USS Sioux City (LCS-11), a Freedom class littoral combat ship, was commissioned at Marinette Marine in January 2018 and has served in the Atlantic Fleet homeported at Naval Station Mayport, Florida. Sioux City is powered by two gas turbines and two diesel engines with waterjet propulsion and has conducted counter-drug operations in the Caribbean. Commissioned in 2018, Sioux City incorporated hull insulation, pipe lagging, gaskets, and construction materials consistent with 2018 naval construction specifications.

USS Sioux City Hull Construction and Systems Asbestos

Sioux City’s hull construction and onboard systems incorporated asbestos in multiple areas:

  • Hull and structural insulation — Sioux City’s crew berthing, mission bay, and engineering spaces were constructed with insulation materials consistent with 2018 naval construction specifications, which according to publicly filed litigation records included asbestos-containing materials
  • Auxiliary piping systems — Sioux City’s auxiliary piping systems and associated pipe lagging incorporated asbestos-containing insulation materials consistent with 2018 construction specifications
  • Gaskets and packing materials — Sioux City’s engineering spaces incorporated gaskets and valve packing consistent with 2018 construction specifications, which according to publicly filed litigation records included asbestos-containing materials
  • Fire-protective and thermal barriers — Sioux City’s engineering compartments and mission spaces incorporated fire-protective insulation materials consistent with 2018 naval construction standards

VA Claims for USS Sioux City 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. Gas Turbine System Technicians, Machinist’s Mates, Boatswain’s Mates, and crew members who served aboard USS Sioux City 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 Sioux City

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.
