- Finding
- NavSource's live PC-1197 hull page identifies PC-1197 as a PC-461-class submarine chaser, call sign Nan-Queen-Fox-Oboe. It states that Consolidated Shipbuilding Corp. at Morris Heights, NY laid the vessel down 19 September 1942; launched it 14 November 1942; commissioned USS PC-1197 on 22 April 1943; decommissioned it 11 January 1946; struck it from the Naval Register 19 June 1946; and transferred it to the War Shipping Administration 21 June 1948, sold, with fate unknown. The page gives 450-ton displacement, 173 feet 8 inches length, 23-foot beam, 10 feet 10 inches draft, 20.2-knot speed, complement 65, armament of one 3"/50 dual-purpose mount, one 40mm mount, five 20mm guns, two rocket launchers and two depth-charge tracks, and two 1,440 bhp Hooven-Owen-Rentschler R-99DA diesel engines (serial numbers 6983 and 6984) with Westinghouse single-reduction gear driving two shafts. It states that no DANFS history is currently available for PC-1197.

- NavSource is a volunteer naval-history photo/archive compilation rather than a Navy material record; its milestone dates are carried as reported. It does not document asbestos, asbestos-containing products, crew exposure, repair scope, wartime employment, or the post-sale disposition. Its 'fate unknown' note is consistent with the MARAD database negative in ev-09.

- Finding
- The National Archives asbestos-research guide identifies Record Group 19 and RG 38 sources relevant to pre-1961 Navy-vessel asbestos research, including RG 19 Entry P 12 'Patrol Craft General Information Books [Item S-68], 1902-1955', RG 38 Entry P 1-E 'Patrol Craft Material Inspection Reports and Related Documentation, 1940-1978', ship and machinery specifications, and S39 insulation-and-lagging drawings within the Hull Series of ship engineering drawings arranged by hull number. The guide states that asbestos use in U.S. Navy materiel from 1941-1961 is a frequently requested research topic. These records are archival leads for possible hull-level material documentation, not evidence that asbestos was aboard PC-1197.

- Finding type
- asbestos_application
- Finding
- A steel-hulled patrol craft built 1942-43 at a wartime U.S. yard sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small diesel combatant of this type and period were thermal insulation and machinery/exhaust lagging in engineering spaces, gaskets and valve packing throughout the piping plant, and electrical insulation - in the confined hull volume characteristic of a 173-foot patrol craft. As a diesel-driven vessel she carried no boilers or steam turbines - the boiler/turbine lagging pathway of steam vessels does not apply.

- Finding
- A Library of Virginia World War II Navy separation notice (NAVPERS-553), transcribed through the Library of Virginia's Making History program on FromThePage, records Fireman 2nd Class Lewis Jones Caudle Jr., USNR (born 1927-06-20, Richmond, VA; enlisted 18 May 1945), as having served aboard USS PC-1197 before USS Carpellotti (APD-136); the form records 'Foreign and/or Sea Service: Yes' and names Lt. Comdr. R. W. Royston, USNR, as commanding officer at his 19 August 1946 separation at USN Personnel Separation Center, Shelton, Virginia. This places enlisted crew, including a fireman (engineering-space rating), aboard this hull in 1945-46.

It names the hull and establishes one enlisted man's service aboard during 1945-46 with foreign/sea service flagged; it does not identify a theater, establish asbestos presence or exposure, or speak to any other crew member.

- Finding
- The U.S. Maritime Administration's Vessel History Database returns no record for 'PC-1197', 'PC 1197', or '1197' in live searches run this date. NavSource records the hull as transferred to the War Shipping Administration and sold 21 June 1948 with fate unknown; the MARAD database negative is consistent with immediate post-transfer commercial sale leaving no digitized MARAD custody trail.

- Finding type

- Finding
- No qualifying ship-specific asbestos survey, abatement record, hazmat disclosure, product record, or completed litigation result was identified in the accessible public sources searched for USS PC-1197 and PC-1197. Web sweeps surfaced only the historical sources logged and no vessel-asbestos content. This is a negative finding about the sources reviewed, not a finding that asbestos was absent aboard the vessel.

- The absence of a located public record does not prove absence of asbestos aboard. The required authenticated CourtListener exact-name and hull-number sweep was blocked by the fleet daily-quota stand-down (~2.6 h requested wait), so no conclusion about qualifying litigation can be drawn from that unavailable search.
