The MSOs 'were smaller and built primarily of wood, with bronze and stainless (non-magnetic) steel fittings to minimize their magnetic signature,' and 'All of the 1950 era MSOs had UQS-1 mine-locating sonar, later updated with SQQ-14 sonar.' MSO-489 sits inside the 421-507 Agile/Aggressive hull range - the citable source for the wooden, non-magnetic construction and for the dual class name.

- Yard-level documentation of this hull's builder and build program: Martinac (1924-2014, east shore of the Thea Foss Waterway) announced contracts in August 1951 for four 172-foot minesweepers worth nearly $9 million with ~300 workers planned; work started January 1952 (first hull, Endurance AM-435, launched 8 August 1952); before the second launched in early 1953 Martinac received orders for five more minesweepers for $8 million - nine total, the last 'slid down the ways in the summer of 1955.' Construction detail: 'the firm leased additional space at the Baker dock where pieces of white oak were laminated together for the ship's ribs. They used fir and red oak for planks, and extensive efforts were made to use non-ferrous metals as much as possible throughout the sweepers to reduce their magnetic signatures' - corroborating the NavSource index's wooden/non-magnetic framing at the performing yard.

- Era-level inference only: peer-reviewed scholarship documents extensive asbestos use as a fireproofing and insulating material in U.S. shipbuilding of the era in which this minesweeper was designed and built. Aboard a ~780-ton wooden-hulled diesel ocean minesweeper the plausible applications, if any, were confined to machinery fittings - era-standard gaskets, valve packing, exhaust-system insulation, and electrical insulation - a materially narrower scope than steam-driven vessels carry; the Packard/Waukesha diesel plant has no boiler or steam-line insulation envelope. No construction-level material list for this hull or the MSO type was located.

- Finding
- GAO documented the Navy's asbestos position in 1979: 'although all ships contain some asbestos in such components as clutches and electric cables, most ships delivered in the last several years or now under construction have little or no asbestos as thermal insulation, which was the Navy's major use of asbestos aboard ships'; 'thermal insulation for machinery, equipment and piping systems has been the major application of asbestos'; 'some ships were delivered with asbestos insulation as late as May 1978'; 'other Navy ships contain large quantities of asbestos'; 'all ships presently in service contain some quantity of asbestos.' Thermal-insulation specifications changed in 1973 and a substitution-elimination policy issued October 1975; the Navy's removal policy replaced only damaged or work-required insulation, 'the 30 to 50 percent which normally remains untouched, except for minor maintenance, during the life of a ship' staying in place. This hull's construction (1953-55) and service era (1955-94) sit entirely inside the documented asbestos-use window.

- Finding
- CORRECTION/discrepancy record, documented not reconciled: (a) DANFS entry typo - the published Gallant II entry prints '(AM-498)' in the opening sentence and 'MSO^89' in the reclassification clause (raw-HTML verified); every other source (NVR, NavSource, Colton, master hull list) confirms AM-489/MSO-489. AM-498 is not a vacant number - it is a real MSO-program hull built for Norway (Lagen M 950, later Belgium's Dufour M 903, per the NavSource index) - so the DANFS typo risks attributing Gallant's keel to a different minesweeper and is flagged, not propagated. (b) class name - 'cl. Aggressive' (DANFS stats line), 'Aggressive Class' (NavSource page, master hull list) vs 'Agile-class' (Wikipedia class article) vs NavSource index 'Agile/Aggressive' (hulls 421-507) - documented dual class name.

R. Stoneleigh), 3rd then 1st Naval District patrol/training duty out of New York and Boston, decommissioned 22 January 1945, returned to her former owner via WSA 28 June 1945 (DANFS Gallant I).

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum/yard material disclosure, or verified litigation naming USS Gallant (AM-489/MSO-489) was found in the public sources searched (see search_ledger). CAVEAT: CourtListener could not be queried this session - the authenticated API reported the fleet daily quota exhausted (~4.6 h to reset); logged as blocked in the search ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case; the only 'asbestos aboard' material is law-firm marketing content listing 'USS Gallant' on ship-list pages (mesotheliomaveterans.org, simmonsfirm.com, sokolovelaw.com, elslaw.com, freeasbestostesting.com) - excluded by source policy, no primary sourcing.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1953-55-built naval vessel is era-consistent with asbestos-containing machinery fittings even accounting for the diesel/wooden-hull profile. The litigation repository search is a genuine open gap (throttled, not run); RECAP indexing caveats apply in any case. The hull may still exist in Taiwanese custody - a surveyable structure, but no survey was located. Does not establish presence or absence; does not establish or defeat any claim of exposure or legal eligibility.
