The United States Navy's lighter-than-air program was conducted at Lakehurst from its inception through the 1930s. NAS Lakehurst was the center of airship development in the United States and housed three of the U.S. Navy's four rigid airships, (ZR-1) "Shenandoah", (ZR-3) "Los Angeles", and (ZRS-4) "Akron". A number of the airship hangars built to berth these ships still survive. Hangar One, in which the "Shenandoah" was built, held the record for the largest "single room" in the world. According to an article in the January, 1925 issue of "National Geographic Magazine", the airship hangar "could house three Woolworth Buildings lying side by side." The base also housed many Navy non-rigid airships, otherwise knowns as "blimps," in several squadrons before, during, and after World War II. This included the U.S. Navy's ZPG-3W (EZ-1C), which was deactivated in September 1962. In 2006, after a 44-year hiatus, the U.S. Navy resumed airship operations at Lakehurst with the MZ-3.
