identifies AM-70 - the first, different Flicker.

Deck logs (NARA RG 24, SL44 p. 116) and any Martinac builder records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.

- Commissioning-date conflict: NavSource prints 'Commissioned USS YMS-219, 7 July 1943 / Completed 20 July 1943', while uboat.net prints 'Commissioned 20 Jul 1943' and Shipbuilding History prints 20-Jul-43 as the delivery date - 7 July (NavSource) is carried as commissioning and 20 July as completion/delivery, but the conflict is unresolved. Builder-name conflict: NavSource prints 'J. N. Martinac Shipbuilding Co.'; the firm's name is J. M. Martinac Shipbuilding Corp. per Shipbuilding History, uboat.net, and the Tacoma News Tribune. Wikipedia's infobox prints 'Commissioned 17 February 1947' - the AMS-9 rename/reclassification date, not a commissioning. Tonnage conflict: NavSource spec block 270 t. vs Shipbuilding History table 320 t. (displacement convention).
