- DANFS title/specifications block and service-history paragraphs
- Finding type
- vessel_history
- Finding
- Official DANFS identifies Timmerman as a Bath Iron Works-built experimental destroyer, launched 19 May 1951 and commissioned 26 September 1952; it tested an advanced propulsion system, was redesignated AG-152 on 11 January 1954, decommissioned at Boston on 27 July 1956, declared unfit and struck from the Navy list on 4 April 1958, and sold to Boston Metals Co. at Baltimore on 21 April 1959 for scrapping. DANFS gives a design complement of 367 and identifies the hull as Gearing class.

- Bath Iron Works construction workforce; Navy crew and test personnel, 1951-1956
- Limitations
- DANFS records service history and specifications, not asbestos content or exposure. The page displays a laid-down date of 1 October 1954, which is impossible with its 1951 launch and 1952 commissioning and conflicts with the official Bath Iron Works history; the date is not treated as reliable without archival correction.

- Finding type
- historical_record
- Finding
- Bath Iron Works' official history describes Timmerman as BIW hull 272, a destroyer left incomplete at the end of World War II with construction suspended at approximately 46 percent completion; it records delivery at Boston Navy Yard on 23 September 1952, commissioning shortly afterward, designation as EDD-828, later redesignation as AG-152, and scrapping after striking in 1958. It also describes the experimental plant as two separate systems: two 875-psi boilers on the starboard shaft and two 2,000-psi boilers on the port shaft.

- Limitations
- This official company history corrects the chronology problem in the live DANFS page and supports the experimental-plant description, but it does not provide a hull-level asbestos inventory or prove asbestos content in any named component.

[4]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (18 October 1979) [gao]
- Locator
- GAO HRD-80-2 product page and report description
- Finding type
- gov_survey
- Finding
- GAO's Navy asbestos-program review provides era context: Navy shipboard asbestos insulation was widespread and substitution did not begin until the early 1970s; Navy policy in the 1970s generally removed insulation when damaged or when repairs required it. Timmerman's 1945-1952 construction and 1952-1956 service fell within that documented era.

- Population
- Navy shipyard workers and shipboard personnel
- Limitations
- Program-level context only; it does not identify asbestos aboard Timmerman, quantify material, establish an exposure, or show that this hull underwent asbestos removal. The full GAO text was not retrievable from the automated product page.

[5]NHHC/DANFS Timmerman propulsion description, read with GAO HRD-80-2 era context [other_primary]
- Locator
- DANFS experimental-propulsion history; GAO HRD-80-2 era context
- Finding type
- asbestos_application
- Finding
- Era/design inference only: Timmerman's steam propulsion plant and associated boilers, turbines, steam lines, valves, and machinery would have required thermal insulation and sealing materials in the construction era; those material categories may include pipe lagging, boiler insulation, turbine lagging, gaskets, and packing. No source located for this research directly identifies any of those products as asbestos-containing aboard DD-828.

- Limitations
- Class/era inference cannot become a ship-specific finding. This row does not establish asbestos presence, quantity, location, removal status, or individual exposure aboard Timmerman; it only explains why archival material specifications are a worthwhile lead.

- Finding type
- litigation_documented
- Finding
- No ship-specific asbestos survey, abatement record, hazmat disclosure, or material schedule for USS Timmerman (DD-828) was located in the authoritative sources searched. The absence of a located record is recorded as a research result, not proof that asbestos was absent.

- Limitations
- Public-source absence is not proof of absence. NARA Bureau of Ships construction files, Bath Iron Works hull records, and Navy inactive-ship disposal files remain archival leads. The required authenticated CourtListener searches were attempted but blocked by the fleet pacing stand-down before results could be returned; therefore no litigation no-result conclusion is drawn.

[7]Authenticated CourtListener helper attempt; fleet-wide pacing stand-down returned before search results [court_record]
- Locator
- cl-auth-search.py authenticated request output; stand-down message at 2026-09-27
- Finding type
- litigation_documented
- Finding
- The required authenticated search was initiated for exact-name and hull-number queries, including "USS Timmerman", "U.S.S. Timmerman", "Timmerman" + "DD-828", "DD-828" + asbestos, and "USS Timmerman" + asbestos. The helper then reported that the fleet-wide request budget was momentarily spent and instructed the session not to retry in a loop. No hit was classified because no result set was returned.
