Asbestos Exposure Aboard Various repair ships AR Ships

Asbestos was the standard thermal insulation material aboard U.S. Navy tenders & repair ships built before approximately 1980. On ships of this type, asbestos-containing materials were concentrated in the areas below.

  • Tender's own engineering spaces — boiler and turbine insulation
  • Machine shops — asbestos-containing gasket material cut and fabricated for repairs
  • Repair party equipment — asbestos gloves, blankets, and patching material
  • Transferred work: insulation disturbed on visiting destroyers, submarines, and smaller craft

Destroyer tenders of the Dixie class (commissioned 1940–1945) and submarine tenders of the Fulton class served through the Cold War. Repair ships (ARS/AR class) were forward-deployed to Vietnam-era operations. The repair mission made tenders particularly high-exposure environments.
