⚓ U.S. Navy — Auxiliary & Supply Ships
Cimarron AO-177
The Cimarron AO-177 consisted of 5 vessels. Like all U.S. Navy auxiliary & supply ships built during the asbestos era, these ships used asbestos-containing insulation throughout their engineering plants. Veterans who served in engineering spaces aboard Cimarron AO-177 ships may have been exposed to asbestos fibers.
Asbestos Exposure Aboard Cimarron AO-177 Ships
Asbestos was the standard thermal insulation material in U.S. Navy auxiliary & supply ships built before approximately 1980. Common sources of asbestos exposure aboard Cimarron AO-177 vessels included:
- Pipe lagging and block insulation in boiler rooms and engine rooms
- Gaskets at pipe flanges throughout the engineering plant
- Valve stem packing and pump seals
- Turbine casing insulation and expansion joint material
- Asbestos rope, cloth, and tape used for sealing and repair work

VA Benefits & Legal Options for Cimarron AO-177 Veterans
Veterans diagnosed with mesothelioma, asbestosis, pleural plaques, or asbestos-related lung cancer who served aboard Cimarron AO-177 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 Cimarron AO-177 ships use asbestos?
Yes. The Cimarron AO-177 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 Cimarron AO-177 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 Cimarron AO-177 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 Cimarron AO-177?
If you or a family member served aboard Cimarron AO-177, 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.
