- Finding type
- vessel_history
- Finding
- Official Chilean Navy history identifies Papudo as a North American PC-1638-class submarine chaser and the first warship built at ASMAR Talcahuano to U.S. Navy plans. Its keel was laid 30 December 1968, it was baptized 20 April 1970, and it was officially delivered to the Chilean Navy 19 November 1971. The page records 477 tons displacement, 3,550 HP machinery, 20-knot maximum speed, 53 m length, 3.1 m draft, four mortars, one Hedgehog, four 20/63-mm machine guns, and one 40/56-mm machine gun. It was sold/enajenado under D.S. (M) No. 16 on 22 September 1993.

- Limitations
- This official history establishes identity, construction, dimensions, machinery power, armament, and Chilean disposition; it does not state a U.S. Navy commissioning, complement, propulsion type, asbestos content, asbestos survey, abatement, or present location.

[3]NavSource Online, Submarine Chaser Photo Archive index, offshore procurement PC-1635 through PC-1646 (verified live 2026-10-03) [other_primary]

- Offshore Procurement under the Mutual Defense Assistance Program, PC-1635 to PC-1646 index block
- Finding type
- vessel_history
- Finding
- NavSource's offshore-procurement index lists PC-1646 as built in Chile as Papudo (P 37), distinguishing it from PC-1644 Peder Skram and PC-1645 Herluf Trolle built in Denmark and from the Chilean PC-1647/PC-1648 entries. This cross-check supports the U.S. accounting hull number and the Papudo identity.

- Limitations
- NavSource is a photographic-history compilation rather than the Chilean Navy's registry; it does not establish asbestos content, a U.S. Navy commission, or post-1993 disposition. The live .net URL is cited; the obsolete navsource.org domain is not used.

[4]Historia Naval, 'Construcción naval en Chile' (official-history publication hosted by historianaval.cl, Papudo section, verified live 2026-10-03) [other_primary]

- PDF page 28, 'Cazasubmarinos Papudo' section
- Finding type
- historical_record
- Finding
- The Chilean naval-history publication describes Papudo as the first line warship and high-technology vessel built in Chile by ASMAR Talcahuano, designed to the U.S. PC-1638 class. It repeats the 30 December 1968 keel-laying, 20 April 1970 baptism, and 19 November 1971 delivery dates; records 477 tons, 53 m length, 3.1 m draft, 3,550 HP, and 20 knots; and states that the vessel served from Iquique and was decommissioned and sold on 22 September 1993 after 22 years.

- Finding type
- gov_survey
- Finding
- CDC/NIOSH identifies asbestos as one of the chemical hazards associated with shipyard manufacture, repair, maintenance, and dismantling work. This supplies general shipyard context relevant to the ASMAR construction and later vessel work, not a finding about Papudo's materials.

- Finding type
- asbestos_application
- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, material specification, museum record, or other authoritative document was found that identifies asbestos aboard PC-1646/Papudo. The located official history documents construction and service only.

- Limitations
- A negative public-source finding does not prove that asbestos was absent aboard the hull. It establishes only that no qualifying record was located in the sources searched; class/era and shipyard context remain non-ship-specific.

- Finding type
- historical_record
- Finding
- The exact-name opinion query returned zero results. The exact-name docket, PC-1646 opinion, and PC-1646 docket requests were attempted through the authenticated helper but did not complete because the shared fleet pacing budget was unavailable during this session. No asbestos-qualified variant was run. Litigation status therefore remains open/blocked, not negative.
