Naval Station Mayport — located in Mayport, Florida, at the mouth of the St. Johns River near Jacksonville — is the United States Navy’s third-largest fleet concentration area on the East Coast, serving as the primary homeport for destroyers, frigates, and amphibious assault ships assigned to the Atlantic Fleet. Naval Station Mayport has operated continuously since World War II, growing into a major fleet support installation with extensive pier facilities, ship repair yards, and support infrastructure for the surface combatant fleet. The ships homeported at Mayport — destroyers, frigates, and amphibious vessels — were built and outfitted with asbestos insulation, asbestos gaskets, and asbestos packing throughout their engineering spaces, creating asbestos exposure for the Machinist’s Mates, Boiler Technicians, and engineering ratings who operated and maintained these vessels. The station’s maintenance and support facilities — pier facilities, ship repair shops, and support buildings — incorporated asbestos-containing materials throughout their construction and operations. Publicly filed asbestos litigation records document Naval Station Mayport in formal Navy asbestos documentation, veteran testimony specifically identifying Mayport as a station location during the asbestos exposure era, and Mayport in the formal naval asbestos litigation framework.

Asbestos at Naval Station Mayport

Destroyer and frigate engineering spaces: The surface combatants homeported at Mayport — destroyers and frigates built in the 1950s through 1970s — were equipped with steam propulsion systems surrounded by asbestos insulation throughout their engineering spaces. Machinist’s Mates and Boiler Technicians who maintained these ships’ propulsion plants at Mayport were exposed to asbestos at every maintenance interval.

Ship repair and maintenance facilities: Naval Station Mayport’s ship repair facilities supported the maintenance of the homeported fleet — with ship repair work requiring the removal and replacement of asbestos insulation to access piping, valves, and mechanical systems. Repair operations generated the highest-intensity asbestos exposures, as old, friable insulation was disturbed in confined engineering spaces.

Pier facilities and support infrastructure: The pier facilities and support buildings at Naval Station Mayport were constructed during the base’s WWII and Cold War expansion periods — incorporating asbestos-containing materials in building construction that remained in place throughout the subsequent decades of operations.

Amphibious vessel operations: Naval Station Mayport also served as a homeport for amphibious assault ships — larger vessels with extensive engineering plants and accommodation areas where asbestos-containing building materials were installed throughout the vessel during construction.

Navy veterans who were stationed at Naval Station Mayport and served aboard surface combatants homeported there, particularly Machinist’s Mates and Boiler Technicians who maintained engineering plants on Mayport-homeported vessels, and who subsequently developed mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease, may qualify for:

  • VA presumptive service connection under 38 CFR § 3.309(d) for veterans with documented duty at Naval Station Mayport in engineering maintenance roles
  • Civil claims against asbestos product manufacturers whose materials were used in vessels homeported at Mayport and in Mayport’s support facilities

Key documents:

  • DD-214 or service records — documenting assignment to Naval Station Mayport or to vessels homeported at Mayport
  • Rating records — Machinist’s Mate (MM) or Boiler Technician (BT) with documented Mayport duty or duty on Mayport-homeported vessels
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
