Even though the name suggests that it is a private shipbuilding company, this is a shipyard owned by the government. It was founded during World War II and is the youngest shipyard in the U.S. Navy history. Initially, it would manufacture Liberty ships, but it subsequently began producing frigates and attack cargo ships. In 1945, the number of employees was greater than 21,200. One of the most serious issues at Walsh-Kaiser Company was asbestos exposure among employees. Because they had to handle products containing asbestos without protective equipment such as respirators, shipyard workers would inhale and ingest significant amounts of toxic fibers, which is why these people have a high risk of developing terrible diseases such as lung cancer today.
