- Finding
- NavSource record for this hull: PC-461-class submarine chaser laid down 6 February 1943 at Commercial Iron Works, Portland, Oregon; launched 22 March 1943; commissioned USS PC-790, 23 March 1944; transferred to the War Shipping Administration in June 1948; transferred to Cuba in 1956 as the Coast Guard vessel Baire (PE 203); 'Lost during the Cuban revolution.' Call sign Nan-Uncle-Xray-Item; page notes she 'served the Navies of the United States and Cuba.' Specifications: displacement 450 t.; length 173'8"; beam 23'; draft 10'10"; speed 22 kts.; complement 65; armament one 3"/50 dual-purpose mount, one 40mm mount, three 20mm guns, two depth-charge projectors, two depth-charge tracks, two rocket launchers; propulsion two 2,560-bhp Hooven-Owen-Rentschler RB-99DA diesel engines with Westinghouse single reduction gear on two shafts. NavSource states explicitly that no DANFS history exists for PC-790.

- Limitations
- NavSource is a volunteer-maintained archival photo index compiled from Navy records, not a Navy adjudicative or registry document; its dates and specifications generally track official sources but it does not itself establish asbestos content, individual exposure, or the disposal/transfer instruments. 'Lost during the Cuban revolution' is imprecise - the dated sinking (17 April 1961, Isle of Pines) rests on secondary sources (see ev-06). No stricken or decommissioning date is given on the page.

- Finding
- Secondary-source timeline for this hull: ordered 27 February 1942; decommissioned 12 February 1946; 'Transferred to Cuba in 1956 being renamed Baire.' Commanding officers listed: Richard Stiegler, USNR (23 Mar 1944 - early 1945); James L. Sharp, USNR (early 1945 - mid/late 1945); Paul C. Farmer, USNR (mid/late 1945 - late 1945). Sole notable event: 10 February 1945, USS Seahorse (SS-304, T/Cdr. H.H. Greer, Jr., USN) departed Mare Island / San Francisco for Pearl Harbor, escorted out by USS PC-790 (Lt. J.L. Sharp, USNR) - drawn from Seahorse's patrol reporting.

- Finding type

- Finding
- The builder's-yard construction table lists PC-790 as Commercial Iron Works yard hull number 63, a 173-foot Navy sub chaser delivered 22 March 1944, disposition 'To Cuba 1956 as Baire (PE 203), lost in revolution' - corroborating the commissioned date (commissioned 23 March 1944, the day after the recorded delivery) and the 1956 Cuban disposal. The same table records the Portland yard's PC production run (hulls 49-83, PC-776 through PC-810) and its sister-hull fates, mostly 'Sold 1948' or foreign transfer.

'Lost in revolution' is imprecise against the dated 17 April 1961 sinking (ev-06). Yard-level production facts are context for the builder, not asbestos evidence for this hull.

- Finding
- The contemporaneous Jane's entry (published while Baire was in Cuban service) records: 'BAIRE (ex-Tribesman, ex-PC 790). Displacement: 295 tons standard (450 tons full load). Dimensions: 170 (w.l.), 173 (o.a.) x 23 x 7.5 (mean), 10.5 (max.). Guns: 1-3 inch d.p., 50 cal., 1-40 mm. AA., 2-20 mm. AA. Machinery: 2 Hamilton diesels. 2 shafts. B.H.P.: 1,600 = 22 kts. Complement: 66. Notes: Former United States submarine chaser. Pennant No. PE 203. Built by Commercial Iron Works, Portland, Oregon. Laid down on 6 Feb. 1943. Launched on 22 Mar. 1943. Completed on 23 Mar. 1944. Commissioned in 1944. Formerly of Honduran registry prior to purchase by Cuba in 1956. Acquired by the Cuban Navy and re-armed for employment in the coastal patrol.' Documents the Honduran-registry 'Tribesman' interlude and confirms pennant PE 203, Cuban purchase in 1956, and a reduced Cuban-era outfit (two 20mm guns vs three in U.S. service; 1,600-bhp 'Hamilton' diesels vs 2,560-bhp H-O-R RB-99DA).

- Jane's is a commercial reference annual, not a government record; its 'Hamilton diesels' attribution conflicts with NavSource's Hooven-Owen-Rentschler RB-99DA listing (possible re-engining, or a Jane's error - unresolved, carried in gaps). The OCR scan may corrupt figures (e.g., '295 tons standard'); NavSource/Colton corroborate the identity chain (ex-PC 790, PE 203) independently. Does not establish any material content.

- Navypedia Cuba escorts, BAIRE page - name/fate table + 'Naval service' line
- Finding type
- vessel_history
- Finding
- Navypedia dates the loss precisely: 'Baire sank at dosk [dock] at Isle de Pines 17.4.1961 during an abortive coup' (the Bay of Pigs invasion), fate field 'sunk 17.4.1961.' It records Baire as 'ex-Tribesman, ex-PC790,' pennant PE303, 'acquired from Honduras,' laid 2.1943, launched 22.3.1943, completed 3.1944 // Cuban service 1956. The fuller narrative secondary account (Wikipedia's PC-461-class article, citing De La Pedraja 1982, pp. 92, 100-101 - unretrieved print source) describes the by-then semi-derelict Baire deployed as a picket off the Isle of Pines on 17 April 1961, attacked by two Brigade 2506 A-26 Invader aircraft, badly damaged with dead and wounded crew, towed to port, and sunk dockside.

- Population
- Cuban Revolutionary Navy crew at time of loss (casualties reported in the secondary account, unquantified)
- Limitations
- Navypedia is a volunteer-compiled secondary reference; 'abortive coup' is its wording for the Bay of Pigs. Its 'PE303' pennant conflicts with PE 203 in NavSource, Jane's 1960-61, and the yard table - treated as a Navypedia transcription error, flagged in gaps. The Wikipedia narrative detail (A-26 attack, Brigade 2506, dockside sinking) is tertiary and rests partly on an unretrieved print source; the dated sinking itself (17 April 1961, Isle of Pines dockside) is consistent across Navypedia and Wikipedia. This row corrects the imprecise 'lost during the Cuban revolution' wording of NavSource/Colton toward the dated event.

[8]Era inference built on: NavSource specifications block for this hull (PC-461 class, steel hull, twin H-O-R RB-99DA diesels, no steam plant); PC-461-class design data (the wartime-standard 173-foot steel-hulled diesel sub chasers built 1941-44, more than 340 units - class counts vary by source); GAO HRD-80-2 program-level finding (see ev-uss-pc-790-pc790-08).

- Finding type
- asbestos_application
- Finding
- A steel-hulled diesel-powered patrol craft 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 and diesel-exhaust lagging in machinery spaces, gaskets, valve packing, and electrical insulation. She carried no boilers or steam plant, so the boiler/turbine lagging pathway of steam vessels does not apply.

- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire U.S. construction (1943-44) and service era (1944-46).

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming PC-790 was found in the public sources searched. No DANFS entry exists for this hull. The official USN WWII chronology carries no PC-790 entries in the 1943-1946 chapters. The CourtListener exact-name opinion query "USS PC-790" returned zero results; the other three required base queries stayed fleet-pacing-blocked through spaced retries across the session (logged 'blocked', not as negative results). Live-web sweeps surfaced only name collisions - no ship-specific asbestos content of any kind, including no law-firm marketing page for this hull.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard. If any CourtListener base query remained blocked by the fleet pacing limiter at session end, the litigation sweep is incomplete and is not treated as a negative result - see ledger. Deck logs (SL44 coverage located), the 1948 disposal instrument, Honduran-registry records, and the De La Pedraja print source are undigitized/unretrieved leads. Does not establish or defeat any claim of exposure or legal eligibility.
