- Finding
- NHHC documents this hull as converted from the civilian fishing vessel Julia Eleanor, 'a moderate-size fishing vessel ... built in 1937,' acquired by the Navy in November 1940, converted into a minesweeper, and placed in service as USS Egret (AMc-24) in June 1941; operated in the 4th Naval District and the Potomac River; reclassified IX-181 in July 1944; stricken from the Navy list in February 1946; transferred to the U.S. Maritime Commission in June 1946. The original print of NH 101964 is held in National Archives Record Group 19-LCM.

[4]NavSource Mine Warfare Vessel Photo Archive, 'Egret (IX 181) ex-Egret (AMc 24)' - internally inconsistent in-service date [other_primary]
- Locator
- NavSource AMc-24/IX-181 chronology block
- Finding type
- historical_record
- Finding
- NavSource lists 'Placed in service as USS Egret (AMc 24), 10 June 1940' while the same entry gives Navy acquisition as 5 November 1940 - the in-service date precedes the acquisition and is internally inconsistent. DANFS and the NHHC photo archive both place in-service in June 1941. The NavSource 1940 figure is rejected as a transcription error; 1941-06-10 is carried. (Re-verified live 2026-09-29: the inconsistency persists in the current entry.)

- Limitations
- Correction applies to the in-service date only. NavSource is a secondary compilation; its other figures (specs, complement, armament) remain unverified. Rejection of the 1940 date does not independently prove the 1941 date - that rests on DANFS/NHHC.

- Finding
- Secondary compilations document: built 1937 by J. L. Snow Shipyard / Snow Shipyards, Rockland, ME, as fishing vessel Julia Eleanor (official no. 235853, owner Julia Eleanor Co., per ShipbuildingHistory); acquired by the Navy 5 November 1940; struck from the Naval Register 25 February 1946; sold 1946 to Manuel C. DeMello of New Bedford, MA, renamed Jacintha; registered 1948 to Joseph Campanelli of San Francisco as Stera; acquired 1958 by Sofus Mortensen of Fairhaven, MA; sank in collision with the trawler Swallow on 30 May 1959 about 10 miles off Boston, MA. Listed specifications: 110 t displacement; 90'2" x 20' x 10'; 8.7 kts; complement 17; one 20mm mount and two .30 cal machine guns; one 300-shp Cooper Bessemer diesel, single shaft.

- Navy crew (~17 per NavSource, unverified); post-Navy fishing crews (1946-1959)
- Limitations
- Both are secondary compilations. They corroborate each other on builder, build year, tonnage, and length, but ShipbuildingHistory conflicts with DANFS on disposal timing ('to USN 1941' / 'sold 1945 as Jacintha' vs the documented Maritime Commission transfer of 17 June 1946). Specifications, complement, and armament figures are not verified against official records. No asbestos or material content.

[6]Fleischer WE, Viles FJ Jr, Gade RL, Drinker P, 'A Health Survey of Pipe Covering Operations in Constructing Naval Vessels,' Journal of Industrial Hygiene and Toxicology 1946 Jan;28:9-16 (PMID 21016030) - U.S. Navy health survey documenting amosite asbestos felt as 'an important ingredient of pipe covering material used on U.S. Navy vessels' [other_primary]

- Finding type
- gov_survey
- Finding
- Era context only: a wartime U.S. Navy survey documented asbestos-containing felt and pipe covering as standard insulation practice aboard naval vessels under construction - establishing that asbestos use was era-typical for a 1940-41 Navy conversion. For this hull the inference is narrow: NavSource lists diesel propulsion (one 300-shp Cooper Bessemer, single shaft) with no boilers or steam plant, so the steam-system insulation that concentrated asbestos aboard larger hulls was absent; plausible period applications would be limited to exhaust lagging, gaskets, packing, electrical insulation, and brake linings.

- Conversion-yard trades (1940-41); crew (1941-1946)
- Limitations
- Era-level epidemiology, not a hull record - the survey examined pipe covering operations at Navy and contract yards and names no individual vessel. Does not establish that asbestos was installed aboard this hull; equally, diesel propulsion does not prove asbestos absence. No quantities, no product identification, no exposure findings for this vessel.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum record, or docketed case naming USS Egret (AMc-24/IX-181) was found in the sources searched (swept 2026-09-23 under batch 1559; sources re-verified 2026-09-29 under batch 4743). CourtListener returned only name collisions - businesses, addresses, and small boats named 'Egret' (see ev-uss-egret-ix181-07 and search_ledger). MARAD's Vessel History Database indexes no vessel status card under EGRET, JACINTHA, STERA, or JULIA ELEANOR (prefix lists re-verified 2026-09-29).

- Sweep conducted 2026-09-23 under batch 1559; a 2026-09-29 re-run was attempted twice and blocked by the fleet-wide CourtListener pacing budget (hourly cap, not daily exhaustion) - the 6-day-old sweep is carried and dated honestly. CourtListener coverage is not exhaustive of all state/federal dockets; absence here does not prove no suit was ever filed.
