USS Shenandoah (ZR-1)
The 
USS Shenandoah, the first in a line of four 
United States Navy rigid airships, was actually based upon a crashed 
World War I era 
zeppelin: the Zeppelin Company's "L-49".  When the U.S. Navy thought about building a zeppelin of their own, they had already had blimps for some time.  A good portion of these blimps were stationed at the Lakehurst Naval Air Station in 
Lakehurst, New Jersey.  Also, the only room large enough in which to assemble a zeppelin was Hangar Number One, built in 
1921, at Lakehurst.
The USS Shenandoah took to the sky for the first time on September 4, 1923.
