- Finding
- SC-697 appears in the SC-497-class listing with commission window 1942-44 and the note 'Lend-Lease to France.' The page's SC-497 class block gives: displacement 98 tons, length 110'10", beam 17', draft 6'6", speed 20 knots, armament 1 3"/50 and 2x2 .50-cal. mg, complement 2 officers + 20 enlisted, diesel engines, twin screws, 1,200 shaft hp.

- HyperWar is a transcription project compiled from U.S. Navy sources; the entry confirms the Lend-Lease disposition but the class-block figures conflict with NavSource on displacement (98 vs 148 t.), speed (20 vs 15.6 kts.), complement (22 vs 28), and power (1,200 shp vs 2x880 bhp) - conflicts logged in gaps, not resolved.

- Builder's delivery table: SC 697, US Navy sub chaser, 136 LDT, 110 ft, delivered 24 December 1942, disposition 'To Free French 1944 as CH 92.' The same table documents the yard's other SC-497-class boats, including sisters SC-694 and SC-696 (bombed and sunk off Palermo 23 August 1943) and SC-695 (to Free French 1944 as CH 133), establishing the yard's build run around this hull.

The 9 July 1958 decommissioning date and the CH 701 / P 701 renamings rest on this source alone and conflict with NavSource's 'fate unknown'; carried as an archival lead pending corroboration from Service historique de la Defense or alamer.fr.

[6]NavSource Online: Submarine Chaser Photo Archive, SC-697 (12/150697) - designation history; batch re-scope per fleet fact-QA (crew signs 924-929, 2026-09-29) [other_primary]
- Locator
- NavSource page header ('ex-PC-697') and timeline; batch8071 prompt QA note
- Finding type
- vessel_history
- Finding
- Designation correction: this hull was never a PC-461-class steel patrol craft. Fleet fact-QA (2026-09-29) confirmed the PC-461 enumeration is closed (341 completed + 60 cancelled; PC-679-720 in neither list), so 'PC-697' never denoted a PC vessel. NavSource records the wooden SC-497-class hull commissioned as USS PC-697 on 24 December 1942 and reclassified SC-697 in April 1943 - a brief paper designation on a submarine-chaser hull, not a separate ship. The record is filed under SC-697 accordingly.

- Limitations
- Corrects cataloging only; the PC-697 commissioning designation is documented by NavSource, but the closed-enumeration finding comes from the batch's QA note rather than a cited primary enumeration - the underlying PC-461 build/cancel lists were not re-verified this session. Contains no asbestos information.

- HyperWar SC-497 class block; NavSource SC-697 specifications (two GM 8-268A diesels, two shafts)
- Finding type
- asbestos_application
- Finding
- The SC-497 class is a 110-foot wooden-hulled, diesel-powered submarine chaser with no boilers or steam plant. The steam-system lagging pathway (boiler insulation, steam-line covering, turbine lagging) that drives asbestos documentation on larger combatants does not exist on this type. Era-standard asbestos-containing applications aboard a 1942 diesel small combatant would be limited to machinery gaskets, exhaust-system lagging, and electrical insulation.

- Limitations
- Class/design-level inference only - no source documents any asbestos-containing material aboard this hull, and the wooden diesel design bounds (but does not eliminate) the plausible applications. Does not establish presence, quantity, condition, or any individual exposure.
