- Ch. IX, ARD design and ARD-2 construction-program paragraphs
- Finding type
- asbestos_application
- Finding
- The BuDocks official history describes the ARD type as a one-piece welded-steel ship-form dock 'equipped with its own diesel-electric power plant, pumping plant, repair shops, and crew's accommodations,' with quarters and messing in the wing-wall B deck, a hull-repair shop in the bow, and four railway-type diesel engines directly connected to electric generators. ARD-8 is one of the six 4,200-ton/483-ft docks of the ARD-2 type constructed in 1942-1943 under this program. Asbestos is not mentioned; the description establishes the plant categories in which era-typical asbestos-containing insulation, gaskets, packing, and electrical materials were used.

- Class/design documentation - describes the ARD/ARD-2 type generally and does not name ARD-8; the source never mentions asbestos. Any asbestos presence aboard this hull is era/class inference, not ship-proven. Establishes nothing about quantity, location, condition, individual exposure, or causation.

- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and program under which this 1943 welded-steel Navy dock was built - and that wartime demand drove unprecedented asbestos utilization aboard naval and merchant-type construction.

- NavSource Service Ship Photo Archive entry for USS ARD-8 (ARD-2 class): built by Pacific Bridge Co., Alameda, CA (laid down and launched dates not recorded); commissioned 1943-08-23 with LCDR Christ A. Rancich in command; assigned in WWII to the Asiatic-Pacific Theater at Pearl Harbor and Midway Island; decommissioned 1946-10-01; stricken from the Naval Register 1979-12-20; transferred under the Security Assistance Program to Peru 1980-09-01. Register-derived specifications: 4,200 t light, 482 ft 7 in, beam 71 ft, draft 5 ft, two single 20 mm mounts, complement 6 officers and 125 enlisted; call sign NDVN; awards American Campaign Medal, Asiatic-Pacific Campaign Medal, WWII Victory Medal. No DANFS narrative exists for this vessel.

- NavSource is a secondary archive republishing register/NVR-derived data and donated crew photos - the milestones match the NVR-derived Japanese-language compilation (uswarships.jounin.jp) but neither is the register itself. The 1979-12-20 strike and 1980-09-01 transfer dates conflict with Peruvian-side and shipyard-compilation reports placing the physical handover ca. 1960-61 (see ev-08 and gaps). No asbestos information; supports no asbestos claim.

Temporary patches were installed over the holes in the forward torpedo room pressure hull and the outer plating of MBT Nos. 2B, 6B and 6D. The ship departed Midway on 23 December for Navy Yard, Mare Island.'

- NavSource crew-photo captions (photos contributed by ARD-8 crewmember PTR3C Clayton E.

A Japan-based compilation of official docking records likewise records Cockatoo docking in ARD-8 at Pearl Harbor in February 1946.

- Peruvian service as floating dock ADF-107 at SIMA Callao: Peruvian state research repository (CONCYTEC/alicia) indexes Universidad Cesar Vallejo engineering theses (2017, 2018) analyzing maintenance planning for 'el dique flotante ADF 107' at SIMA-Callao; defense-press reporting (Peter Watson, Jan 2022, reposted zona-militar) describes SIMA Perú commissioning a structural evaluation of ADF-107 - built in 1943 and 'arriving in Peru in 1960' - citing corrosion in the lateral tanks and cracked suction piping; shipbuildinghistory's Pacific Bridge yard list gives 'ARD-8 ... Aug-43 ... To Peru 1961 as ADF 107.' ADF-107's Peruvian-reported usable length 125.96 m matches the ARD-2 class 413-ft internal basin. US register milestones remain stricken 1979-12-20 and Security Assistance Program transfer 1980-09-01 (NavSource).

- Limitations
- Secondary-source consensus: physical handover to Peru ca. 1960-61 vs US register title transfer 1980 - reconciliation (loan with retained US title, then strike/sale) is inferential; no primary Peruvian Navy or US transfer document located. The 2022 report describes deteriorated condition, not asbestos content; nothing here is an asbestos finding. ADF-107 = ex-ARD-8 identity is strong (1943 build date + matching internal-basin dimension) but not confirmed by a single official bilingual source.
