The Gearing class was the most numerous destroyer class in US Navy history — 98 ships commissioned between 1945 and 1951 following the earlier Allen M. Sumner-class design. Gearing-class destroyers formed the backbone of the Cold War destroyer fleet, with many ships receiving Fleet Rehabilitation and Modernization (FRAM I and FRAM II) upgrades in the 1960s that extended their service lives into the 1970s and 1980s. The Gearing class served from the end of WWII through the Cold War, with the last ships decommissioning in the mid-1980s. These WWII-era ships used asbestos insulation throughout their steam engineering plants consistent with wartime and early Cold War construction standards.

WWII-Era Steam Plant Asbestos

Gearing-class destroyers used steam turbine propulsion with WWII-era asbestos insulation:

  • Boiler plant — each Gearing-class destroyer had two or three Babcock & Wilcox or Combustion Engineering boilers with asbestos lagging on exterior surfaces, asbestos combustion chamber refractory brick, and asbestos rope and packing at boiler access doors and valve packing throughout the firerooms. BT ratings maintaining the boiler plant in the confined firerooms of these 390-foot destroyers worked in direct proximity to asbestos-containing lagging throughout their engineering duty
  • Main steam piping — the main steam piping from Gearing-class firerooms to the enginerooms and to auxiliary steam consumers used asbestos magnesia pipe covering — block insulation under canvas jacket — throughout the hot steam distribution system. The concentrated and confined engineering spaces of these smaller destroyer hulls meant engineering ratings were in constant proximity to the asbestos-covered steam piping during normal watch-standing
  • FRAM modifications — the FRAM I and FRAM II upgrades of the 1960s added new equipment spaces and systems on the existing WWII hulls. Modification work disturbed the existing asbestos pipe covering and construction materials throughout the ship’s engineering spaces, generating asbestos exposure for shipyard workers and crew during modification periods

Gearing Class in the Cold War

Gearing-class destroyers served as convoy escorts, carrier screening ships, and ASW platforms:

  • The ships operated in the high-tempo Cold War destroyer fleet — North Atlantic convoy exercises, Mediterranean deployments, and Pacific operations — with engineering ratings standing sustained engineering watches in the confined firerooms and enginerooms, which were the primary asbestos exposure environments aboard ship

VA Claims for Gearing-Class Veterans

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure aboard WWII-era steam destroyers. BT and MM ratings who served aboard Gearing-class destroyers and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.

VA Presumptive Benefits — No Filing Deadline

The U.S. Department of Veterans Affairs recognizes mesothelioma, asbestos-related lung cancer, asbestosis, and pleural disease as conditions presumed to be service-connected for Navy veterans with documented asbestos exposure under 38 CFR § 3.309(d). No statute of limitations applies to VA disability compensation claims.

Available benefits may include monthly disability compensation, Dependency & Indemnity Compensation (DIC) for surviving spouses, priority VA healthcare enrollment, and Special Monthly Compensation for severe cases. Parallel claims against the asbestos bankruptcy trust funds established by the manufacturers of these products do not reduce VA compensation.

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.
