- Finding
- DANFS 'Chimango I (AMc-42)' entry, as rendered by search-engine indexing of the live NHHC page and corroborated verbatim in substance by the hazegray.org DANFS mirror and by Wikipedia's DANFS-incorporated text: Chimango was laid down 18 January 1941 at Jacksonville, FL, by the Gibbs Gas Engine Co.; launched 8 March 1941; commissioned 3 June 1941. She trained at the Mine Warfare Base, Yorktown, VA, until 26 July 1941, when she rendezvoused with USS Goldfinch (AM-77) and USS Jacamar (AMc-47) to sail to Argentia, Newfoundland. On 15 June 1942 she was decommissioned and placed in service, continuing minesweeping and patrol duty at New York, NY, and Charleston, SC, until 20 December 1945. She was stricken from the List of Naval Vessels on 8 January 1946 and transferred to the Maritime Commission for disposal on 21 August 1947.

- In this research session, direct WebFetch of history.navy.mil failed with a TLS certificate-verification error, hazegray.org and navsource.org failed with DNS resolution errors, and web.archive.org fetches were blocked outright - a materially different network posture than prior batches that cited Wayback captures directly. The DANFS text above is therefore established via triangulation (search-engine indexing of the live NHHC page, the hazegray mirror, and Wikipedia's DANFS-incorporated prose all agreeing on wording and dates) rather than a single verbatim page fetch. It establishes identity, build/commission dates, training and transit, district service, and disposal-transfer dates - it contains no stat line (displacement/dimensions/complement/armament) and no asbestos or materials information.

- Gibbs Gas Engine Co. (Jacksonville, FL) yard-history compilation, directly fetched: the yard was founded in 1911 and built small wooden and steel vessels in both World Wars; its notable-vessels list records 'Chimango (AMc 42): Minesweeper, delivered June 3, 1941; sold 1947.' Post-WWII the company became Gibbs Corporation (ship repair until 1957, then steel shipbuilding); sold to Aerojet-General Shipyards Corp. in 1964, to Fruehauf Corp. in 1969, to Terex Corp. in 1989; all three resulting Jacksonville yards closed in 1992.

- Limitations
- Specialist compilation, not an official Navy record - directly fetched and matches the DANFS commissioning date (3 June 1941) under the label 'delivered,' corroborating builder and delivery timing. The 'sold 1947' notation does not identify a buyer, price, or subsequent fate, and is not fully reconciled with a separate search-derived NavSource claim that her final fate is unknown (see gaps). No asbestos or materials information; the yard's general wartime output (subchasers, patrol craft, tugs) is background only and does not establish anything about this hull specifically.

No entry was found in this list covering her earlier commissioned period (3 June 1941 - 15 June 1942).

- Limitations
- Confirms primary deck-log coverage exists for the 1942-1945 in-service period but is a finding-aid entry only - log contents themselves are unexamined and log format (digitized vs. not) was not separately confirmed in this pass. The apparent absence of a listed entry for the 3 June 1941-15 June 1942 commissioned period is notable and carried in gaps rather than assumed to mean no logs exist for that period - the finding aid may simply group coverage differently, or those logs may not have survived/been accessioned; not resolved here. These logs are the leading ship-specific lead for any repair, conversion, or materials entries bearing on asbestos.

[6]Secondary/specialist compilations (Wikipedia class-level articles for USS Accentor (AMc-36), USS Jacamar (AMc-47), USS Courlan (AMc-44); uboat.net Allied Warships database) describing the AMc coastal-minesweeper build program [other_primary]

- Finding
- Class/era background only: secondary compilations (Wikipedia, uboat.net, NavSource-style listings) describe a group of similarly specified wooden-hulled, single-diesel coastal minesweepers commonly styled the 'Accentor class,' with roughly 50+ hulls in the AMc-36 through AMc-91 range built in 1941, of which Chimango (AMc-42) is a member built at the same time as near-contemporaries such as USS Accentor (AMc-36, laid down 21 January 1941), USS Jacamar (AMc-47, launched 10 March 1941, commissioned 25 June 1941), and USS Courlan (AMc-44, launched 4 April 1941). A representative class-level specification set gives displacement 221 long tons, length 97 ft 6 in, beam 22 ft 6 in, draft 8 ft 11 in, speed 10 knots, complement 17, armament two .5 in machine guns, and propulsion one Cooper-Bessemer diesel of approximately 400 bhp.

- This row describes the build-program/class in general and is used strictly as background - it does NOT establish any ship-specific fact about Chimango and must never be read as such. It is the source of the class-level specification figures that conflict with the two ship-specific renderings (ev-04, ev-05); none of the three has been confirmed against a primary BuShips document in this research, and the conflict is carried in gaps rather than resolved by preferring one.

- historical_record
- Finding
- Name-collision disambiguation: a second USS Chimango exists. Search results identify 'USS Chimango (AMCU-20),' ex-LCI(L)-703, renamed and reclassified 7 March 1952, apparently never commissioned under that name (AMCU-7-class landing-craft-infantry-to-minesweeper conversion designation). The two hulls share only the name - AMc-42 was stricken from the Navy list in January 1946, more than six years before AMCU-20 was so named.

- Not confirmed against a primary NHHC/DANFS page in this research (no live DANFS entry for a second Chimango was directly located or fetched) - carried here strictly to prevent conflation of AMc-42 with any later 'Chimango' in litigation, archival, or deck-log searches. Establishes nothing about AMc-42 itself. If a primary DANFS or NVR record for AMCU-20 surfaces in a later pass, this row should be upgraded or corrected accordingly.

- Finding type
- asbestos_application
- Finding
- Peer-reviewed scholarship documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during World War II, and that federal wartime policy reserved asbestos supply for shipbuilding - the era and program under which this purpose-built diesel coastal minesweeper was designed, laid down, and delivered in 1941. For a small diesel-driven auxiliary of this type, era-consistent asbestos applications would have been confined to machinery gaskets and packing, possible exhaust lagging, electrical insulation, and friction materials rather than the boiler/steam-line thermal insulation characteristic of steam vessels.

- Era/program-level scholarship; does not name this vessel or vessel type and does not establish that asbestos was or remains aboard this hull, nor quantity, location, condition, exposure, or causation. The article's emphasis is steam-driven production shipbuilding; application to a single-diesel coastal auxiliary is weaker still. Absence of a steam plant narrows but does not eliminate era-typical asbestos pathways.

Madoff Investment Securities LLC (In re Madoff Securities), 501 B.R. 26 (S.D.N.Y. 2013) - a securities-fraud/bankruptcy clawback proceeding with no connection to a vessel, the Navy, or asbestos; the match is a name collision (a fund or entity named 'Chimango' referenced somewhere in the opinion text or docket). Searches for the exact hull-number strings '"AMc-42"' and '"AMC-42"' each returned the same single hit (count=3, top result): Geltzer v. Artists Marketing Corp. (In re Cassandra Group), 338 B.R. 583 (Bankr. S.D.N.Y. 2006) - an unrelated bankruptcy-avoidance proceeding, again a name/number-string collision.
