Whidbey Island Class Dock Landing Ship (LSD-41) — Asbestos in the Modern Navy Dock Ship

The Whidbey Island class dock landing ships — eight ships commissioned between 1985 and 1992, designated LSD-41 through LSD-48 — replaced the aging Anchorage class LSDs with a modern design featuring an enlarged well deck sized for the new LCAC air cushion landing craft. Built by Lockheed Shipbuilding in Seattle, Washington, Whidbey Island class LSDs use four Colt Industries diesel engines driving two shafts through reduction gears. The Whidbey Island class was designed around the LCAC air cushion landing craft capability that became the centerpiece of amphibious assault operations in the late Cold War and post-Cold War period. The earliest Whidbey Island class ships commissioned in the mid-1980s were built during the late phases of asbestos phase-out in naval construction, with the extent of asbestos-containing materials in their construction reflecting the transitional construction specifications in effect during their building. Later ships in the class commissioned in the late 1980s and early 1990s likely incorporated significantly reduced or absent asbestos-containing materials as the phase-out progressed.

Whidbey Island Class Diesel Engineering Space Construction

Early Whidbey Island class LSDs may incorporate residual asbestos:

• Diesel engine exhaust system thermal insulation — the Colt Industries diesel engine exhaust systems aboard Whidbey Island class LSDs incorporate high-temperature thermal insulation on exhaust ducting to protect surrounding ship structure. The thermal insulation materials used in the exhaust system construction of the earliest Whidbey Island class hulls reflect the construction specifications in effect at the time of their building. Engineering ratings working in early Whidbey Island class engine rooms accumulated background asbestos exposure from any asbestos-containing thermal insulation present in the exhaust system construction
• Reduction gear room and shaft alley construction — the reduction gear rooms and shaft alley spaces aboard Whidbey Island class LSDs were constructed using construction materials consistent with the mid-1980s construction specifications. Engineering ratings maintaining reduction gear equipment in Whidbey Island class gear rooms accumulated background asbestos exposure from any asbestos-containing materials in the gear room construction

Hull Interior Construction Materials

Early Whidbey Island class LSDs incorporated mid-to-late 1980s construction materials:

• Crew berthing and working space construction — Whidbey Island class LSDs commissioned in the mid-1980s incorporated interior construction materials in crew berthing compartments and working spaces consistent with the construction specifications of the period. Crew members serving aboard early Whidbey Island class ships accumulated background asbestos exposure from any residual asbestos-containing construction materials in the hull interior

VA Claims for Whidbey Island Class Veterans

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure from Navy dock landing ship service. Crew members who served aboard early Whidbey Island class dock landing ships and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.
