- DANFS record for this hull: laid down 12 December 1951 at Norfolk Naval Shipyard; launched 14 March 1953, sponsored by Mrs. Porter Hardy, Jr.; commissioned 25 September 1953, Lt. Douglas C. Pearson in command. DANFS specifications line: dp. 775; l. 172'; b. 35'; dr. 10'; s. 14 k.; cpl. 70; a. 1 40mm., 2 .50-cal. mg.; cl. Aggressive. Bold did not report for normal Mine Force duty for 17 months after commissioning: Bureau of Ships special trials in conjunction with Norfolk Naval Shipyard and New York Naval Shipyard ran early October 1953 to early June 1954, followed by shakedown off New England June 1954 and a five-month Norfolk Naval Shipyard overhaul ending February 1955 (reclassified ocean minesweeper MSO-424, 7 February 1955); Charleston homeport from February 1955. Six Mediterranean deployments with MinDiv 83 / 6th Fleet (1955, 1957, 1958-59, 1961, 1964, 1967); recurring duty as Mine Warfare School training platform (Yorktown) and Naval Mine Defense Laboratory test platform (Panama City, Fla.). Decommissioned at Charleston 2 July 1971; held in reserve until early 1975; stricken 28 February 1975; sold to Tucson One Hour, Inc., of Cincinnati, Ohio, June 1981.

- DANFS documents service history and specifications, not materials or asbestos content. Cited via a Wayback capture of the official NHHC page because the live URL returns 404; an older truncated DANFS transcription (hazegray, ending c.1956, different spec line) also exists. NavSource header dates (launched 14 Mar 1952; commissioned 20 Sep 1953) conflict with DANFS - DANFS carried.

- Finding
- Register-derived record for this hull: call sign November-Oscar-Romeo-Kilo; laid down 12 December 1951 at Norfolk Naval Shipyard, Portsmouth, VA; reclassified ocean minesweeper MSO-424 on 7 February 1955; decommissioned 2 July 1971 at Charleston, SC; struck from the Naval Register 28 February 1975; sold for scrap 1 June 1981 to Tucson One Hour Inc. of Cincinnati, Ohio, for $45,000. Propulsion: four Packard ID1700 diesel engines, two shafts, two controllable-pitch propellers. Armament as built: one 40mm mount and two .50-cal machine guns (final fit substituted one twin 20mm for the 40mm). Commanding-officer roster 1953-1971 (LT Douglas C. Pearson at commissioning through LCDR Joseph W. Streuli at decommissioning).

- NavSource is a volunteer-maintained archive transcribing official registers - chronology is concordant with DANFS, but the underlying NVR page was not retrievable (nvr.navy.mil excludes vessels disposed before 1987). NavSource's header dates (launched 14 Mar 1952; commissioned 20 Sep 1953) conflict with both DANFS and NavSource's own CO roster (Pearson from 25 Sep 1953) - treated as transcription typos and not carried. Documents specifications and register events, not materials or asbestos content.

- Finding type
- asbestos_application
- Finding
- Era/class inference: a wooden-hulled non-magnetic ocean minesweeper (SCB-45A design, DANFS class 'Aggressive') built 1951-53 to early-Cold-War Navy specifications would have carried period-standard asbestos applications - engine exhaust and muffler lagging, machinery-space thermal and acoustic insulation, machinery gaskets and packing, electrical insulation, fire-resistant bulkhead and deck coverings, and winch/windlass brake linings. The documented diesel plant (no boilers or steam mains) and laminated-wood hull remove the boiler, steam-line, and steel-hull lagging components typical of steam-driven hulls, narrowing the probable product profile relative to steam vessels of the same era.

- Limitations
- Class/era inference only - no hull-specific insulation survey, work package, or material list located. The wood/non-magnetic construction and diesel plant are documented at class level (lead ship NYT report, FAS, NavSource index); materials aboard AM-424 specifically are not. Does not establish asbestos presence, quantity, location, or remaining material aboard; does not establish exposure or legal eligibility. NARA RG 19 per-vessel specifications (SCB-45A booklet of general plans) and Norfolk Naval Shipyard work packages are the retrieval paths for hull-level confirmation.

- Finding type
- gov_survey
- Finding
- Peer-reviewed industrial-hygiene study from the Long Beach Naval Shipyard Medical Department documenting measurable asbestos exposure among insulation workers during fabrication, installation, and removal of asbestos insulation on naval vessels undergoing repair and overhaul - the process type performed during this hull's unusually numerous documented yard events (Norfolk Naval Shipyard construction and overhauls 1954-55 and 1960; Charleston Naval Shipyard overhauls 1956 and 1958; civilian-yard availabilities at Jacksonville FL, Savannah Machine & Foundry, the Jacksonville Shipyard at Charleston, and Detyen's Shipyard Mt. Pleasant; inactivation preparations at Charleston 1971).

- Limitations
- Process-level evidence only - the study does not name this hull, does not document work performed on AM-424/MSO-424, and its study site (Long Beach Naval Shipyard insulation shop) is a different facility from any of this hull's documented yards. Supports era-typical exposure conditions during yard availabilities generally, nothing hull-specific.

- Finding
- GAO documented the Navy's asbestos-protection program and insulation-removal policies of the 1970s, with fieldwork at naval shipyards including Norfolk Naval Shipyard - the yard that built Bold and performed her 1954-55 and 1960 overhauls - confirming that asbestos insulation was pervasive in naval construction and repair of the era.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum documentation, or docketed asbestos case naming USS Bold, AM-424, or MSO-424 was found in the public sources searched (see search_ledger). CourtListener authenticated API returned HTTP 429 on 2026-09-22 (2,800/day shared quota exhausted); the indexed litigation surface returned only name collisions - 'Bold'-string matches (Bold Films LP litigation, USS Pueblo FSIA plaintiffs' filings, USS Bonhomme Richard fire documentation) - none qualifying. VA BVA decisions index surfaced no decision naming the ship. Law-firm marketing ship lists (mesothelioma.com minesweepers table naming the hull 'USS Bold | AM-424 | Aggressive | 9/25/1953 | Sold, 1981'; mesotheliomaveterans.org) name the hull with generic era boilerplate and no primary support - excluded source class; their 'boiler rooms' boilerplate is physically inapplicable to this diesel, wooden-hulled hull.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - 1951-53 naval construction makes era-consistent material plausible but not ship-proven, and the hull was scrapped in 1981 before modern disposal-disclosure practices. Does not establish or defeat any claim of exposure or legal eligibility. Litigation check is partially degraded by the CourtListener API throttle; unindexed or uncrawled dockets could still name the hull.

- Finding
- NARA holds digitized deck logs for this hull (example located: December 1966, NAID 182655236, National Archives at College Park). RG 19 Bureau of Ships construction records (booklets of general plans, per-vessel material specifications for the SCB-45A design) and Norfolk Naval Shipyard construction/overhaul work packages are the standard repositories in which hull-specific insulation and materials documentation for AM-424 would reside. None were retrieved through digitized public channels in this pass beyond the located deck-log record.

- Limitations
- The December 1966 deck-log record's existence is verified; its content was not reviewed - deck logs record operations and personnel, not materials inventories, so any asbestos relevance would be incidental. Existence of a Bold-specific booklet of general plans or material list within RG 19, and of NNSY work packages for this hull, is unconfirmed.
