- NavSource timeline for this hull: PC-461-class submarine chaser; laid down 12 December 1942 by Sullivan Dry Dock and Repair Co., Brooklyn, NY; launched 3 April 1943; delivered 19 June 1943 and commissioned USS PC-1234; transferred to Uruguay 2 May 1944 and named ARO Maldanado [sic - see ev-12] (PC 1); reclassified B-1; 'Returned to U.S. Navy in April 1948 and transferred to the State Department, Foreign Liquidation Commission. Fate unknown.' Call sign Nan-Charlie-Mike-Oboe. Specifications: 280 t. light / 450 t. full load; length 173'8"; beam 23'; draft 10'10"; speed 20.2 kts; complement 65; armament one 3"/50 dual-purpose mount, one 40mm, three 20mm, two rocket launchers, four depth charge projectors, two depth charge tracks; propulsion two 1,440 bhp Fairbanks Morse 38D8-1/8 diesel engines, Westinghouse single reduction gear, two shafts. Photographs show the hull in Uruguayan service as PC-1 and (c. 1953) as B-1 (Uruguayan Navy photo).

Contains no asbestos content. The 'Returned to U.S. Navy in April 1948' line describes the administrative title return preceding the FLC surplus sale, not a physical return - the hull demonstrably remained in Uruguayan service until 1970 (ev-06, ev-07). 'Fate unknown' is superseded by Uruguayan-side sources (ev-07).

- Finding
- Builder documentation for this hull: Fred Sullivan leased the repair yard at the head of Brooklyn's Tebo Yacht Basin (foot of 22nd, 23rd and 24th Streets) from Todd Shipyards in 1937, renamed it Sullivan Dry Dock & Repair Co., converted it to new construction, and it closed in 1947. The production list records fifteen-plus PC-461-class subchasers built for the US Navy; the PC-1234 row reads 280 LDT / 174 ft, delivered 19 June 1943, 'to Uruguay 1943 as Maldonado (PC-1)' - corroborating builder, delivery date (19 June), Uruguayan name, and pennant; the '1943' transfer year is a compilation slip against the documented 2 May 1944 handover (ev-01, ev-06, ev-07).

- Finding type
- historical_record
- Finding
- Primary US diplomatic record resolving this hull's post-US disposition: in May 1947 the US Embassy Montevideo reported plans 'of US Navy to offer four ships for sale as surplus property at low price' - aircraft rescue vessel, motor launch, picketboat, and 'the subchaser' (this hull, the sole US subchaser leased to Uruguay under the wartime Naval Lease Agreement). The Uruguayan Navy Inspector General 'claims subchaser does not meet Uruguay's requirements' and would 'retain subchaser only until replaced by destroyer,' with purchase financing 'partly based on credit which will accrue ... when subchaser returned.' In December 1947 Washington advised that OFLC 'expects to offer to Uruguay ... the U.S. naval vessels leased to Uruguay under the Naval Lease Agreement'; Uruguay 'will not be charged for use of vessels, as contemplated in Article VI'; 'total cost of vessels to U.S. was $1,323,883, they will be offered to Uruguay at total price of $35,361'; and 'sale of ships individually would be unfeasible, price quoted presupposes all will be purchased and none returned to U.S.' This documents the administrative mechanism behind NavSource's 'Returned to U.S. Navy in April 1948 and transferred to the State Department, Foreign Liquidation Commission' - a title transfer for surplus disposal, not a physical return; the hull stayed in Uruguayan service.

- Uruguayan-service record for this hull: transferred to Uruguay at Miami 1 May 1944 after service under USN flag; arrived Montevideo 31 July 1944; officially classified as corvette ('Corbeta Antisubmarina' B-1 per Uruguayan accounts); stricken November 1970 ('11.1970'; Uruguayan naval-history accounts give the baja as 21 November 1970, when she was replaced by the incoming Agile-class minesweeper ex-USS MSO-451 which took the name ROU MS-33 Maldonado). Uruguayan accounts further record her as the first modern vessel transferred to the Armada under Lend-Lease, handed over at Miami 1 May 1944 to a delegation under T/N Manuel de La Bandera, exercising with escorts ROU Uruguay and ROU Artigas from 1952, and participating in the first UNITAS exercises November 1960. navypedia specifications in Uruguayan service: 280 t standard / 330 t full; 51.8 m wl / 52.9 m oa; 2 diesels 2,880 hp; 21 kts; complement 65; 1953 photograph on file.

- Finding
- A steel-hulled twin-diesel patrol craft built 1942-43 at a Brooklyn commercial yard sits inside the Navy's documented asbestos-use era; era-standard applications aboard a vessel of this type and period were machinery and diesel-exhaust lagging, gaskets, valve packing, electrical insulation, and interior thermal/acoustic insulation in small enclosed spaces. As a diesel craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply.

- Finding
- GAO reviewed Navy efforts to protect workers from asbestos exposure (fieldwork at Long Beach and Norfolk Naval Shipyards), covering 'the use of asbestos in Navy ships, the cost of removing asbestos from Navy ships, and compensation programs for asbestos-related disabilities.' The Navy's 1975 policy was to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed for necessary repairs, modified in 1979 to selective replacement in high-maintenance areas - confirming extensive asbestos insulation use aboard Navy ships through the era spanning this hull's construction and service.

- CORRECTION: NavSource twice spells the Uruguayan name 'Maldanado' (header block and photo caption). Every other source - navypedia, uboat.net, the builder production list, and Uruguayan naval-history accounts - gives 'Maldonado,' matching the Uruguayan department the ship was named for (and the second Maldonado, ex-French minesweeper MS-33, that replaced her in 1970). The correct rendering is ARO/ROU Maldonado (PC-1, later B-1). NavSource's 'ARO' prefix is also non-standard; Uruguayan usage is ROU (Republica Oriental del Uruguay), though ARO (Armada Republica Oriental) appears in period documents.
