2. Types of Ships with Asbestos
The U.S. Navy has about 430 vessels, including both ships and service craft, that are actively in service or in
reserve. Unfortunately, although the Navy issued a policy against using asbestos in ships in 1975, many veterans
had already been exposed to the cancer-causing material by that point.
The nationally recognized mesothelioma law firm of Belluck & Fox, LLP has extensive experience researching
where asbestos was used on U.S. Navy vessels, and we are here to help veterans who are now suffering health
effects from their exposure years ago. For more information, check out our FAQ page now.

3. Aircraft Carriers
U.S Navy aircraft carriers were critically important during wartime, helping shape the strategy of combat. Able to
hold more than 3,000 soldiers and as long as 1,100 feet, these mobile air bases are the largest warships ever
constructed. They are indispensable platforms that help greatly extend the military’s reach, enabling it to launch
airstrikes against any target, anywhere in the world. The Navy lists more than 60 aircraft carriers that have
served the U.S. military, with 10 of those currently active and two more under construction.
Aircraft Carriers
Ammunition Ships
Used to deliver important supplies to combatant ships at sea, U.S. Navy ammunition ships carry more than
ammunition and missiles. They also transport food, parts for repairs, and small amounts of fuel, when necessary.
Due to the dangers of carrying such volatile cargo, though, these ships aim to make deliveries in safe spots at

and they continue to serve our country today.

5. Amphibious Warships
As the name indicates, amphibious warships – commonly referred to as “gator freighters” – travel on water in
support of ground assaults. In addition to transporting troops, they host aircraft, carry landing craft, and provide
suppressive fire and cover for other ships. Amphibious warships were first used widely during World War II due
to the complexity of coastal area campaigns. The overarching “Gator Navy,” as it’s called, includes: amphibious
assault ships; amphibious command ships; amphibious transport dock; command ships; dock landing ships;
landing craft, air cushioned; and landing craft, mechanized and utility.
Amphibious Warships
Battleships
Battleships have served a vital role throughout the history of naval conflict. Although U.S. Navy battleships were
the most important vessels in the fleet prior to World War II, advancements in weapons technology made them
largely obsolete by the early 1940s. Far too vulnerable to mines, aircraft and torpedoes, these grand ships were
LIVECHAT

6. largely replaced by aircraft carriers in the Second World War and completely decommissioned by the 1990s.
Over the course of its history, the U.S. Navy commissioned 59 battleships.

LIVECHAT

7. Cruisers
Cruisers took on the role of direct-combat surface ships as production of battleships ceased in the later 20th
century. Each of these large, powerful vessels served its own specialized function, including guided missile
cruisers, aircraft cruisers, battlecruisers and command cruisers. Although a few remain in service, these ships
were critically important to the U.S. Navy fleet throughout much of the 1900s. The U.S. Navy currently has an
aging force of 22 cruisers.
Cruisers
Destroyers
Destroyers are built largely for speed and elusiveness and are therefore smaller than cruisers and battleships.
The main function of a destroyer is to help defend larger vessels from attacks by quick, agile enemy craft. As
battleship production ceased and the use of cruisers began to decline, destroyers became the most heavily
LIVECHAT

8. armored and armed surface-combat ships. The U.S. Navy now boasts 72 destroyers, including 10 that are under
construction.
Destroyers
LIVECHAT

9. Destroyer Escorts
Destroyer escorts are smaller than full-size destroyers and used mainly for anti-aircraft and anti-submarine
purposes. The U.S. Navy used these small, agile vessels to help defend unarmed Merchant Marine ships during
the Second World War. They share the same design as destroyers but are not as fast. There were more than
450 of these vessels constructed after 1941. By the 1970s, destroyers became known as frigates.
Destroyer Escorts
Escort Carriers
Escort carriers provided substantial advantages over standard aircraft carriers because they were easier and
less expensive to build. The Navy was thus able to deploy these vessels, often called “baby flattops” and “jeep
carriers,” when larger carriers were unavailable. Escort carriers were mainly used during World War II to help
protect Allied convoys from attacks by German U-boats.
Escort Carriers

10. Floating Dry Docks
LIVECHAT

11. Floating dry docks are essential for the flexibility of naval operations, giving U.S. Navy vessels the ability to dock
along shores where a traditional dry dock is not an option and offering aid wherever it is needed. These crucial
service crafts assist in hauling and docking ships, as well as conducting maintenance and repairs to vessels in
isolated areas. The Navy began ramping up its fleet of floating dry docks in preparation for operations in the
Pacific during World War II. These vessels continued to be a great asset during the Korean and Vietnam wars,
and they are still used today.
Floating Dry Docks
Frigates
Frigates were mainly built during and after the Second World War. Prior to the 1970s, they were referred to as
destroyer escorts. While they were used primarily in an anti-submarine role, frigates were also used to defend
convoys. These are substantially different from prior vessels that were also known as frigates.
Frigates
LIVECHAT

12. Minesweepers
These specialized vessels were constructed with equipment that could detect, neutralize and safely remove
naval mines. Minesweepers not only save countless lives, they also help prevent damage to the U.S. Navy fleet
and keep America’s sea trade up and running. Thanks to minesweepers and mine countermeasure vessels,
crucial supply lanes remain open and vessels are able to operate freely. There are currently 11 mine
countermeasure ships in service.
Minesweepers
Seaplane Tenders
Seaplane tenders are considered the first aircraft carriers, and they became a staple in the U.S. Naval Fleet
during World War II. U.S. Navy veterans who served on seaplane tenders may have been exposed to asbestos
while working on the ships’ boilers, turbines, pumps, valves, and other equipment.

LIVECHAT

13. Submarines
Among the most well-known naval vessels, submarines are also some of the most deadly in the U.S. Navy
arsenal, able to provide tactical and strategic advantages during wartime. Submarine use dates back to World
War I, and these craft, capable of sustained underwater operation, remain a naval fleet mainstay. There are four
classes of Navy submarines: attack submarines, ballistic missile submarines, guided missile submarines, and
deep submergence rescue vehicles. Submarines range in size from small vessels built for stealth to huge ships
that can carry a crew of nearly 100 sailors.
Submarines
Tugboats
Often referred to as the “workhorse” of the harbor, tugboats have always played an important role in U.S. Navy
operations. These sturdy boats maneuver larger ships into and out of harbors, as well as tow other vessels and

harbors running smoothly and dedicated to providing aid whenever they are called upon.
Tugboats
Asbestos Equipment
T
he Navy used asbestos containing materials (ACMs) for many purposes.
According to the Department of Veterans Affairs War Related Illness & Injury Study Center, the Navy
used ACMs on ships that were built before 1983 – many of which were in service for decades afterwards.
LIVECHAT

15. ACMs were used in many materials, including boilers, turbines, pumps, gaskets, valves, cements, adhesives and
pipe coverings. They were extensively used in engine and boiler rooms.
Navy veterans were exposed to asbestos when working in very close quarters, which has resulted in an
increased risk of developing an asbestos-related illness.
The products and systems that used asbestos on Navy ships include:
Navy Veterans at Increased Risk
Navy veterans who are at an increased risk of developing an asbestos-related illness include those who:
were involved in repair of asbestos-containing equipment or removal of asbestos materials
served on ships whose keels were laid before 1983
worked in shipyards from the 1930s through the 1990s
LIVECHAT

16. Boilers
Boilers are a tank for generating steam under pressure to create electricity. Asbestos was used as insulation for
the inside and outside of the boiler. Materials for the interior were often firebrick or refractory cement. Asbestos
covering in the form of cement or thermal insulation was usually used for external insulation.
Gaskets that contained asbestos were used on different parts of the boiler including the door, various access
windows and plates, and where the boiler was connected to piping and other equipment. Asbestos packing and
gaskets were used in boiler components like soot blowers, valves, and pumps.
Boiler workers installed, repaired, and replaced asbestos insulation on the interior and exterior of the boilers,
creating clouds of dust in the vicinity. Gaskets and packing had to be inspected and changed regularly, further
exposing workers to asbestos through this dusty process.

worked as pipe fitters, welders, boiler tenders, electricians, machinists and firemen before the mid-
1990s
Unfortunately, many service members often worked directly with asbestos products in tight areas with poor
ventilation and were not provided with proper respiratory protection. For many Navy service members, this
was a deadly combination.
LIVECHAT

17. Turbines
A turbine produces continuous power, made to revolve by steam, gas, or other fluids. Asbestos insulation was
used on the interior and exterior of the turbine, often in the form of blankets or thermal insulation. Each turbine
had numerous pumps and valves which required gaskets and packing that needed to be pulled off and cleaned.
Asbestos was disturbed when workers had to repair, replace, or maintain parts around the turbines, exposing
workers.
LIVECHAT

18. Pumps
Pumps take liquid and distribute it throughout the ship. Pumps are used in various parts of ships to move water
and oil to the the turbines, generators, and other equipment.
Types of pumps include boiler feed, condensate, saltwater, main feed booster, auxiliary condensate,
auxiliary feed, drain, evaporator, flushing, brine overboard, bilge, circulating, main lube, and fire, among
others. Pumps had asbestos insulation on the outside. They also contained casing gaskets and flange gaskets.
High-pressure packing was used in glands to seal the pump.
Machinist’s Mate looked for wear and tear on the pumps. To change the packing, workers loosened the packing
gland, pulled the asbestos packing out and cleaned up the area, causing asbestos fibers to be released in the
air. Pump gaskets needed to be removed and replaced when pumps were repaired or replaced.
Pumps were opened to be cleaned and sometimes taken off the ships for cleaning, repairing, replacing, and
maintaining.
Valves
LIVECHAT

19. Valves control the passage of fluid through a pipe to different pieces of equipment throughout ships including
lube oil, globe, control, and crane valves. There were myriad valves on ships. The exterior of the valve was
insulated with asbestos. Valves also contained bonnet and flange gaskets that had asbestos and asbestos
packing to seal the stem.
Workers were exposed to asbestos when disassembling the equipment. Navy personnel would regularly fix leaks
and check lines for maintenance. A quick fix to a leaking valve stem or a leaking pump was to add asbestos
packing.
The packing material in the valve can get hard and dry after being worn. Workers would wait for the systems to
cool down, remove the packing material, cut the wire it was attached to, unwind the packing material, and take it
off. They then pulled the packing gland off and dug out the valve packing and gaskets, causing asbestos fibers to
be released in the air.
Condensers and Evaporation and Distillation Equipment
A condenser is a container that condenses vapor. Evaporators remove liquid from material. Distillers remove salt
from salt water.
Workers opened, inspected, and installed cooling condensers, evaporators, and distilling equipment, including
associated pumps and valves. Asbestos was used in gaskets and packing for this equipment as well as in the
LIVECHAT

20. equipment’s insulation.
The cooling condenser was inspected by taking all the bolts out and opening inspection hatches and doors.
Workers checked all sides of the gasketed condenser and then inspected ports on the evaporators. They then
removed the asbestos gaskets and cleaned them by scraping and brushing them, causing asbestos fibers to be
released into the air.
Machine Shop
A machine shop is a part of a shipyard where equipment is repaired.
Various valve bonnets and pump parts that contained asbestos were brought to machine shops as workers
pulled them out. They were disassembled in the machine shop and shipyard workers would repair valve seats
and pump parts.
LIVECHAT

21. Other Equipment
Many other types of equipment on ships used asbestos, including:
Insulation, gaskets and packing
Steam whistles
Heaters
Fans
Air conditioning
Refrigeration
Hot water heating
Anchor windlass
Laundry equipment
Air compressors
Galley equipment
Ice machines
When ships went into port or dry dock, extensive work was performed on the ship and its equipment. In certain
cases, major refitting and modernization projects were executed. Shipyard workers were exposed to asbestos
during ship construction and overhauls. Symptoms of asbestos disease typically take 30 to 50 years to appear,
so workers at shipyards in the 1960s or 1970s may only recently have developed mesothelioma.
Serious Health Effects of Asbestos Exposure
any Navy veterans were continually exposed to asbestos that caused them to contract asbestos-related diseases

22. M
that affect the lungs or membranes around the lungs such as respiratory cancer (lung cancer and
mesothelioma), asbestosis and other types of cancer.
The tragedy is that these illnesses could have been prevented if proper precautions had been taken to avoid
asbestos exposure. Unfortunately, asbestos manufacturers failed to provide sufficient warnings of the health
hazards of their products.
Mesothelioma
Mesothelioma affects the mesothelium, a thin membrane that covers the internal organs of the body.
Although there are several types of mesothelioma, most affect the membranes surrounding the lung (pleural
membrane) or abdominal cavity (the peritoneum).
LIVECHAT

23. Asbestosis
Asbestosis is a condition that causes lung tissue to scar and become thick, stiff and fibrotic. It can be a
progressive process and result in shortness of breath. It is often associated with a chronic cough or
bronchitis and can eventually lead to disability and death.
Lung Cancer
Lung cancer forms in the tissues of the lung, usually in the cells that line the air passages. Lung cancer from
asbestos generally does not manifest for decades after exposure.
Cigarette smoking, along with asbestos exposure, can increase the risk of lung cancer by 50 to 100 times.
LIVECHAT

24. Navy Veterans Deserve Compensation for Their Injuries
Any Navy veteran who was injured due to asbestos exposure is likely
dealing with costly cancer treatments and other medical expenses that
wouldn’t have been necessary had the asbestos companies provided
adequate warnings.
Navy veterans deserve compensation to cover these costs, and an
experienced mesothelioma attorney can analyze your situation to
determine your possible legal options against an asbestos manufacturer,
distributor or seller.
In addition to veterans who served on ships, those who worked in
shipyards may have been exposed to asbestos while building, maintaining,
or repairing vessels.
Civilian Navy shipyard workers, sometimes called yardbirds, also were at
high risk of exposure.
Other Cancers
According to the Institute of Medicine, research shows that asbestos exposure can also lead to other
cancers – especially those that affect the pharynx, larynx, stomach, colon and rectum.
