- Limitations
- NavSource is a volunteer secondary compilation - its milestone dates track DANFS/NVR but it is not a primary registry. 'Fate unknown' means no public disposition record located after the 1963 USAF transfer. The 'plan for decommissioning ... as January 1947' note refers to the reserve program as transcribed in the 1949 NVR - she actually decommissioned July 1946. No asbestos content.

- Finding type
- asbestos_application
- Finding
- A 450-ton diesel-drive submarine chaser built 1941-42 at a wartime emergency yard sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small combatant of this type and period were engine exhaust lagging, thermal insulation around hot machinery and piping, gaskets, valve packing, and electrical insulation in a confined hull volume. As a diesel-drive craft she carried no boilers or turbines - the boiler/turbine lagging pathway of steam vessels does not apply, but small-craft confined-space and engine-room exposure dynamics apply.

[6]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct 18, 1979) - product page Highlights (verified live via firecrawl 2026-10-03) [gao]

- GAO product page HRD-80-2, Highlights section
- Finding type
- gov_survey
- Finding
- GAO reviewed 'the Navy's efforts to protect workers from asbestos exposure at the Long Beach and Norfolk Naval Shipyards,' including 'the use of asbestos in Navy ships, the cost of removing asbestos from Navy ships, and compensation programs for asbestos-related disabilities.' The Navy's 1975 policy was 'to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed to accomplish necessary repairs,' modified in 1979 to include selectively replacing asbestos insulation in high-maintenance areas - program documentation that asbestos insulation was carried aboard Navy ships through and past this hull's construction (1941-42) and service era (1942-46).

- Finding
- Builder-yard documentation covering this hull's construction environment: Brown Shipbuilding was established 1941 by George and Herman Brown of Brown and Root; the Navy's original four-submarine-chaser contract went to Platzer Shipbuilding and George Brown transferred the Platzer contracts to the new Brown Shipbuilding Company in August 1941; the yard occupied narrow Greens Bayou off the Houston Ship Channel and launched vessels sideways; employment exceeded 25,000 workers from late 1942; Brown built 12 PC-461-class submarine chasers, 61 destroyer escorts (38 Edsall- and 23 John C. Butler-class), 32 LCIs, and 254 LSMs, and received the Army-Navy 'E' production award in December 1942. Postwar: 'In 1949 the Brown shipyard was leased to the Todd Shipyards Corporation as a ship repair facility. In 1984, Brown and Root took over the shipyard for use as an offshore fabrication yard. In 2004 it was gradually sold off to what is now known as the Brown Shipbuilding Industrial Park.'

[8]NavSource Online, Altus (PC 568) ex-PC-568 - sister hull's parallel USAF chain (verified live 2026-10-03) [other_primary]
- Locator
- NavSource 12/010568.htm header block
- Finding type
- vessel_history
- Finding
- The only other PC loaned to the Air Force followed the identical chain and a documented disposition: PC-568 (Altus) was loaned to the USAF in 1960, struck and permanently transferred to the Air Force 15 March 1963 (same date as Riverhead), then transferred to the Philippines 2 March 1968 and renamed Nueva Viscaya (PS-80); sank during a typhoon at Cebu; sold as scrap to Calixto Enterprises, Philippines. The parallel chain shows the USAF loans were genuine transfers of custody and onward disposal was possible - but no corresponding onward record is located for PC-567.

- Limitations
- Sister-hull record cited as context for what the USAF-to-disposal chain looked like in the documented case; it does NOT establish PC-567's fate - hers remains 'unknown' per NavSource. Sister-hull sinking date varies across secondary sources (NavSource 10 March 1993 typhoon; Wikipedia class article 12 November 1990, Typhoon Mike) - not material to this hull. NavSource/DANFS label these hulls PC-542 while uboat.net and Wikipedia group them under PC-461 - a class-labeling nuance, carried in gaps.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS PC-567 / USS Riverhead was found in the public sources searched. CourtListener was PARTIALLY searched this session: the exact-name opinion query ('USS Riverhead', type=o, 2026-10-03) returned 2 results, both memorandum opinions in United States v. Bertelsmann SE & Co. KGaA (D.D.C., No. 2021-2886) where 'Riverhead' refers to the Penguin Random House imprint Riverhead Books - name collisions, not vessel references. The exact-name docket, hull-number opinion, and hull-number docket base queries could not be completed: the fleet-wide pacing budget was intermittently spent across the session - logged as blocked in search_ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case; PC-567 does not even appear in the law-firm marketing ship lists surfaced this session (the marketing coverage found is builder-level only: mesothelioma.com, mesotheliomalawyercenter.org, mesothelioma.net pages on Brown Shipbuilding - excluded by source policy).

- Absence of a located public record does not prove absence of asbestos aboard - and three of four required CourtListener base queries remain genuinely open (blocked by fleet pacing, not run to completion). Deck logs (NARA RG 24), Brown Shipbuilding work packages, and any USAF disposal records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
