USS Essex (CVA-9) was a Essex-class aircraft carrier (lead ship) that served the U.S. Navy from 1942 through 1969 — a 27-year service life that places her squarely within the heaviest period of asbestos use in U.S. Navy ship construction. Across her service, Essex’s crew worked daily in machinery spaces, engineering plant, and habitable compartments constructed with extensive asbestos-containing materials.

The equipment manifest below is drawn from BUSHIPS (Bureau of Ships) ship-specific documentation that identifies the machinery and equipment manufacturers installed aboard Essex. Each entry is a documented item of equipment with verified manufacturer attribution — primary-source evidence for asbestos-exposure case development by Navy veterans and their families.

Asbestos-Containing Materials Aboard Essex

The standard asbestos-containing materials installed throughout U.S. Navy ships of this era are documented to have included:

  • Pipe lagging and thermal insulation on steam, feed-water, fuel-oil, condensate, and saltwater piping throughout machinery spaces
  • Boiler block insulation, refractory brick, and gun-blocks around the main boilers
  • Asbestos gaskets and braided packing in valves, flanges, pumps, condensers, heat exchangers, and turbine glands
  • Insulation jackets and removable lagging on turbines, reduction gears, and auxiliary machinery
  • Sheet asbestos and Marinite panels as fire-stops, bulkhead insulation, and overhead insulation
  • Vinyl asbestos floor tile (VAT) in passageways, berthing, mess decks, and habitable spaces
  • Asbestos rope, wick, and tape in glands, joints, and seal applications

Sailors in Boilerman, Machinist’s Mate, Engineman, Electrician’s Mate, Hull Maintenance Technician, Damage Controlman, and other engineering ratings worked routinely in spaces where these materials were installed, maintained, and overhauled.

VA Benefits for Essex Veterans

The Department of Veterans Affairs recognizes mesothelioma, asbestos-related lung cancer, asbestosis, and pleural disease as conditions presumed to be service-connected for Navy veterans with documented asbestos exposure. The documented Essex equipment manifest is direct evidence of the asbestos-containing materials her crew worked around.

Parallel claims against the asbestos bankruptcy trust funds established by the manufacturers of these products are also available, and do not reduce VA compensation.
