- Finding
- Commissioning and decommissioning documentation for this hull: the file opens with the 'MUSTER ROLL OF THE CREW of the U.S.S. PC-795 - COMMISSIONING REPORT' listing ~58 enlisted men all 'Date first received on board 10 June 1944'; the quarterly forwarding sheet is annotated 'Comm. 6-10-44 to 3-8-46 Decom.', certified by W. T. BROWN, Lt., USNR, Executive Officer, and approved 1 July 1944 by C. H. JOHNSON, Lt., USNR, Commanding Officer (received by the Bureau 10 July 1944). The final muster page (period ending 8 March 1946) reads 'Last report for the U.S.S. PC-795. Decommissioned as of 8 March 1946' (received by the Bureau 1 May 1946), transferring the last 33 men to personnel separation centers (Bainbridge, Great Lakes, New Orleans, St. Louis, Camp Wallace TX, Terminal Island San Pedro, Bremerton), to the Columbia River Group reserve organization at Astoria, OR ('COLRIVGRP ASTORE', 'COMCOLRIVGRP'), and one man to USS PC-1224.

Fate unknown.' Specifications: displacement 450 t.; length 173'8"; beam 23'; draft 10'10"; speed 20.2 kts; complement 65; armament one 3"/50 dual-purpose mount, one 40mm mount, five 20mm guns, two rocket launchers, two depth-charge tracks; propulsion two 1,440-bhp Hooven-Owen-Rentschler R-99DA diesel engines, Westinghouse single reduction gear, two shafts. Call sign Nan-Uncle-Victor-Roger. Page states plainly: 'There is no DANFS History currently available for PC-795.'

- The NARA catalog's indexed full text places 'PC-795' inside a coherent West-Coast command and personnel structure across her commissioned life. Command records: Fleet Training Center, Naval Station, Long Beach (Part III, 4/1/44-7/31/44), consistent with shakedown training; COM 11 (11th Naval District, San Diego) war diary 7/44; COMNORPAC war diary 6/44; COMWESTSEAFRON (Commander Western Sea Frontier, San Francisco) war diaries 6, 7, 8, 9, 10, 11/44 and 1, 2, 3, 4, 5, 6, 7, 8, 9/45; HQ NW Sector Western Sea Frontier, 4/15/44-7/1/46; COM 13 (13th Naval District, Pacific Northwest) war diaries 7, 11/44, 7, 8, 11/45, and 3/46 - the month of her decommissioning into the district's reserve basin; a 'Composition of Task Forces - July 1944' staff document (MR404(2) Sec. 19); the 'Haida, January 1945' file unit; and 'Commander, Columbia River Group, Pacific Reserve Fleet, 12/1/45-1/1/49' (NAID 190113550, 565 images) - the unit history of the reserve organization her crew was transferred into at decommissioning. Other vessels' records: USS BRIGHT war diary 6/30-8/31/44; USS Dent (DD-116/APD-9) record 8/44; a 'USS PC-567 to USS Romulus (ARL-22)' file unit. Personnel pipeline: muster-roll file units for Naval Hospital Long Beach (7/44-12/44), Naval Hospital Bremerton (1945-49), Hospital Seattle (7/44-4/45), Receiving Station Bremerton (3/45), MC Air Station El Centro (1943-46), YMS-121/131/134 muster rolls, and individual WWII personnel files - the record trails of sailors who served aboard or transferred through this hull. No indexed 'PC-795' hit places the hull outside the continental West Coast establishments. Two hits warrant caution at item level: a USS Prairie war diary for 12/42 predates her launching and is necessarily a coincidental/OCR-level match; and a COMNORWESSEAFRON (Northwest Sea Frontier, Seattle) war diary for 2/1-4/15/44 falls in her fitting-out window before commissioning - plausibly a district delivery/readiness reference but unverified. Index hits are leads, not confirmations.

The negative inference (no forward-area hits) is limited to digitized/indexed NARA holdings. The 'Composition of Task Forces July 1944,' 'Haida January 1945,' and COMNORWESSEAFRON (fitting-out window) matches could reflect list references, delivery scheduling, or OCR noise at item level.

- Finding
- A diesel-powered PC-461-class submarine chaser built 1943-44 at a Navy contract yard sits inside the documented WWII naval-construction asbestos era: the 1946 Fleischer/Drinker survey of Navy and contract yards documents amosite pipe covering, asbestos cloth, and asbestos cement as standard pipe-covering materials in naval vessel construction, and GAO documents Navy-wide asbestos insulation use into the early 1970s. Era-standard applications aboard a small diesel combatant of this period were thermal insulation, diesel-engine and exhaust-system lagging (this class discharged main-engine exhaust over the side near the waterline per the USNI class survey), gaskets and valve packing throughout machinery spaces, electrical insulation and cable, deck coverings, and accommodation-space insulation. The hull carries no boilers or steam plant - the boiler/turbine lagging pathway does not apply.

- Finding
- The landmark US government industrial-hygiene survey of WWII naval-vessel construction: pipe coverers at two Government navy yards and two Navy contract yards were examined (1,074 X-rayed; 3 asbestosis cases, all 20+-year pipe coverers), with dust counts and material analysis across seven pipe-covering operations. The pipe covering 'frequently employed was amosite' (a magnesium-iron silicate asbestos), and 'much asbestos cloth and asbestos cement were likewise used.' Documents that amosite insulation materials were standard in naval-vessel construction during the period this hull was built at a Navy contract yard.

- No qualifying ship-specific asbestos record located: no asbestos survey, material schedule, abatement contract, hazmat disclosure, or litigation naming PC-795 was found in the public sources searched. There is no DANFS entry - unnamed PCs were outside DANFS coverage and NavSource states none exists; the NHHC candidate URL returns 404. NVR carries no entry (disposed pre-1987). The MARAD Vessel History Database contains no record for this hull (searched PC-795/PC 795/795). CourtListener: three of the four prescribed base queries completed - exact-name opinion '"USS PC-795"' (type=o) returned zero hits; exact-name docket '"USS PC-795"' (type=r) returned zero hits; hull-number opinion '"PC-795"' (type=o) returned 3 hits, ALL Indiana post-conviction docket-number collisions (20A-PC-795 Neeb v.

The hull-number docket query '"PC-795"' (type=r) remained blocked by the fleet-wide pacing limiter across repeated attempts - logged as blocked in search_ledger, not as a negative result.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943-44 steel hull in the documented Navy asbestos era is consistent with era-standard ACM in machinery/gasket applications. The litigation-repository gap is partially open: three of four CourtListener base queries are complete (one zero-hit pair on the exact name; one all-collisions result on the hull number), but the '"PC-795"' docket-type base query could not be completed this session (fleet pace limiter) and must be re-run - on the collision pattern observed, qualifying asbestos content is unlikely but unverified. Deck logs (RG 24, coverage to 6/30/1945) and the wartime command war diaries indexing this hull are undigitized leads for availability/maintenance events. Does not establish or defeat any claim of exposure or legal eligibility.
