Asbestos Exposure Aboard De Soto County LST-1171 Ships
Asbestos was the standard thermal insulation material aboard U.S. Navy amphibious ships built before approximately 1980. On ships of this type, asbestos-containing materials were concentrated in the areas below.
- Main propulsion plant — boiler and turbine insulation, steam piping
- Vehicle and cargo decks — deck tile adhesives and flooring materials
- Well deck machinery — ramp and flooding system piping insulation
- Crew berthing — overhead insulation in some ships
- Machinery room pipe lagging and gaskets
WWII-era LSTs, LSDs, and attack transports through the Tarawa-class LHAs (commissioned 1976–1980) represent the amphibious asbestos era. The Wasp class (LHD-1, commissioned 1989) marks the transition to reduced asbestos use.

VA Benefits & Legal Options for De Soto County LST-1171 Veterans
Veterans diagnosed with mesothelioma, asbestosis, pleural plaques, or asbestos-related lung cancer who served aboard De Soto County LST-1171 ships may be eligible for:
- VA disability compensation — monthly benefit; requires diagnosis plus evidence of shipboard service. No manufacturer identification needed.
- Asbestos trust fund claims — lump-sum payments from trusts funded by bankrupt asbestos manufacturers (Johns-Manville, Owens Corning, and others). Requires identifying specific products used aboard.
These two paths are not mutually exclusive. Many veterans pursue both.

Frequently Asked Questions
Did De Soto County LST-1171 ships use asbestos?
Yes. The De Soto County LST-1171 was built during the era when asbestos was the standard insulation material in U.S. naval construction. Engineering spaces aboard these vessels contained asbestos pipe lagging, boiler block insulation, gaskets, and valve packing. Veterans who worked in boiler rooms, engine rooms, or repair roles had the highest likelihood of exposure.
How do I prove I served aboard a De Soto County LST-1171 ship for a VA claim?
Your DD-214 (Certificate of Release or Discharge from Active Duty) lists your ship assignments. Additional documentation includes ship deck logs (available from the National Archives), official orders, and buddy statements from fellow crew members. A Veterans Service Organization (VSO) can help you gather and submit this evidence at no cost.
What asbestos products were used aboard De Soto County LST-1171 ships?
Common asbestos products used in U.S. Navy amphibious ships of this era included Kaylo pipe insulation (Owens-Illinois), Unibestos block insulation (Pittsburgh Corning), 85% magnesia pipe covering (various manufacturers), Flexitallic spiral-wound gaskets, and Johns-Manville pipe covering. A mesothelioma attorney who specializes in Navy claims maintains detailed product-identification databases for specific ship classes.
Did You Serve Aboard De Soto County LST-1171?
