Sun Shipbuilding & Dry Dock Company, Chester PA

Sun Shipbuilding & Dry Dock Company (Sun Ship) was developed by Sun Oil in 1917 as a tanker builder and was in continuous operation
throughout the lean inter-war years.
At the beginning of the WWII emergency, its 8 ways were increased to 20 with $28mm from the USMC, and later to 28, making it the single
largest shipyard in the country.
At its peak it employed more than 40,000 people, organized in four adjacent yards.
The most northerly of the four, known as the #4 Yard, was manned almost exclusively by African-American workers.
After the war, the South Yard and the #4 Yard were sold for industrial development and Sun continued as a merchant shipbuilder in the Central
and North Yards.
It was sold to Pennsylvania Shipbuilding (Penn Ship) in 1982, class="special" but closed in 1989. The North Yard is now Penn Terminals, a very successful
independent cargo terminal, the only U.S. port facility that employs Boilermaker labor.
The Central Yard site has been sold or leased for multiple uses: the south end is now part of neighboring Kimberly-Clark (formerly Scott Paper),
the parking lot to the east of Morton Avenue is now a state penitentiary and the big floating dry-dock is now in Galveston; the remainder of the
Central Yard is now Harrah's Chester Casino & Racetrack. See the shipyard from the air on Google here: you can still see the old WWII building
ways in what used to be the South and #4 Yards.
