“The center of zeppelin production in the United States was Akron, Ohio. In 1916, the Goodyear Tire and Rubber Company purchased land near Akron to build a plant that could produce zeppelin aircraft. In 1917, the main Goodyear Company created a subsidiary known as the Goodyear Zeppelin Company to manufacture the zeppelins. That same year, the firm received a contract from the federal government to manufacture nine zeppelins for the United States military during World War I. Unfortunately for the company, its manufacturing facilities were not complete in 1917, so Goodyear completed the first airships inside of a large amusement park building in Chicago, Illinois. The military used these airships to bomb and to spy upon enemy positions.
At the conclusion of World War I, the Goodyear Tire and Rubber Company continued to manufacture zeppelins. The firm used most of these ships to advertise its products. By the late 1920s and the early 1930s, among the firm’s completed zeppelins were the Pony [1921-1923], Pilgrim , Puritan, Volunteer, Mayflower, Vigilant, Defender, Reliance, Resolute, Enterprise, Ranger, and Columbia. [late 1920s – early 1930s].”
Those zeppelins were mostly used for shore patrol. The biggest hazard was that some yahoos liked to take pot shots at them, but they proved that the airships could sustain the damage and stay afloat. [Source]
