- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - its milestone dates generally track NVR/DANFS but no DANFS entry exists for this hull to cross-check, and several items (decommission month/day, PCC reversion date, stricken date, final fate) are absent from every accessible source. Contains no asbestos content.

Commanding officers (WWII duration): Lt.(jg) R.S. Mueller USNR (26 Jan 1944 - Jan 1945); H.T. Wilson USNR (Jan-Feb 1945); J.H. Ries USNR (early 1945 - mid/late 1945); F.X. Guddy USNR (mid/late - late 1945). Documented operation: convoy UGS-47 - PC-1169 (Lt.(jg) Mueller) among the nine U.S. patrol vessels, plus the French Dague, on passage to the Mediterranean with the Hampton Roads departure of 4 July 1944; fuelled at sea from USS Escalante 9 and 16 July; arrived Bizerta 23 July 1944 with the escort group.

CO list covers WWII duration only and dates are approximations ('early', 'mid/late'). No asbestos content. The July 1944 UGS-47 passage corroborates the hull's Atlantic-Mediterranean service window independently of NARA file-unit titles.

The file-unit titles document participation in the invasion of Southern France (Operation Dragoon, 15 August 1944), consistent with her subsequent reclassification as amphibious control craft PCC-1169.

(2) A National Archives photo showing PC-1169 moored inboard of PC-822 with an unidentified PC astern, gasoline barge YOG-71 on the opposite pier, at Coco Solo Naval Station, Panama Canal Zone, circa 9-12 October 1945 - placing the hull in the Canal Zone in the immediate post-war period.

[7]Era inference built on: NavSource specifications (diesel PC-461-class combatant built 1943-44); GAO HRD-80-2 (ev-07: Navy asbestos insulation use through the early 1970s); WWII-era small-combatant construction practice [other_primary]

- Finding type
- asbestos_application
- Finding
- A PC-461-class submarine chaser built 1943-44 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small diesel combatant of this type and period were thermal insulation around hot machinery and piping, diesel-exhaust lagging, gaskets, valve packing, and electrical insulation - concentrated in the engine room and machinery spaces of a compact 173-foot hull. As a diesel-powered craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply, but the confined-space exposure dynamic of a small machinery compartment applies with full force.

- Finding
- GAO reviewed the Navy's efforts to protect workers from asbestos exposure at the Long Beach and Norfolk Naval Shipyards, including 'the use of asbestos in Navy ships, the cost of removing asbestos from Navy ships, and compensation programs for asbestos-related disabilities'; per the product page, the Navy's 1975 policy was to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed for repairs, modified in 1979 to add selective replacement in high-maintenance areas - documenting that asbestos insulation was in general shipboard use throughout this hull's construction (1943-44) and service era (1944-50).

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, donation-condition record, or verified litigation naming USS PC-1169 / PCC-1169 / Escandido was found in the public sources searched. CAVEAT: CourtListener could not be queried this session - authenticated API via the fleet helper returned daily-quota-exhausted (server-directed wait ~3.2 h); logged as blocked in search_ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case - only unrelated name collisions (Escondido CA real-estate/geographic references, Pegasus Airlines flight PC1169) and law-firm-free results; no law-firm marketing pages asserting 'asbestos aboard PC-1169' were even located.

- Absence of a located public record does not prove absence of asbestos aboard - and the litigation repository search is a genuine open gap (quota-blocked, not run). Deck-log text, war-diary content, Sullivan yard work packages, and any disposal/scrapping records are digitized-or-undigitized leads not yet extracted. Does not establish or defeat any claim of exposure or legal eligibility.

[10]Name-spelling cross-check: NHHC NH 94910 official title 'USS PC-1169, later ESCONDIDO' vs NavSource/Wikipedia 'Escandido'; navalmarinearchive shipbuilding table independently carries 'Escondido' [other_primary]

- Finding type
- historical_record
- Finding
- CORRECTION-FLAG: the official U.S. Navy photographic catalog (NHHC, photo NH 94910) titles this hull 'USS PC-1169, later ESCONDIDO' - with 'o' - while NavSource (the source of the fleet's spelling) and Wikipedia-derived lists carry 'Escandido'; the navalmarinearchive Sullivan Dry Dock construction table independently prints 'Escondido'. A U.S. city of Escondido exists in San Diego County, California; no place named 'Escandido' was located. NHHC being the authoritative Navy source, 'Escondido' is likely the official 15 February 1956 name and 'Escandido' a propagated transcription variant - but this record carries the batch-list spelling 'Escandido' as primary with the conflict fully disclosed.

If 'Escondido' is confirmed official, the fleet's vessel list and this slug carry the variant spelling.
