North Carolina and South Dakota Class Battleships — Asbestos in WWII Fast Battleships

The North Carolina class (BB-55 USS North Carolina, BB-56 USS Washington) and South Dakota class (BB-57 USS South Dakota, BB-58 USS Indiana, BB-59 USS Massachusetts, BB-60 USS Alabama) fast battleships were commissioned 1941-1942 and served throughout World War II as carrier task force escorts in both the Atlantic and Pacific. Built at the height of the 1941-1942 naval construction surge, these battleships used asbestos insulation throughout their high-pressure steam engineering plants consistent with 1941-era naval construction standards. South Dakota class ships saw Korean War service following recommissioning, extending their active service into the early Cold War.

High-Pressure Steam Plant and Asbestos

North Carolina and South Dakota class battleships used high-pressure, high-temperature steam plants with multiple boilers:

• Eight-boiler steam plant — the North Carolina class carried eight Babcock & Wilcox high-pressure boilers in four fire rooms, generating steam for the four propulsion turbine sets. The fire room environment in 1941-era battleship construction was thoroughly insulated with asbestos on boiler casings, steam drum exterior, superheater headers, and associated high-temperature steam components
• South Dakota class boiler plant — the South Dakota class used eight or nine boilers (varying by ship) in the same fire room arrangement, with asbestos insulation throughout the boiler room equipment and steam system piping consistent with 1941-1942 construction
• Main steam piping — the extensive main steam distribution system carrying high-pressure superheated steam from fire rooms to engine rooms used asbestos pipe covering on all steam piping throughout the battleship engineering spaces
• Propulsion turbine casings — main propulsion turbines in four engine rooms had asbestos insulation on turbine casing external surfaces

Korean War Recommissioning

Several South Dakota class battleships were recommissioned for Korean War service:

• USS Wisconsin (BB-64, Iowa class) and other battleships provided gunfire support during the Korean War with engineering ratings serving in the full asbestos-insulated engineering spaces of these 1941-era battleships during Korean War combat operations
• Engineering ratings serving during Korean War recommissioning tours were in the same WWII-era asbestos-insulated engineering spaces, with no significant reduction in asbestos content from the original construction

Preserved Battleships and Historic Exposure

Several North Carolina and South Dakota class battleships are preserved as museum ships:

• USS North Carolina (BB-55) in Wilmington, NC; USS Massachusetts (BB-59) in Fall River, MA; USS Alabama (BB-60) in Mobile, AL; USS Indiana (BB-58) was scrapped. Museum ship restoration and maintenance work has involved workers with asbestos in the original battleship structure

VA Claims for North Carolina and South Dakota Class Veterans

VA evaluates asbestos-related disability claims on a case-by-case basis. Veterans generally need evidence of in-service asbestos exposure, a current asbestos-related diagnosis, and a medical link between them. Engineering ratings who served in fireroom and engine room billets aboard North Carolina and South Dakota class battleships during WWII or Korean War service and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.
