- DANFS numerical summary for this hull: 'Eagle No. 46 - Keel laid 2/24/19. Launched 5/24/19. Commissioned 10/3/19. Classified as PE-46 7/17/20. Sold 12/10/36.' Class record: Eagle boats were Navy steel anti-submarine patrol craft mass-produced by Ford Motor Co. at a purpose-built Rouge River plant, Detroit; ordered Jan 1918 (100, later 112 incl. 12 for Italy), cut to 60 after the Armistice; seven commissioned 1918, the remaining 53 in 1919; machinery/fittings largely built at Ford's Highland Park plant; the boats never saw WWI service; in the early postwar years a number were used as aircraft tenders (photographic reconnaissance planes at Midway 1920, Hawaiian Islands 1921), a number transferred to the Coast Guard in late 1919, and the balance sold in the 1930s and early 1940s.

- Finding
- NavSource timeline for this hull: laid down 24 February 1919 by Ford Motor Co., Detroit, MI; launched 24 May 1919; commissioned USS Eagle No. 46, 3 October 1919; designated PE-46, 17 July 1920; struck from the Navy list 18 December 1930 and transferred to the United States Shipping Board; returned to Navy custody 13 June 1932; sold 10 December 1936; 'Fate unknown.' Photo captions place this hull at the Boston Navy Yard c. 1919 (with PE-19; Boston Public Library Leslie Jones photo) and again in the early 1920s with Boston Navy Yard Floating Crane No. 35 (YD-35) (NHHC photo NH 54324). A caption naming this hull states: 'Eagle Boats PE-46 and PE-19 were among the few to remain on active duty as escort vessels for the Navy during the 1920s,' and notes the forecastle winches 'in the 1930s and during World War II ... were used to tow targets and provide salvage work.' Specifications: 710 t.; 200'9" length; 25'9" beam; 13'6" draft; 18.32 kts.; complement 68; two 4"/50 mounts and two .50 cal. machine guns; two Thorny-Croft Bureau Model 250psi boilers, one 2,500shp Poole geared turbine, Ford single reduction gear, one shaft.

- Limitations
- Volunteer secondary compilation, not a primary registry; milestone dates corroborated by DANFS and Ships' Data. The escort-duty caption names PE-46 for the 1920s role; the 1930s/WWII target-towing claim is class-level - PE-46 was struck Dec. 1930 and sold 1936, so WWII towing does not apply to this hull. No asbestos content. Boston Navy Yard photos establish presence, not work performed there.

The logs are undigitized paper records held by Archives I (Washington, DC) in RG 24 Entry 118 - the authoritative primary source for the vessel's day-to-day 1919-1930 employment, including the September 1922-April 1923 interval for which no logbook is listed.

[7]Era inference built on: DANFS class appendix general characteristics (Poole geared turbine, 2,500 SHP); Ships' Data 1929 class table (2 Bureau express oil-burning boilers, 1 Poole geared turbine); NavSource specifications (two Thorny-Croft Bureau Model 250psi boilers, one Poole geared turbine); GAO HRD-80-2 (see ev-07) [other_primary]

- Finding type
- asbestos_application
- Finding
- A steel patrol craft built 1919 with two oil-burning water-tube boilers and a geared steam turbine would have carried era-standard asbestos applications: magnesia-asbestos boiler and steam-line lagging (the standard marine steam-plant insulation of the period), flange and valve gaskets, and machinery packing - the boiler/turbine lagging pathway of a small steam vessel. GAO documented Navy-wide asbestos insulation use aboard ships through the early 1970s, spanning this hull's entire construction and service era.

Names era-standard applications, not confirmed installed materials; no quantity; no manufacturer attribution for this hull. The boiler-type attribution itself differs by source ('Bureau express' vs 'Thorny-Croft Bureau Model' - likely the same Bureau-designed express water-tube type; see gaps).

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or litigation naming USS Eagle No. 46 / PE-46 was found in the public sources searched (see search_ledger). The vessel's era (built 1919, struck 1930, sold 1936) predates the asbestos-litigation window; no opinion or docket naming this hull was located. CAVEAT: the 62-hit "PE-46" docket result set was reviewed on the first page only (all exhibit-designation collisions), and the asbestos-qualified variant query was blocked by the fleet pacer - residual hits unreviewed. Secondary web sweeps surfaced no qualifying material.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1919 steam vessel's lagging/gasket/packing suite is era-consistent with asbestos content, and the undigitized deck logs and any Shipping Board/sale records remain open archival leads. The high-collision docket result set is not fully exhausted (62 hits, page 1 reviewed; variant blocked) - residual risk of an asbestos docket among unreviewed pages is small (collision pattern is generic exhibit numbering; exact-name queries were zero on both indexes) but open. Does not establish or defeat any claim of exposure or legal eligibility.
