- Finding
- USS Cotinga (AMCU-22) was the former LCI(L)-776, renamed and reclassified AMCU-22 on 7 March 1952. This is the full extent of the identity/history record given in the English Wikipedia disambiguation entry for 'USS Cotinga,' which states it incorporates public-domain Dictionary of American Naval Fighting Ships (DANFS) text.

- Limitations
- This is the only ship-specific identity fact located and reads as a single-sentence excerpt of a fuller DANFS entry; the NHHC DANFS page itself could not be retrieved this session (see evidence row 02) to confirm no additional narrative exists. Contains no asbestos, materials, or condition information whatsoever; supports no asbestos claim of any kind.

- Finding
- Attempted direct retrieval of the Naval History and Heritage Command (NHHC) DANFS entry for Cotinga, and of the DANFS entry for sister hull LCI(L)-777 (which would be expected to name LCI(L)-776 as a sister ship built in the same block), to independently confirm builder, construction dates, and the 3 August 1944 commissioning date carried in this batch's task specification.

- NHHC's live site could not be fetched this session (HTTP 503 on repeated attempts across multiple hours), a standing access problem for this domain already noted in BATCH-01-REPORT.md ('Live DANFS pages returned 404... for automated fetches'). This row establishes only that the primary source is presently inaccessible to this research process, not any fact about the vessel. The 3 August 1944 commissioning date, and any builder/keel/launch data, therefore remain unconfirmed against a directly-read primary source this session.

- Finding
- Cross-hull pattern check (class/era, not ship-specific): every documented AMCU-7-class sister hull converted from a WWII LCI(L) shows the same three-stage redesignation sequence Cotinga's aliases imply - original LCI(L) hull number, reclassified LSI(L)/LSIL on 28 February 1949 (fleet-wide), renamed for an AMCU 'Coastal Minesweeper (Underwater Locator)' identity in 1952 (Cotinga specifically: 7 March 1952, per evidence row 01), and redesignated MHC (Coastal Minehunter) on 7 February 1955 (fleet-wide, per most sister-hull sources). Examples verified: USS Oriole (ex-LCI(L)-973; LSIL-973 28 Feb 1949; AMCU-33 Mar 1952; MHC-33 1 Feb 1955); USS Jacamar (ex-LCI(L)-870; LSIL 28 Feb 1949; AMCU-25/renamed 7 Mar 1952); USS Longspur (ex-LCI(L)-884; LSI(L)-884 28 Feb 1949; AMCU-28/renamed 7 Mar 1952; MHC-28 dated 7 Feb 1953 in this one source, inconsistent with the 7 Feb 1955 date given for other sister hulls); USS Kestrel (AMCU-26, MHC-26 'in February 1955'); USS Sanderling (AMCU-49 1 Feb 1955, MHC-49 7 Feb 1955).

- Limitations
- This is a documented FLEET/CLASS pattern used only to explain the aliases given for this hull (LCI(L)-776, LSIL-776, MHC-22); it does not itself name Cotinga/hull 22 and does not establish that hull 22's own redesignation dates matched the fleet norm exactly, that its conversion was completed, or that it was ever recommissioned under AMCU-22 or MHC-22 (see gaps). Contains no asbestos information; supports no asbestos claim.

- Class specifications for the AMCU-7-class conversion of LCI(L)-351-class large infantry landing craft (the class Cotinga's original LCI(L)-776 hull belonged to): length 158 ft 5.5 in, beam 23 ft 3 in, displacement 216 tons light / 234 tons landing / 389 tons loaded; propulsion 2 shafts each driven by 4 General Motors 6-71 diesel engines in a 'Quad Diesel' unit (8 engines, ~1,600 bhp total) with variable-pitch propellers; maximum speed 16 knots. As-built LCI(L) troop/cargo capacity and light armament are separately documented for the parent LCI(L)-351 class and are not repeated here as they predate the minesweeper conversion.

- Finding type
- asbestos_application
- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as fireproofing and insulation in U.S. shipbuilding during WWII, and that the Navy's 1943 'Minimum Requirements for Safety and Industrial Health in Contract Shipyards' regulated asbestos work at every yard building or repairing Navy vessels - a requirement that by its terms covered landing-craft and small-auxiliary construction such as the LCI(L)-351-class hull this vessel began as, not only large combatants. Diesel-engine installations of the era (the propulsion type used by this class, per evidence row 04) commonly used asbestos-containing exhaust-manifold lagging, gaskets, and packing, and small-craft engine-room and berthing-space insulation of the period commonly used asbestos felt or millboard.

- Program/era-level scholarly documentation of Navy-wide shipbuilding asbestos use and regulation; does not name this vessel, this hull's builder, or the LCI(L)-351/AMCU-7 diesel plant specifically, and does not establish that asbestos was or remains aboard this hull, its quantity, location, condition, or any exposure or causation fact. No LCI(L)-351/AMCU-7-specific engineering manual (of the kind available for Liberty-ship steam plants) was located to move this above class/era inference.

- CourtListener API v4 searches for this vessel and every alias/designation in its hull-consolidation set - 'Cotinga', 'AMCU-22', 'LCI(L)-776', 'LSIL-776', and 'MHC-22' - returned no qualifying opinion, docket, or RECAP filing naming this hull. Broad-text hits on the bare word 'Cotinga' were unrelated matters (an environmental-litigation docket, unrelated bankruptcy and copyright cases with an attorney or party surname coincidentally matching) and were classified as name collisions, not vessel litigation.

- Finding
- No qualifying ship-specific asbestos record of any kind - survey, abatement contract, hazmat disclosure, museum/preservation record, or litigation - was located for this hull under any of its names (LCI(L)-776, LSIL-776, AMCU-22/Cotinga, MHC-22) in the official/authoritative sources searched this session (NHHC/Wikipedia-DANFS mirror, CourtListener). This negative finding is reported as a first-class result, consistent with this dataset's discipline for genuinely thin records, and is not a placeholder for a claim.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1944-built diesel landing-craft hull converted for 1950s minesweeper service is era-consistent with asbestos-containing construction materials, per the class/era inference in evidence row 05. This row does not establish presence or absence of asbestos, and does not establish or defeat any exposure or legal-eligibility claim. Several standing access gaps (NHHC 503s, NavSource DNS/network-policy blocks) mean this negative finding may reflect access limitations rather than a fully exhausted search - see gaps.
