== The Scale of WWII Shipyard Production ==
The wartime American shipbuilding mobilization was unprecedented in industrial history. In the decade before 1940, U.S. shipyards launched only 23 ships; between 1940 and 1945, that number surged to approximately 4,600 vessels — including 2,710 Liberty Ships, 414 Victory Ships, over 700 tankers, and more than 1,300 naval combat vessels.<ref name="nps_shipbuilding" /> The San Francisco Bay Area alone produced 1,400 vessels, accounting for nearly 45% of all cargo shipping tonnage built nationally.<ref name="construction_physics" />
This output was achieved through revolutionary prefabrication methods. Henry Kaiser's seven shipyards — four in Richmond, California, and three in Oregon — produced nearly 1,500 ships with a workforce of approximately 90,000, setting speed records that reduced Liberty Ship construction from 250 days to under 50.<ref name="construction_physics" /> The Brooklyn Navy Yard in New York employed 70,000 workers at peak, making it the largest industrial employer in New York State and the largest industrial center in the U.S. Navy.<ref name="bny_heritage" /> Nationwide, shipyard employment surged from approximately 168,000 in mid-1940 to over 1.5 million at the war's peak, with an estimated 4.5 million workers passing through shipyard employment during the war years.
Every one of these vessels contained asbestos in virtually every compartment — an estimated 24 to 30 tons of thermal insulation per destroyer, and up to 465 tons aboard Iowa-class battleships. Over 300 different asbestos-containing products were used aboard Navy ships between the 1930s and mid-1980s, and no shipyard provided respiratory protection or warned workers of the hazard.

Shipyard Exposure Index

Comprehensive database of U.S. naval and commercial shipyards with documented asbestos exposure, workforce statistics, and compensation claim guidance.

American shipyards employed millions of workers during the 20th century, with peak employment during World War II and the Cold War. Asbestos was used extensively in ship construction, repair, and overhaul operations from the 1930s through the 1980s, creating one of the largest occupational exposure cohorts in U.S. history.

Documented shipyard facilities: 25+ Peak combined employment: 1.5+ million workers (WWII) Primary exposure period: 1940-1980 Asbestos applications per vessel: 300+ distinct uses

The Scale of WWII Shipyard Production

The wartime American shipbuilding mobilization was unprecedented in industrial history. In the decade before 1940, U.S. shipyards launched only 23 ships; between 1940 and 1945, that number surged to approximately 4,600 vessels — including 2,710 Liberty Ships, 414 Victory Ships, over 700 tankers, and more than 1,300 naval combat vessels.[1] The San Francisco Bay Area alone produced 1,400 vessels, accounting for nearly 45% of all cargo shipping tonnage built nationally.[2]

This output was achieved through revolutionary prefabrication methods. Henry Kaiser's seven shipyards — four in Richmond, California, and three in Oregon — produced nearly 1,500 ships with a workforce of approximately 90,000, setting speed records that reduced Liberty Ship construction from 250 days to under 50.[2] The Brooklyn Navy Yard in New York employed 70,000 workers at peak, making it the largest industrial employer in New York State and the largest industrial center in the U.S. Navy.[3] Nationwide, shipyard employment surged from approximately 168,000 in mid-1940 to over 1.5 million at the war's peak, with an estimated 4.5 million workers passing through shipyard employment during the war years.

Every one of these vessels contained asbestos in virtually every compartment — an estimated 24 to 30 tons of thermal insulation per destroyer, and up to 465 tons aboard Iowa-class battleships. Over 300 different asbestos-containing products were used aboard Navy ships between the 1930s and mid-1980s, and no shipyard provided respiratory protection or warned workers of the hazard.

How Shipyard Workers Were Exposed

Asbestos was used in virtually every shipboard system:

  • Insulation — Pipe covering, boiler lagging, turbine wrapping
  • Fireproofing — Bulkhead panels, deck underlayment, cable coating
  • Gaskets — Valve packing, flange seals, pump components
  • Structural — Adhesives, cements, caulking compounds

Workers in all shipyard trades faced exposure, but those in engine rooms, boiler spaces, and insulation work faced the highest concentrations—often exceeding safe limits by 100x or more.

U.S. Navy shipyards conducted construction, repair, and overhaul of naval vessels. These facilities operated under federal authority and maintained detailed employment records now available through FOIA requests.

Commercial Shipyards

Private shipyards built vessels for commercial shipping, the Merchant Marine, and military contracts. Many operated under Emergency Shipbuilding Program contracts during WWII.

Shipyard Occupations

All shipyard workers faced asbestos exposure, but certain trades experienced the highest concentrations:

Extreme Exposure Trades

  • Insulators/Laggers — Direct asbestos handling daily
  • Boilermakers — Confined space boiler work
  • Pipefitters — Pipe insulation installation/removal
  • Ship Scalers — Surface preparation in enclosed spaces

Very High Exposure Trades

  • Electricians — Wire insulation, panel work
  • Machinists — Engine room equipment
  • Welders — Heat shielding, cutting through insulation
  • Sheet Metal Workers — Ductwork, ventilation systems

High Exposure Trades

  • Carpenters — Bulkhead installation, finishing
  • Painters — Surface preparation, coatings
  • Riggers — General construction support
  • Laborers — Cleanup, material handling

→ View Complete Occupation Database

Documenting Your Shipyard Employment

Successful claims require documentation of:

  1. Employment dates — Pay stubs, tax records, union records
  2. Job classifications — Trade, rating, department
  3. Specific vessels — Ships worked on, repair vs. new construction
  4. Asbestos contact — Products used, removal work, confined spaces

Record Sources

  • National Personnel Records Center — Federal employment verification
  • Social Security Administration — Employment history
  • Union Records — Local union membership, job dispatches
  • State Workers' Compensation — Prior injury claims
  • Shipyard Personnel Offices — Some maintain historical records

→ View Evidence Documentation Guide

Asbestos Products Used in Shipyards

Documented asbestos-containing products used in shipyard operations:

  • Johns Manville — Pipe insulation, block insulation
  • Owens Corning — Fiberglass/asbestos insulation products
  • Pittsburgh Corning — Unibestos block insulation
  • Eagle-Picher — Thermal insulation products
  • Garlock — Gaskets, packing materials
  • Crane Co. — Valves with asbestos packing

→ View Complete Products List

Compensation Pathways

Shipyard workers may recover compensation through multiple channels:

Many shipyard workers recover $500,000 to $1,500,000+ through combined trust fund claims and litigation.
