Asbestos Use on Navy Escort Carriers

Navy Escort Carriers, like other U.S. Navy vessels built between the 1930s and late 1970s, relied heavily on the use of asbestos-containing materials for insulation and fireproofing.

About Navy Escort Carriers

Navy Escort Carriers (CVEs), also known as “Jeep Carriers” or “Baby Flat Tops,” were first incorporated into the U.S. Navy during World War II to replace earlier naval losses. The CVEs were smaller and less armored than the other aircraft carriers. As a result, they were faster and easier to build.

The CVEs were designed to escort allied battleships and to transport aircraft. In addition, they participated in anti-submarine warfare, combat air patrol and formed a large part of the fleet if other ships were unavailable.

The first CVEs were built on merchant hulls. After demonstrating their versatility and success, the U.S. Navy commissioned nearly 80 more vessels over the course of World War II.

The CVEs performed admirably in both the Atlantic and Pacific Theaters.  They proved especially effective at targeting German U-Boats and “milch cows” (the ships that met the submarines with supplies).

In the Pacific, they provided air cover for amphibious landings, ferried planes, resupplied the big carriers and performed tactical air strikes in support of ground forces. The thin hulls proved to be an advantage to the CVEs, the Japanese U-Boat shells would pass through without exploding.

Asbestos Use on Escort Carriers

Navy ships were very vulnerable to fire, they contained tons of gasoline, aviation fuel, diesel fuel and oil. They also carried munitions and other explosive materials.

At the time the CVEs were built, asbestos was widely recognized as the most effective fireproofing and insulative material ever employed in shipbuilding. In fact, it was seen as such an extraordinary material that during World War II the Navy mandated that it be used profusely throughout the shipbuilding process.

Many years later it was discovered that asbestos fibers were extremely toxic if they were inhaled or ingested. The Navy banned the use of asbestos in the late 1970s. Unfortunately, in the previous 5 decades, countless sailors and shipbuilders had already come into contact with the dangerous substance over the course of their service to their country.

Types of Asbestos Products Used in Escort Carriers

Asbestos was used liberally and incorporated into many different aspects of the shipbuilding process in varying concentrations.

Some of the asbestos products on escort carriers were used in:

  • Hull construction
  • Non-skid flooring on decks
  • Fire retardant on walls and bulkheads
  • Blankets used to cover boilers
  • Insulative felt covering for water pipes
  • Spray-on, block and loose-fill insulation
  • Gaskets
  • Valves
  • Pumps
  • Paint, sealant, caulking and adhesive
  • Coating for electric wiring
  • Floor and ceiling tiles
  • Fireproof protective clothing
  • Welding rods
  • Cement

High Asbestos-Risk Occupations on Navy Escort Carriers

Nearly everyone who worked within the confined quarters of the escort carriers was exposed to asbestos.


The pipes that ran throughout the ships were coated in an insulative felt wrapper. This particular material contained an asbestos concentration of 50%. The felt covering was prone to breaking down and the asbestos needles became airborne in boiler rooms, engine rooms, private sleeping quarters and common areas.

The fibers were then inhaled or ingested. The pipefitters responsible for maintaining the plumbing are at a particularly high risk for exposure.

Boiler Rooms

Boilers were needed on every CVE. The boilers were coated in asbestos for insulation and covered in asbestos-containing blankets. The boilermakers and tenders worked in cramped quarters with poor ventilation and no respiratory protection. As a result, they suffered exposure in much higher concentrations than other sailors.

Machinists and Enginemen

The mechanical pumps responsible for the bilge, heating and cooling systems all contained asbestos. The enginemen and machinists who worked on the pumps were also exposed to extremely dangerous amounts of asbestos. The machinists worked without respiratory protective equipment using sanders, wire brushes and scrapers to remove gaskets stuck inside the pumps.

Help for Navy Veterans with Mesothelioma

U.S. Navy veterans who served on escort carriers are one of the most at-risk groups for developing asbestos-related diseases such as mesothelioma.

Veterans who served on U.S. Navy escort carriers and have since developed mesothelioma may be eligible for financial compensation and healthcare benefits through the VA.
