- Authoritative wartime BuShips publication naming this hull - confirms builder and the three construction milestones. Scanned-table OCR renders the hull number partially ('LCI(L) 9..') but the row position between LCI(L)-965 and LCI(L)-967 and the exact date triple are unambiguous and match NavSource independently. Contains no materials, insulation, or asbestos information; supports no asbestos claim.

- Authoritative for the administrative identity chain but thin: DANFS's '(q.v.)' cross-reference to an LSIL-966 entry does not resolve to any narrative entry in Vol. IV, and the volume contains no WWII service entry for LCI(L)-966/LSIL-966 at all. 'Reverted to original status' is the entirety of the official record on the outcome; the explicit statement that conversion was canceled 1 July 1954 comes from the NavSource compilation (secondary), not DANFS. Supports the batch instruction that AMCU-31 is a consolidation alias, not evidence of minehunter service.

- Finding
- DANFS disambiguates three separate Medrick associations: (I) the first Medrick - ex-PCS-1464 reclassified AMc-203 and named 10 Jan 1945, an Accentor-class coastal minesweeper built by Astoria Marine Construction Co., Astoria, Oreg. (laid down 22 May 1943, commissioned 8 Jan 1944, minesweeping out of Pearl Harbor, decommissioned 9 Jul 1946, struck 28 Aug 1946, delivered to Maritime Commission 16 Dec 1947); (interstitial) the name Medrick assigned to AM-369 on 11 Apr 1944 - construction by Puget Sound Bridge & Dredging Co., Seattle, canceled 6 Jun 1944 before completion; (II) this hull, ex-LSIL-966, named under the same 7 Mar 1952 AMCU naming wave. The name itself denotes a small gull or tern of the family Laridae.

- Disambiguation row - establishes that 'Medrick' hits in any index may refer to one of three different hulls (one real minesweeper, one canceled AM, one paper AMCU).

Under the manual's 'only 1 star for participation in 1 or more' rule these cluster into four operation groups - Leyte (P31), Luzon (P32), Manila Bay-Bicol (P41), Consolidation of the Southern Philippines (P39).

Operation codes and official engagement names/dates verified against the HyperWar transcription of Part III (e.g., P31-7 'Ormoc Bay landings 7-13Dec44', P39-2 'Visayan Island landings 1Mar-20Apr45' covering Cebu). Discrepancy with NavSource's campaign table - which adds a Morotai landing (P28-8, 15 Sep 1944) and reports five battle stars - is flagged in gaps. Documents combat participation only; no asbestos or materials information.

- Specialist secondary compilation - detailed but non-official; its history is credited to the Turner Publishing LCI volume, not a Navy document. Consistent with the official SDB construction row and substantially with the NAVPERS engagement list, but three ship-level discrepancies vs. official/manual sources are logged in gaps (Morotai credit, Visayan and Mindanao dates, complement figures, decommissioning day). The explicit 'conversion canceled 1 July 1954' wording is this compilation's gloss on the DANFS reversion record. Contains no asbestos information; supports no asbestos claim.

- Finding
- DANFS entries for sister landing craft document the program this hull's paper reclassification belonged to: LSILs were reclassified LSIL 28 Feb 1949 (fleet-wide administrative action, e.g. LSIL-884), then named and redesignated AMCU under the same 7 Mar 1952 bird-naming wave as Medrick. Converted sisters were recommissioned at Charleston, S.C. and served as 'underwater mine detectors' in the 4th and 6th Naval Districts (e.g., Minivet 'served for 2 years in the 4th Naval District'; Longspur 'assigned to the 6th Naval District for harbor defense'; Mallard 'reactivated at Charleston... operated on the east coast as an underwater mine detector'). Medrick's documented outcome - reclassified, named, then reverted to LSIL-966 on 1 Jul 1954 with no conversion or commissioning - is the paper-only variant of the same program.

- Finding type
- asbestos_application
- Finding
- Era/design inference: this class carried a twin-screw diesel plant (G.M. Diesel '6051 series 71' engines, 2,320 shp, G.M. reduction gears, diesel service generators - SDB 1945 v2) with no boilers and no steam system. The asbestos applications that dominate WWII steam-ship exposure - boiler and fireroom insulation, steam-drum covering, main and auxiliary steam-line lagging - were therefore structurally absent on this type. Residual era-standard asbestos applications remain possible in machinery gaskets and packing, electrical cable insulation, deck covering or cement compounds, and winch/windlass brake linings - consistent with general WWII naval construction practice but unverified for this class.

- Inference from the documented machinery configuration - NOT a hull record and NOT a class materials schedule. No insulation specification, material list, or survey for the LCI(L)-351 class was located; the diesel-plant observation bounds the exposure profile downward relative to steam vessels but establishes no asbestos content, quantity, location, or individual exposure either way.

- Era-level documentation of asbestos use in naval construction generally; does not name this vessel, class, or builder yard and - significantly for a diesel craft with no steam pipe system - the surveyed pipe-covering pathway maps poorly onto a 159-ft landing craft. Establishes nothing about this hull's materials, condition, or any individual exposure. (The study's exculpatory 'not a dangerous occupation' conclusion has since been heavily criticized.)

CourtListener opinion sweeps for 'USS Medrick', 'LCI(L)-966', 'LCI-966', 'AMCU-31', and 'LSIL-966' returned zero results; bare 'Medrick' returned 19 opinions and 81 dockets, all person-name collisions (bankruptcy, contract, ERISA, family law) - none naming a vessel or involving asbestos. No MARAD/NDRF custody record exists - the hull was Navy-held throughout and never entered Maritime Administration custody. The hull is not extant as a museum or surviving hulk, so no present-day hazmat/disclosure surface exists.
