- Limitations
- NavSource is a volunteer-maintained photographic and records archive, not an official Navy publication; its per-hull tables are compiled from official lists and veteran submissions and are the standard reference for numbered small craft that lack DANFS entries. Contains no asbestos information. Armament/speed figures differ from class-generic tables (see gaps).

- Locator
- SC-497 class record (Displacement 98 t, 110'10", diesel engines twin screws 1,200 shaft hp)
- Finding type
- asbestos_application
- Finding
- The SC-497 class is documented as a wooden-hulled 110-foot diesel submarine chaser type - no boilers and no steam plant aboard. On a wooden diesel craft of 1942 the era-consistent asbestos applications were limited to non-steam machinery items: diesel exhaust lagging, machinery gaskets and packing, and electrical insulation, if present at all.

- Population
- Construction trades at small boat yards (Daytona Beach Boat Works, 1942); engine-room crew
- Limitations
- Class/design context, not a hull record - the source documents the type as wooden-hulled and diesel-powered but names no asbestos product; the listed applications are era inference for a diesel craft, not ship-proven items. Does not establish that asbestos was or was not present aboard SC-694, nor in what quantity or condition.

[5]GAO HRD-80-2, review of Navy efforts to protect workers from asbestos exposure at Long Beach and Norfolk Naval Shipyards (published 1979-10-18, released 1979-10-22) [gao]

- GAO product page HRD-80-2, Highlights section
- Finding type
- gov_survey
- Finding
- GAO reviewed the Navy's use of asbestos insulation in ships, the cost of removal, and compensation programs; the product page documents that asbestos insulation was in service across the fleet and that the Navy's 1975 policy was remove-and-replace only when damaged, modified in 1979 to selective replacement in high-maintenance areas.

- Limitations
- Program-level context only - the review centered on steam-era insulation and post-war shipyard abatement at two named yards; it does not address wooden diesel subchasers, a hull sunk in 1943, or any vessel of this class by name. Product-page description used; does not establish asbestos aboard SC-694.

[6]Batch-8068 search ledger (this record): NavSource SC-694 page (states no DANFS history available); NHHC ship-histories index and HyperWar DANFS mirror (no SC-694 entry); CourtListener opinion and docket searches for 'SC-694' and 'PC-694' (three of four base queries completed - all hits were docket-number/name collisions; 'PC-694' opinion query blocked by fleet pacing); NARA deck-logs portal; shipyards.json yard dataset [other_primary]

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located: no DANFS entry exists for this hull (NavSource states it; NHHC and HyperWar searches concur), and no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming SC-694 or PC-694 was found in the public sources searched. CourtListener returned only docket-number/name collisions in the three completed base queries; the fourth ('PC-694' opinion) never reached the API (see search_ledger).

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - 1942 construction-era materials on a diesel craft were simply never documented for this hull. The vessel was sunk in 1943, so no post-war survey or abatement record could ever exist. Does not establish or defeat any claim of exposure or legal eligibility.

[7]National Archives, 'Navy Deck Logs Available in the National Archives Catalog' portal - deck logs of commissioned vessels held as permanent records, WWII-era logs largely digitized [other_primary]
- Locator
- archives.gov deck-logs portal; catalog.archives.gov search did not surface a hull-specific entry
- Finding type
- historical_record
- Finding
- SC-694 was a commissioned vessel (September 1942 - August 1943); her deck logs for that window, the ship's war diary if any, and any surviving loss/action reports would be the primary ship-specific record set. NARA holds commissioned-vessel deck logs as permanent records and has digitized the WWII-era run; a hull-specific catalog entry was not located in this session's search.

[8]NavSource Online 110' Submarine Chaser (SC) Photo Index - index entries mark numerous SC hulls 'ex-PC-###', confirming a block of PC designations carried by SC-497-class boats [other_primary]
- Locator
- NavSource SC-694 page; SC index ex-PC markings
- Finding type
- historical_record
- Finding
- SC-694 was commissioned under the designation PC-694 (September 1942) and reclassified SC-694 in April 1943; the same ex-PC pattern appears across the SC index (PC-498, PC-503, PC-504, PC-639, PC-642, PC-643, PC-667, and others). The hull was never a PC-461-class steel-hulled patrol craft - the PC designation block was carried administratively by 110-foot wooden SC-497-class boats pending reclassification.

- Limitations
- Corrects an identity confusion: 'PC-694' appears in records but denotes this wooden subchaser, not a PC-461-class patrol vessel (that class's enumeration does not include PC-694). NavSource documents the commissioning designation; the precise date in April 1943 of the reclassification order is not stated.
