- Limitations
- DANFS documents construction milestones and disposition only - no service narrative, no materials or asbestos content, no decommissioning or striking date. DANFS does not state the commissioning designation (PC-769 vs SC-769); the PC-769 commissioning designation and April 1943 reclassification rest on NavSource.

- Finding
- DANFS documents this hull operating in the Pacific in April 1945: on 6 April 1945 the gasoline tanker Narraguagas (AOG-32) sailed for Eniwetok as part of Task Unit 16.8.1 comprising Kanawha (AOG-31), fuel barge YO-173, Narraguagas, 'and two submarine chasers, SC-769 and SC-994'; the task unit hove-to off Johnston Island 10-11 April while Narraguagas discharged cargo, and Narraguagas anchored at Eniwetok on 20 April 1945. Places this hull on forward Pacific convoy-escort duty in spring 1945.

Its 'October 1947' Philippine transfer date conflicts with DANFS (7/2/48) and with the builder-yard list ('1948'); DANFS date carried. Specifications are class-standard figures, not a survey of this specific hull. No asbestos or materials information.

The roll's start date equals the DANFS commissioning date and its 1946 end date marks the close of US Navy manning - corroborating continuous documented US Navy service from commissioning through 31 May 1946.

- Finding
- CORRECTION of a catalog presumption: this hull is a 110-foot wooden SC-497-class submarine chaser, not a PC-461-class 173-foot steel patrol craft. It carried the patrol-craft designation PC-769 only at commissioning (5 December 1942) until the class-wide reclassification of the 110-footers to SC numbers in April 1943. Treating PC-769 as a PC-461-class hull would attach the wrong hull type, dimensions, and propulsion to this vessel.

- Finding type
- asbestos_application
- Finding
- A 110-foot wooden-hulled submarine chaser built in 1942 with twin diesel propulsion sits inside the Navy's documented asbestos-use era; era-standard small-craft applications - engine and exhaust/muffler lagging, machinery-room thermal insulation, gaskets, valve packing, electrical insulation, and deck coverings - are consistent with the class design but are INFERRED, not documented aboard this specific hull. The wooden hull and absence of a steam plant narrow the plausible application set relative to steam-driven steel ships: no boiler or steam-pipe lagging pathway exists.

- Finding type
- gov_survey
- Finding
- Program-level context: GAO reviewed Navy efforts to protect workers from asbestos exposure at Long Beach and Norfolk Naval Shipyards; per the product-page summary, 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 selectively replace asbestos insulation in high-maintenance areas. Documents that asbestos insulation was a fleet-wide shipbuilding/repair material in this hull's era.
