Navy Fleet Oilers Asbestos Exposure Lawsuit
For much of the 20th century, U.S. Navy Fleet Oilers (AO-class) were constructed with extensive use of asbestos-based materials in their engine systems, cargo pumping stations, and onboard infrastructure. These vital support ships transported fuel and lubricants to combat vessels across the globe—but the very sailors who kept the fleet moving were unknowingly exposed to asbestos fibers. Many later developed mesothelioma, asbestosis, or asbestos-related lung cancer due to their service aboard AO-class ships.
Our legal team helps Navy oiler veterans and their families pursue compensation through asbestos trust fund claims, lawsuits, and VA benefits—with no upfront legal fees and no risk.
Why Asbestos Was Used Heavily Aboard Fleet Oilers (AO)
Navy oilers transported highly flammable liquids under extreme conditions. Asbestos was used to reduce fire risk, contain heat, and protect the ship’s infrastructure. It was found in:
-
Insulation for steam pipes, boilers, and fuel lines
-
Fireproofing around pump rooms, engine spaces, and control panels
-
Electrical systems and control wiring
-
Decks, bulkheads, and ventilation systems throughout the ship
Asbestos was especially prevalent in tight machinery spaces, where sailors were regularly exposed during routine operations and maintenance.
Fleet Oiler Classes Where Asbestos Was Heavily Used
| Fleet Oiler Class | Example Ships |
|---|---|
| Cimarron-Class (AO) | USS Cimarron (AO-22), USS Neosho (AO-23) |
| Mispillion-Class (AO) | USS Mispillion (AO-105), USS Caloosahatchee (AO-98) |
| Neosho-Class (AO) | USS Neosho (AO-143), USS Mississinewa (AO-144) |
| Henry J. Kaiser-Class (T-AO) | USNS Henry J. Kaiser (T-AO-187), USNS Big Horn (T-AO-198) |
These ships were packed with asbestos materials from the keel to the superstructure.
Number of U.S. Service Members Exposed to Asbestos on Fleet Oilers (AO)
Fleet oilers contained asbestos insulation in boilers, pipes, and fuel systems. Crew members faced exposure during operation and maintenance of these vital supply ships.
| Oiler Class | Estimated Number of Service Members Exposed |
|---|---|
| Cimarron-Class (WWII) | Approximately 30,000 sailors served aboard Cimarron-class oilers with heavy asbestos use. |
| Henry J. Kaiser-Class (Modern) | Around 20,000 personnel served on Kaiser-class oilers with asbestos exposure during early years. |
Total Estimated Exposure: Over 50,000 personnel served on asbestos-containing fleet oilers.
