Laid down 20 January 1943 at Charleston, S.C., by the Charleston Navy Yard; launched 7 April 1943, sponsored by Mrs. Roland S. Morris; commissioned 4 November 1943, Comdr. John B.

- Finding
- Era/yard inference: this hull is a WWII Fletcher-class destroyer built in 1943 at the Charleston Navy Yard carrying the class-standard steam plant (4 Babcock & Wilcox boilers, 2 geared steam-turbine sets, 60,000 shp, 2 shafts per the class profile's BuShips Ships' Data 1945 and navypedia verification). Steam destroyers of this configuration and era carried period-standard asbestos boiler and steam-line insulation, turbine lagging, valve/flange gaskets, machinery packing, fireproofing, and deck coverings. The builder yard is documented at yard level in the Atlas shipyards dataset (charleston-naval-shipyard, evidence tier 2): documented products include magnesia pipe insulation, pipe insulation of 5-50% asbestos content, boiler external coatings with 15% asbestos, spray-on insulation for ship interiors, asbestos gaskets in pumps and valves, and packing for rotating equipment; OSHA inspection 100361849 (1988) cites the yard under the asbestos standard 29 CFR 1910.1001 - yard-level evidence, not a hull finding.

No BuShips material schedule, insulation specification, or hull-level survey naming DD-591 was located (NARA RG 19 retrieval not performed). The yard OSHA record postdates this hull's 1943 construction by 45 years and documents late-20th-century yard conditions, not wartime shipbuilding content. The April-May 1945 forward-area repair of this hull by Nestor (ARB-6) is documented as an event (ev-01); any insulation disturbance in that repair is inference, not documented. Does not quantify material or establish any individual's exposure.

- Finding type
- gov_survey
- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - placing this hull's construction (1943) and its entire commissioned service (November 1943-June 1945) inside the documented asbestos-use era. The hull was lost decades before the substitution era began, so any period-installed asbestos-containing material remained aboard at loss.

The configuration of the loss record limits what could exist: the hull was a total loss on 16 June 1945 - there was no postwar disposal, mothballing, overhaul, museum, or domestic scrapping phase under which asbestos documentation would typically be generated; the hulk passed to the Ryukyu Islands government (1957 per secondary compilations, 1967 per DANFS) and any scrapping occurred outside U.S. documentation channels.
