- DANFS record for this hull ('Dupont III'): launched 8 September 1956 by Bath Iron Works Corp., Bath, Maine; sponsored by Mrs. H. B. Du Pont, great-great-grandniece of Rear Admiral Du Pont; commissioned 1 July 1957, Commander W. J. Maddocks in command. Spec block: Forrest Sherman class; dp 3,807 (f.); l. 418'5"; b. 45'1"; dr. 14'2"; s. 30 k.; cpl. 311; a. 3 5", 4 3", 4 21" tt., 1 dct. Service narrative through 1960: midshipman cruise and antisubmarine exercises in the Atlantic 6-31 July 1958; first Sixth Fleet Mediterranean tour from 2 September 1958 returning to Norfolk 12 March 1959; Operation 'Inland Sea' - first naval task force passage into the Great Lakes via the St. Lawrence Seaway - escorting HMS Britannia with Queen Elizabeth II embarked at the 26 June 1959 dedication; plane guard for President Eisenhower's transatlantic flight and Southampton visit August-September 1959; second Sixth Fleet tour from 28 January 1960, returning 31 August for Norfolk Naval Shipyard overhaul through end of 1960.

- DANFS documents service history and specifications, not materials or asbestos content. Entry coverage ends in 1960 (typical for a ship then still in service) - post-1960 history relies on association publications (ev-04). Mirror transcription cited because the live NHHC page returns 404 (standing link-rot defect since batch-01).

- Official register record - strongest source for milestone and disposition dates. NVR does not record the 1969-1970 inactivation/recommissioning cycle (only the final decommission) and carries no materials or hazmat content. 'Disposed of, by Navy Sale' effective 12/11/1992 is the status-change date; NavSource records the actual sale closing 14 January 1993.

Photo captions document yard/port presence but not the scope of industrial work. The first decommissioning date (16 May 1969) conflicts with the Naval Cover Museum's 23 May - carried in gaps.

Ballant and wounded eight, ~75 combat days and 20,000 rounds of 5-inch fire in the tour; second Vietnam tour 1968-1969 covering Mekong Delta, Gulf of Siam, and I Corps/Da Nang in support of SEAL teams, ARVN units, and amphibious landings (~30,000 rounds Vietnam-era total); Boston Naval Shipyard May 1969 for decommissioning and ASW modernization; recommissioned 9 May 1970; Atlantic/Caribbean/Mediterranean operations; 1974 mast damage passing the Coleman Memorial Bridge at Yorktown (~one month pier-side repairs); Middle East deployment returning March 1977; final deployment August-December 1982 - ~74 days on station off Beirut, naval gunfire support during the PLO evacuation and escort of the multinational peacekeeping force after the September massacres; decommissioned 4 March 1983.

- Finding
- HAER DC-69 documents the Forrest Sherman class (18 destroyers, DD-931/934-951 series, built 1953-1959): steel hulls with aluminum superstructures; four boilers in two firerooms at 1,200 psi feeding geared steam turbines on twin screws at 70,000 shp for 33 knots design speed; design accommodations for 315 enlisted plus 22 officers; class dimensions ~418' overall. DD-941 is within the documented class series (NVR class code DD 931). The document records class design and construction history - it contains no asbestos or hazardous-materials content and no hull-specific material callout for DD-941.

No source located names a specific asbestos-containing product installed aboard DD-941, and no quantity, location, condition, or abatement outcome is documented.

MDL-875 pleading-stage complaints naming DD-941 may exist unindexed by this sweep. 'Du Pont' is a high-collision term (chemical company + common surname); any future hit must be checked for the hull number or a Navy vessel reference before qualifying.
