USS Aspro (SSN-648), a Sturgeon class nuclear attack submarine, was commissioned at Ingalls Shipbuilding in February 1969 and served in the Pacific Fleet. Aspro conducted Cold War anti-submarine warfare patrols in the Pacific, tracking Soviet submarine activity, and performed intelligence collection operations during the Cold War. Aspro’s nuclear propulsion plant drove steam turbines providing propulsion through her service. Commissioned in 1969, Aspro incorporated asbestos-containing steam system insulation, reactor compartment insulation, and hull construction materials consistent with the Sturgeon class late 1960s construction specifications.

USS Aspro Nuclear Propulsion Plant Asbestos

Aspro’s nuclear steam propulsion plant incorporated asbestos in critical system insulation:

  • Nuclear steam plant insulation — Aspro’s secondary steam system, steam generators, and associated high-pressure steam piping incorporated thermal insulation materials consistent with late 1960s naval nuclear construction specifications, which according to publicly filed litigation records included asbestos-containing insulation materials
  • Propulsion turbine insulation — Aspro’s main propulsion turbine and reduction gear system incorporated insulation materials consistent with the late 1960s nuclear submarine construction specifications
  • Hull construction materials — Aspro’s crew berthing, operations compartment, and working spaces were constructed using the hull construction materials of the late 1960s Sturgeon class building program

VA Claims for USS Aspro Veterans

VA evaluates asbestos-related disability claims on a case-by-case basis. Veterans generally need evidence of in-service asbestos exposure, a current asbestos-related diagnosis, and a medical link between them. Nuclear-trained ratings, Engineering ratings, and crew members who served aboard USS Aspro and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.

Navy Ratings Most Exposed to Asbestos Aboard Aspro

The U.S. Department of Veterans Affairs and the public asbestos litigation record document that the following Navy ratings worked routinely in spaces where ACM was installed, maintained, ripped out, and replaced:

VA Disability Claims for Asbestos-Related Disease

The U.S. Department of Veterans Affairs evaluates asbestos claims individually. A veteran generally needs medical evidence of a current asbestos-related disease, service evidence supporting in-service asbestos exposure, and a medical opinion connecting the two. Ship assignments, Navy ratings, and equipment records can help document the exposure history but do not create automatic service connection.

Approved claims may provide monthly disability compensation and related benefits. Survivors may separately qualify for Dependency & Indemnity Compensation when the applicable requirements are met. Civil lawsuits and asbestos-trust claims use different standards; claimants should obtain individualized advice about how the processes interact.

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.
