The Mispillion T-AO-105 was a class of U.S. Navy auxiliary & supply ships from the asbestos era, led by USS Mispillion (T-AO-105). Its 5 ships used asbestos-containing insulation throughout the engineering plant, and veterans who served aboard Mispillion T-AO-105 vessels — especially in engineering ratings — may have been exposed to asbestos fibers.

Asbestos Exposure Aboard Mispillion T-AO-105 Ships
Asbestos was the standard thermal insulation material aboard U.S. Navy auxiliary & supply ships built before approximately 1980. On ships of this type, asbestos-containing materials were concentrated in the areas below.
- Main engineering spaces — boiler and turbine insulation, steam piping
- Cargo pump rooms (oilers) — thermal and pump insulation
- Hospital compartments (hospital ships) — overhead and bulkhead insulation in some spaces
- Fuel transfer system piping — pipe lagging throughout the ship
- Gaskets and valve packing in all engineering spaces
Fleet oilers of the Cimarron and Neosho classes, ammunition ships of the Nitro and Suribachi classes, and combat stores ships of the Mars class all served through the 1970s with asbestos-insulated propulsion plants.

At-Risk Ratings Aboard Mispillion T-AO-105 Ships
The following ratings had regular contact with asbestos-containing materials aboard auxiliary & supply ships of this era. If you served in one of these ratings, document it when filing a VA disability or asbestos trust fund claim.

VA Benefits & Legal Options for Mispillion T-AO-105 Veterans
Veterans diagnosed with mesothelioma, asbestosis, pleural plaques, or asbestos-related lung cancer who served aboard Mispillion T-AO-105 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 Mispillion T-AO-105 ships use asbestos?
Yes. The Mispillion T-AO-105 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 Mispillion T-AO-105 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 Mispillion T-AO-105 ships?
Common asbestos products used in U.S. Navy auxiliary & supply 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 Mispillion T-AO-105?
If you or a family member served aboard Mispillion T-AO-105, you may have been exposed to asbestos. Sharing your service information is completely voluntary and may help build the historical record of shipboard exposure — information that can be valuable in VA disability and asbestos trust fund claims.
