The DN-1 was the US Navy's first airship. The contract was awarded on 1 June 1915 to the Connecticut Aircraft Company of New Haven CT. The DN-1 was roughly based on the German Parseval type of non-rigid airship. The envelope was made of two layers of cloth with rubber between them as well as on the inside and outside. The gondola control car built by George Lawley & Son of Dorchester Massachusetts was a large rectangular box with two four-bladed propellers on outriggers.
