'The second Dash (AM-428) was launched 20 September 1952 by Astoria Marine Construction Co., Astoria, Oreg.; sponsored by Mrs. D. McKay; and commissioned 14 August 1953, Lieutenant Commander R. Giamotti in command. She was reclassified MSO-428, 7 February 1955.' Sailed from San Diego 12 June 1954, arrived Charleston, S.C. 6 July; local duty and refresher training at Key West until 4 January 1956, then a Mediterranean Sixth Fleet tour returning to Charleston 11 June; Mediterranean again 1 May-2 October 1957 and 27 April-27 August 1959; 'Through 1962, she operated along the east coast and in the Caribbean in amphibious and mine warfare exercises.' The entry (DANFS Vol. II, 1963) does not cover post-1962 service, decommissioning, or disposal.

Significance periods 1941-1945 (first Navy contract 1 April 1941) and 1950-1955 (Korean War MSO contract award through completion); 7.2-acre district, 15 contributing resources. Confirms the builder, the Korean War MSO program context, and AM-428 as the first-produced hull of the program.

'First MSO Type I minesweeper' refers to AM-428's launch/production precedence (20 Sep 1952 launch, earliest in-service date 14 Aug 1953 in the Combat Fleets table) - keel dates of sisters were earlier (Aggressive laid down 25 May 1951).

- Finding type
- asbestos_application
- Finding
- Era/design inference for this hull type: the 1950s MSO program (SCB-45A series) comprised ~100 wooden minesweepers built of wood with bronze and non-magnetic stainless-steel fittings to minimize magnetic signature, $3.5M/ship in 1951; designated AM and reclassified MSO February 1955. Class table line: '(4) DASH Class, 428-431, 172 ft, 35 ft, 775 tons, 10 ft, 8 and 70, 14 knots, General Motors, 1520 SHP'; remarks: '428,429,430,431 had 2 General Motors diesels at 1520 hp' - the Dash-class distinction from the four-Packard Agile/Aggressive plant. A diesel direct-drive plant with no boilers or steam system means a materially lighter insulation load than steam combatants; era-typical asbestos applications for a 1950s naval vessel of this type: machinery gaskets and packing, exhaust-system lagging, electrical-cable insulation, accommodation/galley joiner materials, deck coverings/floor tile, brake linings. Exposure-relevant populations if any material was present: AMCCO construction trades (Astoria, 1951-53); the commissioned crew (~74-78) across 1953-1982; yard workers at undocumented availabilities; the 1984 scrapping workforce (Wayne Hobbs, Huntington CA).

- Finding
- Program-level documentation of the asbestos window containing this hull's entire career: the Navy's product specifications for thermal insulation were changed in 1973 to specify asbestos-free materials, but asbestos materials already purchased were still installed - 'some ships were delivered with asbestos insulation as late as May 1978'; the Navy's elimination policy issued October 1975. The 5 January 1979 Navy letter states 'all ships presently in service contain some quantity of asbestos' and enumerates era applications: asbestos in Navy electronic-equipment resistors, floor tiling 'on Navy ship decks,' electric cabling and galley ranges, piping-system gaskets and packing, and equipment brakes and clutches. Dash was built 1951-53 and in commission 1953-1982 - entirely within the pre-1973 as-built asbestos era and the 1979 all-ships statement's window.

The hull was scrapped in the U.S. in 1984 by a commercial buyer with no museum or memorial disposition, so no steward-organization disclosure exists.

Web-indexed searches of the CourtListener corpus surfaced only name collisions: Damon Dash / Roc-A-Fella entertainment litigation (S.D.N.Y.); 'Dash Computers, Inc.' in the CRT-antitrust MDL (N.D. Cal. MDL 1917); asbestos opinions and RECAP documents naming other ships (USS Barney, Oriskany, Midway, Rushmore). Site-scoped VA BVA searches surfaced decisions naming other vessels (William V. Pratt, America, Sacramento, Hornet, Oriskany) - no hit for this hull.

- Finding
- Class-adjacent asbestos litigation exists for this vessel type: plaintiffs alleged decedent John Dale Wineland was exposed to asbestos-containing products while working engine rooms aboard Navy ships 1963-1984, including Agile/Aggressive-series ocean minesweepers USS Dynamic (MSO-432, 1963-66), USS Pledge (MSO-492, 1966-67), USS Loyalty (MSO-457, 1970-72), and USS Esteem (MSO-438, 1978-80) - wooden-hulled diesel MSO sisters of this hull in the same SCB-45A design family. The opinions record machinery-space work on 'diesel engines, pumps, air compressors, and valves.' Disposition per litigation-stage discipline: the located rulings are summary-judgment-stage defense wins (Crane Co. MSJ granted, 539 F. Supp. 3d 1149; companion MSJs granted) - merits-level negatives for that plaintiff, not exposure findings; the vessel/product allegations are pleadings and motion-stage record assertions, not adjudicated facts.
