- Limitations
- NavSource is a volunteer-maintained archival photo/history site drawing on official Navy records; it is the standard repository for numbered small craft lacking DANFS entries. Documents construction, service dates, and transfer; contains no materials or asbestos information. Spec figures differ from the class design table (see ev-uss-pc-770-pc770-09); commission date 31 Dec 1942 conflicts by one day with the NHHC bio summary's 1 Jan 1943 (see gaps).

- NHHC-hosted biography of Lt. Cmdr. John F. Floberg states he 'proceeded in December to the Seabrook Yacht Corporation, of Seabrook, Texas, where he assisted in fitting out the USS SC-770. He went aboard that submarine chaser upon her commissioning on January 1, 1943, and was in command from March 27, 1943 until December 1943. Under his command, the SC-770 participated in the Tunisian operations, Sicilian occupation, and Salerno landings.'

- First-person oral history by the officer who served aboard this hull from commissioning through December 1943 (exec, then commanding officer): fitting out at Seabrook; commissioning 'on New Year's Eve of 1942' ('it was 1942. I think it was New Year's Eve, it was right between Christmas and New Year's'); New Orleans for guns and ammunition; Key West anti-submarine patrols; S-1 radar installed at Miami, where he relieved the commanding officer; the Miami-Norfolk passage through an Atlantic hurricane that flooded the forward compartment; Norfolk Navy Yard repairs (ship lifted out on a derrick); a ~96-ship convoy via Bermuda to Oran; escorting six LCTs toward Cape Bon; a German air raid at Algiers; Sicily invasion arrival 9 July 1943 with wave-commander duty, harbor reconnaissance, mine-sinking by gunfire, Agrigento patrol, and Palermo harbor patrols; then British-controlled convoy work to Tripoli, Taranto, and Bari; departed the ship about 21 December 1943.

Commissioning memory 'New Year's Eve of 1942' supports 31 Dec 1942; the package's own bio summary prints 'January 1, 1943' - discrepancy carried in gaps.

- Finding
- SC-770's own signed action report for the Anzio-Nettuno operation, reviewed from the scanned original: the ship was fitted 'with a special Mark V sweeping gear made up wholly of captured German material'; 'All depth charges and a greater part of the ship's ammunition were removed in order to lighten the ship for her job in the operation.' Attached to Task Unit 81.7.2 (ComMineDiv 17, USS AM-117) of TG 81.7 (ComMineRon 8, USS AM-104), TF 81 (RADM Lowry, USS Biscayne). Narrative: streamed a ~175-yard skim sweep ahead of the invasion formation 21-22 January; cut one German mine; led HMS LST-425 and LSTs 33/404/405 into Anzio harbor; sank floating mines in fire-support areas; on 24 January her number-four 20mm gun shot down a Ju-88 during an 8-10 bomber attack (USS AM-107 near-missed by a radio-controlled bomb); on 26 January another two-engined bomber strafed the ship at ~60 feet and crashed in flames ~200 yards ahead after her fire - two bullets entered the engine room, damaging 'oil line to starboard engine, bridge controls to engine room, fresh water pump, tank and water lines, and the degaussing cable,' with no casualties. Report signed by Lt. R. E. Belknap Jr., USNR, Commanding Officer.

- Official-citation transcription names this hull: Belknap received the Silver Star 'for conspicuous gallantry and intrepidity as Commanding Officer, U.S.S. SC-770 during the advanced landings in the Anzio-Nettuno area, Italy, January 1944' - on 22 January he 'led the sweeping formations through dangerous enemy minefields and cleared beach approach lanes well inshore for the passage of the assault boat waves'; on the following night 'he led another sweep formation to within one hundred yards of the mole at Anzio'; on 24 January 'his craft participated in the effective sweeping of a fire support area close to the hostile shore' under shelling and bomber attack. Independently corroborates the NARA action report's narrative and the CO's signature.

[12]Class/era design inference from verified propulsion and construction data (NavSource hull specs; Ships of the U.S. Navy class table; PCSA class page): 110-ft wooden hull, twin GM 8-268A diesel engines, no steam plant [other_primary]
- Locator
- Derived from ev-01, ev-08, ev-09 design data
- Finding type
- asbestos_application
- Finding
- Era-consistent inference only: WWII-era diesel craft of this type could carry asbestos in exhaust-system lagging and gaskets, machinery packing, electrical insulation, deck coverings, and sundry fittings. The wooden hull and absence of boilers or steam lines remove the dominant asbestos applications documented on steam-propelled vessels of the era (boiler insulation, turbine lagging, steam-line covering), so the plausible residual footprint is materially smaller than that of a steam ship of the same era.

CourtListener base queries for both designations returned only docket-number/token collisions (Kentucky and Alabama 'SC-770' docket strings; Indiana 'PC-770' post-conviction docket; 'PC' professional-corporation + '770' address fragments) - no opinion or docket names the vessel, and the asbestos-qualified docket variant returned only token collisions inside unrelated mass-tort dockets.
