The Coontz class consisted of ten destroyer leaders (later reclassified as guided missile destroyers) commissioned between 1960 and 1961. Originally designated DLG-6 through DLG-15 and reclassified DDG-37 through DDG-46 in the 1975 reclassification, the Coontz class served as large anti-aircraft warfare escort ships for carrier battle groups. The lead ship, USS Coontz (DLG-9/DDG-40), was built at Puget Sound Naval Shipyard in Bremerton, Washington. These 512-foot steam-powered ships used two or three boilers driving steam turbines and carried extensive asbestos insulation in their engineering plants consistent with the late-1950s construction era.

Steam Plant Asbestos

Coontz-class destroyer leaders used steam turbine propulsion with asbestos insulation:

Boiler plant — the boilers aboard Coontz-class ships used asbestos boiler lagging on external surfaces, asbestos refractory brick in combustion chambers, and asbestos sealing materials at boiler access points. BT ratings maintaining the boiler plant performed lagging maintenance and boiler inspection in the confined fireroom spaces
Main steam piping — the steam distribution piping in the Coontz-class engineering spaces used asbestos magnesia pipe covering on main steam and auxiliary steam piping. The engineering spaces of these large destroyers had extensive steam piping overhead and along the bulkheads — all covered with asbestos magnesia block insulation that deteriorated under operational conditions and released asbestos fiber into the engineering space atmosphere
Engineering auxiliaries — steam-driven boiler feed pumps, ejectors, and ship’s service turbine generators used asbestos-containing gasket and packing materials in the MM and BT ratings’ maintenance routines

Coontz-Class Ships

The ten ships of the Coontz class include: Coontz (DDG-40), King (DDG-41), Mahan (DDG-42), Dahlgren (DDG-43), William V. Pratt (DDG-44), Dewey (DDG-45), Preble (DDG-46), Farragut (DDG-37), Luce (DDG-38), and Macdonough (DDG-39).

VA Claims for Coontz-Class Veterans

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure aboard steam-powered destroyer leaders. Engineering ratings who served aboard Coontz-class ships and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.

The asbestos-containing products documented on U.S. Navy vessels and at shipyards are catalogued by manufacturer on AsbestosIndex. These records cross-reference which companies supplied which materials and to which facilities.

Navy Ratings Most Exposed to Asbestos Aboard Coontz-Class Destroyer Leaders (DLG)

The U.S. Department of Veterans Affairs and the public asbestos litigation record document that the following Navy ratings worked routinely in spaces where ACM was installed, maintained, ripped out, and replaced:

Boilerman (BT) — boiler-room operations, refractory work, burner maintenance
Machinist’s Mate (MM) — main propulsion turbines, reduction gears, condensers, pumps
Engineman (EN) — auxiliary diesel and gasoline engines, gland packing
Electrician’s Mate (EM) — cable runs through asbestos-insulated chases, motor-generator sets
Hull Maintenance Technician (HT) / Pipefitter — piping system maintenance, gasket replacement, valve repacking
Damage Controlman (DC) — firefighting equipment, fire-stops, bulkhead penetrations
Fireman (FN) — engineering-plant tending across boiler and engine rooms

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.

Coontz-Class Destroyer Leaders (DLG) — Frequently Asked Questions

Are Coontz-Class Destroyer Leaders (DLG) veterans covered by Navy asbestos litigation records?

Yes. Coontz-Class Destroyer Leaders (DLG) is documented in the public U.S. Navy asbestos litigation record. U.S. Navy vessels of her service era were built to BUSHIPS specifications that required asbestos insulation throughout engineering spaces, on steam lines, around boilers and turbines, and in gasket and packing materials.

Which shipboard components on Coontz-Class Destroyer Leaders (DLG) contained asbestos?

Asbestos-containing materials documented aboard U.S. Navy vessels of Coontz-Class Destroyer Leaders (DLG)'s era include: boiler insulation and lagging, steam-line pipe insulation, turbine and reduction-gear casings, valve packing, gaskets, brake and clutch friction materials, electrical wire insulation, overhead pipe coverings in berthing and mess spaces, and Navy-issue boiler cement and refractory in fireboxes.

What ratings were exposed to asbestos serving on Coontz-Class Destroyer Leaders (DLG)?

Navy ratings with the highest documented asbestos exposure include Machinist's Mate (MM), Boiler Technician (BT), Hull Maintenance Technician (HT), Engineman (EN), Electrician's Mate (EM), Interior Communications Electrician (IC), Damage Controlman (DC), and Pipefitter / Shipfitter. Officers in engineering departments also encountered asbestos in normal duty. Shipyard workers performing overhaul, repair, or refit work had concentrated exposure during yard periods.

Do Coontz-Class Destroyer Leaders (DLG) veterans qualify for VA disability for mesothelioma?

Yes. Mesothelioma is recognized by the VA as service-connected for veterans with documented Navy service and qualifying asbestos exposure. Coontz-Class Destroyer Leaders (DLG) veterans (or surviving family) typically file at VA.gov, by phone at 1-800-827-1000, or with assistance from a Veterans Service Officer through DAV, VFW, or American Legion. Civil claims against asbestos product manufacturers are separate from VA benefits — many veterans pursue both paths.
