USS Delaware (SSN-791), a Virginia class Block IV nuclear attack submarine, was commissioned at Newport News Shipbuilding in April 2020 and homeported at Naval Station Norfolk, Virginia. Delaware operates as a multi-mission platform capable of anti-submarine warfare, strike missions, and special operations support. Delaware’s S9G nuclear propulsion plant drove steam turbines providing propulsion through her service.

USS Delaware Nuclear Propulsion Plant Asbestos

Delaware’s nuclear steam propulsion plant incorporated insulation in critical system components:

  • Nuclear steam plant insulation — Delaware’s S9G secondary steam system, steam generators, and associated high-pressure steam piping incorporated thermal insulation materials consistent with 2020 naval nuclear construction specifications, which according to publicly filed litigation records may have included asbestos-containing insulation materials in certain legacy-specified systems
  • Propulsion turbine insulation — Delaware’s main propulsion turbine and reduction gear system incorporated insulation materials consistent with the Virginia class construction specifications
  • Hull construction materials — Delaware’s crew berthing, torpedo room, operations compartment, and working spaces were constructed using the hull construction materials of the Virginia class Block IV building program

VA Claims for USS Delaware Veterans

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure from Navy nuclear submarine service. Nuclear-trained ratings, Engineering ratings, and crew members who served aboard USS Delaware and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.

VA Presumptive Benefits — No Filing Deadline

The U.S. 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 under 38 CFR § 3.309(d). No statute of limitations applies to VA disability compensation claims.

Available benefits may include monthly disability compensation, Dependency & Indemnity Compensation (DIC) for surviving spouses, priority VA healthcare enrollment, and Special Monthly Compensation for severe cases. Parallel claims against the asbestos bankruptcy trust funds established by the manufacturers of these products do not reduce VA compensation.

How to file a VA disability claim: VA claims are filed directly with the U.S. Department of Veterans Affairs — not with a law firm. Start at VA.gov › Hazardous Materials Exposure, call 1‑800‑827‑1000, or get free help filing from a Veterans Service Organization: DAV, VFW, or American Legion.
