- Finding
- Documented for this hull: laid down 25 July 1942 at Consolidated Shipbuilding Corp., Morris Heights, NY; launched 19 September 1942; commissioned 8 February 1943; transferred to the War Shipping Administration 21 June 1948 and sold; 'Fate unknown.' Spec block: displacement 450 t.; length 173'8"; beam 23'; draft 10'10"; speed 20.2 kts.; complement 65. Armament: one 3"/50 dual purpose gun mount, one 40mm gun mount, five 20mm guns, two rocket launchers, two depth charge tracks. Propulsion: two 1,440bhp Hooven-Owen-Rentschler R-99DA diesel engines (Serial No. 6971 and 6972), Westinghouse single reduction gear, two shafts. Call sign: Nan - Queen - Charlie - Uncle. Photo captions document commissioning day 8 February 1943 at the New York Navy Yard, Brooklyn, NY - 'CDR H.F. Sasse, USN, Assistant Captain of the Yard acting for Captain of the Yard, representative of the Commandant, Third Naval District, addresses the crew' - plus crew and engineering-gang photographs. Page states: 'There is no DANFS History currently available for PC-1194.'

- NavSource is a volunteer secondary compilation, not a primary registry - milestone dates generally track official records but each remains uncorroborated by a primary document for this hull (no DANFS entry exists). Disposal wording 'transferred to the War Shipping Administration 21 June 1948 and sold' conflicts with the builder-yard table's 'To MARAD 1946' (see ev-02 and gaps). Contains no asbestos content.

- Finding
- Builder-yard production record for this hull: yard hull #3124, 'PC 1194', owner US Navy, type Sub Chaser, length 173 ft., delivery 8-Feb-43, disposition 'To MARAD 1946'. Yard context from the same page: Consolidated Shipbuilding resulted from the merger of Gas Engine & Power Co. and Charles L. Seabury Co.; the Morris Heights yard stood on Matthewson Road at the southern end of what is now Roberto Clemente State Park; after WWII Consolidated bought the Robert Jacob and B. F. Wood yards on City Island and closed Morris Heights; the company ceased active boatbuilding in 1958.

- Specialized secondary compilation (Colton yard tables), not a primary registry - hull-number detail is the strength of this source. 'To MARAD 1946' conflicts with NavSource's 'transferred to the War Shipping Administration 21 June 1948 and sold': the 1946 figure likely reflects post-war inactivation/custody while 1948 is the documented transfer-and-sale event - unresolved (see gaps).

Chambers's prior/next assignment per the site: subsequently commanded USS Gustafson (DE-182), 2 Mar 1944 - 22 Sep 1945.

- Finding
- Sister-hull context only. PC-1193 - laid down at the same yard (Consolidated, Morris Heights) 30 June 1942, commissioned at the New York Navy Yard 21 January 1943, eighteen days before PC-1194 - has a full DANFS entry while PC-1194 has none. Her documented pattern: assigned to Service Squadron 1, Service Force, Atlantic; departed New York 13 February 1943 for the Submarine Chaser Training Center, Miami; 'extensive patrol and escort services out of Miami, with periodic calls at Charleston, S.C., for availability' through end of hostilities; decommissioned Boston 2 March 1950; named Ridgway 1956. DANFS spec block for the sister: dp. 348; l. 174'9"; b. 23'; dr. 7'6"; s. 20.2 k.; cpl. 65.

- Class/sister-ship documentation - describes PC-1193's service, NOT PC-1194's. PC-1194's own operating area and assignments are undocumented in public sources (see gaps); the sister's Miami/Atlantic pattern is a plausible-but-unproven parallel for a same-yard, same-period hull. The sister's spec block corroborates class-level parameters (20.2 kts, cpl. 65). No asbestos content.

[7]Era inference built on: NavSource propulsion spec for this hull (2 x 1,440bhp Hooven-Owen-Rentschler R-99DA diesels, Westinghouse single reduction gear, 2 shafts); HyperWar PC-461-class spec block; GAO HRD-80-2 Navy asbestos-era documentation (see ev-07); NARA asbestos-research pathway (see ev-06) [other_primary]

- Finding type
- asbestos_application
- Finding
- A steel-hulled diesel patrol craft built 1942-43 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small diesel combatant of this period were diesel exhaust insulation, machinery and piping lagging, gaskets, valve packing, and electrical insulation within the confined 173-foot hull. As a diesel vessel she carried no steam plant - the boiler/turbine lagging pathway of steam ships does not apply.

- NARA documents the official avenue for ship-specific asbestos research: Record Group 19 (Bureau of Ships) general/confidential/secret correspondence 1940-1961 filed by hull designation and filing code (e.g., hull-specific files under the vessel's designation, class correspondence under the class namesake's filing code, shipyard correspondence under QM/<yard name> for private builders like Consolidated), plus General Information Books by vessel type. Acknowledges the period '1941-1961' as the documented asbestos-in-materiel window - which covers this hull's entire construction and service life. Also points to deck-log and war-diary series for individual ship histories.

- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire construction (1942-43) and service era (1943-46) and disposal (1948).

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming PC-1194 was found in the public sources searched. CAVEATS: (1) CourtListener could not be queried this session - API returned HTTP 429 (daily quota exhausted, ~2.7 h to reset) and is logged as blocked in search_ledger, not as a negative result. (2) Secondary web sweeps surfaced only law-firm marketing content: navyshipexposure.com publishes a 'PC-461 Class' asbestos page asserting asbestos-containing gaskets/insulation without primary sourcing (and misstates the class propulsion - see ev-10); levylaw.com and asbestos-ships.com publish Consolidated Shipbuilding asbestos-jobsite pages. All excluded by source policy. (3) PC-1194 does not appear in the PCSA casualty/damage roster - consistent with surviving the war intact.

- Absence of a located public record does not prove absence of asbestos aboard - and the litigation repository search is a genuine open gap (throttled, not run). RG 19 BuShips hull and QM/Consolidated correspondence files, deck logs (RG 24), and war diaries (RG 38) are undigitized leads. MARAD's vessel status card for the 1948 sale may exist but the database search could not be completed via static fetch. Does not establish or defeat any claim of exposure or legal eligibility.

- Finding type

- Finding
- CORRECTION: navyshipexposure.com's PC-461-class page states 'PC class vessels were powered by four General Motors diesel engines' - factually wrong for this class and this hull: documented propulsion for PC-1194 is two 1,440bhp Hooven-Owen-Rentschler R-99DA diesels (serial numbers published), and the class spec is two diesel engines on two shafts (HyperWar official-source block; NavSource). The page's asbestos product assertions are unsourced and excluded under the banned-source policy; the propulsion error is carried here to document why this source cannot anchor any product list.
