Eddystone has a history of heavy industry.
Eddystone Arsenal became the largest Baldwin Locomotive Works plant (the smaller being in Spring Garden, Philadelphia).
Baldwin was once the largest manufacturer of steam locomotives in the world.
Today an Exelon generating station occupies some of the riverfront.
The Platt-LePage Aircraft Company built some of the earliest rotorcraft on adjacent land to the northeast (outside the borough).
The site's association with military helicopters continued through McDonnell Aircraft and McDonnell Douglas all the way to the present, as a Boeing Integrated Defense Systems plant now operates there.

During World War I, Remington Arms opened the Eddystone Rifle Plant on Baldwin land with Baldwin management.
Here it produced the Pattern 1914 Enfield rifle and M1917 Enfield rifle.
A large portion of the rifles used by American soldiers in France in World War I were made at Eddystone.
In January 1918 Remington Arms was absorbed by Midvale Steel and Ordnance Company, which took over the rifle plant.

Baldwin also formed a subsidiary company (Eddystone Ammunition Corporation) in 1915 to build artillery shells (Russian-model on British order).
On 10 April 1917, 133 people were killed in an explosion at the artillery shell plant.
A monument near the Edgmont Avenue side of the Chester Rural Cemetery marks the final resting place for the remains of the unidentified victims, mostly women and young girls.

In 1917 the U.S. government also placed artillery shell orders, and bought out some of the assets of the Eddystone Ammunition Corporation.
A new corporation, the similarly named Eddystone Munitions Company, was formed by Baldwin to make the shrapnel for the shells.
