USS Canopus (AS-34) was a Simon Lake-class submarine tender commissioned 4 November 1965 and serving the U.S. Navy through 1994 — supporting the Atlantic Fleet ballistic-missile submarine force throughout the Cold War from forward bases at Rota, Spain and Holy Loch, Scotland.

The 52-entry equipment manifest below is sourced from ship-specific BUSHIPS (Bureau of Ships) documentation identifying machinery and equipment installed aboard. Each entry is documented equipment with verified manufacturer attribution — primary-source material for asbestos-exposure case development by Navy veterans and surviving families.

Asbestos-Containing Materials Aboard Canopus

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

  • Pipe lagging and thermal insulation on main 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 main propulsion turbines, reduction gears, ship-service turbine generators, and forced-draft blowers
  • 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 compartments
  • Asbestos rope, wick, and tape in gland-seal applications throughout the engineering plant

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, ripped out, and replaced.

VA Benefits for Canopus 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 Canopus equipment manifest is direct documentary evidence of the asbestos-containing materials her crew worked around throughout her service life.

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