- Limitations
- Ship-specific historical record only; it does not document asbestos, material content, exposure, abatement, or litigation. NavSource is an archival compilation, not a current NVR record; the page's history addendum appears drawn from Coast Guard service records but the underlying document is not reproduced. The 3 September 1947 Republic of China transfer date precedes the 8 December 1947 U.S.-China transfer agreement (see ev-04); the basis for the earlier date is not stated.

- The official 1945 Ships' Data Book lists SC704 built by Elizabeth City Shipyard, Elizabeth City, N.C., keel laid 7 March 1942, launched 6 April 1942, and date of first commission 28 September 1942; the propulsion table lists SC704 with G.M. 8-268A engines, 800 shaft horsepower, S.K. (Snow & Knobstedt) reduction gear, 116 tons trial displacement, and 15.6 knots trial speed.

- Limitations
- Ship-specific specifications and milestones only; contains no asbestos, material-content, exposure, or litigation information. The book post-dates the April 1943 reclassification and so tabulates the hull under SC704; it does not itself record the PC-704 commissioning designation or the reclassification. NavSource's 880-bhp engine rating differs from this source's 800 shaft horsepower; both are stated, not harmonized.

- Limitations
- Class-level data, not a hull record: the generic 110'SC row describes the type and does not by itself establish any material aboard SC-704. No asbestos content is stated anywhere in the source. The wood-hull note limits but does not eliminate candidate asbestos applications (machinery/exhaust insulation, gaskets, packing, electrical) aboard the type.

- Finding
- Schedule 'A' of the U.S.-Republic of China naval-transfer agreement lists 'SC 704' at location 'Philippines' among the 'vessels now earmarked and recommended for transfer to China under Public Law 512, 79th Congress, 2nd Session, and provisions of Executive Order No. 9848 of April 25, 1947.' This is the treaty instrument governing SC-704's transfer to the Republic of China.

- Limitations
- Establishes the transfer instrument and the hull's Philippine location, not an execution date: NavSource gives the transfer itself as 3 September 1947 while this agreement was signed 8 December 1947 and a secondary yard record says 'To Taiwan 1948'; the exact handover date and post-transfer disposition are unresolved. Contains no asbestos, exposure, or condition information.

- Finding type
- asbestos_application
- Finding
- GAO's Navy program review describes asbestos applications aboard Navy ships at the program level - thermal insulation for machinery, equipment, and piping as the major application, plus piping-system gaskets and packing, electrical components, deck tile, and equipment brakes - and reviews asbestos-removal policy at Long Beach and Norfolk Naval Shipyards. SC-704's 1942 construction and 1942-46 Navy service fall within the historical Navy shipbuilding period this program context addresses.

- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement contract, hazmat disclosure, material specification, or qualifying asbestos litigation record naming USS SC-704 or PC-704 was located in the sources reviewed. CourtListener exact-phrase opinion searches returned six hits for 'SC-704' - all name collisions on court docket numbers and reporter citations, none vessel-related or asbestos - and zero hits for 'PC-704'. RECAP docket searches for both designations were invoked through the authenticated helper but the fleet-wide limiter reported its paced request budget temporarily spent before usable result payloads could be obtained; docket status is blocked, not a negative result. No asbestos-qualified variants were run because base-query overflow was not established.
