- DANFS record for this hull, verbatim: 'Creddock - A shore bird better known as turnstone. AM-356: dp. 530 l. 184'6" b. 33' dr. 9'9" s. 15 k. cpl. 104 a. 1 x 3" cl. Admirable. Creddock (AM-356) was launched 22 July 1944 by Willamette Iron and Steel Corp., Portland, Oreg.; sponsored by Miss N. I. Schmidleys; and commissioned 18 December 1945, Lieutenant (junior grade) J. C. Elliott, USNR, in command. Creddock departed Astoria, Oreg., 6 January 1946 and arrived at San Diego 4 days later. There she was placed out of commission in reserve 26 March 1946. Creddock was reclassified MSF-356 on 7 February 1955.' The record establishes a truncated U.S. career: commissioned 18 December 1945 - four months after the war ended - and out of commission in reserve three months later, with a single Astoria-to-San Diego transit as her only documented voyage.

- Limitations
- DANFS documents identity and service dates, not materials or asbestos content. The entry predates the 1967 disposal (no striking or transfer appears) and is silent on the hull's PCE-916 origin and laid-down date - NavSource and the yard table supply those. The spec block's 'dp. 530' conflicts with NavSource's 945 t and the class-typical ~650-ton light displacement - logged in gaps. Live NHHC page returns 404 (standing Batch-01 link-rot); verbatim mirror transcription cited.

- NavSource record for this hull: laid down 10 November 1943 by Willamette Iron and Steel Corp., Portland, OR; launched 22 July 1944; commissioned USS Creddock (AM-356) 18 December 1945; 'Naval Vessel Register of 1 January 1949 lists plan for decommissioning and placing in reserve as December 1945'; decommissioned 26 March 1946 at San Diego; reclassified Fleet Minesweeper (Steel Hull) MSF-356 on 7 February 1955; struck from the Naval Register 1 February 1967; transferred 31 March 1967 to Burma (Union of Myanmar) and renamed Yan Gyi Aung (M 42); 'Fate unknown.' Commanding officers: LTJG John Charles Elliott USNR (18 Dec 1945), LTJG Albert James Sommers USNR (21 Jan 1946), LTJG Edward Steven Gaiennie USNR (15 Feb - 26 Mar 1946). Spec block: 945 t, 184'6" x 33' x 9'9", 14.8 kts, complement 104; armament one 3"/50 DP, two twin 40mm, six 20mm, hedgehog, four K-guns, two depth-charge tracks; propulsion two 855-shp Busch-Sulzer 539 diesels, Farrel-Birmingham single-reduction gear, two shafts.

- NavSource is a compiled secondary database (drawing on NVR entries and contributor material); its register notes quote the NVR of 1 January 1949 secondhand. No materials or asbestos information. The Busch-Sulzer 539 engine attribution conflicts with Wikipedia's class-generic ALCO 539 infobox entry - logged in gaps; a specialist Myanmar article (wwiiafterwwii) independently confirms Busch-Sulzer BS-539 for this hull. 'Fate unknown' conflicts with later secondary reporting that the hull remains in Myanmar service - logged in gaps.

- Finding
- The builder's yard production table places this hull at Willamette Iron & Steel, Portland, as yard hull no. 42, carrying the dual identity 'PCE 916/AM 356' - corroborating at yard level that the hull was ordered and begun as PCE-905-class patrol craft escort PCE-916 and completed as Admirable-class minesweeper Creddock (AM-356), delivered 18 December 1945. Disposition column: 'Reclassified MSF 356 1955, to Burma 1967 as Yan Gyi Aung (M 42).' Corroborating secondary lists: NavalCoverMuseum designation index ('PCE 916 - CREDDOCK MSF 356 ex AM 356 ex PCE 916'); usnavy.skyrocket.de tables ('AM MSF 356 Creddock (ex PCE-916)'; PCE table '916 ... -> AM-356 Creddock'); uboat.net ship page 5932 (ordered 26 Jun 1943). Wikipedia's infobox gives the reclassification-to-AM date as September 1943 - i.e., before the 10 November 1943 laying down.

The September 1943 reclassification date is Wikipedia-only and unverified against a primary contract record. The Bureau of Ships contract file (NARA RG 19) is the unretrieved primary source that would confirm the PCE-to-AM conversion order and date. None of these sources contains materials or asbestos information.

- Finding
- Post-transfer record for this hull, from compiled secondary sources: transferred to Burma 31 March 1967 and renamed Yan Gyi Aung (M-42); classed as a patrol corvette. Navypedia lists 'in service (2019)' with the note 'minesweeping gear was removed prior transfer.' warsearcher.com lists the hull among Myanmar's two 'Admirable and PCE-842 class patrol corvettes,' 'still in ceremonial commission.' wwiiafterwwii (specialist blog, 2020) reports: purchased 31 March 1967 as UBS Yan Gyi Aung; reactivated at San Diego and sailed to Rangoon; WWII radar replaced with AN/SPS-5 before sailing for commonality with half-sister UBS Yan Tuang Aung (ex-USS Farmington PCE-894); minesweeping gear (if carried) removed during the 1980s along with ASW weaponry; AN/SPS-5 later failed and was replaced with a civilian navigation radar; reported decommissioned to reserve 1994, back in full service 1997, reported decommissioned again 2009 (Jane's omitted both ships), active again by early 2011; photographed in service 2016-2019; 'remarkably unchanged from the WWII baseline.'

[5]Najolia v. Northrop Grumman Ship Systems, Inc., 883 F. Supp. 2d 646 (E.D. La. 2012) [court_record]
- Locator
- Opinion text at *654 (S39-1 '85 per cent magnesia' passage; Gate affidavit on enforced specs); CourtListener cluster 8718087 (cluster-level URL cited; a same-numbered stub opinion in the index is a mismatched immigration case - data defect logged in batch-1136)
- Finding type
- asbestos_application
- Finding
- Published federal opinion reviewing record evidence in an asbestos case documents the Navy specification regime applicable to construction of this era: the Navy's General Specifications for Machinery, subsection S39-1 'Heat insulation and lagging for piping and machinery,' required insulation of '85 per cent magnesia' for the stated temperature ranges - a pipe covering and block-form insulation documented in that record as containing 12-18% asbestos fiber - and Chapter 39 of the Bureau of Ships Manual required thermal insulation on machinery and encouraged asbestos use; record evidence states military specifications 'affirmatively required the use of asbestos-containing thermal insulation.' This hull was built under U.S. Navy contract (PCE-905/Admirable program), so the spec regime is the applicable construction context.

- Limitations
- Documents the Navy specification regime, not this hull: the opinion's record evidence concerned a different vessel, the spec edition applicable to the PCE-916/AM-356 contract (ordered June 1943, laid down November 1943) is not itself quoted here, and a diesel minesweeper had no boiler or turbine plant (the S41-1 turbine context is steam-specific; S39-1 piping/machinery insulation is the applicable scope). Establishes that asbestos insulation was spec-required in Navy construction of the era - not that it was installed on or remains aboard this hull, nor causation or exposure.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming USS Creddock, AM-356, MSF-356, PCE-916, or Yan Gyi Aung was found in the public sources searched (see search_ledger). The litigation sweep is INCOMPLETE: the authenticated CourtListener API v4 was exhausted at its 2,800/day cap at research time (shared key; reset ~9.1h out) and could not be queried - per batch instructions the search was not retried into a ban; engine-level web searches on all name variants returned no qualifying litigation (the only ship-name litigation-adjacent hit was a mesothelioma.com minesweeper list page, a law-firm marketing page excluded per source rules).

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - WWII Navy construction specifications made asbestos insulation near-universal, the hull reportedly remains in Myanmar service 'remarkably unchanged from the WWII baseline,' and its material condition is undocumented. The CourtListener re-run (all name and hull-number variants) remains an open item; 'Creddock' is a distinctive coined name (low collision), so future hits would likely be genuine but still require verification. Does not establish or defeat any claim of exposure or legal eligibility.

- Finding
- Unretrieved archival path: unlike lend-lease hulls, this vessel WAS in U.S. commission (18 Dec 1945 - 26 Mar 1946), so NARA RG 24 deck logs exist for roughly three months - they would document fitting-out, the Astoria-San Diego transit, and inactivation work. The BuShips contract file (RG 19) for PCE-916 would carry the conversion order and material specifications. The 1967 transfer was a government-to-government sale (wwiiafterwwii: 'purchased'); the FMS/MAP case file would document any pre-transfer work at San Diego, including whether era materials were disturbed or removed. Myanmar Navy records for M-42 are the lead for the hull's 1967-present material history.
