- Finding
- DANFS record for this hull: laid down 2 January 1943 by Dravo Corp., Wilmington, Del.; launched 8 July 1943, sponsored by Miss Louisa Rodgers Alger; commissioned at the Philadelphia Navy Yard 12 November 1943, Lt. Comdr. W. F. Porter in command; Bermuda shakedown; returned to Philadelphia for post-shakedown availability (Dec 1943-Jan 1944); Caribbean/South Atlantic convoy-escort and patrol duty (TG 42.5, TG 41.5) operating Trinidad-Recife-Natal 1944-45, incl. a minor bow collision with a merchantman en route to Recife (Feb 1944) and ASW exercises with USS Solomons (CVE-67) off Brazil (Jul 1944); relieved of operational duties 31 January 1945; decommissioned and loaned to the Brazilian Navy 10 March 1945; struck from the Navy list 20 July 1953 with title transferred outright to Brazil; served as Babitonga until discarded in 1964.

- Limitations
- DANFS documents service history and specifications, not materials or asbestos content. The DANFS narrative implies decommissioning at Natal (departed Recife 23 Feb, moored Natal same day); NavSource reads 'decommissioned at Rio De Janeiro' - carried in gaps. Mirror transcription cited because the live NHHC page returns 404.

- Finding
- Official Brazilian Navy ship sheet for this hull: ex-USS Alger DE-101, built by Dravo Corporation, Wilmington, Delaware; keel laid 2 January 1943, launched 8 July 1943; incorporated into the Marinha do Brasil 10 March 1945 (Aviso Ministerial n. 503A) at Base Naval de Natal and into the Forca Naval do Nordeste 12 March 1945 (Aviso n. 507); pennant Be7, later D16. Describes the diesel-electric machinery (GM 16-278A mains, GM 8-268A and 3-268A service diesels) and two auxiliary Cycloterm MC-90 boilers (3,000 lb steam/hr); wartime complement 13 officers/213 enlisted, 188 peacetime; 156,318 miles steamed in 19 years; decommissioned 22 July 1964 (Aviso Ministerial n. 219) and sold for scrap by the Servico de Alienacao de Bens.

- Limitations
- Official Brazilian Navy historical record - documents machinery fit, service, and disposition, not asbestos content; the auxiliary-boiler listing establishes small steam plant aboard (relevant to material categories) without stating insulation composition. DPHDM machinery figures (two 1,700-hp mains described, three-displacement table) differ from US specifications (four GM diesels, 6,000 shp) - US-figures carried for propulsion summary; no silent reconciliation.

- Finding type
- asbestos_application
- Finding
- Era inference: a Cannon-class (DET-design) destroyer escort built 1943 would have carried era-standard asbestos applications appropriate to a diesel-electric ship - exhaust insulation, gaskets and packing, electrical insulation, brake linings, and deck coverings - with no propulsion boilers or steam-line lagging; the DPHDM-documented pair of auxiliary Cycloterm MC-90 boilers aboard this hull adds a limited auxiliary-steam lagging category. Builder Dravo Corp., Wilmington, Del. is NOT in the Atlas shipyards.json dataset, so no yard-level asbestos documentation attaches to this hull.

- Population
- Dravo Corp. construction trades 1943; crew 1943-45 (USN) and 1945-64 (Marinha do Brasil); 1964 scrapping workforce
- Limitations
- Class/era inference only - NOT a hull-specific finding. The diesel-electric propulsion plant means the largest asbestos categories of steam ships (boiler and steam-line insulation) do not apply; the auxiliary boilers' lagging composition is undocumented; does not quantify material or establish any individual's exposure.

- GAO product page HRD-80-2
- Finding type
- gov_survey
- Finding
- GAO documented the Navy's extensive shipboard asbestos insulation use with substitution not beginning until the early 1970s - this hull's 1943 construction and 1943-45 USN service fall inside the documented asbestos-use era; her 1945-64 Brazilian service postdates U.S. program documentation.

- Finding type
- litigation_documented
- Finding
- No qualifying ship-specific asbestos record located for DE-101: no hull ACM survey, no abatement or hazmat disclosure for the U.S. or Brazilian custody periods, and no qualifying asbestos litigation naming USS Alger or DE-101 in CourtListener searches (hits classified in the search ledger; 'Alger' is a high-collision surname). Hull scrapped in Brazil 1964 - no surviving-hull survey path exists.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard during 1943-64 service - era materials are consistent with the design's documented equipment but not ship-proven. Does not establish or defeat any claim of exposure or legal eligibility. Brazilian-custody (1945-64) material records were not located in U.S. sources.
