🔹 History of Asbestos Use on Navy Attack Transport Ships
Navy attack transport ships—often designated as APA (Attack Personnel Transport) or AKA (Attack Cargo Transport)—were built to carry troops, vehicles, weapons, and supplies directly into combat zones. Because these ships combined high-heat machinery, fuel systems, ammunition storage, and crowded living spaces, fire safety was a top priority. Asbestos became a standard material because it resisted fire, handled extreme heat, and was inexpensive.
Unfortunately, the same material that protected these ships later caused serious diseases in thousands of sailors and shipyard workers.
This article explains when asbestos entered attack transport construction, why it became standard, and how its use created long-term health risks.
🕰️ Early Attack Transport Design and Fire Risk
As amphibious warfare expanded in the early 1900s, the Navy needed ships that could:
• Carry large numbers of troops
• Transport vehicles and supplies
• Operate near enemy fire
• Handle fuel, explosives, and heavy machinery
These ships relied on:
• Boilers and steam systems
• Turbines and generators
• Electrical networks
• Cargo handling machinery
• Fuel and ammunition storage
All of this created intense heat and fire risk inside enclosed steel hulls.
Early insulation materials—like cork, wood, and basic mineral fibers—burned easily and failed under extreme heat. Engineers needed a material that could:
• Resist high temperatures
• Prevent fire from spreading
• Insulate steam pipes and boilers
• Protect crews from burns
• Survive saltwater conditions
Asbestos fit these needs almost perfectly.
🚢 When Asbestos Entered Attack Transport Construction
Asbestos began appearing in U.S. Navy ships in the early 1900s, but its use expanded dramatically during wartime.
Key periods:
• 1900–1915 – Early use in boiler and pipe insulation
• World War I – Expanded use in engine and steam spaces
• 1920s–1930s – Standard material in naval shipbuilding
• World War II – Massive use in nearly all APA and AKA ships
• 1950s–1970s – Continued use despite early health warnings
Most famous attack transports used in World War II and Korea were built when asbestos was considered essential.
🔥 Why Asbestos Became Standard on Attack Transport Ships
Fire Resistance
Attack transports carried fuel, explosives, vehicles, and large troop populations. Fires could kill hundreds in minutes. Asbestos did not burn, making it ideal for walls, ceilings, wiring, and machinery.
Heat Insulation
Boilers, turbines, and steam pipes ran at extreme temperatures. Asbestos insulation protected sailors and soldiers from severe burns.
Durability
These ships operated in saltwater, tropical heat, and combat conditions. Asbestos resisted moisture, chemicals, and decay.
Low Cost
Wartime shipbuilding required cheap, fast materials. Asbestos was widely available and easy to use.
Lightweight
Ship designers needed protection without excessive weight. Asbestos provided fire safety without heavy steel plating.
Because of these advantages, asbestos was promoted as a “miracle material.”
⚓ World War II: Peak Asbestos Use
World War II marked the height of asbestos use on attack transport ships.
During construction:
• Walls and ceilings were sprayed with asbestos fireproofing
• Pipes were wrapped in asbestos cloth
• Boilers were coated with asbestos cement
• Machinery was insulated with asbestos
• Cargo spaces were fireproofed with asbestos boards
Troops and sailors lived inside asbestos-lined ships every day.
🏗️ Construction and Shipyard Overhauls
Attack transports required frequent repairs and refits.
During shipyard work:
• Old asbestos insulation was stripped
• Boilers and pipes were uncovered
• New asbestos materials were installed
• Dust filled enclosed compartments
These periods created the heaviest asbestos exposure for both sailors and civilian shipyard workers.
🚨 Ignored Health Warnings
By the 1930s and 1940s, doctors had linked asbestos to lung disease. However:
• War needs outweighed health concerns
• Manufacturers downplayed risks
• The Navy trusted industry claims
• Long-term sailor studies were not done
As a result, asbestos remained standard on attack transports for decades.
📍 Where Early Attack Transports Used Asbestos
Asbestos appeared throughout attack transport ships:
• Boiler insulation and lagging
• Steam pipes and valves
• Turbines and generators
• Electrical wiring
• Fireproof bulkheads and decks
• Gaskets and seals
• Cargo handling equipment
• Troop berthing areas
• Crew quarters
• Ventilation systems
Fibers entered nearly every space onboard.
🛠️ Daily Life in an Asbestos Environment
Common exposure activities included:
• Chipping old insulation
• Replacing gaskets and valves
• Welding near asbestos-covered pipes
• Sanding fireproof walls
• Sleeping in asbestos-lined berthing areas
Ventilation systems carried fibers throughout the ship.
🔄 Maintenance and Overhauls: Highest Risk
During overhauls:
• Insulation was scraped and cut
• Boilers were opened
• Machinery coverings were removed
• Dust filled tight spaces
Many sailors experienced their worst exposure during these periods.
🧬 Long-Term Health Consequences
Asbestos diseases often appear 20–50 years later.
Common illnesses:
• Mesothelioma
• Lung cancer
• Asbestosis
• Pleural disease
Many attack transport veterans were diagnosed decades after service.
❓ Attack Transport – History FAQs
Were all attack transports built with asbestos?
Most APA and AKA ships built before the 1980s used asbestos widely.
Why was asbestos trusted so long?
It worked well and health risks were hidden or ignored.
Did sailors know it was dangerous?
Most were never warned.
Can old exposure still cause disease today?
Yes—symptoms often appear decades later.
