⚓ U.S. Navy — Destroyers
Benson/Gleaves DD-421
Last updated July 11, 2026
The Benson/Gleaves DD-421 was a class of U.S. Navy destroyers from the asbestos era, led by USS Benson (DD-421). Its 40 ships used asbestos-containing insulation throughout the engineering plant, and veterans who served aboard Benson/Gleaves DD-421 vessels — especially in engineering ratings — may have been exposed to asbestos fibers.

- 40 ships in the class
- Hull numbers span DD-421 to DD-617

Asbestos Exposure Aboard Benson/Gleaves DD-421 Ships
Asbestos was the standard thermal insulation material aboard U.S. Navy destroyers built before approximately 1980. On ships of this type, asbestos-containing materials were concentrated in the areas below.
- Boiler rooms — pipe lagging, boiler block insulation
- Engine rooms — turbine casing covers, pump gaskets, valve packing
- Machinery spaces — asbestos rope, cloth, and tape used for sealing
- Fire rooms — refractory brick and expansion joint packing
- Below-decks berthing near engineering spaces
Fletcher-class destroyers (DD-445 and after, commissioned 1942–1944) are the emblematic example. The Gearing class that followed, and the postwar Forrest Sherman and Charles F. Adams classes, continued to use asbestos through the 1970s.

VA Benefits & Legal Options for Benson/Gleaves DD-421 Veterans
Veterans diagnosed with mesothelioma, asbestosis, pleural plaques, or asbestos-related lung cancer who served aboard Benson/Gleaves DD-421 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 Benson/Gleaves DD-421 ships use asbestos?
Yes. The Benson/Gleaves DD-421 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 Benson/Gleaves DD-421 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 Benson/Gleaves DD-421 ships?
Common asbestos products used in U.S. Navy destroyers 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 Benson/Gleaves DD-421?
If you or a family member served aboard Benson/Gleaves DD-421, 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.
