The Air Dock, as it is known, was constructed in 1929. It was the largest building in the world without interior supports and provided a huge structure in which “lighter-than-air” ships (later known as airships, dirigibles, and blimps) could be constructed. The first two airships to be constructed and launched at the Airdock were USS Akron and its sister ship, USS Macon, built in 1931 and 1933, respectively. These first two airships were approximately 785 feet in length.
